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...

Importance Acetaminophen (paracetamol) is used by a large proportion of pregnant women. Research suggests that acetaminophen use in pregnancy is associated with abnormal fetal neurodevelopment. However, it is possible that this association might be confounded by unmeasured behavioral factors linked to acetaminophen use. Objective To examine associations between offspring behavioral problems a...

BACKGROUND Acetaminophen-cysteine adducts (APAP-CYS) are a specific biomarker of acetaminophen exposure. APAP-CYS concentrations have been described in the setting of acute overdose, and a concentration >1.1 nmol/ml has been suggested as a marker of hepatic injury from acetaminophen overdose in patients with an ALT >1000 IU/L. However, the concentrations of APAP-CYS during therapeutic dosing, i...

OBJECTIVES To compare within the same individuals two typically prescribed doses of hydrocodone/acetaminophen and oxycodone/acetaminophen products for their subjective, psychomotor, and physiological effects in healthy volunteers. DESIGN A randomized, placebo-controlled, double-blind, crossover, six-session clinical laboratory study, enrolling 16 healthy participants (27.2 +/- 4.4 years of ag...

conclusions post-operative pain in rectal acetaminophen group was less than that in intravenous acetaminophen group, and rectal acetaminophen group demanded their first additional analgesic medication later. results data analysis indicated a significant relationship between reduction of postoperative pain and the use of intravenous or rectal acetaminophen (p = 0.0001); in group receiving iv ace...

PURPOSE The present study examines the relationship between the dose of acetaminophen reported to have been ingested by patients and the occurrence of serum acetaminophen levels above the 'possible toxicity' line in patients presenting at the hospital after acetaminophen overdose. The prognostic value of patient-reported dosage cut-offs of 8, 10 and 12 g was determined. METHODS This retrospec...

Acetaminophen is a leading cause of acute liver failure (ALF). Genetic differences might predispose some individuals to develop ALF. In this exploratory study, we evaluated genotype frequency differences among patients enrolled by the ALF Study Group who had developed ALF either intentionally from a singletime-point overdose of acetaminophen (n = 78), unintentionally after chronic high doses of...

AANA Journal  June 2017  Vol. 85, No. 3 181 Adding intravenous (IV) acetaminophen to an opioidbased regimen as multimodal pain management for perioperative pain control in adults undergoing spine surgery can lead to effective pain control, reduce the risk of opioid-related adverse effects, and facilitate postoperative neurologic evaluation for surgical outcomes. This descriptive pilot study i...

BACKGROUND Parents often do not consider fever as an important physiological response and mechanism of defense against infections that leads to inappropriate use of antipyretics and potentially dangerous side effects. This study is designed to evaluate the appropriateness of antipyretics dosages generally administered to children with fever, and to identify factors that may influence dosage acc...

BACKGROUND It has been observed that acetaminophen potentiates the analgesic effect of morphine and tramadol in postoperative pain management. Its capacity as an analgesic drug or in combinations thereof to reduce the minimum alveolar concentration (MAC) of inhalational anesthetics represents an objective measure of this effect during general anesthesia. In this study, the effect of acetaminoph...
