Complications in Pediatric Regional Anesthesia: An Analysis of More than 100,000 Blocks from the Pediatric Regional Anesthesia Network.

WHAT WE ALREADY KNOW ABOUT THIS TOPIC: WHAT THIS ARTICLE TELLS US THAT IS NEW: BACKGROUND:: Complications in pediatric regional anesthesia are rare, so a large sample size is necessary to quantify risk. The Pediatric Regional Anesthesia Network contains data on more than 100,000 blocks administered at more than 20 children's hospitals. This study analyzed the risk of major complications associated with regional anesthesia in children. METHODS: This is a prospective, observational study of routine clinical practice. Data were collected on every regional block placed by an anesthesiologist at participating institutions and were uploaded to a secure database. The data were audited at multiple points for accuracy. RESULTS: There were no permanent neurologic deficits reported (95% CI, 0 to 0.4:10,000). The risk of transient neurologic deficit was 2.4:10,000 (95% CI, 1.6 to 3.6:10,000) and was not different between peripheral and neuraxial blocks. The risk of severe local anesthetic systemic toxicity was 0.76:10,000 (95% CI, 0.3 to 1.6:10,000); the majority of cases occurred in infants. There was one epidural abscess reported (0.76:10,000, 95% CI, 0 to 4.8:10,000). The incidence of cutaneous infections was 0.5% (53:10,000, 95% CI, 43 to 64:10,000). There were no hematomas associated with neuraxial catheters (95% CI, 0 to 3.5:10,000), but one epidural hematoma occurred with a paravertebral catheter. No additional risk was observed with placing blocks under general anesthesia. The most common adverse events were benign catheter-related failures (4%). CONCLUSIONS: The data from this study demonstrate a level of safety in pediatric regional anesthesia that is comparable to adult practice and confirms the safety of placing blocks under general anesthesia in children.

Implementation of an enhanced recovery protocol in pediatric colorectal surgery.

PURPOSE: Enhanced recovery protocols (ERPs) have been shown to improve outcomes in adult surgical populations. Our purpose was to compare outcomes before and after implementation of an ERP in children undergoing elective colorectal surgery. METHODS: A pediatric-specific colorectal ERP was developed and implemented at a single center starting in January 2015. A retrospective review was performed including 43 patients in the pre-ERP period (2012-2014) and 36 patients in the post-ERP period (2015-2016). Outcomes of interest included number of ERP interventions received, length of stay (LOS), complications, and readmissions. RESULTS: The median number of ERP interventions received per patient increased from 5 to 11 from 2012 to 2016. The median LOS decreased from 5days to 3days in the post-ERP period (p=0.01). We observed a simultaneous decrease in median time to regular diet, mean dose of narcotics, and mean volume of intraoperative fluids (p<0.001). The complication rate (21% vs. 17%, p=0.85) and 30-day readmission rate (23% vs. 11%, p=0.63) were not significantly different in the pre- and post-ERP periods. CONCLUSIONS: Implementation of a pediatric-specific ERP in children undergoing colorectal surgery is feasible, safe and may lead to improved outcomes. Further experience may highlight other opportunities for increased compliance and improved care. LEVEL OF EVIDENCE: Treatment Study. Level III.

Pain-only complaint about cochlear implant device: A five-patient pediatric experience.

