Nonoperative management of blunt liver and spleen injury in children: evaluation of the ATOMAC guideline using GRADE

BACKGROUND: Nonoperative management of liver and spleen injury should be achievable for more than 95% of children. Large national studies continue to show that some regions fail to meet these benchmarks. Simultaneously, current guidelines recommend hospitalization for injury grade + 2 (in days). A new treatment algorithm, the ATOMAC guideline, is in clinical use at many centers but has not been prospectively validated. METHODS: A literature review conducted through MEDLINE identified publications after the American Pediatric Surgery Association guidelines using the search terms blunt liver trauma pediatric, blunt spleen trauma pediatric, and blunt abdominal trauma pediatric. Decision points in the new algorithm generated clinical questions, and GRADE [Grading of Recommendations, Assessment, Development, and Evaluations] methodology was used to assess the evidence supporting the guideline. RESULTS: The algorithm generated 27 clinical questions. The algorithm was supported by six 1A recommendations, two 1B recommendations, one 2B recommendation, eight 2C recommendations, and ten 2D recommendations. The 1A recommendations included management based on hemodynamic status rather than grade of injury, support for an abbreviated period of bed rest, transfusion thresholds of 7.0 g/dL, exclusion of peritonitis from a guideline, accounting for local resources and concurrent injuries in the management of children failing to stabilize, as well as the use of a guideline in patients with multiple injuries. The use of more than 40 mL/kg or 4 U of blood to define end points for the guideline, and discharging stable patients before 24 hours received 1B recommendations. CONCLUSION: The original American Pediatric Surgery Association guideline for pediatric blunt solid organ injury was instrumental in improving care, but sufficient evidence now exists for an updated management guideline.(AU)

Experience with FiberWire for pectus bar attachment.

BACKGROUND: Minimally invasive repair of pectus excavatum has become an established method for repair of pectus excavatum. Bar displacement or rotation remains the most common complication of this repair requiring return to the operating room. METHODS: Retrospective review of all patients at a single institution who underwent repair of pectus excavatum using FiberWire for bar stabilization between December 2009 and March 2013 was undertaken. RESULTS: 93 patients underwent minimally invasive pectus repair using FiberWire during the study period. The patients included 73 males and 20 females, with an average age of 14.6years (range 7-21years). Mean operative time was 102minutes (range 56-198minutes). No patients developed wound complications, two patients developed pain because of bar migration and required return to the OR, and no patients had recurrence of their pectus defect because of bar migration during the study period. Median length of follow-up was 17months (range 3-36months). CONCLUSION: Stabilization of pectus bars using circumferential rib fixation with FiberWire at multiple points on both sides of the bar appears to be effective in preventing bar rotation and displacement, and requires minimal change to the operation as it has been previously described. Early experience shows a low rate of complications.

Primary peritoneal drainage for increasing ventilatory requirements in critically ill neonates with necrotizing enterocolitis.

BACKGROUND/PURPOSE: Primary peritoneal drainage (PPD) is an established therapy for premature neonates with necrotizing enterocolitis (NEC) and free intraperitoneal air. This study seeks to evaluate the efficacy of PPD in ill premature neonates with severe abdominal distension and increasing ventilatory requirements without free intraperitoneal air. METHODS: Eleven neonates (gestational age, 27 +/- 0.59 weeks; age, 25 +/- 4.3 days; birth weight, 862 +/- 67 g) with NEC underwent bedside PPD under local anesthesia for rapid clinical deterioration characterized by severe abdominal distension and increasing ventilatory requirements. None showed radiographic evidence of free intraperitoneal air. Mean airway pressure (MAP) and oxygenation-index (OI) were analyzed 24 hours before, immediately before and 24 hours after surgery. The patients were followed up to discharge from hospital. Statistical analyses were performed using analysis of variance (ANOVA) for repeated measures. RESULTS: Mean airway pressure (MAP) showed a significant difference (P <.05) increasing from 7.1 +/- 0.75 cm H2O 24 hours before surgery to 11 +/- 1.3 cm H2O immediately before surgery and decreasing to 9.9 +/- 1.1 cm H2O 24 hours after drainage. Likewise, OI measured at the same time intervals showed significant differences (P <.05) deteriorating from 5 +/- 1.2 to 26 +/- 6.9 then improving to 13 +/- 3.5. A significant quadratic effect (P <.03) was evident for MAP and OI (ie, values significantly rose then fell). There were six 30-day survivors (55%), and 3 survived to discharge (27%). Of the long-term survivors, 2 required operative fistula closure, and 1 needed no further surgery. CONCLUSION: Bedside PPD for increasing ventilatory requirements and abdominal distension in critically ill neonates with nonperforated NEC is a simple technique that offers rapid stabilization, although ultimate mortality rate remains high.
