National Practice Patterns for Prenatal Monitoring in Gastroschisis: Gastroschisis Outcomes of Delivery (GOOD) Provider Survey.

BACKGROUND: Gastroschisis is an abdominal wall defect with increasing incidence. Given the lack of surveillance guidelines among maternal-fetal medicine (MFM) specialists, this study describes current practices in gastroschisis management. MATERIALS AND METHODS: An online survey was administered to MFM specialists from institutions affiliated with the North American Fetal Therapy Network (NAFTNet). Questions focused on surveillance timing, testing, findings that changed clinical management, and delivery plan. RESULTS: Responses were obtained from 29/29 (100%) NAFTNet centers, comprising 143/371 (39%) providers. The majority had a regimen for antenatal surveillance in patients with stable gastroschisis (94%; 134/141). Antenatal testing began at 32 weeks for 68% (89/131) of MFM specialists. The nonstress test (55%; 72/129), biophysical profile (50%; 63/126), and amniotic fluid index (64%; 84/131) were used weekly. Estimated fetal weight (EFW) was performed monthly by 79% (103/131) of providers. At 28 weeks, abnormal EFW (77%; 97/126) and Doppler ultrasound (78%; 99/127) most frequently altered management. In stable gastroschisis, 43% (60/140) of providers delivered at 37 weeks, and 29% (40/ 140) at 39 weeks. DISCUSSION: Gastroschisis management differs among NAFTNet centers, although the majority initiate surveillance at 32 weeks. Timing of delivery still requires consensus. Prospective studies are necessary to further optimize practice guidelines and patient care.

Meconium-stained amniotic fluid as a predictor of poor outcomes in gastroschisis.

OBJECTIVE: The aim of this study was to determine if meconium-stained amniotic fluid (MSAF) was associated with neonatal outcomes in gastroschisis. STUDY DESIGN: A retrospective chart review of gastroschisis patients from 2000 to 2014 at a single, tertiary institution was performed. Statistical analysis was performed with Fisher exact test, Welch's t-test, logistic regression and/or linear regression with significance at p < 0.05. RESULTS: Sixty-four of 135 (47.4%) gastroschisis patients had MSAF. On univariate analysis, patients with MSAF were more likely to require staged closure (30 (46.9%) vs. 18(25.4%), p = 0.012), had more ventilator days (8.9 ±â€¯11.1 vs. 5.3 ±â€¯6.3, p = 0.021) and longer times to commence enteral feeds (24.9 ±â€¯21.7 vs. 18.5 ±â€¯14.5, p = 0.045). However, multi-variate regression analysis controlling for the type of closure, showed that delayed closure, but not MSAF, was associated with worse outcomes. CONCLUSIONS: In gastroschisis patients, MSAF is associated with delayed closure but is not associated with outcomes independent of closure type. This association may be because of the matting of the bowel or increased intestinal damage. The MSAF status will aid in setting expectations for parents during their initial NICU stay and further investigation is warranted. TYPE OF STUDY: Clinical Research Paper Level of evidence: III.

The significance of organ prolapse in gastroschisis.

PURPOSE: The aim of this study was to evaluate the incidence and importance of organ prolapse (stomach, bladder, reproductive organs) in gastroschisis. METHODS: This is a retrospective review of gastroschisis patients from 2000 to 2014 at a single tertiary institution. Statistical analysis was performed using a chi-square test, Student's t test, log-rank test, or Cox regression analysis models. All tests were conducted as two-tailed tests, and p-values <0.05 were considered statistically significant. RESULTS: One hundred seventy-one gastroschisis patients were identified. Sixty-nine (40.6%) had at least one prolapsed organ besides bowel. The most commonly prolapsed organs were stomach (n=45, 26.3%), reproductive organs (n=34, 19.9%), and bladder (n=15, 8.8%). Patients with prolapsed organs were more likely to have simple gastroschisis with significant decreases in the rate of atresia and necrosis/perforation. They progressed to earlier enteral feeds, discontinuation of parenteral nutrition, and discharge. Likewise, these patients were less likely to have complications such as central line infections, sepsis, and short gut syndrome. CONCLUSIONS: Gastroschisis is typically described as isolated bowel herniation, but a large portion have prolapse of other organs. Prolapsed organs are associated with simple gastroschisis, and improved outcomes most likely due to a larger fascial defect. This may be useful for prenatal and postnatal counseling of families. TYPE OF STUDY: Case Control/Retrospective Comparative Study. LEVEL OF EVIDENCE: Level III.

