ABSTRACT
General anesthesia is known to cause pulmonary atelectasis; in turn, atelectasis increases shunt, decreases compliance, and may lead to perioperative hypoxemia. One mechanism for the formation of atelectasis intraoperatively is ventilation with 100% oxygen. The goal of this review is to determine if research suggests that intraoperative ventilation with 100% oxygen leads to clinically significant pulmonary side effects. An initial literature search included electronic databases (Cumulative Index to Nursing & Allied Health Literature [CINAHL], PubMed, MEDLINE, Embase, and The Cochrane Library) using the following search terms: oxygen (administration and dosage), atelectasis, pulmonary complications, and anesthesia. Results were limited to research studies, human subjects, and English-language publications between 1965 and 2011. From this body of research, it appears that absorption atelectasis does occur in healthy anesthetized adults breathing 100% oxygen. Data reviewed suggest that absorption atelectasis does not have significant clinical implications in healthy adults. However, further research is warranted in populations at increased risk of postoperative hypoxemia, including obese or elderly patients and those with preexisting cardiopulmonary disease.
