NCT07174674

Brief Summary

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?

Outcome Measures

Primary Outcomes (3)

  • Number of desaturations per patient

    Participants were continuously monitored and all desaturations (spo2\<90%) were collected.

    First postoperative night

  • Number of nursing interventions

    If nurses had to intervene because of a desaturation or to prevent a desaturation (e.g. waking patient, putting back nasal cannula, increasing oxygen flow)

    First postoperative night

  • Type of nursing intervention

    which nursing intervention the nursed provided was documented on a form (e.g. putting back nasal cannula, increasing oxygen flow, jaw thrust)

    First postoperative night

Secondary Outcomes (13)

  • The effect of the patient characterisic "sex" on the risk of developing desaturations

    First postoperative night

  • The effect of the patient characterisic "age" on the risk of developing desaturations

    First postoperative night

  • The effect of the patient characterisic "body mass index" on the risk of developing desaturations

    First postoperative night

  • The effect of the patient characterisic "smoking status" on the risk of developing desaturations

    First postoperative night

  • The effect of the patient characterisic "chronic benzodiazepine use" on the risk of developing desaturations

    First postoperative night

  • +8 more secondary outcomes

Other Outcomes (1)

  • Saturation during the night

    First postoperative night
