靶控输注技术在眼底手术镇静中的应用及护理

Application of target controlled infusion in eye ground surgery sedation and nursing

目的探讨靶控输注技术在眼底手术镇静中的应用效果及护理经验，规范眼底手术的围术期护理。方法将70例患者随机分为靶控组和对照组各35例，靶控组予丙泊酚1．2μg／ml血浆浓度靶控输注，对照组以同容量生理盐水代替。结果靶控组球后阻滞2min术中血压（MAP）为（83．4±12．1）mmHg、对照组为（96．8±15．7）mmHg，两组比较差异有统计学意义（t=5．35，P〈0．05）；同时点靶控组脑电双频指数（BIS）为（83±4），对照组为（95±2），两组比较差异有统计学意义（t=6．23，P〈0．05）。靶控组术后随访满意度达98％。结论眼底手术时靶控输注丙泊酚1．2μg／ml，并给予细致的围手术期护理，可减少术中应激反应，保持患者术中生命体征稳定，提高患者满意度。

Objective To explore the nursing experiences of target controlled infusion applying in eye ground surgery sedation, and to form standard nursing care of peri-operation. Methods Seventy patients were randomly divided into experimental group and control group, 35cases per group. Experimental group received propofol target control infusion and its plasma concentration was 1.2 mierogram/ml; while control group received normal saline target control infusion instead. Results After retrobulbar nerve block 2 minutes during operation, blood pressure（MAP） of experimental group was（83.4 ± 12.1 ）mm Hg, control group was（96.8± 15.7）mm Hg, and the difference was statistically significant （ t = 5. 35, P 〈 O. 05 ）. Meanwhile, bispeetral index （ BIS ） of experimental group was （83 ~4） and control group was （95± 2 ）, the difference was statistically significant （t = 6. 23 ,P 〈 0. 05 ）. Patients＇ satisfaction degree of post-operation follow-up was 98% in experimental group. Conclusions Application of propofol target controlled infusing in eyeground operation with a target plasma concentration of 1.2 mierogram/ml can reduce stress reaction, keep vital signs of patients stable during operation, and raise the patients＇ satisfaction degree.
