About

The goal of this observational study is to learn about the effect of supplemental oxygen therapy during the first night after bariatric and metabolic surgery in a population that is not (routinely) tested for obstructive sleep apnea preoperatively.

The main question to answer in this study is:

How many desaturations occur while participants receive supplemental oxygen therapy and how many, and what type of nursing interventions are needed? Another question we want to answer is: are there characteristics that seems to increase the risk of developing a desaturation?

Full description

This is a prospective observational study that aims to characterize the number of desaturations and nursing interventions in a population with a unknown structive sleep apnea status receiving supplemental oxygen therapy during the first night after metabolic and bariatric surgery. The secondary aim is to to identify patient characteristics that are associated with a higher risk of developing desaturations.

Methods:

Participants receive standard of care, which includes 2 liters of supplemental oxygen therapy during the first postoperative night after metabolic and bariatric surgery while being continously monitored.

The desaturations, saturation and number and type of nursing intervention were collected along with patient characteristics (see outcomes) Sample size: A population proportion sample size was used, a CI 95%, margin of error 5% , proportion of 0.50, gave a required sample size of 385 participants.

Mann Whitney U-test (continuous data) and Fishers exact test (categorical data) are used to compare spo2 and nursing interventions between participants with and without desaturations.

Binary logistic regression will be used to estimate the risk for developing desaturations.