Outcomes of gastroschisis early delivery: A systematic review and meta-analysis.

BACKGROUND/PURPOSE: Elective preterm delivery (EPD) of a fetus with gastroschisis may prevent demise and ameliorate intestinal injury. While the literature on optimal timing of delivery varies, we hypothesize that a potential benefit may be found with EPD. METHODS: A meta-analysis of publications describing timing of delivery in gastroschisis from 1/1990 to 8/2016 was performed, including studies where either elective preterm delivery (group 1, G1) or preterm gestational age (GA) (group 2, G2) were evaluated against respective comparators. The following outcomes were analyzed: total parenteral nutrition (TPN), first enteral feeding (FF), length of stay, ventilator days, fetal demise, complex gastroschisis, sepsis, and death. RESULTS: Eighteen studies describing 1430 gastroschisis patients were identified. G1 studies found less sepsis (p<0.01), fewer days to FF (p=0.03), and 11days less of TPN (p=0.07) in the preterm cohort. Comparatively, G2 studies showed less days to FF in term GA (p=0.02).Whereas G1 BWs were similar, G2 preterm had a significantly lower BW compared to controls (p=0.001). CONCLUSIONS: Elective preterm delivery appears favorable with respect to feeding and sepsis. However, benefits are lost when age is used as a surrogate of EPD. A randomized, prospective, multi-institutional trial is necessary to delineate whether EPD is advantageous to neonates with gastroschisis. TYPE OF STUDY: Treatment study. LEVEL OF EVIDENCE: Level III.

Infectious outcomes of gastroschisis patients with intraoperative hypothermia.

BACKGROUND: Perioperative hypothermia decreases nutrient and oxygen delivery to tissues and, in adult studies, increases the risk of infectious complications (ICs). Gastroschisis (GS) places newborns at risk for hypothermia by nature of exposed viscera and excessive heat loss. Although hypothermia is a known cause of mortality in GS, the rate of ICs in this at-risk cohort has not yet been delineated. MATERIALS AND METHODS: A retrospective cohort study was performed at our single tertiary-referral hospital, evaluating patient and operative characteristics of all GS infants who underwent operative closure. Intraoperative temperatures were recorded, defining hypothermia as mild (35.5°C-35.9°C), moderate (35.0°C-35.4°C), or severe (<35°C). Temperature nadirs, procedural and anesthesia duration were observed. The primary outcome was 30-d surgical site infections. Secondary measures included other ICs. RESULTS: Among 43 GS neonates, 21 (48.8%) had intraoperative hypothermia, classified as mild in 2 (4.7%), moderate in 8 (18.6%), and severe in 11 (25.6%). Nineteen ICs occurred in 35.9% of patients, including 10 (23.3%) surgical site infections. There was no association between hypothermia and ICs. Patient and operative characteristics were similar between normothermic and hypothermic groups, except that normothermic infants were more likely to have silos placed with delayed closure than hypothermic patients (63.6% versus 23.8%, P = 0.01). CONCLUSIONS: Infants with GS are at high risk for hypothermia and ICs, though newborns with silos were less subject to temperature lability. A multiinstitutional study with greater power is needed to further investigate the relationship between perioperative hypothermia and surgical ICs.

Effects of anticipated neonatal surgical intervention on maternal milk cytokine production.

BACKGROUND: Maternal stress on neonatal outcomes of infants admitted to the NICU is incompletely understood. We previously demonstrated breast milk derived cytokines remain biologically active in the neonatal intestine. We hypothesized that the need for neonatal surgical intervention would be stimulus leading to maternal cytokine production thus affecting neonatal outcome. METHODS: Discarded expressed breast milk (EBM) in the first 3weeks following delivery was analyzed for IL-23 and IL-10 by ELISA. Variables analyzed included: the need for a pediatric surgical procedure, the need for cardiac surgical procedure, no surgical interventions, and survival. All values are expressed as mean±SEM. Statistical analysis utilized Kruskal and Mann-Whitney test. RESULTS: EBM from mothers whose infants required any surgical procedure (n=19) revealed significant elevation in IL-10 but not IL-23 compared to nonsurgical EBM (n=18). Subdivided by procedure type, there was no difference between those undergoing a cardiac (n=9) versus pediatric surgical (n=10) procedure in both IL-10 and IL-23. Mothers whose infants requiring surgical intervention or whose infants did not survive in the first 3weeks of life had elevation of IL-10. CONCLUSION: Results suggest maternal stress impacts the cytokine profile of breast milk. LEVEL OF EVIDENCE: Level III.

