Abstract:
Objective This study was to investigate the effect of using laryngeal mask airway (LMA)as a transition method after double lumen endotracheal anesthesia on the stress response dur-ing the extubation period.Methods Ninety patient underwent general anesthesia with double lumen endotracheal intubation were randomly divided into 3 groups:group A,B and C (n=30).Patients in group A were extubated directly after surgery.The double lumen endotracheal tube were changed to single lumen endotracheal tube under deep anesthesia in group B patients,while the double lumen en-dotracheal tube were changed to LMA in group C.MAP,HR and rate pressure product (RPP)at the end of surgery (T0 ),1 minute before extubating the endotracheal tube (laryngeal mask)(T1 ),1 mi-nutes (T2 ),5 minutes after extubating (T3 )were recorded.The reaction of extubation,such as buc-king or restlessness,was also observed.Results Compared with T0 ,the MAP,HR,and RPP were significantly increased in groups A and B at T1-T3 (P <0.05 ).Compared with group A,the MAP, HR,RPP were significantly decreased in groups B and C at T1-T3 (P <0.05 ).The number of buc-king and restlessness in group C were lower than that in group A and group B (P < 0.05 ). Conclusion The use of laryngeal mask during the transition period in double lumen endotracheal anes-thesia to can reduce hemodynamic fluctuations and stress reaction during the extubation.
