CT! If find fracture, do imaging of whole spine

101
Q

Why might patient with orbital fracture get bradycardia

A

Due to trapped interior rectus muscle… causing a oculocardiac reflex. Should do Sx release

If have urethral injury, and it’s so bad we need to do Sx at a later date, how to deal with urine

A

Urine diverted to suprapubic catheter

116
Q

Our two urethral injuries: anterior and posterior. Location? Association? Tx?

A

Anterior:
Distil to membranous urethra. Straddle, penile fracture etc. do catheter, supeapubic if needed. May need Sx

Posterior:
Membranous and prostatic. Seen with hip dislocation. Usually do normal catheter, but may need same as above

117
Q

Differences between extra and intra peritoneal bladder injury

A

CT. And do CT guided hematoma evacuation. Lugs tree the vessels needed. Transfuse as needed

120
Q

Why do rectus sheath hematoma more commonly occur below arcuate

There is no posterior sheath below arcuate. So there is huge shearing forces of the rectus abdominus. Causing a rupture

Q

General workup for pelvic fractures

A

Assess hemodynamic (around 40 % have bleed and need transfusion). Apply pressure to ASIS both sides to

Unstable patients should have binder over trachanters (this tamponades any bleed). Then do angio embol.

Non-tunnelled you do exactly what little micro George said. Isolation of organism from central line and peripheral blood sample, with a greater concentration at the central line. I.e. a shorter time to culture in the Central line in the peripheral vein.

Tunnel catheter you do a similar saying but you can take the bus Alexi date from the subcutaneous track Lane