Can omphalocele ratio predict postnatal outcomes?

BACKGROUND: The clinical course of patients with omphalocele is challenging to predict. There is no standard method to characterize omphalocele size. Previous studies suggest that the ratio of abdominal circumference to omphalocele defect in-utero is indicative of postnatal outcomes. We hypothesize that omphalocele ratio correlates with outcomes of primary closure versus staged closure. METHODS: A retrospective chart review of all neonates diagnosed with omphalocele from 2002 to 2013 with prenatal ultrasounds available (n=30) was conducted. Omphalocele ratio was defined as omphalocele diameter/abdominal circumference (OD/AC). Data collected included primary versus staged closure, time to full feeds, duration of mechanical ventilation, and length of stay (LOS). Long-term outcomes and quality of life were also reported. RESULTS: ROC curve analysis generated optimal OD/AC ratio of 0.26. Twenty of 30 patients had a ratio less than this cutoff. Sixty percent (12/20) in the low-ratio group achieved primary closure versus zero (0/10) in the high-ratio group (p=0.001). Time on mechanical ventilation was 15.8 days (low-ratio) versus 79 days (high-ratio) (p=0.05). LOS was 33.8 days (low-ratio) versus 85.6 days (high-ratio) (p=0.119). PedsQL™ mean score was 85.5 ± 11.0 (n=20) at long-term follow-up. Readmission rates yielded no difference. CONCLUSIONS: The omphalocele ratio is a promising predictor of postnatal outcomes.

Safety of Enteral Feedings in Critically Ill Children Receiving Vasoactive Agents.

BACKGROUND: The objective of this retrospective study was to evaluate the safety of enteral feeding in children receiving vasoactive agents (VAs). METHODS: Patients aged 1 month to 18 years with a pediatric intensive care unit stay for ≥96 hours during 2007 and 2008 who received any VA (epinephrine, norepinephrine, vasopressin, milrinone, dopamine, and dobutamine) were included and categorized into fed and nonfed groups. Their demographics, clinical characteristics, type and dose of VA, and presence of gastrointestinal (GI) outcomes were obtained. GI outcomes were compared between the groups by the χ(2) test, Mann-Whitney test, and logistic regression. RESULTS: In total, 339 patients were included. Of these, 55% were in the fed group and 45% in the nonfed group. Patients in the fed group were younger (median age, 1.05 vs 2.75 years, respectively; P < .001) and tended to have a lower Pediatric Index of Mortality 2 (PIM2) risk of mortality (ROM) than those in the nonfed group (median, 3.33% vs 3.52%, respectively; P = .106). Mortality was lower in the fed group than the nonfed group (6.9% vs 15.9%, respectively; odds ratio [OR], 0.39; 0.18-0.84; P < .01, 95% CI), while GI outcomes did not differ between the groups. The vasoactive-inotropic score (VIS) did not differ between the groups except on day 1 (P = .017). The ROM did not differ between the groups after adjusting for age, PIM2 ROM, and VIS on day 1 (OR, 0.58; 0.26-1.28; P = .18, 95% CI). CONCLUSIONS: Enteral feeding in patients receiving VAs is associated with no difference in GI outcomes and a tendency towards lower mortality. Prospective studies are required to confirm the safety of enteral feedings in patients receiving VAs.

Gastrojejunostomy Tube Bowel Perforations in Low-Weight Infants.

