Opioids are a key risk factor for postoperative nausea and vomiting (PONV). As intravenous (i.v.) acetaminophen reduces postoperative pain and opioid requirements, one would expect i.v. acetaminophen to be associated with a lower incidence of opioid-induced side effects, including PONV. We conducted a systematic search using Medline and Cochrane databases supplemented with hand search of abstra...

Acetaminophen is the most commonly used analgesic-antipyretic medication in the United States. Acetaminophen overdose, a frequent cause of drug toxicity, has been recognized as the leading cause of fatal and non-fatal hepatic necrosis. N-Acetylcysteine is the recommended antidote for acetaminophen poisoning. Despite evidence on the efficacy of N-acetylcysteine for prevention of hepatic injury, ...

BACKGROUND Intravenous acetaminophen injection (paracetamol) is marketed in Europe for the management of acute pain. A repeated-dose, randomized, double-blind, placebo-controlled, three-parallel group study was performed to evaluate the analgesic efficacy and safety of intravenous acetaminophen as compared with its prodrug (propacetamol) and placebo. Propacetamol has been available in many Euro...

Acetaminophen is widely used in children, because its safety and efficacy are well established. Although the risk of developing toxic reactions to acetaminophen appears to be lower in children than in adults, such reactions occur in pediatric patients from intentional overdoses. Less frequently, acetaminophen toxicity is attributable to unintended inappropriate dosing or the failure to recogniz...

BACKGROUND Acetaminophen Psi Parameter (APP) is a composite of acetaminophen (paracetamol) level and lag time before N-acetylcysteine (NAC) therapy. The APP is a significant predictor of hepatotoxicity secondary to acute acetaminophen overdose. Acetaminophen Psi Nomogram (APN) was invented as a graphic analog of the APP for use in predicting individual patient's risk of hepatotoxicity. Clinical...

OBJECTIVES We sought to assess the incidence of acetaminophen-induced hypotension. Our secondary objectives were to describe systemic hemodynamic changes and factors associated with this complication. DESIGN Prospective observational study. SETTING Three ICUs. PATIENTS Adult patients requiring IV acetaminophen infusion. Arterial pressure was monitored via an arterial catheter for 3 hours....

Background: Previous studies have considered patent ductus arteriosus (PDA) a common finding in premature infants, leading to complications such as intracranial hemorrhage, necrotizing enterocolitis and pulmonary dysplasia. The aim of this study was to assess and compare the efficacy of oral ibuprofen and intravenous acetaminophen in the closure of arterial duct in premature newborns. We also e...

Background and Purpose: Although caudal block and acetaminophen have shown efficacy in postoperative pediatric pain management, they have not been compared in efficacy following peritoneoscopy. Patients and Methods: The study population were ASA I or II children from 55 weeks postconceptual age to 10 years of age having peritoneoscopy. They were randomly assigned to preoperative caudal block us...

BACKGROUND Acetaminophen use during pregnancy has been associated with a reduced risk of stillbirth and preterm birth, but findings are based on few studies with small numbers of exposed women. METHODS To examine whether prenatal exposure to acetaminophen reduces the risk of adverse pregnancy outcomes, we used data from the Danish National Birth Cohort. We also examined the combined potential...

BACKGROUND Electroconvulsive therapy (ECT) is a safe and efficient treatment for several severe psychiatric disorders, but its use is limited by side effects. Post-ECT headache is one of the commonest side effects. Preemptive analgesia is effective in post-surgical pain management. The most commonly used analgesic is acetaminophen (paracetamol). However, acetaminophen as a preemptive analgesic ...
