Additive effects of dexamethasone in nebulized salbutamol or l-epinephrine treated infants with acute bronchiolitis 总被引:1,自引:0,他引:1
BACKGROUND: Although it is the most common lower respiratory infection of infancy, the optimal treatment for acute bronchiolitis is still controversial. The aim of this study was to compare the early and late effects of nebulized L-epinephrine (EPI) and intramuscular dexamethasone (DEX) combination therapy with nebulized salbutamol (SAL) and dexamethasone combination and bronchodilators alone in outpatients with acute bronchiolitis. METHODS: A total of 69 infants aged 2-21 months who were admitted to the Pediatrics Department of the Faculty of Medicine, Mersin University, with acute bronchiolitis were included in a randomized, placebo-controlled, prospective trial study. Patients were assigned to receive either nebulized L-epinephrine (3 mg) or salbutamol (0.15 mg/kg) and 15 min later, either dexamethasone 0.6 mg/kg or placebo (PLA), intramuscularly, in a double-blind randomized fashion. The study groups were: epinephrine + dexamethasone group (group 1, n=23), salbutamol + dexamethasone group (group 2, n=23), epinephrine + placebo group (group 3, n=11), and salbutamol + placebo group (group 4, n=12). The outcome measures were heart rate, respiratory rate and Respiratory Distress Assessment Instrument (RDAI) score determined at 30, 60, 90 and 120 min, 24 h, and 5 days after the first therapy. Patients were then followed-up during the subsequent 2 months for the prevalance of respiratory complaints regarding bronchial hyperreactivity. RESULTS: There were no significant differences between the outcome variables of the four groups within the first 120 min and at 24 hours, or between the rates of requirement of a second dose of the same bronchodilator. However, fifth day RDAI score values of both DEX groups were significantly lower than that of SAL + PLA group (P=0.000 and P=0.01, respectively). The fifth day score value of group 1 was also significantly better than that value of EPI + PLA group but not different from group 2. CONCLUSIONS: A single dose of intramuscular dexamethasone added to nebulized L-epinephrine, or salbutamol therapies resulted in better outcome measures than bronchodilators alone in the late phase (fifth day) of mild to moderate degree bronchiolitis attack. However, effects of EPI + DEX combination was not different from SAL + DEX combination. 相似文献

Background: The objective of this study was to determine the efficacy and safety of nebulized 3% hypertonic saline solution and salbutamol in the treatment of mild to moderate bronchiolitis. Methods: In a randomized controlled trial, 93 infants with mild to moderate bronchiolitis were divided into two groups. The infants received inhalation of 2.5 mg (0.5 mL) salbutamol dissolved in either 4.0 mL normal (0.9%) saline (control group, n= 43) or 4.0 mL hypertonic (3%) saline (treatment group, n= 50). The therapy was repeated three times daily until discharge. Cough, wheezing, pulmonary physical signs, and the length of hospital stay were recorded. Results: Wheezing remission time was 3.8 ± 1.1 days in the control group and 2.7 ± 0.9 days in the treatment group (P < 0.01). Cough remission time was 6.3 ± 0.9 days in the control group and 5.3 ± 0.8 days in the treatment group (P < 0.01). The moist crackles disappeared at 5.4 ± 0.8 days in the treatment group versus 6.2 ± 0.9 days in the control group (P < 0.01). Furthermore, the average length of hospital stay decreased from 7.4 ± 1.5 days in the control group to 6.0 ± 1.2 days in the treatment group (P < 0.01). No obvious adverse effects were observed. Conclusions: Inhalation of nebulized 3% hypertonic saline solution and salbutamol is a safe and effective therapy for patients with mild to moderate bronchiolitis. 相似文献

The effects of injected adrenaline and nebulized salbutamol on acute asthma were compared in 46 children. The results showed that salbutamol had a significantly better bronchodilatory effect than adrenaline. Nebulized salbutamol is recommended as a primary method of treatment of asthmatic attacks in childhood. 相似文献

To test whether nebulized salbutamol (albuterol) is safe and efficacious for the treatment of young children with acute bronchiolitis, we enrolled 83 children (median age 6 months, range 1 to 21 months) in a randomized, double-blind clinical trial. Participants received two treatments at 30-minute intervals of either nebulized salbutamol (0.10 mg/kg in 2 ml 0.9% saline solution) or a similar volume of 0.9% saline solution placebo. Outcome measures were the respiratory rate, pulse oximetry, and a clinical score based on the degree of wheezing and retractions. Patients in the salbutamol arm had significantly greater improvement in clinical scores after the initial treatment (p = 0.04). There was no difference between the groups in oxygen saturation (p = 0.74); patients treated with salbutamol had a small increase in heart rate after two treatments (159 +/- 16 vs 151 +/- 16; p = 0.03). We conclude that salbutamol is safe and effective for the initial treatment of young children with acute bronchiolitis. 相似文献

