Multifaceted spiral suture: A hemostatic technique in managing placenta praevia or accrete

Patients with total placenta previa and past history of cesarean delivery often experience overwhelming hemorrhage during childbirth. In order to control intraoperative and postoperative bleeding, we propose a novel multifaceted spiral suture of the lower uterine segment which directly sutures the bleeding site.To evaluate the efficacy and safety of multifaceted spiral suture, a retrospective s...

Spiral length design

On the circular curve, lateral acceleration affects comfort. On the spiral, both lateral acceleration and jerk affect comfort.  The determination of maximum curving speed on the basis of lateral acceleration only is not critical because the lateral acceleration is proportional to the square of speed whereas jerk is proportional to cubic power of speed. The maximum speed on a curve is thus signi...

ADJUSTABLE SUTURE IN STRABISMUS SURGERY

Adjustable suture in strabismus surgery is a way to get accurate alignment of the eyes after operation. This technique is used in cooperative patients, being either adults or children. We report the result of this technique in 120 patients, 70 with esotropia and 50 exotropia. The amount of deviation was between 20 and 60 prismdiopters. The patients were mostly adults and teenagers. and the...
