Project description:Background:Sugammadex is a novel, rapidly-acting pharmacologic agent to reverse steroidal neuromuscular blocking agents with demonstrated advantages over acetylcholinesterase inhibitors. However, anecdotal reports have noted rare instances of bradycardia and even cardiac arrest. The current study examined heart rate (HR) changes in infants and children with comorbid cardiac, cardiovascular, and congenital heart diseases. Methods:Patients less than 18 years of age, who had a comorbid cardiac, cardiovascular, or congenital heart disease and were to receive sugammadex, were included in this prospective observational study. After sugammadex administration, HR was continuously monitored and recorded every minute for the first 15 min, and then every 5 min for the next 15 min or until the patient was transferred from the operating room. The primary outcome, bradycardia, was defined as HR below the fifth percentile for age. Secondary outcomes included greatest decrease in HR from baseline for each patient and interventions required for bradycardia. Results:The study cohort included 99 patients (58 male and 41 female) with a median age of 3 years. Bradycardia was noted in 20 of 99 patients (20%); however, six of these patients were bradycardic prior to the administration of sugammadex. Older patients, male patients, and patients with higher body weight were the most likely to experience bradycardia. None of the patients required treatment for bradycardia. Conclusions:The incidence of bradycardia following the administration of sugammadex was low, even in patients with congenital heart disease. Bradycardia was not associated with clinically significant hemodynamic changes and no treatment was required.

Project description:ObjectivesThe Pediatric Heart Network sponsored the multicenter Collaborative Learning Study that implemented a clinical practice guideline to facilitate early extubation in infants after repair of isolated coarctation of the aorta and tetralogy of Fallot. We sought to compare the anesthetic practice in the operating room and sedation-analgesia management in the ICU before and after the implementation of the guideline that resulted in early extubation.DesignSecondary analysis of data from a multicenter study from January 2013 to April 2015. Predefined variables of anesthetic, sedative, and analgesia exposure were compared before and after guideline implementation. Propensity score weighted logistic regression analysis was used to determine the independent effect of intraoperative dexmedetomidine administration on early extubation.SettingFive children's hospitals.PatientsA total of 240 study subjects who underwent repair of coarctation of the aorta or tetralogy of Fallot (119 preguideline implementation and 121 postguideline implementation).InterventionsNone.Measurements and main resultsClinical practice guideline implementation was accompanied by a decrease in the median total intraoperative dose of opioids (49.7 vs 24.0 µg/kg of fentanyl equivalents, p < 0.001) and benzodiazepines (1.0 vs 0.4 mg/kg of midazolam equivalents, p < 0.001), but no change in median volatile anesthetic agent exposure (1.3 vs 1.5 minimum alveolar concentration hr, p = 0.25). Intraoperative dexmedetomidine administration was associated with early extubation (odds ratio 2.5, 95% CI, 1.02-5.99, p = 0.04) when adjusted for other covariates. In the ICU, more patients received dexmedetomidine (43% vs 75%), but concomitant benzodiazepine exposure decreased in both the frequency (66% vs 57%, p < 0.001) and cumulative median dose (0.5 vs 0.3 mg/kg of ME, p = 0.003) postguideline implementation.ConclusionsThe implementation of an early extubation clinical practice guideline resulted in a reduction in the dose of opioids and benzodiazepines without a change in volatile anesthetic agent used in the operating room. Intraoperative dexmedetomidine administration was independently associated with early extubation. The total benzodiazepine exposure decreased in the early postoperative period.

