Clinical Trial Summary

Multimodal analgesia is used to control postoperative pain in inguinal hernia repair. Transversus abdominis plane block is an effective regional anesthesia technique for postoperative analgesia in inguinal hernia repairs. The erector spinae plane block applied to thelow thoracic region was also reported to provide effective analgesia in these surgeries. In this study, we aimed to determine and compare the effects of transversus abdominis plane block and lumbar erector spinae plane block on postoperative pain in inguinal hernia repairs.

Intervention

Procedure:
• ESP Block
ESP block will be performed at the finishing of surgery under spinal anesthesia. A convex ultrasound transducer will be placed in a longitudinal parasagittal orientation 2-3 cm lateral to T10 spinous process. The erector spinae muscles will be identified superficial to the tip of T10 transverse process. The patient's skin will be anesthetized with 2% lidocaine. A 22-gauge 10-cm needle will be inserted using an out-plane superior-to-inferior approach to place the tip into the fascial plane on the deep (anterior) aspect of erector spinae muscle. The location of the needle tip will be confirmed by visible fluid spread lifting erector spinae muscle off the bony shadow of the transverse process. A total of 30 mL of bupivacaine/lidocaine mixture will be injected.
• TAP Block
TAP block will be performed at the finishing of surgery under spinal anesthesia. A linear ultrasound transducer will be placed to lateral aspect of abdomen. A 22-gauge 10-cm needle will be inserted using an out-plane superior-to-inferior approach to place the tip into the fascial plane between transversus abdominis and internal oblique muscles..A total of 30 mL of bupivacaine/lidocaine mixture will be injected.

Other:
• Standard Pain Followup and Monitorization
Numeric Rating Scale (NRS) pain score will be recorded and followed by 0., 1.-3.-6.-12.-18.-24.hours. it is planned that the patient will continue to follow the hourly NRS score in ward. Intramuscular diclofenac will be administered in this period if NRS 4 and if it is over, intravenous 0.5 mg / kg meperidine will be administered if NRS score is 4 or more after 2 hours. Salvage analgesic needs and times will be noted in detail, and the use of rescue analgesics, as well as NRS scores at designated hours, will be kept in a statistical evaluation.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Numeric Rating Scale	The numeric rating scale (NRS), the reference measurement method, will be used to determine the postoperative pain levels of the patients. Changes in NRS at rest and on movement will be recorded at intervals. NRS is a unidimensional measure of pain intensity in adults in which a respondent selects a whole number (0-10 integers) that best reflects the intensity of his/her pain. The 11-point numeric scale ranges from '0' representing one pain extreme (e.g. "no pain") to '10' representing the other pain extreme (e.g. "pain as bad as you can imagine" or "worst pain imaginable").	24 hours
Secondary	Tramadol consumption	Postoperative analgesia plan includes patient-controlled analgesia. Patient-controlled analgesia is a self-administered analgesic and a safe interval is programmed by a patient. Patients in all groups will be assessed at the end of 24 hours for tramadol consumed in patient-controlled analgesia devices.The electronic program in patient-controlled analgesia device can determine the amount of time the patient has applied the medication. The instrument's tool will be used for measurements.	24 hours
