Serratus Posterior Superior Intercostal Plane Block in Minimally Invasive Cardiac Surgery
Preoperative Serratus Posterior Superior Intercostal Plane Block for Analgesia and Opioid Sparing in Patients Undergoing Minimally Invasive Cardiac Valve Surgery Via Mini-Thoracotomy: A Randomized, Double-Blind, Placebo-Controlled Trial
調査の概要
状態
詳細な説明
This study is a prospective, randomized, double-blind, placebo-controlled clinical trial designed to evaluate the analgesic efficacy of the serratus posterior superior intercostal plane (SPSIP) block in patients undergoing minimally invasive cardiac valve surgery via mini-thoracotomy. Postoperative pain following thoracic cardiac surgery may impair respiratory function and delay recovery, making effective analgesia essential.
Participants will be randomly assigned to receive an ultrasound-guided SPSIP block with either bupivacaine or normal saline under identical conditions. All patients will receive standardized general anesthesia and postoperative multimodal analgesia. Blinding will be ensured for patients and outcome assessors.
The study aims to determine whether SPSIP block with local anesthetic reduces postoperative opioid consumption and improves pain control compared to placebo.

Inspiratory Spirometry Test
時間枠:4, 6, 12, and 24 hours after surgery
|
Inspiratory spirometry performance will be assessed using an incentive spirometer.
Inspiratory capacity will be estimated based on the number of rising balls: 1 ball = 600 mL, 2 balls = 900 mL, and 3 balls = 1200 mL.
The score ranges from a minimum of 1 ball to a maximum of 3 balls, with higher scores indicating better inspiratory function.
