Intraoperative methadone administration and postoperative pain control: a systematic review and meta-analysis

Postoperative pain is not adequately managed in greater than 40% of surgical patients and is a high priority for perioperative research. In this meta-analysis, we examined studies comparing postoperative opioid consumption and pain scores in surgical patients who received methadone by any route vs those who received another opioid by any route. Studies were identified from PubMed, Cochrane, Web of Science, EMBASE, and Scopus from January 1966 to November 2018. Pooled odds ratios were calculated for a primary outcome of postoperative opioid consumption and secondary outcomes of time-to-extubation, time-to-first postoperative analgesia request, satisfaction, hospital length-of-stay, and complications. Postoperative pain scores were assessed qualitatively. Ten studies (617 patients) were included. Postoperative opioid consumption at 24 hours was lower in the methadone group vs control (mean difference = −15.22 mg oral morphine equivalents, 95% confidence interval −27.05 to −3.38; P = 0.01). Patients in the methadone group generally reported lower postoperative pain scores in 7 of 10 studies. Meta-analysis revealed greater satisfaction scores with analgesia in the methadone group vs control (0-100 visual analog scale; mean difference = 7.16, 95% confidence interval 2.30-12.01; P = 0.004). There was no difference in time-to-extubation, time-to-first analgesia request, hospital length-of-stay, or complications (nausea, sedation, respiratory depression, and hypoxem...

DiscussionIn hindsight I feel there are very few alternative causes for an ECG like this other than an acute LAD occlusion. I believe this is one of those'subtle STEMI'cases where neither the ECG nor the symptoms are very obvious or severe and the usual evolution is not seen.I think of these cases as'insidious infarcts'and I have seen this in all infarct territories and I do not think they are particularly rare. Essentially the patient is fairly comfortable and the ECG is not obvious but the patient ended up with Q waves, huge troponins and we missed the opportunity to reperfuse the artery when it counts. These patients te...

Authors: Patel P, Konala VM, Adapa S, Gayam V, Sahasranam P, Bose S, Golez CD, Naramala S Abstract Cyanide is notoriously known to the public for more than a century now as a weapon of mass destruction (Zyklon B gas - hydrogen cyanide used by Nazis), an agent for chemical warfare during World War I (hydrogen cyanide) and very infamous "Suicide Pill" used in the past by military and espionage organizations during World War II (potassium cyanide). During the modern industrial era, cyanide poisoning is commonly associated with the industrial exposure and domestic fires. But there is little awareness about po...

However, behind its familiar face, Marfan syndrome hides less well-known features.Areas covered: The German Marfan Organization listed unusual symptoms and clinical experts reviewed the literature on clinical features of Marfan syndrome not listed in the Ghent nosol...

This study examines the interaction of multiple comorbidities, including anxiety, depression, chronic pain, and hernia characteristics with outcomes after OVHR.MethodsPatients with anxiety were identified in an existing, prospectively collected, data set of OVHR with preoperative work-up including CT scans (2007 –2018). A patient with a diagnosis or prescription for anxiolytics, anti-depressants, or narcotics was considered to have anxiety, depression, or chronic pain, respectively. Hernia characteristics were analyzed using 3D volumetric software. Univariate and multivariate analyses were performed to as sess for th...

Written by Pendell Meyers, submitted by Siva Vittozzi-WongA man in his 30s with history of hypertension, hyperlipidemia, and diabetes presented with chest pain which started 12 hours prior to presentation. The pain was described as pressure, constant for 12 hours, radiating to the jaw, with left arm numbness. Initial vitals were significant for bradycardia at 45 beats per minute.Here is his presenting ECG with active pain:What do you think?Here was the prior EKG on file:The emergency medicine resident (who has received lectures from me on hyperacute T-waves, suble OMI, etc) documented the following interpretation:" In...

Written by Meyers, edits by SmithA 50-ish year old man was working construction when he suddenly collapsed. Coworkers started CPR within 1 minute of collapse. EMS arrived within 10 minutes and continued CPR and ACLS, noting alternating asystole and sinus bradycardia during rhythm checks. He received various ACLS medications and arrived at the ED with a perfusing rhythm.Initial vitals included heart rate around 100 bpm and BP 174/96. Here is his initial ECG, very soon after ROSC:What do you think?Sinus tachycardia.  There is incomplete RBBB (QRS duration less than 120 ms).  There is diffuse STD, maximal in V4-V5 a...

Case written and submitted by Ryan Barnicle MD, with edits by Pendell MeyersWhile vacationing on one of the islands off the northeast coast, a healthy 70ish year old male presented to the island health center for an evaluation of chest pain. The chest pain started about one hour prior to arrival while bike riding. It was a constant ache on the left side of his chest that forced him to stop cycling and call for an ambulance. It was radiating to his bilateral upper arms. It was associated with nausea but he denied dyspnea, dizziness, and headache.He explained that he had the same chest pain the day prior as well, on and off....

We report 65 studies, 51 patients (mean age of 13  ± 4 years; 75% males), with aortic stenosis (AS) who had a maximal exercise test between 2005 and 2016. We defined three groups based on resting mean Doppler gradient across their aortic valve: severe AS (n = 10; gradient of ≥ 40 mmHg), moderate AS (n = 20; gradient 25–39 mmHg), and mild AS (n = 35; gradient ≤ 24 mmHg). We studied symptoms (chest pain) during exercise, resting electrocardiogram changes (left ventricular hypertrophy [LVH]), complex arrh...

Abstract Adenosine is a purine nucleoside, responsible for the regulation of a wide range of physiological and pathophysiological conditions by binding with four G-protein-coupled receptors (GPCRs), namely A1, A2A, A2B and A3 adenosine receptors (ARs). In particular, A1 AR is ubiquitously present, mediating a variety of physiological processes throughout the body, thus represents a promising drug target for the management of various pathological conditions. Agonists of A1 AR are found to be useful for the treatment of atrial arrhythmia, angina, type-2 diabetes, glaucoma, neuropathic pain, epilepsy, depression and ...
