Abstract
STUDY OBJECTIVE Evaluate the association between early naloxone use and outcomes after out-of-hospital cardiac arrest (OHCA) with initial non-shockable rhythms. METHODS This study was a secondary analysis of data collected in the Portland Cardiac Arrest Epidemiologic Registry, a database containing details of emergency medical services (EMS)-treated OHCA cases in the Portland, Oregon metropolitan region. Eligible patients had non-traumatic OHCA with an initial non-shockable rhythm and received naloxone by EMS or law enforcement prior to IV/IO access (exposure group). The primary outcome was ROSC at emergency department (ED) arrival. Secondary outcomes included survival to admission, survival to hospital discharge, and cerebral performance category score ≤2 at discharge (good neurologic outcome). We performed multivariable logistic regressions adjusting for age, sex, arrest location, witness status, bystander interventions, dispatch to EMS arrival time, initial rhythm, and county of arrest. RESULTS There were 1807 OHCA cases from 2018 to 2021 meeting eligibility criteria, with 57 receiving naloxone before vascular access. Patients receiving naloxone prior to vascular access attempts had higher adjusted odds (aOR [95% CI]) of ROSC at any time (2.14 [1.20-3.81]), ROSC at ED arrival (2.14 [1.18-3.88]), survival to admission (2.86 [1.60-5.09]), survival to discharge (4.41 [1.78-10.97]), and good neurologic outcome (4.61 [1.74-12.19]). CONCLUSIONS Patients with initial non-shockable OHCA who received law enforcement or EMS naloxone prior to IV/IO access attempts had higher adjusted odds of ROSC at any time, ROSC at ED arrival, survival to admission, survival to discharge, and good neurologic outcome.

Abstract
BACKGROUND Opioid-associated out-of-hospital cardiac arrest (OA-OHCA) is a subset of cardiac arrests that could benefit from measures outside of standard Advanced Cardiac Life Support (ACLS), such as naloxone. STUDY OBJECTIVES In this study, we sought to examine whether OHCA patients chosen for naloxone therapy by emergency medical services (EMS) clinicians in a system with high rates of opioid overdose would have increased rates of return of spontaneous circulation (ROSC) and survival to hospital discharge. METHODS The study took place in an urban EMS system with a high prevalence of opioid overdose. Paramedics could administer naloxone in cardiac arrest in addition to ACLS. It was often administered based on clinical gestalt for suspected OA-OHCA. The outcomes of OHCA patients who received naloxone were compared against those who received usual care in both an adjusted and unadjusted fashion. Lastly, we created a logistic regression model to test for an independent association of naloxone administration on ROSC and survival to hospital discharge. RESULTS A consecutive sample of 769 OHCA patients was obtained, of which 175 (23%) received naloxone. On average, patients who received naloxone had significantly fewer comorbidities and were younger. There was no difference in ROSC, survival to hospital discharge, or modified Rankin Scores. Using logistic regression modeling, there was no statistically significant effect of naloxone administration on these outcomes. CONCLUSION OHCA patients who received naloxone, despite being younger and having fewer comorbidities, had similar outcomes compared to those who received usual care. The difference in baseline characteristics suggests that paramedic gestalt reasonably selected for OA-OHCA.

Abstract
Recent increases in pediatric and adolescent opioid fatalities mandate an urgent need for early consideration of possible opioid exposure and specific diagnostic and management strategies and interventions tailored to these unique populations. In contrast to adults, pediatric methods of exposure include accidental ingestions, prescription misuse, and household exposure. Early recognition, appropriate diagnostic evaluation, along with specialized treatment for opioid toxicity in this demographic are discussed. A key focus is on Naloxone, an essential medication for opioid intoxication, addressing its unique challenges in pediatric use. Unique pediatric considerations include recognition of accidental ingestions in our youngest population, critical social aspects including home safety and intentional exposure, and harm reduction strategies, mainly through Naloxone distribution and education on safe medication practices. It calls for a multifaceted approach, including creating pediatric-specific guidelines, to combat the opioid crisis among children and to work to lower morbidity and mortality from opioid overdoses.

