Analysis of an 8-hour acetylcysteine infusion protocol for repeated supratherapeutic ingestion (RSTI) of paracetamol.
In Australia, the treatment guideline for patients with repeated supratherapeutic ingestion (RSTI) of paracetamol recommends an abbreviated acetylcysteine regimen if the paracetamol concentration is low (<10 mg/L) and alanine aminotransferase (ALT) is normal or static after 8 hours of infusion. There are currently no studies of this recommendation. ⋯ An 8-hour acetylcysteine infusion regimen for treatment of paracetamol RSTI may be safe and is likely to reduce length of stay for patients at low risk of hepatotoxicity. Larger prospective studies are needed to examine the efficacy of this abbreviated acetylcysteine protocol.

Comparative Study
Combined Popliteal Catheter With Single-Injection vs Continuous-Infusion Saphenous Nerve Block for Foot and Ankle Surgery.
The increasing scope and complexity of foot and ankle procedures performed in an outpatient setting require more intensive perioperative analgesia. Regional anesthesia (popliteal and saphenous nerve blocks) has been proven to provide satisfactory pain management, decreased postoperative opioid use, and earlier patient discharge. This can be further augmented with the placement of a continuous-flow catheter, typically inserted into the popliteal nerve region. This study investigated the use of a combined popliteal and saphenous continuous-flow catheter nerve block compared to a single popliteal catheter and single-injection saphenous nerve block in postoperative pain management after ambulatory foot and ankle surgery. ⋯ Level II, prospective cohort study.

Observational StudyThe Effect of Acetaminophen on Temperature in Critically Ill Children: A Retrospective Analysis of Over 50,000 Doses.
Acetaminophen is widely used in PICUs. Although randomized controlled trials suggest that acetaminophen significantly reduces body temperature in adults, the effect of acetaminophen on temperature in critically ill children has not been previously quantified. ⋯ Acetaminophen is associated with a significant decrease in temperature in children with fever. However, temperature may decrease following fever without acetaminophen in the PICU. The threshold to use acetaminophen must be understood to determine the true effect on temperature in any future trials.

Accuracy of the paracetamol-aminotransferase product to predict hepatotoxicity in paracetamol overdose treated with a 2-bag acetylcysteine regimen.
Paracetamol concentration is a highly accurate risk predictor for hepatotoxicity following overdose with known time of ingestion. However, the paracetamol-aminotransferase multiplication product can be used as a risk predictor independent of timing or ingestion type. Validated in patients treated with the traditional, "three-bag" intravenous acetylcysteine regimen, we evaluated the accuracy of the multiplication product in paracetamol overdose treated with a two-bag acetylcysteine regimen. ⋯ The multiplication product accurately predicts hepatotoxicity when using a two-bag acetylcysteine regimen, especially in patients treated more than eight hours post-overdose. Further studies are needed to assess the product as a method to adjust for exposure severity when testing efficacy of modified acetylcysteine regimens.

Review Meta AnalysisInterventions for paracetamol (acetaminophen) overdose.
Paracetamol (acetaminophen) is the most widely used non-prescription analgesic in the world. Paracetamol is commonly taken in overdose either deliberately or unintentionally. In high-income countries, paracetamol toxicity is a common cause of acute liver injury. There are various interventions to treat paracetamol poisoning, depending on the clinical status of the person. These interventions include inhibiting the absorption of paracetamol from the gastrointestinal tract (decontamination), removal of paracetamol from the vascular system, and antidotes to prevent the formation of, or to detoxify, metabolites. ⋯ These results highlight the paucity of randomised clinical trials comparing different interventions for paracetamol overdose and their routes of administration and the low or very low level quality of the evidence that is available. Evidence from a single trial found activated charcoal seemed the best choice to reduce absorption of paracetamol. Acetylcysteine should be given to people at risk of toxicity including people presenting with liver failure. Further randomised clinical trials with low risk of bias and adequate number of participants are required to determine which regimen results in the fewest adverse effects with the best efficacy. Current management of paracetamol poisoning worldwide involves the administration of intravenous or oral acetylcysteine which is based mainly on observational studies. Results from these observational studies indicate that treatment with acetylcysteine seems to result in a decrease in morbidity and mortality, However, further evidence from randomised clinical trials comparing different treatments are needed.
