- Arterial Doppler Examination.
Arterial Doppler Examination.
An Arterial Doppler evaluates the arterial blood flow of the body. It is used many times to evaluate the arteries of the legs.It may be ordered when there is suspicion on exam or with symptoms suggestive of blockage of the arteries.
There is no radiation for this test as it uses sound waves and pressure cuffs.
This video shows how to interpret vascular arterial doppler signal wave-forms in a simple and informative fashion.
This is educational especially in teaching how to better utilise a simple hand-held Doppler.

- Laparoscopic Nissen Fundoplication (video).
Laparoscopic Nissen Fundoplication (video)
In a fundoplication, the gastric fundus (upper part) of the stomach is wrapped , around the lower end of the esophagus and stitched in place, reinforcing the closing function of the lower esophageal sphincter.
In a Nissen fundoplication,"complete fundoplication", the fundus is wrapped all the way 360 degrees around the esophagus.
This is a video of a Laparoscopic Nissen Fundoplication
performed by Peter J. Lydon, M.D.

- Compound fracture grading - Gustilo-Anderson grading.
Compound fracture grading
Gustilo-Anderson grading.
- Grade I :- clean , less than 1cm wound , minimal soft tissue injury, simple or minimally comminuted fracture. Sunday, December 12, 2010
- Renal trauma grading scale.
Basically we can divide renal trauma into five grades.
The grades I , II and III are classified as minor traumas, and the grades IV,V as major :-
- Grade I: contusion or subcapsular hematoma, without parenchymal laceration.
- Grade II: superficial cortical laceration less than 1 cm deep.
- Grade III: deep cortical laceration extending more than 1 cm.
- Grade IV:
- corticomedullary laceration with collecting system injury and urinary extravasation.
- vascular injury:- laceration or thrombosis of a segmental artery.
- Grade V:
- Multiple deep lacerations.
- Thrombosis of the main renal artery.
- Avulsion of renal hilum which devascularizes kidney.

- Bladder Injury.
Bladder Injury
Aetiology:-
- Blunt trauma : 10% of pelvic fractures.
- Penetrating trauma :gunshots or stap wounds.
- Iatrogenic:-
- Obestetric :- 0.3% with caeserean section.
- Gynaecological e.g.during a vaginal or abdominal hysterectomy.
- Urological e.g during cystescopy.
- Orthopaedic e.g. pins and screws can commonly perforate the urinary bladder, particularly during internal fixation of pelvic fractures.
- Idiopathic:- due to presence of a previous scar.
Classification(Pathophysiology):-
- Extraperitoneal rupture bladder: Usually due to fracture pelvis,and Extravasation occur at the perivesical space and may extend up to the anterior abdominal wall,If the urogenital membrane is injuried.
- Intraperitoneal rupture bladder:(The most dangerous) Usually due to direct trauma when the bladder is full,associated with electrolyte disturbance and may passed unnoticed for along time.

This is usually done during or before certain types of surgery or in the Intensive Care Unit.To see how to undergo Arterial line see the following video from New Engeland Journal of Medicine.
