Incorporating a Trauma-Informed Care Protocol Into Pediatric Trauma Evaluation: The Pediatric PAUSE Does Not Delay Imaging or Disposition.

OBJECTIVES: Trauma evaluation in the emergency department (ED) can be a stressful event for children. With the goal of minimizing pain, anxiety, and unneeded interventions in stable patients, we implemented the Pediatric PAUSE at our level 1 adult/level 2 pediatric trauma center. The Pediatric PAUSE is a brief protocol performed after the primary survey, which addresses Pain/Privacy, Anxiety/IV Access, Urinary Catheter/Rectal exam/Genital exam, Support from family or staff, and Explain to patient/Engage with PICU team. The aim was to assess whether performing the PAUSE interfered with timeliness of emergent imaging in pediatric patients and their disposition. METHODS: We identified all patients aged 0 to 18 years evaluated as trauma activations at our institution after the Pediatric PAUSE was implemented (October 1, 2016-March 31, 2017) as well as 2 analogous 6-month pre-PAUSE periods. Patient demographics, time to imaging studies, and time to ED disposition were analyzed. RESULTS: One hundred seventy-two patients met the study criteria, with a mean age of 10.9 years and mean injury severity score of 10.6. One hundred fifteen participants (68.5%) were transferred from other hospitals, and 101 (87.8%) had ≥1 imaging study performed before arrival. The Pediatric PAUSE was performed for 41 (25%) of 163 study participants. There was no difference in time to first imaging study in participants for whom the PAUSE was performed (18.4 vs 15.0 minutes, P = 0.09). CONCLUSIONS: The PAUSE is a practice intervention designed to address the psychosocial needs of pediatric trauma patients and their families to help prevent posttraumatic stress symptoms. Implementation did not interfere with the timeliness of first imaging in pediatric trauma patients.

CT-guided blood tattoo for thoracoscopic excision of lung lesions in pediatric patients.

BACKGROUND: To describe a single-institutional experience with an innovative technique using CT-guided injection of autologous blood for localization of nonpleural-based pulmonary nodules prior to thoracoscopic excisional biopsy in pediatric patients. METHODS: A retrospective review of all patients under the age of 18 with lung lesions suspected to be malignant that were not pleural-based lesions and were not of adequate size to visualize at thoracoscopy, who underwent CT-guided blood tattoo (CGBT) localization between 2006-2019. CGBT was performed under general anesthesia by injecting 0.5-10 mL of autologous blood into the area of the lesions. The patients were then immediately transferred from interventional radiology to the operating room for thoracoscopic excision of the lesion. Demographics, location of lesions, indication for biopsy, and pathology were reviewed. RESULTS: In eleven pediatric patients (ages ranging from 4-18 years), preoperative CGBT localization of pulmonary nodules resulted in successful thoracoscopic excisional biopsy. All resections were diagnostic and 82% (9/11 cases) represented a metastatic malignancy as confirmed by pathology. Malignant nodules ranged from 2 to 14 mm in size, while a 13 mm nodule in a patient with history of AML was determined to be an organizing pneumonia and a 12 mm nodule in a second patient revealed a caseating granuloma consistent with Crohn's disease. One patient with a failed attempt at excisional biopsy without preoperative localization then underwent CGBT one week later with successful thoracoscopic excision of the nodule. CONCLUSIONS: CT-guided blood tattoo is a safe option for localization of nonpleural-based lung nodules prior to thoracoscopic excision in pediatric patients.

Advanced providers in pediatric surgery: Evaluation of role and perceived impact.

