Objective To observe the safety and efficacy of BlockBuster intubating laryngeal mask used in urologic day surgery.Methods Forty-two patients,38 males,4 females,aged 65-83 years,falling into ASA Ⅰ-Ⅲ,undergoing urologic day surgery were randomized to two groups:BlockBuster intubating laryngeal mask group (group B,n = 21 )and Proseal laryngeal mask group (group P,n =21).After anesthesia being induced,the patients were inserted BlockBuster intubating laryngeal mask or Proseal laryngeal mask accroding to body weight.The success rate of intubation, PET CO 2 and Ppeak at fifteen minutes after intubation,laryngeal mask exchange rate and side effects such as aspiration and backflow,post-intubation trachyphonia and sore throat were also recorded. Results The success rate of intubation in group B was significantly higher than that in group P(P <0.05).Laryngeal mask exchange rate in group B was lower than that in group P significantly (P <0.05).Ppeak at fifteen minutes after intubation of group B was significantly lower than that in group P and post-intubation trachyphonia in group B was also significantly lower than that in group P(P <0.05).Conclusion Compared with Proseal laryngeal mask,BlockBuster intubating laryngeal mask has some advantages in providing better hyperlarynx ventilation and increasing green channel to intu-bation,reducing aspiration risk and post-intubation trachyphonia,hence BlockBuster intubating laryn-geal mask can enhance the quality of resuscitation to patients undergoing urologic day surgery.%目的：观察 BlockBuster 喉罩用于泌尿外科日间手术的临床效果。方法选择泌尿外科日间手术患者42例,男38例,女4例,年龄65~83岁,ASA Ⅰ~Ⅲ级,随机分为 BlockBuster 喉罩组(B 组)和 Proseal 喉罩组(P 组),每组21例。麻醉诱导后根据患者体重选择适当型号的喉罩,B 组置入 BlockBuster 喉罩,P 组置入 Proseal 喉罩；记录两组喉罩一次置入成功率、喉罩置入后15 min PET CO 2和 Ppeak、经喉罩插管次数或喉罩换管次数、胃反流误吸和拔出喉罩后声嘶、咽痛等并发症的发生情况。结果 B 组喉罩一次置入成功率明显高于 P 组,插管或换管率明显低于 P 组(P <0.05)；B 组喉罩置入后15 min Ppeak 明显低于 P 组(P <0.05)；B 组声嘶发生率明显低于 P 组(P <0.05)。结论与 Proseal 喉罩比较,BlockBuster 喉罩在泌尿外科日间手术中可提供良好的声门上气道管理,同时增加声门下应急气管插管通道,反流误吸发生风险小且术后声嘶、咽痛等并发症少,有效提高泌尿外科日间手术术后患者恢复质量。
