Dyspnea attack due to hysteria after general anesthesia

: A 30-year-old female was scheduled for an expander insertion of the breast under local anesthesia. Thirty minutes after infiltration anesthesia with lidocaine and bupivacaine mixture, she suffered from dyspnea. She was intubated and transferred to our hospital. As her vital signs were stable and consciousness was clear, she was extubated in the emergency room. However, she was reintubated at night and ventilated mechanically for two days. Three months later, breast expander insertion was performed under general anesthesia. After extubation, dyspnea attack occurred and midazolam was injected. Seven months later, the reconstruction of TRAM flap was performed under general anesthesia and continuous subcutaneous injection of morphine was used for the postoperative analgesia. After extubation, she was sedated deeply and dyspnea attack did not occur. A month later, she was scheduled for the debridment and the resuture. Then, dyspnea attack occurred in the ward at night. The apnea monitor was attached to her in recovery room after extubation following the operation of debridment and resuture. Dyspnea attack appeared and was diminished with midazolam injection. We diagnosed her as hysteria with CMI and MMPI psychologic tests.
