Acute kidney injury after out of hospital pediatric cardiac arrest.

ABSTRACT: IMPORTANCE:Many 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. OBJECTIVE:The 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. DESIGN:A post hoc secondary analysis of data from the Therapeutic Hypothermia after Pediatric Cardiac Arrest Out-of-Hospital (THAPCA-OH) trial. SETTING:Thirty-six pediatric intensive care units in the United States and Canada. PARTICIPANTS:Of 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 MEASURES:Primary 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. RESULTS:Of 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?

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:BackgroundAcute kidney injury (AKI) is a frequent complication in cardiac arrest survivors and associated with adverse outcome. It remains unclear whether the incidence of AKI increases after the post-cardiac arrest contrast administration for coronary angiography and whether this depends on timing of angiography. Aim of this study was to investigate whether early angiography is associated with increased development of AKI compared to deferred angiography in out-of-hospital cardiac arrest (OHCA) survivors.MethodsIn this retrospective multicenter cohort study, we investigated whether early angiography (within 2 h) after OHCA was non-inferior to deferred angiography regarding the development of AKI. We used an absolute difference of 5% as the non-inferiority margin. Primary non-inferiority analysis was done by calculating the risk difference with its 90% confidence interval (CI) using a generalized linear model for a binary outcome. As a sensitivity analysis, we repeated the primary analysis using propensity score matching. A multivariable model was built to identify predictors of acute kidney injury.ResultsA total of 2375 patients were included from 2009 until 2018, of which 1148 patients were treated with early coronary angiography and 1227 patients with delayed or no angiography. In the early angiography group 18.5% of patients developed AKI after OHCA and 24.1% in the deferred angiography group. Risk difference was - 3.7% with 90% CI ranging from - 6.7 to - 0.7%, indicating non-inferiority of early angiography. The sensitivity analysis using propensity score matching showed accordant results, but no longer non-inferiority of early angiography. The factors time to return of spontaneous circulation (odds ratio [OR] 1.12, 95% CI 1.06-1.19, p < 0.001), the (not) use of angiotensin-converting enzyme inhibitor or angiotensin II receptor blocker (OR 0.20, 95% CI 0.04-0.91, p = 0.04) and baseline creatinine (OR 1.05, 95% CI 1.03-1.07, p < 0.001) were found to be independently associated with the development of AKI.ConclusionsAlthough AKI occurred in approximately 20% of OHCA patients, we found that early angiography was not associated with a higher AKI incidence than a deferred angiography strategy. The present results implicate that it is safe to perform early coronary angiography with respect to the risk of developing AKI after OHCA.

Project description:BACKGROUND:Acute kidney injury (AKI) after out-of-hospital cardiac arrest (OHCA) is a well-known predictor for mortality. However, the natural course of AKI including recovery rate after OHCA is uncertain. This study investigated the clinical course of AKI after OHCA and determined whether recovery from AKI impacted the outcomes of OHCA. METHODS:This retrospective multicentre cohort study included adult OHCA patients treated with targeted temperature management (TTM) between January 2016 and December 2017. AKI was diagnosed using the Kidney Disease: Improving Global Outcomes criteria. The primary outcome was the recovery rate after AKI and its association with survival and good neurological outcome at discharge. RESULTS:A total of 3697 OHCA patients from six hospitals were screened and 275 were finally included. AKI developed in 175/275 (64%) patients and 69/175 (39%) patients recovered from AKI. In most cases, AKI developed within three days of return of spontaneous circulation [155/175 (89%), median time to AKI development 1 (1-2) day] and patients recovered within seven days of return of spontaneous circulation [59/69 (86%), median time to AKI recovery 3 (2-7) days]. Duration of AKI was significantly longer in the AKI non-recovery group than in the AKI recovery group [5 (2-9) vs. 1 (1-5) days; P?<?0.001]. Most patients were diagnosed with AKI stage 1 initially [120/175 (69%)]. However, the number of stage 3 AKI patients increased from 30/175 (17%) to 77/175 (44%) after the initial diagnosis of AKI. The rate of survival discharge was significantly higher in the AKI recovery group than in the AKI non-recovery group [45/69 (65%) vs. 17/106 (16%); P?<?0.001]. Recovery from AKI was a potent predictor of survival and good neurological outcome at discharge in the multivariate analysis (adjusted odds ratio, 8.308; 95% confidence interval, 3.120-22.123; P?<?0.001 and adjusted odds ratio, 36.822; 95% confidence interval, 4.097-330.926; P?=?0.001). CONCLUSIONS:In our cohort of adult OHCA patients treated with TTM (n?=?275), the recovery rate from AKI after OHCA was 39%, and recovery from AKI was a potent predictor of survival and good neurological outcome at discharge.
