Influence of transient asphyxia oxygenation on early prognosis of patients with palmar hyperhidrosis in thoracoscopic sympathectomy
Objective To explore the influence of transient asphyxia oxygenation on early prognosis of the patients with palmar hyperhidrosis in thoracoscopic sympathectomy.Methods A total of 150 patients with palmar hyperhidrosis were randomly divided into two groups.All the patients were given laryngeal mask intubation general anesthesia.Group A(71 cases)were given transient asphyxia oxygenation during operation,and group B(79 cases)underwent spontaneous breathing during operation.HR,MAP,SpO2 and venous blood gas indicators of the two groups were compared before anesthesia(T1),before skin incision(T2),at the end of surgery(T3)and after leaving operation room(T4).The occurrence of perioperative adverse reactions and postoperative recovery were recorded.Results Compared with T1,HR and MAP were decreased and PaO2 was increased at T2-T4(P＜0.01),SpO2 and pH were increased and PaCO2 were decreased at T2(P＜0.05 or P＜0.01),and pH was decreased and PaCO2,base excess and HCO3-were increased at T3 and T4 in two groups(P＜0.01).PaCO2 at T4 was decreased in group A than that in group B(P＜0.05).There were no significant differences in the incidence of adverse reactions,the time of laryngeal mask removal and postoperative hospital stay between the two groups(P＞0.05).Conclusion The transient asphyxia oxygenation during thoracoscopic sympathectomy does not cause carbon dioxide accumulation,and has no effect on the early prognosis of patients with palmar hyperhidrosis,which is safe and feasible.
