King Vision video laryngoscope versus Lightwand as an intubating device in adult patients with Mallampatti grade III and IV patients

Measurements and Main Results: Mean intubation time using King Vision video laryngoscope (19.50 ± 6.73 seconds was lower than the intubation time using Lightwand 25.40 ± 7.42 s, P = .00). The difference between number of attempts, success of intubation, numbers of adjustment maneuvers were comparable. There was a significant rise in heart rate within the groups from the pre-induction values. However inter group variations were similar. In addition, there was a significant rise in mean arterial pressure within the groups from the pre-induction values. Inter group variations show less increase in mean arterial pressure with Lightwand at immediate post intubation (P = .0234) and at 3 min and 5 min post intubation anesthesia.
