Abstract
Postoperative pulmonary complications are a major contributor of morbidity and mortality worldwide after surgery. Postoperative pulmonary problems happen as frequently as or more frequently than cardiac complications.
Upper abdominal incisions have traditionally been thought to be more hazardous to PPCs than lower incisions. The fundamental operating mechanism is thought to be more extensive reflex inhibition of diaphragmatic function following upper abdominal procedures.
High flow nasal cannula is a newly designed device that permits administration of gas flow up to 60L/min using silicone nasal cannula under ideal conditions of administered gas temperature and humidity.
The use of HFNC improves oxygenation by a variety of processes, including reduced dilution of supplied oxygen with ambient air, washout of dead space, increased tidal volume, and the creation of continuous positive airway pressure.
Due to the active humidification of the supplied gas, the approach may also improve mucociliary transport and promote patient physical exertion capability and satisfaction.
The purpose of this research was to assess the effects of HFNC and simple face mask oxygen therapy on postoperative pulmonary complications, the requirement for escalation of respiratory support, intensive care unit length of stay, and hospital length of stay after major elective upper abdomen operations.
