Characteristics of the Patients Preoperatively and Intraoperatively
hematoma, hematomas, Coma
HEMATOMA, HEMATOMAS, COMA
Abbreviations: BT, body temperature; CT, computed tomography; RT, room temperature.Total numbers less than 277 for the RT group or less than 264 for the BT group indicate missing data.Patients often presented with more than 1 symptom.Glasgow Coma Scale scores range from 3 to 15, where the higher scores correlate with a better clinical status.Combinations of different CT appearances are possible.A total of 219 of 264 patients (83%) in the BT group and 235 of 277 patients (85%) in the RT group had a CT scan of the brain performed at 2 months after surgery. If the patient developed symptoms consistent with a recurrent or residual cSDH, CT was done earlier than the planned 2-month follow-up visit. Overall, 118 of 219 patients (54%) in the BT group and 148 of 235 patients (63%) in the RT group had some residual hematoma on their CT. Most residual hematomas detected by CT at the planned control at 2 months were small and without clinical significance. As expected, symptomatic hematomas requiring reoperation were larger (mean [SD] size, 19.1 [2.7] mm in the BT group; 18.3 [3.2] mm in the RT group) compared with the asymptomatic, nonoperated hematomas (mean [SD] size, 7.6 [4.6] mm in the BT group; 7.5 [5.1] mm in the RT group).
