At high doses, granulocyte destruction is seen. A major effect of endotoxin, particularly at the level of the hepatocyte, may be to liberate tumour necrosis factor TNF in the macrophages. Toxins derived from necrotic tissue or bacteria, either directly or via activation of the complement system, stimulate platelets, mast cells and basophils to secrete histamine and serotonin.

Changes after injury may lead to excessive production of oxygen free radicals, with deleterious effects on organ function. Adrenaline, noradrenaline, cortisol and glucagon are increased, and certain others are decreased. The sympathetic-adrenal axis is probably the major system by which the body's response to injury is activated. Many of the changes are due to adrenergic and catecholamine effects, and catecholamines are increased after injury. The major efferent pathways of the hypothalamus are endocrine, via the pituitary, and the efferent sympathetic and parasympathetic systems.

The pituitary gland responds to trauma with two secretory patterns. Adrenocorticotrophic hormone ACTH , prolactin and growth hormone levels increase. The remainder are relatively unchanged. Pain receptors, osmoreceptors, baroreceptors and chemoreceptors stimulate or inhibit ganglia in the hypothalamus to induce sympathetic nerve activity.

Why I Chose Emergency Medicine - 4th Year Medical Student

The neural endplates and adrenal medulla secrete catecholamines. Pain stimuli via the pain receptors 10 Manual of Definitive Surgical Trauma Care also stimulate secretion of endogenous opiates, Pendorphin and pro-opiomelanocortin precursor of the ACTH molecule , which modifies the response to pain and reinforces the catecholamine effects. The 3-endorphin has little effect, but serves as a marker for anterior pituitary secretion.

Hypotension, hypovolaemia in the form of a decrease in left ventricular pressure, and hyponatraemia stimulate secretion of vasopressin, antidiuretic hormone ADH from the supra-optic nuclei in the anterior hypothalamus, aldosterone from the adrenal cortex, and renin from the juxtaglomerular apparatus of the kidney.

As osmolality increases, the secretion of ADH increases, and more water is reabsorbed, thereby decreasing the osmolality negative feedback control system. Hypovolaemia stimulates receptors in the right atrium and hypotension stimulates receptors in the carotid artery. This results in activation of paraventricular hypothalamic nuclei, which secrete releasing hormone from the median eminence into capillary blood, which stimulates the anterior pituitary to secrete ACTH.

ACTH stimulates the adrenal cortex to secrete cortisol and aldosterone. Changes in glucose concentration influence the release of insulin from the 3 cells of the pancreas, and high amino-acid levels influence the release of glucagon from the a cells. Plasma levels of growth hormone are increased. However, the effects are transitory and have little long-term effect. The degree is related to the severity of injury. The function of glucocorticoid secretion in the initial metabolic response is uncertain, because the hormones have little direct action, and primarily they seem to augment the effects of other hormones such as the catecholamines.

In the later phases after injury, a number of metabolic effects take place. Glucocorticoids exert catabolic effects such as gluconeogenesis, lipolysis and amino-acid breakdown from muscle. Catecholamines also participate in these effects by mediating insulin and glucose release and the mobilization of fat. There is an increase in aldosterone secretion, and this results in a conservation of sodium and, thereby, water.

Catecholamines are released in copious quantities following injury, primarily stimulated by pain, fear and baroreceptor stimulation. The insulin response to glucose in normal individuals is reduced substantially with alpha-adrenergic stimulation, and enhanced with beta-adrenergic stimulation. The renin-angiotensin mechanism is the most important. When the glomerular arteriolar inflow pressure falls, the juxtaglomerular apparatus of the kidney secretes renin, which acts with angiotensinogen to form angiotensin I.

This is converted to angiotensin II, a substance that stimulates production of aldosterone by the adrenal cortex. Reduction in sodium concentration stimulates the macula densa a specialized area in the tubular epithelium adjacent to the juxtaglomerular apparatus to activate renin release.

