Brief Summary

To Compare two different concentrations of Ropivacaine 0.25% and 0.5%  for post operative analgesia in inguinal hernia repair.

 Randomisation will be performed using chit and box method and the patients will be divided into two groups.

**Group A**- 20ml of **0.25%**Ropivacaine subcutaneously,

**Group B**- 20ml of **0.5%**Ropivacaine subcutaneously

**SKIN INFILTRATION**: Study drug of 20ml Ropivacaine will be administered subcutaneously at the time of skin closure on both sides of incision by double blind technique.

•      After the surgery, the patients will be shifted to the recovery room and standard monitoring like ECG, NIBP, SpO2 will be attached **.**

•      Patients will be observed in the recovery room for 60min and will be assessed every 15 min. Postoperative Hemodynamic parameters- H.R, SPO2, SBP,DBP,MAP will be noted.

•      Postoperatively, the pain on rest, pain on coughing and pain on movements will be assessed using VAS score immediately after the surgery and then every 2 hours to 12 hours.

•      The time of first request for rescue analgesia will be noted and rescue analgesia will be provided with Inj.Tramadol 1mg/kg iv on demand or when VAS score more than 4. Total dose of rescue analgesia given in 12 hours will be recorded.

•      Side effects such as headache, nausea, vomiting, allergic reactions and convulsions will be looked for.

This prospective randomized clinical study compared Ropivacaine 0.25% and 0.5% for post-operative analgesia for the repair of inguinal hernia. There was an almost uniform distribution of the males and females among 2 groups. The mean age of the subjects in the 2 groups was 43.44±10.74 years and 41.63±11.55 years respectively.

No significant difference in heart rate, Systolic blood pressure, Diastolic blood pressure, Mean blood pressure and SpO2 between 2 groups. The mean VAS score (at Rest) at 8 hours was significantly more among GROUP A (0.50%) compared to GROUP B (0.25%). The mean VAS score (at Coughing) at 6, 8 and 10 hours was significantly more among GROUP B (0.25%) compared to GROUP A (0.50%). The mean VAS score (at movement) at 8, 10 and 12 hours was significantly more among GROUP B (0.25%) compared to GROUP A (0.50%).

Inguinal hernia surgery can be well undertaken in local infiltration technique. The field block technique meets all the requirements needed for the surgery, like adequate analgesia, enough relaxation, good haemodynamic stability, minimal side effects and in addition longer post-operative pain relief. It is the well suited technique for day care surgery. Ropivacaine 0.5% provided good quality  anesthesia for inguinal surgery compared to 0.25% Ropivacaine.

Ropivacaine as an anesthetic in ingui­nal hernia repair for elderly patients is safe and effective in pain reduction, with very few adverse reactions. Ropivacaine is optimally effective regarding heart rate reduction, arterial pressure, or perceived pain by patients at the concentration of 0.5% with least side effects.
