Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this observational study is to compare the analgesic efficacy of continuous infusion via peripheral catheter versus single-shot serratus anterior plane block in women aged 18 to 80 undergoing breast-conserving surgery. The main questions it aims to answer are: Does continuous serratus anterior plane block via peripheral catheter provide superior postoperative analgesic efficacy compared to single-shot serratus anterior plane block? Second question is: Does continuous infusion via catheter in peripheral nerve blocks reduce the amount of intravenous analgesics consumed and improve patient comfort?

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

SAPB

The SAPB arm receives single shot deep serratus anterior plane block before surgery. Also receives iv analgesic treatment after post-operative duration.

Group Type ACTIVE_COMPARATOR

Serratus Anterior Plane Block (SAPB) group

Intervention Type PROCEDURE

The SAP block, which is among the chest wall blocks, provides its effect by blocking the lateral cutaneous branches of the T2-T9 intercostal nerves, n. intercostobrachial , n. longus thoracicus , n. thoracodorsal.

SAP block can be performed in two ways: superficial and deep. The deep SAP block is administered between the serratus anterior and intercostal muscles, at the intersection point of the anterior axillary line and the level of the nipple (at the level of the 4th-5th ribs).

It has a wide range of use for postoperative pain management in trauma surgery, cardiac surgery, thoracic surgery and breast surgery.

DSAPB

The DSAPB arm receives deep serratus anterior plane block and cathather replacement before surgery. After surgery, the arm takes continous analgesic treatment via periferic block cathather.

The deep SAP block is administered between the serratus anterior and intercostal muscles, at the intersection point of the anterior axillary line and the level of the nipple (at the level of the 4th-5th ribs). Following hydrodissection between the serratus anterior and intercostal muscles, a single-shot injection is administered. Subsequently, a peripheral nerve block catheter is placed in the same region under ultrasound guidance.
