Sonographic cardiac standstill during adult cardiac arrest is associated with failure to get return to spontaneous circulation. This report documents 3 children whose cardiac function returned after standstill with extracorporeal membranous oxygenation. Sonographic cardiac standstill may not predict cardiac death in children. ...[more]

Project description:This case describes and depicts cardiac standstill with thrombosed blood within the chambers of the heart. This was likely due to stasis of blood from a prolonged no-flow state. After viewing this ultrasound finding, the decision was made to halt resuscitative efforts in this case of a patient in cardiac arrest.

Project description:OBJECTIVES:In-hospital cardiac arrest occurs in 2.6-6% of children with cardiac disease and is associated with significant morbidity and mortality. Much remains unknown about cardiac arrest in pediatric cardiac ICUs; therefore, we aimed to describe cardiac arrest epidemiology in a contemporary multicenter cardiac ICU cohort. DESIGN:Retrospective analysis within the Pediatric Cardiac Critical Care Consortium clinical registry. SETTING:Cardiac ICUs within 23 North American hospitals. PATIENTS:All cardiac medical and surgical patients admitted from August 2014 to July 2016. INTERVENTIONS:None. MEASUREMENTS AND MAIN RESULTS:There were 15,908 cardiac ICU encounters (6,498 medical, 9,410 surgical). 3.1% had cardiac arrest; rate was 4.8 cardiac arrest per 1,000 cardiac ICU days. Medical encounters had 50% higher rate of cardiac arrest compared with surgical encounters. Observed (unadjusted) cardiac ICU cardiac arrest prevalence varied from 1% to 5.5% among the 23 centers; cardiac arrest per 1,000 cardiac ICU days varied from 1.1 to 10.4. Over half cardiac arrest occur within 48 hours of admission. On multivariable analysis, prematurity, neonatal age, any Society of Thoracic Surgeons preoperative risk factor, and Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery mortality category 4, 5 had strongest association with surgical encounter cardiac arrest. In medical encounters, independent cardiac arrest risk factors were acute heart failure, prematurity, lactic acidosis greater than 3 mmol/dL, and invasive ventilation 1 hour after admission. Median cardiopulmonary resuscitation duration was 10 minutes, return of spontaneous circulation occurred in 64.5%, extracorporeal cardiopulmonary resuscitation in 27.2%. Unadjusted survival was 53.2% in encounters with cardiac arrest versus 98.2% without. Medical encounters had lower survival after cardiac arrest (37.7%) versus surgical encounters (62.5%); Norwood patients had less than half the survival after cardiac arrest (35.6%) compared with all others. Unadjusted survival after cardiac arrest varied greatly among 23 centers. CONCLUSIONS:We provide contemporary epidemiologic and outcome data for cardiac arrest occurring in the cardiac ICU from a multicenter clinical registry. As detailed above, we highlight high-risk patient cohorts and periods of time that may serve as targets for research and quality improvement initiatives aimed at cardiac arrest prevention.

Project description:To analyze functional performance measures collected prospectively during the conduct of a clinical trial that enrolled children (up to age 18 yr old), resuscitated after out-of-hospital cardiac arrest, who were at high risk of poor outcomes.Children with Glasgow Motor Scale score less than 5, within 6 hours of resuscitation, were enrolled in a clinical trial that compared two targeted temperature management interventions (THAPCA-OH, NCT00878644). The primary outcome, 12-month survival with Vineland Adaptive Behavior Scale, second edition, score greater or equal to 70, did not differ between groups.Thirty-eight North American PICUs.Two hundred ninety-five children were enrolled; 270 of 295 had baseline Vineland Adaptive Behavior Scale, second edition, scores greater or equal to 70; 87 of 270 survived 1 year.Targeted temperatures were 33.0°C and 36.8°C for hypothermia and normothermia groups.Baseline measures included Vineland Adaptive Behavior Scale, second edition, Pediatric Cerebral Performance Category, and Pediatric Overall Performance Category. Pediatric Cerebral Performance Category and Pediatric Overall Performance Category were rescored at hospital discharges; all three were scored at 3 and 12 months. In survivors with baseline Vineland Adaptive Behavior Scale, second edition scores greater or equal to 70, we evaluated relationships of hospital discharge Pediatric Cerebral Performance Category with 3- and 12-month scores and between 3- and 12-month Vineland Adaptive Behavior Scale, second edition, scores. Hospital discharge Pediatric Cerebral Performance Category scores strongly predicted 3- and 12-month Pediatric Cerebral Performance Category (r = 0.82 and 0.79; p < 0.0001) and Vineland Adaptive Behavior Scale, second edition, scores (r = -0.81 and -0.77; p < 0.0001). Three-month Vineland Adaptive Behavior Scale, second edition, scores strongly predicted 12-month performance (r = 0.95; p < 0.0001). Hypothermia treatment did not alter these relationships.In comatose children, with Glasgow Motor Scale score less than 5 in the initial hours after out-of-hospital cardiac arrest resuscitation, function scores at hospital discharge and at 3 months predicted 12-month performance well in the majority of survivors.

