UPTAKE AND DISTRIBUTION OF VOLATILE ANESTHETICS




UPTAKE AND DISTRIBUTION OF VOLATILE ANESTHETICS


  • Vessel-rich organs: brain, heart, liver, kidneys, endocrine system; 10% of the body weight; receive 75% of the cardiac output ; small volume; moderate solubility; rapid saturation
  • Muscle group : 50% of body weight; receives 20% of the cardiac output; continued uptake as a result of greater volume ; uptake can last for hours


  • Fat group : 20% of total body weight; receives 6% of cardiac output; high solubility for anesthetic agent so can have sustained uptake for days


  • Vessel-poor group : 20% of body weight; minimal cardiac output; uptake is insignifi cant

Ketamine: The Past, Present, and Potential Future of an Anesthetic Drug

Ketamine is a powerful anesthetic drug that has been used in medical settings for decades. However, its effects on the brain have also led to its use as a recreational drug, leading to controversy surrounding its use. Despite its negative associations, recent research has shown promising potential for the drug in the treatment of mental health conditions such as depression and post-traumatic stress disorder (PTSD).

Fast track anesthesia approaches

  Fast track anesthesia schemes are multi-modal approaches that aim to reduce the physiological stress response to surgery, enhance recovery, and improve patient outcomes. These schemes typically involve several aspects of perioperative care, including anesthesia management, surgical technique, pain management, fluid management, and early mobilization. Here are some common fast track anesthesia schemes:
