Abstract:
Objective:To compare the hemodynamic responses to orotracheal intubation between TruviewTM EVO2 optic laryngoscope and Macintosh direct laryngoscope.Methods: Eighty adult patients(ASA physical status Ⅰ-Ⅱ,aged 18-65 years) scheduled for elective surgery under general anesthesia requiring orotracheal intubation were randomly divided into 2 groups(n=40 each):T group and M group.After standard intravenous anesthetic induction,orotracheal intubation was performed with TruviewTM EVO2 optic laryngoscope or Macintosh direct laryngoscope.Non-invasive heart rate(HR),systolic blood pressure(SBP),diastolic blood pressure(DBP),mean arterial pressure(MAP) and SpO2 were recorded before(T0) and after anesthetic induction(T1),at intubation(T2),1 minutes(T3),3 minutes(T4) and 5 minute after intubation(T5).The laryngeal exposure period and intubation period were also recorded.Statistical analysis was performed using the Statistical Package for Social Sciences(SPSS) Version 13.0.Results: Except for HR at intubation(T2),there was no significant difference in the hemodynamic data at any other time points between the two groups.There was no significant difference in the laryngeal exposure period between the two groups.The intubation time in the T group was significantly longer than that in the M group(P
