Comparative Study
[Effects of dexmedetomidine hydrochloride on postoperative sedation in cardiovascular surgery].
Postoperative assessment of brain damage in cardiovascular surgery is often obscured by sedatives. Therefore, early postoperative detection of brain attack and its treatment are also hampered. A newly approved sedative, dexmedetomidine hydrochloride has weak analgesic effect and no respiratory depressive effect. These characteristics allow early assessment of brain damage after surgery. In this report, we compared 2 sedatives, propofol and dexmedetomidine hydrochloride, in cardiovascular settings. ⋯ Dexmedetomidine hydrochloride has no major hemodynamic nor other side effects after cardiovascular surgery. Dexmedetomidine hydrochloride could be used as an effective agent for postoperative sedation and analgesia in cardiovascular settings.

We herein present 2 cases of metastatic lung tumor derived from uterine leiomyosarcoma. In the case 1, a 59-year-old woman was admitted to our hospital to examine abnormal shadow detected on chest X-ray. She had undergone hysterectomy and oophorectomy for uterine leiomyosarcoma 19 months previously. ⋯ Exploratory laparotomy revealed the tumor was unresectable, and she received 4 courses of chemotherapy (paclitaxel and carboplatin). For metastatic lung tumor from uterine leiomyosarcoma, surgery has been considered the best choice. However, for patients with uterine leiomyosarcoma who cannot be treated surgically because of multiple metastatic tumors or poor surgical risk chemotherapy (paclitaxel and carboplatin) or stereotactic radiotherapy can be strategies.
