Here are some common causes and management strategies for delayed discharge from the PACU: Causes of Delayed Discharge: 1. Persistent Respiratory Issues: If a patient is experiencing respiratory complications, such as low oxygen saturation or difficulty breathing, they may require additional time in the PACU. 2. Hemodynamic Instability: Patients with unstable blood pressure, heart rate, … Read more

Liquid oxygen (LOX) plays a vital role in the field of anesthesia, ensuring the safety and success of surgical procedures. This content will explore the use of LOX in anesthesia, its properties, and its significance in maintaining patient well-being during surgery. I. Properties of Liquid Oxygen: – Liquid oxygen is a cryogenic liquid, which means … Read more

Introduction Cerebral autoregulation is a vital mechanism that ensures a stable blood supply to the brain, irrespective of changes in systemic blood pressure. As an anesthesiologist, understanding cerebral autoregulation is crucial for managing patients undergoing various surgical procedures, especially those involving the central nervous system. This article explores the factors influencing cerebral autoregulation in both … Read more

Several scoring systems are used in neurosurgical patients to assess various aspects of their condition, predict outcomes, and guide treatment decisions. Here are some commonly used scoring systems in neurosurgery: 1. Glasgow Coma Scale (GCS): The GCS assesses a patient’s level of consciousness based on eye, verbal, and motor responses. It is widely used to … Read more

Stereotactic Electroencephalography (SEEG) is an invasive method used to monitor and localize seizure foci in drug-resistant focal epilepsies. It involves the implantation of leads to record seizures and achieve three-dimensional analysis of the epileptogenic zone. The history of SEEG dates back to the 19th century, with advancements in understanding the electrical activity of nerves, muscles, … Read more

Anesthesia pharmacology and neurophysiological monitoring are closely intertwined in surgeries involving the nervous system. The choice of anesthetic agents and their management significantly impacts the quality and reliability of neurophysiological monitoring. Here are key considerations regarding anesthesia pharmacology in the context of neurophysiological monitoring: Anesthetic Agents Selection: The selection of anesthetic agents is critical. Anesthetics … Read more

Introduction:  Electroconvulsive Therapy (ECT) is a therapeutic procedure primarily used for patients with pharmacotherapy-resistant psychiatric disorders, most notably depression. This treatment modality, introduced in the 1930s, involves inducing a controlled seizure through electrical stimulation of the brain while the patient is under general anesthesia. ECT aims to provide hemodynamic stability, induce amnesia, and achieve muscle … Read more

SECTION 1   History: Awake craniotomy has historical roots in ancient trepanation for various purposes, including epilepsy treatment. Modern AC began with Sir Victor Horsley in 1886 and was further developed by Wilder Penfield in the 20th century. Indications: Brain Tumor Resection: Awake craniotomy is commonly used for removing brain tumors located near eloquent areas, … Read more

IntroductionWithin the intricate landscape of anesthesia pharmacology, a central player emerges—gamma-aminobutyric acid (GABA). GABA, a neurotransmitter, and its receptors stand as pivotal elements orchestrating the balance between sedation, unconsciousness, and analgesia. In this article, we delve into the crucial role of GABA receptors, categorizing them into their distinct types and parts, within the realm of … Read more

Introduction:Postoperative blurring of vision, also known as transient postoperative visual loss (POVL), can occur following nonocular surgeries, such as cardiac, spinal, or vascular procedures. Understanding the mechanisms, potential causes, risk factors, and preventive strategies is crucial for both patients and healthcare providers. Mechanisms:The exact mechanisms leading to POVL are multifactorial and may involve: Ischemic Optic … Read more
