帝视观察用内窥镜辅助喉罩置入的临床效果

Clinical efficacy of laryngeal mask airway placement assisted by disposcope endoscope

目的探讨帝视观察用内窥镜引导喉罩置入的效果,为临床麻醉气道管理提供依据。方法选择2022年3月至2024年3月在揭阳市人民医院行喉罩置入全身麻醉患者60例,采用随机数字表将纳入研究患者分为观察组和对照组,每组30例。观察组使用帝视观察用内窥镜辅助喉罩置入,对照组使用传统徒手喉罩置入法。记录两组患者喉罩置入成功总时间(喉罩进入口腔到判定喉罩置入成功)、喉罩首次置入成功率、气道峰压、口咽漏气压以及喉罩置入损伤并发症发生情况,包括麻醉恢复室拔除喉罩后喉罩表面有无血迹、术后24 h内咽痛发生率。结果与对照组比较,观察组喉罩置入成功总时间明显缩短(P<0.001),喉罩首次置入成功率明显升高(P<0.05),两组喉罩型号比较差异无统计学意义(P>0.05);与对照组比较,观察组气道峰压明显降低(P<0.001),口咽漏气压明显升高(P<0.001);两组喉罩表面有血迹、术后24 h内咽痛发生率比较差异无统计学意义(P>0.05)。结论帝视观察用内窥镜引导喉罩置入,可以提高喉罩首次置入成功率,缩短喉罩置入成功总时间,降低气道峰压,升高口咽漏气压,有较高安全性,值得推广。

Objective To explore the efficacy of laryngeal mask airway placement assisted by disposcope endoscope,so as to provide basis for airway management in clinical anesthesia.Methods A total of 60 patients who underwent general anesthesia with laryngeal mask insertion at Jieyang People's Hospital from March 2022 to March 2024 were selected.They were randomly divided into observation group and control group,with 30 cases in each group.The observation group were given laryngeal mask airway placement assisted by disposcope endoscope,while the control group were given traditional manual laryngeal mask airway placement.And then,the total time of successful laryngeal mask insertion(from the laryngeal mask entering the oral cavity to the judgment of successful laryngeal mask placement),the first-time success rate of laryngeal mask insertion,peak airway pressure,oropharyngeal leak pressure,and the occurrence of complications due to laryngeal mask insertion injuries such as the presence of blood on the mask surface after removal in the recovery room and the incidence of sore throat within 24 hours after surgery were recorded between the two groups.Results Compared with the control group,the total time for successful insertion of laryngeal mask in the observation group was significantly shortened(P<0.001),the success rate of first-time insertion of laryngeal mask was significantly increased(P<0.05),and there was no statistically significant difference in the comparison of laryngeal mask models between the two groups(P>0.05).Compared with the control group,the observation group showed a significant decrease in peak airway pressure(P<0.001)and a significant increase in oropharyngeal leak pressure(P<0.001).There was no statistically significant difference in the presence of blood on the mask surface and the incidence of sore throat within 24 hours after surgery between the two groups(P>0.05).Conclusion Laryngeal mask airway placement assisted by disposcope endoscope can improve the success rate of first-time insertion,reduce the total time for successful placement,lower peak airway pressure,and increase oropharyngeal leak pressure,which has high safety and is worth promoting.
