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.

Comparative Study[Study of the survival of elderly patients in intensive care units. Should they be admitted to these units?].
An important increase in health care costs has occurred lately, determined in part by the expenses of intensive care units. An important proportion of beds in these units are occupied by elders, with high costs and dubious results. ⋯ Older age was not associated with a higher mortality during intensive care unit stay. Prognosis is determined by the admission severity score and the number of concomitant chronic diseases.
