Intraoperative high-dose epinephrine infiltration in cleft palate repair.

OBJECTIVE: Local infiltration of epinephrine before surgical procedures is a well-accepted technique to promote vasoconstriction. Typically, the dose of epinephrine is limited by the co-administration of local anesthetic as well as the risk for arrhythmogenesis and hemodynamic changes. In addition, some controversy exists regarding the acceptable dose of epinephrine given to children. This retrospective review examines the use and safety of "high-dose" epinephrine in palatoplasty at our cleft-craniofacial center. DESIGN: A retrospective review of epinephrine use in primary palatoplasty at a tertiary children's hospital from 2003 to 2007 was performed. Operative and anesthetic records were reviewed for hypertension (systolic blood pressure, >120 or diastolic blood pressure, >70) and tachycardia (>190 beats per min) as defined by the American Heart Association guidelines, as well as dysrhythmias, intraoperative complications, and postoperative complications. RESULTS: A total of 102 patients who underwent consecutive primary palatoplasties performed by a single surgeon were identified. After the induction of anesthesia and before incision, the patients received an initial epinephrine infiltration (without local anesthetic) up to a maximum 10 µg/kg. The average total dose of epinephrine administered during palatoplasty was 12.8 µg/kg (range, 3.2-75.0 µg/kg). Doses up to a maximum of 10 µg/kg were administered as needed at 30-minute intervals. No instances of clinically unstable tachycardia or hypertension occurred. A total of 21.6% of the patients (22/102) experienced an instance of hypertension, and only 13.7% of these (14/102) were related to epinephrine administration. One (1%) postoperative fistula was identified. CONCLUSIONS: Locally infiltrated high-dose epinephrine during palatoplasty can be safely used as a means of vasoconstriction. Doses reaching a maximum of 10 µg/kg, administered as needed at 30-minute intervals, do not seem to be a significant risk for hemodynamic instability, intraoperative complications, or postoperative complications.

Perioperative management of children undergoing craniofacial reconstruction surgery: a practice survey.

OBJECTIVE/AIMS: To assess current practices in the management of children undergoing craniofacial surgery and identify areas of significant practice variability with the intent to direct future research. BACKGROUND: The perioperative management of infants and children undergoing craniofacial reconstruction surgery can be challenging because of the routine occurrence of significant blood loss with associated morbidity. A variety of techniques have been described to improve the care for these children. It is presently unknown to what extent these practices are currently employed. METHODS: A web-based survey was sent to representatives from 102 institutions. One individual per institution was surveyed to prevent larger institutions from being over-represented in the results. RESULTS: Requests to complete the survey were sent to 102 institutions; 48 surveys were completed. The survey was composed of two parts: management of infants undergoing strip craniectomies, and management of children undergoing major craniofacial reconstruction. CONCLUSIONS: Significant variability exists in the management of children undergoing these procedures; further study is required to determine the optimal management strategies. Clinical trials assessing the utility of central venous pressure and other hemodynamic monitoring modalities would enable evidence-based decision-making for monitoring in these children. The development of institutional transfusion thresholds should be encouraged, as there exists a body of evidence supporting their efficacy and safety.
