The Effect of Thoracic Paravertebral Block on Postoperative Pain After Coronary Artery Bypass Graft Surgery: A Retrospective Study
Authors' conclusion
In this retrospective study, PVB was associated with superior analgesia, decreased opioid consumption, and improved early recovery parameters.
Study context
- Population
- Patients undergoing elective coronary artery bypass grafting (CABG) surgery, single tertiary university hospital
- Participants
- 110 patients
- Exposure
- GA plus bilateral single-shot thoracic paravertebral block (PVB) vs GA alone
- Group Bn = 51
- Group Cn = 59reference
- Outcome
- Postoperative analgesia
Methodological detailssingle-centre
- Single-centre
Main finding
As reported in the abstract
Postoperative pain (VAS at 2, 4, 16 and 24 hours)
- VAS scores significantly lower in Group B
- Group B vs Group C: P < 0.05
Observational data: associations, not effects.
Further findings
| Outcome | P value |
|---|---|
| Intraoperative fentanyl and postoperative paracetamol use | P < 0.05 |
| Extubation time, ICU LOS, time to mobilization | P < 0.05 |
| Total hospital LOS, chest drain removal time | P > 0.05 |
Intraoperative fentanyl and postoperative paracetamol use
- Significantly lower in Group B
Extubation time, ICU LOS, time to mobilization
- Significantly shorter in Group B
Total hospital LOS, chest drain removal time
- No significant differences
