Randomized Controlled Trial[Effect of different methods for postoperative pain management on catecholamine response to abdominal surgery].
To observe the effect of different analgesic methods and the influence of catecholamine response to elective abdominal surgery. ⋯ Postoperative patient-controlled epidural or intravenous analgesia could provide effective analgesia. Epidural anesthesia during operation or epidural analgesia postoperation could depress stress responses, thus it is a more effective analgesic method.

Randomized Controlled Trial Comparative Study[Comparison and correlative analysis of pulmonary function markers after extracorporeal circulation].
To compare the clinic significance of three lung function markers after cardiopulmonary bypass operation. ⋯ RI, OI and PaO2/PAO2 all can reflect appropriately the change of lung function after extracorporeal circulation and the monitor of the developmental alterations individually may be more instructive in clinical practice.

Randomized Controlled Trial[Effect of general and epidural anesthesia on autonomic nervous system].
To evaluate autonomic nervous tone during general and epidural anesthesia. ⋯ The autonomic nervous tone is inhibited by both epidural and general anesthesia. EA reveals a shift in the sympathovagal balance toward sympathetic predominance. GA is associated with a shift toward parasympathetic predominance intraoperatively, while postoperatively appears a dramatic increase in LF/HF. Relative to EA, there is a greater effect on autonomic nervous system with GA.

To analyze the surgical treatment results of 52 patients with sacral chordoma. ⋯ Complete resection of tumor (radical surgery when possible) is the most effective way to manage sacrococcygeal chordomas. Postoperative adjuvant radiation therapy can reduce the tumor recurrence rate, but it also can cause troubles that would hinder further surgical managements. Even if the tumor is relatively huge and the upper resection margin is as high as at S1 or S2 level, the tumor can be removed successfully by posterior approach and the postoperative complications could be accepted. Though proper surgical procedures and adjuvant radiation can control the tumor locally, we have no optimal methods to prevent metastases from developing or to cure them when they are detected. One patient who developed metastases in lungs received chemotherapy, and good curative effect had been observed.
