title: Coagulase-negative staphylococcal bacteraemia with special reference to septic shock: experience in an intensive care unit.
abstract: During a period of 4.5 years, 48 patients with bacteraemia due to coagulase-negative staphylococci were studied prospectively in order to evaluate their clinical profile, management and outcome. There were 25 males and 23 females with ages ranging between 13 and 100 years. Over 60% of patients belonged to the age group 30 to 69 years. Shock was recorded in 23 (48%) of the 48 patients. Of the shocked patients, 16 were immunocompromised and also had abnormal coagulation. Their mortality was 44%. By contrast, none of the immunocompromised patients without shock died. Abnormal coagulation was found in 17 patients without septic shock. Their mortality was 5.9%. The commonest underlying disease was respiratory failure especially in shocked patients. The source of infection was identified in the majority of cases. In addition, most patients had an indwelling intravascular catheter especially an arterial one. The overall mortality was 16.7% (8/48). It was significantly higher in patients with shock than in those without shock (30.4% vs. 4.0%, P < 0.05).
