Injection Rate and Erector Spinae Plane Block

Antalya Training and Research Hospital60 enrolled

Overview

To evaluate the effect of injection rate on the block sensory level in the ESP block.

Many women experience severe acute postoperative pain after breast cancer surgery. Regional techniques are frequently used as a part of multimodal analgesia in breast surgery. Ultrasound-guided erector spinae plane (ESP) block is a preferred method to reduce the postoperative opioid requirement for postoperative pain management. In this study, we aimed to evaluate the effect of injection rate on the block sensory level in the ESP block.

Outcomes

Primary Outcomes

Block sensory level

Number (average) of dermatomes with sensory block with pinprick and cold methods after the ESP block

Time frame: 12 hours

Secondary Outcomes

Postoperative tramadol consumption

Postoperative tramadol consumption will be recorded at 24 hours

Time frame: 24 hours

Assesment of postoperative analgesia

Post operative pain scores will be assessed using a numerical rating scala (NRS) (from 0=no pain, to10= worst pain imaginable).

Time frame: 24 hours
