Effect of goal-directed fluid therapy guided by SVV on gastrointestinal function in patients undergoing resection of gastrointestinal tumor / 临床麻醉学杂志

ABSTRACT

Objective To investigate the effect of SVV guided fluid therapy on blood gas and lipopolysaccharide (LPS),procalcitonin (PCT) in patients undergoing resection of gastrointestinal tumor.Methods Sixty patients aged 60 85 years from Jan,2016 to Feb,2017 falling into ASA physical status Ⅱ or Ⅲ,scheduled for elective radical operations for gastrointestinal cancers,were includ ed and randomly divided into two groups (n =30 each) using a random number tableScvO2 guided fluid therapy (group C),SVV guided fluid therapy (group G).MAP,HR and CVP of patients were recorded at the same time before anesthesia (T0),tumor removal (T1) and the end of surgery (T2)respectively.PH,BE,HCO3-and Lac of venous blood samples and artery blood samples at T0-T2,6 hours after surgery(T3) were recorded.Venous blood samples were collected at T0,T3 to detect LPS and PCT.Crystalloid requirements,colloid requirements,total volume,bleeding volume,peritoneal fluid volume and the use of dopamine were recorded.The time of PACU,time when the patients first exhausted and was fed after operation,length of hospital stay after operation were recorded.Results Compared with group C,BE of artery blood was obviously increased at T2,T3 in group G (P＜0.05);the Lac of artery at T2 and the Lac of artery and venous blood at T3 in group G was obvi ously decreased.LPS and PCT were decreased at T3 in group G (P＜0.05).Compared with group C,the needed colloid was increased in group G,the needed crystalloid and total volume of fluid infused were decreased in group G (P＜0.05).Compared with group C,the time of PACU starting to exhaust and feed,length of hospital was shortened in group G (P＜0.05).Conclusion SW guided goal directed fluid therapy is more conductive to maintain the acid base and reduce the incidence of in fection for the patients with gastrointestinal tumor operation,promote the recovery of gastrointestinal function and decrease the length of hopital after operations.
