A clinical study of effect of peri-tonsillar infiltration of ropivacaine on tonsillectomy haemorrhage

Abstract

<p><strong>Background:</strong> The aim of this study to determine the relationship between the peritonsillar infiltration of ropivacaine hydrochloride and haemorrhage in patients undergoing tonsillectomy.</p><p><strong>Methods </strong>This prospective study was conducted in the department of otorhinolaryngology and head and neck surgery, Adichunchanagiri institute of medical sciences, B. G. Nagara, Mandya district. A sample size of 30 patients which satisfied the inclusion criteria were included in the study. <strong></strong></p><p>Ropivacaine (0.75%)<strong> </strong>was locally infiltrated on the right side (R-side) in the peri-tonsillar region before the surgery. The left side was considered as the control side. Intra-operative blood loss was estimated separately for both the sides. The data from the study will be analysed using chi square test and Student t test technique.</p><p><strong>Results:</strong> The 17 (56.7%) females and 13 (43.3%) males participated in the study. Majority of the cases belonged to <10 years of age group. By analysing the data, blood loss was found to be higher on the left side (control side) compared to the right side on which peri-tonsillar infiltration of ropivacaine was given. The association between the blood loss on the right side and the left side (control side) was found to be significant (p<0.0001).<strong></strong></p><p><strong>Conclusions: </strong>Based on the result of our study it can be derived that the peri-tonsillar infiltration of Ropivacaine (0.75%) is very effective in reducing intra-operative bleeding and at the same time providing a better bloodless field during surgery. Hence, we recommend the use of peri-tonsillar infiltration of Ropivacaine (0.75%) in view of better management of intra-operative blood lossissn.2454-5929.ijohns20220041</p>
