Methods
orotracheal intubation
HEART, COMPLICATIONS
we conducted a prospective randomized clinical trial that included elderly patients proposed for a scheduled surgery under general anesthesia with orotracheal intubation and divided into 2 groups: patients who were intubated using the McGrath® (group V) and patients who were intubated using the Macintosh direct laryngoscope (group M). Heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial blood pressure (MAP), were recorded before induction of anesthesia (baseline), and at 1 min, 3 min, and 5 min after intubation. Our outcomes were the increase of SBP (∆ SBP), MAP (∆ MAP), and HR (∆ HR) between the two groups, during the 5 minutes following the start of the orotracheal intubation, intubation time and the incidence of its related complications.
