| Popis: | Context: We hypothesized that reduced oropharyngolaryngeal stimulation with video laryngoscopes would attenuate hemodynamic response to laryngoscopy and intubation. Aim: Comparison of hemodynamic response to laryngoscopy and intubation with video laryngoscopes and Macintosh (MC) laryngoscope. Setting and Design: Superspecialty tertiary care public hospital; prospective, randomized control study. Methods: Sixty adult patients undergoing elective coronary artery bypass grafting (CABG) were randomly allocated to three groups of 20 each: MC, McGrath (MG), and Truview (TV). Hemodynamic parameters were serially recorded before and after intubation. Laryngoscopic grade, laryngoscopy, and tracheal intubation time, ST segment changes, and intra-/post-operative complications were also recorded and compared between groups. Statistical Analysis: SPSS version 17 was used, and appropriate tests applied. P < 0.05 was considered significant. Results: Heart rate and diastolic arterial pressure increased at 0 and 1 min of intubation in all the three groups (P < 0.05) while mean arterial pressure increased at 0 min in the MG and TV groups and at 1 min in all three groups (P < 0.05). A significant increase in systolic arterial pressure was only observed in TV group at 1 min (P < 0.05). These hemodynamic parameters returned to baseline by 3 min of intubation in all the groups. The intergroup comparisons of all hemodynamic parameters were not significant at any time of observation. Highest intubation difficulty score was observed with MC (2.16 ± 1.86) as compared with MG (0.55 ± 0.88) and TV (0.42 ± 0.83) groups (P = 0.003 and P = 0.001, respectively). However, duration of laryngoscopy and intubation was significantly less in MC (36.68 ± 16.15 s) as compared with MG (75.25 ± 30.94 s) and TV (60.47 ± 27.45 s) groups (P = 0.000 and 0.003, respectively). Conclusions: Video laryngoscopes did not demonstrate any advantage in terms of hemodynamic response in patients with normal airway undergoing CABG. |
