Immediate Complications Related to Anesthesia in Patients Undergoing Uvulopalatopharyngoplasty for Obstructive Sleep Apnea

The objective of this retrospective chart review was to “analyze and assess the perioperative risks and complications in patients receiving general anesthesia undergoing surgery for obstructive sleep apnea. Thirty-two patients were reviewed with no severe adverse events such as reintubation, prolonged intubation, or postoperative pulmonary edema. Patients who were difficult to intubate or required nasal/oral airways failed to show any adverse outcomes”.

Management Plan to Reduce Risks in Perioperative Care of Patients with Obstructive Sleep Apnoea Averts the Need for Presurgical Polysomnography

There was no significant increase in postoperative complications in patients managed on the OSA risk management protocol. With this protocol, it is clinically safe to proceed with elective surgery without delay for formal polysomnography confirmation.

Obstructive Sleep Apnea and Oxygen Therapy: A Systematic Review of the Literature and Meta-Analysis

This review shows that O2 therapy significantly improves oxygen saturation in patients with OSA. However, it may also increase the duration of apnea-hypopnea events.

Obstructive Sleep Apnea Screening and Postoperative Mortality in a Large Surgical Cohort

Neither a prior diagnosis of OSA nor a positive screen for OSA risk was associated with increased 30-day or one-year postoperative mortality. Differences in 1 year postoperative mortality were noted with three screening tools.
