Pain Management in Pectus Excavatum Surgery: A Comparison of Subcutaneous Catheters Versus Epidurals in a Pediatric Population.

BACKGROUND: Pectus excavatum is a common chest wall anomaly. Achieving optimal pain control is a priority for adolescents undergoing surgical correction of this condition. Options for pain control include the use of subcutaneous catheters (On-Q® pumps) and epidurals. The objective of this study is to demonstrate the feasibility of using subcutaneous catheters for pain control and to compare them with the use of epidurals during surgical correction of pectus excavatum. MATERIALS AND METHODS: We identified patients who underwent pectus excavatum repair at our institution between January 2010 and August 2016. Patients were divided into two cohorts (epidural or On-Q pump). Patient charts were reviewed for length of stay, pain scores, pain medications, and complications. RESULTS: A total of 124 patients were included. Forty percent of patients used an epidural (n = 50), and 60% had the On-Q pump (n = 74). The average patient age was 15.6 years. The average Haller index was 4.3. The On-Q pump population had a significant decrease in postoperative length of stay (mean [M] = 4.86, standard deviation [SD] = 0.85) compared with the epidural population (M = 5.60, SD = 0.97); P ≤ .001. There was a significant difference observed in pain scores for patients on the epidural (M = 2.91, SD = 1.13) and On-Q pump (M = 3.81, SD = 1.19; P ≤ .001). There was n = 1 wound infection in each group. CONCLUSION: The use of bilateral subcutaneous infusion catheters is a safe and effective method for pain control in patients undergoing surgical correction of pectus excavatum. Even though the degree of pain control is not necessarily superior to epidurals, in this study, the catheters were associated with a shorter postoperative length of stay in this patient population and did not increase the incidence of complications.

Postoperative Pain Outcomes After Nuss Procedures: Comparison of Epidural Analgesia, Continuous Infusion of Local Anesthetic, and Preoperative Self-Hypnosis Training.

BACKGROUND/PURPOSE: The Nuss procedure to correct pectus excavatum is associated with severe postoperative pain. The purpose of this retrospective study was to compare pain management outcomes of thoracic epidural analgesia and continuous infusion of local anesthetic (CILA) with and without preoperative self-hypnosis training (SHT) after Nuss procedure (4 treatment groups). METHODS: Between February 2010 and December 2013, 24 of 53 adolescents who underwent Nuss procedure received SHT. Of these, 16 received thoracic epidural analgesia and 8 received CILA postoperatively. Of the 29 patients who did not receive SHT, 19 received thoracic epidural analgesia and 10 received CILA. All patients received intravenous patient-controlled opioid analgesia and intravenous nonsteroidal anti-inflammatory drugs (IVNSAIDs) and then were transitioned to oral opioids and NSAIDs. Postoperative mean and maximum pain scores, opioid (morphine equivalents) use and side effects, and hospital length of stay (LOS) were compared between groups. RESULTS: Patients who received SHT reported lower mean (P = .0047) and maximum (P = .0028) pain scores and used less morphine equivalents/hour over time (P = .046) compared to patients who did not receive SHT. Patients who received thoracic epidural analgesia reported lower mean (P = .0092) and maximum (P = .0083) postoperative pain scores and used more morphine equivalents/hour (P = .01) compared to those who received CILA. In addition, patients who received SHT and CILA had shorter LOS (P = .0013) than patients who received thoracic epidural analgesia without SHT. CONCLUSIONS: SHT before pectus excavatum repair by Nuss procedure results in less postoperative pain and requires less morphine equivalents over time for postoperative pain management. Opioid-sparing CILA, when paired with SHT, results in shorter LOS.

Pectus Carinatum: Factors That Contribute to Success and Failure of Nonoperative Treatment.

BACKGROUND: Pectus carinatum is a congenital chest wall deformity characterized by protrusion ofthe sternum and ribs. External bracing has been the gold standard treatment for this condition for the past 20 years. PURPOSE: The primary purpose of the study was to identify factors that contribute to treatment success of bracing for patients with pectus carinatum. The secondary aim was to identify the optimal age to recommend bracing for pectus carinatum. METHODS: 176 patients who were evaluated for a brace for pectus carinatum were contacted to participate in an online survey about their experience. A retrospective chart review was conducted on patients who participated in the survey. RESULTS: Subjects rated themselves as more confident afterbracing(P=.002). Patients who hadfamily sup- port, and no documented complaints (P = .024) and (P = .009) respectively, were more likely to say they had made the right choice to wear the brace. CONCLUSIONS: This study demonstrated that family support and fewer complaints are predictors of success for the brace.

Efficacy of Analgesic Treatments to Manage Children's Postoperative Pain After Laparoscopic Appendectomy: Retrospective Medical Record Review.

Knowledge of the effectiveness of multimodal analgesic treatments to manage children's postoperative pain during hospital stays is limited. Our retrospective chart review of a convenience sample of 200 pediatric surgical patients' pain experiences during the first 24 hours after laparoscopic appendectomy demonstrates the benefits of a multimodal analgesic approach. We found that pediatric patients who received perioperative IV ketorolac in addition to opioids reported statistically significantly lower mean pain intensity (n = 134, mean [M] = 2.9, standard deviation [SD] = 1.7) during the first 24 hours after surgery when compared with the pain intensity of patients who did not receive perioperative IV ketorolac (n = 66, M = 3.7, SD = 1.7, t = 3.14, P = .002). Patients who received perioperative IV ketorolac (M = 0.94, SD = 0.71) also received significantly fewer morphine equivalents of postoperative opioids during the first 24 hours after surgery than those who did not (M = 1.21, SD = 0.78, t = 2.41, P = .02). We will use data from these patients to introduce the potential for a personalized medicine approach to postoperative pain.

