Keywords

pectoral nerve block (PECS block), breast reduction surgery, ultrasonography, postoperative pain, VAS score

Brief summary

The purpose of the study is to evaluate the efficacy of PECS block applied to patients undergoing bilateral breast reduction surgery on postoperative analgesia compared to local infiltration anesthesia.

Detailed description

Pectoral nerve block (PECS block) has been developed as an alternative to thoracic paravertebral and/or thoracic epidural blocks in recent years. It is frequently applied for postoperative analgesia especially in breast cancer surgery and subpectoral breast prosthesis.

Interventions

Pecs block performed using ultrasound guidance

Design outcomes

Primary

Measure	Time frame	Description
postoperative visual analog scale (VAS) score	postoperative 0, 1, 3, 6, 9, and 12 hours	Postoperative pain assessment will be performed using the VAS score (VAS 0 = no pain, VAS 10 = most severe pain possible). The VAS scores will be recorded at postoperative 0, 1, 3, 6, 9, and 12 hours.

Secondary

Measure	Time frame	Description
analgesia consumption	12 hours	postoperative
length of hospital	4 days	recorded at the following time after surgery
