Official title: The Effect of Methadone vs. Fentanyl Administration on Postoperative Pain Control in Pediatric Patients Undergoing Cardiac Surgery: A Randomized, Double-Blinded Controlled Trial

Status Terminated

Clinical Trial Summary

The purpose of this study is to determine if methadone improves postoperative pain control in pediatric patient's undergoing cardiac surgery.

Clinical Trial Description

The proposed study will be conducted at Children's National Health System (CNHS). Pediatric subjects undergoing cardiac surgery requiring cardiopulmonary bypass will be recruited. Eligible and consenting participants will be assigned a unique identification number and will be randomly assigned to receive either methadone or fentanyl using a computer-generated randomization scheme. A total of 52 participants will be enrolled to each arm of the study, providing 80% power to detect a 30% difference between groups. Once informed consent is obtained the inpatient pharmacist at CNHS will randomly assign eligible participants to receive methadone or fentanyl. The pharmacist will prepare 0.3 mcg/kg of methadone and 20 mcg/kg of fentanyl for loading dose administration, diluted to 10 mL. The IDS pharmacy will store and maintain all medications per Department of Pharmacy standard operating procedures for waste of a controlled substance (C-II) drug. The treatment phase will begin at the induction of general anesthesia and finish at the end of the surgical procedure. Standard anesthetic practice for monitoring, induction, and maintenance of general anesthesia will be preserved throughout. Participants will receive either 0.3 mg/kg of methadone or 20 mcg/kg of fentanyl prior to surgical incision, over 20 minutes. The medication will be prepared as described above and all research and staff personnel as well as the study participant will be blinded to treatment group assignment. As per standard anesthetic practice, the subject will continue to be evaluated for hemodynamic stability, postoperative risk of bleeding, and respiratory effort. Morphine at 0.05 mg/kg per dose will be administered intravenously as needed for pain control. Surgical procedures and times will be recorded in the operative report via the electronic medical record. Postoperative ICU Phase The postoperative cardiac intensive care unit phase will begin at admission to the Cardiac Intensive Care Unit (CICU) and will end on the third day of hospital admission. Postoperative care including hemodynamic stability, resuscitation, and respiratory support will be at the discretion of the CICU team. As per CICU protocol, the nurse will monitor and record vital signs and pain scale (FLACC) scores beginning at handoff from the anesthesia team to the intensive care team. The nurse will continue to document vital signs including: blood pressure, heart rate, respiratory rate, oxygen saturation, temperature, minute ventilation when mechanically ventilated, and oxygen supplementation when appropriate, in the electronic medical record every hour. As per nursing protocol, FLACC scores will be recorded in the electronic medical record every 4 hours or when the nursing staff witnesses pain during the entirety of the subject's CICU stay. All subjects will receive analgesics and sedation medication based on CICU postoperative pain control and agitation protocol Data Collection The investigator or designee, blinded to group assignment, will collect all of the relevant data from the electronic medical record within six months of the cardiac surgery and enter it into the Medical Center's proprietary web-based data-entry and data-management system, REDcap (Research Electronic Data Capture). The source of information will be medical records at the Children's National Health System "Anesthesiology" and "Bear Tracks" information systems provided by Cerner Corporation. Data will be obtained specifically for research purposes. Subject identifiers (e.g. name, date of birth, address) will not be entered into the REDcap system. The previously assigned unique identification numbers will be used. Statistical Considerations Significance will be measured as a 30% reduction in postoperative pain requirement. Statistical analysis will be used to evaluate any differences between the randomization groups in opioid-related adverse events during the first 24-hour postoperative period. ;
