OBJECTIVES/HYPOTHESIS: To analyze the incidence and severity of hyponatremia in patients receiving synthetic desmopressin (DDAVP) in the perioperative setting of oropharyngeal surgery in the treatment of von Willebrand disease and to propose a standardized protocol for perioperative fluid resuscitation and postoperative sodium monitoring after DDAVP administration. STUDY DESIGN: Retrospective medical record review. METHODS: A retrospective medical record review in an academic pediatric medical center was conducted. From October 1, 2002, to February 1, 2009, all patients undergoing adenotonsillectomy and receiving DDAVP preoperatively for the treatment of von Willebrand disease were identified. A total of 76 patients were identified by initial database review; 63 patients were included in the study, and 13 patients were excluded secondary to incomplete data. DDAVP dose and timing, perioperative fluid volume and composition, and postoperative sodium levels were collected. Extreme adverse events related to hyponatremia were recorded. RESULTS: Forty-seven of 63 (74.6%) patients developed some degree of hyponatremia after DDAVP administration, and six of 63 (9.5%) patients developed extreme hyponatremia, with the degree of hyponatremia related to the volume of perioperative fluid resuscitation. The sodium nadir occurred within 9 to 20 hours after DDAVP administration. No serious adverse events related to hyponatremia were recorded during the study period. CONCLUSIONS: The incidence of hyponatremia in children receiving DDAVP for prophylaxis of intraoperative bleeding following oropharyngeal surgery is high. The degree of hyponatremia is related to the perioperative fluid volume administered. A protocol for DDAVP administration, perioperative fluid resuscitation, and postoperative sodium monitoring that aims to reduce the incidence of hyponatremia in this population is proposed.
