1
Q

How would you examine a post op pt?

A
  • Vital signs - ABCD
  • Fluid balance – including urine output

Q

How can you examine fluid balance of a patient?

A

• Urine Output
– measure of tissue perfusion
– maintain UO >30mL/hr or >0.5mL/kg/hr
– beware in CCF and renal impairment

• What fluids are running?
– Replacement vs maintenance fluids (typically 12/24-8/24)

  • Critical for major abdominal surgery, especially GI
  • Consider total daily balance – does not count insensible losses

Q

What do you anticipate for fluid balance in post op day 2?

Q

How do you treat a superficial wound dehiscence?

A

poor nutrition, obesity, smoking, steroids, DM, uraemia, jaundice, malignancy, tissue ischaemia, infection

19
Q

  • Now vomiting ++
  • What (5) are possible causes??

Mx?

A 
Causes of vomiting:
• Post operative ileus
• Small bowel obstruction
• Ischaemic or infarcted segment bowel
• Gastric dilatation
• Drugs (narcotics)

Mx:
• Give antiemetic (maxolon, stemetil, ondansetron)
• Place NG tube: free drainage and aspirate
• Give IV fluids- check fluid balance
• Order AXR- S&E

20
Q
  • 80y woman, 2 days after open cholecystectomy is confused.

* What (5) are possible causes??

A

Causes of post operative confusion
• Hypoxia: atelectasis, chest infection, over sedation (narcotics), CCF, MI, PE
• Sepsis: chest, urine, wound, intraabdominal (bile leak)
• Medication: opiates, sedatives
• DTs (Delirium tremens; withdrawal from alcohol)
• Metabolic: uraemia, hyponatraemia, hypo or hyperglycaemia

21
Q

what can be the contributing factors to confusion in a post op elderly pt?

A
  • Stroke
  • Pain
  • Anaemia
  • Hypotension
  • Dementia
  • Sleep deprivation
  • Change of environment
22
Q

How do you manage confusion?

A
  • Get history from nursing staff or family
  • Turn on lights
  • Check history for pre-op state, alcohol, drugs, diabetes
  • Check obs
  • Look at patient. Give Oxygen
  • Ix: ABG, RBG, U&E, FBE, Blood cultures, MSU, CXR, ECG
23
Q
  • 78y man returned to the ward after abdomino-perineal resection 6 hours ago.
  • Lost 2L blood in theatre. Given 1500ml gelofusine and 2 units packed red cells.
  • BP in recovery 120/70.
  • Epidural infusion in situ- no pain.
  • IV running at 100ml/h
  • BP now 85/50

• What (3) are possible causes??

A
  • Hypovolaemia: bowel prep and fasted, long operation, behind in fluid replacement, bleeding, 3rd space loss, sepsis
  • Epidural causing peripheral vasodilatation
  • Myocardial infarct or CCF
24
Q

How do you treat hypotension in a post op pt?

A

• Decrease rate or stop epidural infusion
• Check FBE, U&E, ECG
• Give more IV fluid +/- blood.
–Start with Nsaline 1L over 30 min then review
–May need gelofusine 500ml stat if does not respond

If Gram –ve sepsis possible give IV antibiotic (3rd gen. cephalosporin or stat gentamicin)

Q

How do you manage post op fever?

A
  1. Identify site of infection

  • site of insertion
  • period of use
  • risks

31
Q

What is a central venous catheter?

  • indications
  • site of insertion
  • period of use
  • risks
A
  • good for TPN or other infusions
  • Place into IJV or subclavian vein with tip in SVC (can use femoral V.)
  • Usually insert in theatre or recovery (clean and ECG monitored)
  • Can leave in for 5-21 days (antibiotic impregnated)
  • Risk of pneumothorax, arterial puncture, haematoma (immediate)
  • Risk of thrombosis, stenosis, sepsis (later)
32
Q

What is a vascath?

  • indications
  • site of insertion
  • period of use
  • risks
A
  • temporary catheter used for haemodialysis
  • Local anaesthetic
  • Use IJV or femoral vein (NOT subclavian)
  • Leave in maximum 5 days
  • Ultrasound control to insert is optimal
33
Q

What is a permcath?

  • indications
  • site of insertion
  • period of use
  • risks
A
  • long term catheter for haemodialysis
  • with dual lumen
  • general anaesthetic
  • Place in IJV or EJV
  • Tunnelled cuffed catheter to prevent infection and displacement
