- Abstract
Background: In chimpanzees (Pan troglodytes) the most common risk factors associated with anaesthesia are the age of the animal, health status, body condition and procedural urgency. Co-existing disease processes, including obesity, can also put the animal at a higher anaesthesia-related risk. Out of these, cardiac risk factors are the most studied, while comparatively less is known about respiratory risks. Objectives: In this case report we describe an acute upper respiratory airway obstruction in a female chimpanzee, primarily caused by obesity and leading to fatal consequences despite the emergency treatments carried out. Materials and Methods: A 39.5-year-old, clinically healthy, but severely overweight (body condition score 9/9, estimated body weight 70 kg, actual body weight 82 kg) female chimpanzee was anaesthetised for routine health check and enclosure move. The animal was given oral midazolam premedication (0.43 mg/bwkg), then induced with tiletamin-zolazepam (1.7 mg/kg) and medetomidine (0.017 mg/kg) via im. hand injection. Results and Discussion: Respiratory arrest was experienced shortly after induction. Intubation was proved to be difficult due to the excess laryngeal tissue and positioning difficulties, due to the severe obesity of the animal. Cardiopulmonary resuscitation (CPR) was provided but was ultimately unsuccessful and the animal died under anaesthesia. A full post mortem examination revealed previously undiagnosed idiopathic myocardial fibrosis and subclinical heart failure, a well-demarcated intraabdominal abscess adhered to the ventral aspect of the uterus, as well as severe obesity without further relevant organ damage. There were no anatomical or pathophysiological changes noted in the upper airways. In summary the upper airway obstruction, which ultimately led to the death of the animal, was caused by severe obesity, difficulty in securing an airway under anaesthesia and the consequential hypoxia, which was likely compounded by the previously undiagnosed subclinical heart failure. The authors highlight the risk of obesity in chimpanzee anaesthesia and how this can affect securing an airway.
