Sleep after laparoscopic cholecystectomy

S Rosenberg-Adamsen1, M Skarbye, G Wildschiødtz

Summary

Laparoscopic cholecystectomy patients experienced reduced slow wave sleep (SWS) post-operation, though overall sleep patterns and oxygenation remained stable. Opioid-free analgesia may mitigate sleep disturbances compared to open surgery.

Area of Science:

  • Anesthesiology
  • Sleep Medicine
  • Surgical Outcomes

Background:

  • Postoperative sleep disturbances are common after major surgery.
  • The impact of minimally invasive procedures like laparoscopic cholecystectomy on sleep architecture is less understood.
  • Opioid administration is a suspected contributor to sleep disruption.

Purpose of the Study:

  • To investigate the effects of laparoscopic cholecystectomy on sleep patterns and oxygenation.
  • To compare postoperative sleep changes with preoperative sleep in opioid-naïve patients.
  • To explore factors influencing postoperative sleep disturbances.

Main Methods:

  • Polysomnography was used to monitor sleep stages and oxygenation in 10 patients.
  • Sleep was recorded the night before and the first night after surgery.

  • General anesthesia was administered, with analgesia managed without opioids.

    • Main Results:

    • No significant changes in total awake time or arousals were observed.
    • A significant decrease in slow wave sleep (SWS) and a corresponding increase in stage 2 sleep occurred postoperatively.
    • Arterial oxygen saturation and rapid eye movement (REM) sleep proportions remained unchanged.

    Conclusions:

    • Laparoscopic cholecystectomy, even without opioids, can alter sleep architecture, specifically reducing SWS.
    • The findings suggest that surgical invasiveness and opioid use may be key factors in postoperative sleep disturbances.
    • Further research is needed to fully elucidate the mechanisms behind sleep changes after minimally invasive surgery.
