Failure to intubate and prevent aspiration

Presentation

‍A 52-year-old man fell from a tree and fractured his ankle. His family brought him to the emergency department  (ED) of a local hospital at 8:30 p.m. The on-call orthopedic surgeon evaluated the patient and diagnosed a distal comminuted fracture of the left lateral tibia.

The patient was scheduled for surgery the next morning. The records indicate that he had a history of coronary artery disease, prior myocardial infarction (MI), hypothyroidism, and depression.
 

Physician action

‍An anesthesiologist performed a preoperative assessment the next morning. The patient's son, who was a paramedic, was present. During this interview, the anesthesiologist recommended a spinal anesthetic with endotracheal intubation. The patient's son wanted a general anesthetic in conjunction with a laryngeal mask airway (LMA). The anesthesiologist — who was told that the patient had not eaten since before midnight — agreed to this form of anesthesia. The patient had, in fact, eaten a large meal at 11 p.m. and was taking narcotics for pain.

The surgery was performed without complication until the anesthesiologist removed the LMA and noted that the patient had vomited. The anesthesiologist estimated that less than 1 cc had been aspirated and called for a pulmonology consult and pulmonary treatments.

At 2:14 p.m., eight minutes after arriving in the PACU, the patient vomited coffee ground emesis. A short time later, his oxygen saturations fell from the 70s into the 40s. The respiratory therapist arrived with equipment to intubate and ventilate the patient. The anesthesiologist told her that it was his decision to make and he did not want to intubate the patient. The respiratory therapist later testified that the anesthesiologist "blew her off."

At 3:15 p.m., the pulmonologist arrived and recommended that the anesthesiologist intubate the patient immediately. The patient was intubated at 3:17 p.m. and put on a ventilator.

The anesthesiologist recorded that the patient had suffered postoperative hypoxemia secondary to aspiration. The patient's family became very angry with the anesthesiologist and had him removed from the case.

The pulmonologist took over the care of the patient, who remained in ICU for 32 days with severe ARDS. The patient was also treated with medication for GERD while in the ICU. He was discharged to a rehabilitation facility. He progressed slowly during rehabilitation because of atrophy of his legs and foot drop.

A neurologist examined the patient and found that he had deficits in short-term memory and impaired speech. The patient was also depressed. An EEG revealed cerebral dysfunction in the left and right frontal temporal areas.

Allegations

‍A lawsuit was filed against the anesthesiologist and allegations included:

• failure to properly intubate the patient;
• failure to provide a safe anesthetic technique;
• failure to institute appropriate measures to prevent aspiration pneumonitis;
• failure to prevent and treat hypoxemia;
• failure to timely perform intubation;
• failure to correctly assess the severity of the patient's acute respiratory failure; and
• failure to properly document care of the patient and the risks associated with the anesthesia technique.

The patient claimed total disability due to the foot drop and is unable to work.

Legal implications

‍The defense was unable to locate an expert supportive of the defendant's actions. Overall, the anesthesiologists reviewing this case were critical of the delay in recognizing a significant aspiration event when the patient was in the PACU. When the patient vomited in the PACU, his oxygen saturations decreased for an extended period indicating possible ARDS. The reviewers felt that the anesthesiologist should have immediately intubated the patient and called for a pulmonology consult with bronchoscopy. The respiratory therapist was also very critical of the delay in intubation.

Reviewers were also critical of the decision to use LMA in a patient with a history of GERD and MI. The patient had a 'history that dictated protection of the airway.' However, it is unclear whether or not the family told the anesthesiologist that the patient had been treated for gastric reflux disease and UGI obstruction. Additionally, the anesthesiologist was not informed that the patient consumed a large meal at 11 p.m. while taking narcotics, which can delay gastric emptying.

The defense was able to develop significant arguments concerning causation and damages. During his deposition, the patient did not present himself as someone who has suffered a significant hypoxic injury. He answered all the questions but was very slow to speak and think. His primary complaints were associated with a foot drop.

While the plaintiff's neurology and neuropsychological experts believed the patient sustained anoxic brain damage, a neurologist who treated the patient following the incident had a different opinion. He agreed that the patient has cognitive impairments and memory deficits, but does not think the patient has neurological deficits. It is his opinion that the patient is depressed and is unable to deal with his life-changing injury.

Complicating the clinical issues were the actions of the anesthesiologist in altering the medical records. There are comments on the hospital copy of the anesthesia record that do not appear on the anesthesiologist's copy. The significant change to the record is the indication that the patient's head was elevated during surgery to prevent aspiration. Additionally, two sets of postoperative orders were found.
