Comparative Study
Direct comparison of 20-hour IV, 36-hour oral, and 72-hour oral acetylcysteine for treatment of acute acetaminophen poisoning.
There is no general consensus among clinicians on the superior route or duration of treatment with N-acetylcysteine (NAC) for acute acetaminophen (APAP) poisoning, and head-to-head studies comparing intravenous (IV) and oral NAC have not been done. Recent 20-hour IV NAC protocol failures in the United States prompted some to question its safety. Our objective was to determine if treatment with the 20-hour IV NAC protocol results in clinical outcomes different from the longer 36-hour oral or 72-hour oral NAC protocols in cases of acute APAP poisoning. ⋯ No cases of transplant or death occurred, and secondary outcomes were rare. When administered within 8 hours of acute APAP poisoning, the 20-hour IV treatment protocol was as effective as the longer 36-hour oral and 72-hour oral treatment protocols. Further study is needed to determine outcome differences between IV and oral NAC when treatment is initiated >8 hours after overdose or in cases of coingestion with other drugs.

The objective of this modeling study was to assess different dosage regimens that might be used to guide clinicians in transitioning patients from gabapentin to pregabalin therapy when such a transition is clinically warranted. Two different gabapentin to pregabalin transition designs were simulated based on their respective population pharmacokinetic profiles. The first design involved immediate discontinuation of gabapentin therapy with initiation of pregabalin therapy at the next scheduled dose period. ⋯ The pharmacokinetic simulations show that during the transition period in both designs, predicted pregabalin-equivalent concentrations did not depart from those calculated during periods of steady-state gabapentin or pregabalin monotherapy. Transition from gabapentin to pregabalin was seamless and rapid, with predicted pregabalin-equivalent concentrations highly comparable with plasma pregabalin concentrations within 1 day of pregabalin initiation in the immediate discontinuation model and within 1 day of gabapentin cessation in the gradual discontinuation model. These data suggest that transitioning patients from gabapentin to pregabalin could theoretically be achieved by either of the 2 approaches assessed.

Sepsis and septic shock remain a major cause of morbidity and mortality. The complexity of the disease pathophysiology has resulted in a rich area of research on etiology and therapeutics. Anesthesiologists will often encounter the syndrome in their routine practice. This review summarizes some of the basic concepts of therapeutics and some novel therapeutics that are pertinent to anesthesia.

Randomized Controlled Trial
Pregabalin for the treatment of abdominal adhesion pain: a randomized, double-blind, placebo-controlled trial.
Chronic pain related to postoperative abdominal adhesions is a common problem with no standard analgesic regimen currently established. In a double-blind, placebo-controlled trial, we examined the effects of pregabalin on pain modulation in patients with prior abdominal surgery and documented adhesion. The primary outcome measure was pain relief documented by a 2-point change on the Likert pain scale with a secondary pain measure of sleep interruption. ⋯ The pain score result from the blinded phase setting indicated that the amount of decrease was significantly greater in the drug group (P = 0.024), whereas the pain score result from the open-label setting indicated that the amount of decrease was significantly greater in the placebo group (P = 0.043). Only the sleep score result in the open-label setting was significantly greater in the placebo group (P = 0.024). We conclude that pregabalin significantly reduced patient-documented pain scores compared with placebo in our small cohort of patients with abdominal adhesion pain.

Patient presented with passage of fresh blood mixed with clots per rectum. In the ER, she was found to have bright red blood per rectum with clots, with frank blood on nasogastric tube. She was on dabigatran for atrial fibrillation and aspirin, with intermittent intake of ibuprofen. ⋯ The patient was given plasmapheresis and hemoglobin and hematocrit stabilized. The patient was kept on continued mechanical ventilator support for the night and extubated next day. The hemodynamics stabilized and the patient was transferred to the general medical floors after 1 day of observation, after extubation.
