Elise Orvedal Leiten, MD, and Rune Nielsen, MD, PhD; January 2019
Hospitalized in the ICU with hypoxic respiratory failure due to community-acquired pneumonia, an elderly man had increased pulmonary secretions on hospital day 2 for which the critical care provider decided to perform bedside bronchoscopy. Following the procedure, the patient was difficult to arouse, nearly apneic, and required intubation. The care team paused and discovered that after the patient had received 2 mg of intravenous midalozam, his IV line had been flushed with an additional 10 mg of the benzodiazepine, rather than the intended normal saline. This high dose of midazolam led to the respiratory failure requiring intubation. On top of that, instead of normal saline, lidocaine had been used for the lung lavage.

In a simulation exercise conducted in an institution that felt it was prepared for patients with actual or suspected Ebola, a man presented to the emergency department with symptoms of nausea, vomiting, and fever. He had recently returned to the US from Sierra Leone. The nurse initiated an isolation protocol and the critical care team all donned personal protective equipment. During transport, confusion about which elevators to use potentially exposed 30 staff members to Ebola. Additional issues occurred including breaching sterile technique while inserting a central line and confusion about the process to transport the patient's blood to the lab.

A patient with ALS was hospitalized with presumed pneumonia and sepsis. Although he was treated with broad-spectrum antibiotics and fluid resuscitation, additional potassium was administered due to his potassium level remaining low. The patient went into cardiac arrest and resuscitation attempts were unsuccessful.

A man with atrial fibrillation underwent ablation in the catheterization laboratory under general endotracheal anesthesia. The patient was extremely stable during the 7-hour procedure with vital signs hardly changing over time. Inadvertently, the noninvasive blood pressure measurement stopped recording for 1 hour but went unnoticed. After the error was discovered, the case continued without any problems and the patient was discharged home the next day as planned.
Don C. Rockey, MD; July-August 2014
Presenting with jaundice and epigastric pain, a woman with a history of multiple malignancies was admitted directly for an ultrasound-guided liver biopsy. After the procedure, the patient had low blood pressure and complained of new abdominal pain, which worsened over the next 2 hours. The bedside nurse soon found the patient unresponsive.
Raymond L. Fowler, MD, and Melanie J. Lippmann, MD; July-August 2014
During a code blue, an intraosseous line was placed in the left tibia of an elderly woman after several unsuccessful attempts to obtain peripheral venous access. Following chest compressions and advanced cardiovascular life support protocol, spontaneous circulation returned and the patient was transferred to the intensive care unit. A few hours later, the left leg was dusky purple with sluggish distal pulses.

Two days after knee replacement surgery, a woman with a history of deep venous thrombosis receiving pain control via epidural catheter was restarted on her outpatient dose of rivaroxaban (a newer oral anticoagulant). Although the pain service fellow scanned the medication list for traditional anticoagulants, he did not notice the patient was taking rivaroxaban before removing the epidural catheter, placing the patient at very high risk for bleeding.

While drawing labs on a woman admitted after a lung transplant, a nurse failed to clamp the patient's large-bore central line, allowing air to enter the catheter. The patient suffered a cerebral air embolism and was transferred to the ICU for several days.
Mark Ault, MD, and Bradley Rosen, MD, MBA; February 2013
A woman found unresponsive at home presented to the ED via ambulance. The cardiology team used the central line placed during resuscitation to deliver medications and fluids during pacemaker insertion. Hours later, a chest radiograph showed whiteout of the right lung, and clinicians realized that the tip of the line was actually within the lung.
Nancy Spector, PhD, RN ; March 2011
While caring for a complex patient in the surgical intensive care unit, a nurse incorrectly set up the continuous renal replacement therapy (CRRT) machine, raising questions about how new nurses should be trained in high-risk procedures.
Norma A. Metheny, RN, PhD; Kathleen L. Meert, MD; September 2008
A boy was receiving enteral feedings while recovering from a traumatic brain injury. The nasojejunal tube migrated to the gastric area, and the patient developed pneumonia, likely due to aspiration.
