【摘要】 目的:评估可视喉罩CTrach作为一种新型气管内插管途径在全身麻醉(全麻)诱导中气道管理的应用价值。方法:选择ASAⅠ～Ⅱ级全麻需行经口气管内插管的择期手术患者112例,随机分为可视喉罩气管插管组(CT组)和传统直接喉镜气管插管组(DL组),两组均采用常规静脉麻醉诱导。记录两种方式引导气管导管首次插入的成功率、总的成功率、插管时间以及插管后咽喉疼痛、声音嘶哑等不良反应;并分别记录两组患者行气管内插管各时间点的血压(BP)和心率(HR)。结果:两组首次插管成功率、总的成功率、插管时间、术后咽喉疼痛、声音嘶哑的发生率,CT组为87.7%、94.7%、(189.5±33.2)s和8.0%;DL组为90.9%、96.4%、(32.4±9.7)s和38.0%。CT组的平均气管插管时间较DL组明显延长(P<0.05),术后咽喉疼痛、声音嘶哑发生率明显少(P<0.05);气管插管时两组患者中BP和HR较麻醉诱导后均明显升高(P<0.05),CT组和DL组间BP和HR无明显差异(P>0.05)。结论:CTrach喉罩可视下行气管内插管成功率高,操作简单,损伤小,是解决临床困难气道插管的有效方法之一。更多还原

【Abstract】 Objective: To evaluate the effectivity of the fibreopic intubating laryngeal mask airway CTrach which offers a new approach for endotracheal intubation in airway management undergoing general anesthesia induction.Methods: 112 patients of ASA physical status Ⅰor Ⅱ,who required general anesthesia induction with endotracheal intubation for elective surgery,were randomly allocated to either the LMA CTrach-guided endotracheal intubation(CT) group or conventional direct laryngoscope-guided endotracheal intubation(DL) group.After a standard intravenous anesthetic induction,the endotracheal intubation was performed.The first attempt successful rate,the totally successful rate and the time for tracheal intubation were recorded.All patients were followed up postoperatively for adverse effects like sorethroat or hoarseness.And the changes of noninvasive blood pressures(BP) and heart rates(HR) in period of tracheal intubation with two methods were also recorded.Results: The first insertion successful rate,the totally insertion successful rate,intubation time,postoperative adverse effects,CT group was 87.7%,94.7%,(189.5±33.2)s and 8.0%;DL group was 90.9%,96.4%,(32.4±9.7)s and 38.0%.The mean intubation time was longer in the CT group than in the DL group(P<0.05).And adverse effects like sorethroat or hoarseness were lower in the CT group than in the DL group(P <0.05).BP and HR were significantly increased after intubation compared with their postinduction values in two groups(P<0.05),but there were no significant difference between CT group and DL group(P>0.05).Conclusion: The LMA CTrach provides a high success rate for tracheal intubation with fibreoptic components,and has features of simple operation and little damnification.It is an effective way to resolve tracheal intubation with difficult airways.更多还原
