据美联社报道，田纳西州死囚克里斯塔·盖尔·派克（Christa Gail Pike）在两次注射致死剂量的戊巴比妥后均幸存下来，这一备受关注的行刑尝试最终陷入混乱，并引发了迫切的医学疑问。
A high-profile execution attempt in Nashville ended in chaos and raised urgent medical questions after Tennessee death row inmate Christa Gail Pike survived two separate doses of lethal pentobarbital, the Associated Press reported.
根据美国国立卫生研究院（NIH）医学专家的说法，戊巴比妥是一种短效巴比妥类药物。
Pentobarbital is a short-acting barbiturate, according to medical authorities at the National Institutes of Health (NIH).
历史上，戊巴比妥曾被用作镇静剂、抗癫痫药物或安眠药，它能增强大脑主要抑制性神经递质GABA的活性，从而减缓整个中枢神经系统的活动。
Historically prescribed as a sedative, anti-seizure medication or sleep aid, pentobarbital enhances the activity of GABA, the brain's primary inhibitory neurotransmitter, slowing activity throughout the central nervous system.
田纳西州死囚在一次失败的行刑尝试中挺过两次致命注射剂量的戊巴比妥。在临床医学中，戊巴比妥曾被用于多种用途，包括以下方面。
TENNESSEE DEATH ROW INMATE SURVIVES 2 LETHAL INJECTION DOSES IN FAILED EXECUTION ATTEMPT In clinical medicine, pentobarbital has been used for several purposes, including the following.
由于风险较低且更安全的更新药物在很大程度上已在医院环境中取代了巴比妥类药物，戊巴比妥现在在常规患者护理中已极少使用。
Because newer, safer drugs with lower risks of overdose have largely replaced barbiturates in hospital settings, pentobarbital is now rarely used in routine patient care.
然而，据美国国家医学图书馆、美国食品药品监督管理局（FDA）批准的兽药标签以及死刑信息中心称，它仍然是美国几个州实施兽医安乐死和死刑注射方案中的主要药物。
However, it remains a primary agent in veterinary euthanasia and lethal injection protocols across several U.S. states, according to the National Library of Medicine, FDA-approved veterinary drug labeling and the Death Penalty Information Center.
在高剂量死刑注射方案中，戊巴比妥通过静脉以大剂量的超致死量进行注射——通常为2.5至5克（远超临床治疗剂量）。
In a high-dose lethal injection protocol, pentobarbital is administered intravenously in large, ultra-lethal quantities — typically 2.5 to 5 grams (far exceeding clinical therapeutic doses).
法官叫停阿拉巴马州的氮气行刑方式，裁定其属于违宪的残酷刑罚。根据医学消息来源，当直接注射入静脉时，其进程分为三个阶段。
JUDGE BLOCKS ALABAMA'S NITROGEN GAS EXECUTION METHOD, RULES IT IS UNCONSTITUTIONALLY CRUEL When injected directly into a vein, the progression follows three stages, according to medical sources.
现年50岁的派克因1995年谋杀同班同学科琳·斯莱默（Colleen Slemmer）而被定罪，她原本将成为田纳西州200多年来第一名被执行死刑的女性。
Pike, 50, who was convicted in the 1995 murder of classmate Colleen Slemmer, was slated to become the first woman executed in Tennessee in more than 200 years.
据媒体目击者称，在长达一个多小时的过程中，派克隔着紧闭的帘子询问她的手臂是否应该有那种感觉（灼痛），并且呼吸不匀、发出清晰的鼾声。
Media witnesses observed her asking if her arm was supposed to feel that way (burning), breathing raggedly, and audibly snoring behind closed curtains over an hour-long span.
这起事件促使田纳西州州长比尔·李暂停该州所有尚未执行的死刑，等待独立调查结果。
The incident prompted Tennessee Governor Bill Lee to halt all remaining executions in the state pending an independent investigation.
