Brief summary

In this study, we compared ultrasound-guided modified pectoral nerve (PECS) block and bi level erector spinae plane (ESP) block on postoperative analgesic effect in breast surgery.

Detailed description

After being informed about the study and potential risks, written consent was obtained from all patients. Patients who meet eligibility requirements will be randomized in a 1:1 ratio to bi- level erector spinae plane block and modified pectoral block.

Interventions

OTHERUltrasound guided bi-level erector spinae plane block

Bi-level ultrasound (US)-guided Erector spinae plane block (ESP) with 30 ml 0.25% bupivacaine at the T2 andT4 vertebral level will performe preoperatively to all patients in the ESP group.

OTHERUltrasound guided modified pectoral nerve block

Ultrasound (US)-guided modified pectoral nerve block (PECs) with 30 ml 0.25% bupivacaine will performe preoperatively to all patients in the PECs group.

Design outcomes

Primary

Measure	Time frame	Description
Morphin consumption	during postoperative 24 hour	Patients in both groups will provide with intravenous patient-controlled analgesia device containing morphine for postoperative analgesia.
numerical rating scale (NRS)	during postoperative 24 hour	A numerical rating scale (NRS) requires the patient to rate their pain on a defined scale. For example, 0-10 where 0 is no pain and 10 is the worst pain imaginable
