Under the Scope: Sleep Apnea and Complications

A new study in the journal Sleep and Breathing assessed whether obstructive sleep apnea (OSA) raises the risk of cardiorespiratory complications during endoscopic procedures.

The study was retrospective. Researchers identified patients who had undergone an endoscopic procedure under conscious sedation from January 2001 to May 2008. Each patient also took a sleep study in that period.

Patients composed four groups. The groups included 130 people with no OSA, 135 with mild OSA, 125 with moderate OSA, and 249 with severe OSA.

The patients were an average of 60.5 years of age. Ninety-three percent were male. Their mean body mass index was 33.7, indicating obesity.

Colonoscopies accounted for 68.5 percent of procedures. Upper endoscopies accounted for 20.2 percent. Combined procedures represented 11.3 percent.

The researchers tracked procedure complications.

Minor complications included problems like hypertension and oxygen desaturation.

Major complications included chest pain, respiratory distress, and cardiorespiratory arrest. Major problems required intervention.

Seven percent of patients had major complications and 19 percent had minor ones.

Importantly, complication rates did not significantly differ between the patients with and without OSA.

Results indicate that OSA does not clearly increase the risk of cardiorespiratory complications in patients undergoing endoscopy procedures.

Sleep apnea is a serious medical condition that can raise a person’s risk for heart problems. It requires treatment. Learn more here.
