Presentation‍

On October 12, a 70-year-old man came to the emergency department with dizziness, fatigue, pale complexion, tachycardia, left upper abdominal pain, and dark stools. He was seen by a gastroenterologist, who diagnosed upper gastrointestinal bleeding, duodenal ulcer on imaging, and acute blood loss anemia.

Physician action

‍On October 13 at 10:29 a.m., the patient was prepped and taken to the procedure room for an upper endoscopy by the gastroenterologist. An anesthesia assistant (AA) provided monitored anesthesia care (MAC) under supervision from an anesthesiologist. The procedure started at 10:35 a.m. The supervising anesthesiologist was not present when the procedure started.

The gastroenterologist identified several ulcers with exposed blood vessels. Unable to place clips on the vessels because of movements he associated with the patient's spontaneous breathing, the gastroenterologist asked the AA to make the patient temporarily apneic so he could place the clips. The AA attempted to deepen the anesthesia with additional propofol and maintained an almost constant jaw thrust for airway patency.
 
At 11:10 a.m., the AA placed a small nasopharyngeal airway to help with ventilation. Soon after, large amounts of blood were seen in the patient's mouth and nose. It was presumed the bleeding was coming from the nasal mucosa following the airway placement.  The AA injected oxymetazoline into the nostril, pressure was held, and frequent suctioning of the oropharynx was required. He then performed a direct laryngoscopy, found the vocal cords closed, and was unable to intubate the patient.
 
At 11:17 a.m., the anesthesiologist arrived and took over intubation attempts from the AA. The anesthesiologist believed they had successfully placed a 7.5 mm endotracheal tube; however, capnography did not show a carbon dioxide waveform. Oxygen saturation was soon noted as 80 percent from the patient's spontaneous breaths after the succinylcholine wore off. A new capnography module was brought into the room, but again no carbon dioxide was detected, indicating esophageal intubation.
 
At 11:18 a.m., the anesthesiologist removed the endoscopy tube and attempted another intubation, but carbon dioxide was still not detected. The patient developed hypotension, bradycardia, and hypoxia.
 
At 11:26 a.m., the patient had pulseless electrical activity, and full resuscitation efforts were started. Hand ventilation was described as difficult, and the patient did not respond. At 11:40 a.m., a repeat laryngoscopy showed esophageal intubation. The tube was removed, and another was properly inserted.
 
By 11:46 a.m., spontaneous circulation was restored. The patient was stabilized and transported to the ICU on full mechanical ventilation. On October 15, an MRI showed diffuse anoxic brain injury, and the patient remained unresponsive.  Life support was removed, and the patient died on October 25.

‍
Allegations‍

A lawsuit was filed against the anesthesiologist and the AA, alleging that they failed to use general anesthetic with a secure cuffed endotracheal tube. It was also alleged that they did not meet the standard of care in managing a patient with bleeding ulcers or known severe upper gastrointestinal bleeding. 

‍
Legal implications‍

A consulting expert for the plaintiff stated that the standard of care for a patient with a known or suspected upper gastrointestinal bleed during an upper GI endoscopy is to use a general anesthetic with either video assisted or traditional rapid sequence induction with a secured cuffed endotracheal tube for airway protection. He believed that the lack of an endotracheal tube was not safe in this instance due to the risk of pulmonary aspiration.
 
Consultants for the defense were mixed but generally more supportive of the anesthesiologist’s actions. They believed using MAC anesthesia met the standard of care. One expert was critical of the gastroenterologist for not communicating the high probability for blood in the stomach. This could have given the AA more time to intubate before a crisis developed.
 
This consultant also stated that blood and gastric secretions were filling the patient’s nose, not blood from the nasal airway. Confusion on proper endotracheal tube placement was noted as “understandable” given the malfunction of the ETCO2 tubing; the patient’s increased blood and secretions; and the patient’s unexpected anatomical challenges.
                 
Another defense expert was critical of the poor communication between the gastroenterologist and the anesthesia providers, stating that the anesthesiologist should have been called in sooner either by the AA or the gastroenterologist.

Disposition‍

This case was settled on behalf of the anesthesia assistant and the anesthesiologist.
