ABSTRACT

PURPOSE: Obesity is an independent risk factor in trauma-related morbidity in adults. The purpose of this study was to investigate the effect of obesity in the pediatric trauma population. METHODS: All patients (6-20 years) between January 2004 and July 2007 were retrospectively reviewed and defined as non-obese (body mass index [BMI] <95th percentile for age) or obese (BMI > or =95th percentile for age). Groups were compared for differences in demographics, initial vital signs, mechanisms of injury, length of stay, intensive care unit stay, ventilator days, Injury Severity Score, operative procedures, and clinical outcomes. RESULTS: Of 1314 patients analyzed, there were 1020 (77%) nonobese patients (mean BMI = 18.8 kg/m(2)) and 294 (23%) obese patients (mean BMI = 29.7 kg/m(2)). There was no significant difference in sex, heart rate, length of stay, intensive care unit days, ventilator days, Injury Severity Score, and mortality between the groups. The obese children were significantly younger than the nonobese children (10.9 +/- 3.3 vs 11.5 +/- 3.5 years; P = .008) and had a higher systolic blood pressure during initial evaluation (128 +/- 17 vs 124 +/- 16 mm Hg, P < .001). In addition, the obese group had a higher incidence of extremity fractures (55% vs 40%; P < .001) and orthopedic surgical intervention (42% vs 30%; P < .001) but a lower incidence of closed head injury (12% vs 18%; P = .013) and intraabdominal injuries (6% vs 11%; P = .023). Evaluation of complications showed a higher incidence of decubitus ulcers (P = .043) and deep vein thrombosis (P = .008) in the obese group. CONCLUSION: In pediatric trauma patients, obesity may be a risk factor for sustaining an extremity fracture requiring operative intervention and having a higher risk for certain complications (ie, deep venous thrombosis [DVT] and decubitus ulcers) despite having a lower incidence of intracranial and intraabdominal injuries. Results are similar to reports examining the effect(s) of obesity on the adult population.

ABSTRACT

PURPOSE: The Canadian C-spine (cervical spine) Rule (CCR) and the National Emergency X-Radiography Utilization Low-Risk Criteria (NLC) are criteria designed to guide C-spine radiography in trauma patients. It is unclear how these 2 rules compare with young children. METHODS: This study retrospectively examined case-matched trauma patients 10 years or younger. Two cohorts were identified-cohort A where C-spine imaging was performed and cohort B where no imaging was conducted. The CCR and NLC criteria were then applied retrospectively to each cohort. RESULTS: Cohort A contained 125 cases and cohort B with 250 cases. Seven patients (3%) had significant C-spine injuries. In cohort A, NLC criteria could be applied in 108 (86.4%) of 125 and CCR in 109 (87.2%) of 125. National Emergency X-Radiography Utilization Low-Risk Criteria suggested that 70 (58.3%) cases required C-spine imaging compared to 93 (76.2%) by CCR. National Emergency X-Radiography Utilization Low-Risk Criteria missed 3 C-spine injuries, and CCR missed one. In cohort B, NLC criteria could be applied in 132 (88%) of 150 and CCR in 131 (87.3%) of 150. The NLC criteria identified 8 cases and CCR identified 13 cases that would need C-spine radiographs. Fisher's 2-sided Exact test demonstrated that CCR and NLC predictions were significantly different (P = .002) in both cohorts. The sensitivity of CCR was 86% and specificity was 94%, and the NLC had a sensitivity of 43% and a specificity of 96%. CONCLUSIONS: Although CCR and NLC criteria may reduce the need for C-spine imaging in children 10 years and younger; they are not sensitive or specific enough to be used as currently designed.

ABSTRACT

PURPOSE: Computed tomographic (CT) scanning has mostly replaced x-rays as an imaging modality, but concerns exist because of excess radiation, missed injuries, and whether it is the definitive procedure for intubated patients. The purpose of this study was to characterize missed cervical spine injuries (CSIs). METHODS: All pediatric (<18) trauma patients from 2004 to 2006 were analyzed. Age, sex, Injury Severity Score (ISS), mechanism, time, and missed injuries were reviewed. Flexion/extension views were used in patients with prolonged intubation. Descriptive statistics, chi(2), Student's t test, and bivariate correlation were used. RESULTS: There were 1307 pediatric trauma patients admitted with 318 imaged for potential CSI. Computed tomography was the sole imaging study in 200, x-rays in 64, and both in 54. Time to C-spine clearance was similar for all modalities (P > .05). For CT, 34 (10.7%) were initially positive for CSI with 7 false-positives (FPs) and no false-negative (FN). There were 18 patients with CSI identified by x-ray, with 5 FPs and 5 FNs (missed injuries). The 5 FNs missed by x-ray were all positive by CT scan and required no intervention. None of the flexion/extension views revealed an additional injury. Sex, intubated patients, ISS, age, type, and injury location were not predictive of a missed injury (P > .05).The sensitivity of CT scan was 1.0, specificity was 0.976, and the positive predictive value was 79.4%. The sensitivity of plain x-ray was 61.5%, the specificity was 1.6%, and the positive predictive value was 61.5%. CONCLUSIONS: Our data suggest that CT scans should be the primary modality to image a CSI. Flexion/extension views did not add to the decision making for C-spine clearance after CT evaluation.

