| NCT02654847 ↗ | Norepinephrine To Prevent Hypotension After Spinal Anesthesia For Cesarean Delivery: A Dose Finding Study | Completed | Samuel Lunenfeld Research Institute, Mount Sinai Hospital | N/A | 2016-01-01 | Spinal anesthesia is the most common anesthetic technique for elective Cesarean delivery (CD), but the most frequent unwanted side effect is hypotension, which can cause nausea and vomiting, as well as effects on the fetus. Prevention and treatment of maternal hypotension includes intravenous fluids and vasopressors. Phenylephrine is the most common vasopressor used for this purpose. However, it has been shown to reduce maternal heart rate and cardiac output, which may be a concern in an already compromised fetus. Norepinephrine is commonly used in high concentrations in intensive care and recent studies have suggested that in low concentrations it may be a better alternative to phenylephrine in elective CD, as it does not reduce the maternal heart rate or cardiac output. The optimum bolus dose of norepinephrine to prevent hypotension after spinal anesthesia in elective CD has not been elucidated. The investigators propose this study to determine the dose that would be effective in 90% of patients (ED90). A previous study by Ngan Kee et al, using continuous infusion of norepinephrine to prevent hypotension in elective CD, suggested a potency ratio for norepinephrine to phenylephrine of approximately 16:1. Hence, the investigators hypothesise that the ED90 will be approximately 6 µg, given that the current phenylephrine bolus dose at the investigators' institution is approximately 100 µg. |
| NCT02962986 ↗ | A Comparison of Intermittent Intravenous Boluses of Phenylephrine and Norepinephrine to Prevent Spinal-induced Hypotension in Cesarean Deliveries | Completed | Samuel Lunenfeld Research Institute, Mount Sinai Hospital | N/A | 2017-01-01 | Hypotension is a very common complication of spinal anesthesia for cesarean delivery, and can have unwanted side effects on both mother and fetus if not treated promptly. Phenylephrine has been the drug of choice to treat this spinal-induced hypotension. Although phenylephrine is safe to use for this indication, it has been associated with reflex bradycardia and a reduction in cardiac output. Norepinephrine is a potent vasopressor used to treat hypotension in the critical care setting. Recent studies have looked at norepinephrine's use in the obstetric setting, and have shown that it can be used safely and also has favourable hemodynamic properties when compared to phenylephrine, with less bradycardia and less depression of cardiac output. The investigators recently conducted a study to determine the ED90 of norepinephrine, and now plan to compare bolus doses of phenylephrine to norepinephrine for treating hypotension following spinal anesthesia for cesarean section. The investigators hypothesize that norepinephrine, when given as a bolus to prevent post spinal hypotension, will result in around 70% relative decrease in the rate of bradycardia when compared to phenylephrine in patients undergoing elective cesarean delivery under spinal anesthesia. |
| NCT03328533 ↗ | Norepinephrine Versus Phenylephrine Continuous Variable Infusion in Cesarean Delivery | Completed | Cairo University | Phase 4 | 2017-11-10 | 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 |
| NCT03706755 ↗ | Comparison of Two Doses of Norepinephrine in Preventing Hypotension After Spinal Anesthesia | Completed | University Tunis El Manar | Phase 4 | 2018-05-03 | The purpose of the study is to determine the more effective intravenous bolus of norepinephrine for maintaining blood pressure during a spinal anesthesia for a cesarean delivery with the fewer side effects. Low blood pressure has been shown to decrease uterine perfusion and foetal outcomes during cesarean delivery under spinal anesthesia. For elective or semi-urgent cesarean delivery, all participants will receive spinal anesthesia with a local anesthetic and either sufentanil or fentanyl. This study plans to enroll 124 pregnant women. Patients will be randomly assigned according to a computer generated system to be in one of two groups. |
| NCT05355974 ↗ | Using Vasopressor Medication to Support Blood Pressure During Intubation Procedure | Not yet recruiting | Wright State University | Phase 3 | 2022-06-01 | The purpose of this study is to investigate whether protocolized vasopressor use for patients with normal blood pressure undergoing rapid sequence intubation improves hemodynamic parameters and mitigates adverse events. The hypothesis is that use of vasopressors during Rapid Sequence Intubation will prevent substantial decreases in blood pressure when compared to normal intravenous fluids. |
| NCT05521152 ↗ | Norepinephrine for Prevention of Intraoperative Hypotension in Infants Undergoing Kasai Portoenterostomy | Recruiting | Kasr El Aini Hospital | Phase 3 | 2022-05-01 | This study aims to assess the efficacy and safety of prophylactic intraoperative norepinephrine infusion versus the standard technique on decreasing the incidence of intraoperative hypotension in infants undergoing Kasai portoenterostomy operation. |
