Abstract:
The author describes the use of ultrasound to facilitate a continuous infraclavicular brachial plexus block in a patient who had been anticoagulated with 5000 U of heparin. The procedure was done 2 h after the patient was anticoagulated, and his activated clotting time was 203 s. The patient had vascular checks with a laser Doppler monitor every hour and neurological checks every 12 h.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