Project description:Cardiac arrest (CA), the sudden cessation of effective cardiac pumping function, is still a major clinical problem with a high rate of early and long-term mortality. Post-cardiac arrest syndrome (PCAS) may be related to an early systemic inflammatory response leading to exaggerated and sustained neuroinflammation. Therefore, early intervention with targeted drug delivery to attenuate neuroinflammation may greatly improve therapeutic outcomes. Using a clinically relevant asphyxia CA model, we demonstrate that a single (i.p.) dose of dendrimer-N-acetylcysteine conjugate (D-NAC), can target "activated" microglial cells following CA, leading to an improvement in post-CA survival rate compared to saline (86% vs. 45%). D-NAC treatment also significantly improved gross neurological score within 4 h of treatment (p < 0.05) and continued to show improvement at 48 h (p < 0.05). Specifically, there was a substantial impairment in motor responses after CA, which was subsequently improved with D-NAC treatment (p < 0.05). D-NAC also mitigated hippocampal cell density loss seen post-CA in the CA1 and CA3 subregions (p < 0.001). These results demonstrate that early therapeutic intervention even with a single D-NAC bolus results in a robust sustainable improvement in long-term survival, short-term motor deficits, and neurological recovery. Our current work lays the groundwork for a clinically relevant therapeutic approach to treating post-CA syndrome.

Project description:ObjectivesThe purpose of this study was to evaluate the association between the method of procedural sedation and outcomes for congenital cardiac catheterization procedures.BackgroundThe safety of operator-directed sedation (ODS) in the pediatric/congenital cardiac catheterization laboratory has been questioned. To our knowledge, the relative safety of ODS versus general anesthesia (GA) in these cases has not to date been critically evaluated.MethodsA single-center retrospective cohort study was performed to compare the relative safety, cost, and times of catheterization procedures performed with ODS and those performed with GA from a cardiac anesthesiologist. The risk of adverse outcomes was compared using propensity-score-adjusted models. Using the same propensity score, procedure times and relative charges were also compared.ResultsOver the study period, 4,424 procedures in 2,547 patients were studied. Of these, 27% of cases were performed with ODS. ODS procedures were 70% diagnostic procedures, 17% device closure of patent ductus arteriosus, 5% balloon pulmonary valvuloplasty, and 3% pulmonary artery angioplasty. The risk of adverse event in adjusted models for ODS cases was significantly lower than in GA cases (odds ratio: 0.66; 95% confidence interval: 0.45 to 0.95; p = 0.03). Total room time and case time were also significantly shorter (p < 0.001). Professional (charge ratio: 0.88; p < 0.001) and hospital (charge ratio: 0.84; p < 0.001) charges for ODS cases were also lower than those for GA cases.ConclusionsThis study demonstrates that clinical judgment can identify subjects in whom ODS is not associated with increased risk of adverse events. The use of ODS was associated with reduced case times and charges. In combination, these findings suggest that the selective use of ODS can allow for greater efficiency and higher value care without sacrificing safety.

Project description:OBJECTIVES:Sedation and neuromuscular blockade protocols in patients undergoing targeted temperature management after cardiac arrest address patient discomfort and manage shivering. These protocols vary widely between centers and may affect outcomes. DESIGN:Consecutive patients admitted to 20 centers after resuscitation from cardiac arrest were prospectively entered into the International Cardiac Arrest Registry between 2006 and 2016. Additional data about each center's sedation and shivering management practice were obtained via survey. Sedation and shivering practices were categorized as escalating doses of sedation and minimal or no neuromuscular blockade (sedation and shivering practice 1), sedation with continuous or scheduled neuromuscular blockade (sedation and shivering practice 2), or sedation with as-needed neuromuscular blockade (sedation and shivering practice 3). Good outcome was defined as Cerebral Performance Category score of 1 or 2. A logistic regression hierarchical model was created with two levels (patient-level data with standard confounders at level 1 and hospitals at level 2) and sedation and shivering practices as a fixed effect at the hospital level. The primary outcome was dichotomized Cerebral Performance Category at 6 months. SETTING:Cardiac arrest receiving centers in Europe and the United states from 2006 to 2016 PATIENTS:: Four-thousand two-hundred sixty-seven cardiac arrest patients 18 years old or older enrolled in the International Cardiac Arrest Registry. INTERVENTIONS:None. MEASUREMENTS AND MAIN RESULTS:The mean age was 62?±?15 years, 36% were female, 77% out-of-hospital arrests, and mean ischemic time was 24 (± 18) minutes. Adjusted odds ratio (for age, return of spontaneous circulation, location of arrest, witnessed, initial rhythm, bystander cardiopulmonary resuscitation, defibrillation, medical history, country, and size of hospital) was 1.13 (0.74-1.73; p = 0.56) and 1.45 (1.00-2.13; p = 0.046) for sedation and shivering practice 2 and sedation and shivering practice 3, respectively, referenced to sedation and shivering practice 1. CONCLUSION:Cardiac arrest patients treated at centers using as-needed neuromuscular blockade had increased odds of good outcomes compared with centers using escalating sedation doses and avoidance of neuromuscular blockade, after adjusting for potential confounders. These findings should be further investigated in prospective studies.

Project description:BackgroundThe association of near-infrared spectroscopy (NIRS) with various outcomes after pediatric cardiac surgery has been studied extensively. However, the role of NIRS in the prediction of cardiac arrest (CA) in children with heart disease has yet to be evaluated. We sought to determine if a model utilizing regional cerebral oximetry (rSO2c) and somatic oximetry (rSO2s) could predict CA in children admitted to a single-center pediatric cardiac intensive care unit (CICU).MethodsWe retrospectively reviewed 160 index CA events for patients admitted to our pediatric CICU between November 2010 and January 2019. We selected 711 control patients who did not have a cardiac arrest. Hourly data was collected from the electronic health record (EHR). We previously created a machine-learning algorithm to predict the risk of CA using EHR data. Univariable analysis was done on these variables, which we then used to create a multivariable logistic regression model. The outputs from the model were presented by odds ratio (OR) and 95% confidence interval (CI).ResultsWe created a multivariable model to evaluate the association of CA using five variables: arterial saturation (SpO2)- rSO2c difference, SpO2-rSO2s difference, heart rate, diastolic blood pressure, and vasoactive inotrope score. While the SpO2-rSO2c difference was not a significant contributor to the multivariable model, the SpO2-rSO2s difference was. The average SpO2-rSO2s difference cutoff with the best prognostic accuracy for CA was 29% [CI 26-31%]. In the multivariable model, a 10% increase in the SpO2-rSO2s difference was independently associated with increased odds of CA [OR 1.40 (1.18, 1.67), P < 0.001] at 1 h before CA. Our model predicted CA with an AUROC of 0.83 at 1 h before CA.ConclusionIn this single-center case-control study of children admitted to a pediatric CICU, we created a multivariable model utilizing hourly data from the EHR to predict CA. At 1 h before the event, for every 10% increase in the SpO2-rSO2s difference, the odds of cardiac arrest increased by 40%. These findings are important as the field explores ways to capitalize on the wealth of data at our disposal to improve patient care.

Project description:ObjectiveTo investigate the impact of probiotic Bifidobacterium longum ssp. infantis on the fecal microbiota and plasma cytokines in neonates with congenital heart disease.Study designSixteen infants with congenital heart disease were randomly assigned to receive either B. infantis (4.2 × 10(9) colony-forming units two times daily) or placebo for 8 weeks. Stool specimens from enrolled infants and from six term infants without heart disease were analyzed for microbial composition. Plasma cytokines were analyzed weekly in the infants with heart disease.ResultsHealthy control infants had increased total bacteria, total Bacteroidetes and total bifidobacteria compared to the infants with heart disease, but there were no significant differences between the placebo and probiotic groups. Plasma interleukin (IL)10, interferon (IFN)γ and IL1β levels were transiently higher in the probiotic group.ConclusionCongenital heart disease in infants is associated with dysbiosis. Probiotic B. infantis did not significantly alter the fecal microbiota. Alterations in plasma cytokines were found to be inconsistent.

