Abstract

Impeded compliance in the respiratory system and diminished oxygenation are signs of atelectasis. Although not thoroughly explained, several mechanisms resulting in atelectasis are commonly held: compression, alveolar gas resorption, and surfactant impairment. Various and diverse factors precipitate atelectasis, such as introducing FiO2, obesity of the patient, general and intubated anesthesia, chronic obstructive pulmonary disease (COPD), the patient’s age, surgery, and type of surgery. Atelectasis results in compliance reduction, oxygenation deterioration, and exacerbation of lung impairment. Comorbidities of atelectasis include cardiomyopathy, type 2 diabetes, hypertension, and stroke.

Many patients who undergo a surgical procedure with general anesthesia experience atelectasis. Hence, it is critical to identify the underlying etiology and mechanism of atelectasis, applying a specific therapeutic approach and eliminating or reducing perioperative complications in the lungs and alveoli. Atelectasis’ prevention and treatment range from spontaneous ventilation, preoxygenation, CPAP or PEEP, and recruitment maneuvers. Properly applied recruitment maneuvers improve respiratory mechanisms and gaseous transfer in patients who manifest atelectasis under general anesthesia. Nevertheless, more studies regarding the administration and verifying the effectiveness of such procedures on oxygenation and lung parameters would further confirm, to a greater or lesser degree, their beneficial and uniform contribution to the improved prognoses of impaired patients.