ABSTRACT

BACKGROUND: Infants with severe congenital diaphragmatic hernia (CDH) requiring extracorporeal membrane oxygenation (ECMO) have a high morbidity and mortality. We hypothesized that placement of an abdominal wall silo and staged abdominal wall closure may reduce problems associated with decreased abdominal domain in CDH. METHODS: We performed a retrospective review and identified 7 CDH patients requiring ECMO who had a silastic abdominal wall silo between 2003 and 2006. Variables analyzed included survival, ECMO duration, duration of silo, time to discharge, and long-term outcome. RESULTS: Predicted mean survival for the entire cohort using the published CDH Study Group equation was 47% (range, 9%-86%). All 7 patients (100%) survived. Extracorporeal membrane oxygenation duration averaged 15 days (range, 5-19 days). Four of the patients (58%) were repaired with a silo on ECMO, and 3 (42%) had their repair after ECMO. The abdominal wall defect was closed at a mean of 21 days (range, 4-41 days). Hospital stay after silo placement averaged 54 days (range, 20-170 days) with no infections or wound complications. CONCLUSIONS: Abdominal wall silo placement in infants with CDH requiring ECMO appears to be an effective strategy for decreased abdominal domain. Further studies are warranted to determine the efficacy of such a strategy for these high-risk CDH patients.

ABSTRACT

INTRODUCTION: The appendectomy is a common emergent surgical procedure in the pediatric population. The aim of this study was to examine our institution's experience and outcomes in the appendectomy in the pediatric population early in our transition from open surgery to a predominantly laparoscopic approach. METHODS: We retrospectively studied all pediatric patients (age 20 years) that underwent an appendectomy at a tertiary care center over 2 years. The data collected included patient demographics, comorbidities, operative details, outcomes, and complications. RESULTS: Two hundred twenty-three consecutive patients, with a mean age of 9.5 (3.9) years, were included in the study. Forty-four laparoscopic and 179 open appendectomies were performed. Two of the laparoscopic cases were converted to open appendectomies. Significant differences were seen between the two groups, with longer operative times (P < 0.0001) and lower estimated blood loss (P = 0.007) in the laparoscopic group. Operative times improved significantly for the laparoscopic group as the surgeons became more experienced (P = 0.03). The laparoscopic group used intravenous pain medication for a shorter time (0.8 vs. 1.9 days; P = 0.0003) and had a shorter postoperative hospital length of stay (2.2 vs. 3.4 days; P = 0.004). The laparoscopic group had fewer wound infections (2.3% vs. 6.2%; P = 0.3), intra-abdominal abscesses (4.5% vs. 5.6%; P = 0.8), and postoperative ileus (0% vs. 2.2%; P = 0.3), although these differences did not reach statistical significance. CONCLUSION: The laparoscopic appendectomy procedure is a safe alternative to open appendectomy in pediatric patients and results in shorter hospital stays with less postoperative pain.

ABSTRACT

Right colon resections are perceived as less morbid than left colon resections. The purpose of this study was to determine the differences in outcomes between right-and left-side colon resections. We reviewed 420 consecutive open colectomies over 4 years. Patient demographics, surgical indications, intraoperative variables, and outcomes were collected. Two hundred twenty-three right colectomies (RCs) were compared with 197 left colectomies (LCs). RCs were more often required for cancer (111 vs 65, P < .001) and LCs for diverticular disease (10 vs 90, P < .001). LCs were more often performed emergently (36% vs 23%, P = .004) and required longer mean operative times (149 minutes vs 130 minutes, P = .004). Complications and mortality in the two groups were equal statistically. In the emergent colectomy subset, LCs were associated with greater intraoperative blood loss (315 vs 201 mL, P = .02) but fewer complications (11% vs 17%, P = .003).