Project description:BackgroundSedation and analgesia are recommended during targeted temperature management (TTM) after cardiac arrest, but there are few data to provide guidance on dosing to bedside clinicians. We evaluated differences in patient-level sedation and analgesia dosing in an international multicenter TTM trial to better characterize current practice and clinically important outcomes.MethodsA total 950 patients in the international TTM trial were randomly assigned to a TTM of 33 °C or 36 °C after resuscitation from cardiac arrest in 36 intensive care units. We recorded cumulative doses of sedative and analgesic drugs at 12, 24, and 48 h and normalized to midazolam and fentanyl equivalents. We compared number of medications used, dosing, and titration among centers by using multivariable models, including common severity of illness factors. We also compared dosing with time to awakening, incidence of clinical seizures, and survival.ResultsA total of 614 patients at 18 centers were analyzed. Propofol (70%) and fentanyl (51%) were most frequently used. The average dosages of midazolam and fentanyl equivalents were 0.13 (0.07, 0.22) mg/kg/h and 1.16 (0.49, 1.81) µg/kg/h, respectively. There were significant differences in number of medications (p < 0.001), average dosages (p < 0.001), and titration at all time points between centers (p < 0.001), and the outcomes of patients in these centers were associated with all parameters described in the multivariate analysis, except for a difference in the titration of sedatives between 12 and 24 h (p = 0.40). There were associations between higher dosing at 48 h (p = 0.003, odds ratio [OR] 1.75) and increased titration of analgesics between 24 and 48 h (p = 0.005, OR 4.89) with awakening after 5 days, increased titration of sedatives between 24 and 48 h with awakening after 5 days (p < 0.001, OR > 100), and increased titration of sedatives between 24 and 48 h with a higher incidence of clinical seizures in the multivariate analysis (p = 0.04, OR 240). There were also significant associations between decreased titration of analgesics and survival at 6 months in the multivariate analysis (p = 0.048).ConclusionsThere is significant variation in choice of drug, dosing, and titration when providing sedation and analgesics between centers. Sedation and analgesia dosing and titration were associated with delayed awakening, incidence of clinical seizures, and survival, but the causal relation of these findings cannot be proven.

Project description:ImportanceIn 2011, critical congenital heart disease was added to the US Recommended Uniform Screening Panel for newborns, but whether state implementation of screening policies has been associated with infant death rates is unknown.ObjectiveTo assess whether there was an association between implementation of state newborn screening policies for critical congenital heart disease and infant death rates.Design, Setting, and ParticipantsObservational study with group-level analyses. A difference-in-differences analysis was conducted using the National Center for Health Statistics' period linked birth/infant death data set files for 2007-2013 for 26?546?503 US births through June 30, 2013, aggregated by month and state of birth.ExposuresState policies were classified as mandatory or nonmandatory (including voluntary policies and mandates that were not yet implemented). As of June 1, 2013, 8 states had implemented mandatory screening policies, 5 states had voluntary screening policies, and 9 states had adopted but not yet implemented mandates.Main Outcomes and MeasuresNumbers of early infant deaths (between 24 hours and 6 months of age) coded for critical congenital heart disease or other/unspecified congenital cardiac causes for each state-month birth cohort.ResultsBetween 2007 and 2013, there were 2734 deaths due to critical congenital heart disease and 3967 deaths due to other/unspecified causes. Critical congenital heart disease death rates in states with mandatory screening policies were 8.0 (95% CI, 5.4-10.6) per 100?000 births (n?=?37) in 2007 and 6.4 (95% CI, 2.9-9.9) per 100?000 births (n?=?13) in 2013 (for births by the end of July); for other/unspecified cardiac causes, death rates were 11.7 (95% CI, 8.6-14.8) per 100?000 births in 2007 (n?=?54) and 10.3 (95% CI, 5.9-14.8) per 100?000 births (n?=?21) in 2013. Early infant deaths from critical congenital heart disease through December 31, 2013, decreased by 33.4% (95% CI, 10.6%-50.3%), with an absolute decline of 3.9 (95% CI, 3.6-4.1) deaths per 100?000 births after states implemented mandatory screening compared with prior periods and states without screening policies. Early infant deaths from other/unspecified cardiac causes declined by 21.4% (95% CI, 6.9%-33.7%), with an absolute decline of 3.5 (95% CI, 3.2-3.8) deaths per 100?000 births. No significant decrease was associated with nonmandatory screening policies.Conclusions and RelevanceStatewide implementation of mandatory policies for newborn screening for critical congenital heart disease was associated with a significant decrease in infant cardiac deaths between 2007 and 2013 compared with states without these policies.
