Peri-arrest bolus epinephrine practices amongst pediatric resuscitation experts.
Ontology highlight
ABSTRACT: Aim
To describe current practices of peri-arrest bolus epinephrine use amongst pediatric resuscitation experts in a multinational survey.Methods
A 9-question survey was developed and electronically distributed to pediatric critical care physicians who are site investigators for the Pediatric Resuscitation Quality Collaborative (pediRES-Q) network. Institutional demographics were collected through the American Hospital Association 2018 Annual Survey and linked to responses. Descriptive statistics were used to characterize closed-ended responses, and qualitative content analysis to analyze open-ended responses.Results
Of the 63 collaborative members invited to participate, 49 (78%) responded, representing 35 institutions in 9 countries. Forty-six of the 49 respondents (94%) reported that they would consider using peri-arrest bolus epinephrine during critical situations in patients not requiring cardiopulmonary resuscitation. Initial dosing strategies ranged from 0.1mcg/kg to 10mcg/kg, with the most commonly reported initial dose of 1mcg/kg by 25 of the 37 (68%) respondents who answered this question. Three of the 49 (6%) participants indicated that they would generally avoid using peri-arrest bolus epinephrine, citing lack of evidence to support its use.Conclusions
In this multinational survey of pediatric resuscitation experts, endorsement of peri-arrest bolus epinephrine use was nearly universal, though a few clinicians cited lack of evidence to support this practice. There was a 100-fold difference in the range of initial weight-based doses reported, as well as a minority of clinicians who reported using non-weight-based dosing. Further research is needed to determine best practices, standardization of initial dosing, clinical factors that may warrant dosing modifications and associations with clinically important outcomes.

Project description:AimTo quantify the physiologic effects of pre-arrest bolus dilute epinephrine in the pediatric intensive care unit.MethodsPatients <18 years old and ≥37 weeks gestation who received an intravenous bolus of dilute epinephrine (10 mcg/mL) in the pediatric intensive care units at our institution from January 2011 to March 2017 were retrospectively identified. Patients were excluded if doses exceeded 20 mcg/kg, or under the following circumstances: orders limiting resuscitation, extracorporeal membrane oxygenation, active chest compressions, simultaneous administration of other blood pressure-altering interventions or documented normotension prior to epinephrine. The primary outcome was change in systolic blood pressure within 5 min of epinephrine. Patients were categorized as non-responders if the change in systolic blood pressure was ≤10 mmHg.ResultsOne hundred forty-four patients were analyzed. The median index dose was 0.7 mcg/kg (IQR, 0.3-2.0), and the mean increase in systolic blood pressure was 31 mmHg (95% CI, 25-36; P < 0.001). Thirty-nine (27%) patients were classified as non-responders. Compared to responders, non-responders had higher rates of cardiac arrest or extracorporeal membrane oxygenation within 6 h (26% vs 10%; relative risk, 2.69; 95% CI, 1.21-5.97; P = 0.03), and had higher in-hospital mortality (51% vs 21%; relative risk, 2.45; 95% CI, 1.51-3.96; P < 0.001).ConclusionsIn the majority of pre-arrest pediatric patients, bolus dilute epinephrine resulted in an increase in systolic blood pressure, and lack of blood pressure response was associated with poor outcomes. Optimal dosing of dilute epinephrine remains unclear.

Project description:The aim of this study was to examine the use of volumetric capnography monitoring to assess cardiopulmonary resuscitation (CPR) effectiveness by correlating it with cardiac output (CO), and to evaluate the effect of epinephrine boluses on both end-tidal carbon dioxide (EtCO 2 ) and the volume of CO 2 elimination (VCO 2 ) in a swine ventricular fibrillation cardiac arrest model. Planned secondary analysis of data collected to investigate the use of noninvasive monitors in a pediatric swine ventricular fibrillation cardiac arrest model was performed. Twenty-eight ventricular fibrillatory arrests with open cardiac massage were conducted. During CPR, EtCO 2 and VCO 2 had strong correlation with CO, measured as a percentage of baseline pulmonary blood flow, with correlation coefficients of 0.83 ( p < 0.001) and 0.53 ( p = 0.018), respectively. However, both EtCO 2 and VCO 2 had weak and nonsignificant correlation with diastolic blood pressure during CPR 0.30 ( p = 0.484) (95% confidence interval [CI], -0.51-0.83) and 0.25 ( p = 0.566) (95% CI, -0.55-0.81), respectively. EtCO 2 and VCO 2 increased significantly after the first epinephrine bolus without significant change in CO. The correlations between EtCO 2 and VCO 2 and CO were weak 0.20 ( p = 0.646) (95% CI, -0.59-0.79), and 0.27 ( p = 0.543) (95% CI, -0.54-0.82) following epinephrine boluses. Continuous EtCO 2 and VCO 2 monitoring are potentially useful metrics to ensure effective CPR. However, transient epinephrine administration by boluses might confound the use of EtCO 2 and VCO 2 to guide chest compression.

