OXT and pulmonary arterial hypertension: While standard uterotonic likeoxytocin have been utilized to prevent PPH, they possess certain limitations, such as a shorter half-life, a reduced contraction length,and a greater incidence of side effects such as fluid overload, convulsions, arrhythmia, and pulmonary edema [4].However, the cold chain required for preserving oxytocin is not sufficiently maintained in many places, including our own nation,increasing the risk of treatment failure [5].
