Abstract:
Objective To compare the clinical effect of nasal intubation with domestic video intubationscope and Macintosh direct laryngoscope. Methods One hundred patients scheduled for oro-maxillo-facial operation, American Society of Anesthesiologists (ASA) grade I or II, aged 19 ~ 67 years, were randomly divided into the domestic video intubationscope group (group V) and the Macintosh direct laryngoscope group (group M), with 50 cases in each group. Nasal intubation was respectively performed with domestic video intubationscope (Group V) and Macintosh direct laryngoscope (group M). Cormark-Lehane grade (C-L classification), tracheal intubation time, first-time intubation success rate and tracheal intubation complications were recorded.Mean arterial pressure (MAP) and heart rate (HR) of before induction of anesthesia (T0), after induction of anesthesia (T1), at glottic exposure (T2), at intubation (T3), 1 min after intubation (T4) and 3 min after intubation (T5) were recorded. Results C-L classification in group V was significantly lower than that in group M (P < 0.05), intubation time in group V was significantly shorter than that in group M (P < 0.05), first-time intubation success rate in group V was significantly higher than that in group M (P < 0.05). Compared with T1, MAP was significantly higher at T3~ T4and HR was significantly faster at T3in group V, MAP was significantly higher at T2~ T4and HR was significantly faster at T2~ T3in group M (P < 0.05). Compared with group M, MAP and HR in group V were significantly lower at T2~ T4 (P < 0.05). The incidence of tracheal intubation complications in group V was significantly lower than that in group M (P < 0.05). Conclusions Compared with Macintosh direct laryngoscope,domestic video intubationscope in nasal intubation is better in glottic exposure,it could shorten tracheal intubation time ,increase first-time intubation success rate, maintain stable hemodynamics, has fewer tracheal intubation complications and is worthy of clinical application.
