The relationship between intraoperative fluid management and postoperative adverse outcome in a orthognathic surgery

ABSTRACT

patient management generate more controversy than that of appropriate fluid and electrolyte therapy. especially, controversy has swirled around colloid vs crystalloid therapy and the composition of administered fluids, agreement among clinicians as to what fluid therapy is appropriate, and in what amount, is rare. This controversy likely will be enhanced by Arieff's provocative article. He described 11 adult, and 2 pediatric patients. All developed fatal postoperative pulmonary edema, seemingly caused solely by excessive postoperative fluid administration. From January 1999. to December 1999, we investigated 24 patients, which were operated by orthognathic surgery, about the intraoperative fluid therapy and the associated effect in orthognathic surgery, which is regarded as one of the major surgery of oral and maxillofacial surgery. First, They were devided into two groups, that is one-jaw surgery and two-jaw surgery, and each groups were devided by intraoperative fluid volume of 8ml/kg/hr. Subjective assesment was collected through use of a series of 3 questionnaries. In each questionnaire, a 5-point Liekert scale was used for assessment of following parameters of recovery from anesthesia headache, dizziness, drowsiness, nausea/vomiting, thirst. The patient completed questionnaire 1 at 4 hour after surgery, questionnaire 2 was completed at 24 hours after surgery, and questionnaire 3 was completed at 48 hours after surgery. This study demonstrated that appropriated perioperative rehydration decreases postoperative adverse outcomes and improved the patient's perception of the postoperative period. fluid, orthognathic surgery, complication.
