Carbetocin (Duratocin®) is a long-acting form of oxytocin, with a half-life almost 10 times longer. Studies have demonstrated that carbetocin diminishes the need for secondary uterotonic agents compared to oxytocin for cesarean delivery (CD). Despite certain Canadian guidelines recommending its use for elective CD, several Canadian centers and other countries have not adopted carbetocin. The purpose of this study is to prospectively gather electronic data on all CDs over a one year period, elective and emergent, in a single institution, and to evaluate the efficacy and other clinical outcomes when carbetocin is used as a first line uterotonic for all CDs. A database using Microsoft Dynamics CRM is available on smart phones and tablets. Data regarding additional uterotonic use and impact of carbetocin use during CD on intra and postoperative outcomes are gathered and analyzed. The primary outcome is the use of additional uterotonics in this population compared to that described in the literature for oxytocin as the primary uterotonic.
Spinal anesthesia for caesarean section is associated with a decrease in systemic vascular resistance and cardiac output and may cause hypotension in a significant portion of the parturients. Hypotension during delivery may cause maternal and fetal complications. If parturients who are likely to develop hypotension after spinal anesthesia can be identified before surgery, anesthesiologists would have opportunity to take measures such as prophylactic vasopressor administration. Perfusion index (PI) measured by pulse oximetry reflects vasomotor tone which affects the degree of hypotension after spinal anesthesia. This is a non-invasive method of assessing the relative vascular tone with the use of pulse oximeter which calculates the ratio of pulsatile versus the non-pulsatile component of the blood flow. A lower PI indicates greater peripheral vasomotor tone. Pleth variability index (PVI) is calculated using maximum and minimum values of perfusion index during respiratory cycles. PVI is one of the dynamic indices that can predict fluid responsiveness. There are several studies investigating the predictive value of finger PI and PVI on hypotension after spinal anesthesia. However the aortocaval compression by the gravid uterus directly effects the lower extremity perfusion. So, in this study we aimed to investigate whether the right toe PI and PVI values at supine and left lateral positions can predict hypotension during caesarean section.
Previous research has suggested that cesarean section may be associated with an increased risk of developing obesity in childhood, adolescence and adulthood. Yet, previous studies have been small or unable to differentiate between elective and non-elective cesarean section. Therefore, using a population-based cohort the purpose is to examine the associations between vaginal delivery, elective and non-elective cesarean section on the risk of developing obesity in young adulthood among Swedish young singleton males. Using the Swedish medical birth registry, the recorded mode of delivery and indication of delivery which will be matched to those males who perform military conscription, where their body mass index is recorded. The investigators hypothesize that there will be an elevated risk of obesity in those born with non-elective cesarean section, as a function of confounding, while those born with elective cesarean section will not have a higher risk of obesity than those born with vaginal delivery.
This will be an open label pilot randomized controlled clinical trial. Women undergoing cesarean delivery will be randomized to have standard wound dressing care or chlorohexidine gluconate (CHG) impregnated wound dressing (ReliaTect™ Post-Op Dressing).
In this pilot study, investigators will administer calcium chloride or placebo to pregnant women undergoing Cesarean delivery who have been identified as high risk for hemorrhage due to poor uterine muscle contraction, or atony. They will assess whether a single dose of calcium given immediately after the delivery of the fetus decreases the incidence of uterine atony and bleeding for the mother. The pharmacokinetics of calcium chloride in pregnant women will also be established. Data from this pilot study of 40 patients will be used to determine sample size and appropriateness of a larger randomized clinical trial.

Comparison between prophylactic continuous variable infusion of phenylephrine (starting dose 0,5mcg/kg/min) and norepinephrine tartrate (starting dose 0,1mcg/kg/min) to prevent hypotension and maintain cardiac output under spinal anesthesia during cesarean delivery.
The aim of this double-blind randomized study will be to compare a fixed-rate prophylactic noradrenaline infusion to a fixed-rate prophylactic phenylephrine infusion during elective cesarean section under combined spinal-epidural anesthesia
Compare 0.05 μg/kg/min Norepinephrine and 0.25 μg/kg/min phenylephrine effect on fetus and parturient during Cesarean Section