This is a case series in which 3 infants with gastrojejunostomy tube (GJT) insertion developed delayed perforation secondary to pressure necrosis. A review of all patients who underwent a GJT placement in 2013 was performed. Three of these patients developed surgically confirmed perforation secondary to pressure necrosis during this time period; no patients developed perforation at the time of GJT insertion. The indications for GJT insertion for all 3 patients were severe gastroesophageal reflux disease; 2 patients also had recurrent aspiration. The patients were between 9 weeks and 10 months of age at the time of GJT insertion. The site of perforation for all 3 cases occurred just distal to the ligament of Treitz between 48 and 72 hours following insertion. Given our 3 cases of perforation in patients weighing <10 kg, there may be a higher risk of perforation in low-weight patients.

Genetic Evaluation of E. coli Strains Isolated from Asymptomatic Children with Neurogenic Bladders.

This study was conducted to describe the genetic profiles of E. coli that colonize asymptomatic pediatric neurogenic bladders. E. coli was isolated from 25 of 80 urine samples. Patients were excluded if they presented with symptomatic urinary tract infection or received treatment with antibiotics in the preceding three months. Multiplex PCR was performed to determine E. coli phylotype (A, B1, B2, and D) and the presence of seven pathogenicity islands (PAIs) and 10 virulence factors (VFs). E. coli strains were predominantly of the B1 and B2 phylotype, with few strains in the A or D phylotype. The PAIs IV536, ICFT073, and IICFT073 had the highest prevalence: 76%, 64%, and 48%, respectively. The PAIs II536, IJ96, and IIJ96 were less prevalent: 28%, 20%, and 24%, respectively. The most prevalent VF was vat (40%), while the least prevalent VFs were sfa (8%) and iha (12%). None of the strains carried the VF fyuA, which is very common in uropathogenic E. coli (UPEC). The genetic profiles of E. coli in this cohort seem to be more similar to UPEC than to commensal E. coli. However, they appear to have reduced virulence potential that allows them to colonize asymptomatically.

Observation versus prophylactic Ladd procedure for asymptomatic intestinal rotational abnormalities in heterotaxy syndrome: A systematic review.

BACKGROUND: The management of intestinal rotational abnormalities (IRA) in heterotaxy syndrome (HS) remains inconsistent. Because of the high incidence of malrotation in HS, screening of asymptomatic patients is standard of care in some institutions. The Ladd procedure is the treatment for malrotation, and has been reported to have high complication rates in HS patients. METHODS: We performed a systematic review of publications describing IRA in pediatric HS patients from January 1993 to present. The incidence of volvulus on surgical exploration was determined. Perioperative and long-term outcomes were analyzed to determine complication and mortality rates. RESULTS: Eleven retrospective studies describing 649 HS patients were identified. Of all patients with HS, 27% (176/649) underwent Ladd procedure. Only 1.2% (8/649) of HS patients included had volvulus. Postoperative complications occurred in 25 patients (14%), including a 10% incidence of small bowel obstruction. Perioperative and overall mortality rates after Ladd procedure were 3% and 21%, respectively. Six studies described mesenteric width, reporting 43% to have narrow mesentery. CONCLUSION: The Ladd procedure is not without significant morbidity and mortality in heterotaxy patients. Further prospective studies should investigate predictors of mesenteric width to spare the unnecessary morbidity of surgery in patients who are at low risk for volvulus.

Safe and effective management of esophageal coins in children with bougienage.

BACKGROUND: Coins are the foreign body most commonly ingested in infants and children. Coins retained in the esophagus require intervention to prevent complications. Management of retained esophageal coins remains variable both between and within institutions. We hypothesize that the incorporation of bougienage in the management of pediatric esophageal coins is safe and more cost-effective compared with traditional management strategies that use endoscopy. METHODS: We conducted a retrospective review of infants and children diagnosed with an esophageal foreign body managed at Children's Hospital of Wisconsin between January 2003 and June 2012. Pediatric otolaryngologists (ear-nose-throat, ie, ENTs) or pediatric surgeons manage all children with esophageal foreign bodies in a prospective call schedule that alternates weekly. RESULTS: During an 8.5-year period, 1,642 children were diagnosed with esophageal foreign bodies and 518 had a retained coin. For esophageal coins, ENT managed 218 cases and pediatric surgery managed 300. ENTs preferentially used endoscopy for coin removal, whereas pediatric surgeons used either endoscopy or esophageal bougienage for selected children meeting specific criteria. Bougienage was successful at advancing the coin into the stomach in 94% of patients, and endoscopy was successful at removing the coin from the esophagus in 100% of patients. The mean duration of stay was 0.6 days for endoscopy by ENT, 0.6 days for endoscopy by pediatric surgery, and 0.1 days for bougienage (P < .05). The median hospital charge was $4,593 for endoscopy by ENT, $5,379 for endoscopy by pediatric surgery, and $579 for bougienage (P < .05). There were 3 complications each in the endoscopy group for ENT and pediatric surgery. There were no complications in children undergoing bougienage. CONCLUSION: This is the first case series evaluating the management of children with esophageal coins using a prospective assignment to endoscopy versus endoscopy or bougienage. Our data support bougienage as a safe and cost-effective treatment for managing retained esophageal coins in selected children.

