Summary
Post-hip surgery pain is common. A new iliopsoas plane block (IPB) may reduce hip pain after total hip arthroplasty (THA) without causing leg weakness, unlike other regional blocks.
Area of Science:
- Anesthesiology
- Orthopedic Surgery
- Pain Management
Background:
- Moderate to severe pain affects many patients post-total hip arthroplasty (THA).
- Opioid use for post-THA pain carries risks.
- Current regional analgesia techniques for hip pain are complex due to multi-nerve innervation.
Purpose of the Study:
- To investigate the efficacy of a novel iliopsoas plane block (IPB) for post-THA pain relief.
- To evaluate the IPB's potential to target hip articular sensory branches of the femoral nerve.
- To assess if the IPB avoids motor blockade, unlike femoral nerve blocks.
Main Methods:
- The study focuses on the development and proposed application of the iliopsoas plane block (IPB).
- The primary innervation of hip joint nociceptors by obturator and femoral nerves is considered.
- Comparison is made with existing obturator nerve block (ONB) and femoral nerve block (FNB) approaches.
Main Results:
- The iliopsoas plane block (IPB) is a novel technique designed for hip analgesia.
- The IPB aims to provide anesthesia to hip articular sensory branches.
- This technique is hypothesized to avoid motor deficits associated with femoral nerve blocks.
Conclusions:
- The iliopsoas plane block (IPB) presents a promising alternative for managing post-total hip arthroplasty (THA) pain.
- This technique may offer effective analgesia while minimizing the risk of falls associated with motor blockade.
- Further investigation into the obturator nerve block (ONB) and IPB for THA pain is warranted.

01:16Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
1.0K
Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.

01:11Local Anesthetics: Clinical Application as Spinal Anesthesia
1.2K
Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...

Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

1.4K
Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

01:30Local Anesthetics: Clinical Application as Surface, Infiltration, and Conduction Block Anesthesia
1.7K
Depending on the target organ, local anesthetics (LAs) can be administered via various routes. In surface anesthesia, LAs are applied directly to the surface of the skin or mucous membranes. It is widely used for topical skin numbing before venipuncture or minor surgical procedures. Commonly used surface local anesthetics are lidocaine or benzocaine sprays or creams. Surface anesthesia occurs within 5 minutes and lasts for about 60 minutes. One of the main disadvantages of topical anesthesia is...
