Adaptation of the Fresenius PD+ Cycler for a hearing-impaired patient.
Continuous cycling peritoneal dialysis (CCPD) uses a cycler to perform dialysis exchanges and requires the patient to respond to an audible alarm signifying an interruption in the therapy. Consequently, an unassisted hearing-impaired patient could not use the system. By converting the standard alarm to a vibrating signal, the cycler was successfully adapted to accommodate the special needs of our hearing-impaired patient. The items required for the modification were the Sonic Alert Wake Up Alarm (Model SA-WA300: Sonic Alert, Troy, MI, U.S.A.) and the Sonic Alert Super Shaker Bed Vibrator (Model SA-SS120V: Sonic Alert). The patient can place the vibrator under either the pillow or the mattress. When the cycler alarm is activated, vibration wakens the patient. The equipment was purchased from Harris Communications (Eden Prairie, MN, U.S.A.) through a referral by the Easter Seal Society. Three days were needed to complete training compared to an average of one or two days for patients previously trained for continuous ambulatory peritoneal dialysis (CAPD). The patient remained on cycler therapy for approximately four months when the unrelated development of an abdominal hernia required termination of peritoneal dialysis and subsequent transfer to hemodialysis. In conclusion, a modified cycler can provide a safe and efficient renal replacement therapy option for a hearing-impaired patient.