Does the American College of Surgeons NSQIP-Pediatric Accurately Represent Overall Patient Outcomes?

BACKGROUND: The National Surgical Quality Improvement Program-Pediatrics (NSQIP-P) collects data for institutional quality benchmarking of surgery performed on children using a sampling algorithm. The Pediatric and Infant Case Log and Outcomes (PICaLO) is a database of all general and thoracic pediatric surgery (GTPS) procedures performed at our institution with the attendant complications. This study compared postsurgical occurrences in a NSQIP-P sample with all postoperative occurrences at a single institution to test the hypothesis that a sample of higher risk procedures represents the actual event rate for all higher risk procedures. STUDY DESIGN: The definitions of postoperative occurrences used in PICaLO are derived from NSQIP-P but tracked past 30 days postoperatively and include additional occurrences (ie, anastomotic leak). The number and types of occurrences and number of deaths from PICaLO and NSQIP-P databases were compared for procedures specific to pediatric GTPS procedures during 2012 to 2013. A chi-square test evaluated the proportion of occurrences and deaths in PICaLO to NSQIP-P. RESULTS: The NSQIP-P sampled 37.7% of eligible GTS procedures recorded in PICaLO during the study period. The proportion of cases with 1 or more occurrences was significantly higher in the NSQIP-P dataset when compared with all cases in PICaLO (p < 0.0001). When NSQIP-P and PICaLO were compared based on specific CPT codes, NSQIP-P still had a higher event rate (p = 0.004). CONCLUSIONS: In focused comparisons, the data demonstrate that the NSQIP-P sampling algorithm successfully identifies CPT codes with higher postoperative event rates than the overall cohort of pediatric GTPS patients, but may not be reflective of the total experience for procedures with those CPT codes.

Operationalizing quality improvement in a pediatric surgical practice.

BACKGROUND/PURPOSE: Quality improvement (QI) is critical to enhancing patient care. It is necessary to prioritize which QI initiatives are relevant to one's institution and practice, as implementation is resource-intensive. We have developed and implemented a streamlined process to identify QI opportunities in our practice. METHODS: We designed a web-based Pediatric and Infant Case Log and Outcomes (PICaLO) instrument using Research Electronic Data Capture (REDCap™) to record all surgical procedures for our practice. At the time of operation, a surgeon completes a case report form. An administrative assistant enters the data in PICaLO within 5-7days. Outcomes such as complications, deaths, and "occurrences" (readmissions, reoperations, transfers to ICU, ER visit, additional clinic visits) are recorded at the time of encounter, during M & M Conferences, and during follow-up clinic visits. Variables were chosen and defined based on national standards from the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP), and Patient Based Learning Log. Occurrences are queried for potential QI initiatives. RESULTS: In 2012, 3597 patients were entered, totaling 5177 procedures. There were 220 complications, 278 occurrences, and 16 deaths. Specific QI opportunities were identified and put into place. CONCLUSION: Data on procedures and outcomes can be collected effectively in a pediatric surgery practice to delineate pertinent QI initiatives. PICaLO is recognized by the American Board of Surgery as a mechanism to meet Maintenance of Certification 4 criteria.

Early enteral nutrition is associated with lower mortality in critically ill children.

