In November 2016, our institution switched from alfentanil to fentanyl for analgesia and sedation in adult patients receiving extracorporeal membrane oxygenation. There is no published evidence comparing the use of alfentanil with fentanyl for sedation in extracorporeal membrane oxygenation patients. We conducted a retrospective observational study to explore any significant differences in patient outcomes or in the prescribing of adjunct sedatives before and after the switch. ⋯ No differences in patient outcomes were found between extracorporeal membrane oxygenation patients sedated with alfentanil compared with fentanyl. There was a statistically significant reduction in some adjunctive sedatives in patients managed with a fentanyl-based regimen. Prospective studies are required to confirm these results.

The depth of anesthesia is commonly assessed in clinical practice by the patient's clinical signs. However, during cardiopulmonary bypass and hypothermia, common symptoms of nociception such as tachycardia, hypertension, sweating, or movement have low sensitivity and specificity in the description of the patient nociception and hypnosis, in particular, detecting nociceptive stimuli. Better monitoring of the depth of analgesia during hypothermia under cardiopulmonary bypass will avoid underdosage or overdosage of analgesia, especially opioids. ⋯ In this clinical trial, 39 patients were monitored during general anesthesia with coronary atherosclerosis cardiopathy who were elective for on-pump coronary artery bypass graft surgery under hypothermia. The changes and correlation between the consciousness index, bispectral index, and nociception index with respect to the temperature were compared in different timepoints at basic state, during cardiopulmonary bypass and after cardiopulmonary bypass. While the three neuromonitoring indices showed significant correlations with respect to the temperature, the nociception index and consciousness index showed the strongest sensitivities, indicating that these two indices could be an important means of intraoperative neuromonitoring during induced hypothermia under cardiopulmonary bypass.

The objective of the study is to describe an emergency procedure for left ventricle venting during veno-arterial extracorporeal life support for refractory cardiac arrest. Veno-arterial extracorporeal membrane oxygenation is widely used in refractory cardiac arrest but is characterized by an increase in left ventricle afterload, which may impair cardiac contractility improvement. Different left ventricle venting techniques are available. ⋯ We were able to withdraw extracorporeal life support organization on day 10 and discharged on day 54. Clinical explorations reveal a fulminant rocuronium-related hypersensitivity myocarditis. This salvage surgical technique using a modified central veno-arterial extracorporeal membrane oxygenation cannulation technique has efficiently decreased blood stasis and permitted rapid recovery.

Comparative Study Observational Study
The effect of extracorporeal cardiopulmonary resuscitation in re-arrest after survival event: a retrospective analysis.
The objectives of this study were to 1) identify the risk factors for predicting re-arrest and 2) determine whether extracorporeal cardiopulmonary resuscitation results in better outcomes than conventional cardiopulmonary resuscitation for managing re-arrest in out-of-hospital cardiac arrest patients. ⋯ Alternative methods that reduce the advanced cardiac life support duration should be considered to prevent re-arrest and attain good outcomes in out-of-hospital cardiac arrest patients. Extracorporeal cardiopulmonary resuscitation for re-arrest tended to show a good outcome compared to conventional cardiopulmonary resuscitation for re-arrest. Avoiding or immediately correcting hypotension may prevent re-arrest and improve the outcome of re-arrested patients.

A 7-week-old girl presented in severe shock to a local emergency department. During transfer to the quaternary pediatric hospital, the child had a cardiac arrest and cardiopulmonary resuscitation was commenced en route. Upon arrival to the pediatric intensive care unit, extracorporeal life support was initiated via trans-sternal cannulation. ⋯ Immunomodulatory therapy with immunoglobulin and glucocorticoid medication was commenced and the child was separated from extracorporeal life support after 48 hours. Our case highlights both an unusual presentation of Kawasaki disease and the role extracorporeal cardiopulmonary resuscitation can play in the treatment of this disease. It describes the youngest reported patient in the literature with Kawasaki disease rescued by extracorporeal cardiopulmonary resuscitation and highlights how extracorporeal life support therapy can facilitate appropriate investigations to resolve diagnostic uncertainty and treat the underlying condition.
