ObjectiveTo compare the variations of cardiovascular responses and vascular angiotensin II (AngII) in hypertensive patients during tracheal intubation with intubating laryngeal mask airway (ILMA) versus direct laryngoscope (DLS).MethodsA total of 120 hypertensive patients undergoing abdominal surgery were randomly divided into 2 groups, i.e.intubating laryngeal mask airway (Group I) and direct laryngoscope (Group D).Variations of invasive arterial blood pressure and angiotensin II were compared between two groups before and after intubation.ResultsThe variations of cardiovascular responses and vascular angiotensin II (AngII) during tracheal intubation used of ILMA (T4) and DLS (T4) in an instant, tracheal intubation were immediately accomplished in two groups (T5). The variations of group I were significantly lower than those of group D (P < 0.05). And statistical significance existed between two groups.ConclusionTracheal intubation with intubating laryngeal mask airway (ILMA) can significantly reduce violent cardiovascular reactions and avoid cardiovascular accidents.