Project description:Epinephrine is the principal resuscitation therapy for pediatric cardiac arrest (CA). Clinical data suggest that although epinephrine increases the rate of resuscitation, it fails to improve neurological outcome, possibly secondary to reductions in microvascular flow. We characterized the effect of epinephrine vs. placebo administered at resuscitation from pediatric asphyxial CA on microvascular and macrovascular cortical perfusion assessed using in vivo multiphoton microscopy and laser speckle flowmetry, respectively, and on brain tissue oxygenation (PbO2), behavioral outcomes, and neuropathology in 16-18-day-old rats. Epinephrine-treated rats had a more rapid return of spontaneous circulation and brisk immediate cortical reperfusion during 1-3 min post-CA vs. placebo. However, at the microvascular level, epinephrine-treated rats had penetrating arteriole constriction and increases in both capillary stalling (no-reflow) and cortical capillary transit time 30-60 min post-CA vs. placebo. Placebo-treated rats had increased capillary diameters post-CA. The cortex was hypoxic post-CA in both groups. Epinephrine treatment worsened reference memory performance vs. shams. Hippocampal neuron counts did not differ between groups. Resuscitation with epinephrine enhanced immediate reperfusion but produced microvascular alterations during the first hour post-resuscitation, characterized by vasoconstriction, capillary stasis, prolonged cortical transit time, and absence of compensatory cortical vasodilation. Targeted therapies mitigating the deleterious microvascular effects of epinephrine are needed.

Project description:ImportanceDelay 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.ObjectiveTo determine whether time to first epinephrine dose is associated with outcomes in pediatric in-hospital cardiac arrest.Design, setting and participantsWe 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.ExposureTime to epinephrine, defined as time in minutes from recognition of loss of pulse to the first dose of epinephrine.Main outcomes and measuresThe 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.ResultsAmong 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 relevanceAmong 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.

Project description:ObjectivesWhile most pediatric coronavirus disease 2019 cases are not life threatening, some children have severe disease requiring emergent resuscitative interventions. Resuscitation events present risks to healthcare provider safety and the potential for compromised patient care. Current resuscitation practices and policies for children with suspected/confirmed coronavirus disease 2019 are unknown.DesignMulti-institutional survey regarding inpatient resuscitation practices during the coronavirus disease 2019 pandemic.SettingInternet-based survey.SubjectsU.S. PICU representatives (one per institution) involved in resuscitation system planning and oversight.InterventionsNone.Measurements and main resultsOf 130 institutions surveyed, 78 (60%) responded. Forty-eight centers (62%) had admitted coronavirus disease 2019 patients; 26 (33%) reported code team activation for patients with suspected/confirmed coronavirus disease 2019. Sixty-seven respondents (86%) implemented changes to inpatient emergency response systems. The most common changes were as follows: limited number of personnel entering patient rooms (75; 96%), limited resident involvement (71; 91%), and new or refined team roles (74; 95%). New or adapted technology is being used for coronavirus disease 2019 resuscitations in 58 centers (74%). Most institutions (57; 73%) are using enhanced personal protective equipment for all coronavirus disease 2019 resuscitation events; 18 (23%) have personal protective equipment policies dependent on the performance of aerosol generating procedures. Due to coronavirus disease 2019, most respondents are intubating earlier during cardiopulmonary resuscitation (56; 72%), utilizing video laryngoscopy (67; 86%), pausing chest compressions during laryngoscopy (56; 72%), and leaving patients connected to the ventilator during cardiopulmonary resuscitation (56; 72%). Responses were varied regarding airway personnel, prone cardiopulmonary resuscitation, ventilation strategy during cardiopulmonary resuscitation without an airway in place, and extracorporeal cardiopulmonary resuscitation. Most institutions (46; 59%) do not have policies regarding limitations of resuscitation efforts in coronavirus disease 2019 patients.ConclusionsMost U.S. pediatric institutions rapidly adapted their resuscitation systems and practices in response to the coronavirus disease 2019 pandemic. Changes were commonly related to team members and roles, personal protective equipment, and airway and breathing management, reflecting attempts to balance quality resuscitation with healthcare provider safety.

