RESUMEN
OBJECTIVE: To determine the incidence and type of swallowing disorders that accompany severe brain injury and to identify factors that affect oral intake. DESIGN: Inception cohort study. SETTING: Level I trauma center. PATIENTS: Consecutively admitted patients with severe brain injury who achieved cognitive levels during admission to assess swallowing and who did not sustain injuries preventing swallowing assessment (n = 54). MAIN OUTCOME MEASURES: Type of swallowing abnormalities and presence of aspiration evident on videofluoroscopic swallow studies (VFSS), days to initiation and achievement of oral feeding, ventilation days, presence of a tracheostomy, and cognitive levels at initiation and achievement of oral feeding. RESULTS: Sixty-one percent of subjects exhibited abnormal swallowing. Loss of bolus control and reduced lingual control occurred most commonly. Aspiration rate was 41%. Normal swallowers achieved oral feeding in 19 days versus 57 days for abnormal swallowers. Rancho Los Amigos (RLA) Level IV was needed for initiation of oral feeding; Level VI was needed for total oral feeding. Risk factors for abnormal swallowing included: lower admission Glasgow Coma Scale (GCS) and RLA scores, presence of a tracheostomy, and ventilation time longer than 2 weeks. Risk factors for aspiration were lower admission GCS and RLA scores. CONCLUSIONS: Swallowing disorders and behavioral/cognitive skills are frequently present in patients with severe brain injury and significantly affect oral intake of food. Persons who swallow abnormally take significantly longer to start eating and to achieve total oral feeding, and they require nonoral supplementation three to four times longer than those who swallow normally.

Safe and adequate nutrition, vital to the recovery from a traumatic brain injury, can be severely compromised by the presence of dysphagia. This study identified injury severity and swallowing factors that were associated with impaired oral intake in patients with severe brain injury. An admitting Glasgow Coma Scale (GSC) 3-5; a Rancho Los Amigos Scale of Cognitive Functioning (RLA) Level II; a computed tomography (CT) scan exhibiting midline shift, brainstem involvement, or brain pathology requiring emergent operative procedures; or ventilation time >/=15 days identified patients at highest risk for abnormal swallowing, aspiration, and delay in initiation of oral feeding and achievement of total oral feeding. When combined in multivariate models, RLA Level, CT scan, ventilation time and aspiration emerged as significant independent predictors of impaired oral intake.

A major complication commonly seen in persons with severe brain injury is swallowing dysfunction. The neuropathology leading to impaired swallowing is discussed. In addition, Other risk factors associated with dysfunctional swallowing, such as tracheostomy and the need for prolonged ventilatory support, are discussed. Within the intensive care environment, the consequences of impaired swallowing leading to aspiration-a major cause of pneumonia-are discussed.

With traumatic brain injuries numbering more than two million per year, health professionals are faced with the challenges of restoring and maximizing quality of life. This study quantifies the benefits of a formalized head injury program, including the concept of trauma rehabilitation, defined as early, aggressive rehabilitation during acute hospitalization. Thirty-eight severely head injured patients received treatment at the same rehabilitation facility. Twenty-one of these patients received acute care services at ten different hospitals without formalized traumatic brain injury programs, and 17 received services at a hospital with a formalized early intervention program. Comparison of outcome data for the two programs revealed that patients in the formalized program had comas and rehabilitation stays approximately one third the length of patients in nonformalized programs (18.9 vs 53.8 days and 106.5 vs 239.5 days, respectively). Mean cognitive levels at discharge from the acute hospitals (5.6 vs 4.0) and the rehabilitation facility (7.4 vs 6.7) were significantly higher for the formalized program, and they facilitated a significantly higher percentage of discharges to home vs extended care facility (94% vs 57%).
