A 23-month-old male patient with treated bronchitis underwent a surgery for the repair of bilateral Hutch's diverticulum of bladder under general anesthesia. He treated bronchitis during 2 weeks since 3 weeks before operation. Arriving operating room, he had mild coughing with sputum. During anesthesia, he was well ventilated but endotracheal secretion was profuse. At ABGA of 2 hours after starting anesthesia, severe hypercapnea(PaCO2: 190.2 mmHg) and severe acidosis(PH: 6.746) were checked. Active treatment was done by suction of endotracheal secretion, hyperventilation, PEEP(5~10 cmH2O), increasing fresh gas flow rate(3.6 L/min --> 7 L/min), and administration of sodium bicarbonate, orciprenaline sulfate and methyl- prednisolone. After 3 hours of treatment, ABGA was normalized and symptoms including wheezing were relieved.

BACKGROUNDS: When measuring lung function and response to bronchodilator, MDI(metered-dose inhaler) is commonly used but unfamiliarity of its use and cold sensation by the puffed gas decrease reliability of the result. Spacer can reduce the cold freon effect and undesired oropharyngeal deposition caused by the rapid evaporation of the propellant and there are many studies which showed more effectiveness of spacer on the treatment of children with asthma but no study whether it is effective on the bronchodilator response test in the first medical examination of old age. Therefore, we tested whether the use of spacer can reduce the cold freon effect and improve the bronchodilator response in the first medical examination of old age. METHODS: Two hundred of elderly patients( 65years) who had never used MDI were measured the bronchodilator response. Subjects were randomised to either spacer-user or spacer-nonuser. Twenty minutes after 400 g fenoterol was administered, FEV1 (forced expiratory volume in one second) was measured. Bronchoconstriction was defined as a decrease in FEV1 by 10% or greater after bronchodilator inhalation. We further devided each group into normal or obstructive group, obstructive group was defined as FEV1<80% of predicted and FEV1/FVC<70%. RESULTS: In normal group, spacer-user(n=83) showed greater bronchodilator response than spacer-nonuser(n=66), 6.43% vs 3.81% respectively(p<0.05) and two case of bronchoconstriction occured only in spacer-nonuser. In obstructive group, there is no significant difference in bronchodilator response between spacer-user(n=18) and spacer-nonuser(n=33), 12.32% vs 11.16% respectively(p>0.05) but brochoconstriction(n=1) occured only in spacer-nonuser. CONCLUSION: Spacer improved bronchodilator response and prevented bronchoconstriction, in the first medical examination of old age.

Ipratropium bromide (IP) is a new anticholinergic bronchodilator. To evaluate its effect on bronchial asthma which is still unknown in Korea, a double blind and randomized study was done on all patients of bronchial asthma who visit out-patients clinic of out department from June to September 197 and showed 75 to 100% of FEV1/FVC ratio on prebronchodilator spirometry (pre BD). The selected patients were given 2 puffs of Fenoterol (FE) or Ipratropium inhalator blindly and Spirometry. The repeated results are: 1. In both FE and IP groups, there was a significant bronchodilatory effect on 5 and 60 minutes after administration. 2. One 5 minutes, effect of FE was significantly greater than IP (FVC p<0.05, FEV1 p<0.01). 3. One 60 minutes, effect of IP was slightly less than FE but statistically non-significant. On the basis of above results, we concluded that onset of effect of IP is slower than FE, but its effect is significant and nearly comparable to FE.

The mechanism of development of pulmonary edema associated with -sympathomimetic agent is still not fully understood. 2-sympathomimetic drugs such as ritodrine, terbutaline, and fenoterol are widely used for the treatment of premature uterine contraction. We describe a case of pulmonary edema that occurred suddenly during Cesarean section in a previously healthy parturient, associated with ritodrine pretreatment for 5 days in an attempt to arrest preterm labor. Pulmonary edema was completely treated with mechanical ventilation and diuretic therapy.

