Q

How haemodialysis different from haemofiltration

A

Dialysis: counter flow of blood and dialysate fluid separated by semi-permeable membrane

Filtration: High hydrostatic pressure pushing blood into semi-permeable membrane, forming ultrafiltrate (small molecules and electrolytes pass through the membrane). Ultrafiltrate is then disposed and replaced by normal fluid

In pt with clear signs/sx, 1. any circumferential dressing should be removed and pt reviewed after 30 mins 2. If persists, needs urgent decompression In pt with Dx uncertainty 1. record intracompartmental pressures 2. If diastolic blood pressure - the compartment pressure < 30 mmHg ; suggests positive 3. Needs to D/w consultant if positive whether needs decompression 4. If absolute compartment pressure >40mmHg, it is definitely compartment syndrome

BOA guidelines: Spinal clearance principles in trauma
1. Inclusion: unconscious, unable to cooperate or who have distracting injuries 2. Examine the entire spine on arrival: any injury found requires urgent imaging 3. If unlikely to be conscious in 48hr, need radiological imaging 4. Radiological imaging: CT Head (extend to c spine), CT CAP for coronal view, AP and lateral xray of thoracic and lumbar. needs reporting by a radiologist before clearing the spinal immobilisation measures. MRI needed for cord injury
109
BOA Guidelines for open fractures

110
BOA guideline: Timing to debride an open fracture
Debridement should be performed using fasciotomy lines for wound extension where possible — Immediately for highly contaminated wounds (agricultural, aquatic, sewage) or when there is an associated vascular compromise (compartment syndrome or arterial disruption producing ischaemia). — within 12 hours of injury for other solitary high energy open fracture — within 24 hours of injury for all other low energy open fractures.
