NCT07363109
The aim of this double-blind randomised study will be to compare a fixed-rate prophylactic metaraminol infusion to a fixed-rate prophylactic norepinephrine infusion during elective cesarean section under combined spinal-epidural anaesthesia.
NCT07037654
The goal of this clinical trial is to learn if drug ondansetron, used in lingual form, lowers the incidence of spinal anesthesia-induced hypotension in cesarean sections. It will also learn about the safety of drug ondansetron. The main questions it aims to answer are Does the drug ondansetron, used in lingual form, lower the incidence of spinal anesthesia-induced hypotension in cesarean sections? What medical problems do participants have when taking the drug ondansetron? Researchers will compare drug ondansetron to a placebo (a look-alike substance that contains no drug) to see if drug ondansetron works to reduce the incidence of spinal anesthesia-induced hypotension in cesarean sections Participants will: Take drug ondansetron or a placebo before induction of spinal anesthesia
NCT06668337
This randomized controlled trial aims to compare the effectiveness of different doses of ephedrine infusion in preventing maternal hypotension following spinal anesthesia in parturients undergoing cesarean sections. The study includes 120 participants, aged 18-40 years, with American Society of Anesthesiologists (ASA) physical status II, who are scheduled for elective cesarean delivery. The primary objective is to determine whether low-dose ephedrine infusions at 1.25 mg/min or 1.5 mg/min effectively reduce the incidence of maternal hypotension, with secondary outcomes assessing the need for rescue ephedrine, incidence of side effects (nausea, vomiting, tachycardia), and neonatal Apgar scores. Researchers will compare three groups-saline, 1.25 mg/min ephedrine, and 1.5 mg/min ephedrine-to evaluate their impact on maternal hemodynamic stability.
NCT06564935
Methodologies and approaches have been implemented with differing degrees of success to prevent neuraxial hypotension. Currently utilized approaches to prevent hypotension during spinal anesthetic administration consist of physical precautions such as leg restraints and compression hosiery, as well as sympathomimetic medications Through a competitive inhibition of noradrenaline uptake, heptaminol hydrochloride prevented orthostatic hypotension and increased the plasma concentration of noradrenaline. This inhibitory effect might account for a portion of the antihypotensive effect After thorough research of the literature, studies evaluating the role of preoperative oral heptaminol hydrochloride in preventing hypotension after spinal anesthesia in lower limb surgeries with tourniquets are lacking.

The prospective study is planned in a university hospital. Spinal anesthesia is widely used for cesarean section currently for its safety, low cost, reliability, easiness to administer, immediate effect, and well-operating conditions. However spinal anesthesia has some complications as hypotension, bradycardia and Post Dural Puncture Headache (PDPH). A practical strategy for avoiding hypotension during initiation of spinal anesthesia for cesarean delivery includes intravenous crystalloid, in conjunction with administration of vasopressors. PDPH is one of the most frequent complications of spinal anesthesia. Conservative therapies such as bed rest, hydration, and caffeine are commonly used as management. For this study, coffee group of patients will be given unsweetened brewed coffee 150 ml until 2-4 hours before surgery. Patients who accept to drink brewed coffee ( coffee group) and water( control group) will be included in the study. The patient's heart rate, blood pressure, oxygen saturation will be monitored and recorded during operation. Intraoperative will be recorded to amount of vasopressor and intraveous crystalloid. Whether the patient develops PDPH in the postoperative period will be followed for 3 days. In addition abdominal auscultation for bowel sounds hourly and the time of first bowel movements will be recorded. According to the patient's statement, the time of first flatulence and defecation will be followed and recorded.
NCT04396548
Neuraxial blockade such as spinal anaesthesia can cause severe hypotension due to pharmacological sympathectomy resulting in potential deleterious consequences for the patient. Prevention of this spinal anaesthesia induced hypotension is of utmost importance. Techniques currently in use for preventing hypotension include intravenous fluid prehydration, sympathomimetic drugs, and physical methods such as leg bindings and compression stockings. Midodrine is a direct acting α1-adrenoceptor agonist which causes venous and arterial vasoconstriction through stimulation of α1- receptors located in the vasculature. The aim of this study is to evaluate the efficacy and safety of prophylactic midodrine use with preoperative fluid hydration before spinal anesthesia in the prevention of hypotension in patients undergoing elective orthopedic surgery. We hypothesize that intraoperative hypotension would be less in patients given midodrine and intravenous fluid prehydration preoperatively before spinal anesthesia.
