Summary
This study validated a new questionnaire to assess practices in plexus and peripheral nerve blocks (PNBs). The validated tool can now be used to study PNB trends and disparities.
Area of Science:
- Anesthesiology and Perioperative Medicine
- Regional Anesthesia Techniques
Background:
- Limited data exists on the current usage and practices of plexus and peripheral nerve blocks (PNBs).
- Regional anesthesia impacts perioperative and long-term patient outcomes.
- There is a need for standardized tools to survey PNB practices.
Purpose of the Study:
- To develop and validate a survey questionnaire for assessing plexus and peripheral nerve blocks (PNBs) practices.
- To establish a reliable instrument for future studies on PNB trends and disparities.
- To lay the groundwork for a potential national registry of PNB practices.
Main Methods:
- A 30-question survey was developed based on evidence-based searches and expert review.
- The questionnaire and grading sheet were sent to 19 experts for assessment.
- Content Validity Index (CVI) and modified kappa statistics were used to analyze expert responses.
Main Results:
- Fourteen experts provided feedback, leading to question refinement and format adjustments.
- The questionnaire achieved high item-wise CVI (I-CVI) scores for relevance (0.99), simplicity (0.98), clarity (0.98), and ambiguity (0.99).
- Scale-wise CVI (S-CVI/average) scores were also excellent, ranging from 0.97 to 0.99 across all metrics.
Conclusions:
- The developed questionnaire meets content validity criteria for studying plexus and peripheral nerve blocks (PNBs).
- This validated instrument can be utilized to investigate current PNB practices.
- The tool supports future research into PNB trends and potential disparities.

1.1K
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...

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 plexuses of the lower body include the lumbar, sacral, and coccygeal plexuses, which innervate the abdomen, pelvis, legs, and coccygeal region. These plexuses control the transmission of sensory information and coordinate motor functions of the lower body.
The Lumbar Plexus
The lumbar plexus is situated within the lumbar region of the back and is primarily formed by the first four lumbar spinal nerves (L1 to L4). This plexus extends its branches into several nerves, including the...

01:16Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
795
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.

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...
