Ketamine and propofol have opposite effects on postanesthetic sleep architecture in rats: relevance to the endogenous sleep-wakefulness substances orexin and melanin-concentrating hormone.
Anesthesia and surgery disturb sleep. Disturbed sleep adversely affects postoperative complications involving the cardiovascular system, diabetes, and infection. General anesthetics share neuronal mechanisms involving endogenous sleep-wakefulness-related substances, such as orexin (OX) and melanin-concentrating hormone (MCH). We evaluated changes in sleep architecture and the concentration of OX and MCH during the peri-anesthetic period. ⋯ Anesthetics affect various endogenous sleep-wakefulness-related substances; however, the modulation pattern may depend on the type of anesthetic. The process of postanesthetic sleep disturbance was agent specific. Our results provide fundamental evidence to treat anesthetic-related sleep disturbance.

Randomized Controlled Trial Comparative StudyComparison of the analgesic effect of intravenous acetaminophen with that of flurbiprofen axetil on post-breast surgery pain: a randomized controlled trial.
Acetaminophen is known to be a relatively weak analgesic with fewer side effects than nonsteroidal anti-inflammatory drugs (NSAIDs). This study aimed to determine whether intravenous (iv) acetaminophen produces comparable analgesic effects to those of flurbiprofen (positive control drug), an intravenously injectable NSAID, after partial mastectomies. The primary outcome assessed was pain intensity during the first 24 h after the operation, and the secondary outcome was the satisfaction rating at discharge. ⋯ Acetaminophen produces an equivalent analgesic effect to flurbiprofen in post-partial mastectomy patients.
