Management of asthma in Emergency. Department remains a challenge to all Emergency Physician and Allied Health Personnel. Various modality of treatment has surfaced since the last decade and lately, anaestheti~ medications have found a place in treatment of mild to moderate asthma patients. Anaesthetic medications have long been found to have direct effect on airway smooth muscle and it causes relaxation of the bronchial smooth muscles. The anaesthetic medication in question is Lignocaine. Lignocaine is an local anaesthetic and anti-arrythmic medication that is easily available. It has a rapid onset of action and short duration of action. Lately it has been found to have property to attenuate reflex bronchoconstriction and also anti-inflammatory. STUDY OBJECTIVE The objective of this study is to compare the result of relief of bronchoconstrictions in patients with acute asthma when they are given either combined nebulized lignocaine & salbutamol or salbutamol only. This study also would like to document the side effects of combined nebulized lignocaine and salbutamol. METHOD A prospective study was conducted on 50 patients who had come to the emergency department and required treatment for acute exacerbation of mild to moderate asthma. Patients who fulfilled the criterias for inclusion were randomized to receive either plain salbutamol or combined salbutamol with lignocaine nebulized treatment. Measurements of peak expiratory flow rate and other clinical datas such as blood pressure, pulse rate, respiratory rate and oxygen saturation level will be t*en in intervals. RESULTS The results from 50 patients requiring treatment for acute exacerbation of asthma showed that there were no significant difference between those randomized to receive plain salbutamol treatment and those receiving combined salbutamol and lignocaine nebulizers. At 15 minutes of treatment, the mean percentage of increased PEFR value of 20.92 ±2S.23 (Single) and IS.01 ± 22.09 (Combined) . The p value seen was 0.687 at 15 minutes interval of treatment. Even at 30 minutes of treatment shows the mean percentage value of increased PEFR at 33.91 ± 34.79 (Single) and 36.02 ± 41.15 (Combined) with p value of 0.846. Out of 25 patients who were given combined saJbutamoJ and lignocaine treatment, 16 patients experienced numbness of the oral cavity and 9 patients experienced both bitterness taste and numbmess of the oral cavity. CONCLUSION Combined salbutamol and lignocaine did not have a better relief of bronchoconstriction as compared to salbutamol nebulization in mild to moderate asthma. The expected side effects of lignocaine were encountered and there were no new ones.
