BACKGROUND Opioid therapy is an increasingly used modality for treatment of musculoskeletal pain despite multiple associated risks. The purpose of this study was to evaluate how preoperative opioid use affects early outcomes after total joint arthroplasty. METHODS A total of 174 patients undergoing total joint arthroplasty were matched by age, gender, and procedure into 3 groups stratified by...

during a cross-sectional study, patients who were admitted to the orthopedic department of the urmia university of medical sciences were asked about opium/opioid abuse. demographic characteristics, the pattern of consumption, the substance, the duration of the use, the duration of hospital stay and the cause of their injuries were recorded. among 2,867 patients, 74 (2.5%) patients (71 men and 3...

Background Although intravenous (i.v.) lidocaine is used as a perioperative analgesic in abdominal surgery, evidence of efficacy is limited. The infusion dose and duration remain unclear. This study aimed to investigate the effect of a longer low-dose 48-hour infusion regimen on these outcomes. Methods Fifty-eight adults undergoing elective open colorectal surgery were randomized into the lid...

BACKGROUND Neuropathic pain is associated with several sensory abnormalities, including allodynia as well as spontaneous pain. Opioid intake in neuropathic pain patients is motivated by alleviation of both pain and allodynia. However, laboratory animal studies rely almost exclusively on reflexive withdrawal measures of allodynia. The authors examined the pharmacology of self-regulated intake of...

Dexmedetomidine is a selective α-2 adrenoceptor agonist with anxiolytic, sedative, and analgesic properties that prolongs analgesia and decreases opioid-related side effects when used in neuraxial and perineural areas as a local anesthetics adjuvant. The current study was designed to evaluate the effects of a single perineural administration of dexmedetomidine without local anesthetics on narco...

BACKGROUND In Italy since the 38/2010 law concerning Palliative Care and pain therapy has been promulgated, the consumption of opioids started increasing. However, despite the availability of a large amount of data regarding opioid prescription, a database including all patients on chronic opioid therapy does not yet exist. METHODS Retrospective analysis of analgesic opioid consumption was pe...

Preclinical studies have demonstrated that opioid receptor agonists increase the rate of non-small cell lung cancer (NSCLC) growth and metastasis. Following institutional review board approval, we retrieved data on 901 patients who underwent surgery for NSCLC at MD Anderson Cancer Center. Comprehensive demographics, intraoperative data, and recurrence-free survival (RFS) and overall survival (O...

The objective of this study was to propose a rough but simple method for estimating the total population need for opioids for treating all various types of moderate and severe pain at the country, regional, and global levels. We determined per capita need of strong opioids for pain related to three important pain causes for 188 countries. These needs were extrapolated to the needs for all the v...

Potent opioids are excellent painkillers but their use is hampered by side-effects such as nausea, vomiting, bowel dysfunction, urinary retention, pruritus, sedation and respiratory depression. Co-analgesics are often combined with opioids to reduce the prevalence of these unwanted effects while maintaining or even improve the quality of analgesia. A search of the recent literature demonstrated...

BACKGROUND While a number of pharmacological interventions exist for the treatment of opioid use disorder, evidence evaluating the effect of pain on substance use behavior, attrition rate, and physical or mental health among these therapies has not been well established. We aim to evaluate these effects using evidence gathered from a systematic review of studies evaluating chronic non-cancer pa...
