General surgery document i found Flashcards
Investigation for suspected AAA?
- quick test
- gold-standard
1) Do an ultrasound FAST scan - quick and non-invasive, cannot accurately diagnose but this can be deduced from the clinical scenario (e.g. hypotensive, deteriorating)
2) Gold-standard: CT aortagram
Management of chronic anal fissure (>6 weeks)
First line is GTN
if this doesn’t work after 8 weeks, consider referral for surgery/botox
What is Gardener’s syndrome? And pattern of inheritance?
Autosomal dominant
Multiple colonic polyps
Due to colonic polyps, most patients will undergo colectomy to reduce risk of colorectal cancer
Management of cardiac tampnade
Urgent decompression of the pericardial sac
Thoracotomy (lateral incision between the ribs) or sternotomy (midline incision through the sternum)
In the emergency setting, a thoracotomy is better than a sternotomy
Pericardiocentesis (percutaneous needle decompression of the pericardium) is a viable and temporary measure of relieving cardiac tamponade when thoracotomy is not available
One of the first signs of anaesthetic poisoning?
Perioral tingling
Antidote for severe local anaesthetic toxicity?
IV lipid emulsion
known as “lipid rescue”
Daily fluid loss for an adult?
2.5-3.0 litres
Daily requirement of sodium for an adult?
~100-150mmol
3L of detrose saline or 1L of normal saline and 2L of 5% dextrose would provide the normal amount of sodium
Should you give potassium post-op?
Technically not necessary because damaged cells release potassium
Treatment of acute pancreatitis?
Fluid resucitation and oxygen
How would you manage asymptomatic AAA?
Asymptomatic abdominal aortic aneurysms are generally followed up in the outpatient setting until they reach 5.5cm, at which point elective surgery is recommended. The risk of rupture is greatest when the aneurysm is greater than 5.5cm and the benefits of undergoing elective surgery outweigh that of emergency repair of a rupture
Surgery for poorly controlled ulcerative colitis?
Pan-colectomy is the resection of the entire colon with the formation of an ileostomy, which is indicated for poorly controlled ulcerative colitis
When would you use uteroscopy for removal of renal stones?
You would use it in individuals where lithotripsy is contraindicated (e.g. pregnant women)
