简要总结
This study compared the postoperative analgesic efficacy of ultrasound-guided erector spinae plane (ESP) block and retrolaminar block in patients undergoing video-assisted thoracoscopic surgery (VATS). Adult patients were randomly assigned to receive either an ESP block or a retrolaminar block after induction of general anesthesia. Postoperative pain intensity was assessed using the Numeric Rating Scale (NRS) at predefined time points. Postoperative analgesic requirements and intraoperative opioid consumption were also evaluated.
详细描述
This prospective, randomized study was conducted in adult patients undergoing video-assisted thoracoscopic surgery (VATS) under general anesthesia. Participants were randomly assigned to receive either an ultrasound-guided erector spinae plane (ESP) block or an ultrasound-guided retrolaminar block after induction of general anesthesia.
The primary objective was to compare postoperative pain intensity between the two regional analgesic techniques. Pain intensity was assessed using the Numeric Rating Scale (NRS) at 1, 6, 12, and 24 hours after surgery. Additional outcomes included postoperative analgesic requirements, intraoperative remifentanil consumption, postoperative nausea and vomiting, and procedural characteristics of the blocks.
Postoperative pain assessment was performed by an investigator blinded to group allocation. The clinician responsible for determining the need for rescue analgesia was also unaware of the assigned block technique.

盲法说明
The investigator responsible for postoperative pain assessment using the Numeric Rating Scale (NRS) was blinded to group allocation. The clinician responsible for determining the need for rescue analgesia was also unaware of the assigned block technique. The anesthesiologist performing the block was not blinded due to the nature of the intervention

研究组 & 干预措施
Erector Spinae Plane Block Group
Participants assigned to this group received an ultrasound-guided erector spinae plane (ESP) block after induction of general anesthesia. The block was performed as part of the perioperative analgesia protocol for video-assisted thoracoscopic surgery.
干预措施: Erector spinae plane block (ESP) (Procedure)
Retrolaminar Block Group
Participants assigned to this group received an ultrasound-guided retrolaminar block after induction of general anesthesia. The block was performed as part of the perioperative analgesia protocol for video-assisted thoracoscopic surgery.
干预措施: Retrolaminar block group (Procedure)
结局指标
主要结局
Postoperative Pain Intensity Assessed Using the 11-Point Numeric Rating Scale
时间窗: 1, 6, 12, and 24 hours after surgery
Postoperative pain intensity was assessed using the 11-point Numeric Rating Scale, ranging from 0 to 10, where 0 indicates no pain and 10 indicates the worst imaginable pain. Higher scores indicate greater pain intensity and therefore a worse outcome. Pain scores were recorded at 1, 6, 12, and 24 hours after surgery.
次要结局
- Postoperative Analgesic Requirement(Within the first 24 hours after surgery)
- Intraoperative Remifentanil Consumption(From induction of anesthesia until the end of surgery)
- Postoperative Nausea and Vomiting (PONV)(Within the first 24 hours after surgery)
- Number of Block Attempts(During block performance procedure)
