Abstract:
Objective To evaluate the effects on Stroke Volume Variation (SVV) during ventilation with selective lobar collapse (SLC) and one-lung ventilation (OLV) in thoracoscopic operation. Methods 60 patients scheduled for thoracoscopic operation to treat lower thoracic esophageal cancer or cardial carcinoma were randomly assigned into two groups: patients in one lung ventilation (OLV) group received right lung ventilation and left lung collapses, patients in selective lobar collapse (SLC) group received right lung and superior lobe of left lung ventilation by the use of endobronchial blocker. The intraoperative blood oxygen saturation (SpO2) and end-tidal carbon dioxide tension (PETCO2) were maintained in normal range. Record SVV, cardiac output (CO), stroke volume (SV), systolic blood pressure (SBP), diastolic blood pressure (DBP), the heart rate (HR), cardiac index (CI) at four time points: 10 min after two lung ventilation in supine position (T1), 10 min after two lung ventilation in lateral position (T2), OLV or SLC for 10 min after the pleura was opened (T3), two lung ventilation for 10 min before the pleura was closed (T4). Results There was no statistically significant difference between the two groups (P > 0.05). Comparison between groups: There was no significant difference between the patients in OLV group and SLC group, including HR, SBP, DBP, CO, CI, SV and SVV (P > 0.05). Comparison in the group: SBP and DBP in OLV group and SLC group were significantly higher than T1at T3(P < 0.05). The SVV of OLV group and SLC group was significantly reduced at T3and T4(P < 0.05). Conclusion There was no significant difference in SVV monitoring of Vigileo monitoring with OLV and SLC in thoracoscopic operation. SVV can be used to monitor blood volume state during ventilation by SLC.
