Random allocation for the intervention of the enrolled subjects will be done by closed, concealed allocation by the person not involved in the study, into three groups (Group A and Group B and group C) Group A : receiving 7 % hypertonic saline nebulization. Group B : receiving 3 % hypertonic saline nebulization. Group C : receiving 0.9 % normal saline nebulization. Single blinded study , only the investigator will be blinded. Clinical history, patient informed consent, physical examination, and study parameters as per case record format will be recorded for all enrolled subjects. Group A (n=32) will receive nebulization of 2.5 mL 7 % hypertonic saline(Cipla Hyperneb 7% Respules) Group B (n=32) will receive nebulization of 2.5 mL 3 % hypertonic saline(Cipla Hyperneb 3% Respules) Group C (n=32) will receive nebulization of 2.5 mL 0.9 % hypotonic saline. Upon admission Clinical Respiratory Severity Score will be calculated and the clinical severity will be assessed individually. The nebulization procedure will be performed upon admission and repeated every 6 hours until discharge. Subjects will be monitored for vital parameters (Heart Rate, SpO2, Respiratory Rate) and the data will be recorded in preset format as given in case report form. Physical examination of the subjects will be done every 12 hourly before the next dose of nebulization to calculate the Clinical Respiratory Severity Score, and the same will be charted and followed up. Clinical outcome will be correlated with improvement in Respiratory severity score. The subjects will be discontinued from nebulization, examination and assessment if a. CSS <4, SaO2>92% in room air for 4 hours and no feeding difficulty. b. Upon 5 days of nebulization completion. Length of stay will be calculated from the first dose of study medication until clinical decision to discontinue from the trail. All subjects will be monitored and assessed by using clinical respiratory severity score. Statistical Analysis of the recorded data will be conducted using appropriate methods.
*PURPOSE OF STUDY* To compare the efficacy of 7% , 3% and 0.9% saline nebulization in the management of moderate to severe bronchiolitis among children aged 1 to 24 months using CRSS score. To compare the clinical improvement ( length of stay in PICU and early recovery) between children receiving nebulization of 7 % hypertonic saline (HS), 3% HS and 0.9% Saline normal saline. To compare the cost effectiveness of 7 % and 3% Hypertonic saline Nebulization in treatment of bronchiolitis. To study the adverse effect in children receiving 7% and 3% hypertonic saline nebulization. |
