An observational study in Respiratory Complications, sponsored by Ohio State University. Completed at 1 site in United States. Open to participants aged 18 Years to 75 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2021-02-24.
Sponsored by Ohio State University · Observational
This study investigates the incidence of postoperative respiratory complications (PRCs) including: oxygen desaturation events, tracheal re-intubations within 48 hours of surgery, and failure to wean from ventilator within 48 hours of surgery - in patients with and without risk factors for OSA undergoing elective, non-cardiac surgery (NCS).
324 subjects will be enrolled into one of two groups: increased or not increased risk for OSA, n=162 patients per group. Preoperative assessments of OSA status, Mallampati score (an assessment for mouth and throat morphology), STOP-BANG test (assessment for risk of OSA), and medical history will be used to determine patient group assignment. All subjects will receive standard general anesthesia and monitoring as a part of standard of care whether or not she/he will participate in the study, including ECG, arterial pressure, SpO2, BIS, Blood pressure (BP), heart rate (HR), and respiratory rate (RR), all of which will be continuously recorded and data will be saved for every three minutes during induction using standard monitors. Standard monitoring assessments in PACU will be used, and patients with increased perioperative risk for OSA will be closely monitored for hypoxemia and other complications. The Nellcor Pulse Oximetry Sensor will be applied in PACU and continuously monitor the patient's oxygen saturation and respiratory rate for the first 48 hours postoperatively. At the end of the 48 hours, the device will be removed, and the de-identified data will be transferred to a computer with analysis software and examined for patterns in respiratory distress in both patient groups. Data collected from the Nellcor Bedside Respiratory Patient Monitoring System on pulse and oxygen saturation, as well as data on clinically significant events, such as PRCs, acute respiratory failure, tracheal reintubation, hypoxemia, CHF, MI, A-fib, and delirium will be analyzed to understand the effects of OSA on postoperative recovery

Counted across the registry records on this site, refreshed daily.
Adult patients at Ohio State University Wexner Medical Center, aged between 18-75 years, with an American Society of Anesthesiologists (ASA) physical status of I (normal healthy patient), II (patients with mild systemic disease; no functional limitation) or III (patient with severe systemic disease; definite functional impairment - with relatively stable disease, but requiring therapy) who are scheduled to undergo elective surgeries under sevoflurane general anesthesia as a standard of care.
Exclusion Criteria:
Vital signs including oxygen saturation, respiratory rate, ECG, arterial pressure, BIS, blood pressure, heart rate will be monitored and hypoxemia will be measured during anesthetic care, and oxygen saturation and respiratory rate will be measured for 48 hours after surgery with pulse oximetry. Patients in this arm will be especially evaluated for hypoxemia and other complications.
Device: Pulse Oximetry
Vital signs including oxygen saturation, respiratory rate, ECG, arterial pressure, BIS, blood pressure, heart rate will be monitored and hypoxemia will be measured during anesthetic care, and oxygen saturation and respiratory rate will be measured for 48 hours after surgery with pulse oximetry.
Device: Pulse Oximetry
Use of pulse oximetry device for 48 hours after surgery.
