Abstract
With the advancement of dialysis therapies, the chance of performing open-heart surgery for patients with chronic dialysis therapies has been increasing. In performing open-heart surgery in such cases we use, at our institution, the hemofiltration (HF) system concurrently with the extracorporeal circulation system. With this method we have been able to rehabilitate 6 patients out of 7 who are on chronic dialysis therapies. By conducting HF dring the extracorporeal circulation, the postoperative fluild/electrolyte control could be managed conservatively on the operation day and the BUN/CRE values on the following day could also be well controlled. Thus, it was made possible to resume bemodialysis (HD) in a usual manner from the day following the operation day. Also, concerning data on timing for postoperative weaning from respirators and c atecholamines, ICU-stay days and hospital-stay days, no significant differences were recognized between the dialysis cases and the recenty, consecutive 100 cases of open-heart surgery with normal renal functions in which no complications were observed at both pre-and post-operative stages. Based on the observations summarezed above, it could be said that open-heart surgery in patients with chronic dialysis therapies could be performed as safely as in patients with normal renal functions by conducting HF together with extracorporeal circulation and the surgical results would by no means be inferior to those O of normal cases in renal functions.
