Abstract:
ObjectiveTo observe the different mode of administration of lidocaine on hemodynamic effects during self-retaining laryngoscope.Methods75 adult patients,underwent selective operations of removal and biopsy of the vocal polype,epiglottis or laryngeal tumor via self-retaining laryngoscope under general anesthesia,were randomly divided into three groups,with 25 cases for each.Group Ⅰ was the control group; Group Ⅱ was the throat spraying group;Group Ⅲ was the intravenous drug group.The incidence of irritating cough and the changes of mean arterial pressure(MAP) and hear rate(HR) were observed during operations.ResultsThe incidence of irritating cough in group Ⅱ was lower than in group Ⅰ and group Ⅲ ( all P < 0.05 ).MAP,HR in group Ⅱ was also lower than that in group Ⅰ and Ⅲ during extubation( all P <0.05).However there were no significant differences on MAP,HR between group Ⅰ and group Ⅲ during extubation( all P > 0.05 ).ConclusionLidocaine spraying on larynx could alleviate irritating cough and had significant preventive effect on cardiovascular response,and the effect in this method was superior to intravenous injection.