INTRODUCTION: The shortage of medical doctors in certain geographies and certain disciplines, resident work hour limitations and the demonstrated positive impact of advanced providers (nurse practitioners, physician assistants and clinical nurse specialists) on the quality and efficiency of care in numerous specialties have led to broader integration of advanced providers in healthcare organizations. With regard to pediatric surgery, some tertiary centers have successfully implemented 24/7 nurse practitioner coverage for their inpatient services. However, pediatric surgery practices vary throughout North America and the broader presence and function of advanced providers among all practice types and settings has not been characterized previously. The purpose of this survey is to conduct a descriptive evaluation of current pediatric surgical practices in North America with regard to advanced provider coverage and their perceived impact on care delivery and patient satisfaction. METHODS: A 14-item online survey, approved by the American Pediatric Surgical Association (APSA) Outcomes and Evidence-Based Practice Committee, was distributed to all full APSA members (N = 1189, opening rate of 56%), representing the vast majority of pediatric surgeons in North America. The survey investigated the practice characteristics of the responding surgeon, the presence and role of advanced providers in their practice and their perceived impact on patient care. Descriptive statistics were performed to characterize the function of advanced providers in pediatric surgery practices. Further analysis was performed to assess for geographic differences in staffing practices using United States Census Divisions. RESULTS: A total of 266 pediatric surgeons completed the survey (response rate 22% and 40% considering "email send out" and "email opening" rates respectively), with 47.6% employed at free standing children's hospitals and 41.1% employed at a children's hospital within an adult hospital. Nearly all respondents (N = 244, 91.7%) reported the presence of advanced providers in their practice with nurse practitioners (N = 216) and physician assistants (N = 101) most commonly represented. The majority of advanced providers (N = 189, 77.8%) covered both general surgery and trauma patients. Advanced providers worked nearly equally in the outpatient (N = 219, 89.8%) and inpatient setting (N = 232, 95.1%), though less often in the neonatal (N = 131) or pediatric (N = 126) intensive care unit. Fifteen percent of surgeons (N = 40) reported that advanced providers provided 24/7 coverage within their surgical practice. Surgeons reported that advanced providers had a very positive (75%) or positive (21%) impact on their clinical practice, with none reporting a negative impact. Surgeons also reported that advanced providers had a very positive (74%) or positive (21%) impact on perceived patient satisfaction. The main area in which surgeons reported the most significant impact of associate providers was continuity of care (N = 77), efficiency of service (N = 66) and education of parents and patients (N = 53). CONCLUSION: Pediatric surgical practices of all types are broadly utilizing advanced providers. Surgeons report that the integration of advanced providers across inpatient and outpatient settings has positively impacted care, advancing both continuity of care and efficiency of service. Advanced providers likely represent part of the solution to delivering quality care in current delivery systems. STUDY TYPE: Prospective Study/ Survey LEVEL OF EVIDENCE: IV.

Scleromatous Changes in an Abdominal Wall Graft: Graft-Versus-Graft Disease, or Chronic Graft Rejection?

Abdominal wall transplants are relatively new procedures that are frequently performed in conjunction with multivisceral transplants. The skin of the abdominal wall transplant is often the first site for graft rejection to manifest itself. Prompt recognition can lead to appropriate treatment before the involvement of the underlying viscera. However, the signs of graft rejection are nonspecific and can overlap with other entities. We present a case of a patient who received a multivisceral and abdominal wall transplant from 2 different donors, who presented with acute and eventually chronic graft rejection of the abdominal wall graft. Serial biopsies performed during the course of her treatment demonstrated progressive sclerotic changes in the dermis. Because these changes were confined to the abdominal wall graft, they could represent either chronic graft rejection or graft-versus-graft disease. To date, graft-versus-graft disease has not been documented in these patients. This case illustrates the possibility that patients with multidonor transplants may be at an increased risk for graft failure secondary to multiple potential etiologies.

Timing of bariatric surgery for severely obese adolescents: a Markov decision-analysis.

PURPOSE: Although controversial, bariatric surgery is increasingly being performed in adolescents. We developed a model to simulate the effect of timing of gastric bypass in obese adolescents on quantity and quality of life. METHODS: A Markov state-transition model was constructed comparing two treatment strategies: gastric bypass surgery at age 16 versus delayed surgery in adulthood. The model simulated a hypothetical cohort of adolescents with body mass index of 45kg/m(2). Model inputs were derived from current literature. The main outcome measure was quality and quantity of life, measured using quality-adjusted life-years (QALYs). RESULTS: For females, early gastric bypass surgery was favored by 2.02 QALYs compared to delaying surgery until age 35 (48.91 vs. 46.89 QALYs). The benefit was even greater for males, where early surgery was favored by 2.9 QALYs (48.30 vs. 45.40 QALYs). The absolute benefit of surgery at age 16 increased; the later surgery was delayed into adulthood. Sensitivity analyses demonstrated that adult surgery was favored only when the values for adverse events were unrealistically high. CONCLUSIONS: In our model, early gastric bypass in obese adolescents improved both quality and quantity of life. These findings are useful for surgeons and pediatricians when counseling adolescents considering weight loss surgery.

