Excessive anesthesia in cats can cause many adverse reactions, such as cardiac arrest, bradycardia, arrhythmia, insufficient ventilation, hypoxemia, hypotension and hypertension.

Drug overdose, wrong administration time, respiratory failure, abnormal body temperature, metabolic disorder such as hypoglycemia, severe hyperglycemia, electrolyte disorder, acidosis, etc. Will cause a delay in awakening, which will seriously lead to the death of the cat.

Anesthesia is the most important part in the operation, and most cats and dogs who died in the operation have complications of anesthesia. The most common complications are respiratory and heart rate arrest, blood pressure drop and pulmonary edema. Most of them occur at the beginning of anesthesia and when animals wake up. Anesthesia complications when animals wake up from anesthesia are often easily overlooked.
