Placental protein 13 (PP13) induces hypotension in rats. This study aims to evaluate PP13 effects on isolated uterine arteries from nonpregnant and mid-pregnant rats. Vessels were isolated, cannulated, and pressurized to 50 mmHg within an arteriograph, preconstricted and exposed to increasing PP13 concentrations (10(-13)-10(-8) M). PP13 elicited 38-50% arterial vasodilation with half-maximum response (EC50) = 1 pM. The relaxation was mediated by activating the endothelial-signaling pathways of prostaglandin and nitric oxide (NO)...

The aim of the study was to investigate the effects of ephedrine intrathecal injection on maternal thermodynamics and spinal nerve block in cesarean section. A total of 107 patients undergoing elective cesarean section under combined spinal epidural anesthesia were randomly divided into two groups: group E: Bupivacaine (6 mg) combined with ephedrine (15 mg) and group C: Bupivacaine (6 mg). Systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), the incidence of hypotension, hypertension, tachycardia, nausea and vomiting were all recorded...

BACKGROUND: Maternal hypotension is a common complication after spinal anesthesia for cesarean section (CS). In this study we investigated the role of leg elevation (LE) as a method for prevention of post-spinal hypotension (PSH) for cesarean section. METHODS: One hundred and fifty full term parturients scheduled for CS were included in the study. Patients were randomized into two groups: Group LE (leg elevation group, n = 75) and group C (Control group, n = 75)...

BACKGROUND AND AIMS: While ephedrine was the preferred drug for treating spinal-induced hypotension in pregnancy, its use has declined because of resultant fetal acidosis. The objective of this randomized control trial was to compare the effects of a slow and rapid bolus of ephedrine on fetal acidosis, maternal blood pressure, and heart rate (HR) during cesarean section performed under spinal anesthesia. MATERIAL AND METHODS: Eighty full-term parturients scheduled for cesarean section under spinal anesthesia were randomly allocated into two groups...

Fracture management in pregnant patients is challenging. Anatomic and physiologic changes in pregnancy increase the complexity of treatment. Maternal trauma increases the risk of fetal loss, preterm birth, placental abruption, cesarean delivery, and maternal death. Initial resuscitation and treatment in a facility equipped to handle the orthopaedic injury and preterm births are paramount. Pelvic and acetabular injuries are potentially life threatening. The benefits and risks of surgical treatment must be carefully considered...

Spinal needles with different diameters can be used to prevent side effects in patients undergoing spinal anaesthesia. However, the velocity of local anaesthetic changes through the spinal needle depending on the diameter of it. Local anaesthetic injection velocity has been reported to be associated with the spinal block level. We aimed to compare spinal needles of different diameters with the same local anaesthetic volumetric flow rate in terms of spinal blockade and hemodynamics in obstetric patients. Eighty-four patients received spinal anaesthesia by either a 25G needle or 29G with the same volumetric flow rate...

BACKGROUND: After spinal anesthesia, patients undergoing cesarean section are more likely to develop hemodynamic changes. The baricity of local anesthetic has an important role on spinal blockade effects. The aim of this study was to compare the isobar and hyperbaric bupivacaine 0.5% plus fentanyl on maternal hemodynamics after spinal anesthesia for C/S. METHODS: In this double-blind study, 84 healthy pregnant women undergoing C/S using bupivacaine 0.5% isobar (study group, n=42) or hyperbaric (control group, n=42) for spinal anesthesia were scheduled...

Prophylactic vasopressor administration is commonly recommended to reduce maternal hypotension during spinal anaesthesia for caesarean section. Metaraminol has undergone limited investigation in obstetric anaesthesia for this purpose, particularly in comparison with phenylephrine. In this multicentre, randomised, double-blind, non-inferiority study, we compared prophylactic phenylephrine or metaraminol infusions, started immediately after spinal anaesthesia, in 185 women who underwent elective caesarean section...

BACKGROUND: The use of phenylephrine as the first-line agent for prevention and treatment of maternal hypotension during cesarean delivery (CD) may reduce cardiac output, posing a theoretical risk to mother and fetus. Norepinephrine has been suggested as a potential alternative, because its β-adrenergic effects might result in greater heart rate and cardiac output than phenylephrine. The use of norepinephrine to prevent and treat hypotension during CD is new, and its use as a bolus has not been fully determined in this context...

Amniotic fluid embolism (AFE) is recognized as a type of syndrome characterized by the abrupt onset of hypoxia, hypotension, seizures, or disseminated intravascular coagulopathy (DIC), occurring during labor, delivery, or immediately postpartum, caused by the inflow of amniotic components into the maternal circulation. AFE is a rare condition but one of the most serious obstetrical complications, resulting in a high mortality rate among pregnant women. Despite earlier recognition and intensive critical management, we often encounter patients who unfortunately do not recover from the exacerbation of AFE-related conditions...

BACKGROUND: The dural puncture epidural (DPE) technique is a modification of the combined spinal epidural (CSE) technique, where a dural perforation is created from a spinal needle but intrathecal medication administration is withheld. The DPE technique has been shown to improve caudal spread of analgesia compared with epidural (EPL) technique without the side effects observed with the CSE technique. We hypothesized that the onset of labor analgesia would follow this order: CSE > DPE > EPL techniques...

OBJECTIVE: Lumbosacral cerebrospinal fluid volume is decreased as the enlarging uterus compresses the inferior vena cava during pregnancy. A subsequent greater cephalad spread of sensory blockade is observed. Gravid uterus plays a crucial role in affecting the spinal anesthesia level. We hypothesized that maternal abdominal circumference can reflect compressive effect of the uterus and investigated the relationship between abdominal circumference and the level of sensory blockade, and incidence of hypotension following spinal anesthesia with hyperbaric bupivacaine in term parturients...

AIM: Maternal position during induction of combined spinal-epidural anesthesia (CSEA) may affect hemodynamics and block characteristics. This study aimed to assess whether the sitting position is more likely to induce hypotension and higher block level than the lateral position in CSEA with hypobaric ropivacaine. METHODS: Ninety American Society of Anesthesiologists physical status I and II parturients undergoing elective cesarean section were randomized into three groups: the sitting, left-lateral, and right-lateral position groups...

BACKGROUND: The introduction of routine prenatal screening using ultrasound has led to a substantial increase in diagnoses of fetal disorders that are amenable to intrauterine treatment. While an ultrasound guided insertion of small bore cannulas can be performed under local anesthesia, insertion of a fetoscope usually requires anesthetic management for the mother and the fetus. Additionally, the fetus' intrauterine position may have to be manipulated in order to enable access. Such manoeuvres depend on relaxation of the mother's abdominal wall...

Most anesthesia providers prefer to do a subarachnoid block (SAB) for cesarean section because of its rapid onset and reliability to provide adequate anesthesia. However an effect of the SAB is that it causes a spinal-induced hypotension (SIH) in up to 85% of the population. There have been multiple studies that assessed fluid administration, vasopressor administration, maternal positioning, or serotonin blockers given prophylactically to attenuate the SIH response. Despite these multiple studies, the method to prevent and treat SIH remains varied from one anesthesia practice to another...
