Summary

This trial aims to understand how medication used to treat low blood pressure during a Cesarean delivery can affect the uterine muscle tissue and its ability to contract in patients with Type II and gestational

Who is the study for?
This trial is for pregnant individuals with Type II or gestational diabetes who are undergoing an elective Cesarean delivery. They must be willing to provide uterine tissue samples during the procedure. There's no specific exclusion criteria provided, but typically those with conditions that may interfere with study results or pose a risk would not qualify.
What is being tested?
The study investigates how different vasopressors—Ephedrine, Phenylephrine, and Norepinephrine—affect the contraction of uterine muscles when given after childbirth to manage low blood pressure caused by spinal anesthesia in diabetic patients.
What are the potential side effects?
While this study focuses on uterine contractility rather than side effects, vasopressors can generally cause increased heart rate, anxiety, headache, and possible changes in blood flow to the uterus which will be studied.

Trial Design

8Treatment groups
Active Control
Group I: ControlActive Control1 Intervention
The myometrial samples are bathed in physiological salt solution (PSS) only.
Group II: Phenylephrine + oxytocinActive Control2 Interventions
The myometrial samples are bathed in physiological salt solution (PSS) with increasing concentrations of phenylephrine and oxytocin..
Group III: EphedrineActive Control1 Intervention
The myometrial samples are bathed in physiological salt solution (PSS) with increasing concentrations of ephedrine.
Group IV: PhenylephrineActive Control1 Intervention
The myometrial samples are bathed in physiological salt solution (PSS) with increasing concentrations of phenylephrine.
Group V: NorepinephrineActive Control1 Intervention
The myometrial samples are bathed in physiological salt solution (PSS) with increasing concentrations of norepinephrine.
Group VI: Control + oxytocinActive Control1 Intervention
The myometrial samples are bathed in physiological salt solution (PSS) and oxytocin.
Group VII: Ephedrine + oxytocinActive Control2 Interventions
The myometrial samples are bathed in physiological salt solution (PSS) with increasing concentrations of ephedrine and oxytocin..
