Post Op Care of Surgical Patient Flashcards
What is pre-operative care?
The preparation and assessment, physical and psychological of a patient before surgery
Why do we ask patients to stop smoking before an operation?
wound healing
chest infections
herpes
Why would you ask someone to reduce their alcohol intake before an operation?
Alcohol damages the liver
As a result less clotting factors and less vitamin K so clotting is impaired
What are some things important for wound healing?
Proteins/Albumin
Zinc (collagen synthesis)
Vitamin C (collagen synthesis)
Magnesium
What are some high-risk patients for surgery?
Children Elderly Immunosuppressed Obese Liver Impairment Clotting disorders Renal Impairment
What is the ASA (american society of anaesthesiologists) classification?
A scoring classification that predicts the morbidity and mortality of a patient going into surgery.
ASA 1 Healthy
ASA 2 Mild systemic disease, no functional limitation
ASA 3 Moderate systemic disease, definite functional limitation
ASA 4 Severe systemic disease that is a constant threat to life
ASA 5 Moribund patient. unlikely to survive 24 hours.
postscript E indicates emergency surgery
Give an example of an ASA 4/5 patient
Abdominal Aortic Aneurysm Rupture
Where is death almost certain with AAA?
If it’s a anterior bleed. Posterior bleed presents as renal colic and a pulsatile mass on palpation of the abdomen.
What is the grade of surgery?
Grade 1: Minor procedures e.g diagnostic endoscopy, breast biopsy
Grade 2: Inguinal hernia repair, varicose veins adenotonsillectomy, knee arthroscopy
Grade 3: Total abdominal hysterectomy, TURP, lumbar discectomy, thyroidectomy
Grade 4: Major procedures, e.g. total joint, artery reconstruction, colonic resection, radical neck dissection
According to ASA guidelines: Would you do a full blood count for all patients going into surgery?
Yes (as long as the national & local guidelines agree and it makes sense for the surgery). You would definitely do it if the patient looks anaemic.
According to ASA guidelines: Would you do a clotting screen (haemostasis)?
Not routinely for ASA 1 or 2, but consider in people with chronic liver disease in ASA 3 or 4.
In what patients would you perform a clotting screen pre-surgery?
Liver Impaired
Clotting disorders
Patients on anticoagulant
According to ASA guidelines: Would you assess kidney function for all patients going into surgery?
Yes for ASA 2, 3 or 4. Consider in people at risk of AKI for ASA 1.
According to ASA guidelines: Would you do an ECG for all patients going into surgery?
Yes for ASA 2, 3 or 4. Consider in 65+ if no ECG results available from past 12 months.
According to ASA guidelines: Would you do lung function tests for all patients going into surgery?
Not routinely for ASA 1 or 2. Consider in ASA 3 or 4 with known suspected respiratory disease.
What are the basic fasting guidelines for children and adults before surgery?
No eating for 6-8 hours before.
No fluids for up to 2 hours before.
only clear fluids allowed
i.e. coffee or juice not allowed
What are some associated medical conditions that affect surgery?
Difficult airway, obesity, cardiac disease, respiratory disease, gastrointestinal disease,
Renal failure,
Diabetes,
Haematological disorders - anaemia, sickle cell anaemia,
Allergic reactions, and those rendering patients at high risk
Additional investigations for specific illnesses – such as cardiopulmonary exercise testing to evaluate both cardiac and pulmonary function
When would you consider performing a G&S (group & save) investigation?
In higher grade surgeries and higher stage surgeries.
Surgeries where blood loss is a factor e.g. trauma, emergency surgery, ASA 5
What should you be thinking about in post-op care?
Analgesia Op Note Intake Output Mobilise LMWH? (if can't mobilise) Wounds Bowel Opening? (opiates may affect this)
How to perform fluid status assessment
Remind yourself of patient’s medical history, either past or ongoing.
Examine the patient and look at the observations, urine output, and fluid balance chart.
Assess the fluid status looking at lying and standing blood pressure, heart rate, jugular venous pressure, and mucous membranes.
Ensure you auscultate the chest and look at the peripheries for oedema.
Scan the drug chart to see if any drugs may be affecting fluid balance and whether any changes can be made. e.g. U&Es
Check the patient’s electrolytes—does any action need to be taken, or do these point to specific fluids to use?
Does the patient have any ongoing fluid and electrolyte losses that need to be taken into account?
Can fluids be taken orally instead of intravenously?
Which patients are in need of fluid optimisation
diarrhoea and vomiting
where the patient has been immobile / debilitated for a prolonged period prior to admission (which has decreased fluid intake)
elderly patients with reduced renal function that makes fluid balance maintenance more challenging
drugs that lower renal fluid exchange functions
low BMI patients in whom ‘normal’ fluid loss volumes will be more significant.
