Brief Summary

Carbon dioxide insufflations of abdomen are integral part of laparoscopic operations in minimally invasive surgery era. It does cause splinting effect on diaphragm movement and set it high inside thoracic cavity too. In turn it will be associated with increase in peak and plateau airway pressure during positive pressure ventilation. Inverse ratio ventilation has been shown to improve lung compliance and restrict the peak and plateau airway pressure and should be useful as one of the lung protective ventilation method to improve respiratory outcome in laparoscopy surgery.

Outcome Measures

Primary Outcomes (1)

  • change in partial pressure of oxygen from baseline

    Investigators assume that in laparoscopic surgeries inverse ratio ventilation can be used to decrease the airway pressures

    upto 1 day postoperatively

Secondary Outcomes (1)

  • changes in pulmonary function tests from baseline

    upto 3 days postoperatively

Study Arms (2)

intervention group

EXPERIMENTAL

in this group of patients, inverse ratio ventilation is provided during general anaesthesia

Other: inverse ratio ventilation

control group

NO INTERVENTION

in this group of patients, conventional ventilation is provided during general anaesthesia

Interventions

during general anaesthesia in laparoscopic surgeries, this group of patients will receive inverse ratio ventilation with proper observation of hemodynamics
