When patients in two cases did not receive complete preanesthetic evaluation, problems with intubation ensued. In the first case, an anesthesiologist went to evaluate a morbidly obese patient scheduled for hysteroscopy. As the patient was donning her hospital gown behind a closed curtain, he waited but left without performing the preoperative assessment because the morning surgery list was overbooked and he had many other patients to see. Once in the operating room, he discovered on chart review that the woman had a history of gastroesophageal reflux. She could not be intubated, and a supraglottic airway was placed. In the second case, an elderly man with a tumor mass at the base of his tongue was scheduled for a biopsy. On examination, the anesthesiologist could not see much of the mass with the patient's mouth maximally open and tongue sticking out, and he couldn't locate the patient's head and neck CT to further evaluate the mass. The surgeon arrived late and did not communicate with the anesthesiologist about the patient. After inducing general anesthesia, laryngoscopy and intubation proved extremely difficult as the mass obscured the view of the larynx. A second anesthesiologist was called, and together they were able to intubate the patient with a fiberoptic bronchoscope.

Prior to surgery, an anesthesiologist and surgical physician assistant noted a patient's allergy to IV contrast dye, but no order was written. During a time out before the procedure, an operative nurse raised concern about the allergy, but the attending anesthesiologist was not present and the resident did not speak up.

Several days after a patient’s surgery, preliminary wound cultures grew Staphylococcus aureus. Although the final sensitivity profile for the cultures showed resistance to the antibiotic that the patient was receiving, the care team was not notified and the patient died of sepsis.

A woman with a fractured right foot receives spinal anesthesia and nearly has surgery for trimalleolar fracture and dislocation of the left ankle. Only immediately prior to surgery did the team realize that the x-ray was not hers.

Owing to privacy concerns, a nurse draws the drapes on a 3-year-old child in recovery following surgery, and unfortunately does not realize the child is in distress until loud inspiratory stridor is heard.
