Observation On Effect Of Different Temperatures Of Flushing Fluid For Treating Chronic Subdural Hematoma

Objective To explore the clinical efficacies of different temperatures of flushing fluid in the treatment of chronic subdural hematoma(CSDH)to provide a basis for the selection of flushing fluid temperature in the treatment methods of CSDH.Methods This study was a prospective study.According to the random number table,90 patients with CSDH in this hospital during 2016-2018 were divided into the observation group and control group,with 45 cases in each group.The YL-1 type hard-channel drilling drainage was performed in both groups.The observation group was given the hypothermia(10 ℃)flushing fluid for conducting the exchange flushing,while the control group was given the flushing fluid for conducting the exchange flushing under the operating room temperature(about 20-23 ℃).The incidence rate of complications,degree of early brain reexpansion and hematoma recurrence rate were compared between the two groups.Results The gap between the brain tissue and dura on postoperative 7 d in the observation group was(2.38±0.81)cm,which in the control group was(2.85±1.26)cm,the early brain reexpansion in the observation group was significantly better than that in the control group,and the difference between the two groups was statistically significant(P <0.05).The recurrence rate in postoperative 3 months in the observation group was 2.22%,which in the control group was 13.33%,the difference between the two groups was statistically significant.(P <0.05);there was no statistically significant difference in the incidence rates of postoperative headache,acute intracranial hematoma and intracranial pneumatosis between the two groups(P >0.05).Conclusion Using hypothermia flushing fluid in the Y1-type puncture needle hard channel drilling drainage has the advantages of good brain reexpansion rate and low recurrence rate.
