肺保護性通氣策略對圍麻醉期合并COPD患者呼吸力學和氧合功能的影響

肺保護性通氣策略對圍麻醉期合并COPD患者呼吸力學和氧合功能的影響摘要：目的：探究肺保護性通氣策略對圍麻醉期合并慢性阻塞性肺病（COPD）患者呼吸力學和氧合功能的影響。

方法：選取符合納入標準的圍手術期合并COPD患者60例，隨機分為兩組。對照組給予傳統(tǒng)通氣管理，實驗組給予肺保護性通氣管理。比較兩組患者呼吸力學和氧合功能的變化，觀察并記錄并發(fā)癥和不良反應的發(fā)生情況。

結果：實驗組患者PEEP和TV值均較對照組明顯降低，肺順應性較佳。實驗組吸入氧濃度較對照組更低，PaO2水平較高。兩組在并發(fā)癥和不良反應方面無明顯差異。

結論：肺保護性通氣策略在圍麻醉期合并COPD患者中具有一定的安全性和有效性。能夠降低患者的肺泡過度膨脹和肺損傷風險，改善患者的呼吸力學和氧合功能。

關鍵詞：肺保護性通氣策略；慢性阻塞性肺??；呼吸力學；氧合功能；并發(fā)癥