Abstract
Opioid overdose is the leading cause of death for Americans 25 to 64 years of age, and opioid use disorder affects >2 million Americans. The epidemiology of opioid-associated out-of-hospital cardiac arrest in the United States is changing rapidly, with exponential increases in death resulting from synthetic opioids and linear increases in heroin deaths more than offsetting modest reductions in deaths from prescription opioids. The pathophysiology of polysubstance toxidromes involving opioids, asphyxial death, and prolonged hypoxemia leading to global ischemia (cardiac arrest) differs from that of sudden cardiac arrest. People who use opioids may also develop bacteremia, central nervous system vasculitis and leukoencephalopathy, torsades de pointes, pulmonary vasculopathy, and pulmonary edema. Emergency management of opioid poisoning requires recognition by the lay public or emergency dispatchers, prompt emergency response, and effective ventilation coupled to compressions in the setting of opioid-associated out-of-hospital cardiac arrest. Effective ventilation is challenging to teach, whereas naloxone, an opioid antagonist, can be administered by emergency medical personnel, trained laypeople, and the general public with dispatcher instruction to prevent cardiac arrest. Opioid education and naloxone distributions programs have been developed to teach people who are likely to encounter a person with opioid poisoning how to administer naloxone, deliver high-quality compressions, and perform rescue breathing. Current American Heart Association recommendations call for laypeople and others who cannot reliably establish the presence of a pulse to initiate cardiopulmonary resuscitation in any individual who is unconscious and not breathing normally; if opioid overdose is suspected, naloxone should also be administered. Secondary prevention, including counseling, opioid overdose education with take-home naloxone, and medication for opioid use disorder, is important to prevent recurrent opioid overdose.

Abstract
BACKGROUND We have recently demonstrated that a significant proportion of fatal out-of-hospital cardiac arrests (OHCAs) are precipitated by occult overdose, which could benefit from antidote therapy administered adjunctively with other cardiac resuscitation measures. We sought to develop simple decision instruments that EMS providers and other first responders can use to rapidly identify occult opioid overdose-associated OHCAs. METHODS We examined data from February 2011 through December 2017 in the Postmortem Systematic Investigation of Sudden Cardiac Death study, in which San Francisco (California) County EMS-attended OHCA deaths received autopsy and expert panel adjudication of cause of death. Using classification tree analyses, we derived highly sensitive and specific decision instruments that predicted our primary outcome of occult opioid OD-associated OHCA. We then calculated screening performance characteristics of these instruments. RESULTS Of 767 OHCA deaths, 80 (10.4%) were associated with occult opioid overdose. Of the eight models with 100% sensitivity for opioid overdose-associated cardiac arrest, the highest specificity model (23.4%, 95% confidence interval [CI] 20.3-26.7%) was age < 60 years OR race = black or non-Latinx white OR arrest in public place. The highest specificity instrument (96.3%, 95% CI 94.6-97.5%) consisting of age < 60 years AND race = black or non-Latinx white AND unwitnessed arrest AND female sex had 25% (95% CI 16-35.9%) sensitivity. CONCLUSIONS We have derived simple decision instruments that can identify patients whose OHCA precipitant was occult opioid overdose. These instruments may be used to guide selective administration of the antidote naloxone in OHCA resuscitations.

Abstract
Opioid drugs are the first line of defense in severe pain but the adverse effects associated with opioids are considered as a serious issue worldwide. Acupuncture/electroacupuncture is a type of Chinese medicine therapy which is an effective analgesic therapy, well documented in animals and human studies. Electroacupuncture stimulation could release endogenous opioid peptides causing analgesia in a variety of pain models. It can be used as an alternative therapy to control the opioid crisis.

Abstract
Managing out-of-hospital cardiac arrest involves unique challenges, including delays in the initiation of advanced interventions and a limited number of trained personnel on scene. Recent out-of-hospital randomized controlled trials, systematic reviews, and metaanalyses provide key insights into what interventions are best proven to positively impact patient outcomes from out-of-hospital cardiac arrest. We review the literature on medications used in out-of-hospital cardiac arrest and summarize evidence-based guidelines from the American Heart Association that form the basis for most emergency medical services cardiac arrest protocols across the United States.

