What Is OSA?

OSA is a common syndrome where recurrent partial or complete upper airway obstruction occurs during sleep. These obstructions last 10 seconds or longer and are associated with significant morbidity and mortality.4 Of particular concern is that most patients with OSA are undiagnosed, reinforcing the importance of clinicians to be on the alert for signs of OSA and screen appropriately. Considering the volumes of patients that are seen today in ambulatory surgery, this presents a great opportunity

Patient Health Teaching

Health teaching to the patient and family need not be a huge burden to the perianesthesia nurse. By keeping instructions and health teaching simple and reinforcing with pamphlets and other resources for review at home, the patient is empowered with knowledge in how to manage their health and quality of life. See Appendix 1 for an example of a patient information sheet.

Screening Tools

There are user-friendly screening tools to facilitate the patient assessment and identify patients with suspected OSA. The STOP-BANG tool is a resource commonly used in the perianesthesia specialty.5 Refer to Appendix 2 for further information. Factors such as elevated body mass index, large neck circumference, and a history of loud snoring are considered red flags.2 A score of ≥3 is considered high risk for the presence of OSA.6 Once the patient is identified as potentially having OSA, the

Conclusion

With the high prevalence of OSA, ideally all patients should be screened for its presence before surgery. However, there are times when a preoperative screening visit does not occur. This may be due to a number of factors such as access to a preoperative clinic, organizational resources, and other factors. The perianesthesia nurse can be the gatekeeper in these situations and identify patients who may have undiagnosed OSA. Patients who are undergoing surgery may be a captive audience to receive
