The Charité external cephalic version for leading twin breech without regional anesthesia and tocolysis. A prospective study on feasibility, sonographic assessment and outcomes.

OBJECTIVES: To assess the feasibility of external cephalic version (ECV) for the leading twin (twin A) in breech presentation in dichorionic and diamniotic twin pregnancies without the use of regional anesthetics and tocolysis and to characterize the sonographic parameters, maternal and neonatal outcomes. STUDY DESIGN: Prospective study performed in the Charité University Hospital outpatient obstetric department in Berlin, Germany. A total of 23 women from the 35th completed week of pregnancy with confirmed dichorionic-diamniotic twin pregnancy were recruited. ECVs were performed by the lead consultant for the breech and ECV clinic. Ethical approval provided by the Charité Ethics Commission (EA2/241/18). Demographic data were recorded. Fetal sonographic parameters were assessed. The success rate of ECV, duration of the ECV, gestational age at delivery, mode of delivery for both fetuses, maternal and neonatal outcomes were analyzed. RESULTS: Our main finding showed that ECV for twin A breech in dichorionic-diamniotic twins is successful in 56% (10/18) of cases without the need for regional anesthesia and without tocolysis. There is a significant increase in the spontaneous vaginal delivery rate for both twins of 95% (19/20) vs 12.5% (2/16) (p < 0.001). There is also a significant reduction in blood loss at delivery of 300 ml vs 500 ml (p = 0.034) in successful cases. CONCLUSIONS: We show that ECV for twin A in breech is feasible and in 56% (10/18) successful without regional anesthesia and tocolysis. The option of ECV for twin A breech should be offered to women.

The Windmill technique avoids manual removal of the retained placenta-A new solution for an old problem.

OBJECTIVE: The primary objective is to assess the reduction in manual removal of placenta with the Windmill technique of placenta delivery in patients with retained placenta. DESIGN: The Windmill technique involves the application of continuous 360° umbilical cord traction and rotation in such a manner as to be perpendicular to the direction of the birth canal at the level of the introitus. This rotation through 360° is repeated slowly with movement akin to the motion of the blades of a windmill. We performed a 3-year retrospective case-control study at the Charité University Hospital in Berlin. Patients with a retained placenta more than 30min following failed traditional interventions were consented and offered the Windmill technique of placenta delivery. Study cases were compared to controls where an operative manual removal of placenta was performed. Patients with suspected placenta implantation problems, uterine atony, bleeding due to vaginal tract injury and coagulation disturbances were excluded. RESULTS: Over the study period 14 patients were recruited to the study arm and 17 patients were in the control group. With the Windmill technique for retained placenta, 86% (12/14, p<0.001) of patients avoided invasive operative manual removal of the placenta in theatre. There was a statistically significant reduction in mean blood loss (429ml vs 724ml, p=0.001) and mean postoperative fall in hemoglobin values (1.3g/dl vs 2.5g/dl, p=0.04). There was a reduction in the time to delivery of the placenta, antibiotic prophylaxis and use of general anesthesia. CONCLUSION: The Windmill technique for the delivery of the retained placenta is a simple, safe, effective and easy to teach technique that reduces invasive operative manual removal of the placenta, postpartum blood loss and delay in the placenta delivery. This innovative technique can also be a lifesaving intervention especially in areas with limited or no access to operative facilities.
