Abstract
Objective:To observe the effects of volume preconditioning on stroke volume variation (SVV) during laparoscopic surgery. Methods: A total of 40 American Society of Ancsthcsioiogy (ASA) classification I-II,agcd 20-60 years patients scheduled for elective laparoscopic surgery were randomized into two groups, patients without volume preconditioning (the control group) and patients with Hydroxycthyl Starch 500ml preconditioning half an hour before operation (the volume preconditioning group). The heart rate (HR), cardiac output (CO), stroke volume (SV) , SVV, systolic prcssurc(SBP) and diastolic pressure (DBP)wcrc recorded at specific time points. Results: The values of CO, SV, SBP and DBP decreased at 5 minutes after the induction and at 5 minutes after pneumopcritoncum compared with baseline value (P<Z0. 05) in the control group, while there was no significant change in those parameters at the different time points in the volume preconditioning group (P^>0. 05). The value of SVV was lower in the volume preconditioning group compared with the control group (P<0. 05). The CO was negatively related to the pressure of pneumopcritoncum in the control group, but not in the volume preconditioning group. Conclusions: Volume preconditioning can help to sustain a stable circulation during the period of induction and artificial pneumopcritocnum. There is significant relationship between SVV and volume.关键词