Thirty-two children were treated with nebulized salbutamol for acute asthma. Seventy-five per cent of the treatments were efficient, either after a first nebulization at 0.15 mg/kg (47% = group I), or after a second nebulization 45 min later, at 0.05 mg/kg (27% = group II). Twenty-five per cent of the treatments (group III) were inefficient or only partly efficient. The clinical tolerance was good except in two children. Group I and II presented differences only for the auscultation score. Children from group I and II were older and had less severe asthma than those from group III. On the basis of this study, nebulized salbutamol appears to be an affective and safe treatment for acute asthma. The repeated administration of low doses, shortly after the first nebulization increases the quality of the response. 相似文献

The aim of this multi‐centre prospective study was to evaluate the efficacy, tolerability, and safety of the combination of sodium cromoglycate (SCG) and salbutamol (administered as a nebulized solution), compared to SCG alone and salbutamol alone, in the management of severe, intractable asthma in childhood. The study was an open, randomized, cross‐over trial of 12 weeks' duration in children with moderate‐to‐severe intractable asthma. All treatments were administered twice daily by powered nebulizer. The primary outcome measure was the change in asthma severity, as measured by the mean asthma score during the last 2 weeks of a baseline period and the last 2 weeks of each treatment. Secondary outcome measure was the patient's opinion of the effectiveness of treatment. The change in asthma scores from baseline values were significantly greater with the combination treatment compared to each component administered separately. The mean difference in asthma score between the combination and salbutamol was: ?7.5; 95% CI, ?11.70 to ?3.29 (p < 0.0001). The mean difference between the combination and SCG was: ?8.53; 95% CI, ?14.03 to ?3.25 (p < 0.0001). Patients were also significantly in favor of combination treatment (p < 0.001 vs. salbutamol; p < 0.01 vs. SCG). Two patients reported adverse effects. We concluded that regular twice‐daily inhalation of a combination of SCG and salbutamol gave better control of symptoms than previous treatments in patients with severe, intractable asthma. Few adverse effects with this therapy suggest that it is extremely useful, safe, and effective. 相似文献

Nebulized ipratropium bromide is though to be synergistic with albuterol in therapy for acute childhood asthma. Because the efficacy of ipratropium in bronchiolitis is uncertain and some infants with bronchiolitis do not respond to nebulized albuterol alone, the following study was undertaken. In this double-blind, placebo-controlled trial, 69 infants between 6 weeks and 24 months of age who exhibited the first episode of acute bronchiolitis were randomly assigned to receive either nebulized albuterol (0.15 mg/kg per dose) and ipratropium bromide (250 micrograms per dose) (group A, n = 36) or nebulized albuterol and normal saline (placebo) (group B, n = 33) for two doses, 1 hour apart. The two groups were comparable at baseline. Both therapies resulted in clinically significant improvement. However, the addition of ipratropium resulted in no additional benefit with respect to decrease in the respiratory rate (mean decreases 10.6/min vs decreases 8.6/min, P = .86), accessory muscle score (range 0 through 3) (decreases 0.92 vs decreases 0.82, z = -0.44), wheeze score (range 0 through 3) (decreases 0.94 vs 0.85, z = -0.20), oxygen saturation (increases 0.25% vs increases -0.33%, P = .86), or hospitalization rate (17 vs 10). The number of "nonresponders" and "clear responders" was also very similar in both groups. No toxicity was noted. The increase in heart rate was mild and similar in both groups (increases 6.7 vs increases 11.1). The power of the study to detect a difference between the two treatment groups in the respiratory rate change > or = 8/min is greater than 90%.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

Use of both l -epinephrine and racemic epinephrine (adrenaline) has improved clinical symptoms and composite respiratory scores in acute bronchiolitis. The objective of this randomized double-blind placebo-controlled study was to assess whether there was sufficient improvement in clinical state to reduce hospital admissions. Seventy-five infants aged 1 month to 1 year with a clinical diagnosis of acute bronchiolitis were treated with either 2 ml of 1:1000 nebulized adrenaline or 2 ml of nebulized normal saline administered after baseline assessment and 30 min later. Clinical respiratory parameters were recorded at 15-min intervals for a period of 2 h following the baseline assessment. Admission to hospital was the primary end-point and changes in respiratory parameters were secondary end-points. Fifty percent (19/38) of infants treated with adrenaline were discharged home compared with 38 percent (14/37) of those treated with saline. This 12 percent reduction in rate of admission is not statistically significant (95% CI of difference: −10% to 35%). There was no difference between treated and placebo groups in respiratory rate, oxygen saturation, heart rate or a composite respiratory distress score at 30, 60 or 120 min post-treatment. In this study, nebulized epinephrine did not confer a significant advantage over nebulized saline in the emergency room treatment of acute bronchiolitis. 相似文献

