Pain Control and Recovery After Thoracic Surgery Using SPSIP Block
Comparison of the Analgesic Effectiveness of Ultrasound-Guided Serratus Posterior Superior Intercostal Plane Block Among Different Thoracic Surgical Procedures: A Prospective Observational Cohort Study
Thoracic surgery is frequently associated with significant postoperative pain, which may impair respiratory function, mobilization, recovery, and patient satisfaction. The Serratus Posterior Superior Intercostal Plane (SPSIP) block is a recently described ultrasound-guided fascial plane block that may provide effective analgesia after thoracic surgery. This prospective observational cohort study will evaluate the analgesic effectiveness and postoperative recovery associated with SPSIP block in adult patients undergoing elective minor video-assisted thoracoscopic surgery (VATS), major VATS, or thoracotomy. All patients will receive SPSIP block as part of routine institutional multimodal analgesia. The primary outcome will be postoperative quality of recovery assessed using the Quality of Recovery-15 (QoR-15) questionnaire at 24 hours after surgery. Secondary outcomes will include postoperative pain intensity, opioid consumption, rescue analgesic requirements, postoperative nausea and vomiting, pulmonary complications, patient satisfaction, length of hospital stay, and chronic postoperative pain.
調査の概要
詳細な説明
Postoperative pain remains an important clinical concern following thoracic surgery. Inadequate analgesia may adversely affect deep breathing, coughing, pulmonary toilet, early mobilization, and overall postoperative recovery. Although minimally invasive thoracic surgical techniques have reduced surgical trauma, clinically relevant postoperative pain may still occur. Regional anesthesia techniques are commonly incorporated into multimodal analgesic strategies for thoracic surgery. Fascial plane blocks have emerged as alternatives to more invasive regional techniques because of their relative technical simplicity and potential safety advantages. The Serratus Posterior Superior Intercostal Plane (SPSIP) block is a recently described ultrasound-guided fascial plane block with promising analgesic efficacy; however, evidence regarding whether its effectiveness differs according to the invasiveness of the thoracic surgical procedure remains limited.
This prospective observational cohort study will include adult patients undergoing elective thoracic surgery under general anesthesia who receive an ultrasound-guided SPSIP block as part of routine institutional multimodal analgesia. Patients will be categorized according to the surgical procedure into three predefined cohorts: minor video-assisted thoracoscopic surgery (VATS), major VATS, and thoracotomy. The SPSIP block will be performed after induction of general anesthesia according to routine institutional clinical practice using a long-acting local anesthetic. No participant will be assigned to a surgical procedure or regional anesthesia technique for research purposes.
The primary objective is to compare postoperative quality of recovery among the three surgical cohorts. Quality of recovery will be assessed using the 15-item Quality of Recovery questionnaire (QoR-15) at 24 hours after surgery, with higher scores indicating better postoperative recovery.
Secondary outcomes will include postoperative opioid consumption expressed as morphine milligram equivalents, pain intensity measured using the Numeric Rating Scale at rest and during coughing, time to first rescue analgesia, total rescue analgesic requirement, postoperative nausea and vomiting, antiemetic requirement, hemodynamic variables, pulmonary complications, time to ambulation, length of hospital stay, and patient satisfaction. Pain intensity will be evaluated in the post-anesthesia care unit and at 2, 6, 12, and 24 hours after surgery. Patients will also be followed for clinically relevant postoperative outcomes, including hospital readmission within 30 days and chronic postoperative pain at 3 and 6 months. Potential block-related complications, including local anesthetic systemic toxicity, pneumothorax, hematoma, and infection, will be recorded.
The study is designed to determine whether postoperative recovery and analgesic outcomes associated with the same SPSIP block technique differ according to the type and invasiveness of thoracic surgery.
