Abstract
Background Rocuronium can be used in patients with severe renal failure (creatinine clearance <30 ml/min) but the duration of muscle relaxation is longer and results in an increased risk of postoperative residual curarization. Rocuronium can be antagonized by sugammadex but the elimination of the complex they made (rocuronium-sugammadex complex) varies according to the renal function. Two case reports/series reported the use of rocuronium – sugammadex complex during renal transplantation. This retrospective case-control study aimed to investigate the effects of rocuronium – sugammadex, used during the renal transplantation, on transplanted kidney function.Methods We analyzed 113 medical records of patients undergoing kidney transplantation from January 2015 to December 2018. 47 medical records were excluded because they did not report the administration of rocuronium + sugammadex or cisatracurium + neostigmine during the transplantation. For each medical records the following data were recorded the characteristics of patients and of kidney donor. Blood creatinine, blood urea, blood sodium, blood potassium, blood calcium levels were collected at the day before the surgery, the day of surgery, after 6 hours (hrs), 12 hrs, 24 hrs, 48 hrs and 72 hrs. Diuresis, urinary sodium and urinary potassium levels were collected at the day of surgery, after 6 hrs, 12 hrs, 24 hrs, 48 hrs and 72 hrs. Results We collected data from 66 medical reports. Blood creatinine levels at 6 hrs, 12 hrs and 24 hrs were significantly lower in roc + sug group than cis + neo group (crea 6 hrs =0.05, crea 12 hrs p=0.038, crea 24 hrs p= 0.049). Blood urea levels for 24 hrs after the transplantation were significantly lower in in roc + sug group than cis + neo group (urea 0 hrs p=0.025, urea 6 hrs p= 0.011, urea 12 hrs p=0.03, urea 24 hrs p=0.011). We found no statistically significant differences in blood sodium, blood potassium, blood calcium, diuresis, urinary sodium, urinary potassium levels before and after the transplantation.Conclusions In this retrospective case-control study, the use of rocuronium and sugammadex during the renal transplant surgery did not affect the recovery of the graft function during the first week after the transplantation.
