RESUMEN
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 table:ScvO2 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.
RESUMEN
<p><b>OBJECTIVE</b>To observe the effects of electroacupuncture (EA) pretreatment on the intestinal function, inflammatory reaction and blood lactic acid in the patients of colorectal cancer surgery.</p><p><b>METHODS</b>Sixty patients of colorectal cancer laparotomy at selective period, aged from 18 to 59 years old were selected. According toⅠ-Ⅲ grade of American Society of Anesthesiologists (ASA), the patients were randomized into group A (total intravenous anesthesia), group B[total intravenous anesthesia combined with EA pretreatment at Zusanli (ST 36), Shangjuxu (ST 37) and Xiajuxu (ST 39) on the right side] and group C[total intravenous anesthesia combined with EA pretreatment at Zhongwan (CV 12), Tianshu (ST 25), Zusanli (ST 36), Shangjuxu (ST 37) and Xiajuxu (ST 39) on the right side], 20 cases in each one. The total intravenous anesthesia was applied to all of the three groups. EA pretreatment was used one day before surgery and 30 min before surgery at corresponding acupoints in the group B and group C separately, 30 min each time. After surgery, the recovery time of bowel sound, the recovery time of flatus, the recovery time of defecation, the duration of diet fasting, the time of peritoneal drainage tube withdrawal and the total peritoneal drainage volume were observed in the three groups. The venous blood was collected to determine white blood cell count (WBC) and neutrophil count (NEUT) before surgery (T), 24 h after surgery (T) and on the 5th day after surgery (T) separately. The arterial blood was collected to determine the level of lactic acid before surgery (T), after peritoneal douching (T) and 24 h after surgery (T)separately.</p><p><b>RESULTS</b>The recovery time of bowel sound, the recovery time of flatus, the duration of diet fasting and the time of peritoneal drainage tube withdrawal in the group C were apparently earlier than those in the group A (all<0.05). WBC and NEUT at Tin the group C were apparently less than those in the group A (both<0.05). The differences in lactic acid at T, Tand Twere not significant statistically in comparison of the three groups (all>0.05).</p><p><b>CONCLUSIONS</b>The total intravenous anesthesia combined with EA pretreatment at Zusanli (ST 36), Shangjuxu (ST 37), Xiajuxu (ST 39), Tianshu (ST 25) and Zhongwan (CV 12) reduce the recovery time of bowel sound, the recovery time of flatus, the duration of diet fasting and the time of peritoneal drainage tube withdrawal so as to improve the recovery of intestinal function, reduce WBC in 24 h after surgery and alleviate inflammatory reaction. This therapy has no influence on blood lactic acid.</p>
