简要总结
The erector spinae plane (ESP) block is a novel regional anesthetic technique for the treatment of thoracic, cervical, and abdominal pain. This pilot study aims to investigate the post-operative analgesic effectiveness of ultrasound guided single-shot ESP blocks for patients undergoing minimally invasive thoracoscopic wedge resections of the lung in comparison to those receiving conventional parental opioid analgesia alone. This will be achieved through the use of objective measures including quality the 40 point Quality of Recovery assessment (QoR-40) on postoperative day (POD) 1, visual-analogue pain scale (VAS) in the post-anesthetic care unit (PACU) and at POD 1, and oral morphine-equivalent (OME) opioid consumption in the PACU and at 24 hours post-operatively.
详细描述
Purpose To investigate the postoperative analgesic effectiveness of the ultrasound-guided ESP block compared to a placebo injection for patients undergoing thoracoscopic wedge resection of the lung.
Hypothesis Thoracoscopic surgery patients who receive an ESP block in addition to current standard of care, consisting of parenteral and enteral opioids and surgical wound infiltration, will have a clinically significant improvement in their QoR-40 at POD 1 and lower pain levels, as measured by VAS in the PACU on arrival and one hour after, and on POD 1, and OME opioid consumption in the PACU and at 24 hours post-operatively, in comparison to those patients who receive the current standard of care along with a placebo injection.
Justification The ESP block is a novel regional anesthetic technique that has shown efficacy in the management of thoracic pain as published in numerous case reports and observational case series. To date, no randomized control trials exist of its efficacy in comparison to conventional parental opioid analgesic management. Thoracoscopic wedge resections of the lung are procedures not usually treated with regional analgesia techniques, but given the moderate pain experienced by many patients, this surgical population will serve as a proof-of-concept for the potential of improved post-operative analgesic and recovery profiles. Proof of analgesic efficacy in this setting may allow a future head-to-head comparison with more invasive analgesic techniques currently used for thoracic surgery such as epidural and paravertebral catheterizations.
In undertaking this aim, we will measure a number of different metrics. The 40-item Quality of Recovery Score (QoR-40) will be our primary objective as it provides a patient-centered global measure of overall health in the postoperative period. It has been tested for validity and reliability, and has undergone quantification for the minimal clinically important difference. Other traditional metrics of analgesic performance including the VAS and 24-hour post-op OME opioid consumption will also be monitored as secondary objectives.

盲法说明
Recruited patients will be allocated to an experimental or placebo-control arm. Patients in the experimental arm will receive an ESP block prior to induction of general anesthetic for their thoracoscopic wedge resection, while patients allocated to the placebo-control arm will receive a placebo injection of normal saline in a fashion almost identical to that of the ESP block.

结局指标
主要结局
Quality-of-Recovery 40 (QoR-40) scale at POD 1.
时间窗: Postoperative day 1. Will be completed on the ward 24hrs after surgery
The QoR-40 is a widely used and extensively validated measure of quality of recovery
次要结局
- Morphine usage(30 minutes post-operatively in the PACU and 24hr after surgery.)
- Visual analog pain scale (VAS) assessments post-operatively in PACU, and at POD 1.(30 minutes post-operatively in the PACU and 24hrs after surgery)
