Introduction:

The PENG (Psoas Compartment, Femoral Nerve, and Genitofemoral Nerve) regional block is a nerve block technique used for providing analgesia to the hip and groin region. It targets the nerves involved in innervating these areas, offering effective pain relief for various surgical procedures and postoperative management. This article aims to provide an overview of the PENG regional block, including the procedure, benefits, and important considerations.

Procedure of PENG Regional Block:

• Patient positioning: The patient is positioned in a supine or lateral decubitus position, depending on the preference of the healthcare provider.
• Ultrasound guidance: Ultrasound imaging is used to identify the anatomical structures, including the psoas muscle, femoral nerve, and genitofemoral nerve.
• Needle insertion: A needle is inserted under ultrasound guidance to deliver local anesthetic solution in proximity to the target nerves. The needle is advanced until it reaches the psoas muscle sheath, where the anesthetic is deposited.
• Local anesthetic administration: A mixture of local anesthetic, such as ropivacaine or lidocaine, is injected around the psoas muscle and adjacent nerves to block their transmission of pain signals.
• Confirmation of correct needle placement: The spread of local anesthetic is confirmed by observing its diffusion on ultrasound imaging.
• Catheter placement (optional): In some cases, a catheter may be inserted for continuous infusion of local anesthetic to prolong the duration of pain relief.

Benefits of PENG Regional Block:

• Effective analgesia: The PENG regional block provides effective pain relief in the hip and groin region, making it valuable for surgical procedures, such as hip joint surgery or groin hernia repair.
• Reduced opioid use: By providing targeted analgesia, the PENG block can significantly reduce the need for opioid medications, minimizing the risk of opioid-related side effects and complications.
• Enhanced recovery: Improved pain control through the PENG block can contribute to enhanced recovery after surgery, allowing patients to mobilize earlier and participate actively in rehabilitation.
• Reduced postoperative complications: Effective pain management with the PENG block can help reduce postoperative complications associated with inadequate pain control, such as deep vein thrombosis, pneumonia, or urinary retention.

Considerations for PENG Regional Block:

• Expertise and training: Performing the PENG block requires expertise in ultrasound-guided nerve blocks. Proper training and experience are essential to ensure accurate needle placement and minimize the risk of complications.
• Patient selection: The suitability of a patient for the PENG block depends on factors such as the type of surgery, patient preference, and individual considerations. A thorough evaluation of the patient's medical history, allergies, and concurrent medications is necessary.
• Potential complications: While rare, complications associated with the PENG block may include infection, bleeding, nerve injury, or inadvertent injection into blood vessels. Proper sterile techniques and careful needle placement can help minimize these risks.

Conclusion:

The PENG regional block is a valuable technique for providing effective pain relief in the hip and groin region. With its benefits of improved analgesia, reduced opioid use, enhanced recovery, and reduced postoperative complications, the PENG block offers a valuable option for managing pain during and after surgical procedures. Proper expertise, patient selection, and attention to potential complications are essential for safe and successful PENG block administration.
