Introduction to Ketamine Ketamine, a compound initially synthesized in 1962, marked a significant milestone in anesthetic medicine. Developed as an alternative to phencyclidine (PCP), ketamine was first used in clinical settings during the Vietnam War for its anesthetic properties. Over the years, its application has expanded beyond anesthesia, gaining attention for its potential in treating … Read more
Introduction Pre-anesthetic medications (premedicants) have been integral to anesthetic practice since the early days of surgical anesthesia. Their rational use is essential for improving patient comfort, reducing perioperative morbidity, minimizing anesthetic requirements, and managing surgery-related stress responses. These drugs are selected based on individual patient factors, surgical procedure, type of anesthesia planned, and institutional protocols. … Read more
Introduction Understanding Intravenous Anesthetics Intravenous anesthetics are a class of drugs used to induce and maintain anesthesia, administered directly into the bloodstream. They are essential for rapid induction of anesthesia, providing a controlled and reversible state of unconsciousness, making them indispensable in modern surgical practices. Significance in Anesthesia Practice Intravenous anesthetics play a pivotal role … Read more
Introduction Understanding General Anesthetics General anesthetics are a diverse group of drugs used to induce a reversible loss of consciousness, providing pain relief and muscle relaxation during surgical procedures. They play a critical role in modern medicine by allowing patients to undergo complex and potentially painful surgeries safely and comfortably. Role in Modern Surgery In … Read more
Introduction Inhalation anesthetics play a central role in modern anesthesia, enabling practitioners to achieve and maintain general anesthesia during surgical procedures. Unlike intravenous agents, which rapidly induce unconsciousness, inhalation anesthetics are administered via inhaled gases or vapors, typically using advanced anesthesia machines and vaporizers. These agents act on the central nervous system (CNS) to produce loss of consciousness, analgesia, and … Read more
Introduction Among the oldest and most widely used agents for hyperthyroidism, thionamides (alternatively โthioureasโ) remain essential in patient care. These medications include propylthiouracil (PTU), methimazole, and carbimazole, commonly referred to as antithyroid or thyroid-inhibiting drugs (Goodman & Gilman, 2018). Their core mechanism involves inhibiting the synthesis of thyroid hormones, thus reducing circulating levels of T3 (triiodothyronine) and T4 (thyroxine). Whether prescribed to stabilize newly diagnosed Gravesโ disease, manage toxic nodular goiter, … Read more
