In recent years there has been an increase in the number of outpatient surgical procedures performed using local anesthesia with intravenous sedation. However, many patients are reluctant to undergo surgery because of their concerns about pain and pain-awareness during the operation. We performed a study to evaluate the effectiveness and safety of midazolam during outpatient surgical procedures. Between March 1997 and December 1998, 50 patients were anesthetized with bolus intravenous injection of 0.1mg/kg of midazolam, followed by local anesthesia. The blood pressure, pulse and oximeter values were monitored. There was no significant change of arterial oxygen saturation. Midazolam induced antegrade amnesia in most cases. All patients except three (94%) said they would willingly choose this anesthetic technique again. Major complications were not noted. We concluded that midazolam is a good sedative agent in providing favorable antegrade amnesia, as well as reduced anxiety and fear of pain during surgical procedures. This suggests that midazolam may be used routinely in outpatient surgical procedures. Monitoring of oxygen saturation, however is essential in preventing severe hypoxia during procedures.

Early detection of skeletal disorders was very important role in establishing therapeutic modality and prevention of complications. Since Tc-99m-phosphates derivatives used in bone scan agent, remarkable improvement was noted in effectiveness, cost, radiation hazard to patient and image quality than previously used agents such as strontium or fluoride. Bone scan with Tc-99m-MDP was done in 155 cases for early diagnosis of skeletal disorders at Severance Hospital, College of Medicine, Yonsei University from August, 1980 to May, 1982 were analyzed both clinically and radiologically, and the following results were obtained. l. Among 19 cases of avascular necrosis, positive cases were 17 (89.5%) in bone scan and 6(31.6%) in X-ray. Positive pattern could be classified into 3 types and the radionuclide uptake in the femoral head was decreased in 3 cases which was negative in X-ray and duration of their symptoms was within 4 months. 2. Fifteen among 17 hip fractures or dislocations were positive in bone scan. In 12 (80.0%) among 15 cases, complications were revealed and positive cases in X-ray were 7(58.3%), which were all positive in bone scan. 3. In 20 bone scans for early diagnosis of acute osteomyelitis, positive in bone scan were 17 and 14 (82.4%) of 17 cases were finally diagnosed as acute osteomyelitis. Among 15 cases diagnosed as acute osteomyelitis, positive in X-ray were 8(53.3%) and sensitivity of acute osteomyelitis in bone scan was 93.3%. 4. In 25 cases of the suspected infection of the joint, 15 were positive in bone scan and among them, cases diagnosed as pyogenic arthritis were 12 (80.0%) and positive in X-ray were 2 (16.7%). Only one of 10 cases of transient synovitis of the hip joint was positive in bone scan. 5. In rheumatoid arthritis, 13 of 15 cases were positive in bone scan and 10 among them were revealed the diffuse uptake of the radionuclide in the joint. In degenerative arthritis, 7 of 8 cases were positive in bone scan and they were revealed the focal uptake of the radionuclide in the same site where the bone was changed in x-ray. 6. Among 28 cases showed spine fracture in X-ray after trauma, 15 (53.6%) were positive in bone scan. In spine fracture, it was difficult to differentiate fresh fracture from old fracture with bone scan. The positive duration of bone scen in fracture of weight bearing bone was longer than in spine fracture. Rib fracture which was not found in X-ray could be diagnosed with bone scan.

Spontaneous testicular hemorrhagic necrosis is a rare disease usually associated with testicular torsion. Partially involved and suspicious testis tumor cases are also defined from orchiectomy specimens. Herein, a spontaneous hemorrhagic necrosis, without any testicular torsion, but with involvement of the whole testicle and epididymis, is reported. A 21 year old patient, who presented with a painless left testicular enlargement of several days duration was believed, based on physical examination, ultrasonography and elevation of serum LDH, to have a testicular tumor. Diagnosis was made only after radical orchiectomy and histopathological examination.

STUDY DESIGN: This retrograde study was designed to compare the clinical features and postoperative clinical results of diabetic and non-diabetic patients who had undergone decompression and postero-lateral fusion with instrumentation. OBJECTIVE: To determine whether diabetes affected the outcome of surgery and to identify the clinical features associated with a poor outcome. SUMMARY OF BACKGROUND DATA: Symptoms of peripheral angiopathy and neuropathy as long-term complications of diabetes closely mimic those of lumbar stenosis and there may be a risk of inappropriate surgical intervention in patients with both diabetes and spinal stenosis. In the presence of diabetes, a poor surgical outcome might be expected. But only a few literatures have been documented. MATERIALS AND METHODS: We reviewed 21 diabetic(mean age 58.2 years) and 21 non-diabetic patients(mean age 61.3 years) who had undergone decompression and postero-lateral fusion with instrumentation for lumbar spinal stenosis at a mean of 32 months after operation by reviewing the medical records such as clinical symptoms and results of objective examination(including electrophysiologic study). RESULTS: The preoperative symptoms were similar in the two groups except that abrupt onset of symptoms, the presence of night pain and the absence of any posture-related pain relief were recorded only by diabetic patients. The level of decompression, co-morbidity rate, and intra-operative blood loss were similar in two groups, too. Nerve-conduction velocity was lowered in 66.7% of the diabetic and in 25% of the non-diabetic patients. Polyneuropathy, which are highly suspicious of diabetic neuropathy was detected 46.7% in only diabetic group. The long-term result was excellent or good for thirteen(61.9%) of the twenty-one diabetic patients and for nineteen(90.5%) of the twenty-one non-diabetic patients. CONCLUSIONS: Thus diabetic patients who haute spinal stenosis cannot be expected to have same clinical outcome as non-diabetic patients, which is consistent with the general belief of impression. Therefore, the selection of patient according to clinical and electrophysiologic findings would be the most important factor in determining the rate of success of surgical treatment.

