Multimodal anesthesia with the addition of methadone is superior to epidural analgesia: A retrospective comparison of intraoperative anesthetic techniques and pain management for 124 pediatric patients undergoing the Nuss procedure.

BACKGROUND: The Nuss procedure corrects pectus excavatum by forceful displacement of the sternum with metal bars. Optimal pain management remains a challenge. Mutimodal anesthesia alleviates pain through blockade of multiple nociceptive and inflammatory pain receptors. METHODS: A retrospective chart review of anesthetic and postoperative mangement of 125 children undergoing the Nuss procedure was conducted. Anesthetic mangement strategies were analyzed in four groups: opioid during general anesthesia (GA), epidural with general anesthesia (Epidural), multimodal anesthesia (MM), and multimodal anesthesia with methadone (MM+M). Data collection included total opioid use (as equivalent milligrams of morphine (Mmg)), pain scores, length of stay (LOS), and adverse effects. RESULTS: Total opioid use varied by group (median, IQR (in Mg)): Epidural 213 [149, 293], GA 179 [134, 298], MM (150 [123, 281]), and MM+M (106 [87, 149]), as did severe pain (in minutes): Epidural (208 [73, 323]), GA (115 [7, 255]), MM (54 [0, 210]), and MM+M (49 [0, 151]). LOS was shortest for the MM+M group (MM+M=3.8+1.0days; MM=4.5+1.3days; GA=4.9+1.4days, Epidural=5.5+2.3days). CONCLUSION: Multimodal anesthesia is associated with less postoperative pain and shorter LOS compared to epidural or traditional anesthetic techniques for the Nuss procedure. Multimodal anesthesia with a single intraoperative dose of methadone was associated with lowest total opioid use, time with uncontrolled pain, and shortest LOS.

Evaluation of dexmedetomidine and postoperative pain management in patients with adolescent idiopathic scoliosis: conclusions based on a retrospective study at a tertiary pediatric hospital.

OBJECTIVES: This study evaluated the effectiveness of dexmedetomidine in decreasing opioid use in children with adolescent idiopathic scoliosis following posterior spinal fusion surgery at a pediatric tertiary care hospital over the past 10 years. DESIGN: This was a retrospective chart review. Patients were separated into two groups: those that received opioid via patient-controlled analgesia pain therapy alone and those that received opioid via patient-controlled analgesia pain therapy with dexmedetomidine. SETTING: A tertiary pediatric free-standing hospital. The study focused on care administered in the perioperative period, including the operating room, ICU, and general hospital floor. PATIENTS: One hundred sixty-three children with adolescent idiopathic scoliosis. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Measurements included patient demographics, American Society of Anesthesiologists Physical Status Classification System, levels of spinal fusion, length of hospital stay, complications, numeric pain scores, opioid requirement, elastomeric pain pump use, length of time until ambulation, adverse effects, and naloxone use. Data were collected through the first 72 hours of the perioperative period. One hundred six patients received opioids via patient-controlled analgesia therapy with dexmedetomidine and 57 received opioids via patient-controlled analgesia alone. Within the groups, there were 46 patients who received local anesthetic infusions via elastomeric pumps in the patient-controlled analgesia with dexmedetomidine group and 16 patients had pumps in the patient-controlled analgesia-alone group. There was no overall difference in postoperative use of morphine (or equivalents) between the two groups. However, the use of elastomeric pain pumps demonstrated a statistically significant decrease in mean overall opioid consumption (42.6 mg vs 63.1 mg, p < 0.001). CONCLUSIONS: There was no difference in opioid use related to dexmedetomidine on any postoperative day. The only variable showing a significant opioid sparing effect was the use of local anesthetic infusions via elastomeric pumps. Using continuous local anesthetic infusions instead of dexmedetomidine could eliminate the need for ICU admission, require shorter hospital stays, and reduce costs while still providing safe and effective pain control.

Proton beam radiation therapy in the treatment of pediatric central nervous system malignancies: a review of the literature.

One of 5 pediatric cancers occurs within the central nervous system. Although outcomes have improved, the greatest challenge with these patients remains the balance between cure and long-term morbidity. Patients who have undergone radiation therapy remain at high risk for developing a multitude of severe long-term sequelae. As radiation therapy remains a mainstay of treatment much attention has gone into improving its quality and precision. Multiple options exist for these patients, including conventional photon radiotherapy, conformal radiation, and now, proton beam radiotherapy. Proton beams are able to provide utmost precision for targeting the site of the tumor while decreasing radiation doses to surrounding tissues. Studies are showing that the benefits of proton therapy surpass both conventional radiation as well as conformal radiation therapy, and as a result medical centers around the United States are working to open more facilities and improve patient access. As research becomes more readily available and new centers open, pediatric patients will have the option to be treated with this technology in order to preserve cognitive function and decrease long-term effects.
