A

7 days ( irreversible anti-platelet, platelet life up to 10 days)

33
Q

Max tourniquet time

A

2 hrs

34
Q

When to stop sliding scale post op

A

When person restarts eating and drinking

35
Q

Diathermy current in coagulation

A

Interrupted

Square shaped

Low voltage

36
Q

Diarthermy current in cutting mode

A

Continuous

Sinus wave form

37
Q

Diathermy frequency

A

400Hz to 10MHz

38
Q

Risk of re-infarction peri-operatively in pt 3-6 months post MI

A

16%

39
Q

Where to place diathermy pads

A

Close to op site

Away from prosthetic implant

On vascularised muscle eg thigh

40
Q

Fluid of choice post obstruction metabolic alkalosis

A

Normal saline

(chloride ions enhance excretion of bicarb)

41
Q

Difference between sterilisation and disinfection

A

Disinfection: minimise the number of microorganisms

Sterilisation: kill all microorganisms

42
Q

How many hours does take to sterilise something in glutaraldehyde

A

up to 22hrs

43
Q

Can you sterlise with 70% alcohol

A

No can only dis-infect

44
Q

How long after gastrectomy could get osteomalacia

A

1-=20 yrs

45
Q

Day 1 post op pyrexia cause

A

SIRS to trauma/pre-op infection

46
Q

Day 2-3 post op pyrexia cause

A

atelactasis

chest infection

47
Q

Day 3-7 post op pyrexia cause

A

Infection

Anastomatic leak

48
Q

Day 7-10 post op pyrexia cause

A

VTE

49
Q

ICU vs HDU admission criteria

A

ICU level 3 care: any patients with multi-organ failure or resp failure requiring advanced resp support

HDU level 2 care: Single organ support

50
Q

When to change a tracheostomy tube

A

at least 3 days post, to allow track forming

51
Q

Massive haemorrhage definition

A

Loss of >50% of in 3hr

Loss of 100% in 24hr

or >150ml/min

52
Q

Number 15 vs 10 blades

A

No 15- small curved cutting edge, for making short precise incisions, eg arteriotomy, dissecting abdo

No 10, bigger for laparotomy

No 20 even larger

53
Q

Intra-operative heat loss

A

40% radiation (electromagentic waves)

30% convection (to air immediately surrounding body)

15 % evaporation (of water)

5 % conduction

54
Q

Structures damaged in submandibular gland excision

A

Mandibular branch of facial

Hypoglossal

Lingual

Facial artery

Retromandibular vein

55
Q

Sterlisation timing in autoclave

A

3mins at 134

15mins at 121

56
Q

Confirmation of sterilisation test

A

Bowie-dick test

St andrews diagonal cross in the centre of autoclave if not fully covered by the end needs redoing

57
Q

How does the UV light sterlise equipment

A

Micro orgnaisms DNA absorbs it,

Pyrimidine dimers form, altering the form of the DNA, interfering with normal base pairing

58
Q

Sterilising endoscopic equipment

A

glutaraldehyde

59
Q

Sterilising most reusable surgical equipment

A

Autoclaving

60
Q

Diathermy modes voltage graph

A
61
Q

Branchial cyst excision nerve damage

A

Mandibular of facial nerve

Greater auricular

Accessory nerve

62
Q

Nerve damage in low anterior resection

A

nervi erigentes (pelvic splanchnic nerves that carry parasympathetic fibres)

63
Q

Sx of damage to nervi erigentes

A

impotence

64
Q

Difference between skin graft and flap

A

Flap comes with its own blood supply

65
Q

Use of statins peri-operatively

A

In pts with peripheral vascular disease, taking statins prior to vascular disease has shown a 50% reduction in perioperative cardiac events

66
Q

Control of bleeding from raw surfaces such as solid organs

A

Spray diathermy or argon plasma coaguation

AND/OR Surgicell (topical haemostatic agent)

67
Q

Fulguration diathermy

A

holding the probe away from the tissue

Spray effect with local superficial destruction

(low current and high voltage)

68
Q

Dessication diathermy

A

Electrode in direct contact with the tissue

(low current high voltage)

Results in loss of cellular water but no protein damage

Applying current over a large area

69
Q

What device is used to remove parts of the brain

A

CUSA systems minimize thermal injury and current flow to the surrounding areas.