Epidural analgesia versus intravenous patient-controlled analgesia following minimally invasive pectus excavatum repair: a systematic review and meta-analysis.

BACKGROUND/PURPOSE: The minimally invasive pectus excavatum repair (MIPER) is a painful procedure. The ideal approach to postoperative analgesia is debated. We performed a systematic review and meta-analysis to assess the efficacy and safety of epidural analgesia compared to intravenous Patient Controlled Analgesia (PCA) following MIPER. METHODS: We searched MEDLINE (1946-2012) and the Cochrane Library (inception-2012) for randomized controlled trials (RCT) and cohort studies comparing epidural analgesia to PCA for postoperative pain management in children following MIPER. We calculated weighted mean differences (WMD) for numeric pain scores and summarized secondary outcomes qualitatively. RESULTS: Of 699 studies, 3 RCTs and 3 retrospective cohorts met inclusion criteria. Compared to PCA, mean pain scores were modestly lower with epidural immediately (WMD -1.04, 95% CI -2.11 to 0.03, p=0.06), 12 hours (WMD -1.12; 95% CI -1.61 to -0.62, p<0.001), 24 hours (WMD -0.51, 95%CI -1.05 to 0.02, p=0.06), and 48 hours (WMD -0.85, 95% CI -1.62 to -0.07, p=0.03) after surgery. We found no statistically significant differences between secondary outcomes. CONCLUSIONS: Epidural analgesia may provide superior pain control but was comparable with PCA for secondary outcomes. Better designed studies are needed. Currently the analgesic technique should be based on patient preference and institutional resources.

Case report: Crossed testicular ectopia.

Crossed testicular ectopia is a rare congenital anomaly in which both testes descend through a single inguinal canal. The typical presentation is that of ipsilateral inguinal hernia and contralateral cryptorchidism. This is a case report of crossed testicular ectopia in a 6-month-old male infant with depiction of herniorrhaphy and laparoscopic intraabdominal findings.

Classification of the dysmorphology of pectus excavatum.

BACKGROUND/PURPOSE: To describe the dysmorphology of pectus excavatum, the most common congenital chest wall anomaly. METHODS: A stratified sample of 64 patients, representative of a patient population with pectus excavatum of the Children's Hospital of King's Daughters in Norfolk, VA, was described and classified. The sample was stratified by sex to represent a 4:1 male-to-female ratio. The sample was further stratified to represent categories of age (3-10, 11-16, and 17 years and older). Preoperative photos and baseline chest computed tomography scans were examined and categorized according to the chief criteria, including asymmetry/symmetry of the depression, localized vs diffuse morphology, sternal torsion, cause of asymmetric appearance, and the length of the depression. RESULTS: Useful morphologic distinctions in pectus excavatum are localized depressions vs diffuse depressions, short and long length, symmetry, sternal torsion, slope/position of absolute depth, and unique patterns such as the horns of steer depression. CONCLUSIONS: These classifications simplify the diagnosis of pectus excavatum, aid in corrective surgery, and should improve correlation of phenotype and genotype in future genetic analysis.

Reliability of a standardized protocol to calculate cross-sectional chest area and severity indices to evaluate pectus excavatum.