Project description:ImportanceMany children with return of spontaneous circulation (ROSC) following cardiac arrest (CA) experience acute kidney injury (AKI). The impact of therapeutic hypothermia on the epidemiology of post-CA AKI in children has not been fully investigated.ObjectiveThe study aims were to: 1) describe the prevalence of severe AKI in comatose children following out-of-hospital CA (OHCA), 2) identify risk factors for severe AKI, 3) evaluate the impact of therapeutic hypothermia on the prevalence of severe AKI, and 4) evaluate the association of severe AKI with survival and functional outcomes.DesignA post hoc secondary analysis of data from the Therapeutic Hypothermia after Pediatric Cardiac Arrest Out-of-Hospital (THAPCA-OH) trial.SettingThirty-six pediatric intensive care units in the United States and Canada.ParticipantsOf 282 eligible subjects with an initial creatinine obtained within 24 h of randomization, 148 were randomized to therapeutic hypothermia and 134 were randomized to therapeutic normothermia.Main outcomes and measuresPrimary outcome was prevalence of severe AKI, as defined by stage 2 and 3 Kidney Disease Improving Global Outcomes (KDIGO) consensus definition; secondary outcome was survival with a favorable neurobehavioral outcome. For this study, risk factors and outcomes were compared between those with/without severe AKI.ResultsOf the 282 subjects enrolled, 180 (64%) developed AKI of which 117 (41% of all enrolled) developed severe AKI. Multivariable modeling found younger age, longer duration of chest compressions, higher lactate level at time of temperature intervention and higher number of vasoactive agents through day 1 of intervention associated with severe AKI. There was no difference in severe AKI between therapeutic hypothermia (39.9%) and therapeutic normothermia (43.3%) groups (p = 0.629). Survival was lower in those with severe AKI at 28 days (21% vs no severe AKI 49%, p < 0.001) and 12 months (21% vs no severe AKI 42%, p < 0.001). One year survival with favorable functional outcome was lower in those with severe AKI.Conclusions and relevanceSevere AKI occurs frequently in children with ROSC after OHCA, especially in younger children and those with higher initial lactates and hemodynamic support. Severe AKI was associated with worse survival and functional outcome. Therapeutic hypothermia did not reduce the incidence of severe AKI.

Project description:ObjectivesThe objective of this study was to associate ventilation rates during in-hospital cardiopulmonary resuscitation with 1) arterial blood pressure during cardiopulmonary resuscitation and 2) survival outcomes.DesignProspective, multicenter observational study.SettingPediatric and pediatric cardiac ICUs of the Collaborative Pediatric Critical Care Research Network.PatientsIntubated children (≥ 37 wk gestation and < 19 yr old) who received at least 1 minute of cardiopulmonary resuscitation.InterventionsNone.Measurements and main resultsArterial blood pressure and ventilation rate (breaths/min) were manually extracted from arterial line and capnogram waveforms. Guideline rate was defined as 10 ± 2 breaths/min; high ventilation rate as greater than or equal to 30 breaths/min in children less than 1 year old, and greater than or equal to 25 breaths/min in older children. The primary outcome was survival to hospital discharge. Regression models using Firth penalized likelihood assessed the association between ventilation rates and outcomes. Ventilation rates were available for 52 events (47 patients). More than half of patients (30/47; 64%) were less than 1 year old. Eighteen patients (38%) survived to discharge. Median event-level average ventilation rate was 29.8 breaths/min (interquartile range, 23.8-35.7). No event-level average ventilation rate was within guidelines; 30 events (58%) had high ventilation rates. The only significant association between ventilation rate and arterial blood pressure occurred in children 1 year old or older and was present for systolic blood pressure only (-17.8 mm Hg/10 breaths/min; 95% CI, -27.6 to -8.1; p < 0.01). High ventilation rates were associated with a higher odds of survival to discharge (odds ratio, 4.73; p = 0.029). This association was stable after individually controlling for location (adjusted odds ratio, 5.97; p = 0.022), initial rhythm (adjusted odds ratio, 3.87; p = 0.066), and time of day (adjusted odds ratio, 4.12; p = 0.049).ConclusionsIn this multicenter cohort, ventilation rates exceeding guidelines were common. Among the range of rates delivered, higher rates were associated with improved survival to hospital discharge.

