There is an increasing need to fully understand the mechanisms that contribute to the higher blood loss after general anesthesia during cesarean section therefore it is important the investigators identify all pharmacological contributors to poor uterine tone. Furthermore, anesthesiologists are increasingly called upon to care for women undergoing a range of in-utero fetal surgeries which require a careful balanced anesthetic and strict control of uterine tone. This will be the first study that compares the three commonly used intravenous anesthesia agents on human myometrium: ketamine, etomidate and propofol. This study is required to allow doctors make informed decisions about which anesthesia agent is most suitable to manage their patient depending on clinical circumstances. The specific objective of this project is to investigate the pharmacological dose-response profiles of different anesthesia induction agents by in-vitro isometric tension measurements of contractions in gravid human myometrium. The investigators will study both spontaneous and oxytocin induced contractility.
