Swallowing disorders in severe brain injury: Risk factors affecting return to oral intake

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.

A new cervical spine clearance protocol using computed tomography.

OBJECTIVE The purpose of this study was to assess a cervical spine clearance protocol for blunt trauma patients using helical computed tomographic (CT) scan of the cervical spine (C-spine). METHODS A protocol using CT scan of the C-spine was implemented and the first 6 months of use reviewed. Patients requiring a CT scan of the head had the C-spine evaluated by lateral C-spine radiography and a helical CT scan. Patients without indication for CT scan of the head had the C-spine evaluated by three-view radiography (anteroposterior, lateral, and odontoid) with selective CT scan of the C-spine for imaging areas not well visualized or those with abnormalities identified by radiography or by clinical examination alone. RESULTS Three hundred twenty-four patients were admitted to the trauma center after blunt trauma during the first 6 months of protocol implementation. Head CT scans were obtained in 158 patients and lateral cervical spine radiography in conjunction with helical CT scanning evaluated the C-spine. The other 166 patients had the cervical spine cleared by three-view radiography series or by clinical examination alone. For patients in whom a head CT scan was not indicated, CT scanning was used only when plain radiographs failed to adequately visualize the entire C-spine. A total of 15 injuries (4.6% of the group) were detected. Seven injuries were suspected or detected by lateral plain radiographs and confirmed by CT scan. Six patients had an injury not detected by radiography but diagnosed by CT scan, and one patient had a false-positive radiograph. Of the remaining two injuries, one was diagnosed by magnetic resonance imaging and the other by CT scan outside of the protocol. Lateral plain radiographs alone failed to detect 46% (n = 6) of all injuries. CONCLUSION In our series, the selective use of helical CT scanning with plain radiography increased the accuracy with which cervical spine injury was detected from 54% to 100%. The protocol allowed for more rapid evaluation in many patients as well. We recommend that practice guidelines include the use of helical CT scan of the entire C-spine as the diagnostic procedure for those blunt trauma patients undergoing CT scanning of the head.

Factors Affecting Oral Feeding with Severe Traumatic Brain Injury

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.

Causes and complications associated with swallowing disorders in traumatic brain injury.

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.

Significance of Scapular Fracture in the Blunt-Trauma Patient?☆☆☆★

STUDY OBJECTIVE To determine the significance of scapular fractures in blunt-trauma patients compared with blunt-trauma patients without scapular fractures. DESIGN Retrospective chart review of 11,500 blunt-trauma patients with a control group matched for age, sex, and mechanism of injury. SETTING Two Level I trauma centers. PARTICIPANTS Ninety-two blunt-trauma patients with scapular fractures and 81 control patients. RESULTS Mortality, neurovascular injury, and injury severity scores were compared for blunt-trauma patients with scapular fractures with those of the control group. Analysis revealed a 1% incidence of scapular fractures in blunt trauma with no neurovascular injury and no mortality. Scapular fractures were associated with thoracic injury in 49% of the patients, compared with 6% in the control group (difference, 43%; 95% confidence interval, 31.6 to 51.4; P < .001, Fishers exact test). CONCLUSION Scapular fractures are not a significant marker of greater mortality or of neurovascular morbidity in blunt-trauma patients.

Post-appendectomy visits to the emergency department within the global period: a target for cost containment.

BACKGROUND Postoperative visits to the emergency department (ED) instead of the surgeons office consume enormous cost. HYPOTHESIS Postoperative ED visits can be avoided. SETTING Fully accredited, single-institution, 617-bed hospital affiliated with the University of Connecticut School of Medicine. PATIENTS Retrospective analysis of 597 consecutive patients with appendectomies over a 4-year period. METHODS Demographic and medical data, at initial presentation, surgery, and ED visit were recorded as categorical variables and statistically analyzed (Pearson chi(2) test, Fisher exact test, and linear-by-linear). Costs were calculated from the hospitals billing department. RESULTS Forty-six patients returned to the ED within the global period with pain (n = 22, 48%), wound-related issues (n = 6, 13%), weakness (n = 4, 9%), fever (13%), and nausea and vomiting (n = 3, 6%). Thirteen patients (28%) required readmission. Predictive factors for ED visit postoperatively were perforated appendicitis (2-fold increase over uncomplicated appendicitis) and comorbidities (cardiovascular or diabetes). The cost of investigations during ED visits was

55,000 plus physician services. CONCLUSIONS ED visits during the postoperative global period are avoidable by identifying patients who may need additional care; improving patient education, optimizing pain control, and improving patient office access.
