Cardiopulmonary Resuscitation in Pediatric and Cardiac Intensive Care Units

Effect of empathy nursing combined with SBAR communication system on the negative emotions and nursing quality of children with tracheotomy

BACKGROUND

Situation, Background, Assessment, and Recommendation (SBAR) is a structured method for communicating critical information that requires immediate attention and action.

OBJECTIVE

To study the effects of empathy nursing combined with the SBAR communication system on the negative emotions and nursing quality of children undergoing tracheotomy.

METHODS

This is a clinical observational study. A total of 100 tracheotomy patients who were cared for in the pediatric intensive care unit (subsequent treatment in the tracheotomy clinic or otolaryngology ward) of our hospital from September 2021 to June 2022 were recruited and assigned at a ratio of 1:1 either into a control group (empathic care) or an observation group (empathic care combined with SBAR) using a randomized method. Further, the postoperative anxiety self-rating scale scores, negative emotions, hope index, and nursing quality were compared between the two groups.

RESULTS

After nursing, the psychological resilience scale score of the observation group was higher than that of the control group, whereas the anxiety self-rating scale score was significantly lower than that of the control group (all P< 0.05). Basic and special nursing, knowledge awareness, and safety management of the two groups of patients improved significantly, with higher results in the observation group than in the control group (P< 0.05).

CONCLUSION

Empathy nursing combined with the SBAR communication system considerably improves postoperative negative emotions and enhances the quality of nursing care for patients undergoing tracheotomy.

Prediction of Return of Spontaneous Circulation in a Pediatric Swine Model of Cardiac Arrest Using Low-Resolution Multimodal Physiological Waveforms

Monitoring physiological waveforms, specifically hemodynamic variables (e.g., blood pressure waveforms) and end-tidal CO2 (EtCO2), during pediatric cardiopulmonary resuscitation (CPR) has been demonstrated to improve survival rates and outcomes when compared to standard depth-guided CPR. However, waveform guidance has largely been based on thresholds for single parameters and therefore does not leverage all the information contained in multimodal data. We hypothesize that the combination of multimodal physiological features improves the prediction of the return of spontaneous circulation (ROSC), the clinical indicator of short-term CPR success. We used machine learning algorithms to evaluate features extracted from eight low-resolution (4 samples per minute) physiological waveforms to predict ROSC. The waveforms were acquired from the 2nd to 10th minute of CPR in pediatric swine models of cardiac arrest (N = 89, 8-12 kg). The waveforms were divided into segments with increasing length (both forward and backward) for feature extraction, and machine learning algorithms were trained for ROSC prediction. For the full CPR period (2nd to 10th minute), the area under the receiver operating characteristics curve (AUC) was 0.93 (95% CI: 0.87-0.99) for the multivariate model, 0.70 (0.55-0.85) for EtCO2 and 0.80 (0.67-0.93) for coronary perfusion pressure. The best prediction performances were achieved when the period from the 6th to the 10th minute was included. Poor predictions were observed for some individual waveforms, e.g., right atrial pressure. In conclusion, multimodal waveform features carry relevant information for ROSC prediction. Using multimodal waveform features in CPR guidance has the potential to improve resuscitation success and reduce mortality.

Does Compliance with Resuscitation Practice Guidelines Differ Between Pediatric Intensive Care Units and Cardiac Intensive Care Units?

Objective: Hospitalized children with cardiac disease have the highest rate of cardiac arrest compared to other disease types. Different intensive care unit (ICU) models exist, but it remains unknown whether resuscitation guideline adherence is different between cardiac ICUs (CICU) and general pediatric ICUs (PICU). We hypothesize there is no difference in resuscitation practices between unit types. Design: Retrospective observational study. Setting: The American Heart Association's Get With The Guidelines®-Resuscitation (GWTG-R) registry. Patients: Children < 18 years old with medical or surgical cardiac disease who had cardiopulmonary arrest from 2014 to 2018. Intervention: None. Measurements and Main Results: Events were assessed for compliance with GWTG-R achievement measures of time to first chest compressions ≤ 1 min, time to intravenous/intraosseous epinephrine ≤ 5 min, time to first shock ≤ 2 min for ventricular fibrillation (VF)/pulseless ventricular tachycardia (VT), and confirmation of endotracheal tube placement. Additional practices were evaluated for consistency with Pediatric Advanced Life Support (PALS) recommendations. Eight hundred and eighty-six patients were evaluated, 687 (79%) in CICUs and 179 (21%) in PICUs. 484 (56%) had surgical cardiac disease. There were no differences in GWTG-R achievement measures or PALS recommendations between ICU types in univariable or multivariable models. Amiodarone, lidocaine, and nonstandard medication use did not differ by unit type. Extracorporeal cardiopulmonary resuscitation (ECPR) was more common in CICUs for both medical (16% vs 7%) and surgical (25% vs 2.5%) categories (P < .0001). Conclusions: Resuscitation compliance for patients with cardiac disease is similar between CICUs and PICUs. Patients were more likely to receive ECPR in CICUs. Additional study should evaluate how ICU type affects arrest outcomes in children with cardiac disease.

Evaluation of Pediatric Cardiac Intensive Care Advanced Practice Provider's Leadership Education and Experience During Emergencies

BACKGROUND

The number of advanced practice providers (APPs) in pediatric critical care has increased dramatically over recent years, leading to increased opportunities to lead resuscitation teams during pediatric emergent events.

OBJECTIVES

The aim of this study was to better understand the emergency leadership experience, training, and education that pediatric cardiac intensive care unit APPs receive.

METHODS

This study was a cross-sectional descriptive studying using survey responses. The self-administered survey was administered to APP and attending physician members of the Pediatric Cardiac Intensive Care Society. Survey results were analyzed.

RESULTS

One hundred seven pediatric cardiac intensive care unit APPs (n = 53) and attending physicians (n = 54) responded to the survey. Half of APPs felt that attendings allowed APPs to lead emergent events, and 50.9% had never functioned in the team leader role. Most respondents (77.5%) rated their comfort functioning in the role during emergent situations as moderate or lower. Increased APP experience level was associated with a higher number of codes led, increased comfort leading codes, and improved mental model sharing (all Ps < .0001). The number of codes an APP had previously led was associated with increased comfort leading codes (P < .0001) and mental model sharing (P = .0002). One-third of attendings said they allow APPs to lead codes in their unit. Half of attendings who do not allow APPs to function as the team leader would follow formal training.

DISCUSSION

Opportunities for APPs to function as team leaders during emergent events continue to increase. A leadership educational program would be beneficial to pediatric critical care APPs. It may also have the additional benefit of improving physician comfort with APPs leading code events and patient outcomes.

Five vs. two initial rescue breaths during infant basic life support: A manikin study using bag-mask-ventilation

BACKGROUND AND OBJECTIVES

Children are more likely to suffer a hypoxic-ischaemic cause for cardiac arrest. Early ventilation may provide an advantage in outcome during paediatric cardiopulmonary resuscitation [CPR]. European Resuscitation Council guidelines recommend five initial rescue breaths [IRB] in infants, stemming from the hypothesis that rescuers might need 5 attempts in order to deliver 2 effective ventilations. This study aimed to verify this hypothesis.

METHODS

Participants (n = 112, convenience sample) were medical students from the Faculty of Medicine and Health Sciences Ghent University, Belgium. Students were divided into duos and received a 15 min just-in-time training regarding the full CPR-cycle using BMV. Participants then performed five cycles of 2-person CPR. The IRB were given by 1-person BMV, as opposed to a 2-persons technique during the further CPR-cycle. Correct ventilations for the infant were defined as tidal volumes measured (Laerdal® Q-CPR) between 20 and 60 ml, with n = 94 participants included in the analysis. The primary outcome consisted of the difference in the % of medical student duos providing at least 2 effective IRB between 2 and 5 attempts.

RESULTS

Off all duos, 55,3% provided correct volumes during their first 2 initial ventilations. An increase up to 72,4% was noticed when allowing 5 ventilations. The proportional difference between 2 and 5 IRB allowed was thus significant [17,0%, 95% confidence interval (5.4; 28.0)].

CONCLUSION

In this manikin study, 5 IRB attempts during infant CPR with BMV increased the success rate in delivering 2 effective ventilations. Besides, students received training emphasizing the need for 5 initial rescue breaths. This study provides evidence supporting European Resuscitation Council guidelines.

Influence of Cardiopulmonary Resuscitation Coaching on Interruptions in Chest Compressions During Simulated Pediatric Cardiac Arrest

OBJECTIVES

To determine the impact of a cardiopulmonary resuscitation coach on the frequency and duration of pauses during simulated pediatric cardiac arrest.

DESIGN

This is a secondary analysis of video data collected from a prospective multicenter trial. Forty simulated pediatric cardiac arrest scenarios (20 noncoach and 20 coach teams), each lasting 18 minutes in duration, were reviewed by three clinical experts to document events surrounding each pause in chest compressions.

SETTING

Four pediatric academic medical centers from Canada and the United States.

SUBJECTS

Two-hundred healthcare providers in five-member interprofessional resuscitation teams that included either a cardiopulmonary resuscitation coach or a noncoach clinical provider.

INTERVENTIONS

Teams were randomized to include either a trained cardiopulmonary resuscitation coach or an additional noncoach clinical provider.

MEASUREMENTS AND MAIN RESULTS

The frequency, duration, and associated factors with each interruption in chest compressions were recorded and compared between the groups with and without a cardiopulmonary resuscitation coach, using t tests, Wilcoxon rank-sum tests, or chi-squared tests, depending on the distribution and types of outcome variables. Mixed-effect linear models were used to explore the effect of cardiopulmonary resuscitation coaching on pause durations, accounting for multiple measures of pause duration within teams. A total of 655 pauses were identified (noncoach n = 304 and coach n = 351). Cardiopulmonary resuscitation-coached teams had decreased total mean pause duration (98.6 vs 120.85 s, p = 0.04), decreased intubation pause duration (median 4.0 vs 15.5 s, p = 0.002), and similar mean frequency of pauses (17.6 vs 15.2, p = 0.33) when compared with noncoach teams. Teams with cardiopulmonary resuscitation coaches are more likely to verbalize the need for pause (86.5% vs 73.7%, p < 0.001) and coordinate change of the compressors, rhythm check, and pulse check (31.7% vs 23.2%, p = 0.05). Teams with cardiopulmonary resuscitation coach have a shorter pause duration than non-coach teams, adjusting for number and types of tasks performed during the pause.

CONCLUSIONS

When compared with teams without a cardiopulmonary resuscitation coach, the inclusion of a trained cardiopulmonary resuscitation coach leads to improved verbalization before pauses, decreased pause duration, shorter pauses during intubation, and better coordination of key tasks during chest compression pauses.

Non-invasive diffuse optical neuromonitoring during cardiopulmonary resuscitation predicts return of spontaneous circulation

Neurologic injury is a leading cause of morbidity and mortality following pediatric cardiac arrest. In this study, we assess the feasibility of quantitative, non-invasive, frequency-domain diffuse optical spectroscopy (FD-DOS) neuromonitoring during cardiopulmonary resuscitation (CPR), and its predictive utility for return of spontaneous circulation (ROSC) in an established pediatric swine model of cardiac arrest. Cerebral tissue optical properties, oxy- and deoxy-hemoglobin concentration ([HbO₂], [Hb]), oxygen saturation (StO₂) and total hemoglobin concentration (THC) were measured by a FD-DOS probe placed on the forehead in 1-month-old swine (8–11 kg; n = 52) during seven minutes of asphyxiation followed by twenty minutes of CPR. ROSC prediction and time-dependent performance of prediction throughout early CPR (< 10 min), were assessed by the weighted Youden index (J_w, w = 0.1) with tenfold cross-validation. FD-DOS CPR data was successfully acquired in 48/52 animals; 37/48 achieved ROSC. Changes in scattering coefficient (785 nm), [HbO₂], StO₂ and THC from baseline were significantly different in ROSC versus No-ROSC subjects (p < 0.01) after 10 min of CPR. Change in [HbO₂] of + 1.3 µmol/L from 1-min of CPR achieved the highest weighted Youden index (0.96) for ROSC prediction. We demonstrate feasibility of quantitative, non-invasive FD-DOS neuromonitoring, and stable, specific, early ROSC prediction from the third minute of CPR.

Use of Sodium Bicarbonate During Pediatric Cardiac Admissions with Cardiac Arrest: Who Gets It and What Does It Do?

The objectives of this study were to characterize the use of sodium bicarbonate in pediatric cardiac admissions that experience cardiac arrest, to determine sodium bicarbonate use over the years, and to determine the impact of sodium bicarbonate on length of admissions, billed charges, and inpatient mortality. A cross-sectional study was conducted utilizing the Pediatric Health Information System database. Characteristics of admissions with and without sodium bicarbonate were initially compared by univariate analyses. The frequency by which sodium bicarbonate was used was compared by year. Regression analyses were conducted to determine the impact of sodium bicarbonate on length of stay, billed charges, and inpatient mortality. A total of 3987 (50.3%) of pediatric cardiac intensive care admissions with cardiac arrest utilized sodium bicarbonate; however, frequency changed from 62.1% in 2004 to 43.7% in 2015. Linear regression analysis demonstrated a decrease in length of stay (-27.5 days, p < 0.01) and billed charges (-$470,906, p < 0.01). Logistic regression analysis demonstrated an increase in mortality (odds ratio 1.77, 95% confidence interval 1.56-2.01). In conclusion, sodium bicarbonate is being used with less frequency over the last years in pediatric cardiac admissions with cardiac arrest. After adjustment for cardiac diagnoses, comorbidities, vasoactive medications, and other resuscitation medications, sodium bicarbonate is independently associated with increased mortality.

Pediatric Pharmacists' Participation in Cardiopulmonary Resuscitation Events

The Pediatric Pharmacy Advocacy Group (PPAG) understands the dilemma and varying factors that many institutions face concerning the routine participation of pharmacists in emergency resuscitation events. Acknowledging these obstacles, the PPAG encourages all institutions to strongly consider creating, adopting, and upholding policies to address pharmacists' participation in cardiopulmonary resuscitation (CPR) as evidenced by the impact pharmacist participation has shown on the reduction of hospital medication error and mortality rates in children. The PPAG advocates that pharmacists be actively involved in the institution's CPR, medical emergency team committees, and preparation of emergency drug kits and resuscitation trays. The PPAG advocates that all institutions requiring a pharmacist's participation in CPR events consider adoption of preparatory training programs. Although the PPAG does not advocate any one specific program, consideration should be taken to ensure that pharmacists are educated on the pharmacotherapy of drugs used in the CPR process, including but not limited to basic life support, Advanced Cardiac Life Support, and Pediatric Advanced Life Support algorithms; medication preparation and administration guidelines; medication compatibility; recommended dosing for emergency medications; and familiarity with the institutional emergency cart.