BACKGROUND: The purpose of this study was to examine the association of early enteral nutrition (EEN), defined as the provision of 25% of goal calories enterally over the first 48 hours of admission, with mortality and morbidity in critically ill children. METHODS: We conducted a multicenter retrospective study of patients in 12 pediatric intensive care units (PICUs). We included patients aged 1 month to 18 years who had a PICU length of stay (LOS) of ≥96 hours for the years 2007-2008. We obtained patients' demographics, weight, Pediatric Index of Mortality-2 (PIM2) score, LOS, duration of mechanical ventilation (MV), mortality data, and nutrition intake data in the first 4 days after admission. RESULTS: We identified 5105 patients (53.8% male; median age, 2.4 years). Mortality was 5.3%. EEN was achieved by 27.1% of patients. Children receiving EEN were less likely to die than those who did not (odds ratio, 0.51; 95% confidence interval, 0.34-0.76; P = .001 [adjusted for propensity score, PIM2 score, age, and center]). Comparing those who received EEN to those who did not, adjusted for PIM2 score, age, and center, LOS did not differ (P = .59), and the duration of MV for those receiving EEN tended to be longer than for those who did not, but the difference was not significant (P = .058). CONCLUSIONS: EEN is strongly associated with lower mortality in patients with PICU LOS of ≥96 hours. LOS and duration of MV are slightly longer in patients receiving EEN, but the differences are not statistically significant.

Metabolic evaluation of urolithiasis and obesity in a midwestern pediatric population.

PURPOSE: The incidence of urolithiasis has been proved to be increasing in the adult population, and evidence to date suggests that the same holds true for the pediatric population. While adult urolithiasis is clearly linked to obesity, studies of pediatric patients have been less conclusive. We hypothesized that a population of otherwise healthy children with stones would have an increased body mass index compared to a control population, and that obese pediatric stone formers would have results on metabolic assessment that are distinct from nonobese stone formers. MATERIALS AND METHODS: We retrospectively reviewed the charts of all patients 10 to 17 years old with upper tract urolithiasis without comorbidities treated between 2006 and 2011. Mean body mass index of our population was compared to state data, and 24-hour urine collection results were compared between obese and nonobese patients with stones. RESULTS: The obesity rate in 117 patients with urolithiasis did not differ significantly from the obesity rate derived from the 2007 National Survey of Children's Health (observed/expected ratio 1.11, 95% CI 0.54-1.95). Using t-test and chi-square comparisons, overall 24-hour urine collection data did not show statistically significant differences. CONCLUSIONS: Our results do not confirm obesity as a risk factor for pediatric urolithiasis in otherwise healthy patients. We also found no substantial metabolic differences between healthy nonobese stone formers and obese patients. While the pediatric literature is mixed, our study supports the majority of published series that have failed to establish a link between pediatric urolithiasis and obesity.

Under pressure: preventing pressure ulcers in critically ill infants.

PURPOSE: To determine whether a pressure ulcer prevention bundle was associated with a significant reduction in pressure ulcer development in infants in the pediatric intensive care unit. DESIGN AND METHODS: Quasi-experimental design involving 399 infants 0 to 3 months of age at a large tertiary care medical center. RESULTS: The implementation of the care bundle was associated with a significant drop in pressure ulcer incidence from 18.8 to 6.8%. PRACTICE IMPLICATIONS: Pressure ulcers can be prevented in the most vulnerable patients with the consistent implementation of evidence-based interventions and system supports to assist nurses with the change in practice.

Registered dietitians making a difference: early medical record documentation of estimated energy requirement in critically ill children is associated with higher daily energy intake and with use of the enteral route.

BACKGROUND: Establishing a caloric requirement or energy target is a recommended part of any nutrition care plan. OBJECTIVE: Our objective was to describe early documentation of a caloric requirement in critically ill children, and to determine if this would have any effect on daily energy intake and route of nutrition. DESIGN: We used a descriptive chart review of a subgroup of patients included as part of a larger, retrospective multicenter study. Variables of interest included nutritional intake information, as well as presence/absence and amount of a documented caloric requirement within 48 hours of admission. PARTICIPANTS: Five of the original 12 study centers collected the required supplementary data. Enrolled patients were those who were admitted to our pediatric intensive care unit (PICU) from January 1, 2007, through December 31, 2008; were between ages 30 days and 18 years; and had a length of stay in the PICU ≥ 96 hours. STATISTICAL ANALYSIS: Energy intake among patients with and without a documented caloric requirement was analyzed using Mann-Whitney U tests. The difference of receiving enteral nutrition among patients with and without a caloric requirement was analyzed using a χ(2) test. RESULTS: We studied 1,349 patients, of whom 644 (47.7%) had a caloric requirement documented (95.6% of caloric requirements were entered by a registered dietitian) in the medical record; these patients had higher total daily energy intake and were more likely to be fed enterally during the first 4 days of PICU admission than those without a documented caloric requirement (P<0.001 for all comparisons). CONCLUSIONS: Less than half of critically ill children studied had a caloric requirement documented in the medical record; when a caloric requirement was documented in the medical record of a critically ill child, a registered dietitian had likely made the note. Having a caloric requirement documented in the medical record is associated with a higher energy intake and the use of the enteral route.

