Background: The incidence of sevoflurane-related adverse respiratory events in children with asthma is notably high. During different phases of sevoflurane anesthesia, asthmatic children's airways are exposed to varying concentrations of the anesthetic. However, the specific effects of different concentrations of sevoflurane on the developing airways with asthmatic hyperreactivity have not been systematically studied.

Mechanism exploration involves anesthesia and surgery that lead to microglial activation, promote the synthesis and secretion of inflammatory factors, cause an inflammatory cascade, aggravate nerve cell damage, and lead to cognitive dysfunction. It is believed that microglia-mediated neuroinflammatory responses play a vital role in the formation of PND.

In this editorial, we provide a critical review of the article by Tang published in the , focusing on the utilization of butorphanol for epidural analgesia during labor. Our discussion encompasses recent research developments in epidural labor analgesia, specifically highlighting the current status of clinical applications of butorphanol and associated treatment approaches. Epidural analgesia is widely acknowledged as the primary method for pain management during labor, offering effective and prolonged pain relief while allowing mothers to remain alert and actively participate in the delivery process.

There is a high anticipation for creating materials that maintain prolonged effectiveness of local anesthetics through a straightforward administration technique. Chitosan is the most typical natural amino polymer, which is highly reactive and easy to modify.

However, recent research suggests that general anesthesia may be associated with the occurrence of perioperative neurocognitive disorder (PND). PND is characterized by a decline in cognitive function after surgery, including impairments in attention, memory, learning, and executive functions.

Methods: Sixty-six C57BL/6J mice were used in the experiment model and were randomly divided into the sevoflurane group and the control group. The mice in the sevoflurane group were anesthetised with 3.
Neurodegenerative diseases (NDs), such as Alzheimer's disease, Parkinson's disease, Huntington's disease, and motor neuron disease, are diseases characterized by neuronal damage and dysfunction. NDs are considered to be a multifactorial disease with diverse etiologies (immune, inflammatory, aging, genetic, etc.) and complex pathophysiological processes.

Sixty patients who fulfilled the inclusion and exclusion criteria of this study were selected. Sufentanil was administered intravenously and remimazolam besylate was administered 2 min later.

The present study was designed to explore the influences of different dosages of S-ketamine anesthesia induction regimes on psychiatric complications and postoperative prognosis in patients undergoing gynecological operations. In this prospective, triple-blinded, randomized, controlled study, patients undergoing elective gynecological surgery were randomized to one of three treatment groups: low-dose S-ketamine (LDSK) group (a 0.

Methods: Forty-eight patients aged 18-64 years old were randomized to receive adamgammadex (2, 4, 6, and 8 mg.kg ) or placebo at a ratio of 10:2 for reversal of 0.
Esketamine is dextrorotatory ketamine, which is an enantiomer of ketamine. Compared with ketamine, it has the advantages of a fast metabolism, fewer side effects, and strong pharmacological effects, so it is more suitable for clinical use. Esketamine has a powerful analgesic effect and has little effect on breathing.

This disease is associated with multiple factors, such as chronic brain injury, aging, chronic systemic disease, mental state, and psychological factors. However, the pathological mechanism of CI remains unclear; it is usually associated with such underlying diseases as diabetes and hyperlipidemia.

This study aimed to explore the role of improved combined analgesia methods in pain, sedation, postoperative nausea, and vomiting (PONV) in patients undergoing gynecological surgeries. This study was a prospective, randomized, double-blind controlled study.

Based on this, we reviewed and summarized the literature on peripheral trunk nerve block include: paraspinal block, retrolaminar block, plane block of erect spinal muscle, transverse convex to pleural midpoint block, block of the trapezius muscle and anterior serratus muscle, anterior serratus muscle block, thoracic nerve block, abdominal transverse fascia block, type-I block of quadratus lumborum, type-II block of quadratus lumborum, type-III block of quadratus lumborum, block of the sheath of rectus abdominis. This paper reviews the ultrasound-guided peripheral trunk block technique, including development history, anatomic basis, implementation methods, advantages and disadvantages of nerve block technique, and describes the bottleneck and difficulties of nerve block technique at present.
