Oxygen delivery and consumption calculations

Oxygen delivery and consumption calculations should be utilised to evaluate and optimize gas exchange:
  • Oxygen Delivery: DO2 = 10 x CI x CaO2
  • Oxygen Consumption: VO2 = 10 x CI x (CaO2 — CvO2)
Where:
CaO2 (arterial oxygen content) = (Hb x 1.36 x SaO2) + (0.0031 x PaO2), 
and 
CvO2 (mixed venous oxygen content) = (Hb x 1.36 x SvO2) + (0.0031 x PvO2)
CI = cardiac index
HB = hemoglobin
SaO2 = arterial oxygen saturation
PaO2 = partial pressure of oxygen in arterial blood
SvO2 = venous oxygen saturation
PvO2 = partial pressure of oxygen in venous blood

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:
