超声在颅脑损伤术中急性脑膨出时的应用

目的探讨超声检查在重型颅脑损伤开颅术中急性脑膨出时应用价值。方法比较重型颅脑损伤开颅术中出现脑膨出时行床边超声检查组与CT检查组．对比分析两组发现颅内再出血阳性率、开颅手术时间及6月后功能恢复的差异。结果超声检查组与CT检查组在发现颅内再出血阳性率无显著性差异（x2=0．183，P〉0．05）；超声检查组手术时间显著低于CT检查组（x^2=4．861，P〈O．05）；超声检查组术后神经功能恢复显著优于CT检查组（x^2=6．593，P〈O．05）。结论术中超声检查可及时判断急性脑膨出的原因，并为清除颅内血肿实施导向，能避免遗漏血肿、缩短手术时间，对提高手术效果、改善患者预后有重要临床意义。

Application of intraoperative ultrasonography during traumatic brain injury surgery with acute encephalocele

Objective To investigate the application of intraoperative ultrasonography and to determine the cause of acute encephalocele dur- ing traumatic brain injury surgery. Methods The correct diagnosis of delayed intracranial hemorrhage, surgery time and clinical outcome at 6- month follow-up were analysed comparatively between the intraoperative uhrasonography group and computed tomography （CT） group in patients with acute encephalocele during traumatic brain injury surgery. Results The difference of correct diagnosis rate of delayed intracranial hemorrhage was not significantly between ultrasonography and CT group （X2=0.183, P〉0.05）; The surgery time in ultrasonography group was significantlyt lower than CT group （X2=4.861, P〈0.05）; The clinical outcome of intraoperative ultrasonography group is better than that of CT group （X2=6.593, P〈0.05）. Conclusion Intraoperative uhrasonography can determine the cause of acute encephalocele quickly, decrease the surgery time and play a important role in improvement of clinical outcome for patients with traumatic brain injury.