Project description:Background and objectivesPatients on maintenance dialysis with in-hospital cardiac arrest have been reported to have worse outcomes relative to those not on dialysis; however, it is unknown if poor outcomes are related to the quality of resuscitation. Using the Get With The Guidelines-Resuscitation (GWTG-R) registry, we examined processes of care and outcomes of in-hospital cardiac arrest for patients on maintenance dialysis compared with nondialysis patients.Design, setting, participants, & measurementsWe used GWTG-R data linked to Centers for Medicare and Medicaid data to identify patients with ESKD receiving maintenance dialysis from 2000 to 2012. We then case-matched adult patients on maintenance dialysis to nondialysis patients in a 1:3 ratio on the basis of age, sex, race, hospital, and year of arrest. Logistic regression models with generalized estimating equations were used to assess the association of in-hospital cardiac arrest and outcomes by dialysis status.ResultsAfter matching, there were a total of 31,144 GWTG-R patients from 372 sites, of which 8498 (27%) were on maintenance dialysis. Patients on maintenance dialysis were less likely to have a shockable initial rhythm (20% versus 21%) and less likely to be within the intensive care unit at the time of arrest (46% versus 47%) compared with nondialysis patients; they also had lower composite scores for resuscitation quality (89% versus 90%) and were less likely to have defibrillation within 2 minutes (54% versus 58%). After adjustment, patients on maintenance dialysis had similar adjusted odds of survival to discharge (odds ratio [OR], 1.05; 95% confidence interval [95% CI], 0.97 to 1.13), better acute survival (OR, 1.33; 95% CI, 1.26 to 1.40), and were more likely to have favorable neurologic status (OR, 1.12; 95% CI, 1.04 to 1.22) compared with nondialysis patients.ConclusionsAlthough there appears to be opportunities to improve the quality of in-hospital cardiac arrest care for among those on maintenance dialysis, survival to discharge was similar for these patients compared with nondialysis patients.

Project description:AimCompare vasopressin to a second dose of epinephrine as rescue therapy after ineffective initial doses of epinephrine in diverse models of pediatric in-hospital cardiac arrest.Methods67 one- to three-month old female swine (10-30 kg) in six experimental cohorts from one laboratory received hemodynamic-directed CPR, a resuscitation method where high quality chest compressions are provided and vasopressor administration is titrated to coronary perfusion pressure (CoPP) ≥20 mmHg. Vasopressors are given when CoPP is <20 mmHg, in sequences of two doses of 0.02 mg/kg epinephrine separated by minimum one-minute, then a rescue dose of 0.4 U/kg vasopressin followed by minimum two-minutes. Invasive measurements were used to evaluate and compare the hemodynamic and neurologic effects of each vasopressor dose.ResultsIncreases in CoPP and cerebral blood flow (CBF) were greater with vasopressin rescue than epinephrine rescue (CoPP: +8.16 [4.35, 12.06] mmHg vs. + 5.43 [1.56, 9.82] mmHg, p = 0.02; CBF: +14.58 [-0.05, 38.12] vs. + 0.00 [-0.77, 18.24] perfusion units (PFU), p = 0.005). Twenty animals (30%) failed to achieve CoPP ≥20 mmHg after two doses of epinephrine; 9/20 (45%) non-responders achieved CoPP ≥20 mmHg after vasopressin. Among all animals, the increase in CBF was greater with vasopressin (+14.58 [-0.58, 38.12] vs. 0.00 [-0.77, 18.24] PFU, p = 0.005).ConclusionsCoPP and CBF rose significantly more after rescue vasopressin than after rescue epinephrine. Importantly, CBF increased after vasopressin rescue, but not after epinephrine rescue. In the 30% that failed to meet CoPP of 20 mmHg after two doses of epinephrine, 45% achieved target CoPP with a single rescue vasopressin dose.

