摘要
目的评价异丙酚注射痛预测术后疼痛程度的准确性。方法拟行无痛人工流产手术的患者71例，年龄20—40岁，ASAⅠ或Ⅱ级。以0．5ml／s的速率静脉输注1％异丙酚2mg／kg，当异丙酚给药量达1／3时暂停给药，采用口语等级量表评分法（VRS）评价异丙酚注射痛，VRS评分≥1分为发生注射痛，之后再给予剩余量异丙酚完成麻醉诱导。术后20min时采用VAS评分法评价患者静卧以及下床站立时的疼痛程度，静卧时VAS评分≥30分为发生术后疼痛。计算异丙酚注射痛预测术后疼痛程度的灵敏度和特异度。结果异丙酚注射痛发生率为66％，VRS评分与术后静卧以及活动时VAS评分呈正相关（r=0．561，P〈0．01；r=0．608，P〈0．01）。异丙酚注射痛预测术后疼痛的灵敏度为96％，特异度为52％。结论术前异丙酚注射痛是预测人工流产术后患者疼痛程度的可靠指标。
Objective To investigate the accuracy of predicting acute postoperative pain by assessment of intravenous propofol injection-induced pain. Methods Seventy-one ASA I or II patients aged 20-40 yr scheduled for induced abortion operation were enrolled in this study. The patients were unpremedicated. ECG, HR, BP and SpO2 were continuously monitored before and during anesthesia. Anesthesia was induced with 2 mg/kg propefol. A third of the induction dose was injected via a dorsal hand vein. Pain induced by iv propofol injection was assessed with verbal rating scale （VRS） （0 = no pain, 3 = severe pain）. Postoperative abdominal pain was assessed with visual analog scale （VAS） （0 = no pain, 100 = most severe pain） at 20 rain after operation. Results The propofol injection pain occurred in 66% of patients. Postoperative VAS scores at rest and during activity and intravenous propofol injection-induced pain were significandy correlated （r = 0.561, P 〈0.01; r = 0.（308, P 〈0.01）. The sensitivity and specificity of iv propofol injection-induced pain （ VRS 〉 1 ） in predicting clinically significant acute postoperative pain （VAS 〉 30） were 96 % and 52 % respectively. Conclusion Preoperative iv propofol injectioninduced pain is a reliable factor in predicting acute postoperative pain and is useful in identifying those women who will experience greater pain after operation.
