[Clinical Application of Preoperative Autologous Blood Donation in Selective General Surgery].

Objective: To study the clinical effects of preoperative autologous blood donation (PABD) in selective general surgery.

Methods: Paired study was performed in PABD group with 70 PABD cases screened from selective general surgery during the period from November 2017 to August 2018 in our hospital, and the control group included 70 cases without preoperative autologous blood donation, the baseline data before surgery were not significantly different. The transfusion quantities of allogeneic RBC and plasma, the levels of perioperative hemoglobin and platelets, the time and expense of hospitalization were compared between two groups.

Results: The levels of Hb and Plt in PABD group before and after blood collection were determined as follows: 138.26±14.73 g/L vs 127.52±13.36 g/L (P＜0.05) and (221.67±52.86)×10/L vs (198.35±52.65)×10/L (P＞0.05) respectively. The analysis of allo-RBC and allo-plasma transfusion in PABD group and control group showed that: the quantity of allogeneic RBC transfusion was 0.20±0.71 U and 0.89±0.97 U, and the quantity of allogeneic plasma transfusion was 30.43±100.81 ml and 106.52±152.61 ml (P＜0.05) respectirdy during perioperation. The comparison results of preoperative Hb and plt in PABD group and control group were 135.65±14.16 g/L vs 134.15±11.98 g/L and (270.36±58.28)×10/L vs (271.67±65.02) ×10/L respectively. The levels of postoperative Hb and plt in PABD group and control group were 120.24±14.40 g/L vs 121.20±14.30 g/L at 1 d after operation, and (241.80±63.58)×10/L vs (241.30±69.11)×10/L at 1 d after operation respectively; 123.15±13.80 g/L vs 121.65±14.33 g/L at 3 d after operation and (251.26±72.94)×10/L vs (255.54±73.85)×10/L at 3 d after operation; 122.78±13.92 g/L and 122.00±13.82 g/L (before discharge) and (262.50±80.96)×10/L and (264.56±71.08)×10/L (before discharge, platelet). These data were not statistically different (P＞0.05). The hospitalization time was 14.84±3.37 days and 14.84±2.24 days, respectively, without statistical difference (P＞0.05) in two groups. The expenses of hospitalization and the blood transfusion in two groups were 50627.27±9889.45 RMB and 50979.43±8195.00 RMB; 354.39±362.57 RMB and 684.02±425.53 RMB (P＜0.05).

Conclusion: The application of PABD reduces the use of allogeneic blood and costs for patients undergoing selective surgery with blood losts of 1000 ml.
