Postoperative Ventilation

Benefits of postoperative ventilation are as follows:

1. Airway protection and prevention of aspiration
2. Improved ventilation and good oxygenation
3. Decreased work of breathing

4- Avoidance of hypercarbia and hemodynamic instability in sedated patients
5 -Direct endotracheal access for removal of secretions.

Postoperative ventilation is done in following circumstances

1. Patients not able to mantain a patent airway because of residual anesthetic effect, cerebral ischemia/injury, hyponatremia, congestion after reconstructive surgery, vocal cord paralysis or anaphylaxis.
2. Patients with limited muscle excursion due to upper abdominal/ thoracic surgery, residual neuromuscular relaxation, hypoglycemia, hyponatremia and acidoses.
3. Patients with respiratory compromise due to excessive atelectasis, acute respiratory distress syndrome, or chronic obstructive pulmonary disease.
4. Intraoperative uncontrolled hypertension, myocardial ischemia/infarction, or arrhythmias, hypoadrenalism are also indicators for continued postoperative ventilation till the condition stabilizes prior to extubation.
