Therapeutic hypothermia may need prolonged duration for the patients with severe traumatic brain injury (sTBI).
The Long-Term Hypothermia trial was a prospective, multicenter, randomized, controlled clinical trial to examine the safety and efficacy in adults with sTBI. Eligible patients were 18-65, Glasgow Coma Scale score at 4 to 8, and initial intracranial pressure (ICP) ≥ 25 mm Hg, randomly assigned to the long-term mild hypothermia group (34-35 °C for 5 days) or normothermia group at 37 °C. The primary outcome was the Glasgow outcome scale (GOS) at 6 months. Secondary outcomes included ICP control, complications and laboratory findings, the length of ICU and hospital stay, and GOS at 6 months in patients with initial ICP ≥ 30 mm Hg. This trial is registered with ClinicalTrials.gov, NCT01886222.
302 patients were enrolled from June 25, 2013, to December 31, 2018, with 6 months follow-up in 14 hospitals, 156 in hypothermia group and 146 in normothermia group. There was no difference in favorable outcome (OR 1·55, 95%CI 0·91-2·64; = 0·105) and in mortality ( = 0·111) between groups. In patients with an initial ICP ≥ 30 mm Hg, hypothermic treatment significantly increased favorable outcome over normothermia group (60·82%, 42·71%, respectively; OR 1·861, 95%CI 1·031-3·361; = 0·039). Long-term mild hypothermia did not increase the incidences of complications.
Long-term mild hypothermia did not improve the neurological outcomes. However, it may be a potential option in sTBI patients with initial ICP ≥ 30 mm Hg.

对于重度创伤性脑损伤（sTBI）患者，治疗性低温可能需要持续较长时间。
长期低温试验是一项前瞻性、多中心、随机对照临床试验，旨在研究其对成年sTBI患者的安全性和有效性。符合条件的患者年龄在18至65岁之间，格拉斯哥昏迷量表评分为4至8分，初始颅内压（ICP）≥25毫米汞柱，随机分为长期轻度低温组（34 - 35°C，持续5天）或37°C的正常体温组。主要结局指标是6个月时的格拉斯哥预后量表（GOS）。次要结局指标包括ICP控制情况、并发症和实验室检查结果、重症监护病房（ICU）和住院时间，以及初始ICP≥30毫米汞柱患者6个月时的GOS。该试验已在ClinicalTrials.gov注册，注册号为NCT01886222。
2013年6月25日至2018年12月31日共纳入302例患者，在14家医院进行了6个月的随访，低温组156例，正常体温组146例。两组在良好结局（比值比1.55，95%置信区间0.91 - 2.64；P = 0. 105）和死亡率（P = 0.111）方面无差异。在初始ICP≥30毫米汞柱的患者中，低温治疗组的良好结局显著高于正常体温组（分别为60.82%和42.71%；比值比1.861，95%置信区间1.031 - 3.361；P = 0.039）。长期轻度低温并未增加并发症的发生率。
长期轻度低温并未改善神经学结局。然而，对于初始ICP≥30毫米汞柱的sTBI患者，它可能是一个潜在的选择。
