Haemofiltration is a useful method for removing fluid overload in paediatric patients undergoing open heart surgery. However, its role in reducing the inflammatory response to cardiopulmonary bypass (CPB) is still controversial. This study was undertaken to examine the efficacy of haemofilter in reducing the inflammatory response to CPB in paediatric patients undergoing open heart surgery.

We studied 20 paediatric patients undergoing open heart surgery with long duration CPB. In ten patients conventional methods of suppressing inflammation, like aprotinin and methylprednisolone were used and in the other ten patients, haemofiltration was added to the conventional methods. Inflammatory response was assessed by increase in total white blood cell counts and decrease in complement factor 3 (C3) levels. Patients were followed up …
