田纳西州当局正在展开调查，此前纳什维尔一家医院发生药物调配失误，导致患者在本应例行的手术过程中出现并发症。
此次失误发生于8月14日周五，地点是圣托马斯中城医院（Ascension Saint Thomas Midtown）。据CBS下属电视台WTVF报道，4名患者在接受关节置换手术时，被注射了钾剂而非标准止痛药物。所有手术原本都应作为门诊流程完成，WTVF报道称。
目前尚不清楚药物是如何被混淆的。
医院院长兼首席执行官舒布哈达·贾加西亚（Dr. Shubhada Jagasia）在一份声明中表示，医院在事件发生当天就得知了这一“状况”。贾加西亚称，医院已主动向州监管机构报告此事，并启动了内部调查。
“我们已查明原因并落实了纠正性安全防范措施，”贾加西亚说道。她未具体说明失误原因或正在实施的防范措施，但表示临床团队“正在积极采用这些强化后的安全规程，以确保医院达到最高安全标准”。

田纳西州调查局告诉CBS新闻，在田纳西州医疗设施委员会通报这起事件后，该局已正对此次药物调配失误展开积极调查。
贾加西亚表示，医院工作人员已与受影响患者的家属会面。她称医院不会披露受影响患者的“具体临床细节”。
钾剂在医院中有多种用途。钾本身是人体维持正常运转所需的必需矿物质和电解质。柠檬酸钾可用于治疗肾结石，氯化钾则有助于维持心脏和神经功能。然而，钾摄入量过多会带来危险：高剂量氯化钾曾被用于死刑执行。
Drug mix-up at Nashville hospital causes complications in 4 patients

Tennessee authorities are investigating after a drug mix-up at a Nashville hospital caused patients to experience complications during what should have been routine surgeries.
The error occurred at Ascension Saint Thomas Midtown on Friday, Aug. 14. CBS affiliate WTVF reported that four patients had received doses of potassium instead of standard pain drugs while undergoing joint replacement operations. All of the operations were supposed to be outpatient procedures, WTVF reported.
It’s not clear how the medications became mixed up.
Dr. Shubhada Jagasia, the hospital president and CEO, said in a statement that the facility became aware of the “event” the day it occurred. Jagasia said the hospital self-reported to state regulators and launched an investigation.
“We identified the cause and have implemented corrective safeguards,” Jagasia said. Jagasia did not specify what the cause of the error was or which safeguards were being put in place, but said clinical teams are “actively using these enhanced safety protocols to ensure the highest level of safety” at the facility.

The Tennessee Bureau of Investigation told CBS News it is actively investigating the mix-up after the Tennessee Healthcare Facilities Commission alerted it to the incident.
Jagasia said hospital staff have met with the families of the impacted patients. Jagasia said the hospital would not share “specific clinical details” about the affected patients.
Potassium has a number of uses in hospitals. Potassium itself is an essential mineral and electrolyte that the body needs to maintain a certain level of to function. Potassium citrate can be used to treat kidney stones. Potassium chloride can support heart and nerve function. However, too much potassium can be dangerous: High doses of potassium chloride are used in executions.
