Abstract:
Objective To compare the hemodynamic responses to orotracheal intubation with GlideScope video laryngoscope (GSVL), Macintosh laryngoscope (MDLS) and fiberoptic bronchoscope (FOB) .Methods Sixty ASAⅠorⅡpatients (21 male, 39 female) aged 18-50 yrs weighing 45-90 kg scheduled for elective plastic surgery under general anesthesia with tracheal intubation and mechanical ventilation were randomly divided into 3 groups ( n = 20 each): GSVL group; MDLS group and FOB group. The patients were premedicated with intramuscular scopolamine 0.3 mg. Anesthesia was induced with midazolam 0.05 mg?kg-1 , fentanyl 2?g?kg-1 , propofol 2 mg?kg-1 and vecuronium 0.1 mg?kg-1 and maintained with 1% isoflurane and 60% N2O-40% O2 . Orotracheal intubation was performed at 2 min after intravenous vecuronium. Noninvasive BP and HR were recorded before and after induction of anesthesia, during tracheal intubation and at 1, 2, 3, 4, 5 min after tracheal intubation was completed. The HR and SBP product (RPP) was calculated. Results The intubation time was significantly longer in FOB group than in MDLS group (P
