A retrospective study of subdural hematoma was conducted in 36 patients ranging in age from 2 months to 9 years. Hypotension occurred in 41% of the children during the evacuation of the subdural hematoma. This study suggests that hypovolemia was caused, in part, by the blood loss into the subdural hematoma. In patients with hematoma larger than 8% of the intravascular volume, the frequency of the hypotension was high (88%). Infants, in particular, had larger hematomas, ranging in size from 8-27% of intravascular blood volume and, therefore, were at high risk to develop hypotension. These larger hematomas may be due to the infants' higher ratio of subdural space to the body weight. The study also suggests that the preoperative infusion of adequate fluid and blood is a significant factor in preventing hypotension during the hematoma evacuation.
对36例年龄在2个月至9岁之间的硬膜下血肿患者进行了一项回顾性研究。在硬膜下血肿清除过程中，41%的儿童出现了低血压。该研究表明，血容量减少部分是由血液流入硬膜下血肿所致。在血肿大于血管内容量8%的患者中，低血压的发生率较高（88%）。尤其是婴儿，其血肿较大，范围为血管内血容量的8%至27%，因此发生低血压的风险很高。这些较大的血肿可能是由于婴儿硬膜下腔与体重的比例较高。该研究还表明，术前输注足够的液体和血液是预防血肿清除过程中低血压的一个重要因素。
