摘要
为了解静脉辅助用药对通气功能的影响，作者对30例硬膜外阻滞静脉辅助用药者连续监测SpO_2及P_(ET)CO_2，发现三组患者硬股外阻滞后SpO_2、P_(ET)CO_2基本维持正常，而静脉辅助用药后，SpO_2均有不同程度的下降（P＜0．01），哌替啶、异丙嗪组达（93．24±4．13）％，安定组达（93.40±1．14）％，哌替啶、异丙嗪+安定组降至（87．50±8．67）％；手术结束时，前二组SpO_2基本能恢复正常，而哌替啶、异丙嗪+安定组患者仍处于较低水平，达（94．59±1．64）％（P＜0．01）；静脉辅助用药后，P_(ET)CO_2明显升高，哌替啶、异丙嗪组达5．79±0．69kPa，哌替啶、异丙嗪+安定组达6．88±1．48kPa（P＜0．01），且吸氧后并不能改善病人的通气状况，直至手术结束P_(ET)CO_2仍维持较高水平。因此，建议对静脉辅助用药患者除应常规吸氧外，还要密切观察其呼吸功能的变化．必要时予以面罩辅助通气，以避免高碳酸血症的发生。
After 30 patients of epidural bforking vein assisted with pethedine. Phenergan and meprobam-ate were observed, three of them were kept normal in SpO2 and PETCO2, but others in SpO2 were descended (P<0.01): (93. 24 ± 4. 13) % with Pethedine and Phenergan; (93.40±1.14) % with Pedsdine, phenergan andmeprobamate. After operation, SpO2 in the formal two were retumed norma, but still low in the latter: (94.50±1.64) % (P <0.01). Affer assisted with the drugs, PETCO2 were obviously higher. 5.79 ± 0.69kPa in the formal two and 6.88 ± 1.48 kPa in the latter of which three drugs had been used together. The Paients didn' tbreathe well even with oxygen inhalation unil the operatio ended. Thus, it is suggested tha the patients of suchcase be assisted with face mask to avoid the occme of hypereatwa.