Effectiveness of clinical guidelines for deep vein thrombosis prophylaxis in reducing the incidence of venous thromboembolism in critically ill children after trauma.

BACKGROUND: Historically, 6% of critically ill children developed clinically apparent venous thromboembolism (VTE) after trauma at our Level I pediatric trauma center. We hypothesized that implementation of clinical guidelines for thrombosis prophylaxis incorporating both VTE risk and bleeding risk would reduce VTE incidence without increased bleeding. METHODS: VTE, both clinically apparent and those only detected by guideline-directed screening, were prospectively identified for all children admitted to the intensive care unit after trauma during three time periods: preimplementation of guidelines for VTE thromboprophylaxis (PRE; April 1, 2006-June 30, 2007), the intervening period (ROLL OUT; July 1, 2007-November 4, 2008), and postguideline implementation (POST; November 5, 2008-June 1, 2010). For patients classified as high risk for VTE, anticoagulation was recommended. For those patients at high risk of VTE with high risk of bleeding, anticoagulation was deferred and screening ultrasound performed. RESULTS: Fourteen of 546 subjects developed VTE. There was a decrease in total VTE (p = 0.041) and clinical VTE (p = 0.001) after guideline implementation. The nine VTE PRE (5.2%) were clinically symptomatic, while the three VTE POST (1.8%) were detected by guideline-directed screening ultrasound. Implementation of guidelines did not increase overall thromboprophylaxis, with decreased anticoagulation in patients at low risk of VTE. No bleeding complications occurred. No patients classified by the guidelines as low risk for VTE developed VTE. CONCLUSION: The incidence of clinical VTE and total VTE decreased after implementation of clinical guidelines for thromboprophylaxis in critically ill children after trauma. This decrease in VTE was not associated with increased prophylactic anticoagulation nor increased bleeding. The guidelines were predictive in identifying patients at low risk for VTE. LEVEL OF EVIDENCE: II, therapeutic study.

Incidence and risk factors for venous thromboembolism in critically ill children with cardiac disease.

Cardiac disease is a risk factor for venous thromboembolism (VTE) in children. In this study, we investigated the incidence and risk factors of VTE in critically ill children with cardiac disease, who were prospectively followed-up for VTE after admission to a tertiary care pediatric intensive care unit (PICU). Risk factors were compared between VTE cases and (1) patients in the cohort who did not develop VTE and (2) the next three cardiac patients sequentially admitted to the PICU (case control). Forty-one cases of VTE were identified from 1070 admissions (3.8%). Thirty-seven percent of VTE cases were central venous catheter (CVC)-associated, and 56% of cases were intracardiac. Sixty-six percent of patients were receiving anticoagulation at the time of VTE diagnosis. Increased VTE incidence was associated with unscheduled PICU admission, age <6 months, extracorporeal membrane oxygenation, increased number of CVCs, increased number of CVC days, higher risk of mortality score, and longer PICU stay. Using logistic regression, VTE was associated with single-ventricle physiology (odds ratio [OR] 11.2, 95% CI 3.0-41.9), widened arterial-to-somatic oxygen saturation gradient (SpO(2)-rSO(2) >30) (OR 4.3, 95% CI 1.1-16), and more CVC days (OR 1.1, 95% CI 1.04-1.13). Risk factors for VTE in critically ill children with cardiac disease include younger age, single-ventricle cardiac lesions, increased illness severity, unscheduled PICU admission, and complicated hospital course.
