Effect of head-low-foot-high position on the postoperative brain reexpansion of chronic subdural hematoma

Objective To investigate the effect of head-low-foot-high position on the degree of brain tissue resuscitation in patients with chronic subdural hematoma (CSDH) after operation. Methods One hundred and seventy-eight CSDH patients admitted to the Neurosurgery Department of the First Affiliated Hospital of Xinjiang Medical University from June 2012 to December 2015 were divided into 3 groups according to the record of medical records: control group (recumbent position after operation), treatment group 1 (head-low-foot-high position after operation, foot high position about 15°), treatment group 2 (head-low-foot-high position after operation, foot high position about 30°). The relapsing degree of brain tissue and the recurrence rate of hematoma were compared before the drainage tube was removed and 1 month after operation. Results Before the drainage tube was removed, there was a significant difference among 3 groups(P 0.05). Follow up for 6 months to 6 years showed that the recurrence rate of hematoma in the treatment group was significantly lower than that in the control group (2.4% vs 11.1%, P<0.05). Conclusion Patients with CSDH take head-low-foot-high position after operation can promote the reexpansion of brain tissue and reduce the recurrence rate of hematoma.
