Spinal Nerves: Plexus I01:22

Spinal Nerves: Plexus I

1.8K
Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.
The Cervical Plexus
The cervical plexus, formed by the anterior rami of the first four...

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia01:16

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia

843
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.
One of the advantages of...

Peripheral Nervous System: Ganglia and Nerves01:24

Peripheral Nervous System: Ganglia and Nerves

3.9K
The Peripheral Nervous System (PNS) is a crucial component of the body's neural network, extending beyond the central nervous system (CNS) to bridge the gap between the CNS and the external environment. It encompasses nerves, ganglia, and sensory receptors.
Nerves
The nerve is a bundle of axons that serves as the communication highway in the PNS. Each nerve is ensheathed in a protective layer of connective tissue called the epineurium. This outermost layer safeguards the nerve and supports the...

Local Anesthetics: Differential Sensitivity of Nerve Fibers01:24

Local Anesthetics: Differential Sensitivity of Nerve Fibers

1.2K
Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...

Nondepolarizing (Competitive) Neuromuscular Blockers: Mechanism of Action01:17

Nondepolarizing (Competitive) Neuromuscular Blockers: Mechanism of Action

2.5K
Nondepolarizing neuromuscular blockers induce paralysis by competitively blocking nicotinic acetylcholine receptors at the muscle end plate. Examples include pancuronium, mivacurium, vecuronium, and rocuronium. These quaternary ammonium derivatives are administered intravenously, are poorly absorbed, and are excreted via the kidneys.
Competitive antagonists prevent acetylcholine from binding to its receptor, inhibiting membrane depolarization. Without conformational changes or intrinsic...

Sympathetic Pathways: Sympathetic Chain Ganglia01:20

Sympathetic Pathways: Sympathetic Chain Ganglia

4.5K
The sympathetic chain ganglia, also known as the sympathetic trunk ganglia or paravertebral ganglia, are a series of ganglia located bilaterally on either side of the spinal column. These ganglia serve as relay stations for the sympathetic nervous system. Preganglionic neurons originating in the spinal cord project their axons to the sympathetic chain ganglia. Within the ganglia, these preganglionic fibers synapse with postganglionic neurons.The postganglionic neurons of the sympathetic trunk...

Summary
This summary is machine-generated.

The pericapsular nerve group (PENG) block is an ultrasound-guided technique for hip pain relief. While promising for hip fracture analgesia, high-quality trials are needed to confirm its efficacy and role.

Area of Science:

  • Ultrasound-guided regional anesthesia
  • Pain management
  • Anesthesiology

Background:

  • The pericapsular nerve group (PENG) block is a novel ultrasound-guided technique.
  • Initially described for acute hip fracture pain, its indications have expanded.
  • Understanding its anatomical basis, technique, and effects is crucial.

Purpose of the Study:

  • To review existing literature on the PENG block.
  • To summarize anatomical considerations.
  • To provide an updated description of the technique, applications, and outcomes.

Main Methods:

  • A narrative review of medical literature databases (PubMed, Google Scholar, EMBASE, Web of Science) up to August 31, 2020.
  • Collection and synthesis of data on anatomy, indications, drugs, and technique.
  • Selection of 57 relevant publications.

Main Results:

  • The primary indication for the PENG block is hip-related analgesia.
  • A 20ml long-acting local anesthetic is commonly used.
  • No major complications like hematoma or organ injury were reported, though some femoral and obturator nerve blocks occurred.

Conclusions:

  • The PENG block demonstrates significant promise as an analgesic technique.
  • Further high-quality randomized controlled trials are necessary to establish its definitive role.
  • The technique appears safe based on current case reports and series.
