Vagal nerve injury occurs when energy is applied to the posterior wall of the left atrium, resulting in acute pyloric spasms and gastroparesis. The patient presents with nausea, vomiting, bloating, weight loss, and abdominal pain within a few hours to a few weeks of the procedure. Nursing management includes preparing the patient for endoscopy, an MRI scan, or a gastric-emptying study. Though most cases improve over time, management options include small and frequent meals, botulinum toxin injection for pyloric spasms, prokinetic agents for gastroparesis, and gastric electrical stimulation with pacing. Surgical procedures such as gastrectomy, gastrostomy, and jejunostomy are considered in the most severe cases.
