American Society of Anesthesiologists

• 2006 Commissioned a Task Force that

Identified the Importance of Pre-Screening

surgery patients for the presence of

Obstructive Sleep Apnea (OSA).

• Purpose: Prevent Post-Surgical

Respiratory Events

• Anesthesiology 2006; 104:1081-93

10

2008 National Patient Safety Goals

• Proposed Goal 17 from Task Force

• Reduce Risk of Post-Operative

Complications for Patients with

Obstructive Sleep Apnea

• Organization screens potential OSA

patients prior to surgical procedures

involving centrally acting anesthetic and/or

analgesic agents.

11

Epidemiology of OSA

• It is estimated that 75% to 95% of patients

with OSA are not yet diagnosed.

• Many who are diagnosed are not being

treated effectively.

• Body Mass Index>30

• Estimates are that 26% of Adults are at

Risk

• 80%-Bariatric/60%-Diabetic/40%-CHF

12

Pathophysiology of OSA

• Awake: Airway Patent/Neuromuscular Compensation

• Sleep Onset

• Neuromuscular compensation is lost

• Airway Collapses

• Apnea Occurs

• Hypoxia & Hypercapnia ensue

• Ventilatory effort increases

• Arousal from sleep

• Pharyngeal muscle tone increases

• Patent airway restored

• Hypoxia and Hypercapnia improved by hyperventilation

13

OSA Increasing

• Obesity is increasing at epidemic

proportions which is only adding to the

problem of increasing numbers of “at risk”

patients presenting for surgery.

• Obesity Maps

14

Associated OSA Conditions

• Obesity Hypertension

• Depression Coronary Artery Disease

• Accidents Arrhythmias

• Diabetes Left side heart enlargement

• GERD LV Dysfunction

• Stroke Congestive Heart Failure(CHF)

15

Anesthesia Concerns with OSA

• OSA patients are more susceptible to airway collapse without anesthesia.

• OSA can affect all three phases of perioperative period.

• Anesthesiologists role in identification of the at risk OSA patient.

• Upper airway dilator muscles impaired.

• Effect may last for hours

• Eikermann, et. Al., AmJRespirCritCareMed 2007 175:9-15

16

Anesthesia

• Impairs airway patency

• Increases difficulty of intubation

• Brain response less effective

• Narcotics decrease sensitivity to CO2

• Respiratory drive/rate depressed

17

Anesthesia

• Upper airway muscle tone reduced with

opiates, sedatives and volatile agents.

• Perpheral control of O2 inhibited

• Recovery rooms

• Local and regional nerve block options

• Malampatti Scores 1-4

• Patients now encouraged to bring PAP

18

Anesthesia

• Unexpected Risks during

Administration of Conscious Sedation:

Previously Undiagnosed Obstructive

Sleep Apnea

• Annals of Internal Medicine, 2003;139:

707-708

• Pressman, et. Al.

(ENT) PATIENTS FOR OPIOID INDUCED RESPIRATORY DEPRESSION-

--MORE THAN OSA

• PRESENTING AUTHOR: Kim Bennion MsHS, RRT, CHC, Intermountain

Healthcare

• CO-AUTHOR: Shaylynn Uresk BSRT, RRT, SDS, Uintah Basin Medical

Center

• BACKGROUND: Opioid related deaths have been rapidly increasing1. A

recent study suggested oxygen saturation (SpO2) & other overnight

oximetry measurements may provide additional Opioid Induced Respiratory

Depression (OIRD) risk stratification insight2.

OSA – Diagnosis

• Clinical examination(history and physical

examination) carries a diagnostic sensitivity and

specificity of only 50 to 60% even when

performed by experienced sleep physicians

OSA Obvious as a Duck

31

Preoperative screening for OSA

• Stop Bang Questionnaire with H&P

• Preoperative diagnosis

• Referral to sleep disorder center

• Preoperative treatment if possible

• PAP Treatment prior to surgery

• PAP Treatment documented prior to surgery

32

Identifying the Problem

33

Stop-Bang Stop-Bang Stop-Bang

• 1. Do you Snore loudly?

