Single Dose Morphine and Fentanyl Added to Intrathecal Mixture on Orthopedics Patients With Undiagnosed Obstructive Sleep Apnea

December 18, 2013 updated by: University of Malaya

Randomized Comparison Study of Single Dose Morphine and Fentanyl Added to Intrathecal Mixture on Orthopedics Patients With Undiagnosed Obstructive Sleep Apnea

Obstructive Sleep Apnea (OSA) is a common clinical problem with a reported prevalence of 2% to 4% in the general population. The incidence was double on patients who had a diagnosis of OSA going for orthopedics surgery.

Little literature composed mostly of case reports or small retrospective case-control studies exist examining the use of intrathecal opioids on outcomes in OSA patients is inconclusive. The primary objective of this study is to compare the post operative respiratory effect after single dose intrathecal morphine and intrathecal fentanyl on orthopedics patients who suspected or undiagnosed obstructive sleep apnea.

Hypotheses

Undiagnosed OSA patients who received intrathecal morphine are more likely to have respiratory events post-operatively.
