Results: Our results showed that total parenteral nutrition (TPN) effectively mitigated weight loss on days 10 and 14 and the day before discharge, while also improving albumin (33.41 ± 4.57 in the control group, 34.87 ± 4.08 in the TPN group, p < 0.05; 33.72 ± 3.52 in the control group, 35.27 ± 4.04 in the TPN group, p < 0.05; 34.09 ± 4.44 in the control group, 35.55 ± 3.87 in the TPN group, p < 0.05) and prealbumin (245.18 ± 79.94 in the control group, 274.26 ± 86.73 in the TPN group, p < 0.05; 233.27 ± 79.57 in the control group, 279.34 ± 80.20 in the TPN group, p < 0.01;对照组的247.24±83.29,在同一时期,TPN组为280.65±100.22,p <0.05)。此外,非TPN和TPN组之间的CRBSI发生率或肝功能没有显着差异。此外,TPN组的住院时间较短(对照组为48.06±13.90,TPN组的42.13±14.22*,p <0.05),意外重新携带的发生率较低,对照组为37.1%(在对照组中为37.1%,在TPN组为21.4%,TPN组,P <0.05),P <0.05)。
