Abstract:
Objective To evaluate the agreement between regional cerebral oxygen saturation (rSO2) and jugular bulb venous oxygen saturation (SjvO2) during one-lung ventilation (OLV) in elderly patients.Methods Twenty-two patients of both sexes,aged 65-76 yr,with body mass index of 21-32 kg/m2,of American Society of Anesthesiologists physical status Ⅱ or Ⅲ,undergoing open pulmonary lobectomy or radical resection of esophageal cancer with combined intravenous-inhalational anesthesia,were selected.Immediately after beginning of two-lung ventilation (T0),at stable two-lung ventilation in the lateral position (T1),at 5,25 and 45 min of OLV in the lateral position (T2-4) and at the end of OLV in the lateral position (T5),blood samples were collected from the jugular bulb for blood gas analysis,and SjvO2 was recorded,rSO2 was also recorded at the time points mentioned above.Bland-Altman analysis was used to evaluate the agreement.Results SjvO2 was significantly lower at T0-5 than rSO2 (P＜0.05).rSO2 and SjvO2 were gradually decreased at T1-5 (P＜0.05).The results of Bland-Altman analysis showed that the difference between rSO2 more than 95％ and SjvO2 was within the range of 95％ limits of agreement,and the absolute value of the maximum difference was 20.8％.Conclusion There is a good agreement between rSO2 and SjvO2 during OLV in elderly patients,and SjvO2 can be recommended as an alternative to rSO2 clinically.
