BACKGROUND: The mechanically ventilated patient's stay in the emergency department (ED) is brief but ventilatory management and intervention must be optimal. Agitation, anxiety, distress, and discomfort are common complications far the ventilated patient. So, sedation is necessary to reduce these complications. METHODS: Patients were monitored and mechanically ventilated. Midazolam was intravenously administered as loading dose(3-5mg), followed by continuous infusion at a rate of 0.06mg/kg/hr, titrated to achieve a predetermined sedation level (Ramsay's sedation score: 2-5 points, Glasgow coma score scathe : 8-11 points). RESULTS: After onset of predetermined sedation, systolic and diastolic blood pressure and heart rate remained stable during continuous infusion when compared with those of the initial state. Arterial blood gas and peak inspiratory pressure remained unchanged but respiratory rate was decreased to allowable ranges. CONCLUSION: A short-term continuous infusion of midazolam was a safe and erective method for sedation of ventilated patients in ED.

Pedicled bone flap raised from the volar aspect of lower end of the radius, pedicled by the pronator quadratus has been used for the treatment of scaphoid nonunion and Kienbock's disease. From July 1991 to Jan. 1992, authors performed this procedures for 3 cases of Kienbock's disease. Patients were 2 cases in the left hand, l case in the right hand. There was no critial trauma history. Age at operation were 25, 37 and 57 years. All patients were in Stage I in 2 cases and stage II-A in 1 case of Lichtman's radiologic classification. Preoperative grip powers were 11%, 38%, 63% and pinch powers were 20%, 41%, 61% of that of normal opposite hand. Follow up periods were 28, 31 and 33 months. At last follow up roentgenographic finding shows no progression of necrosis of lunate, new bone formation, decreased sclerosis, and joint space were preserved in all cases. The fuctional results at the last follow up were as follows. Pain during motion was markedly diminished in all patients. Grip power were 57%, 89% and 96% and pinch powers were 68%, 83% and 100% of that of normal opposite hand with use of calibrated Jamar dynamometer which showes significant increase than preoperative state. The ranges of motion of wrist were as follows. Volar flexion were 40, 45 and 80 degree. Dorsiflexion were 10, 20 and 45 degree. Ulnar deviation were 10, 20 and 30 degree. Radial deviation were 10, 25 and 30 degree. This viable bone graft with blood supply gives very satisfactory clinical results.

OBJECTIVES: Manganese is cytotoxic to the central nervous system including basal ganglia. Its toxic mechanism is related to oxidative stress, mediated by toxic free radicals but is specultives. In the present study, we have investigated to manifest apoptosis in manganese-induced cytotoxicity in primary neuronal cell culture of rat basal ganglia. METHOD: To detect apoptotic neuronal cells were stained by the terminal deoxynu-cleotide(TdT)-mediated dUTP nick end-labelling(TUNEL) method and apoptotic changes in nuclei of neurons were observed by electron microscopy. RESULTS: We showed that TUNEL immunostain showed brownish signal in the nuclei of apoptotic cells and the proportions of apoptotic cells in Manganese treatment groups were more higher than controls. On transmission electron microscopy, there were chromatine condensation with margination toward nuclear membrane and condensation of cytoplasm in the treated with luM MnC1, for 48 hours in a basal ganglia neurons. Apoptotic bodies were found and consisted of semilunar-like condensed nuclei with relatively intact cytoplasmic organelles. CONCLUSIONS: Apoptosis appears to be one mechanism in the manganese-induced neuronal cell death. Manganese intoxication is a convenient model for apoptosis study.