Disseminated intravascular coagulation (DIC) is a pathological syndrome in which activation of coagulation cascade leads to fibrin clot formation, consumption of platelets and coagulation factors, and secondary fibrinolysis. We report a case of severe postoperative hemorrhagic diathesis due to DIC. A 59-year-old man was scheduled for reduction of tibia fracture and anatrophic nephrolithotomy of staghorn calculi. On the fifth postoperative day, second operation was performed for nephrectomy due to perirenal hematoma. Two days later, third operation was performed for hemostasis because of the continuous bleeding. Coagulation tests showed positive DIC profiles of thrombocytopenia, hypofibrinogenemia, increased fibrin degradation products, and prolonged prothrombin time and thrombin time. The patient recovered uneventfully and discharged on the 59th postoperative day.

BACKGROUND: The purpose of this study was to compare prospectively two different anesthetic techniques with isoflurane or propofol for postoperative nausea, vomiting and recovery after tonsillectomy in children. METHODS: Sixty children, ASA physical status I, were assigned randomly to one of two groups. In group I, anesthesia was induced with thiopental 5 mg/kg and maintained with isoflurane 1~1.5 vol%. In group P, anesthesia was induced with fentanyl 1 mcg/kg, propofol 2 mg/kg and maintained with propofol infusion 5~10 mg/kg/hr. Both group received vecuronium 0.1 mg/kg for tracheal intubation and were ventilated with 33% O2 in N2O. The time to extubation, time to eye opening, PACU time, incidence and numbers of postoperative nausea and vomiting, and degree of sedation were recorded as well as perioperative complications. RESULTS: There were no significant difference in the duration of anesthesia and PACU time between two groups. The time to extubation and eye opening of group P were significantly shorter than group I (p<0.05). The degree of sedation and incidence of postoperative nausea and vomiting of group P were significantly lower than group I (p<0.05). But the frequency of intraoperative bradycardia was significantly higher in group P than group I (p<0.05). CONCLUSIONS: Propofol-fentanyl anesthesia results in less nausea and vomiting during postoperative period and more rapid recovery compared to isoflurane anesthesia and may be recommended in children undergoing tonsillectomy and adenoidectomy.

Malposition of the extracorporeal membrane oxygenation (ECMO) venous cannula in the azygos vein is not frequently reported. We hereby present such a case, which occurred in a neonate with right-sided congenital diaphragmatic hernia. Despite ECMO application, neither adequate flow nor sufficient oxygenation was achieved. On the cross-table lateral chest radiograph, the cannula tip was identified posterior to the heart silhouette, which implied malposition of the cannula in the azygos vein. After repositioning the cannula, the target flow and oxygenation were successfully achieved. When sufficient venous flow is not achieved, as in our case, clinicians should be alerted so they can identify the cannula tip location on lateral chest radiograph and confirm whether malposition in the azygos vein is the cause of the ineffective ECMO.

OBJECTIVE: To evaluate the current status and new trends in gynelcological pelviscopy in Korea. METHODS: A survey was conducted and analyzed based on 20997 cases of operative pelviscopy hom May, 1985 to February, 1998 reported from twenty four university hospitals in Korea. RESULTS: The results obtained were ss followings; 1) 45.9 % of the total cases was 30 to 39 years old age group and it was the most dominant age group, 2) The previous operative history was found in 10.9% of the tota1 cases and included cesarean section(30.0%), ectopic pregnancy(20.3%), etc. 3) The operative indications were diagnostic(26.2%), myoma uteri(23.1%), ectopic pregnancy(21.4%), adnexal mass(18.4%), etc. In cases of diagnostic indication, the most common post-operative diagnosis of pelviscopic surgery was tubal pregnancy(30,6%). 4) The operative titles were salpingectomy(25.1%), hysterectomy(19.9%), salpinghorectomy(19.8%), etc. 5) The complications of operative pelviscopy were composed of subcutaneous emphysema(0.58%), preperitoneal bleeding(0.3%), bladder injury(0,3%), bowel injury(0.3%), etc. 6) lhe survey showed that 57.1% of the respondents desired more than 1 year of period for well peration between the operator and the assistant. 56.7% of respondents indicated that the surgical technique of the operator was the most important factor for a successful pelvisocopic surgery. 7) The most beneficial effect of the pelviscopy included the comfortableness of the patient(40.0%), cosmetic effect(22.8%), decrease of complications(14.2%), etc. CONCLUSION: The modem methods of operative pelviscopy have been successfully used in the treatment of gynecological disease. Today, pelviscopic surgery is being applied in almost all the cases of gynecological disease. Hence, the majority of pelviscopy techniques and pracedures being performed by surgeon must be taught in the controlled setting of a residency or a fellowship training program.
