Brief summary

In this study, the investigators compared ultrasound-guided erector spinae plane (ESP) block and rhomboid intercostal block (RIB) on postoperative analgesic effect in unilateral 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 erector spinae plane block and rhomboid intercostal block.

Interventions

OTHERErector Spinae Plane Block

Ultrasound(US)-guided erector spinae plan block(ESP) with 20 ml 0,25% bupivacaine at T4 vertebra level will performe preoperatively to all patients in the ESP group.

OTHERRhomboid Intercostal Block

Ultrasound(US)-guided rhomboid intercostal block(RIB) with 20 ml 0,25% bupivacaine at T5-T6 vertebra level will performe preoperatively to all patients in the RIB group.

Design outcomes

Primary

Measure	Time frame	Description
Morphin Consumption	during postoperative 24 hours	Patients in both groups will provide with intravenous patient-controlled analgesia device containing morphine for postoperative analgesia

Secondary

Measure	Time frame	Description
Numerical Rating Scale(NRS)	during postoperative 24 hours	A numerical rating scale(NRS) requires the patient to rate their pain on defined scale.For example , 0-10 where 0 is no pain and 10 is the worst pain imaginable.