• 2. Do you often feel Tired during the daytime?

• 3. Has anyone Observed you stop breathing during your sleep?

• 4. Do you have or are you being treated for high blood Pressure? Stop

• 5. BMI more than 35 kg/m ?

• 6. Age over 50?

• 7. Neck circumference greater than 40cm?

• 8. Gender male? Bang

• High Risk of OSA=Yes to 3 or more items

• Low Risk of OSA= Yes to less than 3 items

34

American Society of Anesthesiology

Recommendations

• Anesthesiologists are working with Surgeons

• Develop Protocols

• Get suspected OSA patients diagnosed and

treated prior to surgery whenever possible

• If diagnosis of OSA is made on the day of the

surgery, then patient and family needs to be

informed of the potential implications of OSA on

the perioperative course.

35

ASA Recommendations Continued

• Be prepared for difficult intubation

• Choice of anesthetic technique

• Oximetry and end-tidal CO2 monitoring

• Full reversal of neuromuscular blocking agents

• Consider non-supine extubation.

• General anesthesia preferable to deep sedation

• Spinal epidural considerations vs IV

• Use of opioids vs regional anesthesia

• Discharge delay a consideration

36

Perioperative Program Awareness

• Contact these areas all at the same time

• Bio-Ethics Department

• All medical staff members

• Grand Rounds Presentations

• Lunch and Learn AMA CEUs

• Community Outreach Programs

• Allied Healthcare Staff

• Home Care Companies

• Manufacturers

• Implement Outcome Tracking Protocols

Home Monitoring

• Check w Masimo

• DME/Hospital Revenue

• Physician/Patient Education is Key

37

38

Perioperative Management of OSA,

Budget

• Questions to Ask:

• Cost Center vs Revenue Center

• What is it going to cost to implement or

to increase awareness?

• What will it cost if we do not

implement or promote?

39

Hospital Implications

• At risk patients not served-Ethical aspects

• Patient Safety/Patient experience

• Hospital revenue

• Hospital reputation

• Hospital recognition

• Physician revenues/Sleep Lab Revenues

• Surgical Risk Liability and SurgSchedules

40

HME Considerations

• Perioperative program will:

• Drive PAP business higher

• Drive O2 business higher

• Increase your referral base

• Improved relations with area medical and

surgi-centers

41

Sleep Disorder Centers

• Additional Revenue

• Navigators???

• Increase Referral Base

• Reinforces the fact that to survive sleep

disorder centers need to diversify/change

their sales and marketing focus on more

complex patients and new opportunities.

• Periop, Stroke, CHF, Diabetes-In House

42

Working Together

• Primary Care Physicians

• Surgeons

• Anesthesiologists

• Allied Health, Nursing, Respiratory Care

• Sleep Disorder Centers

• Home Care Companies

• Hospital Administration

Post Covid Sleep Lab Thoughts

• Performing HSTs, Performing PSGs/PAP?Note: Market/Referral Sources Lost can stay lost

• Keys to Bringing Back Your Numbers

• Disposable Everything (Even HSTs)

• PPE for Technologists

• Patient Screening at every stage of process

• Room Cleaning Machines

• Negative Air Rooms

43

44

Helpful Organizations

• American Society of Anesthesiology

• ASA

• Society of Anesthesia & Sleep Medicine

• SASM

American College of Chest Physicians

ACCP

American Academy of Sleep Medicine

AASM and AARC

45

Summary

• Patients with OSA

• Make up a significant portion of the surgical population and will only

increase as obesity trends move upward.

• Most are not identified before surgery

• Have an increased risk for perioperative complications

• Can be screened diagnosed and treated to manage perioperatively

to reduce risks.

• Programs can be implemented to identify and treat these patients

without substantial increases in costs, resulting in risk reduction,

improved patient safety and better outcomes.(Needs Champion)

• Implement a Post Covid Lab Program – AASM very helpful.
