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.

PURPOSE: To investigate the clinical manifestations, management, and ophthalmologic complications of orbital roof fractures and zygoma fractures. METHODS: A retrospective survey of 119 patients who visited Korea University Medical Center from June 2009 to June 2010 was performed. The sex, age, causes, fracture characteristics, neurologic injury, ocular injury, and combined facial bone fractures of patients who were diagnosed with orbital roof fracture and zygoma fracture were statistically analyzed. RESULTS: The mean age of patients with orbital roof fracture was 33.0 years old. The most common cause of orbital roof fracture was traffic accident (36.1%) with 6 patients receiveing surgical treatement (9.8%). Among the ophthalmologic diagnoses of the patients with orbital roof fracture, traumatic iridocyclitis was the most common (7 eyes) followed by eyeball rupture (2 eyes). The mean age of patients with zygoma fracture was 36.6 years old. The most common cause of zygoma fracture was traffic accident (32.8%), with 51 patients receiving surgical treatement (87.9%). Among the ophthalmologic diagnoses of the patients with zygoma fracture, traumatic iridocyclitis was the most common (6 eyes), followed by commotio retina (4 eyes). CONCLUSIONS: The present study regarding clinical characteristics and treatment of orbital roof fracture and zygoma fracture is helpful for ophthalmologists regarding the treatment of accompanying ophthalmologic complications.
