Brief summary
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Incidence of Postoperative Pulmonary Complications (PPCs) | 30 days after surgery | The frequency of postoperative pulmonary complications (PPCs) will be measured, including conditions such as atelectasis, hypoxemia, pneumonia, acute respiratory distress syndrome (ARDS), and bronchospasm. PPCs will be evaluated based on clinical and diagnostic criteria following surgery. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Use of Alveolar Recruitment Maneuvers During Anesthesia | During surgery (intraoperative period). | The frequency of alveolar recruitment maneuvers used during general anesthesia will be assessed. |
| Frequency of Non-Invasive Ventilation and High-Flow Oxygen Therapy Post-Extubation | 30 days after surgery | The frequency of non-invasive ventilation (NIV) and high-flow oxygen therapy (HFOT) applied after extubation will be evaluated to determine their role in preventing PPCs. |
| Duration of Intraoperative and Postoperative Mechanical Ventilation | Intraoperative and up to 24 hours postoperatively. | Duration of Intraoperative and Postoperative Mechanical Ventilation |
| Level of end-expiratory pressure during anesthesia | During surgery (intraoperative period). | The level of end-expiratory pressure during anesthesia used by the anesthesiologist will be assessed |
| Level of inspiratory oxygen fraction during anesthesia | During surgery (intraoperative period). | The level of inspiratory oxygen fraction during anesthesia used by the anesthesiologist will be assessed |
| Level of tidal volume during anesthesia | During surgery (intraoperative period). | The level of tidal during anesthesia used by the anesthesiologist will be assessed |
| Incidence of Hypoxemia Post-Surgery | 30 days after surgery | The occurrence of hypoxemia (SpO2 \<92%) after surgery will be documented, along with the requirement for oxygen therapy. |
