: Difficult tracheal intubation still contributes significantly to anaesthesia related morbidity and mortality. Poor visualisation of laryngeal structures and multiple attempts at intubation are the leading causes with the conventional laryngoscopes. Though the recently introduced video assisted devices have significantly improved the ease of intubation by their superior laryngeal visualisation, the duration of intubation may vary. Here we compared the ease of tracheal intubation using Macintosh conventional direct laryngoscope (DL) and C- MAC videolaryngoscope (VL) in patients with expected difficult tracheal intubation. A total of 140 patients undergoing elective surgery under general anaesthesia with Modified Mallampati Class 3 and 4 found during the preoperative airway assessment were equally recruited to either of the groups. We compared the duration of tracheal intubation, visualisation of the laryngeal inlet, additional optimising manoeuvres required, and number of attempts at intubation and incidence of oral trauma assessed at extubation between the two groups.: Analysis done using Statistical Packages for the Social Sciences (SPSS) software; Windows version 11.0 (SPSS Inc., Chicago, IL, USA). Intubation time was significantly longer in patients with VL than DL (P 0.0001) whereas visualisation of laryngeal inlet was significantly better with VL (P 0.001). Additional optimising manoeuvres (P 0.001) and incidence of oral trauma (P 0.012) were significantly less with VL whereas intubation attempts were found comparable (P 0.586).: Though VL provided significantly better laryngeal view with less need for optimising manoeuvres and less oral trauma compared to DL, the duration of intubation was significantly more with the former.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
