Acute food refusal in 12 year old with anorexia nervosa requiring sedation and mechanical ventilation for enteral feedings

ABSTRACT

Case Report Anorexia Nervosa is a mental health disorder with significant morbidity and mortality. Acute food refusal is one of the indications for admission. We present a patient who went to extreme lengths to restrict food intake, requiring intensive care sedation and ventilation to enable enteral feedings. 12 year old male, was admitted with symptoms of anorexia nervosa and BMI of 12.0, (<1%ile) with baseline BMI of 16 (25%ile), K of 3.3 and glucose of 54. He was treated with supervised eating on an inpatient pediatric floor with no need for enteral feeding. Psychiatry consultation confirmed the diagnosis of anorexia nervosa and recommended the addition of Olanzapine to his Sertraline. He was discharged pending placement in an eating disorder center after 21 days of hospitalization with discharge BMI of 14. He was followed as an outpatient by his pediatrician, dietician and counselor but unfortunately, he required readmission 11 days after discharge due to acute food refusal, with BMI that had dropped to 13.1. Patient was readmitted and started on nasogastric (NG) feeds but he became severely agitated, pulling NG out multiple times and continued to lose weight with BMI dropping to 12. Sedation was attempted to facilitate maintenance of NG feedings, with Benadryl, Haldol and Ativan, but was ineffective at levels deemed safe without compromising his airway and breathing. Due to severe malnourishment and unsuccessful NG feeds he was transferred to PICU for sedation, endotracheal intubation and continuous nasoduodenal (ND) tube feedings on two separate occasions while inpatient. He was able to wean from the ventilator but once awake he found ways to manipulate delivery of his calories, even finding scissors and cutting the ND tube. The patient ultimately agreed to eat in order to avoid replacement of the feeding tube. He was finally transferred to an eating disorder facility, with a BMI of 13.9 and persistent anorexia thinking with restriction of eating anything but pizza. Patient completed three months of an inpatient program and had significant improvement in BMI to 19.3 (70%ile). He was subsequently discharged for continued outpatient follow-up and since discharge from the eating disorder center, his BMI has shown steady improvement in outpatient follow-up. He shows no signs of food refusal and is doing well with Family Based Therapy. This case highlights several unique characteristics in management of eating disorder patients. The age and being male along with extreme food refusal and resistance to enteral feeding that led to the requirement of deep sedation are quite unusual and not well described in the medical literature. The severity of his illness was a significant barrier to inpatient placement. In addition, despite a nationwide attempt to find an inpatient facility for him, which took several weeks, we identified shortages in eating disorder beds that have been exacerbated by the COVID-19 pandemic.
