AbstractBackground: Obstructive sleep apnea (OSA) is a sleep disorder characterized by episodes of cessation of breathing (apnea) during sleep. Unfortunately, a significant number of surgical patients are unaware they are afflicted with this disorder increasing the risks of postoperative complications. The lingering effect of general anesthesia causes an increase in frequency of airway collapse, leading to longer periods of apnea. This increasingly common sleep disorder is concerning for many anesthesia providers. Purpose: The purpose of this study was to evaluate the anesthesia provider's knowledge and postoperative management of patients with suspected or diagnosed OSA. Setting: The study setting was a local urban hospital Mountain Vista Medical Center (MVMC) in Gilbert, AZ. The study included (N=7) participants, who were predominantly male (85%) and a majority of the participants were Master’s prepared (85%) anesthesia providers. Method: An online survey was disseminated to participants via email. The survey included questions regarding the anesthesia provider's knowledge and postoperative practice habits of patients with suspected or diagnosed OSA at MVMC. Results: The response rate was (24%). All the respondents acknowledged that OSA was a risk factor for postoperative complications. Over half of the respondents (85%) reported encountering postoperative complications such as desaturation and apnea in their patients with OSA. The main complication that was encountered was postoperative apnea (50%), followed by decreased in saturations (33.33%), and one respondent (16.67%) encountered re-intubation during the postoperative period. However, the most important finding of the study is that over half of the providers did not routinely include continued positive airway pressure (CPAP)/noninvasive positive pressure ventilation (NIPPV) in their postoperative management of patients with suspected or known OSA due to the time needed to initiate the therapy. Conclusion: The study illustrates that a majority of anesthesia providers at MVMC agreed OSA is a significant risk factor for postoperative complications, but time constraints limited the implementation of noninvasive ventilation (NIV) therapies. Recommended strategies would be to establish a task force to examine this barrier to therapy and develop plans to address it.
