Key result
Intubation via intubating laryngeal mask airway resulted in significantly lesser increases in mean heart rate, SBP, and DBP compared to Macintosh laryngoscope (p < 0.05).
Why the study?
The study was conducted to evaluate hemodynamic changes and side effects during endotracheal intubation comparing the Macintosh laryngoscope and intubating laryngeal mask airway.
Does endotracheal intubation through an intubating laryngeal mask airway reduce hemodynamic changes compared to a Macintosh laryngoscope in patients aged 18 to 60 years?

Does endotracheal intubation through an intubating laryngeal mask airway reduce hemodynamic changes compared to a Macintosh laryngoscope in patients aged 18 to 60 years?
p-value: p=<0.05
Intubating laryngeal mask airway is a viable alternative to direct laryngoscopy with a Macintosh blade, offering better hemodynamic stability during intubation.
Favors ILMA over Macintosh when blunting intubation hemodynamics matters; extends RCT evidence for device selection in elective adults.
Aim: To evaluate the hemodynamic changes and side effects during endotracheal intubation with Macintosh laryngoscope and intubating laryngeal mask airway. Materials and methods: A prospective, simple randomized, comparative study on 100 patients 18 years - 60 years of age, divided into two groups: Group A comprising intubation with Macintosh laryngoscope and Group B intubation through ILMA. Results: Total intubation time (in seconds) of group A was 24.38 + 3.26 seconds and of the group, B was 42.94 + 1.24 seconds. At 2,4 and 6, a higher rise in mean heart rate was noted in group A (p < 0.05). At 2,4,6 and 8 minutes difference in mean SBP and mean DBP of the two groups was statistically significant with a p - value of < 0.05 with a significant increase of mean SBP and mean DBP in patients of group A. The difference for all complications was not significant between the two groups. Conclusion: Intubation via intubating laryngeal mask airway can be done as an alternative to direct laryngoscopy using a Macintosh blade as intubation via intubating laryngeal mask airway has shown to have lesser hemodynamic changes.

Somika et al. (2022) reported an RCT. Intubating laryngeal mask airway (ILMA) vs. Macintosh laryngoscope was evaluated on Hemodynamic changes (mean heart rate, SBP, DBP) (p=<0.05). Intubation via intubating laryngeal mask airway resulted in significantly lesser increases in mean heart rate, SBP, and DBP compared to Macintosh laryngoscope (p < 0.05).
