Absorption atelectasis: incidence and clinical implications.

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