Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Inguinal Hernia Surgery (Group T)

Half of the study participants named Group T were administered Ultrasound Guided Transversus Abdominis Plane Nerve Block and the other half named Group I were administered Ilioinguinal \& Iliohypogastric Nerve Block before the Inguinal Hernia Surgery.

Group Type EXPERIMENTAL

Transversus abdominis plane (TAP) block with 0.25 % bupivacaine

Intervention Type DRUG

The probe was placed in a plane transverse to the lateral abdominal wall in the mid-axillary line immediately cephalad to the iliac crest. The needle was advanced immediately anterior to the probe using the in-plane needle-probe orientation and advanced posteriorly until the needle was observed to penetrate the interface between the internal oblique and transversus abdominis muscles. Thereafter, a local anesthetic (0.2 mL/kg of 0.25 % bupivacaine) was injected incrementally, and the spread was observed within the plane.

Inguinal Hernia Surgery (Group I)

Half of the study participants named Group T were administered Ultrasound Guided Transversus Abdominis Plane Nerve Block and the other half named Group I were administered Ilioinguinal \& Iliohypogastric Nerve Block before the Inguinal Hernia Surgery.

Group Type EXPERIMENTAL

Ilioinguinal/iliohypogastric Nerve Block with 0.25 % bupivacaine

Intervention Type DRUG

The ultrasound probe was placed immediately medial and slightly cephalad to the upper aspect of the anterior superior iliac spine to obtain a short-axis view of the nerves situated between the two abdominal muscles (internal oblique and transversus abdominis), A 22 G needle tip \~1 cm caudal to the probe surface was introduced and was advanced until a characteristic 'tenting' of the interface between the two muscles was seen and was then further advanced deep to this interface until a pop was felt and then the injectate (0.2 mL/kg of 0.25 % bupivacaine) was observed spreading between these two layers.
