Reflex and Spontaneous Movements in Pediatric Patients with Brain Death

Reflex and spontaneous movements are not uncommon in brain death patients. However, most studies have been conducted in adults, while reports in infants and children are rare. Thus, we aimed to evaluate the frequency and characteristics of these movements in pediatric patients declared as brain death.

Records of pediatric patients who were diagnosed as brain death from 15 hospitals in the Yeongnam region, South Korea, between January 2013 and September 2016 were analyzed. All body movements in patients who met the criteria for brain death as established by the Korea Medical Association were assessed by medical doctors and trained organ transplant coordinators. The frequency and characteristics of these movements were identified. Additionally, the demographic and clinical factors of the brain death patients with and without these movements were compared.

A total of 31 patients who met the criteria for brain death were enrolled. Seven patients (22.6%) showed either reflex or spontaneous movements; six of them (85.7%) showed reflex movements only, and one patient (14.3%) showed both types of movements. The most common types of reflex movements were the flexor/extensor plantar response and isolated finger jerk. Four of seven patients (57.1%) showed a single movement pattern, while three (42.9%) showed two different movement patterns.

It is essential for physicians who perform pediatric brain death examinations to recognize the frequency and characteristics of reflex and spontaneous movements, and this article may help in the accurate and prompt diagnosis of brain death.