An increase in plasma potassium concentration also stimulates aldosterone release. Volume decrease and a fall in arterial pressure stimulate release of ACTH via receptors in the right atrium and the carotid artery. It also produces inhibition of aldosterone secretion, which minimizes kaliuresis and causes suppression of ADH release. Prior to the discovery of ANF, it was suggested that a hormone - a third factor - was secreted following distension of the atria, which complemented the activity of two known regulators of blood pressure and blood volume: the hormone aldosterone and filtration of blood by the kidney.

ANF has also emphasized the heart's function as an endocrine organ. ANF has great therapeutic potential in the treatment of intensive care patients who are undergoing parenteral therapy. Resuscitation physiology 11 2. There is an increase in the metabolic rate, with an increase in oxygen consumption, increased protein catabolism and hyperglycaemia.

The cardiac index may exceed 4. Decreases in vascular resistance accompany this increased cardiac output. This hyperdynamic state elevates the resting energy expenditure to more than 20 per cent above normal. In an inadequate response, with a cardiac index of less than 2. Endotoxins and anoxia may injure cells and limit their ability to utilize oxygen for oxidative phosphorylation.

The amount of adenosine triphosphate ATP synthesized by an adult is considerable. However, there is no reservoir of ATP or creatinine phosphate and therefore cellular injury and lack of oxygen result in rapid deterioration of processes requiring energy, and lactate is produced. Because of anaerobic glycolysis, only two ATP equivalents instead of 34 are produced from 1 mol of glucose in the Krebs' cycle. Lactate is formed from pyruvate, which is the end product of glycolysis.

It is normally reconverted to glucose in the Cori cycle in the liver. However, in shock, the oxidation reduction redox potential declines and conversion of pyruvate to acetyl coenzyme A for entry into the Krebs' cycle is inhibited. Lactate therefore accumulates because of impaired hepatic gluconeogenesis, causing a severe metabolic acidosis. A persistent lactic acidosis in the first 3 days after injury not only correlates well with the ISS, but also confirms the predictive value of lactic acidosis in subsequent adult respiratory distress syndrome ARDS.

Total body oxygen consumption VO 2 is increased. These reactions produce heat, which is also a reflection of the hyperdynamic state. Secretion of ADH from the supra-optic nuclei in the anterior hypothalamus is stimulated by volume reduction and increased osmolality. The latter is due mainly to increased sodium content of the extracellular fluid. Volume receptors are located in the atria and pulmonary arteries, and osmoreceptors are located near ADH neurons in the hypothalamus.

ADH acts mainly on the connecting tubules of the kidney, but also on the distal tubules to promote reabsorption of water. Aldosterone acts mainly on the distal renal tubules to promote reabsorption of sodium and bicarbonate and increased excretion of potassium and hydrogen ions.

Aldosterone also modifies the effects of catecholamines on cells, thus affecting the exchange of sodium and potassium across all cell membranes. The release of large quantities of intracellular potassium into the extracellular fluid may cause a significant rise in serum potassium, especially if renal function is impaired. Retention of sodium and bicarbonate may produce metabolic alkalosis, with impairment of the delivery of oxygen to the tissues. This is as a result of both increased mobilization and decreased uptake of glucose by the tissues. Glucose is mobilized from stored glycogen in the liver by catecholamines, glucocorticoids and glucagon.

Glycogen reserves are limited, and glucose can be derived from glycogen for only 12—18 hours. Thereafter, gluconeogenesis is stimulated by corticosteroids and glucagon. The suppressed insulin favours the release of amino acids from muscle, and these are 12 Manual of Definitive Surgical Trauma Care then available for gluconeogenesis.

Growth hormone inhibits the effect of insulin on glucose metabolism. Thyroxine also accelerates gluconeogenesis, but T3 and T4 levels are usually low or normal in severely injured patients. As blood glucose rises during the phase of hepatic gluconeogenesis, blood insulin concentration rises, sometimes to very high levels. Provided that the liver circulation is maintained, gluconeogenesis will not be suppressed by hyperinsulinaemia or hyperglycaemia, because the accelerated rate of glucose production in the liver is required for clearance of lactate and amino acids, which are not used for protein synthesis.

