Q

What causes AAA?

A

Age (5% of the population >60y), also around 5x more common in men. Men are now screened for it as standard.
Also be aware of other causes such as SYPHILLIS, EHLERS-DANLOS and MARFAN’S SYNDROME (connective tissue disorders)

Q

Investigations for AAA?

A
  • Ultrasound is diagnostic for AAA - but if it has already ruptured should not waste time doing this
  • ECG
  • BLOODS: amylase and get a group and save and a cross match for 10U or more.
    If the patient is stable and you are uncertain if this is the correct diagnosis consider CT but should not delay treatment for this

Q

How should you manage AAA?

A
  • If you suspect ruptured AAA immediately inform theatres and an experienced anaesthetist and then perform the above investigations
  • Gain IV access with two wide-bore cannulas and then give the patient some O- blood - DO NOT TRY to boost their blood pressure too much as this might rupture a contained leak: aim for systolic <100
  • Get patient to theatre as quickly as possible
    Consider prophylactic abx: CEFUROXIME AND METRONIDAZOLE

30
Q

How might a miscarriage present?

A

Acute vaginal bleeding with or without pain. Sometimes bleeding can be profuse and cause collapse or faintness
- Abdominal pain and cramping

31
Q

What causes might there be for a miscarriage?

A
  • Might be spontaneous or might be repeated (infertility)
  • Chromosomal abnormalities of fetus

35
Q

What are some important causes of ovarian cyst?

A

Cysts are either:
- FUNCTIONAL - very common and form as part of the menstrual cycle. Usually these are harmless, short-lived and asymptomatic
- PATHOLOGICAL - much less common. They are an abnormal growth and while the majority are benign some can be cancerous.
Can be associated with endometriosis
PCOS

36
Q

What investigations should be done in people with suspected ovarian cyst?

A
  • USS
  • Bloods looking for cancer markers (high levels doesn’t necessarily mean cancer because can be high in a range of things). Ca-125 in ovarian and B-hCG in molar pregnancy
37
Q

How should we initially manage ovarian cyst in the ED?

A
  • In most cases they will disappear by themselves with no need for treatment
  • If the woman is post-menopausal then she might have a slightly higher risk of cancer and so might suggest monitoring over a year
  • IV FLUIDS - consider bloods if you suspect blood loss
    Consider referring to surgeons - might need surgical repair
38
Q

What are some clinical features of acute pancreatitis?

A

First symptoms are usually severe epigastric pain with nausea and vomiting - this can also be the clinical picture with lots of things but acute pancreatitis should always be a differential.
- As the conditions progresses there might be involvement of the peritoneum and the retroperitoneum leading to pain bearing through to the BACK
- If severe: tachycardia, hypotension and oliguria
O/E: will be mostly unremarkable apart from some epigastric tenderness. In severe disease might find some GREY-TURNER’S bruising or some CULLEN’S BRUISING

39
Q

What are some causes of acute pancreatitis?

A 
GET SMASHED 
G - Gall stones (38%)
E - Ethanol (35%)
T - Trauma 
S - Steroids 
M - Mumps 
A - Autoimmune 
S - Scorpion venom 
H - Hyperlipidaemia, hypercalcaemia, hypothermia 
E - ERCP and emboli 
D - Drugs
40
Q

What investigations should we do in someone in whom we’re suspecting acute pancreatitis?

A
  • BLOODS: get FBC, U&E LFT and ask for an AMYLASE. Expect it to be raised (>1000) although degree of elevation does not necessarily reflect severity of disease
    ○ LIPASE is more sensitive and specific
  • ABG
  • AXR: showing NO PSOAS SHADOW (due to high retroperitoneal fluid)
  • CXR might help you exclude other causes such as bowel perforation
  • CT
  • USS
    CRP>150
41
Q

How should we initially manage someone with acute pancreatitis in the ED?

A
  • NBM likely need an NG tube
  • Admit
  • Analgesia (pethidine or morphine -something strong)
  • Keep an eye on obs
    ERCP and gall stones removal - call general surgery
42
Q

What are some clinical features of someone presenting with peptic ulcer disease ?

A
  • Sharp epigastric pain.
    ○ Might be associated with oesophagitis like pain - sharp central chest pain that is worse with lying and might be accompanies by heart burn, metallic taste in mouth
    ○ Patients quite often point with a single finger to the point where the pain is - this might help us narrow down the cause to stomach pain rather than more sinister chest pain
    ○ Might have some relationship with food but this is less clear (duodenal ulcers are the most common and these are made worse by food, gastric ulcers eased by food)
  • Epigastric pain
  • Anorexia and weight loss if it’s been going on a while
  • Some nausea and some vomiting although not a lot - vomiting might relieve the pain
43
Q

What are some important causes of peptic ulcer disease?

A
  • DRUGS: NSAIDs, steroids SSRIs
  • H.Pylori
  • Blood group O
  • Smoking
  • Alcohol

  • FBC U&E
  • Could test for H.pylori - stool sample of antigen
  • Endoscopy for high risk group (>55)
45
Q

How should we manage peptic ulcer disease initially in ED?

A
  • Get them onto an endoscopy clinic especially if they are over the age of 55 or with other red flag symptoms.
  • Give them PPI
  • Triple therapy for H.pylori (PPI, Amoxicillin, Clarithromycin)
46

50
Q

What are some clinical features of renal colic?

A
  • This is when there is intermittent in the flank or the loins or even the groin. Severe and coming and going in waves
    ○ The pain is in this pattern due to ureteric peristalsis
  • The patient might be having urinary symptoms as well such as :
    ○ Anuria or dysuria
    ○ OR increased frequency, urgency, suprapubic tenderness
    ○ Change in smell to urine

Q

How should we consider managing a patient with renal colic in ED?

A
  • Pain killers (might need IV)

- Fluids - important to keep pt hydrated

54
Q

What are some clinical features of urinary tract infections?

A

In terms of abdominal pain in UTI the pain is most likely to be suprapubic, although be aware of possible loin and flank pain as well and consider an upper urinary tract infection (pyelonephritis).
- URINARY SIGNS:
○ Urgency
○ Frequency
○ Feeling of incomplete emptying
○ Haematuria
○ Dysuria
○ Smelly urine
- Fever, rigors and tenderness are also suggestive of an upper UTI

A
  • Urine dip
  • Pregnancy test
  • Bloods: FBC, U&E, cultures maybe if pyelonephritis
57
Q

How can we manage a UTI in the ED?

A
  • Antibiotics (follow guidelines, trimethoprim, nitrofurantoin, pivmecillinam)
