The sixth edition was noted for its illustrations of technical procedures such as ultrasound-guided peripheral venous access, caudal block in pediatric populations and anesthesia for robot-assisted surgery. [2] New video segments were created for the accompanying CD demonstrations of techniques such as tracheal intubation and needle ...
Midline access is a type of peripheral venous access inserted into peripheral veins and that extends further than standard peripheral catheters but does not yet reach the large central veins of the thorax. They are used when intermediate-term access (one month) is needed or when administering medications that are highly irritating to smaller veins.
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
A portable ultrasound machine used in the prehospital setting. Emergency ultrasound is used to quickly diagnose a limited set of injuries or pathologic conditions, [4] specifically those where conventional diagnostic methods would either take too long or would introduce greater risk to a person (either by transporting the person away from the most closely monitored setting, or exposing them to ...
Pulmonary ultrasound exam to evaluate for pneumothorax, pleural effusion, pulmonary edema, pneumonia, or other pathology; Identification of large-vessel-occlusion stroke and possible treatment; Fetal monitoring and evaluation in obstetric patients; Assist in procedures (peripheral intravenous access, pericardiocentesis)
The reflected ultrasound is received by the probe, transformed into an electric impulse as voltage, and sent to the engine for signal processing and conversion to an image on the screen. The depth reached by the ultrasound beam is dependent on the frequency of the probe used. The higher the frequency, the lesser the depth reached. [9]
Port access requires specialized equipment and training. Ports are typically used on patients requiring periodic venous access over an extended course of therapy, then flushed regularly until surgically removed. If venous access is required on a frequent basis over a short period, a catheter having external access is more commonly used. [1]
Access to the common femoral artery is first achieved using ultrasound guided, open, or percutaneous technique. [1] The REBOA device is then positioned either within Zone 1 (descending thoracic aorta) or Zone 3 (infrarenal abdominal aorta) before the occluding balloon is inflated with saline. [1]
