目的预防俯卧位脊柱侧弯矫治手术患者球结膜水肿。方法将86例脊柱侧弯矫治手术患者按手术时间先后排序分为两组各43例,对照组采用常规俯卧位手术,观察组在常规俯卧位基础上适时采用头高足低俯卧位。观察两组手术不同时间的眼压及术后球结膜水肿发生率。结果两组术前眼压比较,差异无统计学意义(P>0.05);手术不同时间眼压比较,干预主效应、时间主效应和交互效应均P<0.05;手术结束时观察组球结膜水肿发生率显著低于对照组(P<0.05)。结论适时采用头高脚低俯卧位可有效缓解脊柱侧弯矫治手术患者术中眼压升高,预防球结膜水肿的发生。
Objective To prevent conjunctival edema in patients undergoing surgery for prone position scoliosis. Methods Eighty-six patients undergoing scoliosis correction surgery were divided into two groups according to the operation time, and the control group was treated with conventional prone position. The observation group was given proper head, high and low prone position on the basis of the usual prone position. The intraocular pressure and the incidence of conjunctival edema at different times of operation were observed. Results There was no significant difference in preoperative intraocular pressure (P> 0.05) between the two groups (P> 0.05). The intraocular pressure at different times of operation, main effect of intervention, main effect of time and interactive effect were all P <0.05; at the end of operation, The incidence was significantly lower than that of the control group (P <0.05). Conclusions The timely use of head-high and low prone position can effectively relieve the intraocular pressure and prevent the occurrence of conjunctival edema in patients undergoing scoliosis correction surgery.
