Vital Capacity Recruitment Maneuver


 A sigh maneuver, or a large tidal volume (Vt), has been suggested for reversing atelectasis; however, atelectasis is not uniformly reduced by a Vt increase or sigh up to airway pressure (Paw) of 20 cm H2O. 

 Instead, a PAW of 30 cm H2O is required for initial opening, and 40 cm H2O for more complete reversal. In the presence of normal lungs, such inflation is equivalent to a Vital Capacity (VC) and can therefore be called a VC maneuver (albeit achieved with positive PAW).

In addition, a significant hemodynamic effect is likely if the VC maneuver is sustained; in fact, inflation with a PAW of 40 cm H2O for 7 to 8 seconds appears to successfully open almost all anesthesia-induced atelectasis.

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:
