Hypotension and bleeding with various anatomic patterns of blunt splenic injury in adults.
A retrospective study of 112 consecutive adult patients with blunt splenic lacerations was performed. All of the patients had operative grading of the splenic injuries according to a prospective protocol. Data on preoperative hypotension (systolic blood pressure of less than 100) and intraoperative splenic bleeding were collected from hospital records. Patients with subcapsular hematomas were excluded. Over-all, 55.4 per cent of the patients with splenic lacerations were hypotensive preoperatively and 76.6 per cent were noted to be bleeding from the spleen at operation. For injuries not involving the hilum, seven of 22 of the patients with Grade I injuries were hypotensive preoperatively versus 19 of 29 of the patients with Grade IV injuries (p = 0.025). Fourteen of 21 patients with Grade I injuries were noted to be bleeding at operation. Seventeen of 23 with Grade IV injuries were noted to be bleeding. This difference was not significant. Of the patients with injuries involving the hilum, 25 of 38 were hypotensive preoperatively and 25 of 29 were noted to be bleeding at operation. No difference in the incidence of hypotension or bleeding was found between superficial and deep hilar injuries. No significant difference was found between the active bleeding with hilar and nonhilar injuries (p = 0.19). For isolated splenic injuries (N = 36), the incidence of hypotension was 39 per cent. However, 79 per cent of the patients with isolated splenic injuries were noted to be bleeding at operation. Of 49 patients with nonisolated splenic injuries who had been hypotensive preoperatively, 72.9 per cent were found to be bleeding at operation. Of the 27 patients never hypotensive preoperatively, 78 per cent were noted to be bleeding at operation (NS). For isolated splenic injury also, no relationship was found between preoperative hypotension and the presence of operative bleeding. No significant correlation was found between preoperative hypotension or the anatomic grade of splenic injury and the incidence of bleeding found at operation. Even if computed tomographic scans can reliably grade splenic injuries, anatomic grade may not be a predictor of clinical behavior. Hypotension also failed to predict the occurrence of continued splenic bleeding.
