140例脑脓肿分析

An analysis of 140 brain abscesses.

本文回顾性分析我院从1980～1991年常规应用CT后140例脑脓肿的诊治。最常见的病因为隐源性感染,多房、多发性及直径小于2cm的小脓肿发生率升高。最常见的需氧菌是金黄色葡萄球菌和变形杆菌,厌氧菌为消化链球菌和脆弱拟杆菌;多种细菌混合感染占29％。13例保守治疗者无1例死亡,反复穿刺、引流及脓肿切除术之间死亡率无显著性差异,总死亡率为7.1％;死亡率高低与入院时意识状态最为密切。

One hundred and forty patients with brain abscess were reviewed after CT scaning used routinely from 1980 to 1991. Cryptogenic infection was the most common etiology. Multiple and multilocular abscesses and abscess smaller than 2cm in diameter were found mostly. The commonest aerobic bacterium were staphylococcus aureus and proteus species. The commonest anaerobic bacterium were peptostreptococci and bacterioides fragilis. The rate of multiple bacteria infection was 29%. No death occurred among 13 patients with conservative treatment. There was no significant difference in mortality in various operative methods. The overall mortality rate 7.1%, and was related closely with initial neurological grade.
