ABSTRACT
Background:
Two-handed mask ventilation techniques are often used in cases of difficult mask ventilation scenarios. A comparison of two methods of two-handed techniques in terms of tidal volume was undertaken in the context of the obese population. Aims andObjectives:
To determine and compare the effectiveness of mask ventilation in obese Indian adult subjects by using either the C-E technique or the V-E technique after induction of general anaesthesia. Material andMethods:
This was a randomised interventional study conducted on eighty obese patients. They were randomized into Group A ventilated with C-E technique and Group B with V-E technique. Expired tidal volume (VTe), Peak inspiratory pressure (PIP), SpO2, EtCO2 and vital signs were noted.Results:
The BMI and hemodynamic parameters were comparable between the two groups. The expired tidal volume of 702 ± 77 mL with the V-E technique was significantly more than the C-E technique, which was 492 ± 71 mL. The ventilatory failure rate with the C-E technique was 15% and 0% with the V-E technique. There was no significant difference between the peak airway pressures for the two techniques 20.3 ± 1.5 mm H2O for Group A and 20.5 ± 1.2 mm H2O for Group B.Conclusions:
Mask ventilation with the two-handed V-E technique is associated with better tidal volumes and reduced failure rates in the obese population. So the V-E technique should be attempted first as a rescue measure in obese adult patients if the return of spontaneous breathing and tracheal intubation is impossible.
