Introduction. Tumescent local anesthesia (TLA) is widely used for ambulatory surgery. Patients with transplanted organs are on immunosuppressive therapy and with risk for organ rejection or severe infection. Case report. Saphenectomy with phlebectomy on the left leg under TLA was performed in a patient with kidney transplantation performed four years ago. A combination of 35 mg of 1% prilocaine-hydrochloride, 5 mL of 8.4% sodium bicarbonate and 500 μg of epinephrine in 460 mL of normal saline was used for TLA. Overall 750 mL of the solution was used. The patient had satisfactory postoperative analgesia and was discharged home on the same day. Blood levels of urea, creatinine, estimated glomerular filtration rate (eGFR) and tacrolimus concentration, measured preoperatively and on the second postoperative day, were in a regular range. Prilocaine blood concentrations determined on the 4th, 10th and 16th postoperative hours, were below toxic levels. Conclusion. TLA in a kidney-transplanted patient performed for saphenectomy with phlebectomy proved to be a safe and reliable anesthesia method.
