Abstract Su607: Which would be major? witnessed collapse or bystander resuscitation?

Background: Witnessed collapse and bystander cardiopulmonary resuscitation (CPR) are two variables commonly used to predict outcomes in out-of-hospital cardiac arrest (OHCA). Some published studies have shown that bystander CPR were not significantly associated with outcomes after confounders adjusted. This may imply that witnessed collapse would be a superior prognostic factors beyond bystander CPR. Hypothesis: Witnessed collapse and bystander CPR may not contribute equally to prehospital return of spontaneous circulation (ROSC), and the former may be major. Aims: To investigate four prediction models for prehospital ROSC using stratification of the witnessed collapse and bystander CPR. Methods: The study enrolled OHCA patients treated by the emergency medical service (EMS) from January 2010 to December 2022 in three EMS systems in Taiwan. Data were extracted from the records of each medical service encounter, including patient demographics, dispatch timing, prehospital management, witnessed collapse and bystander CPR. The primary outcome was any prehospital ROSC. Patients were stratified into four groups by witnessed collapse (with/without) and bystander CPR (with/without) status, namely W+B+, W-B+, W+B- and W-B-. Prehospital ROSC prognostication were identified using multivariable logistic regression analysis. Results: The analysis comprised 17,323 patients, among whom 1,165 (6.7%) achieved prehospital ROSC. The W+B+ group demonstrated the highest prehospital ROSC rate at 13.0%, as compared with the other groups significantly (9.0%, 3.4%, and 4.1%, as depicted in Image 1). Stratification of the prehospital ROSC model (Image 2) indicated that the W+B+ group had several common predictors including age, traumatic arrest, no-flow time, public access defibrillation (PAD), and resuscitation events. However, certain predictors in other groups were removed during regression process. Notably, no-flow time significantly influenced prehospital ROSC only in the W+B+ and W+B- groups. Conversely, in the W-B- group, most variables had minimal impact on prehospital ROSC, reflecting the limited effectiveness of traditional predictors within this subgroup. Conclusion: The significance of witnessed collapse as a prognostic factor may be equal to or even greater than that of bystander CPR. Further studies are needed to confirm.

In vivo evaluation of an adaptive resuscitation controller using whole blood and crystalloid infusates for hemorrhagic shock

IntroductionHemorrhage remains the leading cause of preventable death on the battlefield. The most effective means to increase survivability is early hemorrhage control and fluid resuscitation. Unfortunately, fluid resuscitation requires constant adjustments to ensure casualty is properly managed, which is often not feasible in the pre-hospital setting. In this study, we showed how an adaptive closed-loop controller for hemorrhage resuscitation can be used to automate hemodynamic management using a swine hemorrhagic shock injury model.MethodsThe adaptive resuscitation controller (ARC) was previously developed to track pressure–volume responsiveness in real time and adjust its infusion rate to reach the target mean arterial pressure (MAP). Swine while maintained under a surgical plane of anesthesia and analgesia underwent a splenectomy, followed by two hemorrhage and resuscitation events. For the first resuscitation event, hemorrhage was induced to reduce the MAP to 35 mmHg until arterial lactate reached 4 mmol/L. The ARC system then infused whole blood (WB) to reach the target MAP and maintained the subject using crystalloids for 120 min. For the second resuscitation event, the subjects were hemorrhaged again but resuscitated using only crystalloid infusion to reach the target MAP and 120-min maintenance.ResultsThe ARC was effective at WB resuscitation, reaching the target MAP in 2.0 ± 1.0 min. The median performance error was 1.1% ± 4.6%, and target overshoot was 14.4% ± 7.0% of the target MAP. The ARC maintained all animals throughout the 120 min maintenance period. For the second crystalloid-based resuscitation, ARC required a longer time to reach the target MAP, at an average rise time of 4.3 ± 4.0 min. However, target overshoot was reduced to 8.4% ± 7.3% of the target MAP. Much higher flow rates were required to maintain the target MAP during the second resuscitation event than during the first resuscitation event.DiscussionThe ARC was able to rapidly reach and maintain the target MAP effectively. However, this sometimes required large volumes of fluid as the ARC’s only goal was to reach the target MAP. Further clinical insight is needed regarding the preferred aggression level to achieve the target MAP. In conclusion, the ARC was successful in its programmed objective of reaching and maintaining the target MAP for extended periods of time in vivo, a critical next step toward improving hemorrhage treatment in the pre-hospital environment.

Evaluation of propofol-based procedural sedation in pediatric hemato-oncological patients provided by physician assistants in anesthesia.

Procedural sedation and analgesia are required for painful hemato-oncological procedures such as lumbar and bone marrow punctures. At our institution, sedation with propofol and alfentanil is usually provided by Physician Assistants in Anesthesia. We evaluated the adverse events during the PSA program for children, provided by Physician Assistants in Anesthesia. We included pediatric patients meeting our criteria for deep sedation by a Physician Assistants in Anesthesia, scheduled for a hemato-oncological procedure at the Amalia Children's Hospital at the Radboudumc Nijmegen. The primary outcome was oxygen desaturation below 92% for more than 20 s. We prospectively collected data on demographics, current health problems, type of procedure, need for airway interventions, and hypotension. We collected data from 437 sedation sessions involving 71 patients. No oxygen desaturation below 92% lasting longer than 20 s occurred. In 2 cases, a jaw thrust was performed. No invasive airway techniques (oropharyngeal cannula, laryngeal mask, or intubation) were required. A significant drop in mean arterial pressure was seen in 2 out of 437 cases (0.5%). There was no occurrence of cardiopulmonary resuscitation or other adverse events such as aspiration or laryngeal spasm. Sedation and analgesia for short painful procedures in selected pediatric hemato-oncological units with a dedicated protocol may be safely provided by trained and certified Physician Assistants in Anesthesia.

Enhancing Team Dynamics and Leadership Skills for Residents Leading Multidisciplinary In-Patient Cardiac Arrest Teams

Background: Cardiac arrest is a prevalent event with low survival rates, both in out-of-hospital and in-hospital settings. There is a lack of specific training programs addressing team dynamics and leadership skills during resuscitation events, creating a clinical gap. This project aimed to enhance team dynamics and improve leadership skills during IHCA resuscitation events. Methods: We implemented the Mock Code Project for resident physicians from our Internal Medicine Residency Programs in the simulation center (i.e., in a controlled environment) to address this gap. Multidisciplinary team mock code scenarios were created for residents, allowing them to lead resuscitation simulations. The scenarios were based upon common conditions encountered during codes (Cardiac arrest). Trained evaluators provided real-time feedback, and pre-and post-surveys were conducted to assess team perception and gather feedback. Results: Baseline data revealed that 98.6% (143 of 145 residents total) felt uncertain or lacked confidence in leading effective codes in our hospital prior to the intervention. Post-test survey outcome data revealed that 95.1% of participants (136 residents of 143) reported that the sessions challenged their skills at leading codes and improved their skills at managing resuscitation teams. Conclusion: Organized codes with clear roles, responsibilities, bed positioning, and clear leadership significantly improve closed-loop communication, effective team interaction, and patient outcomes. The Mock Code Project fills the gap in training programs by focusing on team dynamics and leadership skills during IHCA resuscitation. Ongoing evaluations and feedback ensure continual improvement in resident confidence and skills. Implementing organized codes benefits residents and healthcare teams, ultimately improving patient care during IHCA. Well-designed mock code scenarios with real-time feedback from senior physicians are an effective way for trainees to develop these skills and this awareness without compromising patient safety.

Does the Use of an Automated Resuscitation Recorder Improve Adherence to NRP Algorithms and Code Documentation?

