颅脑损伤是指因暴力直接或间接作用于头部引起的脑组织损伤,其中脑损伤后昏迷>6 h或再次昏迷者为重型颅脑损伤,临床表现为意识障碍、头痛、恶心、呕吐、癫痫发作、肢体瘫痪、感觉障碍、失语及偏盲等。近年来,随着交通、运输业的发展,颅脑损伤发生率呈逐年上升趋势,严重影响人们的生命健康和生活质量。
高压氧可有效改善重型颅脑损伤患者临床症状,减轻患者脑水肿,促进昏迷患者清醒,具有较好的临床效果[1-2]。计算机断层扫描(CT)具有扫描时间快、图像清晰等特点,是临床常用的影像学检测方法[3-5]。本研究旨在探讨高压氧治疗重型颅脑损伤患者的临床效果,现报道如下。
1.1 一般资料 选取2012—2015年陕西省第二人民医院收治的重型颅脑损伤患者146例,其中失访29例,本研究实际纳入患者117例,经颅脑CT或磁共振成像(MRI)检查确诊。纳入标准:(1)有明确创伤史;(2)格拉斯哥昏迷量表(GCS)评分3~8分;(3)病程<1个月。排除标准:(1)存在严重多发伤者;(2)存在心、肺、肝、肾等重要脏器功能不全者;(3)昏迷时间<6 h或GCS评分>8分者;(4)临床明确诊断为植物状态者;(5)存在高压氧治疗禁忌证者。采用随机数字表法将所有患者分为对照组53例与观察组64例。两组患者性别、年龄、损伤类型比较,差异无统计学意义(P>0.05,见表1),具有可比性。本研究经陕西省第二人民医院医学伦理委员会审核批准,患者家属均签署知情同意书。
1.2 方法 对照组患者予以常规治疗,包括护脑、脱水、降颅压、抗感染以及对症处理等。观察组患者在对照组基础上予以高压氧治疗,仪器为YC3200型空气加压舱,治疗期间压力维持0.2 MPa,升压15~20 min,稳压70~80 min,减压20~25 min,1次/d,4周为1个疗程;对意识障碍患者予以头罩直接供氧,意识清醒且能配合治疗患者采用面罩吸氧。两组患者均连续治疗8周。
1.3 观察指标 (1)血肿面积:两组患者治疗前后采用西门子SomotonBR 3型CT仪进行扫描,电压设定为125 kV,电流设定为350 mA,层厚设定为8 mm,间距设定为8~10 mm;检查结果由放射科医师集体读片后写出报告。(2)Loewenstein认知评定量表(LOTCA)评分:治疗前后采用LOTCA评估两组患者认知功能,包括定向、知觉、视组织运动、思维运作、注意与集中5方面,LOTCA评分越高表明患者认知功能越好。

2.1 血肿面积 治疗前两组中脑挫裂伤、硬膜外出血、硬膜下出血、蛛网膜下腔出血患者血肿面积比较,差异无统计学意义(P>0.05);治疗后观察组中脑挫裂伤、硬膜下出血、蛛网膜下腔出血患者血肿面积分别小于对照组中脑挫裂伤、硬膜下出血、蛛网膜下腔出血患者,差异有统计学意义(P<0.05),但两组中硬膜外出血患者血肿面积比较,差异无统计学意义(P>0.05,见表2)。
2.2 LOTCA评分 治疗前两组患者定向评分、知觉评分、视组织运动评分、思维运作评分、注意与集中评分比较,差异无统计学意义(P>0.05);治疗后观察组患者定向评分、知觉评分、视组织运动评分、思维运作评分、注意与集中评分高于对照组,差异有统计学意义(P<0.05,见表3)。

重型颅脑损伤是临床常见的急危重症,其会影响血-脑脊液屏障功能导致颅内压升高,造成脑水肿、坏死,进而引发微循环障碍、脑组织缺血缺氧,且随着病情进展可能发生脑疝,严重威胁患者的生命安全[6-7]。因此,及时、有效地纠正重型颅脑损伤患者脑组织缺血、缺氧可预防脑组织出现不可逆损伤。
研究表明,高压氧治疗重型颅脑损伤的临床效果较好[8-10]。高压氧治疗可通过提高重型颅脑损伤患者血氧张力及血氧含量、增加有效弥散距离而改善缺血、缺氧脑组织供血及微循环,促进毛细血管再生和侧支循环形成,进而发挥保护病灶区及周围神经元的作用[11];同时,重型颅脑损伤患者早期予以高压氧治疗,一方面可通过收缩脑血管、增强血管阻力、降低血管通透性而减轻脑水肿,另一方面可通过提高血液、脑组织及脑脊液氧分压而降低颅内压,从而切断脑缺氧-脑水肿-代谢障碍恶性循环,最大限度地促进脑组织功能恢复;高压氧治疗还能促进重型颅脑损伤患者脑神经干细胞释放,从而加速脑功能重组[12-16]。
本研究结果显示,治疗后观察组中脑挫裂伤、硬膜下出血、蛛网膜下腔出血患者的血肿面积小于对照组中脑失传裂伤、硬膜下出血、蛛网膜下腔出血患者,但两组中硬膜外出血患者的血肿面积间无差异,提示高压氧治疗可减少重型颅脑损伤患者的血肿面积。本研究利用CT对重型颅脑损伤患者高压氧治疗前后血肿面积进行评估,对早期诊断和提高重型颅脑损伤患者预后具有重要意义;且由于CT检查具有准确率较高、操作方便快捷等优点,故CT检查可能在诊断和评估重型颅脑损伤方面具有广泛应用前景。本研究结果还显示,观察组患者定向评分、知觉评分、视组织运动评分、思维运作评分、注意与集中评分高于对照组,与相关研究结果一致[17-18],提示高压氧治疗可改善重型颅脑损伤患者的认知功能。
综上所述,高压氧治疗重型颅脑损伤的临床效果确切,可有效缩小血肿面积,改善患者认知功能,值得临床推广应用。但本研究样本量较小,观察指标较少,结果结论仍有待扩大样本量、增加观察指标等进一步研究证实。
