Carboprost tromethamine prevents caesarean sectionassociated postpartum hemorrhage

Purpose: To investigate the effect of carboprost tromethamine on post-partum hemorrhage associated with caesarean section.Methods: One hundred patients with postpartum hemorrhage induced by cesarean section who were admitted to Binzhou People’s Hospital from October 2016 to August 2018 were selected. They were randomly assigned to two groups: control group and treatment group. Patients in the control group were administered oxytocin, while those in the treatment group received oxytocin in combination with carboprost tromethamine. The incidence of hemorrhage and adverse reactions were compared for the two groups.Results: The two groups showed gradually increasing degrees of postpartum hemorrhage within 24 h, but the treatment group had significantly lower volume of postpartum hemorrhage than the control group at different time points (p < 0.05). At the 1st, 3rd and 5th days after delivery, the height of the uterine fundus decreased gradually in the two groups, but was smaller in the treatment group than in the oxytocin group at all time points (p < 0.05). Total response in the treatment group was 98 %, which was significantly higher than 78 % in the control group (p < 0.05). The incidence of adverse reactions in the treatment group (12 %) was significantly lower than that in the control group (24 %, p < 0.05).Conclusion: Carboprost tromethamine prevents postpartum hemorrhage after cesarean section. It effectively reduces bleeding and promotes uterine involution, without obvious adverse reactions. Keywords: Carboprost tromethamine, Oxytocin, Cesarean section, Postpartum hemorrhag

Optimal View Angle in Collective Dynamics of Self-propelled Agents

We study a system of self-propelled agents in which each agent has a part of omnidirectional or panoramic view of its sensor disc, the field of vision of the agent in this case is only a sector of a disc bounded by two radii and the included arc. The inclination of these two radii is characterized as the view angle. Contrary to our intuition, we find that, the non-omnidirectional-view for swarm agents with periodic boundary conditions in noiseless Vicsek model can accelerate the transient process of the emergence of the ordered state. One consequent implication is that, there are generally superfluous communications in the Vicsek Model, which may even obstruct the possible fast swarm emergence. This phenomenon may invoke further efforts and attentions to explore the underlying mechanism of the emergence in self-propelled agents.Comment: 4 pages, 6 figure
