Abstract

Introduction and Aims: Currently wide arrays of video laryngoscopes are available to facilitate laryngoscopy and endotracheal intubation in routine and difficult airway patients, intensive care units (ICU) and emergency settings. This study is undertaken to compare the efficacy of C-MAC and King Vision video laryngoscope for easy laryngoscopy and endotracheal intubation in patients with no predictors of difficult airway.
Materials and Methods: 60 adult patients undergoing elective surgery were randomly allocated into 2 groups for intubation using either King Vision laryngoscope (KVL group) or C-MAC video laryngoscope (C-MAC group). The parameters recorded were need for external laryngeal manipulation, percentage of glottis opening (POGO score), Cormack Lehane grading, number of attempts and time taken for successful endotracheal intubation and the airway morbidity. Systolic, diastolic, mean blood pressure and heart rate were measured preoperatively and at 1 and 2 min following endotracheal intubation in both the groups. The obtained data were analysed using chi-square test and Student’s t-test using SPSS software.
Results: The use of Kings Vision laryngoscope or CMAC video laryngoscope did not differ significantly with respect to good laryngoscopy and intubating conditions. But airway morbidity was significantly lower in the KVL group (10%) when compared with the C-MAC group (40%) p<0>
Conclusions: The use of C-MAC or KVL provided excellent laryngoscopy and intubating conditions except for the airway morbidity and haemodynamic stability which were better with the use of KVL.
