Anesthetic techniques: focus on transversus abdominis plane (TAP) blocks

Area of Science:

• Anesthesiology
• Surgical Pain Management
• Regional Anesthesia

Background:

• Transverse abdominis plane (TAP) blocks are increasingly utilized in multimodal analgesia.
• These blocks target the somatic pain component, demonstrating consistent benefits in early postoperative periods.
• Ultrasound guidance has significantly improved the safety and reliability of TAP block procedures.

Purpose of the Study:

• To review the applied anatomy crucial for performing TAP blocks and related techniques.
• To standardize the nomenclature for TAP blocks and their variations.
• To guide the selection of TAP block variants based on their safety and complication profiles.

Main Methods:

• Literature review focusing on applied anatomy of the abdominal wall.
• Analysis of studies evaluating TAP block efficacy and safety.
• Comparison of different TAP block approaches and their outcomes.

Main Results:

• TAP blocks provide significant pain reduction and decreased opioid consumption in the first 24-48 hours post-surgery.
• Ultrasound-guided TAP blocks are associated with improved safety and predictability.
• Understanding applied anatomy is key to successful execution and complication avoidance.

Conclusions:

• TAP blocks are a valuable component of postoperative pain management, particularly when guided by ultrasound.
• Standardized nomenclature and clear understanding of anatomical variations are essential for optimal clinical application.
• This review provides a framework for choosing appropriate TAP block techniques and managing potential complications.
