The effects of dezocine preemptive analgesia on cardiorespiratory and recovery time of painless induced abortion

Objective:To investigate the effects of dezocine preemptive analgesia on cardiorespiratory and recovery time of painless induced abortion with propofol.Methods:Sixty cases with painless induced abortion were randomly divided into group A,B and C.Group A,B and C were injected the same volume normal saline,fentanyl(1 g/kg) and dezocine(0.05 mg/kg) at the time of 5 minutes before sterilizing respectively and 2 mg/kg of propofol were injected after sterilizing.Operation began after patients consciousness disappear,and 20-40 mg of propofol were added as needed.The data of basic value(T1),after anesthesia(T2),surgery(T3) and after surgery(T4),the operation and awakening time,the dosage of propofol and the grade of anesthesia effect were mesured.Results:The HR in group C postoperation were significantly lower that of preoperation(P0.05),but without further treatment.At T2,the values of SpO2 in group B were significantly lower than that in other two group(P0.01).The propofol consumption in group A were maximum,the recovery time in group C were the shortest and the anesthetic effects of group A were worse than that of group B and C(P0.05).Conclusions:Compared with the effects of alone propofol,the application of dezocine combined with in painless induced abortion is safety and effect,which is worthy to be popularized.
