摘要
肺手术时,为防止血液,脓液,分泌物等流入下肺,并为术者提供安静的手术操作条件,通常需插入双腔支气管导管(Carlen或White导管),选择性地进行健侧肺(下肺)的通气与麻醉。然而,单肺通气时由于患肺不张和肺内分流增加,可发生显著的低氧血症。为防治单肺通气时的低氧血症,有人采用患侧肺持续吹氧,也有人对患侧使用高频通气,均取得了一定效果。本文试用一种新的通气方式—频率循环喷射通气(FCJV)与普通高频喷射通气(FHJV)进行对照,探讨它对动脉血气的影响。
A new mode of jet ventilation, freque-ncy change jet ventilation (FCJV)., was used in operated lung together wth inter-mittent positive pressure ventilation (IPPV) in normal lung during lung operation in 16 patients. Its effect on arterial blood-gas tensions was compar ed with that during bilateral IPPV and conventional high frequency jet ventilation (HFJV) in operated lung accompanying with IPPV in normal lung. It was demonstrated that remarkable hypoxia might occur in some patients during one-lung ventilation of IPPV, and the added use of FCJV or HFJV in the operated lung could signifi cantly improve arterial oxvgenation. FCJV was shown to be more beneficial than HFJV for ventilation and oxygenation.Therefore, the new mode of jet ventilation, FCJV is expected to become one of the methods in prevention and treatment of hy poxia during one-lunn ventilation.
