ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the effect of compound branch chain amino acid(BCAA) injection on nutritional support in patients after radical resection for colorectal cancer.</p><p><b>METHODS</b>Fifty patients with radical resection for colorectal cancer were randomly divided into two groups, and received compound branch chain amino acid (n=25) or compound amino acid(n=25) as control per day from postoperative day(POD)1 to POD 7. The levels of total protein, albumin, pre-albumin, transferring, nitrogen balance and complications were compared between the two groups.</p><p><b>RESULTS</b>On POD 8, the levels of albumin, pre- albumin, transferring were (36.12+/-3.16)g/L, (237.10+/-37.29)mg/L, and (2.18+/- 1.34)g/L in study group, and (30.61+/-3.55)g/L, (191.73+/-27.60)mg/L, and (1.71+/-0.84)g/L respectively in the control group(all P< 0.05). Nitrogen balance increased significantly from POD5, and increased to normal on POD 6 in study group, significantly higher than that in the control group (9.91+/-6.53 vs - 9.73+/-11.21, P=0.024). The complication rate of incision infection and delayed healing was 8.3% in study group, significantly lower than 38.1% in the control group(P< 0.05).</p><p><b>CONCLUSION</b>Compared with compound amino acid, compound branch chain amino acid injection can reduce proteolysis, correct negative nitrogen balance and promote wound healing.</p>