This period of breakdown of muscle protein for gluconeogenesis and the resultant hyperglycaemia characterize the catabolic phase of the metabolic response to trauma. The glucose level following trauma should be carefully monitored. Hyperglycaemia may exacerbate ventilatory insufficiency, and may provoke an osmotic diuresis and hyperosmolality. Control of the blood glucose is best achieved by titration with intravenous insulin, based on a sliding scale. However, because of the degree of insulin resistance associated with trauma, the quantities required may be considerably higher than normal.

Parenteral nutrition may be required, and this may exacerbate the problem. However, glucose remains the best energy substrate following major trauma: per cent of the caloric requirements should be supplied by glucose, with the remainder being supplied using a fat emulsion. Fat The principal source of energy following trauma is adipose tissue. Because of the suppression of insulin release by the catecholamine response after trauma, as much as g of fat may be broken down daily after severe trauma.

Catecholamines and glucagon activate adenyl cyclase in the fat cells to produce cyclic adenosine monophosphate cAMP. This activates lipase, which promptly hydrolyses triglycerides to release glycerol and fatty acids. Growth hormone and cortisol play a minor role in this process as well. Glycerol provides substrate for gluconeogenesis in the liver, which derives energy by p-oxidation of fatty acids, a process inhibited by hyperinsulinaemia.

Ketones are released into the circulation and are oxidized by all tissues except the blood cells and the central nervous system. Ketones are water soluble and will pass the blood—brain barrier freely, permitting rapid central nervous system adaptation to ketone oxidation. Free fatty acids provide energy for all tissues and for hepatic gluconeogenesis. Canitine, synthesized in the liver, is required for the transport of fatty acids into the cells. There is a limit to the ability of traumatized patients to metabolize glucose, and a high glucose load makes management of the patient much more difficult.

For this reason, nutritional support of traumatized patients requires a mixture of fat and carbohydrates. Amino acids The intake of protein by a healthy adult is between 80 and g of protein - g protein kg-1 day This is equivalent to g of nitrogen per day. In the absence of an exogenous source of protein, amino acids are principally derived from the breakdown of skeletal muscle protein.

Following trauma or sepsis, the release rate of amino acids increases by three to four times. This process appears to be induced by PIF, which has been shown to increase by as much as eight times in these patients. The process manifests as marked muscle wasting. Cortisol, glucagon and catacholamines also play a role in this reaction. The mobilized amino acids are utilized for gluconeogenesis or oxidation in the liver and other tissues, but also for synthesis of acute-phase proteins required for immunocompetence, clotting, wound healing and the maintenance of cellular function.

Certain amino acids, such as glutamic acid, asparagine and aspartate, can be oxidized to pyruvate, producing alanine, or to a-ketogluterate, producing glutamine. The others must first be deaminated before they can be utilized. In the muscle, deamination is accomplished by transamination from branched chain amino acids. In the liver, amino acids are deaminated by urea that is excreted in the urine. Since 1 g of urea nitrogen is derived from 6.

Resuscitation physiology 13 One gram of muscle protein represents 5 g wet muscle mass. The patient in this example would be losing g of muscle mass per day. A loss of 40 per cent of body protein is usually fatal, because failing immunocompetence leads to overwhelming infection. Cuthbertson3 showed that nitrogen excretion and hypermetabolism peak several days after injury, returning to normal after several weeks. This is a characteristic feature of the metabolic response to illness. The most profound alterations in metabolic rate and nitrogen loss occur after burns.

To measure the rates of transfer and utilization of amino acids mobilized from muscle or infused into the circulation, the measurement of central plasma clearance rate of amino acids CPCR-AA has been developed. The protein-depleted patient can be improved dramatically by parenteral or enteral alimentation provided adequate liver function is present. Amino-acid infusions in patients who ultimately die cause plasma amino-acid concentration to rise to high levels with only a modest increase in CPCR-AA. This may be due to hepatic dysfunction caused by anoxia or toxins liberated by bacteria responsible for sepsis.

