Journal Title: Bengal Journal of Otolaryngology and Head Neck Surgery - Year 2018, Vol 26, Issue 3
Abstract
Introduction It is a common practice to infiltrate 2% lignocaine with 1:2,00,000 adrenaline for Type 1 Tympanoplasty, even when the surgery is done under general anaesthesia. The purpose of this study is to evaluate the necessity of infiltration of lidocaine with adrenaline (2% lidocaine with 1:2,00,000 adrenaline) in Type 1 Tympanoplasty surgeries performed under general anaesthesia in terms of per-operative bleeding and post-operative pain relief. Materials and Methods A double blinded, prospective randomized comparative study was conducted in a tertiary care centre. A total of 50 patients planned for Type 1 Tympanoplasty under general anaesthesia, for chronic otitis media, inactive, mucosal disease were selected and divided into two groups randomly. Group A (25 patients) received local infiltration of 2% Lidocaine with 1:2,00,000 adrenaline and Group B (25 patients) patients received infiltration of sterile water. The per -operative bleeding and post-operative pain relief were assessedat 2nd, 4th and 6th post-operative hour in both the groups and the results were analysed. Results P value for per operative bleeding was <0.77 (non-significant). And the P value for post-operative pain relief at 2nd hour was <0.002 (significant). But the P value for 4th (<0.133) and 6th (<0.358) post-operative hours were not significant. ConclusionInfiltration of 2% lidocaine with 1:2,00,000 adrenaline, doesn’t have any significant impact in per-operative bleeding and post-operative pain relief at 4th and 6th hour. But there is a significant pain relief, for 2 hours after surgery, when 2% lidocaine with 1:2,00,000 adrenaline is used for infiltration.
