We Have Two Groups. Both Groups Received a Deep Serratus Anterior Plane Block. One Group Had a Catheter for Continuous Infusion, While the Other Received IV Analgesics Postoperatively. Analgesic Effects Between the Two Groups Were Compared

A Comparative Study on the Analgesic Efficacy of Ultrasound-Guided Continuous Catheter-Based Deep Serratus Anterior Plane Block Versus Single-Injection Deep Serratus Anterior Plane Block in Patients Undergoing Breast Surgery

Brief summary

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?

Interventions

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.

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.
