扁桃体摘除术后24～48h疼痛较重,口服止痛药困难,直肠用药又不为人们所接受。非类固醇抗炎药物双氯高灭酸对疼痛有效,且不诱发出血。为了研究双氯高灭酸的止痛效果,以阿片全碱为对照,进行了双盲对比临床实验。50名患者,诱导麻醉后随机分为两组,A组23人肌注阿片全碱0.3mg/kg,B组27人肌注双氯高灭酸1mg/kg。于术后平均35min,3h,6h及19h肌注。分别评估 Tonsillectomy after 24 ~ 48h heavier pain, oral painkillers difficult, rectal medication is not acceptable. The non-steroidal anti-inflammatory drug diclofenac is effective in pain and does not induce bleeding. In order to study the analgesic effect of diclofenac, a double-blind comparative clinical trial was conducted with opium all base as a control. Fifty patients were randomly divided into two groups after induction of anesthesia. Group A received intramuscular injection of Opioid 0.3 mg / kg and Group B received intramuscular injection of diclofenac 1 mg / kg. After an average of 35min, 3h, 6h and 19h intramuscular injection.
