    The immunosuppressive effects on cell-mediated immunity of alfathesin, when used as the sole agent for short-term anaesthesia, were investigated in ten women undergoing pregnancy termination. Cell-mediated immunity was evaluated by E rosette formation in peripheral blood (reflecting the percentage of T lymphocytes) and by proliferative responses to the mitogens concanavalin A and phyto-haemagglutinin in various concentrations. Measurements were made before alfathesin was administered, and again after 60 minutes, two days and seven days. Significant reductions in the percentage of E rosettes in peripheral blood and in mitogenic responses to concanavalin A were observed 60 minutes after administration of alfathesin. A model is proposed in which alfathesin binds to lymphocytic membrane receptors, thus affecting in vitro cell-mediated immune reactions.

    Local Anesthetics: Clinical Application as Surface, Infiltration, and Conduction Block Anesthesia

    Depending on the target organ, local anesthetics (LAs) can be administered via various routes. In surface anesthesia, LAs are applied directly to the surface of the skin or mucous membranes. It is widely used for topical skin numbing before venipuncture or minor surgical procedures. Commonly used surface local anesthetics are lidocaine or benzocaine sprays or creams. Surface anesthesia occurs within 5 minutes and lasts for about 60 minutes. One of the main disadvantages of topical anesthesia is...

    General Anesthesia: Overview

    Anesthesia is a medical procedure that uses drugs for CNS suppression to enable painless surgeries and procedures. The selection of anesthetics is influenced by their pharmacokinetic properties, side effects, and patient characteristics. Various types of anesthesia include general, local, regional, spinal, and inhalational.
    General anesthesia induces unconsciousness in the whole body, while the others target specific areas or sensations. It is administered to minimize adverse effects, maintain...

    Parenteral Anesthetics: Overview

    Intravenous anesthetics are drugs administered parenterally to induce anesthesia or sedation. Propofol is a widely used agent formulated as a 1% emulsion in soybean oil, glycerol, and egg phosphatide. It induces rapid anesthesia primarily due to its rapid distribution from the bloodstream to target tissues and is metabolized in the liver. However, it can cause significant pain on injection and hypertriglyceridemia. Fospropofol, a water-based prodrug of propofol, lacks these adverse effects.

    Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living donor...
