What type of surgery requires the use of general anesthesia?

• A. Minor skin lesions
• B. Extensive orthopedic surgery
• C. Dental cleanings
• D. Routine vaccinations

Answer: (B)

Extensive orthopedic surgery necessitates the use of general anesthesia because it typically involves significant manipulation of bones and joints, which can cause considerable pain and discomfort. General anesthesia induces a state of unconsciousness and provides the analgesia necessary for these invasive procedures, ensuring that the animal remains still and pain-free throughout the surgery.

In contrast, minor skin lesions, dental cleanings, and routine vaccinations are generally classified as less invasive procedures, often manageable under local anesthesia or sedation without the need for full general anesthesia. These procedures do not typically require the depth of anesthesia provided by general methods, as the surgical interventions involved are limited in terms of tissue trauma and pain. Therefore, extensive orthopedic surgery stands out as the option that mandatorily requires general anesthesia to ensure the safety and comfort of the animal during the procedure.