Neonatal resuscitation is guided by Neonatal Resuscitation Program (NRP) algorithms; however, human factors affect resuscitation. Video recordings demonstrate that deviations are common. Additionally, code documentation is prone to inaccuracies. Our long-term hypothesis is that the use of an automated resuscitation recorder (ARR) app will improve adherence to NRP and code documentation; the purpose of this study was to determine its feasibility. We performed a simulation-based feasibility study using simulated code events mimicking NRP scenarios. Teams used the app during resuscitation events. We collected data via an initial demographics survey, video recording, ARR-generated code summary and a post-resuscitation survey. We utilized standardized grading tools to assess NRP adherence and the accuracy of code documentation through resuscitation data point (RDP) scoring. We evaluated provider comfort with the ARR via post-resuscitation survey ordinal ratings and open-ended question text mining. Summary statistics for each grading tool were computed. For NRP adherence, the median was 68% (range 60-76%). For code documentation accuracy and completeness, the median was 77.5% (range 55-90%). When ordinal ratings assessing provider comfort with the app were reviewed, 47% chose "agree" (237/500) and 36% chose "strongly agree" (180/500), with only 0.6% (3/500) answering "strongly disagree". A word cloud compared frequencies of words from the open-ended text question. We demonstrated the feasibility of ARR use during neonatal resuscitation. The median scores for each grading tool were consistent with passing scores. Post-resuscitation survey data showed that participants felt comfortable with the ARR while highlighting areas for improvement. A pilot study comparing ARR with standard of care is the next step.

Association between pre-arrest left ventricular ejection fraction and survival in nontraumatic out-of-hospital cardiac arrest.

Out-of-hospital cardiac arrest (OHCA) poses major public health issues. Pre-arrest heart function is a prognostic factor, but the specific contribution of pre-arrest echocardiographic evaluation in predicting OHCA outcome remains limited. The primary objective was to investigate the association between left ventricular ejection fraction (LVEF) measured in echocardiography prior to OHCA and survival to hospital discharge. This multicenter retrospective cohort study analyzed data from the National Taiwan University Hospital and its affiliated hospitals. We included adult nontraumatic OHCA patients who were treated by the emergency medical services (EMS) and underwent echocardiography within 6 months prior to the OHCA event from January 2016 to December 2022. Data included demographics, preexisting diseases, resuscitation events, and echocardiographic reports. The primary outcome was the survival to hospital discharge after post-arrest care. Statistical analysis involved multivariable logistic regression to modify potential confounders, reported as adjusted odds ratio (aOR) and 95% confidence interval (CI), and evaluate the association between echocardiographic findings and survival to hospital discharge. This study analyzed 950 patients, with 33.6% surviving to discharge. A higher pre-arrest LVEF was independently associated with increased survival. Compared to patients with LVEF < 40%, those with LVEF between 40% and 60% had significantly higher odds of survival (aOR = 3.68, 95% CI = 2.14-6.35, P < 0.001), and those with LVEF > 60% had even greater odds of survival (aOR = 5.46, 95% CI = 3.09-9.66, P < 0.001). There was also an association between lower tricuspid regurgitation pressure gradient and survival (aOR = 0.98, 95% CI = 0.97-1.00, P = 0.015). Younger age, male gender, dyslipidemia, stroke, cancer, witnessed arrest, initial shockable rhythm, and shorter low-flow time are other significant predictors of survival. In adult, nontraumatic, EMS-treated OHCA patients, a higher LVEF 6 months prior to OHCA was associated with improved survival at hospital discharge.

Detection of time of birth and cord clamping using thermal video in the delivery room.

Newborn resuscitation algorithms emphasize that resuscitation is time-critical, and all algorithm steps are related to the time of birth. Infrared thermal video has the potential to capture events in the delivery room, such as birth, cord clamping, and resuscitative interventions, while upholding the privacy of patients and healthcare providers. The objectives of this concept study were to (i) investigate the technical feasibility of using thermal video in the delivery room to detect birth and cord clamping, and (ii) evaluate the accuracy of manual real-time registrations of the time of birth and cord clamping by comparing it with the accuracy of registrations abstracted from thermal videos. An observational study with data collected at Stavanger University Hospital, Norway, from September 2022 to August 2023. The time of birth and cord clamping were manually registered on a portable tablet by healthcare providers. Thermal cameras were placed in the delivery rooms and operating theatre to capture births. Videos were retrospectively reviewed to determine the time of birth and cord clamping. Participation consent was obtained from 306 mothers, of which 195 births occurred in delivery rooms or an operating theatre with a thermal camera installed. We excluded 12 videos in which no births occurred. Births were detectable in all 183 (100%) thermal videos evaluated. There was a median (quartiles) of 1.8 (0.7, 5.4) s deviation in the manual registrations of the times of births relative to those abstracted from thermal videos. Cord clamping was detectable in 173 of the 183 (95%) thermal videos, with a median of 18.3 (3.3, 108) s deviation in the manual registrations of the times of cord clampings relative to those abstracted from thermal videos. Recognizing the time of birth and cord clamping from thermal videos is technically feasible and provides a method for determining when resuscitative events occur.

Exploring the genuine psychological experiences of novice nurses at emergency resuscitation events: A qualitative interview study

PurposeAn emergency rescue situation is an inevitable challenge in medical work, requiring collaborative efforts from healthcare professionals. Due to a lack of practical experience, novice nurses may encounter difficulties in successfully managing emergency resuscitation events. This study aimed to analyse the authentic psychological experiences of novice nurses participating in emergency resuscitation events by exploring applicable coping methods and management strategies. MethodsThis study utilized a hermeneutic phenomenological qualitative research method. We employed purposive sampling to select 27 Novice nurses from West China Hospital of Sichuan University for face-to-face semistructured interviews. Data collection for this study was conducted from November 2023 to January 2024. The interviews were fully audio-recorded and transcribed verbatim. The data were coded, categorized and summarized with the help of Nvivo 20.0 software based on the interpretation of phenomenological research methods. Thematic analysis was performed to deeply analyse and extract corresponding themes. The COREQ criteria were used to guide the reporting of this study. ResultsThe authentic psychological experiences of novice nurses participating in emergency rescue events mainly include six aspects: lack of rescue knowledge reserves and related abilities, psychological and emotional changes, psychological stress after the rescue, rational arrangement of manpower, team cooperation, and postevent reflection and learning. Their authentic psychological experiences directly affect whether novice nurses can effectively respond to emergency rescue events. ConclusionsThis study suggested enhancing novice nurses' knowledge, improving their resuscitation skills, and improving their psychological well-being during resuscitation events. It advocates for organized staffing, effective teamwork, and robust support systems to empower novice nurses and improve their overall capabilities in emergencies. These findings offer valuable insights for future research in this area.

Comparison of Blalock-Taussig-Thomas Shunts With Patent Ductus Arteriosus Ligated Versus Left Open.

The optimal approach to patent ductus arteriosus management during systemic-to-pulmonary artery shunt placement is currently unknown. The purpose of this study is to examine the outcomes of variable strategies for patent ductus arteriosus management during Blalock-Taussig-Thomas shunt surgery. A retrospective cohort study of infants who underwent shunt placement was performed, comparing those who had the ductus ligated with those who had the ductus left open. Indicators of low cardiac output syndrome, development of necrotizing enterocolitis, and secondary outcomes such as resuscitation events were examined. Thirty-six infants were included all of whom had their shunt placed via median sternotomy. Twenty infants had their ductus ligated at the time of the shunt, and they were compared with 16 infants whose ductus was left open. There was no statistical difference in preoperative baseline characteristics, including corrected gestational age, age in days, weight, mechanical ventilation, vasoactive use, heterotaxy, and gastrointestinal anomalies. There was also no statistical difference in postoperative indicators of low cardiac output, including urine production, total fluids given, renal injury, maximum lactate, and vasoactive-inotropic score. Three patients had postoperative renal injury, and all were in the ligated duct group. There was also no statistical difference in any secondary outcomes, including the development of necrotizing eneterocolitis, resuscitation events, reinterventions, length of intubation, total length of stay, and mortality. This study provides evidence that variable management of the ductus during shunt placement does not significantly impact outcomes. Leaving the ductus open allows for a potential rescue source of pulmonary blood flow and does not appear to increase the risk of postoperative low cardiac output.

Early bolus epinephrine administration during pediatric cardiopulmonary resuscitation for bradycardia with poor perfusion: an ICU-resuscitation study

BackgroundHalf of pediatric in-hospital cardiopulmonary resuscitation (CPR) events have an initial rhythm of non-pulseless bradycardia with poor perfusion. Our study objectives were to leverage granular data from the ICU-RESUScitation (ICU-RESUS) trial to: (1) determine the association of early epinephrine administration with survival outcomes in children receiving CPR for bradycardia with poor perfusion; and (2) describe the incidence and time course of the development of pulselessness.MethodsPrespecified secondary analysis of ICU-RESUS, a multicenter cluster randomized trial of children (< 19 years) receiving CPR in 18 intensive care units in the United States. Index events (October 2016–March 2021) lasting ≥ 2 min with a documented initial rhythm of bradycardia with poor perfusion were included. Associations between early epinephrine (first 2 min of CPR) and outcomes were evaluated with Poisson multivariable regression controlling for a priori pre-arrest characteristics. Among patients with arterial lines, intra-arrest blood pressure waveforms were reviewed to determine presence of a pulse during CPR interruptions. The temporal nature of progression to pulselessness was described and outcomes were compared between patients according to subsequent pulselessness status.ResultsOf 452 eligible subjects, 322 (71%) received early epinephrine. The early epinephrine group had higher pre-arrest severity of illness and vasoactive-inotrope scores. Early epinephrine was not associated with survival to discharge (aRR 0.97, 95%CI 0.82, 1.14) or survival with favorable neurologic outcome (aRR 0.99, 95%CI 0.82, 1.18). Among 186 patients with invasive blood pressure waveforms, 118 (63%) had at least 1 period of pulselessness during the first 10 min of CPR; 86 (46%) by 2 min and 100 (54%) by 3 min. Sustained return of spontaneous circulation was highest after bradycardia with poor perfusion (84%) compared to bradycardia with poor perfusion progressing to pulselessness (43%) and bradycardia with poor perfusion progressing to pulselessness followed by return to bradycardia with poor perfusion (62%) (p < 0.001).ConclusionsIn this cohort of pediatric CPR events with an initial rhythm of bradycardia with poor perfusion, we failed to identify an association between early bolus epinephrine and outcomes when controlling for illness severity. Most children receiving CPR for bradycardia with poor perfusion developed subsequent pulselessness, 46% within 2 min of CPR onset.

Improving Neonatal Resuscitation Knowledge in Advanced Providers Through Simulation: A Quality Improvement Project.

Advanced neonatal resuscitation events are high-risk, low-volume critical situations. Healthcare systems have placed emphasis on improving resuscitation skills for advanced providers based on evidence showing that it can directly impact patient outcomes. Neonatal resuscitation program (NRP) renewal is only required every 2 years. This gap and low usage of skills can result in lack of competency and expertise leading to an increased risk of poor patient outcomes. This project aimed to provide simulation education based on NRP curriculum for a large group of advanced providers at multiple level II, III, and IV neonatal intensive care units (NICUs) and to improve confidence and knowledge in advanced resuscitation. A high-fidelity mannequin was used to simulate a reproducible, critical scenario that spanned the entire NRP algorithm. NRP knowledge and the effectiveness of simulation on confidence and knowledge in neonatal resuscitation were measured. The average knowledge score from the pretest to the posttest improved by 7%. Based on the simulation evaluation tool-modified (SET-M), debriefing was the most effective in improving confidence and knowledge. The neonatal nurse practitioners (NNPs) with the most years of clinical experience had the largest improvement in knowledge. With the most experienced NNPs providing majority of coverage in the Level II NICUs, a correlation may be drawn that the effect of simulations on NRP knowledge has a greater impact on these groups due to the low exposure of advanced resuscitation events at these sites. Debriefing stood out as the most critical component of simulation.

Comparison of shelf-stable and conventional resuscitation products in a canine model of hemorrhagic shock.

Treatment of severe hemorrhagic shock typically involves hemostatic resuscitation with blood products. However, logistical constraints often hamper the wide distribution of commonly used blood products like whole blood. Shelf-stable blood products and blood substitutes are poised to be able to effectively resuscitate individuals in hemorrhagic shock when more conventional blood products are not readily available. Purpose-bred adult dogs (n = 6) were anesthetized, instrumented, and subjected to hemorrhagic shock (mean arterial pressure <50 mm Hg or 40% blood volume loss). Then each dog was resuscitated with one of five resuscitation products: (1) lactated ringers solution and hetastarch (LRS/Heta), (2) canine chilled whole blood (CWB), (3) fresh frozen plasma (FFP) and packed red blood cells (pRBC), (4) canine freeze-dried plasma (FDP) and hemoglobin-based oxygen carrier (HBOC), or (5) HBOC/FDP and canine lyophilized platelets (LyoPLT). Each dog was allowed to recover after the hemorrhage resuscitation event and was then subjected to another hemorrhage event and resuscitated with a different product until each dog was resuscitated with each product. At the time when animals were determined to be out of shock as defined by a shock index <1, mean arterial pressure (mmHg) values (mean ± standard error) were higher for FFP/pRBC (n = 5, 83.7 ± 4.5) and FDP/HBOC+LyoPLT (n = 4, 87.8 ± 2.1) as compared with WB (n = 4, 66.0 ± 13.1). A transient increase in creatinine was seen in dogs resuscitated with HBOC and FDP. Albumin and base excess increased in dogs resuscitated with HBOC and FDP products compared with LRS/heta and CWB ( p < 0.01). Combinations of shelf-stable blood products compared favorably to canine CWB for resolution of shock. Further research is needed to ascertain the reliability and efficacy of these shelf-stable combinations of products in other models of hemorrhage that include a component of tissue damage as well as naturally occurring trauma.

Post-resuscitation talk in the intensive care unit : Living interprofessionalism-amust have!

In the context of medical care, healthcare professionals are confronted with cardiopulmonary resuscitation, which can have long-term effects on the participants. The aim was to develop, implement, and evaluate aprotocol-supported post-resuscitation talk for practice in the intensive care unit of auniversity hospital. Within the evidence-based nursing working group, university-qualified nurses performed asystematic literature search in CareLit (hpsmedia, Hungen, Germany), the Cochrane Library (Cochrane, London, England), LIVIVO (Deutsche Zentralbibliothek für Medizin, Cologne, Germany), and PubMed/MEDLINE (U.S. National Library of Medicine, Bethesda, MD, USA) as well as using the snowball principle. Based on the results, the post-resuscitation talk and adebriefing protocol were developed and consented in amultiprofessional team. Additionally, aquestionnaire to analyze the current situation (t0) and evaluate the implementation (t1) was developed. Implementation of the post-resuscitation talk was conducted from August 2021. The t0 survey took place from June to July 2021 and for t1 from February to March 2022. In t0, fewer interprofessional reflections were carried out after resuscitations in the category always or frequently (17.5%, n = 7) than in t1 (50.0%, n = 13). The rate of initiated improvement interventions was increased (t0: 24.3%, n = 9 vs. t1: 59.1%, n = 13). The results show promotion of multiprofessional collaboration in t0 and t1, and potential for optimization in the debriefing protocol in t1. Implementation of apost-resuscitation talk in hospitals is auseful tool for the structured interprofessional follow-up of resuscitation events. The results demonstrated initial positive effects and potential for optimization.

Newborn resuscitation timelines: Accurately capturing treatment in the delivery room

ObjectivesTo evaluate the use of newborn resuscitation timelines to assess the incidence, sequence, timing, duration of and response to resuscitative interventions. MethodsA population–based observational study conducted June 2019–November 2021 at Stavanger University Hospital, Norway. Parents consented to participation antenatally. Newborns ≥28 weeks’ gestation receiving positive pressure ventilation (PPV) at birth were enrolled. Time of birth was registered. Dry-electrode electrocardiogram was applied as soon as possible after birth and used to measure heart rate continuously during resuscitation. Newborn resuscitation timelines were generated from analysis of video recordings. ResultsOf 7466 newborns ≥28 weeks’ gestation, 289 (3.9%) received PPV. Of these, 182 had the resuscitation captured on video, and were included. Two-thirds were apnoeic, and one-third were breathing ineffectively at the commencement of PPV. PPV was started at median (quartiles) 72 (44, 141) seconds after birth and continued for 135 (68, 236) seconds. The ventilation fraction, defined as the proportion of time from first to last inflation during which PPV was provided, was 85%. Interruption in ventilation was most frequently caused by mask repositioning and auscultation. Suctioning was performed in 35% of newborns, in 95% of cases after the initiation of PPV. PPV was commenced within 60 s of birth in 49% of apnoeic and 12% of ineffectively breathing newborns, respectively. ConclusionsNewborn resuscitation timelines can graphically present accurate, time-sensitive and complex data from resuscitations synchronised in time. Timelines can be used to enhance understanding of resuscitation events in data-guided quality improvement initiatives.

Impact of video recordings review with structured debriefings on trauma team performance: a prospective observational cohort study.

To determine the impact of structured debriefings (SD) with audio/video review of trauma patients' resuscitation events on trauma team (TT) technical and non-technical skills. Single-center prospective observational cohort study. The study included all emergency department patients aged 18years or older who received resuscitation from the TT. Virtual meeting was held with the TT using SD to review one trauma patient resuscitation video. Technical skills improvement was based on adherence to the ATLS protocol and non-technical skills based on T-NOTECHS scale. There was statistically significant improvement in adherence to the ATLS protocol: 73% [55-82%] vs 91% [82-100%] (p < 0.001); and improvement in T-NOTECHS scale: 12 [10-14] vs 16 [14-19] points (p < 0.001). In this study, we found that structured debriefings with review of patients' resuscitation video recordings can have a significant positive impact on trauma team performance in the emergency department in both technical and non-technical skills.

Effectiveness of Alprostadil for Ductal Patency

OBJECTIVES This study aims to describe the effectiveness of low initial alprostadil dosages to maintain a patent ductus arteriosus (PDA) in infants with ductal-dependent congenital heart disease (DDCHD). Secondary objectives were to describe any adverse drug events, describe prescribing trends, describe ductus arteriosus diameter changes, and compare the safety and efficacy of very low and low initial alprostadil dosage regimens. METHODS This retrospective observational cohort study at the British Columbia’s Women’s and Children’s Hospital neonatal intensive care unit and pediatric intensive care unit examined neonates admitted with DDCHD who received alprostadil to maintain ductal patency. Very low–dose alprostadil (less than 0.01 mcg/kg/min) versus low-dose alprostadil (equal to or greater than 0.01 mcg/kg/min) was examined. Effectiveness was defined as survival and infants not requiring a resuscitation event (cardiac arrest, cardiogenic shock, code blue, extracorporeal life support, requirement for emergent cardiac surgery, and respiratory acidosis). Adverse drug events with a Naranjo score of 3 or more were included. RESULTS Alprostadil was effective for 88% of patients, with no difference between the very low–dose and low-dose groups. Of the 75 patients included, 25 received very low–dose alprostadil. Adverse drug events were common (51%) with neonates in the low-dose group experiencing more apnea and pyrexia than neonates in the very low–dose group. CONCLUSIONS Alprostadil therapy was effective in maintaining the PDA in neonates with DDCHD with low-dosage regimens. Adverse drug events were common with both dosage regimens; however, the very low dosage appeared to have less apnea and pyrexia.

Using Simulation-Based Training to Improve Neonatal Resuscitation Clinical Competency, Confidence, and Comfort Level of NICU Caregivers.

Approximately 10% of newborns require resuscitation at delivery or during a neonatal intensive care unit (NICU) stay. Neonatal intensive care unit caregivers competent in providing neonatal resuscitation decrease perinatal mortality and improve neonatal outcomes. Infrequency of resuscitation events, lack of repetition, and inexperience leave caregivers feeling un-prepared for emergency situations. There is a need for educational strategies to maintain competency and increase confidence and comfort level. This quality improvement project used a pre-post survey design. Competency was assessed during simulated mock codes using the Creighton Competency Evaluation Instrument. Self-perceived confidence and comfort level were assessed using a pre-post survey. Descriptive statistics indicated that the average score on the Creighton Competency Evaluation Instrument fell below the targeted minimally competent goal of 80%. Practical significance was noted between the pre-intervention and post-intervention means of both perceived confidence and comfort level. Simulation-based education may increase the competency, confidence, and comfort level of NICU caregivers and should be conducted routinely. Similar projects could be replicated at other institutions to address continuing competency with neonatal resuscitation. [J Contin Educ Nurs. 2024;55(4):175-180.].

Survey of Pediatric Critical Care Fellows on Postresuscitation Debriefing.

