How is ketamine used as an anesthetic in surgery?
Ketamine’s role as an anesthetic is multifaceted:
- Dissociative Anesthesia: Ketamine’s unique characteristic is its ability to induce a state of dissociative anesthesia. During this state, patients appear awake but are disconnected from their surroundings, making it an ideal choice for various surgeries. Patients do not feel pain or have awareness, which is invaluable for both minor and major procedures.
- Preservation of Respiratory Function: Unlike some other anesthetics, ketamine has minimal impact on respiratory function. This property is crucial in surgeries where maintaining airway reflexes and breathing is essential. It ensures that patients continue to breathe effectively during the procedure.
- Resource-Limited Settings: Ketamine’s versatility makes it a valuable option in resource-limited settings or when traditional anesthetics are unavailable. It can be administered in a wide range of healthcare settings, making it a critical tool in global healthcare.
What is ketamine’s role in emergency medicine, and in what situations is it administered?
Ketamine’s role in emergency medicine extends to various critical situations:
