Brief Summary

The best perioperative strategy for obstructive sleep apnea (OSA) in bariatric surgery remains unclear. A strategy is to monitor patients and administer preventive oxygen therapy during the first postoperative night. However it is unknown what if preventive oxygen therapy is necessary. The goal of this trial is to compare the Apnea-Hypopnea Index (AHI) in participants with or without preventive oxygen therapy. Methods: Participants are patients who underwent bariatric surgery without treated OSA and will be will be randomized into arm A or arm B: Arm A: First postoperative night in the hospital with preventive oxygen therapy (standard care), Arm B: First postoperative night in hospital without preventive oxygen therapy (intervention).

Outcome Measures

Primary Outcomes (1)

  • Apnea-Hypopnea Index (AHI)

    AHI will be measured by a home sleep study device (Watchpat300) and will be compared between both arms, the higher the AHI the more severe the sleep apnea

    First postoperative night

Secondary Outcomes (24)

  • Complication rate

    Until 30 days after surgery

  • The number of nursing interventions

    First postoperative night

  • Type of nursing interventions

    First postoperative night

  • Oxygen Desaturation Index (ODI)

    First postoperative night

  • AHI during Rapid Eye Movement (REM) sleep

    First postoperative night

  • +19 more secondary outcomes

Study Arms (2)

Without preventive oxygen therapy

EXPERIMENTAL
Other: No preventive oxygen therapy (2L)

With preventive oxygentherapy

ACTIVE COMPARATOR
Other: Preventive oxygen therapy (2L) standard care

Interventions

Participants will not receive preventive oxygen 2L during the first postoperative night after bariatric surgery.

Without preventive oxygen therapy

Participants will receive preventive oxygen 2L during the first postoperative night after bariatric surgery, standard care.

With preventive oxygentherapy
