Brief Summary

Postoperative pulmonary complications (PPCs) are a source of much morbidity and mortality. Rates of PPCs exceed 30% in patients with multiple risk factors. Several studies have demonstrated reduced PPCs in patients who underwent preoperative inspiratory muscle training. These studies largely focused on cardiothoracic surgery and required the use of respiratory therapists. The investigators hypothesize that preoperative, self-administered respiratory therapy would reduce PPCs in patients with risk factors for PPCs undergoing any non-cardiothoracic surgery. This study is a randomized, controlled trial comparing preoperative use of an incentive spirometry device with usual care in patients undergoing non-emergent, non-cardiothoracic surgical procedures under general anesthesia.

Outcome Measures

Primary Outcomes (1)

  • Postoperative pulmonary complications

    Composite of hypoxemia (pulse oximetry \<88% with provision of oxygen therapy beyond 24 hours after surgery); bronchospasm (new wheezing or bronchospasm with provision of bronchodilator therapy); hypercarbia (serum bicarbonate or arterial or end-tidal carbon dioxide level above reference range treated with provision of mechanical ventilation); atelectasis (radiographic evidence of atelectasis plus respiratory symptoms or abnormal lung exam findings); respiratory infection (patient received antibiotics for suspected respiratory infection and had at least 1 of following: new or changed sputum, new or changed lung opacities on chest radiograph, fever, or leukocyte count \>12,000/microliter); pleural effusion (radiographic evidence of pleural effusion and performance of thoracentesis); pneumothorax (radiographic evidence of pneumothorax); and ventilatory failure (replacement of endotracheal tube or mechanical ventilation for \>48 hours postoperatively)

    Up to 30 days after surgery

Secondary Outcomes (6)

  • Mortality

    Up to 30 days after surgery

  • Length-of-stay

  • Readmission

    Up to 30 days after surgery

  • Unanticipated hospital admissions

    Up to 30 days after surgery

  • Unanticipated hospital observation

    Up to 30 days after surgery

  • +1 more secondary outcomes

Study Arms (2)

Intervention

EXPERIMENTAL

Patient provided with instructions and video for the use of an incentive spirometry device. Patient instructed to use incentive spirometry device as frequently as every hour while awake but at least 4 times daily for at least 10 breathing cycles for 1-3 weeks before surgery. Patient instructed to record usage and any physical complaints in a diary.

Device: AirLife 4000 cc incentive spirometry device

Control

NO INTERVENTION

Patient receives only usual care as provided by perioperative healthcare providers.

Interventions

Incentive spirometry device provides improved lung expansion and respiratory muscle strength