PURPOSE: To evaluate the effect of inhaled hypertonic saline solution in hospitalized infants with bronchiolitis. METHODS: A randomized double blind trial was performed from October 2003 to May 2004. A total of eighty patients <1 year of age with a clinical diagnosis of acute viral bronchiolitis were enrolled and assigned to receive either of the following:inhalation of 2 mL(0.5 mg) fenoterol added to 2 mL of 0.9 percent saline solution(group 1; n=40) or 2 mL(0.5 mg) fenoterol added to 2 mL of 3 percent saline solution(group 2; n=40). This therapy was repeated at six hours interval after admission. They were evaluated daily just before and 20 minutes after nebulization. The outcome measures included changes in clinical severity score(based on respiratory rate, presence of wheezing, retraction, and general condition) after nebulization and duration of hospitalization. RESULTS: In the clinical severity score, a significant improvement was observed during the 72 hours of hospitalization in both groups(P<0.05). The basic clinical severity scores before inhalation were decreased significantly faster in group 2 as compared to group 1 on each day of treatment(P<0.05). The mean duration of hospital stay was significantly reduced in group 2 than group 1(5.9+/-1.9 days versus 7.4+/-2.0 days, P<0.05). No adverse effects were associated with inhaled therapy. CONCLUSION: These results suggest that a nebulized 3 percent saline solution plus 0.5 mg fenoterol may be more effective than a 0.9 percent saline solution plus 0.5 mg fenoterol in accelerating the clinical recovery of infants with viral bronchiolitis.

PURPOSE: The Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines for chronic obstructive pulmonary disease (COPD) uses the post-bronchodilator spirometry for diagnosis and severity staging. We evaluated differences in the severity classification of COPD, based on pre- and post-bronchodilator spirometry. MATERIALS AND METHODS: From 2000 to 2004, 207 COPD patients who underwent spirometry before and after inhalation of 400 microg of fenoterol were analyzed. A responder to the bronchodilator test (BDT) was defined by the American Thoracic Society (ATS) as an increase in forced expiratory volume in one second (FEV1) or forced vital capacity > or = 12% and > or = 200 mL, and by the European Respiratory Society (ERS) as an increase in FEV1 > or = 10% of the predicted value. COPD severity was classified according to the 2008 GOLD guidelines. RESULTS: For the entire study population, the FEV1 increased by 11.8 +/- 12.5% of baseline after BDT and 41.1% and 27.1% of subjects were classified as responders using the ATS and ERS criteria, respectively. Based on pre-BDT spirometry, 55, 85, 58, and 9 patients were classified as Stage I-IV COPD, respectively. Sixty-seven (32.4%) patients changed severity staging after BDT, including 20.0%, 28.2%, 44.8%, and 66.7% of pre-BDT patients Stages I through IV, respectively. More ATS or ERS BDT-responders had a change in severity staging than non-responders (52.9% vs. 18.9% and 62.5% vs. 21.2%, both p < 0.001). CONCLUSION: Our data suggest that the severity staging of COPD using pre-BDT spirometry might lead to significant differences as compared to staging, based on post-BDT spirometry, as recommended by the current GOLD guidelines.

OBJECTIVETo evaluate the effectiveness of a helium-oxygen mixture (79%He- 21%O(2)) as an aerosolizing compressed gas for beta(2)-agonist therapy in patients with an asthma exacerbation.

METHODSTwenty-four patients in the outpatient department with a mild to moderate exacerbation of asthma were enrolled. The patients were randomly divided into an experimental group (13 cases) and a control group (11 cases). The experimental group inhaled Berotec with heliox-driven, and the control group inhaled Berotec with compressed air-driven. Eight hospitalized patients in the respiratory department with severe exacerbation of asthma were enrolled. The patients inhaled Berotec with heliox-driven or compressed air-driven in a random order.

RESULTSThe results of spirometric parameters and arterial blood-gas analysis were measured. In the mild to moderate asthma patients, no statistical differences between the two groups for forced vital capacity (FVC), forced expired volume in one second (FEV(1)), and expiratory flow in 50% forced vital capacity (FEF(50)) were presented. But the severe patients showed significant differences between heliox-driven and compressed air-driven for FVC, FEV(1), FEF(50) and partial pressure of oxygen (PaO(2)).

CONCLUSIONSCompared with the traditional inhalation of beta(2)-agonist therapy using compressed air-driven, the method of inhaling beta(2)-agonist with heliox-driven has more obvious benefits for those suffering from severe asthma. This is likely due to the cooperative effects between inhaling heliox on its physical gas properties and improving delivery of beta(2)-agonist in the treatment of exacerbation of severe asthma.
