소아 환자에서 기관 내 삽관 후 크룹에 의한 맥반산소포화도의 감소

Abstract

Background: Postintubation croup (PC) is the rapid development of upper-airway obstruction as evidenced by hoarseness, stridor and/or chest retraction. This complication can lead to arterial desatura- tion and hypoxic bradycardia and these results may be serious, especially in pediatric patients. This study was undertaken to find the relationship between the oxygen desaturation and the duration of anesthesia. At the same time we tried to determine the incidence and etiologic factors of this complication. Methods: For this study, 400 children who received general anesthesia were studied. We investigated the several contributing factors in PC, such as age, anesthesia duration, and trauma during intubation. And the arterial oxygen saturation was measured by pulse oximetry. Results: The incidence of PC in children was 2 percent. Fifty percent of the patients with PC were 1 —4 years old. There was no significant difference between sexes. 62.6% of the children received general anesthesia over 1 hour. There was no significance detected between the degree of oxygen desaturation and the anesthesia duration. Conclusions: We confirmed that the anesthesia duration (> I hour) and age (1—4 years old) were important etiologic factors of PC. But the degree of oxygen desaturation was not correlated with the duration of anesthesia. (Korean J Anesthesiol 2001; 41: 297 — 301)
