The Pain Monitoring Device (PMD) monitor (Medasense Biometrics Ltd., Ramat Gan, Israel) uses the Nociception Level (NOL) index, a multiple parameter-derived index that has recently shown a good sensitivity and specificity to detect noxious stimuli. The aim of this study was to assess the latest version of the device (PMD200TM) on variations of the NOL response after standardized tetanic stimuli to study the correlation between remifentanil doses and NOL. ⋯ The NOL value after noxious stimulus decreased with incremental remifentanil doses, showing a significant inverse correlation between the NOL index and opioid doses. The sensitivity and specificity of NOL to discriminate between noxious and non-noxious stimuli suggests its interesting potential as a monitor of nociception intensity during anesthesia.

The legislation Bill C-14 legalized medical assistance in dying (MAiD) in Canada. After thorough assessments of eligibility by two clinicians, Bill C-14 allows for both intravenous-assisted death by a clinician (euthanasia) and prescription of oral medication for self-administration (assisted suicide). Nevertheless, since inception in June 2016, intravenous euthanasia is the main form of delivery of assisted death in Canada. ⋯ The goals for ideal oral MAiD medications are 100% effectiveness and minimal side effects, while ensuring that the needed dose is both palatable and deliverable in a tolerable oral volume. The Netherlands has the most experience worldwide and barbiturates have emerged as the most common, efficacious, and tolerable agents by patients. Based on this global experience and the over-arching goals for oral MAiD, we recommend the use of a secobarbital suspension combined with antiemetic prophylaxis.

Restrictive transfusion strategies have been advocated in critically ill patients. Nevertheless, considerable uncertainty exists regarding optimal transfusion thresholds in traumatic brain injury (TBI) patients because the injured brain is susceptible to hypoxemic damage. We aimed to identify the determinants of red blood cell (RBC) transfusion and the perceived optimal transfusion thresholds in adult patients with moderate-to-severe TBI. ⋯ In our survey about critically ill TBI patients, transfusion practice was found to be mainly influenced by the acuity of care, patient characteristics, and neuro-monitoring. Clinical equipoise regarding optimal transfusion strategy is believed to be mainly attributed to the lack of clear clinical evidence and guidelines. Appropriate randomized-controlled trials are required to determine the optimal transfusion strategies in TBI patients.
