A Prospective Comparison of TL-400 and NICOM for Goal-Directed Fluid Therapy in Gastrointestinal Tumors Surgery
Abstract Objective: Goal-directed fluid therapy (GDFT) based on NICOM(CheetahMedical, Vancouver, Washington) was highly associated with improved postoperative prognosis, but has several limitations. T-Line-400(TL-400, TensysMedical, San Diego, California) which is an emerging non-invasive hemodynamic monitor may be applicable for GDFT. Thus, the trial was to determine whether GDFT based on TL-400, when compared to GDFT based on NICOM, would lead to similar outcomes on patients undergoing gastrointestinal tumor resection.Methods: 100 patients who underwent laparoscopic resection of gastrointestinal tumors in Yongchuan Hospital of Chongqing Medical University from October 2020 to May 2021 were randomized into either TL-400 GDFT group (group T) or NICOM GDFT group (group N). The intraoperative fluid volume and the postoperative complications within 30 days were recorded.Results: There were no significantly statistical differences between groups with respect to the total fluid volume (2360 ±282ml vs 2295 ±223ml), the colloid volume (1167±153ml vs 1126±109ml), the crystalloid volume(1193 ±156ml vs 1173±157ml). Both GDFT based on TL-400 and NICOM strategies were equivalent for the first flatus(57.3±7.9 vs 58.5±8.5hours), wound healing time(11.2 ±1.2days vs 10.9±1.1days) and LOS(hospital length of stay) (13.3±1.4days vs 13.1±1.2days). In addition, the TL-400 had less data missing than the NICOM.Conclusion: TL-400 performs similarly to NICOM in guiding GDFT, with no significant differences in perioperative fluid infusion and postoperative prognosis in patients undergoing gastrointestinal tumor resection. Compared with NICOM, TL-400 can avoid the interference of electrocoagulation and can capture more data.Trial registration: This study has been registered on the Chinese Clinical Trial Registry (ChiCTR2100046350) (http://www.chictr.org.cn/index.aspx).
