BACKGROUND: We conducted this study to verify whether a mechanical ventilator is adequate for cardiopulmonary resuscitation (CPR). METHODS: A self-inflating bag resuscitator and a mechanical ventilator were used to test two experimental models: Model 1 (CPR manikin without chest compression) and Model 2 (CPR manikin with chest compression). Model 2 was divided into three subgroups according to ventilator pressure limits (P(limit)). The self-inflating bag resuscitator was set with a ventilation rate of 10 breaths/min with the volume-marked bag-valve procedure. The mode of the mechanical ventilator was set as follows: volume-controlled mandatory ventilation of tidal volume (Vt) 600 mL, an inspiration time of 1.2 seconds, a constant flow pattern, a ventilation rate of 10 breaths/minute, a positive end expiratory pressure of 3 cmH2O and a maximum trigger limit. Peak airway pressure (P(peak)) and Vt were measured by a flow analyzer. Ventilation adequacy was determined at a Vt range of 400-600 mL with a P(peak) of < or = 50 cmH2O. RESULTS: In Model 1, Vt and P(peak) were in the appropriate range in the ventilation equipments. In Model 2, for the self-inflating bag resuscitator, the adequate Vt and P(peak) levels were 17%, and the P(peak) adequacy was 20% and the Vt was 65%. For the mechanical ventilator, the adequate Vt and P(peak) levels were 85%; the P(peak) adequacy was 85%; and the Vt adequacy was 100% at 60 cmH2O of P(limit). CONCLUSIONS: In a manikin model, a mechanical ventilator was superior to self-inflating bag resuscitator for maintaining adequate ventilation during chest compression.

Wegener's granulomatosis is a disease of unknown etiology that is characterized by the clinicopathologic complex of necrotixing granulomatous vasculitis of the upper and lower respiratory tract, glomerulonephritis, and variable degrees of small vessel vasculitis. Recently Antineutrophil Cytoplasmic Antibody (ANCA) has been reported to be a highly specific test for the diagnosis of Wegener's granulomatosis. We have experienced a patient of Wegener's granulomatosis in a 11 year old girl who was admitted with complaints f arthralgia, hematuria, convulsion and associated with otitis media and sinusitis. Serologic test of C-ANCA was positive and histologic findings of the kidney showed crescentic glomerulonephritis with sclerosis and surrounding infiltration of multinucleated giant cells. Patient was treated with pulse methylprednisolone without improvement. The clinical course progressed rapidly and expired due to the renal failure, gastrointestinal bleeding and status epilepticus. A brief review of literatures was made.

PURPOSE: To compare the clinical outcomes between patients undergoing argon laser trabeculoplasty (ALT) and those undergoing selective laser trabeculoplasty (SLT). METHODS: Sixty-one eyes of 61 patients with primary open-angle glaucoma who were treated with more than 1 kind of antiglaucoma medication eye drop were enrolled in this study. Thirty-five eyes of 35 patients were treated with argon laser trabeculoplasty (ALT). Twenty-six eyes of 26 patients were treated with selective laser trabeculoplasty (SLT). The mean IOP at 1, 3, 6, and 12 months and the success rate of treatment at the 12-month follow-up period were evaluated in all patients. RESULTS: At 12 months postoperative, the ALT group had a mean IOP of 16.53+/-2.58 mmHg with a mean IOP reduction of 35.27%, while the SLT group had a mean IOP of 18.40+/-5.61 mmHg with a mean IOP reduction of 17.37%. The success rates of treatment defined as definition 1 were 62.85% in ALT and 62.50% in SLT, and the success rates defined as definition 2 were 51.42% in ALT and 46.15% in SLT. CONCLUSIONS: There were no significant differences in the IOP lowering effect or success rates between the ALT and SLT patients at 12 months postoperatively.
