Severe sepsis is a major cause of morbidity and mortality in the critically ill patient. Management involves identification and treatment of the underlying causative infection, with antimicrobial agents and surgery where necessary, haemodynamic resuscitation with fluids and vasoactive agents, steroids (for septic shock) and immunomodulation with drotrecogin-alpha (activated), where not contraindicated. Every effort must be made to identify sepsis early so as to optimise the patient's chances of a good outcome.

Albumin reduces morbidity in acutely ill hospitalized patients. Concomitant administration of albumin in the control group can obscure the effects of albumin on clinical outcome in randomized trials.

The attitude of a Jehovah's Witness patient refusing a blood transfusion during an exsanguinating episode can raise important ethical problems. Various ethical principles, including the patient's autonomy, the sanctity of life and the dignity of the medical profession can be confronted. A total of 242 doctors, members of the European Society of Intensive Care Medicine, answered a questionnaire indicating that 63% would transfuse in those circumstances. However, 26% would never inform the patient about this. Only 45% considered the blood transfusion as appropriate, of whom 25% were unable to define the best option. Doctors from France and Italy more commonly transfuse while those from The Netherlands, the United Kingdom and Scandinavia more commonly withhold transfusion. These data stress the need for a definition of the appropriate medical attitudes towards the patient refusing blood transfusion.
The type of fluid that should be infused in the critically ill patient remains controversial. In the presence of normal lungs, maintenance of the colloid osmotic pressure (COP) can limit the development of pulmonary edema when the hydrostatic pressure is raised. When the permeability of the lung capillaries is altered, the influence of the type of fluid on the lung function becomes minimal. The larger increase obtained in extravascular fluids by the use of crystalloids could limit the availability of cellular oxygen. Nevertheless, differences in morbidity and mortality have not been related to the type of fluid infused, suggesting that the amount of fluid is a more important factor.
This study explored the hemodynamic effects of amrinone, a phosphodiesterase inhibitor, in association with intravenous fluids, in the treatment of endotoxin shock. Mongrel dogs were anesthetized with pentobarbital and mechanically ventilated with room air. Treatment was started 30 min after slow intravenous administration of 3 mg/kg of E. coli endotoxin. In the first part of the study, ten dogs were resuscitated for 30 min with intravenous saline alone (10 ml/kg) and for the next 3 h by saline (10 ml/kg/h) and amrinone 40 micrograms/kg/min. During this latter period, arterial pressure remained stable while cardiac output significantly increased from 3.1 +/- 0.5 to 5.2 +/- 0.7 l/min (P less than 0.01), and oxygen delivery increased from 616 +/- 92 to 983 +/- 156 ml/min (P less than 0.01). Comparison with control animals revealed that amrinone infusion prevented the decrease in left ventricular stroke work and markedly increased oxygen delivery. In the second part of the study, 18 dogs were treated by saline infusion titrated to maintain pulmonary artery balloon-occluded pressure at baseline level. In ten dogs, amrinone was added 60 min after endotoxin administration at a dose of 40 micrograms/kg/min. Total amount of fluids infused averaged 87 +/- 14 ml in the amrinone-treated dogs and 64 +/- 15 ml in the control dogs (differences nonsignificant). Oxygen delivery and oxygen consumption increased significantly in the amrinone-treated dogs (from 541 +/- 36 to 1063 +/- 176 ml/min, P less than 0.01, and from 145 +/- 23 to 202 +/- 38 ml/min, P less than 0.01, respectively) but not in the control dogs. The amrinone-treated dogs had lower PaO2 and higher venous admixture than the control dogs.(ABSTRACT TRUNCATED AT 250 WORDS)
Selective V1aR agonism appears to be superior to the V1aR/V2R agonist arginine vasopressin and single norepinephrine infusion for hemodynamic support in septic shock.