Current trends in the surgical treatment of pediatric ovarian torsion: we can do better.

INTRODUCTION: Current literature strongly recommends ovarian preservation for pediatric patients with ovarian torsion. The purpose of this study was to evaluate national trends in the surgical management of pediatric ovarian torsion and to compare outcomes between pediatric surgeons (PED) and gynecologists (GYN). METHODS: We queried Pediatric Health Information System (PHIS) data from 2007 to 2011 for patients <18years old with a diagnosis of ovarian torsion who underwent a surgical procedure. Patients with malignant disease were excluded. Outcomes were compared between pediatric surgeons and gynecologists. RESULTS: A total of 1151 patients were identified with a mean age of 10.7±4.1years with a bimodal distribution. Pediatric surgeons performed the majority of procedures (81%) and were more likely to use a laparoscopic approach (PED 27% vs. GYN 17%, p<.05). Pediatric surgeons were more likely to perform an oophorectomy (PED 38% vs. GYN 27%, p<.01), and more likely to administer antibiotics for this clean procedure (PED 61% vs. GYN 29%, p<.001). The overall reoperation rate was 5.1% and did not differ significantly by subspecialty (PED 4.4% vs. GYN 7.8%, p>.05). CONCLUSIONS: These data demonstrate a significant opportunity for pediatric surgeons and gynecologists to improve ovarian salvage rates and to reduce unnecessary antibiotic utilization for children with ovarian torsion.

Improving surgical residents' performance on written assessments of cultural competency.

CONTEXT: The pressure to implement cultural-competency training at the level of GME is high. The rapidly diversifying American population and the ACGME demand it, and cultural competency is recognized as a core competency under "Professionalism." OBJECTIVES: The objectives for this study were (1) to assess residents' baseline levels of cultural competence, (2) define barriers to skill-acquisition, and (3) examine efficacy of educational programs in improving cultural competence. SETTING & PARTICIPANTS: In all, 43 residents from the University of Connecticut School of Medicine participated in a prospective, Institutional Review Board (IRB)-approved study. DESIGN: During Step 1 (pretest), baseline performance was recorded using 3 assessments: (1) Healthcare Cultural Competency Test (HCCT), (2) Cultural skills acquisition (CSA), and (3) Clinical Scenarios Test (CSE). During Step 2 (Educational Intervention), a 2-part lecture that focused on principles of cultural competency and continued self-learning was presented. Last, for Step 3 (posttest), the post-program evaluation was administered as in Step 1. MAIN OUTCOME MEASURES: Answers for Step 1 (pretest) and Step 3 (posttest) were compared using a paired t-test for HCCT and CSE and the chi-square test for CSA. RESULTS: Thirty-five replies were evaluated. Every resident performed better on the posttest than the pretest. Specifically, participants showed 88% improvement in their scores on the HCCT (pretest: 360, posttest: 696; p < 0.01), 2-fold improvement on the CSA (pretest: 6, posttest: 12; p < 0.009), and 40% improvement in CSE (pretest mean score = 23.3, posttest = 34.6; p < 0.01). Commonly identified barriers to learning included inadequate teaching tools and absence of formal training. CONCLUSIONS: Surgery residents tested for 3 aspects of cultural competence prior to and after teaching sessions showed marked improvement on all 3 assessment measures after this brief intervention.

Epulis gravidarum manum: pyogenic granuloma of the hand occurring in pregnant women.

Pyogenic granuloma, also known as lobular capillary hemangioma, is a benign vascular tumor of the skin and mucous membranes. Whereas the literature describes pyogenic granulomas of pregnancy as occurring mainly within the gingival or oral mucosa, we present 5 cases of a histologically confirmed pyogenic granuloma on the hands of gravid women, each with no history of antecedent trauma. These tumors failed to resolve spontaneously postpartum necessitating surgical removal. We propose the term epulis gravidarum manum to describe this skin lesion.

Giant lipomas of the upper extremity.

Lipomas are slow-growing soft tissue tumours that rarely reach a size larger than 2 cm. Lesions larger than 5 cm, so-called giant lipomas, can occur anywhere in the body but are seldom found in the upper extremities. The authors present their experiences with eight patients having giant lipomas of the upper extremity. In addition, a review of the literature, and a discussion of the appropriate evaluation and management are included.

Cardiac conduction through engineered tissue.

In children, interruption of cardiac atrioventricular (AV) electrical conduction can result from congenital defects, surgical interventions, and maternal autoimmune diseases during pregnancy. Complete AV conduction block is typically treated by implanting an electronic pacemaker device, although long-term pacing therapy in pediatric patients has significant complications. As a first step toward developing a substitute treatment, we implanted engineered tissue constructs in rat hearts to create an alternative AV conduction pathway. We found that skeletal muscle-derived cells in the constructs exhibited sustained electrical coupling through persistent expression and function of gap junction proteins. Using fluorescence in situ hybridization and polymerase chain reaction analyses, myogenic cells in the constructs were shown to survive in the AV groove of implanted hearts for the duration of the animal's natural life. Perfusion of hearts with fluorescently labeled lec-tin demonstrated that implanted tissues became vascularized and immunostaining verified the presence of proteins important in electromechanical integration of myogenic cells with surrounding re-cipient rat cardiomyocytes. Finally, using optical mapping and electrophysiological analyses, we provide evidence of permanent AV conduction through the implant in one-third of recipient animals. Our experiments provide a proof-of-principle that engineered tissue constructs can function as an electrical conduit and, ultimately, may offer a substitute treatment to conventional pacing therapy.
