ABSTRACT
Background@#Nasotracheal intubation (NTI) is commonly performed in oromaxillofacial surgeries. We did this metanalysis to ascertain whether use of video laryngoscopy (VL) provided better NTI characteristics as compared to direct laryngoscopy (DL) in patients undergoing oromaxillofacial surgeries. @*Methods@#We performed a systematic search to identify randomized controlled trials comparing VL with DL for NTI in adults undergoing elective oromaxillofacial surgery. The primary outcome was time to intubation. Secondary outcomes included the first attempt success, overall success, incidence of nasal bleeding, Cormack and Lehane grade, and maneuvers required. @*Results@#Of the 456 studies identified following a systematic search, 10 were included. Meta-analysis showed a significantly lower time to tracheal intubation favoring VL (mean difference: –9.04, 95% CI [–12.71, –5.36], P < 0.001; I2 = 59%). VL was also associated with a greater first attempt success (relative risk [RR]: 1.10, 95% CI [1.04, 1.16], P = 0.001). Maneuvers to facilitate intubation were less with VL (RR: 0.22, 95% CI [0.10, 0.51], P < 0.001). There was no difference in overall intubation success (RR: 1.04, 95% CI [0.98, 1.10], P = 0.17). The incidence of bleeding did not differ between the DL and VL groups (RR: 0.59, 95% CI [0.32, 1.08], P = 0.09). @*Conclusions@#Evidence as per this meta-analysis suggests VL leads to a shorter time to NTI, a greater first attempt success rate, and reduced need for maneuvers when compared to DL. The present study supports use of VL as a first line device for NTI in oral-maxillofacial surgeries in experienced hands.

ABSTRACT
Electrical defibrillation is the most important therapy for patients in cardiac arrest. The audit was aimed to assess awareness among residents with respect to routine preuse checking of cardiac defibrillators. The audit was conducted at a multispeciality tertiary care referral and teaching center by means of a printed questionnaire from anaesthesiology residents. A database was prepared and responses were analyzed. Eighty resident doctors participated in the audit. Most [97.8%] of the residents were sure of the presence of a defibrillator in the operation room [OR]; 70% of postgraduates [PG]s were aware of the location of the defibrillator in the OR as compared to 83.7% of the senior resident [SRs]. Also, 32.1% residents routinely check the availability of a defibrillator. The working condition of the defibrillator was checked by 21.7% of the residents; 25.3% ensured delivery of the set charge. Further, 8.2% of residents ensured availability of both adult and paediatric paddles. About 27.8% of residents ensured the availability of appropriate conducting gel and 53.8% residents were of the opinion that the responsibility of checking the functioning and maintenance of the defibrillators lies with themselves. Some 22% thought that both doctors and technical staff should share the responsibility, while 19.5% opined that it should be the responsibility of the technical staff. All medical equipment is to be tested prior to initial use and periodically thereafter. An extensive, recurring training program, and continued attention to the training of clinical personnel is required to ensure that they are proficient in the operation and testing of specific defibrillator models in their work area. We conclude that apart from awareness of the use of the equipment we are using, its preuse testing is must. All resident doctors should be aware of the presence and adequate functioning of the defibrillator in their ORs and this audit reinforces the need for training of all resident doctors
