Objective:
To review the clinical profiles and therapies instituted for patients with severe malaria admitted to an ICU.
Design:
Retrospective study.
Setting:
Internal ICU of a tertiary care centre.
Patients And Participants:
Between January, 1992, and February, 1999, 104 patients with malaria were admitted to the General Hospital of Vienna. Sixty-nine patients suffered from Plasmodium falciparum malaria (66%), seven of these were admitted to the ICU.
Measurement And Results:
Seven patients were admitted to the ICU, of whom three died (4% in hospital case-fatality rate). Four patients required mechanical ventilation because of respiratory insufficiency and adult respiratory distress syndrome (ARDS), of whom three died. Three patients were treated with inhaled nitric oxide (NO) and kinetic therapy; one patient required extracorporeal veno-venous oxygenation. All patients who died required haemofiltration because of acute renal failure.
Conclusion:
As P. falciparum is a potentially life-threatening disease, reliable criteria for ICU admission should be defined and risk factors identified. Early ICU monitoring should be attempted, especially under the following conditions: (1) lack of clinical response to anti-malarial treatment within 48 h and/or (2) any signs of neurological disturbance (hypoglycaemia excluded). Prospective multicentre trials and guidelines for supportive intensive care are urgently needed.
