Effectiveness of Peritoneal Dialysis in Management of Acute Hyperthermia after On-Pump Heart Surgery in Infants
Introduction: Acute hyperthermia is a common complication in the first 24 hours after open heart surgery with the incidence of 12% to 73%. The aim of this study was to evaluate the efficiency of postoperative peritoneal dialysis for controlling acute hyperthermia in pediatrics undergoing on-pump heart surgery. Methods: We reviewed clinical outcomes of 40 infants who underwent congenital surgery from August 2016 to August 2017. Patients were divided into two groups in terms of peritoneal dialysis requirement as group A and B. Demographic data, intraoperative and postoperative variables were compared between the patients. Results: Among the 40 high risk infants who underwent cardiac surgery, 20 patients were treated with peritoneal dialysis (group A). Mean rectal temperature and incidence of acute hyperthermia in 24h after surgery were higher in group A compared to group B (p ˂ 0.05). Infants in group A were younger, lighter and showed lower BSA compare to group B (p < 0.05). Also, higher concentration of serum potassium and lower urinary output were seen in group A compared to group B (p = 0.05). The incidence of neurological events was significantly higher in patients of group A (p < 0.05). Intubation time and intensive care unit stay was significantly more prolonged in the group A with peritoneal dialysis (p ˂ 0.05). Conclusion: Peritoneal dialysis performance was effective in treatment of induced hyperthermia in the first 24 h after operation. Indeed, younger age and lighter weight children are more prone to postoperative complication related to cardiopulmonary bypass surgery.
