EP.WE.103223-hour stay following total parathyroidectomy in renal patients

Abstract Aim Total parathyroidectomy in end-stage renal failure (ESRF), is an effective way to improve or stabilise calcium and parathormone levels and thus improve renal osteodystrophy. Previous BAEST guidelines were not in favour of true day-case neck surgery due to the risk of airway compromise from bleeding. Additionally, ESRF patients are at risk of profound hypocalcaemia after total parathyroidectomy. Patients undergoing total parathyroidectomy are prescribed Alfacalcidol 4mcg daily for 5 days prior to surgery. Following surgery under GA on a morning list, the potassium and calcium levels are checked in the afternoon. Calcium levels are then monitored daily for 3 days and subsequently when required. Oral Alfacalcidol is continued at the same dose until the nephrologists advise otherwise. Methods All ESRF patients undergoing total parathyroidectomy for secondary hyperparathyroidism were identified between 01/01/2005 and 31/12/2019 from a prospectively maintained electronic database. Demographics, biochemistry, length of stay (LoS) and outcomes were analysed. Results There were 43 (30 male) total parathyroidectomies. The median age was 53 (range 14 – 78), and median LoS 1 day (range 0 -13). 26 patients (60%) were discharged within 23 hours (26% were day-case). Prolonged stay was due to calcium replacement (n = 8) or dialysis (n = 4) requirements. Pre- and post-operative calcium values over 2.49mmol/L were significantly related to 23-hour stay (p = 0.010482 and p = 0.000263 respectively). No 30-day re-admissions were observed Conclusions Careful patient selection and adherence to a perioperative management protocol in total parathyroidectomy may enable early discharge within 23 hours. Preoperative calcium levels help predict this outcome.
