Ultrasound-Guided Transversus Abdominis Plane Block Versus Epidural Block for Umbilical Hernia Analgesia

Comparison of the Analgesic Efficacy of Ultrasound-guided Transversus Abdominis Plane Block and Single-dose Epidural Block in Patients Undergoing Umbilical Hernia Surgery.

Sponsor

Study Type

OBSERVATIONAL

Conditions

Umbilical hernia Postoperative Pain Management

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.

Eligibility

Min Age: 18 YearsMax Age: 65 Years

Inclusion Criteria6

Patients aged 18 to 65 years

Patients who undergo surgery under either: Single-dose epidural anesthesia, or general anesthesia with postoperative ultrasound-guided transversus abdominis plane (TAP) block, as part of routine clinical practice
Ability to understand and use the Visual Analog Scale (VAS)
Provision of written informed consent

Exclusion Criteria10

ASA physical status III or higher
Known allergy or contraindication to local anesthetic agents
Coagulopathy or ongoing anticoagulant/antiplatelet therapy contraindicating regional anesthesia
Infection at the site of epidural or TAP block application
History of chronic pain, long-term opioid use, or chronic analgesic consumption
Neurological disorders affecting pain perception or assessment
Severe hepatic or renal disease
Pregnancy or lactation
Inability to cooperate with postoperative pain assessment or inability to use VAS
Emergency surgery

Interventions

OTHERUltrasound-Guided Transversus Abdominis Plane Block

Ultrasound-guided transversus abdominis plane (TAP) block is performed as part of routine postoperative analgesia following general anesthesia in patients undergoing umbilical hernia surgery. The procedure is administered by an experienced anesthesiologist using standard institutional practice. No additional procedures or medications are applied specifically for the purpose of this observational study.

OTHERSingle-Dose Epidural Anesthesia

Single-dose epidural anesthesia is administered as part of routine clinical practice to provide intraoperative anesthesia and postoperative analgesia in patients undergoing umbilical hernia surgery. The technique is performed by an experienced anesthesiologist according to standard institutional protocols. No investigational interventions or study-specific modifications are implemented.
