Endotracheal intubation is commonly performed using direct laryngoscope. Video laryngoscope is a newer device for intubation and is considered to be more effective but time consuming than direct laryngoscopy. After the approval of institutional ethical committee, 100 patients were randomized for intubation by direct laryngoscopy (DL) and video laryngoscopy (VL), 50 in each. The following parameters were compared, time for intubation, visualisation of glottis by Cormack-Lehane (CL) grading, optimization manoeuvres and number of attempts. In DL group 14 and 36 patients had Cormack-Lehane grade I and II, in VL group 36 and 14 patients had Cormack-Lehane grade I and II (p value=0.000011). Head positioning was required in 50(100%) in DL group none in VL group (p value=0). Number of attempts were one in both groups. To conclude video laryngoscopy provided better visualisation of glottis and required lesser optimization manoeuvre but the time taken for intubation was more than direct laryngoscope. |
