Trial Outcomes & Findings for Efficacy of Nebulised Hypertonic Saline (3%) Among Children With Bronchiolitis. (NCT NCT01276821)

NCT ID: NCT01276821

Last Updated: 2013-05-31

Results Overview

Mean changes in the Clinical Severity Score after 2 sessions of nebulisation as compared to baseline. Clinical Severity Score devised by Wang et al, is an objective scoring system that measures the degree of respiratory distress in young children. The scoring system assesses respiratory rate, wheezing, retraction, and general condition,scores ranging from 0 to 3, with higher scores indicating severe illness and vice versa. The total scores range from 0 to 12, with increased severity receiving a higher score (Wang et al, 1992). This scoring systems have previously been validated in a number of well designed randomized controlled trials(Anil 2010, Kuzik 2007, Sarrell 2002, and Mandelberg 2003). A 1 point improvement in the clinical severity score implies approximately 7% betterment of symptoms on the scale.

Participant Flow

Subjects were recruited from previously healthy children aged 6 weeks to 24 months with first episode of wheezing who visited the OPD and ER of Kanti Children Hospital and met the clinical definition of bronchiolitis. Recruitment occurred on weekdays from 8:00 to 17:00 Hours. Out of 754 screened children, 159 were first episode wheezers.

The outcomes tries to compare the influence of duration of crying among babies receiving nebulization which interferes with drug delivery and henceforth might create a confounding bias while interpreting results.
