Intervention Type: Other
Study Type: Observational
SUMMARY
This observational study aims to compare the postoperative analgesic effectiveness of ultrasound-guided transversus abdominis plane (TAP) block and single-dose epidural anesthesia in patients undergoing umbilical hernia surgery. Pain intensity will be assessed using the Visual Analog Scale (VAS) at predefined postoperative time points. The study seeks to determine which analgesic approach provides superior pain control and patient satisfaction in the postoperative period.

Treatments
Group Transversus Abdominis Plane Block
Patients in this group will undergo umbilical hernia surgery under general anesthesia. Following completion of the surgical procedure, postoperative analgesia will be provided using an ultrasound-guided transversus abdominis plane (TAP) block, performed according to routine clinical practice. The TAP block will be administered by an experienced anesthesiologist using standard techniques and local anesthetic agents. No additional interventions or investigational medications will be applied as part of the study.~Postoperative pain intensity will be assessed using the Visual Analog Scale (VAS) at admission to and discharge from the post-anesthesia care unit, as well as at the 1st, 6th, 12th, and 24th postoperative hours. Rescue analgesia will be administered based on routine institutional protocols according to patient-reported pain scores.
Group Single Dose Epidural Anesthesia
Patients in this group will undergo umbilical hernia surgery under single-dose epidural anesthesia administered as part of routine clinical practice. The epidural technique will be performed by an experienced anesthesiologist using standard institutional protocols. The single-dose epidural injection will be used to provide both intraoperative anesthesia and postoperative analgesia. No additional interventions or investigational medications will be administered for the purpose of this study.~Postoperative pain intensity will be evaluated using the Visual Analog Scale (VAS) at admission to and discharge from the post-anesthesia care unit, as well as at the 1st, 6th, 12th, and 24th postoperative hours. Rescue analgesic treatment will be provided according to routine postoperative pain management protocols based on patient-reported pain scores.
