Q

What is the difference between the clean area vs. mixed area vs. contaminated dirty area?

A

The goal of keeping areas as clean as possible is to minimize risk of infection.

Clean area = restricted to clean traffic = sterile supply, operating room, scrub sink; brand new pair of clean surgical scrubs on

Contaminated/dirty area = contaminated traffic –> anesthesia prep, lounges, offices

Mixed area : the more in between areas. Not sterile enough for surgery but still fairly clean.

Q

What is an operating room? What is positive pressure/ what is the benefit? What should you have in there in terms of lighting. What about surfaces?

A

Single Door
Keep door closed once the team is in the room

Scrub Sinks Outside the OR

Positive Pressure Air Flow = pressure higher in room than surrounding area so air can leave the room and not come back in (TPLO, total hip; to be as clean as possible b/c highest risk for post op implications)

Emergency Lighting

Minimize Horizontal Surface

Clean! Clean! Clean!

Surgical suite includes more than one operating room + recovery area, etc.

Q

What are nonsocomial infections? What do we do to mitigate them?

A

Nonsocomial infections are infections that are aquirerd within the hospital. The purpose of all of these areas, scrub sink , changing scrubs, antiseptics ect, is to prevent a nonsocomial infection.

Q

What are the types of warming for patients? What is active warming? active core warming? Passive warming? What should you remember about the speed at which you warm a patient?

A

Minimizes heat loss during surgery

Passive Warming vs. Active Warming
Passive Warming
- Blanket or towels [act as an insulator]
Active Warming
- Heat source applied directly on the patient
Active Core Warming
- Heat applied centrally = giving warm IV fluids

Rewarm quickly, but carefully

Q

What are the types of Monitoring equipment?

A

Monitor vital signs
Temperature
Rectal thermometer vs. Esophageal temperature probe

Heart Rate/Rhythm
ECG vs. Stethoscope vs.
Esophageal tube

Respiratory Rate
Capnography

Blood Pressure
Doppler vs. Oscillometeric
Monitoring Device

Oxygen Saturation
Pulse Oximeter

26
Q

What are the parts of an anesthesia machine?

A

Delivers oxygen

Delivers anesthetic gas

Assists with ventilation

Removes exhaled carbon dioxide

27
Q

What are important notes about temperature monitoring in anesthesized patients?

A

Monitoring prevents hypothermia and hyperthermia

Monitored every 5 – 10 minutes until:
Patient is in sternal recumbency
Body temperature between 99F to 102F

Rectal Thermometer vs. Esophageal Temperature Probe

Over heating

28
Q

What is an ECG?

A

Continuously monitors electrical activity of the heart
Information about heartrate and rhythm

Electrical signal is picked up by electrodes, amplified and displayed on a screen

29
Q

What is an Esophageal stethoscope?

A

Thin flexible tube attached to regular stethoscope

Allows lungs and heart auscultation of draped patient

Intubated patient

30
Q

What are the 3 values of Arterial blood pressure ?

A

Systolic pressure
Diastolic pressure
Mean arterial pressure (MAP)

31
Q

What is direct blood pressure monitoring? What is indirect blood pressure monitoring? What is the gold standard of blood pressure monitoring?

A

Direct: Arterial Blood pressure -> gold standard

  • monitor heart rate and rhythm along with blood pressure

Indirect:

Doppler ultrasound and Oscillometeric. Doppler only gives you systolic blood pressure. Oscillometeric gives you systolic, diastolic, and map.

32
Q

How do you take a doppler blood pressure reading?

A

Ultrasonic Doppler Method

Occlude arterial blood flow by inflating a cuff

Deflate the cuff until the blood flow goes back to normal

When pressure in the cuff is just below systolic blood pressure, the blood flow can pass the cuff and is detected by the doppler probe

Probe use ultrasonic waves to detect pulsatile blood flow or vessel wall motion and converts this to an audible signal = HEART RATE

33
Q

How do you measure a blood pressure cuff?

A

Width of cuff is about 40% circumference of limb.

34
Q

What does Oscillometeric Blood Pressure Monitoring Device measure?

A

Systolic arterial pressure
Diastolic arterial pressure
Mean arterial pressure [MAP] -> most accurate on these machines
Pulse rate

35
Q

What are some reasons oscillometeric blood pressure is used over other forms of blood pressure reading? What is the downside?

A

Non-invasive detection of arterial blood flow
Commonly used

Less accurate than Doppler or invasive blood pressure monitoring

Various components lead to inaccuracies

36
Q

How can you monitor patient respiration?

A

Movement of thorax

Movement of rebreathing bag

Auscultation [esophageal vs. stethoscope]

Condensation of ET tube

Monitors
Capnograph

37
Q

What is a capnograph? What does it measure?

A

Measure exhaled carbon dioxide in patient’s breath over time

Can diagnose respiratory airway obstruction or leak in the ET tube cuff

ETCO2

Measure respiratory rate

38
Q

What is a pulse ox? What does it measure? Where can it be attached? What is the drawback?

A

Non-invasive method of measuring the oxygen saturation of hemoglobin (SpO2) in arterial blood
Provides pulse rate of patient

Attached to the patient’s tongue, lip, ear (if not pigmented), paws, toes, and thin skin folds on extremities

Can be easily affected

39
Q

What other things can affect pulse ox?

A

Pigmentation, poor bloodflow, motion, light or if the tongue dries out. If it does dry out you can add water to the tongue or use a tongue soaked gauze on the tongue.

40
Q

What should you always remember when monitoring anesthesia?

A

NEVER TRUST THE VITAL SIGN MONTIOR’S VALUE ALONE

Always double check these values using traditional monitoring techniques

Example:
Check the monitor’s heart rate values versus what you actually hear using your stethoscope

41
Q

What is the importance of fluids during surgery?

A

Intraoperative fluid therapy helps restore and maintain tissue fluid, as well as electrolyte homeostasis and central euvolemia

42
Q

What are the fluid rates used for patients in surgery?

A 
10 – 15 mL/kg/hour of crystalloid fluids
Lower rate (5 mL/kg/hour) may be used for healthy patients undergoing less invasive elective procedures
43
Q

What are typical causes of fluid loss in surgery?

A

Fluid losses
Large abdominal and thoracic incisions have much larger evaporative losses

44
Q

What is a good idea in terms of fluid preparation for surgical patients?

A

Prewarm fluids

45
Q

Where should a patient undergo surgical prep? What is involved in surgical prep?

A

Should take place in the preparation room
Anesthesia/surgical prep area

Surgery site is clipped with adequate margins for the procedure to be performed

Usually performed under anesthesia

Initial scrub

Patient moved to the OR and then 3 additional scrubs performed

46
Q

What is the goal of skin preparation?

A

Reduce resident skin flora to prevent infection

Achieve residual antiseptic activity
It is NOT possible to completely sterilize the skin
