单剂量鼻内催产素预防创伤后应激障碍 (PTSD) 的功效
2010年2月7日 更新者：Sheba Medical Center
创伤事件后直接使用催产素预防创伤后应激障碍的疗效
本研究旨在检验以下假设，即在创伤后 6 小时内单次鼻内催产素给药有助于创伤的生理恢复，从而在事件发生后的几个月内预防创伤后应激障碍 (PTSD) 的发展。
在没有这种治疗的情况下（即在安慰剂条件下），我们假设更大比例的人会发展为 PTSD（即无法从急性影响中恢复）。
研究概览
详细说明
这是一项双盲、安慰剂对照试验，其中创伤受害者在遭受创伤后的前六个小时内被随机分配接受单次鼻内给药的催产素 (40IU) 或安慰剂。
为了提供治疗前基线，参与者将在治疗前接受医学和心理评估。
两周后，研究助理或研究精神病学家将进行行为评级并完成与 PTSD 风险因素有关的历史细节。
参与者将在第 1、3、6 和 13 个月时由研究精神病学家或研究助理再次评估。
符合条件的受试者将包括 18 岁以上的男性和女性，他们曾接触过符合 DSM-IV“A.1”创伤暴露标准的事件，并提供书面知情同意书以参与该研究。
为了招募更有可能患上 PTSD 的人，我们只会随机分配那些表现出明显焦虑、情绪困扰或分离的人，如视觉模拟量表所评估的那样。
将从到达 Chaim Sheba 医疗中心急诊室的创伤受害者中招募潜在参与者。