PURPOSE: In evaluating the impact of surgical repair of pectus excavatum, the Haller index developed for preoperative decision-making purposes may be inadequate to quantify postoperative changes in shape of the chest. Individual patients may also have chest characteristics that impact the success of repair, many of which would be unlikely to be measured by the Haller index alone. We have developed a protocol that measures the cross-sectional chest area and the asymmetry index along with the Haller index to more completely quantify the nature of the deformity. The purpose of this study was to determine the reliability of this protocol in the interpretation of chest computed tomography images from multiple sites. The protocol was developed as part of a multicenter study of clinical outcomes after surgical repair of pectus excavatum. METHODS: Two radiologists independently selected 5 images from each of 32 computed tomography scans from multicenter study participants according to the protocol. A digitizer was used to measure the diameters and cross-sectional areas of the images selected; these results were used to calculate the Haller and asymmetry indices. The protocol was tested for intradigitizer and interradiologist reliability. Using the Haller and asymmetry indices, we also assessed agreement between radiologists classifying patients as abnormal. RESULTS: Agreement was uniformly high for all comparisons (all Lin's concordance coefficients >0.99 and all Cohen's kappa's >0.85, all agreement on classification of patients >95%) indicating almost perfect agreement. Disagreement on classification of patients using the Haller and asymmetry index was at the cut points for abnormality. CONCLUSION: The protocol was found to be a highly reliable method for deriving the cross-sectional area of the chest and the Haller and asymmetry indices and for classifying patients for surgical eligibility. Borderline cases should be examined carefully to determine the appropriateness of surgical intervention. Cross-sectional area can be measured reliably using this protocol and thus may be useful in quantifying the success of surgical intervention.

Distinctive distribution of pathogens associated with peritonitis in neonates with focal intestinal perforation compared with necrotizing enterocolitis.

OBJECTIVE: Candida and coagulase-negative staphylococci are emerging pathogens associated with focal intestinal perforation (FIP) and necrotizing enterocolitis (NEC) in neonates. The objective of this study was to determine whether there are significant differences in the predominant pathogens in culture-positive cases of peritonitis associated with FIP compared with NEC in neonates. METHODS: A retrospective cross-sectional study was conducted of neonates with peritoneal culture-positive peritonitis associated with FIP or NEC over a 12-year study period (1989-2000). Cases with peritonitis were identified from a microbiology database. NEC was defined by radiologic evidence of pneumatosis intestinalis or portal venous gas or by pathology reports or surgical operative notes describing large areas of transmural bowel necrosis. FIP was defined as a <1-cm intestinal perforation surrounded by otherwise normal tissue in the absence of NEC. RESULTS: Thirty-six cases of FIP were compared with 80 cases of NEC. Birth weight and gestational age were significantly lower in infants with FIP compared with NEC. Age at intestinal perforation and case fatality rates were similar between FIP and NEC. There were striking differences in the distribution of predominant pathogens associated with peritonitis in NEC and FIP cases. Enterobacteriaceae were present in 60 (75%) of 80 NEC cases compared with 9 (25%) of 36 FIP cases. In contrast, Candida species were found in 16 (44%) of 36 FIP cases compared with 12 (15%) of 80 NEC cases, and coagulase-negative staphylococci were present in 18 (50%) of 36 FIP cases versus 11 (14%) of 80 NEC cases. There were no significant differences between FIP and NEC cases for the presence of Enterococcus species (28% vs 23%) or anaerobes (3% vs 6%). Stratified analysis for birth weight <1200 g found similar significant differences in the predominant pathogens for FIP (n = 29) and NEC (n = 38). Results from peritoneal fluid cultures resulted in changes in antimicrobial therapy in 46 (40%) of 116 cases. CONCLUSIONS: Candida species and coagulase-negative staphylococci were the predominant pathogens in FIP peritonitis in contrast to Enterobacteriaceae in NEC peritonitis. A peritoneal fluid culture should be obtained in all neonates with intestinal perforation, regardless of cause, because it may help to direct the choice of the most effective antimicrobial.

Impact of pectus excavatum on pulmonary function before and after repair with the Nuss procedure.