The gut The intestinal mucosa has a rapid synthesis of amino acids. Depletion of amino acids results in atrophy of the mucosa, causing failure of the mucosal antibacterial barrier. This may lead to bacterial translocation from the gut to the portal system and is probably one cause of liver injury, overwhelming infection and multisystem failure after severe trauma. Food intake is invariably interrupted after major trauma. The supply of glutamine may be insufficient for mucosal cell growth, and there may be an increase in endotoxin release, bacterial translocation and hypermetabolism.

Early nutrition within hours and early enteral rather than parenteral feeding may prevent or reduce these events. The hormones that contribute to anabolism are growth hormones, androgens and 17ketosteroids. The utility of growth hormone and also, more recently, of insulin-like growth factor IGF-1 in reversing catabolism following injury is critically dependent on adequate caloric intake. Hypovolaemia due to both external losses and internal shifts of extracellular fluid seems to be the major initiating trigger for the metabolic sequence. Fear and pain, tissue injury, hypoxia and toxins from invasive infection add to the initiating factors of hypovolaemia.

The degree to which the body is able to compensate for injury is astonishing, although sometimes the compensatory mechanisms may work to the patient's disadvantage. Adequate resuscitation to shut off the hypovolaemic stimulus is important. Once hormonal changes have been initiated, the effects of the hormones will not cease merely because hormonal secretion has been turned off by replacement of blood volume. Thus, once the metabolic effects of injury have begun, therapeutic or endogenous restitution of blood volume may lessen the severity of the metabolic consequences but cannot prevent them.

Mobilization and storage of the energy fuel substrates, carbohydrate, fats and protein are regulated by insulin, balanced against catecholamines, cortisol and glucagon. However, infusion of hormones has failed to cause more than a modest response. Rapid resuscitation, maintenance of oxygen delivery to the tissues, removal of devitalized tissue or pus, and control of infection are the cornerstones. The best metabolic therapy is excellent surgical care. Therapy should be aimed at removal of the factors triggering the response. Thorough resuscitation, elimination of pain, surgical debridement and, where necessary, drainage of abscesses and appropriate antibiotic administration, coupled with respiratory and nutritional support to aid defence mechanisms are of fundamental importance.

Although the basic definition of shock - 'insufficient nutrient flow' — remains inviolate, six types of shock are recognized, based on a distinction not only in the pathophysiology but also in the management of the patients: 1 2 3 4 5 6 hypovolaemic, cardiogenic, cardiac compressive cardiac tamponade , inflammatory previously septic shock , neurogenic, obstructive mediastinal compression. It is characterized by significant decreases in filling pressures with a consequent decrease in stroke volume.

Cardiac output is temporarily maintained by a compensatory tachycardia. With continuing hypovolaemia, the blood pressure is maintained by reflex increases in peripheral vascular resistance and myocardial contractility mediated by neurohumoral mechanisms. Hypovolaemic shock is divided into four classes Table 2. When the blood volume loss exceeds 30 per cent Class III and Class IV shock , the compensatory mechanisms are no longer effective and the decrease in cardiac output causes a decreased oxygen transport to peripheral tissues.

These tissues attempt to maintain their oxygen consumption by increasing oxygen extraction. Eventually, this compensatory mechanism also fails and tissue hypoxia leads to lactic acidosis, hyperglycaemia and failure of the sodium pump, with swelling of the cells from water influx. Clinical presentation The classic features of hypovolaemic shock are hypotension, tachycardia, pallor secondary to vaso- constriction, sweating, cyanosis, hyperventilation, confusion and an oliguria.

Cardiac function can be depressed without gross clinical haemodynamic manifestations. The heart shares in the total body ischaemic insult. Systemic arterial hypotension increases coronary ischaemia, causing rhythm disturbances and decreased myocardial performance. As the heart fails, left ventricular end-diastolic pressure rises, ultimately causing pulmonary oedema. Later, pulmonary insufficiency may supervene from alveolar collapse and pulmonary oedema, resulting from damaged pulmonary capillaries, cardiac failure or inappropriate fluid therapy.

