Continuous Erector Spinae Plane Analgesia in Kidney Transplant Recipients: A Quality Improvement Project

Abstract

IntroductionPain management in patients with chronic kidney disease is challenging. Due to impaired kidney function, analgesic options are limited. Postoperative analgesia in transplant recipients is further complicated by their vulnerability to infections, titrated fluid management and optimal haemodynamics to maintain graft function. Erector spinae plane (ESP) blocks have been used successfully in a variety of surgeries. This study is a quality improvement project aiming to assess the efficacy of continuous erector spinae plane catheter analgesia in the postoperative management of kidney transplant recipients. MethodsWe conducted an initial audit over a period of three months. All patients who underwent kidney transplantation under general anaesthesia with erector spinae plane catheters were included. Erector spinae plane catheters were secured prior to induction, and continuous local anaesthetic infusion was maintained postoperatively. Pain scores using the numerical rating scale (NRS) were recorded at intervals in the first 24 hours postoperatively, and supplementary analgesics given were noted. Following satisfactory results from the initial audit, we implemented erector spinae plane catheters as part of multimodal analgesia in transplant patients in our centre. We re-audited all transplants done over the next year to reassess the quality of postoperative analgesia. ResultsFive patients were audited during the initial audit. The average NRS score ranged from 0 at rest to a maximum of 5 during mobilisation. All patients were given only paracetamol to supplement analgesia, and none required opioids. During the re-audit, data was collected on postoperative pain management in 13 subsequent transplants conducted over the next year. The NRS scores ranged from 0 at rest to 6 on mobilisation. Two patients required boluses of fentanyl 25 mcg via the catheter, and the rest reported satisfactory analgesia with paracetamol as needed. ConclusionThis quality improvement project changed our centre's practice in managing postoperative pain in kidney transplantations. We switched from securing epidural catheters to erector spinae plane catheters due to better safety profile, minimal use of opioids and lesser adverse effects. We shall continue to re-audit our practices for the best outcomes.

Continuous Erector Spinae Plane Block for Pain Management in a Pediatric Kidney Transplant Recipient: A Case Report and Review of the Current Literature

“…Similar results were reported by Vishwanath et al [16]: in their quality improvement project, they switched from epidural catheters to erector spinae plane catheters in managing postoperative pain in 13 kidney transplantations. They reported a better safety profile, minimal use of opioids, and lesser adverse effects.…”
