Randomized Controlled Trial Clinical Trial[Nocturnal hypoxemia after abdominal surgery: associated factors and usefulness of oxygen therapy].
Postoperative nocturnal hypoxemia (PONH) is a main factor in the genesis of respiratory, cardiac and neurologic complications after surgery. ⋯ PONH is a common event in patients older than 40 years scheduled for open or laparoscopic abdominal surgery, and develops more frequently in those with preoperative nocturnal hypoxemia and greater ventilatory impairment. PONH can be prevented, most of the time, with oxygen administration.