Renal function is also critically dependent on renal perfusion. Oliguria is an inevitable feature of hypovolaemia. During volume loss, renal blood flow falls correspondingly with the blood pressure. Anuria sets in when the systolic blood pressure falls to 50 mmHg.

Urine output is a good indicator of peripheral perfusion. Cardiac function is impaired in such shocked patients even if myocardial damage is not the primary cause. Reduced myocardial function in shock includes dysrhythmias, myocardial ischaemia from systemic hypertension and variations in blood flow, myocardial lesions from high circulatory levels of catecholamines, angiotensin and possibly a myocardial depressant factor. The reduced cardiac output can be a result of: Table 2. Other forms of cardiogenic shock include clinical examples in which the patient may have a nearly normal resting cardiac output but cannot raise the cardiac output under circumstances of stress, because of poor myocardial reserves or an inability to mobilize those myocardial reserves due to pharmacologic 3-adrenergic blockade, for example propanolol for hypertension.

Heart failure and dysrhythmias are discussed in depth elsewhere in this book. Clinical presentation The clinical picture will depend on the underlying cause. Clinical signs of peripheral vasoconstriction are prominent, pulmonary congestion is frequent, and oliguria is almost always present. Pulmonary oedema may cause severe dyspnoea, central cyanosis and crepitations audible over the lung fields , and lung oedema visible on X-rays.

The signs on cardiac examination depend on the underlying cause. A systolic murmur appearing after myocardial infarction suggests mitral regurgitation or septal perforation. Haemodynamic findings consist of a systolic arterial pressure less than 90 mmHg, decreased cardiac output usually less than 1. Sometimes, cardiogenic shock occurs without the PAWP being elevated. This may be a result of diuretic therapy or plasma volume depletion by fluid lost into the lungs. Patients with relative hypovolaemia below the levels at which there is a risk of pulmonary oedema and patients with significant right ventricular infarction and right heart failure will also not have elevated PAWP.

These patients, although their shock is cardiogenic, will respond dramatically to plasma volume expansion and will deteriorate if diuretics are given. The consequence of this compression is an increase in right atrial pressure without an increase in volume, impeding venous return and provoking hypotension. Clinical presentation Cardiac tamponade usually follows blunt or penetrating trauma. As a result of the presence of blood in the pericardial sac, the atria are compressed and cannot fill adequately.

The systolic blood pressure is less than 90 mmHg, there is a narrowed pulse pressure and a pulsus paradoxus exceeding 10 mmHg. Distended neck veins may be present, unless the patient is hypovolaemic as well. Heart sounds are muffled. Endotoxin can have a major effect on this form of peripheral pooling and, even though the blood volume is normal, the distribution of that volume is changed so that there is insufficient nutrient flow where aerobic metabolism is needed.

In the ultimate analysis, all shock leads to cellular defect shock. Aerobic metabolism takes place in the cytochrome system in the cristae of the mitochondria. Oxidative phosphorylation in the cytochrome system produces high-energy phosphate bonds by coupling oxygen and glucose, forming the freely diffusable by-products carbon dioxide and water. Several poisons uncouple oxidative phosphorylation, but the most common in clinical practice is endotoxin.

Sepsis is very frequent in hospitalized patients, and endotoxic shock is distressingly common. There is fever; tachycardia may or may not be present; the mean blood pressure is usually below 60 mmHg, yet the cardiac output varies between 3 and 6 L m-2 min This haemodynamic state is indicative of low peripheral vascular resistance. The ultimate cause of death in septic shock is failure of energy production at the cellular level, as reflected by a decline in oxygen consumption.

It is not only the circulatory insufficiency that is responsible for this, but also the impairment of cellular oxidative phosphorylation by endotoxin or endogenously produced superoxides. There is a narrowing of arterial—mixed venous oxygen difference as an indication of reduced oxygen extraction, which often precedes the fall of cardiac output. Anaerobic glycogenolysis and a severe metabolic acidosis due to lactacidaemia result. The mechanisms responsible for the phenomena observed in sepsis and endotoxic shock are discussed above.

