Preoperative autologous donation: what was the impact of the 1995 consensus statement?

Postpartum hemorrhage and transfusion of blood and blood components

Postpartum hemorrhage (PPH) is one of the top 5 causes of maternal mortality in developed and developing countries. The incidence of PPH is 40% after vaginal delivery and 30% after cesarean section. Criteria for PPH are based on the amount of blood loss. In clinical obstetrics, exact measurement of blood loss is often difficult. The most important treatment of PPH is red blood cell (RBC) transfusion. In the past few years, increasing concern has arisen about this treatment. Despite the introduction of several new guidelines, transfusion criteria still vary widely between clinicians. The decision whether to prescribe RBC transfusion is mostly based on postpartum hemoglobin (Hb) values. RBC transfusion should be aimed to reduce morbidity and especially to improve health-related quality of life (HRQoL). In this review, etiology, epidemiology, treatment, and prevention of postpartum hemorrhage are described. Special attention is given to the role of RBC transfusion in the treatment of PPH and the effects of RBC transfusion on HRQoL.

TARGET AUDIENCE

Obstetricians & Gynecologists, Family Physicians.

LEARNING OBJECTIVES

After completion of this article, the reader should be able to summarize the new guidelines related to transfusion criteria, explain the importance of reducing morbidity related to improving quality of life issues, and list infectious and noninfectious complications of a red blood cell transfusion.

Preoperative autologous blood donation by elderly patients undergoing orthopaedic surgery

BACKGROUND AND OBJECTIVES

To assess the feasibility of a programme of predeposit in elderly patients undergoing elective orthopaedic surgery.

PATIENTS AND METHODS

We retrospectively studied 789 elderly patient candidates (> 65 years of age) for orthopaedic surgery (total hip and knee replacement and spinal surgery), who were undergoing a programme of preoperative autologous blood donation (PABD) in our city hospital between January 1990 and December 1998.

RESULTS

Six hundred and eighty-eight patients (87.2%) were transfused with autologous blood; 128 (16.2%) also received allogeneic blood. Hip arthroplasty revision was characterized by the greatest blood consumption. The predeposit programme was discontinued in 96 patients (12.2%) because of the following complications: the onset of anaemia (11.0%); vasovagal reactions (0.5%); lack of venous access (0.4%); or cardiac complications (0.2%). No episodes of reaction to autologous transfusion were recorded.

CONCLUSIONS

Our study confirms the feasibility of PABD in elderly patients undergoing elective orthopaedic surgery.
