Clinical Comparison Of Different Anesthesia Methods In Vocal Cord Polyps'surgery Through Suspension Laryngoscope

Objective: Through comparing the Clinical observation of vocal cord polyps surgery through suspension laryngoscope in different anesthesia methods,to study the advantage of non-muscle relaxant anesthesia in vocal cord polyps surgery through suspension laryngoscope.Methods: Forty American Society of Anesthesiologists (ASA) physical statusâ… orâ…¡patients scheduled for vocal cord polyp surgery through suspension laryngoscope were randomly divided into two groups, Group A and Group B (n=20 in each group). Subjects in Group A were given cis-atracurium 1.0 mg kg-1( 2â…¹ED95 ), and Group B were not given any muscle relaxant. To do the vocal cord polyp surgery through suspension laryngoscope under different anesthesia methods.HR and MAP at different time points,the indicators of intubation, operation time,recovery time about some indicators after surgery,OAA/S grade at different time point after surgery and surgeon satisfaction were recorded compared in each group.Results: Group B have shorter spontaneous breathing recovery time, waking time, extubation time and leaving operation room time than Group A ( P<0.05 ). Group B have longer intubation time than Group A ( P<0.05 ), but it has little clinical significance. There were not statistically significant in Cormack grade, intubation conditions, intubation times, operation time, OAA/S grade and surgeon satisfaction.Conclusion: Non-muscle relaxant anesthesia can provide similar surgeon satisfaction and ideal anesthetic effect for the vocal cord polyps surgery through suspension laryngoscope, benefit the patients in recovery after surgery, reduce the risk of muscle relaxant and accelerate the turnover rate of surgery.
