Mastectomy for Breast Cancer Under Regional Anesthesia Utilizing Intertransverse Process Block in a Patient...

General anesthesia for patients with poor pulmonary function is a risk factor for perioperative pulmonary complications, and it should be avoided as much as possible, depending on the specifics of each case. Herein, anesthetic management for partial mastectomy in a patient with poor pulmonary function using intertransverse process block (ITPB) is reported. A woman in her 80s (height 149 cm, weight 45.9 kg) was scheduled to undergo a partial mastectomy for right breast cancer. She had bronchiectasis and interstitial pneumonia. ITPB was performed, and intravenous dexmedetomidine and lidocaine with epinephrine were administered locally. There was no worsening of dyspnea during surgery, and the patient was discharged on the seventh postoperative day without any complications.