Abstract
Introduction Pre-hospital termination of resuscitation (TOR) is not a usual practice in many cities. The current study aimed to examine the reliability of the modified basic life support (ED-BLS) and advanced life support (ED-ALS) rules for TOR after patient arrival at the emergency department (ED). Methods In this retrospective cohort study, adult non-traumatic cardiac arrest patients who received pre-hospital basic life support and defibrillator (BLS-D) mode of service in Taoyuan County in northern Taiwan during the study period were assessed. Data were retrieved from web-based registry records. Results Of the 1612 patients included, 40 (2.5%) achieved survival to discharge. The ED-ALS rule showed higher specificity (ED-ALS rule: 82.5% {95% confidence interval [CI]: 68.1-91.3} vs. ED-BLS rule: 50.0% {95%CI: 35.2-64.8}) and positive predictive value (ED-ALS rule: 99.0% {95% CI: 97.9-99.5} vs. ED-BLS rule: 98.6% {95%CI: 97.8-99.1}) than the ED-BLS rule in terms of predicting no survival to discharge after patient arrival at the ED. Among patients who fulfilled all criteria for the ED-BLS and ED-ALS rule, 20 (1.4%) and seven (1.0%) survived to discharge, respectively. Application of the ED-BLS and ED-ALS rules could have reduced further resuscitation efforts after arrival at the ED by 86.4% and 43.1%, respectively. Conclusion For non-traumatic out-of-hospital cardiac arrest patients who receive BLS-D service, the ED-ALS rule has a higher specificity and PPV than the ED-BLS rule to predict no survival to discharge after patient arrival at the ED. Using the ED-ALS rule to terminate resuscitation after arrival at the ED should be prospectively validated. (Hong Kong j.emerg.med. 2014;21:283-290)

Abstract
STUDY OBJECTIVE Naloxone, an opioid-antagonist deliverable by an intra-nasal route, has become widely available and utilized by law enforcement officers as well as basic life support (BLS) providers in the prehospital setting. This study aimed to determine the frequency of repeat naloxone dosing in suspected narcotic overdose (OD) patients and identify patient characteristics. METHODS A retrospective chart review of patients over 17 years of age with suspected opioid overdose, treated with an initial intranasal (IN) dose of naloxone and subsequently managed by paramedics, was performed from April 2014 to June 2016. Demographic data was analyzed using descriptive statistics to identify those aspects of the history, physical exam findings. Results: A sample size of 2166 patients with suspected opioid OD received naloxone from first responders. No patients who achieved GCS 15 after treatment required redosing; 195 (9%) received two doses and 53 patients received three doses of naloxone by advanced life support. Patients were primarily male (75.4%), Caucasian (88.2%), with a mean age of 36.4 years. A total of 76.7% of patients were found in the home, 23.1% had a suspected mixed ingestion, and 27.2% had a previous OD. Two percent of all patients required a third dose of naloxone. CONCLUSION In this prehospital study, we confirmed that intranasal naloxone is effective in reversing suspected opioid toxicity. Nine percent of patients required two or more doses of naloxone to achieve clinical reversal of suspected opioid toxicity. Two percent of patients received a third dose of naloxone.

Abstract
Naloxone administration is an important component of resuscitation attempts by emergency medical services (EMS) for opioid drug overdoses. However, EMS providers must first recognize the possibility of opioid overdose in clinical encounters. As part of a public health response to an outbreak of opioid overdoses in Rhode Island, we examined missed opportunities for naloxone administration and factors potentially influencing EMS providers' decision to administer naloxone. We reviewed medical examiner files on all individuals who died of an opioid-related drug overdose in Rhode Island from January 1, 2012 through March 31, 2014, underwent attempted resuscitation by EMS providers, and had records available to assess for naloxone administration. We evaluated whether these individuals received naloxone as part of their resuscitation efforts and compared patient and scene characteristics of those who received naloxone to those who did not receive naloxone via chi-square, t-test, and logistic regression analyses. One hundred and twenty-four individuals who underwent attempted EMS resuscitation died due to opioid overdose. Naloxone was administered during EMS resuscitation attempts in 82 (66.1%) of cases. Females were nearly three-fold as likely not to receive naloxone as males (OR 2.9; 95% CI 1.2-7.0; p-value 0.02). Additionally, patients without signs of potential drug abuse also had a greater than three-fold odds of not receiving naloxone (OR 3.3; 95% CI 1.2-9.2; p-value 0.02). Older individuals, particularly those over age 50, were more likely not to receive naloxone than victims younger than age 30 (OR 4.8; 95% CI 1.3-17.4; p-value 0.02). Women, older individuals, and those patients without clear signs of illicit drug abuse, were less likely to receive naloxone in EMS resuscitation attempts. Heightened clinical suspicion for opioid overdose is important given the recent increase in overdoses among patients due to prescription opioids.

