Official title
Evaluation of OSA Risk Levels in the Preoperative Period of Adult Patients With Planned Dental Procedures Under Anesthesia and Correlation With Postoperative Complications; A Multicenter Study
Overview
Obstructive sleep apnea (OSA) is a sleep-related respiratory dysfunction. The prevalence of OSA is increasing with the increasing rates of obesity and elderly population worldwide. Perioperative anesthesia management should be adjusted to improve patient safety in patients with OSA. In OSA patients, positive pressure ventilation support may be required in the preoperative period, various ventilation strategies may be required in the intraoperative period, different pharmacologic agents may need to be avoided, and intensive care unit follow-up or noninvasive ventilation support may be required in the postoperative period. However, it is reported that a significant percentage of OSA patients remain undiagnosed. ASA (American Society of Anesthesiologists) has reported the criteria that should be questioned in order to determine the risk of patients in terms of OSA and to initiate the diagnostic process in risky patients and to make appropriate anesthesiologic arrangements in the perioperative period. In addition, the STOP-BANG assessment scale, which is widely used all over the world in OSA risk assessment, is also used in OSA risk assessment. It is thought that dental caries and extraction needs may be higher in OSA patients, especially since open-mouth sleeping accompanies the situation. In this respect, it is also important for patients to be diagnosed with OSA as it may prevent dental damage due to open-mouth sleeping in the future. Identifying patients at risk for OSA and directing them to the diagnostic process is very important for patient safety. Within the scope of the study, the criteria recommended by ASA and STOP-BANG score will be evaluated and recorded. Risk stratification in terms of STOP-BANG questionnaire and ASA criteria will be done separately for each patient and for each classification method. Patients at high risk will be consulted to the relevant medical department in the preoperative period for further investigation and treatment. In addition, it is aimed to correlate the risk levels determined in the study with postoperative respiratory complications and recovery time.
Interventions
- Other The STOP-BANG questionnaire for determining OSA risk level.
An assessment questionnaire including OSA-related physical characteristics and symptoms and signs to be questioned individually in each patient will be examined by the physician. - Other ASA recommended criteria for determining OSA risk level.
An assessment questionnaire including OSA-related physical characteristics and symptoms and signs to be questioned individually in each patient will be examined by the physician. - Other Record of postoperative complications
Respiratory complications as laryngospasm/bronchospasm, apnea, hypoxia, duration and amount of need for additional oxygen support and recovery time (duration of modified aldrete score of 9 and above) will be recorded.
Primary outcome measures
- Determination of OSA risk levels of patients [Time frame: Preoperative period]
- Postoperative respiratory complications [Time frame: For 4 hours after the end of surgery]
- Follow-up of indicators of airway obstruction [Time frame: For 4 hours after the end of surgery]
- Duration of recovery [Time frame: For 30 minutes after the end of surgery]
Secondary outcome measures (1)
- Comparison of the effectiveness of STOP-BANG questionnaire and ASA criteria in determining OSA risk level [Time frame: Perioperative period]
