You will be shown an abstract from a biomedical research paper. Given this abstract, your task is to extract all unique entities of the following types: ["Disease", "Chemical"].

Please return the output as a JSON object of the format: {"Chemical" : ["Naloxone", ...], "Disease" : ["Hypotensive", ...]}. The keys should be entity types and values should be lists of extracted entities belonging to the corresponding type. If you cannot find entities belonging to a specific type, the value should be [].

Only output the JSON object and do not include any additional text.

Abstract:

Cardiac arrest in a child with cerebral palsy undergoing sevoflurane induction of anesthesia after preoperative clonidine. Clonidine is a frequently administered alpha2-adrenergic agonist which can decrease heart rate and blood pressure. We present a case of a 5-year-old child with cerebral palsy and seizure disorder, receiving clonidine for restlessness, who presented for placement of a baclofen pump. Without the knowledge of the medical personnel, the patient's mother administered three doses of clonidine during the evening before and morning of surgery to reduce anxiety. During induction of anesthesia, the patient developed bradycardia and hypotension requiring cardiac resuscitation. There are no previous reports of clonidine-associated cardiac arrest in a child undergoing induction of anesthesia.
