TBI, traumatic brain injuries, TBIs
It is indisputable that traumatic brain injuries (TBIs) are among the primary factors contributing to fatalities and impairments worldwide.The initial discovery of ischemic preconditioning (IPC) was made by Murry et al in 1986,Nevertheless, due to the distinctive characteristics of individuals with TBI and the absence of medical research supported by substantial sample sizes, the effectiveness of RIPC remains uncertain. Therefore, the current investigation aimed to examine the theory that the application of preoperative RIPC could enhance the outcomes in patients with severe TBI.
