Abstract:
Objective To investigate the effects of autologous blood transfusion on serum neopterin and IL-2 concentrations after radical gastrectomy. Methods Sixty ASA Ⅰ or Ⅱ patients of both sexes (33 male, 27 female) aged 40-65 yrs weighing 51-70 kg undergoing radical gastrectomy for stomach cancer were randomly divided into 2 groups (n = 30 each):homologous blood transfusion group (H) and autologous blood transfusion group (A). The patients were premedicated with intramuscular diazepam 10 mg and atropine 0.5 mg. Anesthesia was induced with midazolam 0.1 mg?kg-1, fentanyl 5 ?g?kg-1, propofol 1 mg?kg-1 and vecuronium 0.12 mg? kg-1 and maintained with isoflurane inhalation (1 % -2 %) and intermittent i. v. boluses of fentanyl and vecuronium. In group H homologous blood 400 ml was infused during gastro-intestinal anastomosis. In group A 400 ml of blood was removed from radial artery after induction of anesthesia, before surgery. Blood volume was maintained by simultaneous infusion of succinylated gelatin 500 ml. The 400 ml autologous blood was infused also during gastrointestinal anastomosis. Venous blood samples were taken before operation (baseline) , at the end of operation and on the 5th postoperative day for determination of serum concentrations of neopterin and IL-2 (ELISA) Results The two groups were comparable with regard to sex (M/F ratio), age, body weight, duration of operation and total blood loss. The serum concentrations of neopterin and IL-2 were significantly decreased after operation compared to the baseline values before operation in group H (P
