IntroductionPatients frequently present to the emergency department (ED) with migraine headaches. Although low-dose ketamine demonstrates analgesic efficacy for acute pain complaints in the ED, headaches have historically been excluded from these trials. This study evaluates the efficacy and safety of low-dose ketamine for treatment of acute migraine in the ED.MethodsThis randomized, double-blinded, placebo-controlled trial evaluated adults 18 to 65 years of age with acute migraine at a single academic ED. Subjects were randomized to receive 0.2 milligrams per kilogram of intravenous (IV) ketamine or an equivalent volume of normal saline. Numeric Rating Scale (NRS-11) pain scores, categorical pain scores, functional disability scores, side effects, and adverse events were assessed at baseline (T0) and 30 minutes post-treatment (T30). The primary outcome was between-group difference in NRS score reduction at 30 minutes.ResultsWe enrolled 34 subjects (ketamine=16, placebo=18). Demographics were similar between treatment groups. There was no statistically significant difference in NRS score reductions between ketamine and placebo-treated groups after 30 minutes. Median NRS score reductions at 30 minutes were 1.0 (interquartile range [IQR] 0 to 2.25) for the ketamine group and 2.0 (IQR 0 to 3.75) for the placebo group. Between-group median difference at 30 minutes was −1.0 (IQR −2 to 1, p=0.5035). No significant differences between treatment groups occurred in categorical pain scores, functional disability scores, rescue medication request rate, and treatment satisfaction. Side Effect Rating Scale for Dissociative Anesthetics scores in the ketamine group were significantly greater for generalized discomfort at 30 minutes (p=0.008) and fatigue at 60 minutes (p=0.0216). No serious adverse events occurred in this study.ConclusionWe found that 0.2mg/kg IV ketamine did not produce a greater reduction in NRS score compared to placebo for treatment of acute migraine in the ED. Generalized discomfort at 30 minutes was significantly greater in the ketamine group. Overall, ketamine was well tolerated by migraine-suffering subjects. To optimize low-dose ketamine as an acute migraine treatment, future studies should investigate more effective dosing and routes of administration.

PurposeTo assess the association between gynecologic oncologists’ stigma and palliative care referrals among advanced cancer patients. MethodsGynecologic oncologists were surveyed using validated measures to assess stigmatizing attitudes toward palliative care, anticipated stigma of palliative care, acceptance of palliative care, and willingness to refer to palliative care. Descriptive statistics were calculated. Analysis was performed using linear regression.Results1200 physicians received the survey and 108 (9%) completed it. Most were female (69.4%) and white (82.4%). Most practiced in academics (64.8%) in urban environments (71.3%). Respondents did not have anticipated stigma surrounding palliative care referral (mean score 1.89, range 1-7, higher score indicating more stigma), were accepting of palliative care (mean score 1.45, range 1-7, higher score indicating less acceptance), and were willing to refer patients to palliative care (mean score 5.75, range 1-7, higher score indicating more willingness to refer). Linear regression demonstrated females had less anticipated stigma surrounding palliative care (B=-0.213, p=0.04) and higher acceptance of palliative care (B=-0.244, p=0.01). Most surveyed derived satisfaction from work with advanced cancer patients (83%). Nineteen percent were depressed by managing advanced cancer patients. One fourth felt emotionally burned out by dealing with too many deaths. ConclusionsMost gynecologic oncologists did not exhibit stigma surrounding palliative care and derive satisfaction from their work. Some gynecologic oncologists experience depression and burnout related to their profession. This close connection with patients as they transition to the end of life may take a toll on providers.
