RESUMO
PURPOSE: A case of deafness is reported in a patient undergoing bilateral nephrectomy after single irrigation of the peritoneal cavity with a neomycin containing solution for surgical prophylaxis. CLINICAL FEATURES: In this patient, profound, late-postoperative deafness was heralded by prolonged neuromuscular blockade and respiratory insufficiency. Additional risk factors for ototoxicity in this particular patient included the presence of end-stage renal disease requiring daily peritoneal dialysis and, possibly, the concomitant use of clonazepam and clindamycin. CONCLUSIONS: Antibiotic irrigation solutions containing neomycin may produce unwanted adverse systemic effects of deafness and prolonged neuromuscular blockade, even with only brief application within the peritoneal cavity. Concurrent end-stage renal disease, visceral inflammation from chronic dialysis and laparotomy, and the concomitant use of other medications may have contributed to these unwanted effects.
