Perioperative medicine & outcomes
Association between preoperative frontal electroencephalogram alpha asymmetry and postoperative quality of recovery: an observational study
Authors' conclusion
Preoperative left-sided frontal alpha asymmetry was independently associated with a lower postoperative QoR-15 score in female patients undergoing thyroidectomy
Study context
- Population
- Female patients undergoing thyroidectomy
- Participants
- 110 patients
- Exposure
- Preoperative left-sided vs right-sided frontal alpha asymmetry
- Outcome
- Difference in postoperative global QoR-15 score between preoperative left-sided and right-sided alpha asymmetry groups
- Follow-up
- POD 1 and 2
Main finding
As reported in the abstract
Global QoR-15 score
- Significant group-by-time interaction
- Left-sided frontal alpha asymmetry vs Right-sided frontal alpha asymmetry: P = 0.006
- Left-sided frontal alpha asymmetry vs Right-sided frontal alpha asymmetry: P < 0.001
Observational data: associations, not effects.
Further findings
| Outcome | 3.3-fold increased risk (95% CI) | P value |
|---|---|---|
| Lowest tertile of POD 1 QoR-15 score (multivariate logistic regression) | 3.3 (1.31–8.24) | P = 0.011 |
