Abstract:
The infraclavicular approach to the brachial plexus is a safe and reliable technique for surgery of the upper extremity. When performing the block, the anesthesiologist must appreciate three variables: needle direction, needle angle to the chest wall, and needle depth. Surface stimulation is an easy technique that can reliably predict both needle direction and needle angle.

Assessing Body Temperature - Axilla
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...

Assessment of apical pulse
Assessing the apical pulse is a critical nursing procedure, particularly indicated for:
Assessment of blood pressure in brachial artery(one-step method)
Prepare for the Procedure:
Assessment of the Abdomen III: Palpation
Assessment of apical radial pulse
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