How to perform fluid optimisation
Recognise the different types of fluid used for optimisation, especially Hartmann’s, Normal 0.9% Saline and Dextrose.
Determine the correct volume and rate of administration.
Assess the volume of body fluid depletion, and how to administer fluid resuscitation to patients especially according to them being elderly / unfit / with impaired cardiac and/or renal function.
Monitor the progression of fluid optimisation
What are some of the different types of thromboprophylaxis?
mechanical drugs (heparin /LMWH + doses) antiplatelet or indirectly acting medications.
What are some of the types of patients that are indicated for thromboprophylaxis?
immobilised patients
elderly patients
etc.. add to this one
How many deaths a year occur in the UK every year after surgery?
20,000 to 25,000
80% occur in high risk patients which comprise 10% of the surgical inpatient population.
What is the timing classification of post-op complications?
Acute <24 hours
Early <1 week
Late >1 week
What often cause acute post-op complications?
2ry to GA Haemorrhage or anaemia Hypovolaemia Respiratory compromise Uncontrolled pain Emboli Damage to surrounding structures
65yr old aorto-bifemoral bypass in the morning develops acute onset abdominal pain and pyrexia, rigidity, raised lactate and metabolic acidosis
How would you manage this case?
Assessment of the patient’s airway patency (openness of the airway), vital signs , and level of consciousness. The following is a list of other assessment categories:
surgical site (intact dressings with no signs of overt bleeding)
patency (proper opening) of drainage tubes/drains
body temperature (hypothermia/hyperthermia)
patency/rate of intravenous (IV) fluids
circulation/sensation in extremities after vascular or orthopedic surgery
level of sensation after regional anesthesia
pain status
nausea/vomiting
65yr old aorto-bifemoral bypass in the morning develops acute onset abdominal pain and pyrexia, rigidity, raised lactate and metabolic acidosis
What could cause this?
Sepsis
Haemorrhage
Emboli
etc.
The first 24 hours after surgery, you must monitor vital signs. What else should you monitor?
respiratory status, pain status, the incision, and any drainage tubes should be monitored every one to two hours for at least the first eight hours.
Body temperature must be monitored, since patients are often hypothermic after surgery, and may need a warming blanket or warmed IV fluids.
Fluid intake and urine output should be monitored every 1-2hours.
If the patient does not have a urinary catheter, the bladder should be assessed for distension, and the patient monitored for inability to urinate.
If the patient had a vascular or neurological procedure performed, circulatory status or neurological status should be assessed as ordered by the surgeon, usually every one to two hours.
The patient may require medication for nausea or vomiting, as well as pain.
Patients with a patient-controlled analgesia pump may need to be reminded how to use it.
Controlling pain is crucial so that the patient may perform coughing, deep breathing exercises, and may be able to turn in bed, sit up, and, eventually, walk.
Movement is imperative for preventing blood clots, encouraging circulation to the extremities, and keeping the lungs clear; they will be much more likely to perform these tasks.
What are some early post-op complications?
Delirium DVT/PE Infection/Sepsis Poor wound healing/Dehiscence Reperfusion injuries Pressure sores Late haemorrhage
What happens if you have a post-operative ileus?
You can hear tinkling bowel sounds. Also an accent?
There is no point of feeding the patient if they have ileus.
What are some late post-op complications?
Damage to local structures - loss of function
Scarring
Chronic pain
Recurrence/Failure of surgery
What are the signs and symptoms of early sepsis?
Respiratory acidosis Decreased cardiac output Hypoglycemia Increased arteriovenous oxygen difference Cutaneous vasodilation
Your F2 colleague has asked you to chase the bloods for a colorectal patient. It is now day 6 and the ileus has resolved. He was ready for discharge today but has suddenly spiked a temp of 38. His abdomen has become peritonitic.
Bloods: WCC:23 CRP:300 Creat :200 Urea:9
How would you manage this patient?
Seems like early sepsis. Elevated WCC, CRP, Creatinine.
Full patient assessment
Decide and plan:
stable?
unstable? get investigatoins
definitive care? surgery

A 67-year-old male presents with complaints of itching, dark urine, and epigastric pain. Physical examination reveals jaundice. Initial laboratory tests show total bilirubin of 6.5 mg/dL, alkaline phosphatase elevated at 3 the upper limit of normal, and mild elevations in serum transaminases. Appropriate management includes which diagnostic test next?
a. Abdominal ultrasonography
b. Computed tomography of the abdomen
c. Magnetic resonance imaging of the abdomen
d. Endoscopic retrograde cholangiography
a. Abdominal ultrasonography
better than CT in this case as gall stones suspected, so less will be in the way in an USS than CT
