Perioperative management of adult cadaveric and live donor renal transplantation in the UK: a survey of national practice

BACKGROUND: There is a limited evidence base and no national consensus regarding the perioperative management of patients undergoing renal transplantation. We developed an electronic survey to capture an overview of renal transplant perioperative practice across UK renal transplant centres and determine the need for future guidelines on patient management. METHODS: A 29-question survey was developed to encompass the entire renal transplant perioperative pathway and input was sought from clinicians with expertise in renal transplant surgery, anaesthesia, nephrology and intensive care. The survey was sent to lead renal anaesthetists at each of the 23 transplant centres across the UK. RESULTS: A 96% response rate was achieved with 22 out of 23 centres returning complete responses. There was limited evidence of guideline-based approaches to preoperative workup. Questions regarding intraoperative fluid management, blood pressure targets, vasopressor administration and central venous pressure (CVP) monitoring identified a broad range of practice. Of note, the routine use of goal-directed fluid therapy based on cardiac output estimation was reported in six (27.3%) centres, while nine centres (40.9%) continue to target a specific CVP intraoperatively. In all, 12 (54.5%) centres perform transversus abdominis plane blocks with fentanyl-based patient-controlled analgesia as the most common mode of postoperative analgesia. A single centre reported a renal transplant-specific Enhanced Recovery after Surgery programme for cadaveric organ recipients. CONCLUSIONS: This questionnaire highlighted a high degree of heterogeneity in current UK practice as regards the perioperative management of renal transplant recipients. Development of evidence-based national consensus guidelines to standardize the perioperative care of these patients is recommended in order to improve patient outcomes and focus areas of future research.
