The Effect of Adjuvant Local Anaesthesia on Post-Operative Outcomes in Inguinal Hernioplasty: A Randomized Controlled Study
The results of the analysis of data on 62 patients who underwent hernioplasty with and without adjuvant ropivacaine infiltration are as follows: The mean age of the patients in both the study group and the control group was 38 years. The incidence of indirect inguinal hernia was high compared to direct hernia in both the groups. In study group, 24 (77.4%) patients had indirect inguinal hernia and 7 (22.6%) patients had direct hernia. In control group, 28 (90.3%) patients had indirect inguinal hernia and 3 (9.7%) patients had direct inguinal hernia. In our study, all patients in both the groups were male with 100% preponderance incidence of indirect and direct inguinal hernia. In both the groups, the incidence of indirect inguinal hernia was high. In study group, 24 patients had indirect inguinal hernia and 7 patients had direct inguinal hernia. In control group, 28 patients had indirect inguinal hernia and 3 patients had direct inguinal hernia. The incidence of indirect inguinal hernia was common in the age group of 21 to 45 years in study group and 22 to 49 years in control group. Around 16 patients in study group had left sided hernia and 10 patients in control group, had left sided hernia. Therefore, right sided hernia was more common among the study groups. Pain was measured using visual analogue scoring and a score of more than 5 was taken as significant. Patients under study group was comfortable without pain up to >5 h when compared to patients in control group who required early analgesic dose post-operatively with a significant p-value (p<0.001). Post operatively analgesics (intravenous paracetamol) were given on demand to patients who complained of pain. Pain was measured using visual analogue scoring and a score of more than 5 was taken as significant. Patients who were given adjuvant ropivacaine infiltration had lesser post-operative pain as compared to those did not have adjuvant local anaesthetic infiltration. This study showed significant difference between the two groups in post-operative pain (p-value <0.050) (Graph 1).
