目的：研究苯丙哌林在纤维支气管镜检查（纤支镜检查）中的作用。方法：纤支镜检查病人９０例，年龄３８±ｓ９ａ，随机分成３组，每组３０例。一组于术前０．５ｈ口服苯丙哌林４０ｍｇ，一组于术前０．５ｈ口服可待因３０ｍｇ，一组不服任何止咳药物。观察操作时间，术中２％利多卡因溶液用量，病人对操作的耐受性。结果：３组操作时间分别为８．２±１．３ｍｉｎ、８．３±１．３ｍｉｎ和１５．３±２．４ｍｉｎ，术中３组２％利多卡因液用量为４．５±１．４ｍＬ，４．６±１．３ｍＬ和７．６±１．９ｍＬ，用药组与不服药组有显著差异（Ｐ＜０．０１）。结论：苯丙哌林在纤支镜检查中具有与可待因类似的辅助作用，可缩短操作时间、减少利多卡因用量，但无可待因缺点。
AIM: To investigate the role of benproperine in bronchoscopy (bronchoscopy). Methods: Ninety patients with bronchofiberscopy, age 38 ± s9a, were randomly divided into three groups of 30 cases. A group of benproperine 40mg orally preoperative 0.5h, a group of 0.5h preoperative oral codeine 30mg, a group of any cough medication. Observation of operation time, intraoperative 2% lidocaine solution dosage, the patient’s tolerance to the operation. Results: The operation time of the three groups were 8.2 ± 1.3min, 8.3 ± 1.3min and 15.3 ± 2.4min respectively. The intraoperative 3% lidocaine 2% was 4.5 ± 1. 4mL, 4.6 ± 1.3mL and 7.6 ± 1.9mL, there was a significant difference between the medication group and the non-medication group (P <0.01). CONCLUSIONS: Benproperine has similar auxiliary effects with codeine in bronchoscopy, which can shorten the operation time and reduce the dosage of lidocaine, but there is no disadvantage of codeine.
