Application of proseal laryngeal mask airway in the anesthesia of interventional therapy for thoracic aortic dissecting aneurysm

Objective To investigate the clinical application effect of proseal laryngeal mask on anesthesia of interventional therapy for thoracic aortic dissecting aneurysm.Methods Forty patients with thoracic aortic dissection aneurysm underwent endovascular stent graft repair,ASA Ⅱ ～ Ⅲ,were randomly divided into endotracheal intubation anesthesia group (group ET) and proseal laryngeal mask anesthesia group(group PLMA),with 20 cases in each group.During operation,the hemodynamics,pulse oxygen saturation (SpO2),drug dosage,recovery and extubation time,anesthesia related complications of patients were observed.Results At before intubation (T2),the SBP,MAP and HR of patients in group ET were significantly lower than those in group PLMA (P ＜ 0.05).At endotracheal intubation immediate (T3) and extubation immediate (T5) time,the SBP,MAP and HR of patients in group ET were significantly higher than those in group PLMA (P ＜ 0.05).Anesthetics dosage of anesthesia induction and anesthetics dosage of maintenance of anesthesia in group PLMA were fewer than those in group ET (P ＜0.05).Sodium nitroprusside dosage of patients in group PLMA were significantly less than that in group ET(P ＜ 0.05).The patients in group PLMA awaked more rapidly (P ＜ 0.05).During intraoperative and postoperative periods,complications associated with anesthesia had not occurre in the two groups.Conclusions The effect of proseal laryngeal mask anesthesia on endovascular stent graft repair of thoracic aortic dissecting aneurysm is good,the anesthetic controllability increases greatly,the anesthetic risk is lowered.Compared with traditional endotracheal intubation anesthesia,proseal laryngeal mask anesthesia has a lot of advantages,is worthy to be popularized in clinics.
