Elizabeth Chiam, Rinaldo Bellomo, Leonid Churilov, Laurence Weinberg
The hemodynamic effects of intravenous (IV) paracetamol in patients undergoing cardiac surgery are unknown. We performed a prospective single center placebo controlled randomized study with parallel group design in adult patients undergoing elective cardiac surgery. Participants received paracetamol (1 gram) IV or placebo (an equal volume of 0.9% saline) preoperatively followed by two postoperative doses 6 hours apart. The primary endpoint was the absolute change in systolic (SBP) 30 minutes after the preoperative infusion, analysed using an ANCOVA model...

PURPOSE: Treatment patterns of carpal tunnel surgery by members of the American Society of Surgery of the Hand (ASSH) have recently been published. The majority of cases in this study were performed in the general operating room with intravenous (IV) sedation or a Bier block. Patients were most commonly prescribed hydrocodone for postoperative pain. The majority of carpal tunnel releases at our center are performed under local anesthesia alone, with plain acetaminophen (Tylenol) or codeine prescribed for postoperative pain...

BACKGROUND: This is an updated version of the original Cochrane review published in Issue 10, 2011. Paracetamol (acetaminophen) is the most commonly prescribed analgesic for the treatment of acute pain. It may be administered orally, rectally, or intravenously. The efficacy and safety of intravenous (IV) formulations of paracetamol, IV paracetamol, and IV propacetamol (a prodrug that is metabolized to paracetamol), compared with placebo and other analgesics, is unclear. OBJECTIVES: To assess the efficacy and safety of IV formulations of paracetamol for the treatment of postoperative pain in both adults and children...

BACKGROUND: In preterm newborns, the ductus arteriosus frequently fails to close and the infants require medical or surgical closure of the patent ductus arteriosus (PDA). A PDA can be treated surgically or medically with one of two prostaglandin inhibitors, indomethacin or ibuprofen. Case reports suggest that paracetamol may be an alternative for the closure of a PDA. Concerns have been raised that in neonatal mice paracetamol may cause adverse effects on the developing brain, and an association between prenatal exposure to paracetamol and later development of autism or autism spectrum disorder has been reported...

The Chikungunya (CHIKV) fever is a viral disease produced by a single-stranded RNA Alphavirus from the Togaviridae genus. Its transmission occurs only through mosquito vectors, principally Aedes aegypti. It requires a human-mosquito-human transmission cycle. It is associated with severe arthritis/arthralgias, myalgias, high fever, headache, and maculopapular rash. Joint ache appears to be symmetrical. The virus has an incubation period of 2 to 7 days, where the high fever is typically presented. It is followed by arthralgias and myalgias, and rashes, which last for 3 to 5 days...

BACKGROUND: Surgery of the tonsils often causes severe pain lasting for many days as been shown by data from the National Tonsil Surgery Register in Sweden. Tonsillotomy is associated with fewer readmissions due to bleeding, number of days requiring analgesics and health care contacts due to pain compared to tonsillectomy. The register data demonstrate the necessity of better-evidenced based pain treatment guidelines for tonsil-surgery. OBJECTIVES: To develop evidenced based pain treatment guidelines for tonsil-surgery in Sweden...

BACKGROUND: Pharmacokinetic estimates for intravenous paracetamol in individual adult cohorts are different to a certain extent, and understanding the covariates of these differences may guide dose individualization. In order to assess covariate effects of intravenous paracetamol disposition in adults, pharmacokinetic data on discrete studies were pooled. METHODS: This pooled analysis was based on 7 studies, resulting in 2755 time-concentration observations in 189 adults (mean age 46 SD 23 years; weight 73 SD 13 kg) given intravenous paracetamol...

OBJECTIVE: This study aimed to determine if intravenous acetaminophen [paracetamol] (IV APAP) could decrease visual analog pain scores (VAS), opioid exposure and subsequent opioid related adverse effects (nausea, vomiting, constipation) in spinal surgery patients. METHODS: Thirty four spinal surgery patients to date have received IV APAP since its addition to the formulary at our institution. The electronic medical record was accessed on all patients who received at least one dose pre or post operatively to collect postoperative opioid consumption (in morphine equivalents), number of antiemetic and laxative doses, use of naloxone, and VAS pain scores from arrival to surgical unit through postop day two...

BACKGROUND: Pediatric drug development is hampered by practical, ethical, and scientific challenges. Microdosing is a promising new method to obtain pharmacokinetic data in children with minimal burden and minimal risk. The use of a labeled oral microdose offers the added benefit to study intestinal and hepatic drug disposition in children already receiving an intravenous therapeutic drug dose for clinical reasons. OBJECTIVE: The objective of this study was to present pilot data of an oral [(14)C]paracetamol [acetaminophen (AAP)] microdosing study as proof of concept to study developmental pharmacokinetics in children...

Paracetamol (acetaminophen) overdose remains the leading cause of death or transplantation due to acute liver failure in many parts of the world. Acetylcysteine has long been recognized as an effective antidote, via oral or intravenous administration, minimizing the risk and severity of acute liver injury if administered sufficiently early after a paracetamol overdose. Despite this, its mechanisms of action remain obscure, and there is uncertainty regarding the optimal dose and duration of treatment. The intravenous infusion protocol was originally developed as a three-step loading regimen; it causes very high early peak plasma concentrations of acetylcysteine whereas the later maintenance infusion is associated with much lower concentrations...

BACKGROUND: Triptans are a family of selective serotonin (5-HT1B/1D) receptor agonists that are widely used to treat acute migraine attacks. Their efficacy is limited by side effects and the gastrointestinal manifestations of migraine. AIM: To compare the efficacy of a single intravenous administration of propacetamol, a prodrug of paracetamol (acetaminophen) with a single dose of oral rizatriptan in treating acute migraine attacks. METHODS: Patients were selected from those who presented to the emergency room with a diagnosed migraine attack and who had not previously taken any analgesics...
