| Summary: | Introduction: Airway management is of paramount importance during general anaesthesia and in emergency. This randomized study was undertaken to assess and compare Block Buster laryngeal mask airway (LMA) versus McGrath video laryngoscope for orotracheal intubation in adults. Methodology: Sixty, ASA grade I-III patients aged 30-60 years for elective surgery requiring general anesthesia with orotracheal intubation were enrolled for this prospective randomized study. They were randomly allocated to two groups. Standard anesthesia technique was used for all patients. In group A (N 30), intubation was performed using Block Buster LMA and in group B (N 30), McGrath videolaryngoscope was used. Device insertion time, intubation time, first attempt success rate for endotracheal intubation, use of manouvers, ease of intubation, hemodynamic changes, and complications were recorded and compared between the two groups. Data were analyzed using SPSS statistical software version 21 and p value <0.05 was considered statistically significant. Results: The mean insertion time was significantly more in LMA group (21.13±8.18 seconds v/s 9.93 ± 8.90 seconds; p <0.001). The mean intubation time was more in Block Buster LMA group A(22.23 ± 14.6 seconds) than in McGrath videolaryngoscope group B (20.5 ± 14.32 seconds) but the difference was non-significant. First attempt success rate was also comparable between group A and group B (76.7% v/s 73.4%, p 1). The overall success rate was 100% for both the devices. Airway optimization manoeuvres were needed in 36.7% patients in LMA group and 33.4% of patients in videolaryngoscope group. Conclusion: Block Buster LMA is comparable to McGrath videolaryngoscope for orotracheal intubation in terms of first attempt success rate and ease of intubation with only few seconds more time taken for intubation with Block Buster LMA. |
