When patient is seen at clinic, the doctor deciding their need for an operation thinks they need to be seen in the pre-op setting to ensure the patient’s readiness for theatre.
Who goes for pre-operative assessment?

Identify patient’s medical problems
Check if further information is needed to characterize patient’s medical status
Establish if patient’s condition is medically stable
Confirm appropriateness of the planned procedure
Establish plan to minimize risk to the patient

Drugs that may cause concern: Warfarin Aspirin - stop at least 10 days pre-
operatively OCP
DVT Pulmonary Embolism Discontinue 6 weeks before surgery
Steroids-dependent patients will need hydrocortisone injection to over come peri-operative stress.
Immunosuppression Diuretics
Electrolyte imbalance

Information : patient should be aware of his surgeon, staff and procedure
Teamwork: Operative team should be on the same page
Recording information: all important information should be recorded clearly in the patient notes
Communication

Aspirin• Some surgeons don’t mind
patient being on Aspirin, call registrar if unsure. If clopidogrel, MUST stop
• Will need eG+H, often bleed +++CPAP• Will need to bring in her machine
or book a bed in RCU may need recent RFTs
Radiology • need recent films. If knee
replacement, needs long leg views as well as AP, lat and skyline.
• 70 F for right total knee replacement• Hx
• On aspirin for TIAs• HTN, COPD, on CPAP
• Radiology is over 1 year old
• What do we need to think about for this patient?
Case 1
![Page 19: Preop and postop assessment](https://reader031.fdocuments.us/reader031/viewer/2022020213/58799a861a28ab95318b73ef/html5/thumbnails/19.jpg)
• Type 1 diabetic• On insulin, CANNOT stop it • Patient will be fasting, not
good for a type 1• Will need bowel prep.• Likely will need admission
the night before or morning of procedure for insulin/dextrose infusion to control BSLs
• 25 F for colonoscopy• Hx • Type 1 DM
• What do we have to think about for this patient?
Case 2
![Page 20: Preop and postop assessment](https://reader031.fdocuments.us/reader031/viewer/2022020213/58799a861a28ab95318b73ef/html5/thumbnails/20.jpg)
• Warfarin• Will need to be stopped as
bleeding is high risk
• Will need to continue theraputic clexane due to metal heart valve
• Need a clear plan on stopping and restarting warfarin.
• 80 M for excision lower leg SCC• Hx• On warfarin • Mitral valve replacement
• What do we need to think about this patient?
Case 3
![Page 21: Preop and postop assessment](https://reader031.fdocuments.us/reader031/viewer/2022020213/58799a861a28ab95318b73ef/html5/thumbnails/21.jpg)
Post operative assessment
![Page 22: Preop and postop assessment](https://reader031.fdocuments.us/reader031/viewer/2022020213/58799a861a28ab95318b73ef/html5/thumbnails/22.jpg)
• Postoperative care is the management of a patient after surgery. This includes care given during the immediate postoperative period, both in the operating room and post anesthesia care unit (PACU), as well as during the days following surgery.
• The post operative period begins from the time the patient leaves the operating room and ends with the follow up visit by the surgeon.
Post-operative care
![Page 23: Preop and postop assessment](https://reader031.fdocuments.us/reader031/viewer/2022020213/58799a861a28ab95318b73ef/html5/thumbnails/23.jpg)
Care of the surgical patient who has been transferred from the Phase I post op unit
Patient requiring less observation and less nursing care than Phase I
This phase is also known as Step down or progressive care unit
• It is the immediate recovery phase and requires intensive nursing care to detect early signs of complication
• Receive a complete patient record from the operating room which to plan post operative care
• Designated for care of surgical patient immediately after surgery and patient requiring close monitoring
Post Op PeriodPhase 1 Phase 2

• Clinical assessment and monitoring• Respiratory management• Cardiovascular management• Renal Management (urine
output)• Fluid and electrolyte balance• Control of sepsis• Nutrition

![Page 26: Preop and postop assessment](https://reader031.fdocuments.us/reader031/viewer/2022020213/58799a861a28ab95318b73ef/html5/thumbnails/26.jpg)
• Assess the patient’s:
i. Pulseii. BPiii. Temperatureiv. RRv. Oxygen saturationvi. Level of
consciousness
Immediate post-operative assessment

• Analgesia relieves suffering
• Inadequately controlled pain increases sympathetic outflow, leading to an increase HR, vasoconstriction and increased O2 demand, particularly in the myocardium and may contribute to MI
• Pain (from e.g. abdominal and thoracic procedures) may impair Respiratory function leading to atelectasis/Pneumonia
• Good analgesia allows for rehabilitation
Post Op Analgesia
![Page 29: Preop and postop assessment](https://reader031.fdocuments.us/reader031/viewer/2022020213/58799a861a28ab95318b73ef/html5/thumbnails/29.jpg)
ParacetamolShould be given regularly,
oral, rectal or IVNSAIDsUsed as adjuncts, Increase
efficacy and reduce opioid use
Can affect haemostasis and renal function gastric ulceration
OpioidsGold standard in severe pain
