摘　　要：目的观察0．1％丁卡因表面麻醉用于正颌术后患者胃管置入过程中，对置管不适的效果和一次置管成功率的影响。方法将80例双颌接受正颌外科手术的患者采用随机数字表法分为对照组以及干预组，每组40例。两组均于术后第1天采用半卧位经鼻留置胃管，对照组用传统方法留置胃管，干预组置管前3min应用0．1％的丁卡因给予咽腔喷雾表面麻醉，分别测量置管时间和一次性置管成功率，并对置管不适情况进行评估。结果干预组置管时间显著短于对照组（2．7±0．8minVS4．2±1．1min），一次性置管率高于对照组（97．5％ vs 85．0％），置管疼痛不适程度明显减轻，差异均有统计学意义（t=2．892，X2=3．914，Z：2．660；P〈0．05）。结论胃管置管时应用0．1％丁卡因表面麻醉可有效减轻患者置管痛苦，提高了一次性置管成功率。Objective To evaluate the effects of oropharyngeal topical anesthesia with tetracaine spray （0.1% ） on the discomfort and success rate of insertion of stomach tube after orthognathic surgery.Methods Totals of 80 patients treated with bimaxillary orthognathic surgery were randomly assigned into control group （ n = 40） and test group （ n = 40）. Stomach tubes were inserted into stomachs of the patients with a semi- recumbent position through nasal at the day after surgery. Traditional methods of inserting stomach tubes were applied in control group, while patients in test group were given topical anesthesia with 0.1% tetracaine spray to oropharyngeal before stomach tubes inserted. The operating time and primary success rate of tube insertion were recorded. Intubation pain or discomfort was observed. Results The operating time of test group was significantly shorter than that of control group （2.7 4- 0.8 min vs 4.2±1.1 rain, t = 2. 892,P 〈 0.01 ）. Primary success rate of intubation of test group was significantly higher than that of control group （97.5% vs 85% , X2 = 3. 914 ,P 〈 0.05 ）. There was less pain or discomfort in the intubation process in test group （ Z = 2. 660, P 〈 0.01 ）. Conclusions Stomach tube insertion with 0.1% tetracaine spray topical anesthesia can alleviate pain, improve primary success rate of stomach tube insertion.
