Lower Back Exam

The back is the most common source of pain in the body. Examination of the back can be a challenge due to its numerous structures, including the bones, discs, ligaments, nerves, and muscles-all of which can generate pain. Sometimes, the location of the pain can be suggestive of etiology. The essential components of the lower back exam include inspection and palpation for signs of deformity and inflammation, evaluation of the range of motion (ROM) of the back, testing the strength of the muscles innervated by the nerves exiting in the lumbar-sacral spine, neurological evaluation, and special tests (including the Stork test and Patrick's test).

Abdominal Exam III: Palpation

JoVE 10089

Abdominal palpation, if performed correctly, allows for examination of the large and relatively superficial organs; for a skilled examiner, it allows for assessment of the smaller and deeper structures as well. The amount of information that can be obtained by palpation of the abdominal area also depends on the anatomical characteristics of the patient. For example, obesity might make palpation of internal organs difficult and require that additional maneuvers be performed. Abdominal palpation provides valuable information regarding localization of the problem and its severity, as abdominal palpation identifies the areas of tenderness as well as presence of organomegaly and tumors. The specific focus of palpation is driven by the information collected during history taking and other elements of the abdominal exam. Palpation helps to integrate this information and develop the strategy for subsequent diagnostic steps.

Peripheral Intravenous Catheter Insertion

The purpose of peripheral intravenous catheter (PIV) insertion is to infuse medications, perform intravenous (IV) fluid therapy, or inject radioactive tracers for special examination procedures. Placing a PIV is an invasive procedure and requires the use of an aseptic, no-touch technique. Common IV venipuncture sites are the arms and hands in adults and the feet in children. According to the Intravenous Nurses Society (INS), the feet should be avoided in the adult population because of the risk of thrombophlebitis. Venipuncture sites should be carefully assessed for contraindications, such as pain, wounds, decreased circulation, a previous cerebral vascular accident (CVA), dialysis fistulas, or a mastectomy on the same side. The median cubital vein and the cephalic vein in the wrist area should be avoided when possible. The cephalic vein has been associated with nerve damage when used for IV placements. The most distal site available on the hand or arm is preferred so that future venipuncture sites may be used if infiltration or extravasation occurs. This video will demonstrate the insertion of a PIV, including the preparation and attachment of an IV extension s

The Guide for the Care and Use of Laboratory Animals ("The Guide") states that pain assessment and alleviation are integral components of the veterinary care of laboratory animals.1 The definition of anesthesia is the loss of feeling or sensation. It is a dynamic event involving changes in anesthetic depth with respect to an animal's metabolism, surgical stimulation, or variations in the external environment.
