Abstract：Objective To investigate the relationship between subdural drainage time and recurrence of chronic subdural hematoma(CSDH).Methods The clinical data of 114 patients with CSDH treated by single burr hole drainage from March 2017 to October 2022 were retrospectively analyzed.According to the postoperative drainage time,the patients were divided into three groups:0～8 h group(n=47),9～16 h group(n=33)and 17～24 h group(n=34).The patients were followed up for 90 days to observe the recurrence of hematoma.Results Recurrence of hemotoma occurred in 20 patients,including 14 patients(29.79%)in 0～8 h group,4(12.12%)in 9～16 h group and 2(5.88%)in 17～24 h group.Four patients died,including 3 patients(6.38%)in 0～8 h group and 1(2.94%)in 17～24 h group.The recurrence rate of hematoma in the 0～8 h group was significantly higher than those in the 9～16 h and 17～24 h groups(P<0.05),but there was no significant difference in mortality among the three groups(P>0.05).Multivariate logistic regression analysis showed that shorter drainage time was an independent risk factor for postoperative hematoma recurrence(P<0.05).Conclusions Early termination of subdural drainage in patients with CSDH after burr hole drainage is associated with an increased risk of hematoma recurrence.Early monitoring of postoperative subdural drainage time and prevention of early drainage termination may help reduce the recurrence rate of hematoma.
