摘　　要：本组观察了２２例全麻病人诱导插管期间ＳｐＯ_２和ＰＥｔＣＯ_２的变化。按插管无通气时限的不同分为Ａ组（１ｍｉｎ）和Ｂ组（２ｍｉｎ）。通过面罩吸氧和手法人工通气，Ａ、Ｂ两组病人ＳｐＯ_２分别由９６±０．４５％和９６±０．２０％升至９８±０．２８％和９８±０．１６％，ＰＥｔＣＯ_２分别由４．５４±０．６３ｋＰａ和４．６３±０．４０ｋＰａ降至３．４１±０．６０ｋＰａ和３．５８±０．４７ｋＰａ，前后比较有明显差异，两组间无差异。插管后Ａ、Ｂ两组ＳｐＯ_２均维持在９８％以上，ＰＥｔＣＯ_２则分别升到４．７８±０．５５ｋＰａ和４．９３±０．５８ｋＰａ，与插管前比较有显著差异，虽仍在正常范围内，但已呈明显上升趋势。提示了在插管无通气状态下１～２ｍｉｎ内，缺氧不是主要的危险，而二氧化碳蓄积所带来的危害值得警惕和避免。The Changes of SpO_2 and PEtCO_2 during induction of anesthesia and intubation in 22 cases were observed 2 guoups were divided acording to the time limit of nonventilation: guoup A(1 minute)and guoup B(2 minutes). When the patients absorbed oxygen by mask and received manual artifieial)ventilation. In group A, SpO_2 increased from 96±0. 455 to 98±0. 28%and PEtCO_2 decreased from 4.45±0. 63kPa to 3. 58±0. 47kPa. In group B, SpO_2 gone up from 96 ±0. 40kPa to 3. 58 ±0. 47kPa. There was prominent significance compared pre-intubation with post-intubation, but there was no significance between group A and group B.After intubation, SpO_2 was kept above 90%in 2 guoups, PEtCO_2 increased to 4.78 ±0.55kPa in group A and to 4. 93 ± 0.58kPA in group B. It showed that hypoxemia is not main danger during intubation with non-ventilation for 1 minute or 2 minutes, but the accumulation of CO_2 should be warned and prevented.
