Great Mix Flashcards
Hickman Line
This is a an example of a long term central venous line which is inserted in a similar way to a central line (usually subclavian).
The remnant of the line is tunnelled subcutaneously, which decreases the incidence of line infection.
These are indicated for long-term parenteral nutrition, long-term intravenous antibiotic therapy and chemotherapy.
What is Mannitol?
Mannitol is an osmotic diuretic which can be used to lower raised intracranial pressure or drive the urine output in a patient with obstructive jaundice to prevent hepato renal syndrome.
IM Femoral Nail
This is an intramedullary femoral nail which is used to internally fix femoral shaft fractures.
Interlocking screws are used to fix the nail. They are usually removed after 12 / 18 months.
Monopolar Diathermy Handle
Monopolar diathermy is used for coagulation and dissection of tissue during open or laparoscopic surgery.
Swan Ganz catheter
This is a Swan Ganz catheter which is used to measure the pressures in the heart, the pulmonary artery wedge pressure and can also be used to measure the cardiac output.
These are used in the intensive care setting and are typically inserted into a central vein.
Ryles NG Tool
This is a Ryles nasogastric tube which is primarily used for decompression (drip and suck) in bowel obstruction, but can also be used to insert drugs or contrast into the GI tract.
After explaining what you are about to do to the patient, you will require a NG tube which has been in the fridge as it is stiffer, some lubricant, a bladder syringe, a drainage bag and pH dipstick.
The correct position of the tube is checked by aspirating gastric contents and checking for acidity on pH dipstick, if this is unavailable then air can be inserted to the tube and the epigastrium auscultated for bubbling. Finally, an x-ray can be taken to identify the tube.
Once the tube is in the correct position a bag is attached and it is taped to the patients face.
Surgical vs anatomical neck of the humerus?
The surgical neck is much more frequently fractured than the anatomical neck of the humerus. This type of fracture takes place when the humerus is forced in one direction while the joint capsule and the rotator cuff muscles remain intact.
It is a clinically important anatomical feature of the humerus as it is the most frequently fractured site of the proximal humerus, putting the axillary nerve and posterior circumflex humeral branch of the axillary artery at risk.
General principles of fracture management?
Reduce (open or closed)
Hold (metal or no-metal)
Rehabilitate (move, physiotherapy, use)
What hold options are there for fractures?
Closed = plaster, traction
Fixation
Internal fixation?
Intramedullary - nails, pins
Extramudllary - plates, pins
External fixation?
Monoplanar, multiplanar
Causes of patellar effusion:
Damaged structure in the knee.
Synovoitis, OA, torn menisucus, torn ACL, chondral injury
Movements to test median nerve?
thumbs up don’t let me push it down
Movements to test radial nerve?
o Fingers straight don’t let me push them down
Movements to test ulnar nerve?
spread fingers – don’t let push it in
o Looks like a U when they spread
Heberden’s nodes?
Bony bumps on the DIPs are called Heberden’s nodes.
More OA?
Bouchard’s nodes?
Bony bumps on the PIPs
Mora RA?
Empty can test assesses what?
Supra-spinatus weakness
Scarf test assess what?
Rotator cuff pathology
Joints involved in RA?
Multiple joints affected: usually small joints of hands and feet such as the proximal interphalangeal (PIP) joint, metacarpophalangeal (MCP) joint, wrist, knee, ankle, metatarsophalangeal (MTP) joint, and cervical spine
Hawkin’s kenedy test - robot arm push down assess what?
Subacromial impingement
The most common etiology of a winged scapula?
damage or impaired innervation to the serratus anterior muscle.
External rotation against resistance
This clinical test assesses the function of the infraspinatus muscle and teres minor.
Arthroscopy
Can be used to visualise the meniscus within the joint and is the gold-standard investigation for diagnosing a meniscal tear. Arthroscopy can also be used to repair or remove damaged sections of the meniscus.