Project description:Background and aimsCardiac arrest (CA) in children is a major public health problem. Thanks to advances in cardiopulmonary resuscitation (CPR) guidelines and teaching skills, results in children have improved. However, pediatric CA has a very high mortality. In the treatment of in-hospital CA there are still multiple controversies. The objective of this study is to develop a multicenter and international registry of in-hospital pediatric cardiac arrest including the diversity of management in different clinical and social contexts. Participation in this register will enable the evaluation of the diagnosis of CA, CPR and post-resuscitation care and its influence in survival and neurological prognosis.MethodsAn intrahospital CA data recording protocol has been designed following the Utstein model. Database is hosted according to European legislation regarding patient data protection. It is drafted in English and Spanish. Invitation to participate has been sent to Spanish, European and Latinamerican hospitals. Variables included, asses hospital characteristics, the resuscitation team, patient's demographics and background, CPR, post-resuscitation care, mortality, survival and long-term evolution. Survival at hospital discharge will be evaluated as a primary outcome and survival with good neurological status as a secondary outcome, analyzing the different factors involved in them. The study design is prospective, observational registry of a cohort of pediatric CA.ConclusionsThis study represents the development of a registry of in-hospital CA in childhood. Its development will provide access to CPR data in different hospital settings and will allow the analysis of current controversies in the treatment of pediatric CA and post-resuscitation care. The results may contribute to the development of further international recommendations. Trial register: ClinicalTrials.gov Identifier: NCT04675918.

Project description:This study evaluated whether inter-hospital transfer (IHT) after the return of spontaneous circulation (ROSC) was associated with poor neurological outcomes after 6 months in post-cardiac-arrest patients treated with targeted temperature management (TTM). We used data from the Korean Hypothermia Network prospective registry from November 2015 to December 2018. These out-of-hospital cardiac arrest (OHCA) patients had either received post-cardiac arrest syndrome (PCAS) care at the same hospital or had been transferred from another hospital after ROSC. The primary endpoint was the neurological outcome 6 months after cardiac arrest. Subgroup analyses were performed to determine differences in the time from ROSC to TTM induction according to the electrocardiography results after ROSC. We enrolled 1326 patients. There were no significant differences in neurological outcomes between the direct visit and IHT groups. In patients without ST elevation, the mean time to TTM was significantly shorter in the direct visit group than in the IHT group. IHT after achieving ROSC was not associated with neurologic outcomes after 6 months in post-OHCA patients treated with TTM, even though TTM induction was delayed in transferred patients.

Project description:AIM:The primary aim of this study was to evaluate the association between chest compression rates and 1) arterial blood pressure and 2) survival outcomes during pediatric in-hospital cardiopulmonary resuscitation (CPR). METHODS:Prospective observational study of children ?37 weeks gestation and <19 years old who received CPR in an intensive care unit (ICU) as part of the Pediatric Intensive Care Unit Quality of CPR Study (PICqCPR) of the Collaborative Pediatric Critical Care Research Network (CPCCRN). Arterial blood pressure and compression rate were determined from manually extracted arterial line waveform data during the first 10?min of CPR. The primary outcome was survival to hospital discharge. Modified Poisson regression models assessed the association between rate categories (80-<100, 100-120 [Guidelines], >120-140, >140) and outcomes. RESULTS:Compression rate data were available for 164 patients. More than half (98/164; 60%) were <1?year old. Return of circulation was achieved in 148/164 (90%); survival to hospital discharge in 77/164 (47%). Percentage of events with average rate within Guidelines was 32.9%. Compared to Guidelines, higher rate categories were associated with lower systolic blood pressures (>120-140, p?=?0.010; >140, p?=?0.077), but not survival. A rate between 80-<100 per minute was associated with a higher rate of survival to hospital discharge (aRR 1.92, CI95 1.13, 3.29, p?=?0.017) and survival with favorable neurological outcome (aRR 2.12, CI95 1.09, 4.13, p?=?0.027) compared to Guidelines. CONCLUSION:Non-compliance with compression rate Guidelines was common in this multicenter cohort. Among ICU patients, slightly lower rates were associated with improved outcomes compared to Guidelines.

