ObjectivesTo compare the response between different doses of nebulized magnesium sulphate along with Salbutamol in children between two to 12 years of age with status asthmaticus.MethodsThis single blinded, randomized clinical trial was carried out at the Department of Pediatrics, Dr. Ziauddin University Hospital, Karachi, Pakistan during October 2021 to September 2022. A total of 104 children aged between 2-12 years, with the diagnosis of asthma having "Pediatric Rapid Assessment Measure (PRAM)" score>4 and with reactive airways were included. Children either received three back-to-back nebulization with salbutamol solution only (n=50) or salbutamol and MgSO4 with three different doses (250mg, 500mg or 750mg) after every 20 minutes for 60 minutes. The PRAM score was used as an assessment tool to clinically score asthma.ResultsIn a total of 104 children, 53 (51.0%) were girls. The mean age was 5.25±2.86 years. No statistically significant difference was found in PRAM scores at baseline (p=0.448) and at 20-minutes (p=0.072) but significant differences were observed at 40-minutes (p=0.009), 60-minutes (p=0.011), 120-minutes (p=0.010), 6-hours (=0.034), 12-hours (p=0.018), 18-hours (p=0.033) and at 24-hours (p=0.029). The reduction in PRAM scores from baseline to 24-hours following treatment among Salbutamol, Salbutamol+ MgSo4 250mg, Salbutamol+ MgSo4 500mg and Salbutamol+ MgSo4 750mg group were 6.53±1.09, 7.22±1.09, 6.85±1.43 and 7.57±1.06 respectively (p=0.007).ConclusionWhile children with status asthmaticus managed using salbutamol, with or without nebulized MgSO4, showed improved clinical outcomes, combining salbutamol with higher dosages of nebulized MgSO4 resulted in even greater clinical improvement.Clinical Trial Registry: https://clinicaltrials.gov/ct2/show/NCT04929626.Copyright: © Pakistan Journal of Medical Sciences.
