Objective:To explore the clinical effect of fluid management strategy guided by lung ultrasound (LUS) during laparoscopic radical resection of colon cancer.Methods:A total of 96 patients with colon cancer diagnosed and treated in Suzhou Hospital Affiliated to Anhui Medical University (Suzhou Municipal Hospital) from November 2020 to April 2023 were retrospectively selected as the study objects, and they were divided into the control group and the study group by different treatment methods, with 48 cases in each group. Both groups underwent laparoscopic radical resection of colon cancer, the control group was given conventional fluid therapy during the operation, and the study group was given LUS-guided fluid therapy strategy. The fluid intake and outflow, postoperative rehabilitation, hemodynamic indexes and tissue perfusion indexes at different time points were compared between the two groups.Results:The intake of crystal and colloid in the study group were less than those in the control group: (1 039.84 ± 227.45) ml vs. (1 245.36 ± 241.87) ml, (598.63 ± 110.92) ml vs. (697.84 ± 135.21) ml, there were statistical differences ( P<0.05). The spontaneous breathing time and time to open eyes upon command in the study group were shorter than those in the control group: (14.26 ± 1.71) min vs. (16.30 ± 1.95) min, (19.32 ± 2.25) min vs. (22.86 ± 2.69) min, there were statistical differences ( P<0.05). At the end of surgery, the heart rate and mean arterial pressure in the study group were lower than those in the control group, while the cerebral oxygen saturation and central venous oxygen saturation were higher than those in the control group: (84.20 ± 7.19) beats/min vs. (87.41 ± 7.60) beats/min, (88.74 ± 7.21) mmHg (1 mmHg = 0.133 kPa) vs. (92.33 ± 7.65) mmHg, (76.33 ± 4.91)% vs.(73.15 ± 5.16)%,(81.16 ± 4.77)% vs.(79.16 ± 4.50)%, there were statistical differences ( P<0.05). Conclusions:The fluid therapy strategy guided by LUS can ensure adequate tissue perfusion, stabilize hemodynamics, and promote postoperative recovery.
