利多卡因静脉预处理预防桡动脉穿刺疼痛的临床研究

摘要

Objective To research the effects of lidocaine pretreatment reduces the pain induced by radial artery puncture. Methods Eighty parturients underwent radial artery puncture was randomly divided into two groups (40 cases in each group). After occluding venous drainage using a tourniquet, the control group received 3 mL of 0.9%sodium chloride solution, the lidocaine group received 30 mg of lidocaine(3 mL). Two minutes later, the rubber tourniquet was released for arteriopuncture, the degree of pain and satisfaction of parturients was assessed and recorded. Results In experimental group, the visual analogue scale (VAS) was signiifcantly lower than control group and the patient's overall satisfaction was improved (P<0. 01). Conclusion Pretreatment with lidocaine after occluding venous drainage was effective for preventing pain and increasing patient's overall satisfaction during radial artery puncture.%　　目的探讨利多卡因静脉预处理预防桡动脉穿刺疼痛的效果。方法需行单次桡动脉采血的患者80例随机分为两组，每组40例。静脉阻断后对照组静脉预注生理盐水3 mL，利多卡因组预注利多卡因30 mg（3 mL），2 min后松开橡皮止血带即行同侧桡动脉穿刺采血。评估两组患者桡动脉穿刺导致的疼痛程度和对操作的满意度。结果利多卡因预处理组桡动脉穿刺所致的疼痛评分显著低于对照组（P＜0.01)，患者满意度显著高于对照组（P＜0.01)。结论局部静脉阻断后静脉预注30 mg利多卡因能有效缓解桡动脉穿刺导致的疼痛，提高患者满意度。
