Active process during or after anesthesia that is usually accompanied by retching; common in brachycephalic dogs or nonfasted patients. Which term describes this?

• A. Vomiting
• B. Regurgitation
• C. Aspiration
• D. Nausea

Answer: (A)

Vomiting is an active process in which coordinated contractions of the abdominal muscles and diaphragm, along with glottic closure, propel gastric contents upward and out of the mouth, usually after a retching phase. During anesthesia, this reflex can be triggered, and it’s more likely in brachycephalic dogs or in nonfasted patients who have gastric contents ready to be expelled. The key clue is the retching that typically accompanies vomiting, distinguishing it from regurgitation, which is a passive flow of contents into the mouth without the forceful abdominal effort or retching. Aspiration refers to inhaling those contents into the lungs, a potential complication if vomiting occurs during anesthesia. Nausea is the sensation that precedes vomiting, not the actual expulsion. So the described active process with retching is vomiting.
