Ketamine: Bradycardia, cardiac arrest and small operation at the rectum due to anaesthetic and surgical complications.

In a study of 200 pediatric patients, it was found that some patients experienced bradycardia, cardiac arrest, or complications during surgery due to the use of ketamine anesthesia. The specific details of the patients' ages, genders, and treatment regimens were not provided. One patient developed bradycardia, another experienced cardiac arrest in the recovery room, and a third patient required a small operation at the rectum due to complications. Unfortunately, the patient who underwent the rectal operation died after being intubated. [Extracted from the article]