Current guidelines recommend debriefing following medical resuscitations to improve patient outcomes. The goal of this study was to describe national trends in postresuscitation debriefing practices among pediatric critical care medicine (PCCM) fellows to identify potential gaps in fellow education. A 13-item survey was distributed to fellows in all 76 ACGME-accredited PCCM programs in the United States in the spring of 2021. The online survey addressed frequency and timing of debriefings following medical resuscitations, whether formal training is provided, which medical professionals are present, and providers' comfort level leading a debriefing. Results were analyzed using descriptive statistics. A total of 102 responses (out of a possible N of 536) were gathered from current PCCM fellows. All fellows (100%) reported participation in a medical resuscitation. Only 21% stated that debriefings occurred after every resuscitation event, and 44% did not follow a structured protocol for debriefing. While 66% reported feeling very or somewhat comfortable leading the debriefing, 19% felt either somewhat uncomfortable or very uncomfortable. A vast majority (92%) of participating fellows believed that debriefing would be helpful in improving team member performance during future resuscitations, and 92% expressed interest in learning more about debriefing. The majority of PCCM fellows do not receive formal training on how to lead a debriefing. Given that 74% of fellows in our study did not feel very comfortable leading a debriefing but almost universally expressed that this practice is useful for provider well-being and performance, there is a clear need for increased incorporation of debriefing training into PCCM curricula across the United States.

EVIDENCE FOR BENEFICIAL USE OF THE COMPENSATORY RESERVE MEASUREMENT IN GUIDING INTRAOPERATIVE RESUSCITATION: A PROSPECTIVE COHORT STUDY OF ORTHOTOPIC LIVER TRANSPLANT RECIPIENTS.

Introduction: The compensatory reserve measurement (CRM) is a continuous noninvasive monitoring technology that provides an assessment of the integrated capacity of all physiological mechanisms associated with responses to a hypovolemic stressor such as hemorrhagic shock. No prior studies have analyzed its use for intraoperative resuscitation guidance. Methods: A prospective observational study was conducted of 23 patients undergoing orthotopic liver transplant. Chart review was performed to identify timing of various intraoperative events. Data were compared based on predefined thresholds for existence of hemorrhagic shock: CRM lower than 40%, systolic blood pressure (SBP) lower than 90 mm Hg (SBP90), and heart rate (HR) higher than 100 beats per minute (HR100). Regression analysis was performed for predicting resuscitation events, and nonlinear eXtreme Gradient Boosting (XGBoost) models were used to compare CRM with standard vital sign measures. Results: Events where CRM dropped lower than 40% were 2.25 times more likely to lead to an intervention, whereas HR100 and SBP90 were not associated with intraoperative interventions. XGBoost prediction models showed superior discriminatory capacity of CRM alone compared with the model with SBP and HR and no difference when all three were combined (CRM-HR-SBP). All XGBoost models outperformed equivalent linear regression models. Conclusion: These results demonstrate that CRM can provide an adjunctive clinical tool that can augment early and accurate of hemodynamic compromise and promote goal-directed resuscitation in the perioperative setting.

Use of design thinking and human factors approach to improve situation awareness in the pediatric intensive care unit.

Optimal design of healthcare spaces can enhance patient care. We applied design thinking and human factors principles to optimize communication and signage on high risk patients to improve situation awareness in a new clinical space for the pediatric ICU. To assess the impact of these tools in mitigating situation awareness concerns within the new clinical space. We hypothesized that implementing these design-informed tools would either maintain or improve situation awareness. A 15-week design thinking process was employed, involving research, ideation, and refinement to develop and implement new situation awareness tools. The process included engagement with interprofessional clinical teams, scenario planning, workflow mapping, iterative feedback collection, and collaboration with an industry partner for signage development and implementation. Improved and updated communication devices and bedside mitigation plans. Process metrics included individual and shared situation awareness of PICU care teams and our patient outcome metric was the rate of cardiopulmonary resuscitation (CPR) events pre- and post-transition. When evaluating all patients, shared situation awareness for accurate high-risk status improved from 81% pre-transition to 92% post-transition (p = .006). When assessing individual care team roles, accuracy of patient high-risk status improved from 88% to 95% (p = .05) for RNs, 85% to 96% (p = .003) for residents, and 88% to 95% (p = .03) for RTs. There was no change in the rate of CPR events following the transition.
