In general, most postanesthesia complications of gastrointestinal surgery happen several days following the operation. They are life threatening, and immediate intervention is needed. A good example is the esophageal perforation following instrumentation of the esophagus: the patient is instructed to report to the surgeon any pain and fever after the surgery as they are signs and symptoms of a perforated esophagus. If the situation presents, an esophagram is immediately ordered to rule out any life-threatening complications. Surgery is the preferred treatment. Another postanesthesia complication is blood loss at the surgical site or internally. Patients are closely monitored for signs and symptoms (e.g., hypotension, tachycardia) of this serious complication (Schick & Windle, 2015).
