to compare intubating conditions and hemodynamic changes between bonfils intubation fiberscope and macintosh laryngoscopy without administering neuromuscular blocking drugs (nmbds). methods: in this randomized controlled trial,80 male and female patients, scheduled for elective surgery, aged 15 to 60 years, asa class ii or i, non-obese, non smokers, without anticipated difficult intubation; wer...

background: there is evidence that electrocardiographic (ecg) changes occur during elective cesarean section in parturients. these changes, mostly in the form of st-segment depression, have been noted in either regional anesthesia or general anesthesia. we performed this study to compare hemodynamic variables and electrocardiographic changes suggestive of myocardial ischemia following administr...

background: to determine if the glidescope® videolaryngoscope (gvl) could attenuate the hemodynamic responses to orotracheal intubation compared with conventional macintosh laryngoscope. objectives: the aim of this relatively large randomized trial was to compare the hemodynamic stress responses during laryngoscopy and tracheal intubation using gvl versus mcl amongst healthy adult individuals r...
