About this study
Official title: Comparison of the Analgesic Efficacy of Ultrasound-guided Transversus Abdominis Plane Block and Single-dose Epidural Block in Patients Undergoing Umbilical Hernia Surgery.
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.
Read the detailed description
Postoperative pain management plays a critical role in reducing the adverse consequences of surgery, facilitating early mobilization, enhancing patient comfort, and promoting rapid recovery and discharge. Epidural analgesia is widely regarded as the gold standard for postoperative pain control due to its strong analgesic efficacy and its ability to reduce the need for additional anesthetic and analgesic agents. However, peripheral and fascial plane blocks such as the transversus abdominis plane (TAP) block have gained increasing popularity because of their opioid-sparing effects and favorable side-effect profiles.
The transversus abdominis plane is a neurofascial plane located between the internal oblique and transversus abdominis muscles and provides somatic analgesia to the anterolateral abdominal wall by blocking the thoracolumbar nerves from T9 to L1. Previous studies have demonstrated that TAP block is associated with reduced postoperative pain scores, decreased opioid consumption, and fewer opioid-related adverse effects.
This study is designed as an observational comparison of two routinely applied analgesic strategies in patients undergoing umbilical hernia surgery. Patients aged between 18 and 65 years, classified as American Society of Anesthesiologists (ASA) physical status I or II, will be included. Depending on the anesthesiologist's clinical judgment and routine practice, patients undergo surgery either under single-dose epidural anesthesia or under general anesthesia followed by postoperative ultrasound-guided TAP block for analgesia.
No additional interventions or medications will be administered for the purpose of this study. Data collection will begin once patients are admitted to the postoperative recovery unit. Postoperative pain intensity will be assessed using the Visual Analog Scale (VAS) at recovery room admission and discharge, as well as at the 1st, 6th, 12th, and 24th postoperative hours. Rescue analgesia will be administered according to routine clinical protocols based on patients' reported pain levels.
The primary objective of this study is to compare the analgesic effectiveness of single-dose epidural anesthesia and TAP block in umbilical hernia surgery. Secondary objectives include the evaluation of patient satisfaction and the identification of the most effective postoperative analgesic approach within routine clinical practice. As all procedures involved are part of standard care, this study does not constitute an interventional drug trial but rather an observational assessment of established analgesic techniques.

What is being measured
The primary outcome is the main question the study is designed to answer.
Visuel Analog Scale 6th hour
Postoperative pain intensity will be evaluated using the Visual Analog Scale (VAS) at the 6th postoperative hour to compare the analgesic effectiveness of single-dose epidural anesthesia and ultrasound-guided transversus abdominis plane (TAP) block. The Visual Analog Scale (VAS) is used to assess pain intensity on a numeric scale ranging from 0 to 10, where 0 indicates no pain and 10 indicates the worst pain imaginable. Patients are asked to select the number that best represents their current level of pain at the time of assessment. Increasing scores reflect increasing pain severity, with values of 1-3 considered mild pain, 4-6 moderate pain, and 7-10 severe pain. The VAS is a simple, reliable, and sensitive tool for detecting changes in pain intensity over time and is widely used in clinical trials and postoperative pain assessment.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.
Detailed description
Postoperative pain management plays a critical role in reducing the adverse consequences of surgery, facilitating early mobilization, enhancing patient comfort, and promoting rapid recovery and discharge. Epidural analgesia is widely regarded as the gold standard for postoperative pain control due to its strong analgesic efficacy and its ability to reduce the need for additional anesthetic and analgesic agents. However, peripheral and fascial plane blocks such as the transversus abdominis plane (TAP) block have gained increasing popularity because of their opioid-sparing effects and favorable side-effect profiles.
The transversus abdominis plane is a neurofascial plane located between the internal oblique and transversus abdominis muscles and provides somatic analgesia to the anterolateral abdominal wall by blocking the thoracolumbar nerves from T9 to L1. Previous studies have demonstrated that TAP block is associated with reduced postoperative pain scores, decreased opioid consumption, and fewer opioid-related adverse effects.
This study is designed as an observational comparison of two routinely applied analgesic strategies in patients undergoing umbilical hernia surgery. Patients aged between 18 and 65 years, classified as American Society of Anesthesiologists (ASA) physical status I or II, will be included. Depending on the anesthesiologist's clinical judgment and routine practice, patients undergo surgery either under single-dose epidural anesthesia or under general anesthesia followed by postoperative ultrasound-guided TAP block for analgesia.
No additional interventions or medications will be administered for the purpose of this study. Data collection will begin once patients are admitted to the postoperative recovery unit. Postoperative pain intensity will be assessed using the Visual Analog Scale (VAS) at recovery room admission and discharge, as well as at the 1st, 6th, 12th, and 24th postoperative hours. Rescue analgesia will be administered according to routine clinical protocols based on patients' reported pain levels.
The primary objective of this study is to compare the analgesic effectiveness of single-dose epidural anesthesia and TAP block in umbilical hernia surgery. Secondary objectives include the evaluation of patient satisfaction and the identification of the most effective postoperative analgesic approach within routine clinical practice. As all procedures involved are part of standard care, this study does not constitute an interventional drug trial but rather an observational assessment of established analgesic techniques.
