Clinical study: the impact of goal-directed fluid therapy on volume management during enhanced recovery after surgery in gastrointestinal procedures

Background: Goal-directed fluid therapy, as a crucial component of accelerated rehabilitation after surgery, plays a significant role in expediting postoperative recovery and enhancing the prognosis of major surgical procedures.Methods: In line with this, the present study aimed to investigate the impact of target-oriented fluid therapy on volume management during ERAS protocols specifically for gastrointestinal surgery. Patients undergoing gastrointestinal surgery at our hospital between October 2019 and May 2021 were selected as the sample population for this research.Results: 41 cases of gastrointestinal surgery patients were collected from our hospital over 3 recent years. Compared with T1, MAP levels were significantly increased from T2 to T5; cardiac output (CO) was significantly decreased from T2 to T3, and significantly increased from T4 to T5; and SV level was significantly increased from T3 to T5. Compared with T2, HR and cardiac index (CI) were significantly elevated at T1 and at T3-T5. Compared with T3, SVV was significantly decreased at T1, T2, T4, and T5; CO and stroke volume (SV) levels were increased significantly at T4 and T5. In this study, pressor drugs were taken for 23 days, PACU residence time was 40.22 +/- 12.79 min, time to get out of bed was 12.41 +/- 3.97 h, exhaust and defecation time was 18.11 +/- 7.52 h, and length of postoperative hospital stay was 4.47 +/- 1.98 days. The average HAMA score was 9.11 +/- 2.37, CRP levels were 10.54 +/- 3.38 mg/L, adrenaline levels were 132.87 +/- 8.97 ng/L, and cortisol levels were 119.72 +/- 4.08 ng/L. Prealbumin levels were 141.98 +/- 10.99 mg/L at 3 d after surgery, and 164.17 +/- 15.84 mg/L on the day of discharge. Lymphocyte count was 1.22 +/- 0.18 (109/L) at 3 d after surgery, and 1.47 +/- 0.17 (109/L) on the day of discharge. Serum albumin levels were 30.51 +/- 2.28 (g/L) at 3 d after surgery, and 33.52 +/- 2.07 (g/L) on the day of discharge.Conclusion: Goal-directed fluid therapy (GDFT) under the concept of Enhanced Recovery After Surgery (ERAS) is helpful in volume management during radical resection of colorectal tumors, with good postoperative recovery. Attention should be paid to the influence of pneumoperitoneum and intraoperative posture on GDFT parameters.
