Intraoperative QRS-interval changes caused by hyperkalaemia in an infant with Arima syndrome.

A one-year-and-ten-months-old male infant with Arima syndrome, a very rare genetic disorder, underwent urgent insertion of a catheter for continuous ambulatory peritoneal dialysis (CAPD) under general anaesthesia. During the procedure he showed QRS-interval changes caused by hyperkalaemia which was successfully treated with calcium gluconate. The management and intraoperative complications of this syndrome are reported and available literature reviewed.