OBJECTIVES: To present the case histories and management of five pediatric patients who experienced pain at the receiver-stimulator site, but no other indication that the device was failing. Patients were from a sole-surgeon pediatric practice (600 + implant surgeries before June 2013; about even proportions of Advanced Bionics, Cochlear Corporation, and MED-EL devices). METHODS: The University Institutional Review Board-approved review of sole-surgeon pediatric case series. RESULTS: The onset of pain ranged from 2 to 16 years post implantation. Pain, not amenable to conventional medical therapy, was present regardless of whether or not the external appliance was 'on', or even being worn on the head. Four of the five patients were bilaterally implanted, but pain was only at one receiver-stimulator package. Clinical management ultimately included revision surgery in all five cases, with immediate resolution of the pain in four. For those four, the replacement cochlear implant (CI) performed well; the other patient fears pain if her replacement device is used, but continues enjoying her contralateral implant. At analysis by the company, two of five explanted devices exhibited problems: loss of hermeticity; insulation failure. DISCUSSION: Though infrequently reported, pain-only complaint by a CI user is a challenging dilemma. CONCLUSION: Pain may be the sole clinical manifestation of cochlear implant device failure. We offer a flowchart for the care of CI patients with pain, encourage a worldwide registry of such cases, and offer ideas to try to understand better the problem.

Risk and Resilience in Pediatric Chronic Pain: Exploring the Protective Role of Optimism.

OBJECTIVE: Fear of pain and pain catastrophizing are prominent risk factors for pediatric chronic pain-related maladjustment. Although resilience has largely been ignored in the pediatric pain literature, prior research suggests that optimism might benefit youth and can be learned. We applied an adult chronic pain risk-resilience model to examine the interplay of risk factors and optimism on functioning outcomes in youth with chronic pain. METHOD: Participants included 58 children and adolescents (8-17 years) attending a chronic pain clinic and their parents. Participants completed measures of fear of pain, pain catastrophizing, optimism, disability, and quality of life. RESULTS: Consistent with the literature, pain intensity, fear of pain, and catastrophizing predicted functioning. Optimism was a unique predictor of quality of life, and optimism contributed to better functioning by minimizing pain-related fear and catastrophizing. CONCLUSIONS: Optimism might be protective and offset the negative influence of fear of pain and catastrophizing on pain-related functioning.

Management of refractory pain in hospitalized adolescents with sickle cell disease: changing from intravenous opioids to continuous infusion epidural analgesia.

BACKGROUND: Prolonged hospitalizations for sickle cell disease painful episodes are not uncommon, as analgesic options are often suboptimal. OBSERVATIONS: Seven patients (15.4 ± 3.7 y, 6 females) were treated with epidural analgesia for refractory pain. The median duration of epidural catheter placement was 4 days (interquartile range, 3 to 6 d). Mean pain scores changed from 6.8 ± 2.7 to 4.8 ± 2.2, whereas mean daily parenteral opioid requirements changed from 79.7 ± 100.4 to 13.0 ± 13.1 mg of morphine equivalents. CONCLUSION: Continuous epidural analgesia is an alternative to continuing intravenous opioids in sickle cell disease patients with refractory pain, and may reduce opioid-related side effects and facilitate transition to oral analgesics.

Pediatric chronic orchalgia.

INTRODUCTION: Chronic orchalgia, defined as testicular pain lasting > 3 months and interfering with normal activities, is neglected in the pediatric literature. We describe our experience with the evaluation and treatment of pediatric chronic orchalgia patients. MATERIALS AND METHODS: Charts were screened to identify patients meeting the criteria for chronic orchalgia. Charts were further reviewed to record the history and physical exam, diagnostic tests, treatment and outcomes. RESULTS: 65/982 patients met the criteria for chronic orchalgia. Mean age was 13 and mean duration of pain was 8.6 months. Physical exam findings were normal in 46 patients (70%). 59 patients were managed conservatively with resolution (10/59, 17%) or a single visit (36/59, 61%) in 78%. 13/59 (22%) patients showed either minor improvement or no change in symptoms. 5 non-responding patients were managed by the anesthesia pain service; 4 received epidurals with or without additional oral pain medications with 3 experiencing significant pain improvement. CONCLUSION: Conservative management of chronic orchalgia allowed symptoms to subside in the majority of cases. We recommend patients be treated with conservative measures for 1-2 months. If this fails, early involvement of the anesthesia pain service can offer treatment modalities such as epidural analgesia. Surgical management in the face of a normal physical exam does not seem to have a role.
