The Risk Factors Affecting Ultra-Early Rebleeding In Patients with Spontaneous Subarchnoid Hemorrhage

ABSTRACT

Spontaneous subarachnoid hemorrhage(SAH) is a cause of high mortality and morbidity in the emergency department. Rebleeding has been well investigated, and it is now recognized that early operation can prevent rebleeding. However, ultra-early rebleeding, which may occur prior to early operation(within 24 hours after admission), worsens the clinical outcome of patients with SAH. To determine the risk factors of ultra-early rebleeding in patients with spontaneous SAH before early operation, we analyzed the cases of 383 patients admitted within 24 hours after their last attack of SAH between 1994 to 1996. In this analysis, diagnosis of rebleeding before admission was defined only if the patients experienced a definite clinical deterioration once more after an attack suggesting SAH. After admission patients who observed a sudden neurological deterioration were subject to repeat CT scanning and rebleeding was diagnosed only when new hemorrhage was observed on the CT scan in comparison with the previous scan. 45 cases(11.7%) of 383 patients had ultra-early rebleeding. The incidence of ultra-early rebleeding significantly increased in the patients who admitted hospital within 2 hours after attack. The incidence of ultra-early rebleeding also increased in the old-age group(70 years or more), patients with high systolic blood pressure, those who underwent angiography within 6 hours of the last SAH, and patients who had poor neurological condition.
