Tachycardia in a Patient with Severe Pain


Case Study

A rapid response code was activated for a patient who developed persistent tachycardia on continuous telemetry. Upon the arrival of the condition team, the patient was noted to be a 60-year-old male with a past medical history of peptic ulcer disease and alcohol use, admitted two days prior for severe abdominal pain. The patient had undergone an esophagogastroduodenoscopy (EGD) a few hours before when the condition was called. EGD had shown evidence of gastritis. The patient had been started on proton pump inhibitors.

Vital Signs

  • Temperature: 97.6 °F, axillary

  • Blood Pressure: 170/90 mmHg

  • Heart Rate: 160 beats per min (bpm) ( Fig. 7.1 )

  • Respiratory Rate: 30 breaths/min

  • Oxygen Saturation: 99% oxygen saturation on room air

Focused Physical Examination

The patient was a middle-aged male who appeared diaphoretic and visibly uncomfortable. He was awake, oriented, and responding to questions. His abdominal examination showed epigastric tenderness but no distension or guarding. The remainder of his examination was unremarkable.

Interventions

A cardiac monitor and pads were attached immediately, with telemetry showing narrow complex, regular tachycardia. The patient was given 2 mg intravenous (IV) morphine immediately for pain relief. Electrocardiogram (EKG) was obtained, which showed sinus tachycardia. Complete blood count (CBC), electrolytes, lactate, amylase, and troponin level were ordered. The patient’s history of peptic ulcers and recent findings of EGD were noted. The patient was given a dose of antacid medication and sucralfate. An additional dose of 4 mg IV morphine was given for unresolved pain, and a chest/abdominal X-ray was obtained at the bedside, which was unremarkable. Stat computed tomography (CT) abdomen and pelvis were ordered, which showed findings consistent with acute pancreatitis. The patient was started on treatment for pancreatitis with adequate fluid hydration and a pain control regimen.