Objective : To see the additional benefit of combined frequent nebulization with salbutamol and ipratropium bromide in acute attack
of asthma with moderate severity.Methods : Fifty asthmatic children in the age range of 6–14 years were divided into two equal groups. Group I children were nebulized
with three doses of Salbutamol alone (0.03 ml/kg/dose) and Group II children were given combined nebulization of Salbutamol
(dose as in group I) and Ipratropium bromide (250 Μgm/dose for three doses) at 20 minutes interval. Children were observed
at 15, 30, 60,120,180 and 240 minutes interval.Results : A significant improvement in % of PEFR starting at 30 minutes and lasting the entire study period of 4 hours was noted
in both the groups. However on analysis of varience the results were better in group II.Conclusion : Frequent combined nebulization with Salbutamol and Ipratropium bromide is beneficial in acute asthma of moderate severity. 相似文献

Effect of salbutamol on respiratory mechanics in bronchiolitis 总被引:4,自引:0,他引:4
The effect of inhaled bronchodilators in bronchiolitis has been difficult to evaluate due to problems with techniques for assessing respiratory function in infants. Two new techniques were used to assess the response to inhaled salbutamol in 17 infants with bronchiolitis. With one technique, expiratory flow, volume, and airway occlusion pressure were measured and used to derive compliance (Crs) and conductance (Grs) of the respiratory system from a passive expiration induced by a brief end-inspiratory airway occlusion. With the other technique, the maximum flow at functional residual capacity (VmaxFRC) was measured from a partial maximum expiratory flow-volume curve generated by external chest compression. For the group, there was no change in compliance or conductance after salbutamol, but salbutamol caused a fall in maximum flow at functional residual capacity (p less than 0.01) and in the time constant of tidal expiration (p less than 0.01). The decrease in maximum flow at functional residual capacity with salbutamol is consistent with increased airway collapse on forced expiration. The decrease in tidal time constant suggests that the drug decreases expiratory braking. Presence of such braking activity may be an important strategy for maintaining lung volume. In summary, salbutamol failed to produce a beneficial effect on airways in bronchiolitis, but did produce changes in expiration which may be harmful in some infants. 相似文献

The response of bronchiolitis to bronchodilator drugs is controversial. The present study was designed to evaluate the efficacy of oral or metered dose inhaler (MDI) salbutamol using a coffee cup as a spacer device in bronchiolitis. In the trial, 31 hospitalized patients between 6 and 24 months of age, who exhibited the first episode of acute bronchiolitis without any other predisposing illness such as cystic fibrosis, congenital heart disease etc., were randomly assigned to receive oral salbutamol (n=11, 0.1 mg/kg per dose, four times a day), or MDI salbutamol (n = 12, 200 μg per dose, every 3 h) or formed the control group without any bronchodilator therapy (n = 8). All of the patients were given supplemental oxygen as needed and adequate hydration was maintained. The patients were evaluated with clinical symptom scores. There were no differences in the beneficial or side effects of salbutamol, or the number of days in hospital between the treatment groups and the control group. It was concluded that there is no beneficial effect in using bronchodilators in infants with bronchiolitis. Supplemental oxygen and maintenance of normal hydration may be adequate. 相似文献

OBJECTIVE: To study the efficacy of intravenous magnesium sulfate and intravenous salbutamol in the treatment of severe asthma in children. METHODS: Randomized, double-blind, placebo-controlled clinical trial, including children above 2 years of age with severe acute asthma admitted to the observation ward of the Pediatric Intensive Care Unit of Hospital S?o Lucas. All patients received conventional treatment (oxygen, corticoids, beta-adrenergics) on admission, and later received one of the following solutions: a) IVMg (50 mg/kg); b) intravenous salbutamol (1 micro g/kg); c) saline solution. Clinical assessments, electrolyte concentration, and arterial blood gas analyses were recorded before intravenous infusion and one hour after that. RESULTS: Fifty patients participated in this study (of whom 53% were females, mean age = 4.5 years). There were no significant differences among the three groups. The group that received IVMg presented lower blood pressure during administration, which reached normal levels one hour afterwards, along with an increase in serum magnesium (P<0,001) and serum pH, and reduction of PaCO(2). The group that received intravenous salbutamol had lower respiratory rate (P=0.05) and higher blood pressure (P=0.01), and one hour after administration, these patients showed decreased respiratory rate (P=0.02); lower levels of serum potassium (P=0.009); higher pH, and reduced PaCO(2). This group required fewer nebulizations (P=0.009), fewer nebulizations per day (P<0.001) and less oxygen therapy than the IVMg and placebo groups. Acidosis was more persistent (P<0.01) in the placebo group. No difference as to the length of hospital stay was observed in any of the three groups. Artificial ventilation was necessary in 10% of the patients. CONCLUSIONS: The early intravenous administration of magnesium sulfate, especially salbutamol, achieved a rapid clinical response with excellent prognosis and no significant side effects. 相似文献
