This is the second of two reviews—the first discussed the definition, epidemiology, and diagnosis of sepsis, whereas this one focuses on management and outcome. Management of sepsis can conveniently be divided into general supportive measures and specific treatment.
A favourable outcome depends on early, aggressive, treatment
Antimicrobial treatment must take into account both patient susceptibilities and local resistance patterns; advice from infectious disease or microbiology colleagues is often helpful
Volume resuscitation and cardiovascular support should be titrated to simple clinical end points
Subtle signs of organ hypoperfusion should be sought in physically robust patients
The role of activated protein C and low dose steroids remains to be clarified
What are the general supportive measures?
Circulatory compromise arises from the combination of vasodilatation, capillary leak, and reduced myocardial contractility, and needs early correction. Whether crystalloids or colloids are better for volume resuscitation remains unresolved. Few people now use human albumin after a controversial meta-analysis concluded that albumin was associated with a 6% excess mortality.1 A subsequent randomised controlled trial found no difference in any of the outcome measures examined, including mortality.2 Another question is how to gauge the adequacy of fluid resuscitation. The pulmonary artery catheter has not been shown to be associated with either harm or benefit,3 4 and its use is declining. Clinical end points (box 1) remain useful, although some centres are also using oesophageal Doppler or pulse contour analysis. These methods provide information on the effect of fluid loading on cardiac output and stroke volume. In ventilated patients, variation in stroke volume can be used as an index of preload.
