Brief summary

The purpose of the study is to evaluate the effect of continuous pectoral nerve block on postoperative analgesia consumption in breast cancer surgery.

Detailed description

Pectoral nerve 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 in breast cancer surgery.

Interventions

Measure	Time frame	Description
analgesia consumption	12 hours	postoperative 12 hours

Secondary

Measure	Time frame	Description
analgesia consumption	during the surgery	intraoperative
postoperative Numeric Rating Scale (NRS) score	0, 1, 3, 6, 9, 12 hours	postoperative pain assessment will be performed using NRS score (NRS 0=no pain, NRS 10= most severe possible). The NRS scores will be recorded at postoperative 0, 1, 3, 6, 9, 12 hours