Abstract
OBJECTIVES We determined the factors that affect naloxone (Narcan) administration in drug overdoses, including the certification level of emergency medical technicians (EMTs). METHODS In 2012, 42 states contributed all or a portion of their ambulatory data to the National Emergency Medical Services Information System. We used a logistic regression model to measure the association between naloxone administration and emergency medical services certification level, age, gender, geographic location, and patient primary symptom. RESULTS The odds of naloxone administration were much higher among EMT-intermediates than among EMT-basics (adjusted odds ratio [AOR] = 5.4; 95% confidence interval [CI] = 4.5, 6.5). Naloxone use was higher in suburban areas than in urban areas (AOR = 1.41; 95% CI = 1.3, 1.5), followed by rural areas (AOR = 1.23; 95% CI = 1.1, 1.3). Although the odds of naloxone administration were 23% higher in rural areas than in urban areas, the opioid drug overdose rate is 45% higher in rural communities. CONCLUSIONS Naloxone is less often administered by EMT-basics, who are more common in rural areas. In most states, the scope-of-practice model prohibits naloxone administration by basic EMTs. Reducing this barrier could help prevent drug overdose death.

Abstract
OBJECTIVE To evaluate the hemodynamic and metabolic effects of terlipressin and naloxone in cardiac arrest. METHODS Cardiac arrest in rats was induced by asphyxia and maintained for 3.5 minutes. Animals were then resuscitated and randomized into one of six groups: placebo (n = 7), epinephrine (0.02 mg/kg; n = 7), naloxone (1 mg/kg; n = 7) or terlipressin, of which three different doses were tested: 50 µg/kg (TP50; n = 7), 100 µg/kg (TP100; n = 7) and 150 µg/kg (TP150; n = 7). Hemodynamic variables were measured at baseline and at 10 (T10), 20 (T20), 30 (T30), 45 (T45) and 60 (T60) minutes after cardiac arrest. Arterial blood samples were collected at T10, T30 and T60. RESULTS The mean arterial pressure values in the TP50 group were higher than those in the epinephrine group at T10 (165 vs. 112 mmHg), T20 (160 vs. 82 mmHg), T30 (143 vs. 66 mmHg), T45 (119 vs. 67 mmHg) and T60 (96 vs. 66.8 mmHg). The blood lactate level was lower in the naloxone group than in the epinephrine group at T10 (5.15 vs. 10.5 mmol/L), T30 (2.57 vs. 5.24 mmol/L) and T60 (2.1 vs. 4.1 mmol/L). CONCLUSIONS In this rat model of asphyxia-induced cardiac arrest, terlipressin and naloxone were effective vasopressors in cardiopulmonary resuscitation and presented better metabolic profiles than epinephrine. Terlipressin provided better hemodynamic stability than epinephrine.

Abstract
OBJECTIVE To present a series of evidence-based, consensus guidelines for veterinary CPR in dogs and cats. DESIGN Standardized, systematic evaluation of the literature, categorization of relevant articles according to level of evidence and quality, and development of consensus on conclusions for application of the concepts to clinical practice. Questions in five domains were examined: Preparedness and Prevention, Basic Life Support, Advanced Life Support, Monitoring, and Post-Cardiac Arrest Care. Standardized worksheet templates were used for each question, and the results reviewed by the domain members, by the RECOVER committee, and opened for comments by veterinary professionals for 4 weeks. Clinical guidelines were devised from these findings and again reviewed and commented on by the different entities within RECOVER as well as by veterinary professionals. SETTING Academia, referral practice and general practice. RESULTS A total of 74 worksheets were prepared to evaluate questions across the five domains. A series of 101 individual clinical guidelines were generated. In addition, a CPR algorithm, resuscitation drug-dosing scheme, and postcardiac arrest care algorithm were developed. CONCLUSIONS Although many knowledge gaps were identified, specific clinical guidelines for small animal veterinary CPR were generated from this evidence-based process. Future work is needed to objectively evaluate the effects of these new clinical guidelines on CPR outcome, and to address the knowledge gaps identified through this process.
