Abstract:
Objective To observe the effects of different levels of stroke volume variation (SVV)directed fluid therapy on prognosis in elderly patients.Methods One hundred and ten patients (male 67 cases,female 43 cases,aged 65-80 years,ASA grade Ⅰ or Ⅱ)undergoing abdominal sur-geries were randomized into three groups on the basis of SVV level:1 1%≤SVV≤14% (group H,n=37),7%≤SVV≤10% (group M,n = 37),3% ≤ SVV≤ 6% (group L,n = 36).Each group ac-cepted different fluid therapy strategy.Perioperative intake and outtake volume were recorded.Progno-sis indicators included gastrointestinal function recovery,post and total length of hospital stay and so on were collected.Postoperative complications were also recorded.Results Along with the level of SVV dropped,The volume of colloid and crystalloid among groups were significantly increased (P <0.05).There were no remarkable difference in the time interval of activity off bed,liquid diet,gastrointestinal decompres-sion and catheterization.Group L had a delayed exhaust time compared with group H (P <0.05).Patients in the group M had a shorter time to have semi-liquid diet.The transition of diet was also shortest in the group M.But these differences were not statistically significant.The group M also had a shorter time in first-degree or above nursing time and post and total length of hospital stay compared with group L (P <0.05).The incidence of postoperative infection in group L was higher than other two groups.Incidence of anastomosis leakage in group H was higher than that in other two groups (P <0.05).Conditions of compli-cations in group L were more severe and complicated compared with other two groups.Conclusion 3%≤SVV≤6% may increase the risk of postoperative infection and prolong the time of hospitalization.Patients in the level of 7%≤SVV≤10% may have a better postoperative recovery.This level could be a better goal of perioperative fluid therapy in elderly patients.
