Subanesthetic Dose of Esketamine Improves the Sedative and Analgesic Effects of Dexmedetomidine and Remifentanil in Liposuction Anesthesia: A Prospective, Double-Blinded, Randomized Controlled Trial.

Purpose: Esketamine have anesthetic and analgesic properties. This study aimed to observe the enhancing effect of subanesthetic doses of esketamine (0.15-0.

Estrogen alleviates acute and chronic itch in mice.

Itching is associated with various skin diseases, including atopic dermatitis and allergic dermatitis, and leads to repeated scratching behavior and unpleasant sensation. Although clinical and laboratory research data have shown that estrogen is involved in regulating itch, the molecular and cellular basis of estrogen in itch sensation remains elusive. In the present study, it was found that estrogen-treated mice exhibited reduced scratching bouts when challenged with histamine, chloroquine, the proteinase-activated receptor-2 activating peptide SLIGRL-NH2 (SLIGRL), compound 48/80, and 5-hydroxytryptamine when compared with mice in the placebo group.

Effects of multiple exposures to general anesthesia on the sleep quality of children after plastic surgery in Beijing, China: a cohort study.

To assess the effects of the number and duration of general anesthesia exposure on the sleep quality of 6-15-year-old school children who underwent plastic surgery. The study was conducted on 688 children who underwent plastic surgery between the ages of 6 and 15 years using the Sleep Disorder Scale for Children (SDSC). The children were divided into two groups according to their exposure to general anesthesia: No General Anesthesia (NGA) and General Anesthesia (GA) groups.

Prophylactic Penehyclidine Inhalation for Prevention of Postoperative Pulmonary Complications in High-risk Patients: A Double-blind Randomized Trial.

Background: Postoperative pulmonary complications are common. Aging and respiratory disease provoke airway hyperresponsiveness, high-risk surgery induces diaphragmatic dysfunction, and general anesthesia contributes to atelectasis and peripheral airway injury. This study therefore tested the hypothesis that inhalation of penehyclidine, a long-acting muscarinic antagonist, reduces the incidence of pulmonary complications in high-risk patients over the initial 30 postoperative days.

Prophylactic penehyclidine inhalation for prevention of postoperative pulmonary complications in high-risk patients: study protocol of a randomized controlled trial.

Background: Postoperative pulmonary complications (PPCs) are major causes of morbidity, mortality, and prolonged hospital stay in patients after surgery. Using effective strategies to prevent its occurrence is essential to improve outcome. However, despite various efforts, the incidence of PPCs remains elevated in high-risk patients.
