Abstract:
Objective:To evaluate the effects of intraoperative fluid therapy guided by different stroke volume variation (SVV)s on bleeding during laparoscopic hepatolobectomy and postoperative renal function.Methods:A total of 135 American Society of Anesthesiologists physical status Ⅰ-Ⅲ patients of both sexes, aged 25-64 yr, scheduled for elective laparoscopic hepatolobectomy under general anesthesia, were divided into 3 groups ( n=45 each) using a random number table method: low SVV group (group L), medium SVV group (group M) and high SVV group (group H). In group L, group M and group H, SVVs were maintained at 10%-15%, 16%-20% and more than 21%, respectively.Before surgery and at 1, 3 and 5 days after the surgery, blood samples from the peripheral vein were taken for determination of serum blood urea nitrogen, creatinine and procalcitonin (PCT) concentrations.The occurrence of conversion to laparotomy, intraoperative volume of blood loss, volume of blood transfused, urine volume, operation duration, length of hospital stay and time to first flatus were recorded.On admission to the operating room (T 0), at skin incision (T 1), at the beginning of resection of the liver (T 2), after resection of the lobes of the liver (T 3) and at the end of the surgery (T 4), mean arterial pressure (MAP), heart rate (HR) and lactic acid (Lac) were recorded.The consumption of intraoperative norepinephrine, hypotension, arrhythmia and postoperative adverse reactions were recorded. Results:Compared with group L, the intraoperative volume of blood loss and consumption of intraoperative norepinephrine in group M and intraoperative volume of blood loss, the total amount of fluid infused and urine volume in group H were significantly decreased, consumption of furosemide and nitroglycerin in group H and the total amount of red blood cells infused in M and H groups were increased, length of hospital stay and time to first flatus in group M were shortened, concentration of serum PCT at 1 day after surgery was decreased in group M, MAP at T 3, 4 was increased in group M, and Lac at T 2-4 was increased in group H ( P<0.05). Compared with group M, the intraoperative volume of blood loss, consumption of intraoperative norepinephrine and consumption of furosemide and nitroglycerin were significantly increased, the total amount of fluid infused and urine volume were decreased, length of hospital stay and time to first flatus in group M were prolonged, concentration of serum PCT at 1 day after surgery was increased, MAP at T 3, 4 was decreased in group M, and Lac at T 2-4 was increased in group H ( P<0.05). There was no significant difference in the incidence of postoperative adverse reactions and intraoperative hypotension and arrhythmia among the 3 groups ( P>0.05). Conclusion:Intraoperative fluid therapy guided by SVV at 16%-20% during laparoscopic hepatolobectomy can decrease the intraoperative volume of blood loss and has less effect on renal function, which is helpful for postoperative outcomes.