Project description:ImportanceAlthough survival of patients with in-hospital cardiac arrest varies markedly among hospitals, specific resuscitation practices that distinguish sites with higher cardiac arrest survival rates remain unknown.ObjectiveTo identify resuscitation practices associated with higher rates of in-hospital cardiac arrest survival.Design, setting, and participantsNationwide survey of resuscitation practices at hospitals participating in the Get With the Guidelines-Resuscitation registry and with 20 or more adult in-hospital cardiac arrest cases from January 1, 2012, through December 31, 2013. Data analysis was performed from June 10 to December 22, 2015.Main outcomes and measuresRisk-standardized survival rates for cardiac arrest were calculated at each hospital and were then used to categorize hospitals into quintiles of performance. The association between resuscitation practices and quintiles of survival was evaluated using hierarchical proportional odds logistic regression models.ResultsOverall, 150 (78.1%) of 192 eligible hospitals completed the study survey, and 131 facilities with 20 or more adult in-hospital cardiac arrest cases comprised the final study cohort. Risk-standardized survival rates after in-hospital cardiac arrest varied substantially (median, 23.7%; range, 9.2%-37.5%). Several resuscitation practices were associated with survival on bivariate analysis, although only 3 were significant after multivariable adjustment: monitoring for interruptions in chest compressions (adjusted odds ratio [OR] for being in a higher survival quintile category, 2.71; 95% CI, 1.24-5.93; P = .01), reviewing cardiac arrest cases monthly (adjusted OR for being in a higher survival quintile category, 8.55; 95% CI, 1.79-40.00) or quarterly (OR, 6.85; 95% CI, 1.49-31.30; P = .03), and adequate resuscitation training (adjusted OR, 3.23; 95% CI, 1.21-8.33; P = .02).Conclusions and relevanceUsing survey information from acute care hospitals participating in a national quality improvement registry, we identified 3 resuscitation strategies associated with higher hospital rates of survival for patients with in-hospital cardiac arrest. These strategies can form the foundation for best practices for resuscitation care at hospitals given the high incidence and variation in survival for in-hospital cardiac arrest.

Project description:Massive pulmonary embolism (PE) frequently leads to cardiac arrest (CA) which carries an extremely high mortality rate. Although available, randomized trials have not shown survival benefits from thrombolytic use. Thrombolytics however have been used successfully during resuscitation in clinical practice in multiple case reports and in retrospective studies. Recent resuscitation guidelines recommend using alteplase for PE related CA; however they do not offer a standardized treatment regimen. The most consistently applied approach is an intravenous bolus of 50?mg tissue plasminogen activator (t-PA) early during cardiopulmonary resuscitation (CPR). There is no consensus on the subsequent dosing. We present a case in which two 50?mg boluses of t-PA were administered 20 minutes apart during CPR due to persistent hemodynamic compromise guided by bedside echocardiogram. The patient had an excellent outcome with normalization of cardiac function and no neurologic sequela. This case demonstrates the benefit of utilizing bedside echocardiography to guide administration of a second bolus of alteplase when there is persistent hemodynamic compromise despite achieving return of spontaneous circulation after the initial bolus, and there is evidence of persistent right ventricle dysfunction. Future trials are warranted to help establish guidelines for thrombolytic use in cardiac arrest to maximize safety and efficacy.

Project description:AimsActual resuscitation guidelines recommend 10 respirations per minute (rpm) for advanced pediatric life support. This respiratory rate (RR) is much lower than what is physiological for children. The aim of this study is to compare changes in ventilation, oxygenation, haemodynamics and return of spontaneous circulation (ROSC) rates with three RR.MethodsAn experimental model of asphyxial cardiac arrest (CA) in 46 piglets (around 9.5 kg) was performed. Resuscitation with three different RR (10, 20 and 30 rpm) was carried out. Haemodynamics and gasometrical data were obtained at 3, 9, 18 and 24 minutes after beginning of resuscitation. Measurements were compared between the three groups.ResultsNo statistical differences were found in ROSC rate between the three RR (37.5%, 46.6% and 60% in the 10, 20 and 30 rpm group respectively P = 0.51). 20 and 30 rpm groups had lower PaCO2 values than 10 rpm group at 3 minutes (58 and 55 mmHg vs 75 mmHg P = 0.08). 30 rpm group had higher PaO2 (61 mmHg) at 3 minutes than 20 and 10 rpm groups (53 and 45 mmHg P = 0.05). No significant differences were found in haemodynamics or tissue perfusion between hyperventilated (PaCO2 <30 mmHg), normoventilated (30-50 mmHg) and hypoventilated (>50 mmHg) animals. PaO2 was significantly higher in hyperventilated (PaO2 153 mmHg) than in normoventilated (79 mmHg) and hypoventilated (47 mmHg) piglets (P<0.001).ConclusionsOur study confirms the hypothesis that higher RR achieves better oxygenation and ventilation without affecting haemodynamics. A higher RR is associated but not significantly with better ROSC rates.
