摘要

Self assembled video laryngoscope is a good alternative to commercial video laryngoscope, being cost effective. Intubation time is higher when best glottic view of laryngoscopy is used for intubation using this device. Partially restricted glottic view of laryngoscopy can significantly decrease the intubation time. Fifty patients of either sex aged 18 to 65 years were included. After induction of general anaesthesia, patients of Group I (n = 25) were intubated using best glottic view of laryngoscopy and patients of Group II (n = 25) were intubated using partially restricted glottic view of laryngoscopy. The primary objective was total intubation time. Secondary objectives were time for glottic visualisation, grade of glottic visualization, time for tube insertion after glottic visualization, first attempt intubation success, number of attempts for intubation and use of additional maneuvers. Continuous variables were compared using the independent sample t-test and categorical variables were compared using the Chi-square test. The mean total intubation time was 25.44 (standard deviation [SD]: 4.51) s in Group I and 20.64 (SD: 4.08) s in Group II (P = 0.001) (mean difference: 4.8 [95% CI: 2.35, 7.24]). Mean time for glottic visualisation was comparable. Grade of glottic visualization were significantly lower in group I (p = 0.001). Mean time for tube insertion after glottic visualisation was 13.16 (SD: 4.56) in Group I and 7.60 (SD: 1.87) in Group II (p = 0.001) (mean difference 5.56 [95% CI: 3.57, 7.54]). First attempt intubation success and number of attempts for intubation were comparable. Additional maneuvers (BURP and rotation of tube) were significantly more in group I (p = 0.001). Partially restricted glottic view of laryngoscopy significantly decreases the total intubation time using self assembled video laryngoscope.
