Severe traumatic brain injury is associated with both acute and delayed neuro- logical injury. Cerebral vasospasm is commonly associated with delayed neurological decline in aneurysmal subarachnoid hemorrhage patients. However, the role played by vasospasm in traumatic brain injury is less clear. ⋯ We present a patient with a severe traumatic brain injury who had dramatic improvement following emergent decompressive hemicraniectomy. Two weeks after initial presentation he suffered a precipitous decline despite intensive surveillance. This case illustrates the distinct challenges of diagnosing cerebral vasospasm in the setting of severe traumatic brain injury.

Observational Study[Pain assessment of tracheal suctioning on brain injury patients by pain behavioral indicator scale (ESCID)].
To assess pain response on patients with moderate to severe head injury before a common nursing procedure: tracheal suctioning. ⋯ Pain was assessed on 27 patients. 82% suffered from severe head trauma and 18% moderate. The average pain value during nursing procedure day 1 was 3, 18±2.6, day 3: 2, 59±2 and day 6: 3, 94±2.3. There was a significant increase in mean pain while performing suctioning during the three days of assessment (P<.05); however no significant differences between the average pain value on the three days of the assessment (P>.05) were shown. Data for the painless procedure were significantly different on day 6 (P<.05) CONCLUSION: During tracheal suctioning in patients with head injury in the first 6 days in the ICU, objective mild-moderate pain according to ESCID scale has been detected.

Willingness to favor aggressive care and live with disability following severe traumatic brain injury: a survey of healthy young adults in Hawai'i.
Traumatic brain injury (TBI) is a major public health problem that significantly impacts young adults. Since severe TBI patients lack decision-making capacity, the providers and patient surrogates are often faced with the challenging task of deciding whether to continue with aggressive life-prolonging care or to transition to comfort-focused care with an expected outcome of natural death. The assumption is often made that aggressive care is appropriate for young patients who suffer severe TBI despite the high likelihood of a poor outcome. ⋯ Despite being presented with a high likelihood of long-term moderately severe-to-severe disability, 65 of the 115 respondents (57%) favored aggressive care. A willingness to live with receptive aphasia was the only independent factor that predicted aggressive care (OR 2.50, 95% CI: 1.15 to 5.46). Even among the young adults, preference of care was divided between aggressive and conservative approaches when presented with a hypothetical case of severe TBI.

Blast-induced tinnitus, along with associated auditory impairment and traumatic brain injury, is a primary concern facing military service members. To search for treatment, we investigated the therapeutic effects of sildenafil, a phosphodiesterase-5 inhibitor, given its vasodilatory effects and evidence suggesting its beneficial effects on noise-induced hearing loss. Rats were subjected to three consecutive blast exposures at 22 psi and were monitored for tinnitus using a gap-detection acoustic startle reflex paradigm. ⋯ Complex results were observed in the startle force data, where sildenafil-treated rats displayed significantly reduced startle force compared to the untreated blasted group, suggesting possible mitigation of traumatic brain injury and suppression of hyperacusis-like percepts. Taken together, sildenafil showed a therapeutic effect on blast-induced tinnitus and audiological impairment in a time-dependent manner. Other regimens such as higher dosage prior to blast exposure and combination with other treatments deserve further investigation to optimize the therapeutic effects.
