Peri-op management Flashcards

1
Q

Peri-op considerations for T1DM pt

A

Put patient on list first Omit AM insulin if surgery is in morning Start SLIDING SCALE (5% dextrose w 20mM KCl at 125ml/hr + 50U actrapid) - continue sliding scale until tolerating food - check glucose hourly

Q

Peri-op consideration for T2DM pt (no insulin tx)

A

Omit any oral hypoglycaemic on AM of surgery - if eating post-op: resume oral hypoglycaemic with meal - if not eating: check fasting glucose + start sliding scale

Q

Peri-op Considerations for pts on warfarin

A

Low VTE risk: stop warfarin 5 days pre-op + restart the next day High VTE risk: - 5 days preop - stop warfarin + start LMWH - 1 day preop - stop LMWH - Post op: start LMWH + warfarin (stop LMWH when INR>2)

25
Q

3 specific risks of surgery in patients with jaundcie

A

Specific risk of surgery in patients w COPD

A

1) atelectasis 2) aspiration 3) pneumonia

28
Q

Complications of anaesthesia

A

Propofol induction –> cardiorespiratory depression Intubation –> oropharyngeal trauma, sore throat, oesophageal intubation Loss of pain –> urinary retention, pressure sores, nerve palsies Loss of muscle power –> corneal abrasion, atelectasis + pneumonia Anaphylaxis - rare but serious!!

29
Q

Indication for spinal/epidural anaesthesia

Aggressive pain + nausea Mx Early mobilisation Remove drains + catheters ASAP

31
Q

General surgical complications

32
Q

Post-op haemorrhage classification

A

Primary: starts during surgery Reactive: due to increased CO + BP Secondary: >24h after surgery, often from infection

33
Q

Causes of post-op urinary retention

A

Drugs: opioids, anaesthesia, antimuscarinics PAIN –> sympathetic activity Social: hospital environment

34
Q

Q

Wound infection: Timing? RFs?

A

5-7 days post-op RFs: pre-op: DM, steroids, viscus perforation operative: contaminated/dirty, duration, pre-op abx post-op: contamination from staff

37
Q

Wound dehiscence: Definition? Timing + presentation? RFs? Mx?

A
  • Rupture of a wound along the suture line - 10 days post-op, preceded by serosanguinous discharge - RFs (same as incisional hernia?): Pre op: DM, obesity, smoking, malnutrition, roids During operation: surgical skill, site of incision Post-op: High IAP, infection Mx: ABC - Place gauze soaked in warm saline over the wound - Fast bleep surgical reg + warn theatre + anaesthetist - Opioid analgesia - Prep pt for surgery: G+S, X-match, clotting, stop warfarin
