Background and Aims: Although spinal anaesthesia (SA) is nowadays the preferred anaesthesia technique for caesarean section (CS), it is associated with considerable haemodynamic effects, such as maternal hypotension. This study aimed to evaluate a wide range of variables (related to parturient and anaesthesia techniques) associated with the incidence of different degrees of SA-induced hypotension during elective CS. Methods: This prospective study was conducted on 511 mother-infant pairs, in which the mother underwent elective CS under SA...

We report a case of combined severe aortic stenosis and regurgitation in a pregnant patient with a history of congenital bicuspid aortic valve. The patient presented at 22 weeks of gestation with angina and pre-syncopal symptoms. During her admission, she experienced intermittent episodes of non-sustained ventricular tachycardia and hypotension. A multi-disciplinary healthcare team was assembled to decide on the appropriate medical and surgical treatment options. At 28 weeks of gestation, the patient underwent a caesarean delivery immediately followed by a mechanical aortic valve replacement...

Neuraxial clonidine improves postoperative analgesia in the general surgical population. The efficacy and safety of neuraxial clonidine as a postoperative analgesic adjunct in the Caesarean section population still remains unclear. This systematic review and meta-analysis aims to evaluate the effect of perioperative neuraxial clonidine on postoperative analgesia in women having Caesarean section under neuraxial anaesthesia. We included randomized controlled trials comparing the analgesic efficacy of the perioperative administration of neuraxial clonidine alone or in combination with a local anaesthetic and/or opioids in women having elective Caesarean section under neuraxial anaesthesia when compared with placebo...

Several techniques have been proposed to prevent hypotension in obstetric patients. Ephedrine and phenylephrine are individually used to prevent maternal hypotension; however, each has its own drawbacks. Some researchers have reported that the infusion of combined ephedrine and phenylephrine immediately after spinal anesthesia for cesarean delivery reduces the incidence of maternal hypotension. Other studies have indicated that the combination is not superior to the infusion of an individual agent. The present study aimed to evaluate the effect of prophylactic infusion of ephedrine and phenylephrine before the induction of spinal anesthesia for cesarean section on maternal hemodynamic...

BACKGROUND: Hypotension is a common side effect of spinal anaesthesia during caesarean delivery and is associated with maternal and foetal adverse effects. We developed an updated double intravenous vasopressor automated (DIVA) system that administers phenylephrine or ephedrine based on continuous noninvasive haemodynamic monitoring using the Nexfin device. OBJECTIVE: The aim of our present study is to compare the performance and reliability of the DIVA system against Manual Vasopressor Bolus administration...

BACKGROUND: Post-spinal hypotension is a common maternal complication during cesarean delivery. Aortocaval compression by the gravid uterus has been assumed as a precipitating factor for post-spinal hypotension. The role of left lateral tilting position in improving maternal cardiac output after subarachnoid block (SAB) is unclear. The aim of this work is to investigate the effect of left lateral tilting on maternal hemodynamics after SAB. METHODS: A prospective observational study was conducted including 105 full term pregnant women scheduled for cesarean delivery...

Vitamin D (VD) has exhibited immunomodulatory role in the pathogenesis of preeclampsia. We hypothesize VD potentiate nifedipine treatment for preeclampsia by shortened the time to control blood pressure and prolong time before subsequent hypertensive crisis. We conduct a randomized trial of 683 primigravid women with preeclampsia, who were assigned to different treatment groups, either nifedipine+placebo or nifedipine+VD orally, by random after screening. Primary endpoints include time to control hypertension and time before another hypertensive crisis...

PURPOSE: Hypotension is common after spinal anesthesia for Cesarean delivery. It is associated with nausea, vomiting, and fetal acidosis. Previous research on phenylephrine excluded obese subjects. We compared the incidence of intraoperative nausea and vomiting (IONV) in obese patients who received a prophylactic phenylephrine infusion vs those who received bolus dosing for the treatment of spinal-induced hypotension. METHODS: In this multicentre, double-blinded randomized controlled trial, 160 obese women undergoing elective Cesarean delivery under spinal anesthesia were randomized to receive a prophylactic phenylephrine infusion initiated at 50 μg·min-1 (and titrated according to a predefined algorithm) or 100 μg phenylephrine boluses to treat hypotension...

