Progesterone has been shown to have neuroprotective effects in multiple animal models of brain injury, whereas the efficacy and safety in patients with traumatic brain injury (TBI) remains contentious. Here, a total of seven randomized controlled trials (RCTs) with 2492 participants were included to perform this meta-analysis. Compared with placebo, there was no significant decrease to be found in the rate of death or vegetative state for patients with acute TBI (RR = 0.88, 95%CI = 0.70, 1.09, p = 0.24). Furthermore, progesterone was not associated with good recovery in comparison with placebo (RR = 1.00, 95%CI = 0.88, 1.14, p = 0.95). Together, our study suggested that progesterone did not improve outcomes over placebo in the treatment of acute TBI.
已证实孕酮在多种脑损伤动物模型中具有神经保护作用，而其在创伤性脑损伤（TBI）患者中的疗效和安全性仍存在争议。在此，共纳入7项随机对照试验（RCT），涉及2492名参与者，以进行此项荟萃分析。与安慰剂相比，急性TBI患者的死亡率或植物状态发生率没有显著降低（RR = 0.88，95%CI = 0.70，1.09，p = 0.24）。此外，与安慰剂相比，孕酮与良好恢复无关（RR = 1.00，95%CI = 0.88，1.14，p = 0.95）。总之，我们的研究表明，在急性TBI治疗中，孕酮并不比安慰剂更能改善预后。
