Abstract
Introduction: The Tanguieta funnel is a device used for intraoperative blood salvage in the abdomen in order to perform an auto transfusion in the context of ruptured ectopic pregnancies (EP) management. Developed in Saint Jean de Dieu Hospital in Tanguieta, it is the subject of this study whose objective is to describe the efficiency of this method in three pilot hospitals in Benin. Materials and method: It is a retrospective, descriptive and multicenter study which was carried out over a period of 5 years and it took place in three hospitals among which two teaching hospitals and a faith-based one. Results: Out of 38,252 deliveries, 567 cases of EP were identified that is to say 1.48%. Among these EPs, 337 cases were ruptured (59.4%) and among the ruptured EPs, 205 (60.8%) underwent an intraoperative auto transfusion. The rate of intraoperative blood salvage was 25% on average for the three centers. This rate was more than 75% for 28% of patients. Auto transfusion by intraoperative blood salvage was completed by homologous blood transfusion in 5.4% of cases. On admission, 45.9% of patients had a rate less than 7 g/dl as against 5.4% after auto transfusion. Hemoglobin was 6.7 g/dl on average on admission. The average hemoglobin at the 12th, 48th and 72nd post-operative hour was respectively 7.2 g/dl, 8.3 g/dl and 8.5 g/dl. In the post-operative period, 100 cases (48.8%) of anemia, one (1) case of fever, one (1) case of acute pulmonary Edema, one (1) case of state of shock were identified. Two (2) cases of death that is to say 0.97% of patients were mentioned in our study. The average length of hospital stay was five (5) days. Conclusion: The results are reassuring with the use of this autotransfusion technique after blood salvage by filtration and without lavage.
