RESUMO

Cardiogenic shock (CS) represents a spectrum of hemodynamic deficits in which the cardiac output is insufficient to provide adequate tissue perfusion. The Impella (Abiomed Inc, Danvers, MA) device, a contemporary percutaneous ventricular support, is most often indicated for classic, deteriorating, and extremis Society for Coronary Angiography and Intervention stages of CS, which describe CS that is not responsive to optimal medical management and conventional treatment measures. Impella devices are an evolving field of mechanical support that is used with increasing frequency. Critical care transport medicine crews are required to transport patient support by the Impella device with increasing frequency. It is important that critical care transport medicine crews are familiar with the Impella device and are able to troubleshoot complications that may arise in the transport environment. This article reviews many aspects of the Impella device critical to the transport of this complex patient population.

RESUMO

BACKGROUND: Intrathecal baclofen (ITB) is a mainstay of treatment for patients with chronic spasticity. Up to 40% of all patients receiving ITB experience overdose or withdrawal symptoms, which in the most severe cases can lead to multisystem organ failure and death. There is currently no well-established treatment for ITB withdrawal. One previous case report details an intubated pediatric patient who underwent baclofen pump removal in which dexmedetomidine was used in combination with other medications to prevent baclofen withdrawal. CASE REPORT: We report a case of baclofen withdrawal where the decision was made to initiate a dexmedetomidine infusion, with subsequent improvement of the patient's hypertension and tachycardia. At no point during her stay did the patient require intubation for airway protection, and the patient was ultimately discharged to her previous nursing facility on hospital day 9 with no new neurologic deficits. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Emergency physicians should be aware of dexmedetomidine as a promising option for the treatment of ITB withdrawal in the acute setting. Although little evidence is currently present, dexmedetomidine was used successfully in this case, and should be considered as a temporizing treatment for ITB withdrawal. Dexmedetomidine holds promise in the management of ITB withdrawal compared to other previously described treatments, including oral baclofen, cyproheptadine, and dantrolene. In addition, dexmedetomidine has a superior safety profile compared to propofol or large doses of benzodiazepines. Further research will be useful in supporting the use of dexmedetomidine for this purpose.

RESUMO

BACKGROUND: Recent evidence suggest that extracorporeal cardiopulmonary resuscitation (ECPR) may improve survival rates for nontraumatic out-of-hospital cardiac arrest (OHCA). Eligibility criteria for ECPR are often based on patient age, clinical variables, and facility capabilities. Expanding access to ECPR across the U.S. requires a better understanding of how these factors interact with transport time to ECPR centers. METHODS: We constructed a Geographic Information System (GIS) model to estimate the number of ECPR candidates in the U.S. We utilized a Resuscitation Outcome Consortium (ROC) database to model time-dependent rates of ECPR eligibility and the Cardiac Arrest Registry to Enhance Survival (CARES) registry to determine the total number of OHCA patients who meet pre-specified ECPR criteria within designated transportation times. The combined model was used to estimate the total number of ECPR candidates. RESULTS: There were 588,203 OHCA patients in the CARES registry from 2013 to 2020. After applying clinical eligibility criteria, 22,104 (3.76%) OHCA patients were deemed eligible for ECPR. The rate of ROSC increased with longer resuscitation time, which resulted in fewer ECPR candidates. The proportion of OHCA patients eligible for ECPR increased with older age cutoffs. Only 1.68% (9,889/588,203) of OHCA patients in the U.S. were eligible for ECPR based on a 45-minute transportation time to an ECMO-ready center model. CONCLUSIONS: Less than 2% of OHCA patients are eligible for ECPR in the U.S. GIS models can identify the impact of clinical criteria, transportation time, and hospital capabilities on ECPR eligibility to inform future implementation strategies.