Project description:Improved survival after cardiac arrest has placed greater emphasis on neurologic resuscitation. The purpose of this pilot study was to evaluate the relationship between cerebrovascular autoregulation and neurologic outcomes after pediatric cardiac arrest.Children resuscitated from cardiac arrest had autoregulation monitoring during the first 72h after return of circulation with an index derived from near-infrared spectroscopy in a pilot study. The range of mean arterial blood pressure (MAP) with optimal vasoreactivity (MAPOPT) was identified. The area under the curve (AUC) of the time spent with MAP below MAPOPT and MAP deviation below MAPOPT was calculated. Neurologic outcome measures included placement of a new tracheostomy or gastrostomy, death from a primary neurologic etiology (brain death or withdrawal of support for neurologic futility), and change in the Pediatric Cerebral Performance Category score (?PCPC).Thirty-six children were monitored. Among children who did not require extracorporeal membrane oxygenation (ECMO), children who received a tracheostomy/gastrostomy had greater AUC during the second 24h after resuscitation than those who did not (P=0.04; n=19). Children without ECMO who died from a neurologic etiology had greater AUC during the first 48h than did those who lived or died from cardiovascular failure (P=0.04; n=19). AUC below MAPOPT was not associated with ?PCPC when children with or without ECMO were analyzed separately.Deviation from the blood pressure with optimal autoregulatory vasoreactivity may predict poor neurologic outcomes after pediatric cardiac arrest. This experimental autoregulation monitoring technique may help individualize blood pressure management goals after resuscitation.

Project description:IMPORTANCE:Delay in administration of the first epinephrine dose is associated with decreased survival among adults after in-hospital, nonshockable cardiac arrest. Whether this association is true in the pediatric in-hospital cardiac arrest population remains unknown. OBJECTIVE:To determine whether time to first epinephrine dose is associated with outcomes in pediatric in-hospital cardiac arrest. DESIGN, SETTING AND PARTICIPANTS:We performed an analysis of data from the Get With the Guidelines-Resuscitation registry. We included US pediatric patients (age <18 years) with an in-hospital cardiac arrest and an initial nonshockable rhythm who received at least 1 dose of epinephrine. A total of 1558 patients (median age, 9 months [interquartile range [IQR], 13 days-5 years]) were included in the final cohort. EXPOSURE:Time to epinephrine, defined as time in minutes from recognition of loss of pulse to the first dose of epinephrine. MAIN OUTCOMES AND MEASURES:The primary outcome was survival to hospital discharge. Secondary outcomes included return of spontaneous circulation (ROSC), survival at 24 hours, and neurological outcome. A favorable neurological outcome was defined as a score of 1 to 2 on the Pediatric Cerebral Performance Category scale. RESULTS:Among the 1558 patients, 487 (31.3%) survived to hospital discharge. The median time to first epinephrine dose was 1 minute (IQR, 0-4; range, 0-20; mean [SD], 2.6 [3.4] minutes). Longer time to epinephrine administration was associated with lower risk of survival to discharge in multivariable analysis (multivariable-adjusted risk ratio [RR] per minute delay, 0.95 [95% CI, 0.93-0.98]). Longer time to epinephrine administration was also associated with decreased risk of ROSC (multivariable-adjusted RR per minute delay, 0.97 [95% CI, 0.96-0.99]), decreased risk of survival at 24 hours (multivariable-adjusted RR per minute delay, 0.97 [95% CI, 0.95-0.99]), and decreased risk of survival with favorable neurological outcome (multivariable-adjusted RR per minute delay, 0.95 [95% CI, 0.91-0.99]). Patients with time to epinephrine administration of longer than 5 minutes (233/1558) compared with those with time to epinephrine of 5 minutes or less (1325/1558) had lower risk of in-hospital survival to discharge (21.0% [49/233] vs 33.1% [438/1325]; multivariable-adjusted RR, 0.75 [95% CI, 0.60-0.93]; P?=?.01). CONCLUSIONS AND RELEVANCE:Among children with in-hospital cardiac arrest with an initial nonshockable rhythm who received epinephrine, delay in administration of epinephrine was associated with decreased chance of survival to hospital discharge, ROSC, 24-hour survival, and survival to hospital discharge with a favorable neurological outcome.