This study sought to compare postpartum blood loss and maternal outcomes after 3IU and 5IU oxytocin at elective caesarean delivery. In a prospective observational study, 73 women undergoing elective caesarean delivery under spinal anaesthetic received a slow I.V. injection of either 3IU (n = 35) or 5IU (n = 38) oxytocin after delivery. The main outcome was gravimetrically measured 24-hour postpartum blood loss with a non-inferiority margin of 300 mL. Uterine tone, phenylephrine dose, emesis and hypotension after oxytocin administration were secondary outcomes...

OBJECTIVE: To test the hypothesis that increasing the intravenous fluid bolus volume at the time of epidural placement in women with narrow pulse pressure would reduce postepidural fetal heart rate (FHR) abnormalities, hypotension, and resuscitative obstetric interventions. METHODS: We performed a single-center randomized controlled trial. Eligible participants were normotensive with a nonanomalous singleton gestation at or after 35 weeks and with a narrow pulse pressure (less than 45 mm Hg) on admission...

Although angiotensin II receptor blockers (ARBs) are contraindicated during pregnancy, new cases are currently being reported.A 32-week preterm neonate was admitted after C-section due to maternal oligohydramnios. He presented with Potter phenotype, pulmonary hypoplasia with pneumothorax, systemic hypotension and anuria. He required chest drain insertion and continuous positive airway pressure (CPAP), volume expansion plus inotropic support with persistent renal failure. Mother confirmed olmesartan intake during entire pregnancy...

OBJECTIVE(S): Every year in France, 10% to 20% of the 600 000 women given epidural analgesia during labor experience hypotension, which in 15% of cases is associated with fetal heart rate abnormalities. The efficiency of lower limbs venous compression in preventing the occurrence of maternal hypotension after neuraxial anesthesia has already been demonstrated, but only in the context of scheduled cesarean section. We assessed the preventive effect of medical lower limbs venous compression on the incidence of maternal hypotension after epidural analgesia during spontaneous term labor...

Sepsis is the leading cause of direct maternal mortality, but there are no data directly comparing the response to sepsis in pregnant and nonpregnant (NP) individuals. This study uses a mouse model of sepsis to test the hypothesis that the cardiovascular response to sepsis is more marked during pregnancy. Female CD1 mice had radiotelemetry probes implanted and were time mated. NP and day 16 pregnant CD-1 mice received intraperitoneal lipopolysaccharide (LPS; 10 μg, serotype 0111: B4). In a separate study, tissue and serum (for RNA, protein and flow cytometry studies), aorta and uterine vessels (for wire myography) were collected after LPS or vehicle control administration...

BACKGROUND: Spinal anaesthesia carries a risk of hypotension. We hypothesized that pleth variability index and perfusion index would assess maternal volume status, and thus, allow identification of patients at higher risk of developing hypotension after spinal anaesthesia for caesarean delivery. METHODS: Fifty patients undergoing elective caesarean delivery were enrolled. All patients received spinal anaesthesia with 0.5% hyperbaric bupivacaine (10 mg) and fentanyl (10 mcg)...

Hypertensive disorders affect about one third of all people aged 20 and above, and are treated with anti-hypertensive drugs. Preeclampsia (PE) is one form of such disorders that only develops during pregnancy. It affects ten million pregnant women globally and additionally causes fetal loss and major newborn disabilities. The syndrome's origin is multifactorial, and anti-hypertensive drugs are ineffective in treating it. Biomarkers are helpful for predict its development. Generic drugs, such as low dose aspirin, were proven effective in preventing preterm PE...

Spinal anaesthesia for elective caesarean section is associated with maternal hypotension, secondary to alteration of sympathetic tone and hypovolemia, in up to 70% of cases. Measurement of the subaortic variation in the velocity time integral (VTI) after passive leg raising allows prediction of fluid responsiveness. Our objective, in this prospective single-centre observational study, was to assess the ability of change in VTI after 45° passive leg raising to predict hypotension after spinal anaesthesia. Ultrasound measurements were performed just before elective caesarean section...

BACKGROUND: Maternal inhalation of 35-40% oxygen concentration has no significant effect on foetal partial pressure of oxygen, and 60-100% produced maternal and foetal hyperoxia with increased free radical activity. The benefit of 50% maternal oxygen inhalation on foetal oxygenation, oxidant stress and total antioxidant status (TAS) during Caesarean section (CS) has not been simultaneously evaluated. METHODS: In this prospective, randomized, controlled trial 120 ASA physical status I-II, term pregnant women were recruited to elective CS (n = 60) and emergency CS (n = 60) and received either 50% oxygen or air inhalation following subarachnoid block (SAB)...
