Paravertebral blockade (PVB) offers better pain relief for breast surgery patients compared to general anesthesia (GA). However, its routine use for minor procedures is not recommended due to a less favorable risk/benefit ratio.

Area of Science:

Anesthesiology
Surgical Pain Management

Background:

Paravertebral blockade (PVB) is a proposed technique for managing breast surgery pain.
General anesthesia (GA) is a common anesthetic approach for breast surgeries.

Purpose of the Study:

To prospectively compare the efficacy of PVB via catheter with GA for minor breast surgery.
To evaluate postoperative pain, nausea/vomiting, recovery time, and patient satisfaction.

Main Methods:

Thirty patients undergoing minor breast surgery were randomized into PVB or GA groups.
Efficacy was measured using visual analog scale (VAS) for pain, incidence of PONV, recovery duration, and patient satisfaction scores.

Main Results:

PVB group showed significantly lower early postoperative VAS pain scores (12 mm vs 45 mm).

Postoperative nausea and vomiting (PONV) was minimal in both groups.

Patient satisfaction was higher in the PVB group (2.8 vs 2.3).

No significant difference in recovery time was observed.

Complications in the PVB group included one inadvertent epidural block and one pleural puncture.

Conclusions:

PVB provides superior pain relief compared to GA for breast surgery.
The advantages of PVB over GA were marginal for minor breast surgery due to mild pain and low PONV incidence.
The risk/benefit ratio does not currently support routine PVB use for minor breast surgery, considering potential complications.
