[Septic shock in a Tunisian intensive care unit: mortality and predictive factors. 100 cases].

This is a retrospective study, of 100 consecutive patients with septic shock hospitalized in the ICU of Mongi Slim Hospital La Marsa between January 1997 and December 2001. The state of shock was defined according to the criteria established by the American College of Chest physicians in conjunction with the Society of Critical Care Medicine during the consensus conference on sepsis. Our study shows that septic shock affect both sexes in the same way, that it increases with the age and with the existence of underlying diseases. The global mortality was 82%. According to our study o, septic shock mortality in creases with age and with the existence of an underling pathological condition such as high blood pressure. It also increases with the cause of the septic shock. (Pleuro-pulmonary).

[Tracheotomy or prolonged tracheal intubation for long-term ventilation].

130 critically ill patients undergoing long term mechanical ventilation were divided into two groups, tracheotomy versus translaryngeal intubation. There were no difference in demographic characteristics between the two groups. The incidence of chronic obstructive pulmonary disease (COPD) was also higher in T. The tracheotomy was achieved at mean within 14 days after the beginning of mechanical ventilation. The incidence of pneumonia is the same in the two groups (41% for T versus 39% for I). The length of mechanical ventilation is longer in T (25 +/- 12 d versus 12 +/- 4 d). The COPD represent a risk factor for prolonged mechanical ventilation in T (18 days in COPD patients with tracheotomy versus 9 days in non COPD patients). The length of stay in intensive care unit is higher in T (29 +/- 13 d versus 15 +/- 4 d). The 28th day mortality is similar between the two groups. The tracheotomy didn't allow a shorter duration of mechanical ventilation. That's can be explain by the fact that we performed the tracheotomy in a high risk population for pulmonary complications (COPD) and often after a first failure of weaning form mechanical ventilation.

[Isolated acute renal failure is not associated to an increase in mortality of patients in intensive care units].

This study assess the prognostic factors increasing mortality of patients with acute renal failure in intensive care units. The study included 923 patients admitted to the intensive care unit over a period of two years. Acute renal failure was defined by the following criteria, a blood urea concentration of more than 30 mmol/l, a serum creatinine concentration of more than 180 micromol/l or creatinine clearance less than 50 ml/min. Patients were divided into two groups survivors (V) and dead patients (D). 95 patients presented acute renal failure with a mortality rate of 57.9%. There was no difference between the two groups. There was no difference between the two groups. Patients in intensive care units with only acute renal failure doesn't have a worse prognosis, but the association to two or more other organ dysfunction's, mechanical ventilation of more that 12 days, sepsis or Glasgow coma scale less than 8 are predictive of mortality.
