Filter by:Prospective, randomized and controlled study who will be conducted at Maisonneuve-Rosemont hospital with the following objectives: To determine if an infusion of carbetocin over 10 minutes will reduce hemodynamic side effects, especially the peak of heart rate, in comparison to a rapid intravenous bolus (less than 2 seconds). To determine if an infusion of carbetocin will reduce the other side effects of duratocin in comparison to a rapid intravenous bolus. Study plans to enroll 70 adult patients scheduled to undergo elective cesarean delivery under spinal anesthesia. Half of the patient will receive Carbetocin 100 mcg intravenous as a bolus (less than 2 seconds) and the other half will receive Carbetocin 100 mcg intravenous infusion over 10 minutes.
The caesarean section is a frequently performed procedure in obstetrics and accounts for about 30% of all births in Germany. 55% to 68% of all caesarean sections are performed under spinal anesthesia. A possible side effect of spinal anesthesia is arterial hypotension with a prevalence of 70% to 80%. A placental hypoperfusion in the context of a reduced preload due to hypotension can reduce the fetal outcome. Early diagnosis and treatment of the hypotensive episode could reduce and at best prevent increased fetal morbidity. Due to their invasiveness due to the necessity of puncturing a distal artery of the extremity and the insertion of a catheter, established continuous blood pressure measurement procedures have disadvantages such as potential circulatory disorders of the hand, infections, bleeding and thrombosis and are therefore often not indicated in the context of an elective sectio. Non-invasive procedures such as NIBP, however, are discontinuous and may make a timely diagnosis of hypotension more difficult and delay therapy. The ClearSightTM system, which allows a continuous non-invasive blood pressure measurement, has been used in hip and knee joint surgery. There, a good correlation with invasive blood pressure measurements was found, particularly with regard to systolic and mean arterial pressure. An application in obstetrics has not yet been investigated. Due to the continuous measurement provided by ClearSightTM, continuous monitoring of blood pressure appears to be ensured, so that a faster reaction to previously undetected fluctuations in blood pressure can be expected compared to interval measurement.
Caesarean section is a risk factor for the development of neonatal respiratory complications, mostly respiratory distress syndrome (RDS) and transient tachypnoea of the new-born, both in term and preterm infants.
Presently, the standard of care at the investigators' practice is that the discharging physician decides the type and amount of opioid medication to prescribe a patient following a cesarean section. After informed consent has been obtained, patients will be enrolled in this randomized-controlled equivalence study. The experimental group will be prescribed 20 oxycodone-acetaminophen and the control group will be prescribed 28 oxycodone-acetaminophen at the time of discharge. Both groups will also be provided with a handout on non-opioid analgesia. The groups will be assigned randomly in blocks. The investigators will recruit patients either in the clinic, if participants are to have a scheduled cesarean section, or at some time during the hospital admission for delivery. The satisfaction survey and pain scale will be administered at the postoperative check by the clinic staff and providers. These surveys will be stored in a secure location at the clinic. If the patient does not show up for their postoperative visit, 3 attempts total will be made by an investigator to reach the patient and administer both surveys by phone within 2 weeks of discharge. A preliminary analysis of the data will be done once half the study patients have been recruited. The investigators do not foresee any threats to the external or internal validity of the study. The investigators are taking many measures to limit study bias. First, block randomization will help limit discrepancies between groups. Also, strict adherence to the inclusion and exclusion criteria will also help limit confounders that may make data difficult to interpret, such as non-opioid naïve patients and complications that may potentially increase pain and opioid requirements. Lastly, blinding of patients to the number of pills participants receive will help mitigate patient bias.
Comparison will be conducted between continuous variable infusions of Phenylephrine with starting dose of 0.75 mcg/Kg/min and Norepinephrine Bitartrate with starting dose of 0.1 mcg/Kg/min (with norepinephrine base of 0.05 mcg/Kg/min) for prophylaxis against Post-spinal hypotension during cesarean delivery
The aim of the present study is to quantify the dose and usage of sympathomimetics used in caesarean section.
The investigators will compare variable infusion of phenylephrine (at a starting rate of 0.75 mcg/Kg/min) with fixed rate (0.75 mcg/Kg/min which will stop of reactive hypertension occurred) and single shot (1.5 mcg/Kg) phenylephrine.
Norepinephrine has been recently introduced as a prophylactic vasopressor during Cesarean delivery with promising results ; However, the optimum dose for efficient prophylaxis with the least side effects is not known. In this study, we will compare three doses (0.05, 0.1, 0.15 mcg/Kg/min) of norepinephrine for prophylaxis against Post-Spinal hypotension during cesarean delivery.
three doses (0.025 mcg/Kg/min, 0.050 mcg/Kg/min, and 0.075 mcg/Kg/min) of norepinephrine will be compared for prophylaxis against Post-spinal anesthesia hypotension during Cesarean delivery.
Impedance Cardiography (ICG) is a non-invasive tool for continuous hemodynamic monitoring. Aims of our study is to assess the utility of ICG to evaluate the hemodynamic impact of 6 mg (GL6) vs 8 mg (GL8) levobupivacaine combined with fentanyl in healthy patients undergoing elective cesarean section; secondary, to compare the duration and quality of analgesia and anesthesia
