During the last 100 years, the role of anesthesiologists in psychiatry has focused primarily on facilitating electroconvulsive therapy and mitigating postoperative delirium and other perioperative neurocognitive disorders. The discovery of the rapid and sustained antidepressant properties of ketamine, and early results suggesting that other general anesthetic drugs (including nitrous oxide, propofol, and isoflurane) have antidepressant properties, has positioned anesthesiologists at a new frontier in the treatment of neuropsychiatric disorders. ⋯ This article presents a brief overview of anesthetic drugs as novel antidepressants and identifies promising future candidates for the treatment of depression. The authors issue a call to action and outline strategies to foster collaborations between anesthesiologists and psychiatrists as they work toward the common goals of repurposing anesthetic drugs as antidepressants and addressing mood disorders in surgical patients.

ReviewOpioid-free general anesthesia: considerations, techniques, and limitations.
To discuss the role of opioids during general anesthesia and examine their advantages and risks in the context of clinical practice. We define opioid-free anesthesia (OFA) as the absolute avoidance of intraoperative opioids. ⋯ Complete avoidance of intraoperative opioids remains questionable, as it does not necessarily ensure avoidance of postoperative opioids. Multimodal analgesia including local/regional anesthesia may allow OFA for selected, minimally invasive surgeries, but further research is necessary in surgeries with high postoperative opioid requirements. Until there is definitive evidence regarding procedure and patient-specific combinations as well as the dose and duration of administration of adjunct agents, it is imperative to practice opioid-sparing approach in the intraoperative period.

Centres dedicated to chronic postsurgical pain (CPSP) have been developed, but delays for accessing to it are generally long. Teleconsultation might be a means to facilitate access to care by allowing an initial triage. CPSPs are neuropathic pain in around half of the cases and their diagnosis is mainly based on the score obtained from validated questionnaires. Among them, those requiring a neurological examination (i.e. the Douleur Neuropathique en 4 questions [DN4]) have a better sensitivity and specificity, and should be preferred. However, effectiveness of a remote neurological examination remains to be established. The aim of this observational study is to check during a face-to-face consultation if, after a short training, a naïve patient is capable to self-assess the clinical signs of neuropathic sensations. ⋯ Our results suggest that self-assessment, carried out after brief training and using a simple tool, provides results comparable to those obtained by a specialist physician to diagnose symptoms of neuropathic pain. If the results of the current study are confirmed on a larger scale, self-assessment will help improve access to specialized chronic pain care by better orienting patients and opening up access to teleconsultations.

Observational Study
Does celecoxib prescription for pain management impact post-tonsillectomy hemorrhage requiring surgery? A retrospective observational cohort study.
Adenotonsillectomy and tonsillectomy (referred to as tonsillectomy hereafter) are common pediatric surgeries. Postoperative complications include hemorrhage requiring surgery (2 to 3% of cases) and pain. Although nonsteroidal anti-inflammatory drugs are commonly administered for postsurgical pain, controversy exists regarding bleeding risk with cyclooxygenase-1 inhibition and associated platelet dysfunction. Preliminary evidence suggests selective cyclooxygenase-2 inhibitors, for example celecoxib, effectively manage pain without adverse events including bleeding. Given the paucity of data for routine celecoxib use after tonsillectomy, this study was designed to investigate the association between postoperative celecoxib prescription and post-tonsillectomy hemorrhage requiring surgery using chart-review data from the Children's Hospital of Eastern Ontario. ⋯ Celecoxib does not significantly increase the odds of post-tonsillectomy hemorrhage requiring surgery, after adjusting for covariates. This large pediatric cohort study of celecoxib administered after tonsillectomy provides compelling evidence for safety but requires confirmation with a multisite randomized controlled trial.
