This systematic review and meta-analysis evaluated the effects of stellate ganglion block (SGB) on postoperative sleep disturbance in 734 participants from 10 randomized controlled trials. SGB significantly improved subjective sleep scores on the night of surgery (SMD, -2.09) and on postoperative days 1 (-2.27) and 3 (-1.12), as well as increased total sleep time by approximately 72 minutes.
Key findings
- SGB reduced subjective sleep scores on the night of surgery with an SMD of -2.09.
- On postoperative day 1, SGB showed an SMD of -2.27 for sleep scores.
- Total sleep time increased by approximately 72 minutes with SGB.
- Substantial heterogeneity was noted for sleep efficiency and subjective sleep quality.
Why it matters
Postoperative sleep disturbance can significantly affect recovery and overall patient satisfaction. Understanding interventions like SGB that may enhance sleep quality can inform postoperative care strategies and improve patient outcomes.
What to keep in mind
The included trials had limited geographic diversity and substantial heterogeneity, which may affect the generalizability of the findings.
