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

Background The aim of this study to determine the relationship between the peritonsillar infiltration of ropivacaine hydrochloride and haemorrhage in patients undergoing tonsillectomy.Methods 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. Ropivacaine (0.75%) 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.

Results 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).

Conclusions 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
