The aim of this study is to compare laparoscopic -assisted, ultrasound-guided transversus abdominis plane block and laparoscopic intraperitoneal instillation of local anesthetic in pediatrics undergoing inguinal hernia repair.
Inguinal hernia is one of the most common pediatric surgeries. Effective and safe pain management causes fewer side effects and enables faster hospital discharge. It is also important in overcoming chronic pain in the late postoperative period.
Transversus abdominis plane block (TAPB) has emerged as a safe, simple, and inexpensive modality incorporated into many enhanced recovery pathways to achieve narcotic-sparing analgesia after bariatric surgery. TAPB was first performed through the lumbar triangle of Petit in 2001. Since that time, both ultrasound-guided (US) and laparoscopic (LAP) TAPBs have been developed to aid in proper identification of the correct plane and minimize peritoneal penetration.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Ultrasound-guided transversus abdominis plane block | Active Comparator | This group will receive Ultrasound-guided transversus abdominis plane block by using 1 ml/kg of bupivacaine 0.25% with a maximum volume of 20 mL as a control group. |
|
| Laparoscopic-assisted transversus abdominis plane block | Experimental | Patients will receive Laparoscopic-assisted transversus abdominis plane block by using 1 ml/kg of bupivacaine 0.25% with a maximum volume of 20 mL. |
|
| Laparoscopic-assisted intraperitoneal instillation | Experimental | This group will receive Laparoscopic-assisted intraperitoneal instillation by using 1 ml/kg of bupivacaine 0.25% with a maximum volume of 20 mL will be instilled into the peritoneal cavity immediately after gas insufflation. |

| Ultrasound-guided transversus abdominis plane block | Procedure | This group will receive ultrasound-guided transversus abdominis plane block by using 1 ml/kg of bupivacaine 0.25% with a maximum volume of 20 mL as a control group. |
| Measure | Description | Time Frame |
|---|---|---|
| Total postoperative pethidine consumption | The patient will be given supplementary paracetamol I.V. injection in a dose of 15 mg/kg as routine analgesia. If the FLACC score is > 3, pethidine 0.5 mg/kg. | 24 hours postoperatively |
| Measure | Description | Time Frame |
|---|---|---|
| Post-operative pain scores | Face, Legs, Activity, Cry and Consolability (FLACC) scale will be used for postoperative pain assessment. This scale ranges from 0 to 10 where 0 represents no pain and 10 represents worst possible pain. FLACC scale will be measured at 30 minutes and then at 2, 4, 6, 12, 18 and 24 hours. | 24 hours postoperatively |