The cardiac output is normal, or may even be elevated, but because the total peripheral resistance is reduced, the patient is hypotensive. The consequence is reduced perfusion pressure. A very simple example of this type of shock is syncope Vasovagal syncope'. It is caused by a strong vagal discharge resulting in dilatation of the small vessels of the splanchnic bed. The next cycle of the heart has less venous return, so that the ventricle will not fill and the next stroke volume will not adequately perfuse the cerebrum, causing a faint.

No blood is lost but there is a sudden increase in the amount of blood trapped in one part of the circulation where it is no longer available for perfusion to the obligate aerobic glycolytic metabolic bed — the central nervous system. The pulse pressure is wide, with both systolic and diastolic blood pressures being low. The diagnosis of neurogenic shock should only be made once other causes of shock have been ruled out, because the common cause is injury, and there may be other injuries present causing a hypovolaemic shock in parallel.

Because of the decreased venous return, the atrial filling is reduced, with consequent hypotension. Clinical presentation In the patient with hypotension, the problem can usually be identified immediately, from decreased breath sounds, hyperresonance of the affected side, and displacement of the trachea to the opposite side. Neck veins may be distended. This universal flow formula is not dependent on the type of fluid and is applied to the flow of electrons. In electricity, it is expressed as Ohm's law. However, the focus should remain on flow rather than on pressure, because most drugs that result in a rise in pressure do so by raising the resistance, which in turn decreases flow.

Three factors determine cardiac output: The patient may have weakly palpable peripheral pulses, warm extremities and brisk capillary fill- 1 preload, or the volume entering the heart, 2 contractility of the heart, and 18 Manual of Definitive Surgical Trauma Care 3 afterload, or the resistance against which the heart must function to deliver the nutrient flow. These three factors are interrelated to produce the systolic ejection from the heart.

Up to a point, the greater the preload, the greater the cardiac output. As myocardial fibres are stretched by the preload, the contractility increases according to the Frank—Starling principle. The preload is a positive factor in cardiac performance up the slope of the Frank—Starling curve but not beyond the point of cardiac decompensation. Contractility of the heart is improved by inotropic agents.

The product of the stroke volume and the heart rate equals the cardiac output. Cardiac output acting against the peripheral resistance generates the blood pressure. Diminished cardiac output in patients with pump failure is associated with a fall in blood pressure. To maintain coronary and cranial blood flow, there is a reflex increase in systemic vascular resistance to raise blood pressure. An exaggerated rise in systemic vascular resistance can lead to further depression of cardiac function by increasing ventricular afterload.

Afterload is defined as the wall tension during left ventricular ejection and is determined by systolic pressure and the radius of the left ventricle. Left ventricular radius is related to end-diastolic volume, and systolic pressure to the impedance to blood flow in the aorta, or total peripheral vascular resistance. As the emphasis in the definition of shock is on flow, we should be looking for ways to measure flow. It keeps nutrient flow constant by lowering the resistance even though the pressure has decreased.

This allows selective shunting of blood to the renal bed. If the blood pressure falls further and a true decrease in flow across the glomeruli occurs, the rennin—angiotensin mechanism is triggered. Renin from the juxtaglomerular apparatus acts upon angiotensin from the liver.

The peptide is cleaved by renin and a decapeptide results, which, in the presence of converting enzyme, clips off two additional amino acids to produce the octapeptide angiotensin II, one of the most potent vasopressors known. The third step is that the same octopeptide stimulates the zona glomerulosa of the adrenal cortex to secrete aldosterone, which causes sodium retention and results in volume expansion. When all three compensatory mechanisms have failed, there is a decrease in the quality and quantity of urine as a function of nutrient flow to this organ.

Urine flow is such an important measurement of flow in the patient in shock that we can use this to define the presence or absence of shock. For practical purposes, if the patient is producing a normal quantity of normal quality urine, he or she is not in shock. Another vital perfusion bed that reflects the adequacy of nutrient flow is the brain itself.