BACKGROUND/PURPOSE: Patient reports of preoperative exercise intolerance and improvement after surgical repair of pectus excavatum (Pex) have been documented but not substantiated in laboratory studies. This may be because no study has been large enough to determine if pulmonary function tests (PFTs) in the Pex population are significantly different from the normal population, and none has assessed improvement in pulmonary function after Nuss bar removal. METHODS: The authors studied PFT results in 408 Pex patients before repair and in a subset of 45 patients after Nuss procedure and bar removal. Significance of differences in percent predicted (using Knudson's equations) was tested using t tests (parametric) or sign tests (nonparametric). Normal was defined as 100% of predicted for forced vital capacity (FVC), forced expired volume in 1 second (FEV1), and forced expiratory flow (FEF25%-75%). RESULTS: Preoperatively, FVC and FEV1 medians were lower than the normal by 13%, whereas the FEF 25-75 median was lower than normal by 20% (all P < .01). The postoperative group had statistically significant improvement after surgery for all parameters. Patients older than 11 years at the time of surgery had lower preoperative values and larger mean post-bar removal improvement than the younger patients. An older patient with a preoperative FEF25-75 score of 80% of normal would be predicted by these data to have a postoperative FEF25-75 of 97%, indicating almost complete normalization for this function. CONCLUSIONS: These results demonstrate that preoperatively Pex patients as a group have decreased lung function relative to normal patients. After Nuss procedure and bar removal, we show a small but significant improvement in pulmonary function. These results are consistent with patient reports of clinical improvement and indicate the need for more in-depth tests of cardiopulmonary function under exercise conditions to elucidate the mechanism.

The minimally invasive Nuss technique for recurrent or failed pectus excavatum repair in 50 patients.

PURPOSE: The aim of this study was to demonstrate the efficacy of the minimally invasive technique for recurrent pectus excavatum. METHODS: Fifty patients with recurrent pectus excavatum underwent a secondary repair using the minimally invasive technique. Data were reviewed for preoperative symptomatology, surgical data, and postoperative results. RESULTS: Prior repairs included 27 open Ravitch procedures, 23 minimally invasive (Nuss) procedures, and 2 Leonard procedures. The prior Leonard patients were also prior Ravitches and are therefore counted only once in the analyses. The median age was 16.0 years (range, 3-25 years). The median computed tomography index was 5.3 (range, 2.9-20). Presenting symptoms included shortness of breath (80%), chest pain (70%), asthma or asthma symptoms (26%), and frequent upper respiratory tract infections (14%). Both computed tomography scan and physical exam confirmed cardiac compression and cardiac displacement. Cardiology evaluations confirmed cardiac compression (62%), cardiac displacement (72%), mitral valve prolapse (22%), murmurs (24%), and other cardiac abnormalities (30%). Preoperative pulmonary function tests demonstrated values below 80% normal in more than 50% of patients. Pectus repair was done using a single pectus bar (66%), 2 bars (32%), or 3 bars (2%). Stabilizers were used in 88% of the patients. Median length of surgical time did not significantly differ from that of primary surgeries. Complications were slightly higher than those in primary repairs and included pneumothorax requiring chest tube (14%), hemothorax (8%), pleural effusion requiring drainage (8%), pericarditis (4%), pneumonia (4%), and wound infection (2%). There were no deaths or cardiac perforations. Initial postoperative results were excellent in 70%, good in 28%, and fair in 2%. Late complications of bar shift requiring revision occurred in 8%. Seventeen patients have had bar removals with 9 patients being more than 1 year postremoval. For the 17 patients who are postremoval, excellent results have been maintained in 8 (47%), good in 7 (41%), fair in 1 (6%), and failed in 1 (6%). There have been no recurrences postremoval. CONCLUSIONS: Although failed or recurrent pectus excavatum repairs are technically more challenging, reoperative correction by the Nuss procedure has met with excellent success.

A pilot study of the impact of surgical repair on disease-specific quality of life among patients with pectus excavatum.

