Effect of Dexmedotomdine hydrochloride (Percedex & REG;) on functional outcome of patients with moderate and severe traumatic brain injury

Traumatic brain injury (TBI) is considered among the leading causes of morbidity and mortality worldwide being associated with significant social and economic burden. The best sedative regimen in TBI patients is yet to be identified. This study was designed to determine the effects of dexmedotomdine hydrochloride (Percedex (R), DEX) on functional outcome of patients with moderate and severe traumatic brain injury (TBI). This was a retrospective cohort study including patients with severe (3-8) and moderate (9-13) TBI referring to a level I trauma center. We studied two groups of patients, those receiving DEX or routine sedation regimen in neurointensive care unit (NICU). The main outcome measures were the Glasgow outcome scale extended (GOSE) at 3 and 6month. We have also recorded ICU and hospital length of stay (LOS) and the tracheostomy rate. We included 138 patients in two study groups (each including 69). The baseline characteristics were comparable between groups. DEX was associated with lower LOS in hospital (p = 0.002) and NICU (p = 0.003). The GOSE was comparable between two study groups at 3 (p = 0.245) and 6-month (p = 0.497). Multivariate regression analysis revealed that after LOS of NICU and hospital stay adjustment, DEX group experienced significantly improved 6month GOSE with the average improvement in score of 0.92 compared to the control group (p = 0.041). DEX administration in patients with moderate and severe TBI was associated with decreased NICU and hospital LOS and improved functional outcome at 6-month.

Automated summary

This study examined the effects of Dexmedotomdine hydrochloride (Percedex(R), DEX) on functional outcome of patients with moderate and severe traumatic brain injury (TBI). The results showed that DEX administration was associated with decreased hospital stay and improved functional outcome at 6-months.
