The Theory of Planned Behavior for the Improvement of the Delayed Blood Donation Cycle, Optimization of the Planning Behavior, and Donor Intention

The advances in the technology applied to the health field lead the medical system to be optimized and the medical equipment and drugs to be improved, and the benefits can be seen in the prolonged human lifetime. The increased age and the lifestyle, however, increase the demand of blood for medical procedures and to save lives. The average age of blood donors has gradually increased, the number of new blood donors has grown slowly, and the allocation of blood supply and inventory is complex and many times cannot be improved. The low increase in blood donor number is a concern that needs to be overcome. Here, the theory of planned behavior was used as a tool to analyze the motivation, intention, and behavior of blood donors. The theory of planned behavior was applied in the form of questionnaires to college students. The results indicated that participation on the research motivates and educates the participants to donate blood, encourages the behavior of relatives, and leads the participants to realize the altruistic and mutually beneficial outlook on blood donation. The results also indicated the awareness of the students with respect to the importance of blood donation and that it can be an important tool in order to educate and increase the young blood donor number.

Application of Salvage Autologous Blood Transfusion for treating Massive Hemorrhage during Ectopic Pregnancy

Purpose

To explore the application value of salvage autologous blood transfusion for massive hemorrhage occurring during ectopic pregnancy.

Methods

A retrospective analysis was performed on the basis of the clinical data of patients in our hospital for the period January 2019 to December 2021. These patients were confirmed to have suffered massive hemorrhage from an ectopic pregnancy during surgery and were treated with blood transfusion. The patients were divided according to their blood transfusion method into three groups: an autologous group (n = 46) treated with salvage autologous blood transfusion, a mixed group (n = 28) treated with salvage autologous + allogeneic blood transfusion, and an allogeneic group (n = 41) treated with allogeneic blood transfusion. The volume of intra-abdominal bleeding, the volume of autologous and allogeneic blood transfusion, postoperative fever and blood transfusion reaction, hemodynamic indices [systolic blood pressure (SBP), diastolic blood pressure (DBP), oxygen saturation (SpO2), and heart rate (HR)] before and after blood transfusion; 24-h postoperative blood routine [hematocrit (HCT), hemoglobin (Hb), platelets (PLT), red blood cells (RBCs)], and electrolyte indices (Na⁺, K⁺, Cl⁻) were all compared among the three groups.

Results

It was found that intra-abdominal bleeding volume in the autologous and mixed groups was higher than that in the allogeneic group (p < 0.05), and there was no statistical difference between the autologous and the mixed groups (p > 0.05). Autologous blood transfusion volume in the autologous group was higher than that in the mixed group (p < 0.05). Allogeneic blood transfusion volume in the allogeneic group was higher than that in the mixed group (p < 0.05). After blood transfusion treatment, the postoperative fever rates were 4.35%, 10.71%, and 19.51% in the autologous, mixed, and allogeneic groups, respectively, and the blood transfusion reaction rates were 0.00%, 3.57%, and 9.76%, respectively, which were lower in the autologous group than in the allogeneic group (p < 0.05). At 30 min after blood transfusion, SBP, DBP, and SpO₂ were higher in all three groups than before blood transfusion (p < 0.05), and HR was lower than before blood transfusion (p < 0.05), but there was no statistically significant difference between the groups at 30 min after blood transfusion (p > 0.05). At the 24- h postoperative period, no statistical difference was found when HCT, Hb, PLT, RBC, Na⁺, K⁺, and Cl⁻ were compared among the three groups (p > 0.05).

Conclusion

The use of salvage autologous blood transfusion for treating massive hemorrhage occurring during ectopic pregnancy is a safe and feasible method for rescuing patients with such condition because it can rapidly replenish the patient’s blood volume and save blood resources without causing postoperative hemodynamic, blood routine, and electrolyte abnormalities.