Because adequate nutrient flow is a necessary, but not the only, requirement for cerebration, consciousness can also be used to evaluate the adequacy of nutrient flow in the patient with shock. However, probably the most important clinical observation to indirectly determine adequate nutrient flow to a visceral organ is the urine output. The kidney responds to decreased nutrient flow with several compensatory changes to protect its own perfusion. If Between the groin or axillae and the heart, the veins do not have any valves, so measurement of the pressure in this system at the level of the heart will reflect the pressure in the right atrium, and therefore the filling pressure of the heart.

Thus, placement of a central venous line will allow measurement of the hydrostatic pressure of the right atrium. The actual measurement is less important than the change in value, especially in the acute resuscitation of a patient. Normal is cmH2O. A value below 4 cmH2O indicates that the Resuscitation physiology 19 venous system is empty, and thus the preload is reduced, usually as a result of dehydration or hypovolaemia; whereas a high value indicates that the preload is increased, either as a result of a full circulation or due to pump failure.

As a general rule, if a patient in shock has both systemic arterial hypotension and central venous hypotension, the shock is due to volume depletion. On the other hand, if central venous pressure is high though arterial pressure is low, shock is not due to volume depletion and is more likely to be due to pump failure. Cannulation of the central venous system is generally achieved using the subclavian, jugular or femoral route. The subclavian route is the preferred one in the trauma patient, particularly when the status of the cervical spine is unclear.

It is ideal for the intensive care setting, where occlusion of the access site against infection is required. It provides ease of access, especially under operative conditions. However, the ability to occlude the site, particularly in the awake patient in the intensive care unit ICU , is more limited and there is greater discomfort for the patient.

The femoral route is easy to access, especially when the line will also be used for venous transfusion. However, the incidence of femoral vein thrombosis is high, and the line should not be left beyond 48 hours. Systemic arterial pressure Systemic arterial pressure reflects the product of the peripheral resistance and the cardiac output. Measurement can be indirect or direct. Indirect measurement involves the use of a blood pressure cuff with auscultation of the artery to determine the systolic and diastolic blood pressures. Direct measurement involves placement of a catheter into the lumen of the artery, with direct measurement of the pressure.

In patients in shock, with an elevated systemic vascular resistance, there is often a significant difference obtained between the two measurements. Failure to recognize this may lead to dangerous errors in therapy. The arterial Doppler can be used for measuring arterial blood pressure. Only measurement of the systolic blood pressure is possible. However, the Doppler correlates well with the direct measurement pressure.

The sites for cannulation vary. The radial artery is the most common site; it is usually safe to use, provided adequate ulnar collateral flow is present. It is important both medically and legally to do an Allen Test, compressing both radial and ulnar arteries and releasing the ulnar artery to check for collateral flow. Thrombosis of the radial artery is quite common, although ischaemia of the hand is rare. The dorsalis pedis artery is generally quite safe. Cannulation of the brachial artery is not recommended because of the potential for thrombosis and for ischaemia of the lower arm and hand.

Pulmonary arterial pressure8,9 The right-sided circulation is a valveless system through which flows the entire cardiac output from the right side of the heart. Catheterization can be performed easily and rapidly at the bedside, using a balloon-tipped flowdirected thermodilution catheter.

In its passage from the superior vena cava through the right atrium, from which it migrates into the right ventricle on a myocardial contraction, the balloon tip enters the pulmonic valve exactly like a pulmonary embolus, until the balloon-tipped catheter wedges in the pulmonary artery. Additional side holes are provided in the catheter, allowing measurement of pressure in each rightsided chamber, including right arterial pressure, right ventricular pressure, pulmonary and pulmonary wedge pressure.

Surgery publications, University of Otago, Christchurch, University of Otago, New Zealand

The tip of the catheter is placed in the pulmonary artery, and then the occlusive balloon is inflated. This has the effect of occluding the lumen. As a result, the pressure transmitted via the catheter represents pulmonary venous pressure and, thus, left arterial pressure. The wedged pulmonary arterial pressure is a useful approximation of left ventricular end-diastolic pressure LVEDP.
