Official title
Perioperative Respiratory Support and Postoperative Outcomes: Russian National Epidemiological Study "RuVent-A"
Overview
This study aims to evaluate the methodology and parameters of perioperative respiratory support (RS) and the frequency of postoperative pulmonary complications (PPCs) in the Russian Federation. The study will analyze respiratory support strategies, equipment availability, and their correlation with PPC outcomes in surgical patients.
Detailed description
Globally, around 230 million surgical procedures requiring general anesthesia and mechanical ventilation are performed annually. Postoperative pulmonary complications (PPCs) significantly impact clinical outcomes, increasing morbidity and hospitalization duration. Cohort studies have reported a 20-30% risk of PPCs in patients undergoing general anesthesia. Protective ventilation strategies, including low tidal volumes (6-8 mL/kg predicted body weight) and positive end-expiratory pressure (PEEP), have shown to reduce PPCs. However, high tidal volumes (10-15 mL/kg) remain prevalent in routine practice.
The "RuVent-A" study will collect data on respiratory support methodologies, initial ventilation parameters, types of surgical interventions, and associated PPC rates in the Russian Federation. This observational study will analyze patient and equipment data across participating centers without altering routine clinical practices.
Primary outcome measures
- Incidence of Postoperative Pulmonary Complications (PPCs) [Time frame: 30 days after surgery]
Secondary outcome measures (7)
- Level of end-expiratory pressure during anesthesia [Time frame: During surgery (intraoperative period).]
- Use of Alveolar Recruitment Maneuvers During Anesthesia [Time frame: During surgery (intraoperative period).]
- Frequency of Non-Invasive Ventilation and High-Flow Oxygen Therapy Post-Extubation [Time frame: 30 days after surgery]
- Duration of Intraoperative and Postoperative Mechanical Ventilation [Time frame: Intraoperative and up to 24 hours postoperatively.]
- Incidence of Hypoxemia Post-Surgery [Time frame: 30 days after surgery]
- Level of inspiratory oxygen fraction during anesthesia [Time frame: During surgery (intraoperative period).]
- Level of tidal volume during anesthesia [Time frame: During surgery (intraoperative period).]
