标题：Relationship between oxygen saturation and clinical symptoms or signs in infants from 2 months to 12 months age with acute respiratory distress due to hyper reactive airway disease
摘要：Background : Facilities to measure SPO2 are not available at all centers especially in the resource poor developing countries.This study is therefore important to identify a minimumset of clinical signs that can reliably predict presence of hypoxemia in children with hyperreactive airnway disease that can be used by health care provider to institute oxygen therapy.Methods : study was carried out as a single centre,prospective,observational study from year 2005 to 2007.A total of 51 children were studied equally divided in three groups depending upon oxygen saturation.A clinical scoring system was used which was generated after reviewing many studies and taking more practical aspect in relation to its use in peripheral set up.Result : The average age of the infants with oxygen saturation > 95% (Group A),90-95%.(Group B) and <90% ( Group C) was 7.82,8.02 and 8.17 months respectively.It was observed that clinical score for group A ( SpO2 >95%) was ranging between 1 to 6,for group B (90 - 95%) was between 6 to 11 and for group C ( <90%) was between 8 to 13.Median score for patients with Sp02> 95% was 3,with Sp0290- 95% was 8 and with Sp02 <90% was 11 (Table 2).Correlation coefficient was -0.906,as axygen saturation was inversely related to clinical scoring of respiratory distress.Confidence interval at 95% for group A was 3.235+0.815,for group B was 8土0.672 andfor group C was 10.882土0.917 The difference of clinical score between group A,group B and group C were statistically significant (p<0.00I).Conclusion : Oxygen can be started for all babies with hyperreactive airway disease who are having clinical score of 7 or more and amount of oxygen to be increased as score increases from 7to 14.
