Summary
Adding transpectoral sonography significantly improves the success rate of perivascular axillary plexus blocks. This ultrasound-guided technique enhances block effectiveness and efficiency, reducing the need for general anesthesia.
Area of Science:
- Anesthesiology
- Regional Anesthesia
- Ultrasound Guidance
Background:
- Perivascular axillary plexus block is simple but has a high failure rate.
- Ultrasound (US) guidance can potentially improve block success.
- Transpectoral sonography offers advantages with minimal technique alteration.
Purpose of the Study:
- To evaluate the efficacy of transpectoral sonography in perivascular axillary plexus blocks.
- To compare success rates with and without ultrasound guidance.
- To assess the impact on procedure time and need for general anesthesia.
Main Methods:
- A novel technique combining perivascular axillary plexus block with transpectoral sonography was developed.
- The study included 86 patients.
- Success rates and time factors were recorded and compared to historical data.
Main Results:
- Ultrasound-guided blocks achieved a 96.5% success rate, compared to 72% without US.
- No patients required general anesthesia when using transpectoral sonography.
- The average onset time for US-guided blocks was approximately 6 minutes.
Conclusions:
- Transpectoral sonography significantly increases the success rate of perivascular axillary plexus blocks.
- The combined technique is effective and efficient, improving patient outcomes.
- Ultrasound guidance is recommended for perivascular axillary plexus blocks.

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

01:22Spinal Nerves: Plexus I
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.

Assessment of Radial Pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:

Procedural Guide for Assessing Axillary Body Temperature using a Digital Thermometer:
Step 1: Perform hand hygiene and put on clean gloves to maintain infection control and prevent cross-contamination.
Step 2: Prepare the patient by explaining the procedure to ensure understanding and cooperation. Ensure privacy, expose the axilla, and inform the patient that minimal movement is crucial for an accurate reading.
Step 3: Adjust the patient’s clothing to expose only the axilla. It minimizes...

01:12Arteries of the Upper Limbs
The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...
01:21Sites for measuring blood pressure
Blood pressure measurement is a fundamental clinical procedure, providing crucial data for assessing cardiovascular health. Among the various sites for this measurement, the brachial and popliteal arteries are predominantly utilized due to their accessibility and the reliability of their readings. This lesson delves into the anatomical significance, methodology, and considerations of measuring blood pressure at these locations.
