Successful use of extended cardiopulmonary resuscitation followed by extracorporeal oxygenation after venlafaxine-induced takotsubo cardiomyopathy and cardiac arrest: a case report

Drug-induced cardiac arrest: a pharmacovigilance study from 2004-2024 based on FAERS database

Objective

Utilizing the FDA Adverse Event Reporting System (FAERS) database, this study conducts signal detection for drugs associated with cardiac arrest (CA), aiming to optimize clinical decision-making and ensure safer drug usage.

Methods

Adverse event reports related to CA from the first quarter of 2004 to the second quarter of 2024 were extracted from the FAERS database. Signal detection was conducted using the reporting odds ratio (ROR) and proportional reporting ratio (PRR) to identify drugs associated with an increased risk of CA.

Results

A total of 66,431 reports were analyzed, comprising 34,508 males (51.9%) and 31,923 females (48.1%). The majority of cases (71.8%) were reported by healthcare professionals, with adults (≥18 years old) representing the predominant group. Clinical outcomes showed that 67.2% of cases resulted in death. Out of 82 drugs with over 100 CA-related reports, 43 displayed positive signals. The top five drugs identified by ROR were: carisoprodol [ROR (95% CI): 34.13 (29.62-39.32)], sugammadex [ROR (95% CI): 26.93 (22.56-32.16)], regadenoson [ROR (95% CI): 20.00 (17.69-22.60)], alprazolam [ROR (95% CI): 12.82 (12.19-13.48)], and propofol [ROR (95% CI): 11.93 (10.61-13.41)]. In the system drug signal detection, musculo-skeletal system drugs ranked highest [ROR (95% CI): 30.99 (27.74-34.62)], followed by alimentary tract and metabolism drugs [ROR (95% CI): 4.75 (4.59-4.92)], nervous system drugs [ROR (95% CI): 4.51 (4.4-4.61)], anti-infective drugs [ROR (95% CI): 4.13 (3.74-4.57)], cardiovascular drugs [ROR (95% CI): 3.89 (3.78-4.01)], and antineoplastic and immunomodulating agents [ROR (95% CI): 2.16 (2.13-2.2)].

Conclusion

This study identifies over 40 drugs potentially associated with an elevated risk of CA based on FAERS data. Healthcare professionals should be particularly vigilant when prescribing these drugs, especially to patients with a history of heart disease, and ensure rigorous monitoring of their cardiac health.

Successful use of extracorporeal life support and hemadsorption in the context of venlafaxine intoxication requiring cardiopulmonary resuscitation: a case report

Venlafaxine is a serotonin and noradrenalin reuptake inhibitor prescribed as an antidepressant. Overdose clinically manifests with neurological, cardiovascular and gastrointestinal abnormalities based on, amongst others, serotonin syndrome and can be life-threatening due to cardiovascular collapse. Besides immediate decontamination via gastric lavage and inhibition of enteral absorption through active charcoal, successful hemadsorption with CytoSorb® has been reported. We present the case of a 17-year-old female who required extracorporeal life support (ECLS) for cardiovascular collapse as a result of life-threatening venlafaxine intoxication. Serial serum blood concentrations of venlafaxine/desmethylvenlafaxine on admission at a tertiary hospital (approx. 24 h after ingestion) and subsequently 6 h and 18 h thereafter, as well as on days 2 and 4, were measured. CytoSorb® was initiated 6 h after admission and changed three times over 72 h. The initial blood concentration of venlafaxine/desmethylvenlafaxine was 53.52 µmol/l. After 6 h, it declined to 30.7 µmol/l and CytoSorb® was initiated at this point. After 12 h of hemadsorption, the blood level decreased to 9.6 µmol/l. On day 2, it was down to 7.17 µmol/l and decreased further to 3.74 µmol/l. Additional continuous renal replacement therapy using CVVHD was implemented on day 5. The combination of hemadsorption, besides traditional decontamination strategies along maximal organ supportive therapy with ECLS, resulted in the intact neurological survival of the highest venlafaxine intoxication reported in the literature to date. Hemadsorption with CytoSorb® might help to reduce blood serum levels of venlafaxine. Swift clearance of toxic blood levels may support cardiovascular recovery after life-threatening intoxications.

Extracorporeal cardio-pulmonary resuscitation in poisoning: A scoping review article

Background

Extracorporeal cardiopulmonary resuscitation (ECPR) represents last-line salvage therapy for poisoning-induced cardiac arrest but no review has focused on this specific area.

Objective

This scoping review sought to evaluate the survival outcomes and characteristics of published cases of ECPR for toxicological arrest, with the aim of highlighting the potential and limitations of ECPR in toxicology.Eligibility Criteria.We searched PubMed and Cochrane for eligible papers from database inception to October 1, 2022 using the keywords "toxicology", "ECLS" and "CPR". References of included publications were searched to identify additional relevant articles. Qualitative synthesis was used to summarize the evidence.

Results

85 articles were chosen: 15 case series, 58 individual cases and 12 other publications that were analyzed separately due to ambiguity. ECPR may improve survival outcomes in selected poisoned patients, although the extent of benefit is unclear. As ECPR for poisoning-induced arrest may have better prognosis compared to from other aetiologies, it is likely reasonable to apply ELSO ECPR consensus guideline recommendations to toxicological arrest.Out-of-hospital cardiac arrest alone may not be sufficient grounds to deny ECPR if effective resuscitation had been promptly instituted. Poisonings involving membrane-stabilizing agents and cardio-depressive drugs, and cardiac arrests with shockable rhythms appear to have better outcomes. ECPR may permit excellent neurologically-intact recovery despite prolonged low-flow time of up to four hours. Early ECLS activation and pre-emptive catheter placement can significantly shorten time-to-ECPR and possibly improve survival.

Conclusion

As effects of poisoning may be reversible, ECPR can potentially support poisoned patients through the critical peri-arrest state.

Outcome in intoxicated patients transported by a physician-staffed helicopter in Japan from 2015 to 2020

Aim

We retrospectively investigated the current status of poisoned patients who had been transported by a physician-staffed helicopter emergency medical service and their final outcomes using data from the JAPAN DOCTOR HELICOPTER REGISTRY SYSTEM.

Methods

The following details of dispatch activity were collected from the database of the JAPAN DOCTOR HELICOPTER REGISTRY SYSTEM: patient age and sex, timing of dispatch request, presence of cardiac arrest, vital signs, medical intervention, main etiology of intoxication, and final outcome. The patients were divided into two groups: those with a good outcome and those with a poor outcome. The variables were compared between the two groups.

Results

A total of 336 patients were intoxicated. Psychotropic drug overdose was the dominant cause, followed by carbon monoxide and ethanol. The median Glasgow Coma Scale score was significantly higher in the good outcome group than in the poor outcome group. The rates of cardiac arrest, interventions to secure an airway and/or assist with ventilation, and drug administration were significantly lower in the good outcome group than in the poor outcome group. There were no records concerning the decontamination of the intoxicating substance at the scene or during air evacuation.

Conclusion

The study suggests that various factors may influence the outcomes of patients with different types of intoxication. These findings offer valuable insights that could help to establish effective treatment strategies and the operation of doctor helicopters for intoxicated patients.
