Study on Anesthesia Method Improvement for Branchofiberoscope / 中国药房

ABSTRACT

OBJECTIVE:To compare anesthesia effects of 3 anesthesia methods,to investigate anesthesia improvement method for bronch fiber oscope. METHODS:315 patients undergoing bronch fiber oscope were randomly divided into group A(106 cas-es),group B(104 cases)and group C(105 cases). Group A was treated with traditional bronch fiber oscope lidocaine atomization local anesthesia,group B was treated with modified bronch fiber oscope pethidine combined with lidocaine atomization local anes-thesia and group C was treated with three-limb tube connected with laryngeal mask and target-controlled propofol and remifentanil general anesthesia. SaO2,SBP,DBP,heart rate,breathing rate,excellent anesthesia rate,compliance rate,the rate of bodymove-ment and choking,pain recalling rate were compared among 3 groups before and during examination,and ADR was observed. RE-SULTSCompared with before examination,SaO2 of group A was decreased significantly during examination,with statistical sig-nificance(P<0.05);that of group B and C had no obvious change before and during examination. Blood pressure,heart rate and breathing rate of 3 groups had no obvious change before and during examination. The excellent anesthesia rate and compliance rate of group A were significantly lower than those of group B and C,but the rate of bodymovement cough and pain recalling rate were significantly higher than group B and C,with statistical significantly(P<0.05). The excellent anesthesia rate and compliance rate of group B were significantly lower than those of group C,but the rate of bodymovement cough and pain recalling rate were signifi-cantly higher than group C,with statistical significance (P<0.05). No ADR was found in 3 groups. CONCLUSIONS:Modified bronchoscope atomization local anesthesia and modified painless bronchoscope are better than traditional bronch fiber oscope atomi-zation local anesthesia in anesthesia effect,safety,degree of comfort and acceptability. Modified bronchoscope atomization local an-esthesia was best but most expensive,so these methods can be chosen according to patient’s condition.
