Abstract :

Objective: To determine predictive factors for mortality from hemorrhagic stroke in the Medical–Surgical Intensive Care Unit of the Teaching Hospital Tambohobe Fianarantsoa.

Materials and methods: This was a descriptive retrospective study of 33 months on patients with hemorrhagic stroke confirmed by a ain scan. The following parameters were studied: age, sex, Glasgow scale at entry, time to perform CT scan, topography of lesions, secondary intracranial lesions such as mass effect, hydrocephalus and ventricular flood, hyperthermia, hyponatremia, hyperglycemia, decrease of oxygen saturation (SpO₂ < 95%), pneumopathy, bedsore and hospital mortality.

Results: We selected 50 patients. The average age was 59.2 years (34 years to 80 years). The sex ratio was 1.3. Loss of consciousness was the main reason for consultation in 35 cases (70%). The mortality rate was 48% (n = 24). Fourteen patients (28%) had a Glasgow scale of ≤ 8 with a mortality rate of 71.4% (10 deaths out of 14 patients) (p = 0.039). Factors associated with mortality were hyperthermia and decrease in SpO₂. Ventricular flood was the secondary intracranial lesion that provided mortality (p = 0.001).

Conclusion

Predictors of hemorrhagic stroke mortality were Glasgow score ≤ 8, ventricular flood, hyperthermia, and decreased SpO₂. Staff training in the prevention of secondary cereal injury of systemic origin could improve the prognosis of our patients.
