3.The Influence of Unilateral Spinal Anesthesia and Conventional Spinal Anesthesia on Sensitivity to Midazolam Sedation.
Korean Journal of Anesthesiology 2005;48(1):39-44
BACKGROUND: Spinal anesthesia potentiates sedative drug effects. We speculated that an acute decrease in tonic afferent input by spinal anesthesia would decrease the level of consciousness and thereby increase susceptibility to sedative drugs. The experiments were approached with the assumption that the amount of sedative would reduce in the following order: first, the group without spinal anesthesia, second, the group with unilateral spinal anesthesia, and third, the group with conventional spinal anesthesia. METHODS: Patients in group 1 (n = 20) were given midazolam without spinal anesthesia and patients in group 2 (n = 20) received unilateral spinal anesthesia. Those patients who after 20 minutes had a sensory level of T9-11 and a motor block of 3 in dependent side, no sensory block, and a motor block of 0 in the non-dependent side were included. In group 3 (n = 20), patients received conventional spinal anesthesia, and those patients who after 20 minutes had a sensory level of T9-11 and a motor block of 3 were included. The amount of midazolam administered at 33microgram/kg/min to a Bispectral Index score (BIS) of 80 was measured. RESULTS: The dose of midazolam administered to a BIS of 80 was significantly lower in group 3 than in group 1 or group 2. CONCLUSIONS: The sensitivity of sedatives was in the following order: the group with conventional spinal anesthesia, the group with unilateral spinal anesthesia, and the group not administered spinal anesthesia.

PURPOSE: We analyzed the clinical outcome of osteosarcoma developed in distal radius and the effect of delayed treatment on prognosis. MATERIALS AND METHODS: Twelve patients with distal radius osteosarcoma were analysed. We categorized patients into two groups of standard treatment or non-standard treatment. The patients of standard treatment group are all stage IIB and non-standard treatment group includes five stage IIB and one stage III. RESULTS: Five-year overall survival and disease-free survival rates of standard treatment group were 100% and 83%. Five-year overall survival rate of non-standard treatment group was 44%. Between two group, there are differences in age, tumor size, surgery type, symptom duration. CONCLUSION: Distal radius osteosarcoma have good prognosis than other extremity osteosarcoma. Survival rate of non-standard treatment group were lower than standard treatment group. Although the prognosis of non standard treatment group is poorer, the duration till death was longer than that of other sites with similar condition. Further multi-institutional study should be needed.

Rheumatoid arthritis is a chronic inflammatory systemic disease of young or middle aged adults, characterized by destructive and proliferative changes in the synovial membrane, periarticular structures, skeletal muscle and perineural sheath. Eventually, the joints are destroyed, ankylosed and deformed. Therfore, the aim of treatment is to keep the inflammatory process at a minimum, thereby preserving the joint motion, maintaining the health of muscle supplying motor power about the joint and preventing secondary joint stiffness and deformity. Surgical treatment in rheumatoid arthritis has progressed and there have been advances in the relief of pain and increase in the range of motion. Among them the results of total knee arthroplasty (TKA) have improved steadily during the past decade due to refinements in design, fixation, and surgical technique. At orthopedic department of seoul national university hospital, we performed 31 total knee replacement in 18 patients who had suffered from rheumatoid arthritis during the period from Aug. 1982 to Dec. 1988. Following results were obtained. 1. Knee score increased from 37.8 to 76.9. 2. Tibio-femoral angle was corrected from 0.9° valgus to 5.3° valgus. 3. Conplications were peroneal nerve palsy in 3 knees, instability in 1 knee, tuberculous arthritis in 1 knee. 4. In 25 out of 31 knees, good functional results were obtained.

From Sept. 1987 to Mar. 1993, 14 cases of pelvic bone tumors took surgical treatment. Male to female ratio was 7:7, with an average age of 31.9 years. Pathological diagnosis were chondrosarcoma 7(1 ; secondary), metastatic thyroid cancer 2, and each one case of giant cell tumor, desmoplastic fibroma, metastatic synovial sarcoma, malignant fibrous histiocytoma(MFH), and enchondroma. According to the Enneking's classification for the type of surgical resection, we performed 4 cases of type II+III resection, 4 type IA, 2 type I+II, 2 type III, and each one of II and IIA+III. Types of reconstruction were hip fusion(3 cases), heat treated autogenous bone graft combined with total hip replacement arthroplasty(4), bone graft(2), cement spacer(1) or saddle prothesis(1). Simple resection was done for 3 cases. Wide surgical margin was achieved in 12 cases, marginal margin in 1 and intralesional magin in 1. Complications occurred in 3 cases(21.4%) : 1 graft failure ; 1 lymphedema ; and 1 delayed union. The average follow-up period was 27.4(8-60) months. During follow up, lung metastasis developed in MFH case but no local recurrence was noted in all. By the criteria of American Musculoskeletal Tumor Society(MSTS), the average score for functional activities was 21(70% of normal). The function of the extremity with reconstructed or undestroyed pelvic ring was better than that with disrupted pelvic ring(functional scores ; 24.6 vs 12.3 respectively). Due to the Korean life style using hypocaust, fused hip was not good for indoor activity. For the malignant pelvic bone tumor not involving femoral neurovascular bundle, limb-salvage using internal pelvectomy and reconstruction of pelvic ring can be indicated as a surgical procedure, instead of the hindquarter amputation.
