Q

How can you check for peritonitis quickly?

A
  1. Suck patient tummy in as far as possible then puff out again (esp in children)
  2. If board-like abdominal rigidity secondary to generalised peritoinism will only make minor movements
  3. Ask patient to cough
  4. Patients with inflammation of parietal peritoneum will be reluctant to cough deeply and may place their hands over area of tenderness

Q

What blood tests would you order for RIF pain?

A
  1. FBC
  2. CRP
  3. VBG
  4. U+Es
  5. Serum amylase or lipase levels
  6. Glucose
  7. Liver enzymes
19
Q

Why would WCC be elevated with RIF pain?

A

inflammatory conditions:

  1. appendicitis
  2. cholecystitis
  3. basal pnuemonia
20
Q

What are the signs of ischaemia or severe sepsis on a VBG?

A
  • Raised lactate and/or metabolic acidosis
    1. pH <7.35
    2. low/normal CO2
    3. BE
21
Q

Why do you measure U+Es in RIF pain?

A
  1. establish baseline electrolytes

2. urea used as a prognostic factor for pancreatitis (glasgow criteria)

22
Q

When is serum amylase or lipase very high?

A

pancreatitis (3x)

23
Q

When is there a slight rise in serum amylase or lipase levels?

A
  1. bowel obstruction
  2. mesenteric ischaemia
  3. posteriorly perforated duodenal ulcer
  4. mumps
  5. pancreatic carcinoma
  6. opiate medications
24
Q

Why do you measure gluocse in RIF pain?

A
  1. Check for diabetic ketoacidosis

2. part of glasgow score for pacreatitis

25
Q

When do you measure liver enzymes in RIF pain?

A
  1. Prognostic info for pancreatitis

2. Essential if clinical suspicion of biliary pathology

26
Q

What urine tests do you do for RIF pain?

A

urinanalysis

27
Q

When could you have haematuria in RIF pain?

A
  1. infection
  2. renal/ureteric calculi
  3. rarely inflamed pelvic appendix
28
Q

What would glucose and ketones in urine with RIF pain suggest?

A

diabetic ketoacidosis

29
Q

What a combo of positive leucoytes esterase and nitrates with RIF pain suggest?

A

UTI

30
Q

What would proteinuria and RIF pain suggest?

A

UTI and appendicial irritation of bladder can result in proteinuria (distinguished by performing urine microscopy looking for bacteria, which could confirm UTI)

31
Q

What imaging is used for RIF pain?

A

abdominal US

32
Q

Why do you carry out an abdominal US in RIF pain?

A
  1. biliary pathology
  2. appendicitis
  3. can also detect free fluid in abdomen
  4. female gynaecological pathology
33
Q

What other investigations would you use for RIF pain?

A
  1. Erect CXR
  2. Abdominal CT

Q

When do you perform a erect CXR in RIF pain?

A

any suspicion of perforated viscus

35
Q

What would air under diaphragm in erect CXR suggest?

A
  1. perforated peptic ulcer
  2. Meckel’s diverticulum
  3. caecal diverticulum
  4. appendix
36
Q

When would you use a abdominal CT in RIF pain?

A
  1. balance time and risk of radiation

2. useful for determining extent of intra-abdominal collections and masses

37
Q

When do you peform an ECG in RIF pain?

A

if tachycardia to confirm they have standard sinus tachycardia

38
Q

When is a ABX every useful?

A
  1. Bowel obstruction (look for dilated loops of bowel)
  2. Known IBD to rule out toxic megacolon
  3. Look for foreign body
39
Q

What are the key features of mesenteric adenitis?

A
  1. Follows upper respiratory tract infection or sore throat (cervical lympathednopathy may be present)
  2. Pain more diffuse and signs of peritonitis often absent (unlike in appendicitis)
  3. Often settles quickly
  4. Occassionaly raised temp
40
Q

What is the management of acute appendictis?

A
  1. IV fluids to manage tachycardia
  2. Analgesia
  3. 1st Line: appendectomy (open or laprascopic)
  4. Nil by mouth prior to surgery
  5. Perioperative broad-spectrum antibiotics to reduce wound infection and abcess formation
  6. DVT prophylaxis
41
Q

What is DVT prophylaxis?

A
  1. daily injection of LMW heparin

2. elastic compression stockings in calves

42
Q

What is management of septic shock?

A
  1. Call for help

2. Sepsis Six

43
Q

What is the sepsis six?

A
  1. Administer high flow oxygen
  2. Take blood cultures
  3. Give broad-spectrum antibiotics
  4. Give IV fluid challenges
  5. Measure serum lactate and haemoglobin
  6. Measure accurate hourly urine output
