RESUMEN
Two patients, aged 73 and 58 years, with diffuse pulmonary fibrosis underwent emergency open cholecystectomies (subcostal approach) under thoracic epidural anesthesia with 0.5% ropivacaine and fentanyl in spontaneous ventilation. Pulmonary fibrosis was due to amiodarone administration in the first patient and of unknowon cause in the second. Both developed arterial hypotension without bradycardia in spite of optimal preloading. Inotropoic support with low doses of norepinephrine was requiered for recovery in both cases with no adverse events after reversion of the sympathetic blocks. Postoperative epidural analgesia was very satisfactory. Thoracic epidural anesthesia is a useful alternative to general anesthesia for subcostal cholecystectomy in patients with diffuse interstitial lung disease in advanced stages.