BACKGROUND: This study was conducted to determine the ability of 2 questionnaires (ie, child and parent versions) to measure physical and psychosocial quality-of-life changes after surgical repair of pectus excavatum. METHODS: The authors administered these questionnaires by telephone interviews with 22 parents and 19 children (ages 8 to 18) before surgery and 6 to 12 months after repair by the Nuss procedure. RESULTS: The instruments had high test-retest reliability (Rho > 0.6 for all retained questions). Children reported significant improvements in exercise intolerance, shortness of breath, and tiredness. Of 9 questions asking the children how they feel or act about their bodies, all but one question showed significant improvement after surgery. Parents also reported significant improvements in their child's exercise tolerance, chest pain, shortness of breath, and tiredness and decreases in the frequency of the child being frustrated, sad, self-conscious, and isolated. CONCLUSIONS: These questionnaires appear to be more than adequate to measure disease-specific quality-of-life changes after surgery. These data confirm for the first time that surgical repair of pectus excavatum has a positive impact on both the physical and psychosocial well-being of the child.

Experience and modification update for the minimally invasive Nuss technique for pectus excavatum repair in 303 patients.

PURPOSE: The aim of this study is to review the new technical modifications and results of 303 patients who have had pectus excavatum repair utilizing the minimally invasive technique. METHODS: A retrospective chart review was conducted of 303 patients undergoing minimally invasive pectus repair from 1987 through August 2000. Since 1997, a standardized treatment pathway was implemented, and 261 of the 303 patients have been treated on this pathway. Preoperative evaluation included computed tomography (CT) scan, pulmonary function tests (PFT), and cardiac evaluations with electrocardiogram (EKG) and echocardiogram. Indications for operation included at least 2 of the following: progression of the deformity, exercise intolerance or restrictive disease on PFT, Haller CT index greater than 3.2, mitral valve prolapse (MVP), or cardiac compression. Technical and design modifications since 1998 have included routine thoracoscopy, the use of an introducer/dissector for creating the substernal tunnel and elevating the sternum, and routine use of a wired lateral stabilizer to prevent bar displacement. The bar is removed as an outpatient procedure in 2 to 4 years. RESULTS: In 303 patients undergoing minimally invasive pectus repairs, single bars were used in 87% and double in 13%. Lateral stabilizers were applied in 70% of patients and were wired for further stability in 65%. Bar shifts before the use of stabilizers were 15%, which decreased to 6% after stabilizers were placed and 5% with a wired stabilizer. Excellent results were noted in 85% with failure in only 1 patient. Complications included pneumothorax with spontaneous resolution in half of the patients and pericarditis in 7. CONCLUSIONS: The minimally invasive technique has evolved into an effective method of pectus excavatum repair. Modifications of the technique have reduced complications. Long-term results continue to be excellent.

Central venous catheter removal versus in situ treatment in neonates with coagulase-negative staphylococcal bacteremia.

OBJECTIVE: To determine how often neonates with coagulase-negative staphylococcal (CONS) bacteremia can be treated successfully without removing the central venous catheter (CVC). METHODS: A cohort study of CONS bacteremia and CVCs was conducted in infants in a neonatal intensive care unit in a 5-year period (1994 through 1998). CONS bacteremia was defined as at least two positive blood cultures within 3 days of each other. RESULTS: Fifty-six infants had early removal CVC (ER-CVC) within 3 days, and 63 infants had late removal CVC (LR-CVC) >3 days after the first positive blood culture. All cases of CONS bacteremia were treated with vancomycin. There was no significant difference between infants in the ER-CVC and LR-CVC groups in terms of recurrence of bacteremia or case fatalities. CONS bacteremia of >3 days duration was more frequent in LR-CVC patients than ER-CVC patients: 43% vs. 13% (relative risk, 3.4; 95% confidence interval, 1.6 to 7.2). CONS bacteremia was successfully treated without CVC removal in 46% of LR-CVC cases. Seventy-nine percent of LR-CVC cases with CONS bacteremia lasting 1 or 2 days were treated successfully without CVC removal. The success rate decreased to 44% with a 3- to 4-day duration of bacteremia. None of 19 infants with CONS bacteremia lasting >4 days was treated successfully until CVCs were removed. CONCLUSIONS: Prolonged CONS bacteremia was avoided by early removal of CVCs. Retention of CVCs was successful in 46% of neonates with CONS bacteremia in whom it was attempted, but it was never successful if bacteremia lasted >4 days.
