Filter by:The lungs of the fetus are filled with fluid and it is essential that fetal lung fluid is cleared at birth. This process is mediated through the activation of airway epithelial sodium channels (ENaC). In animals, ENaC is considered crucial for postnatal pulmonary adaptation. In humans, postnatal ENaC expression is dependent on gestational age and its activity, measured as nasal potential difference, correlates with lung compliance. Therefore, in the human newborn infant ENaC may be important for physiologic postnatal adaptation. The activity of ENaC is increased by beta-agonists, such as salbutamol. We hypothesize that low pulmonary expression or activity of ENaC in the perinatal period causes delayed clearance of lung fluid and thereby contributes to the risk for development of transient tachypnea of the newborn (TTN) in term infants born by Caesarean section (CS).
Currently there are no published studies comparing the efficacy of Chloraprep and povidone-iodine in decreasing postoperative- wound infection in cesarean sections. However, there have been studies involving other types of surgery that have compared the efficacy of different types of preoperative cleansing agents in preventing postoperative wound infection. These studies have shown that controversy exists over which antiseptic skin preparation is the most effective for preventing postoperative surgical wound infections. The standard of care at Los Angeles County Hospital for preoperative skin antiseptic in cesarean sections is povidone- iodine 10% (betadine), however many other hospitals have made the transition to using Chloraprep. In an attempt to improve on the current standard of care, we propose a quality improvement prospective randomized study to compare the difference in postoperative wound complications with the use of povidone- iodine and Chloraprep as a preoperative antiseptic in cesarean sections. We hypothesize that Chloraprep will be better than Betadine at reducing the incidence of positive bacterial cultures following cesarean sections.
Cesarean delivery under general anesthesia is one of few only surgical procedures, where the most important factor of safety is the speed of the surgery, as a newborn adaptation strongly depends on a time between induction to the general anesthesia (and administration of anesthetics) and pennywort ligation. The shortest possible interval is essential for the amount of anesthetics crossing placenta into the fetal circulation. The primary objective: To compare surgical conditions for fetus delivery in Cesarean section under general anesthesia with deep neuromuscular blockade versus standard procedure with succinylcholine. The primary safety objective: To compare influence of different levels of neuromuscular blockade and surgical conditions on newborn adaptation after the Cesarean delivery. The secondary objectives: To compare influence of deep versus no/shallow muscle blockade during the entire Cesarean section on surgical conditions for suture of the uterus and the abdominal wall with attention to blood loss, time of surgery and surgical complications. To describe pharmacodynamics and pharmacokinetics of deep neuromuscular blockade by rocuronium over the course of Cesarean section and its reversal by sugammadex at the end of procedure. Clinical hypotheses: The use of deep muscle blockade in Cesarean section under general anesthesia, including the period of fetus delivery, compare to the standard recommended practice with succinylcholine, will improve the surgical conditions and allow faster and easier delivery of the fetus with positive effect on its postnatal adaptation. Faster delivery will reduce an incision to delivery interval with decrease of time between anesthetics administration and delivery. This will reduce the amount of anesthetics crossing the placenta to the fetal circulation. Both, reduced amount of anesthetics and reduced incision to delivery interval itself will improve a newborn adaptation after Cesarean delivery. Deep neuromuscular blockade will also improve surgical conditions for the whole surgery, when no or shallow only neuromuscular blockade is routinely used. We assume that deep neuromuscular blockade during the entire surgery will create better surgical conditions for faster and easier uterus suture and the rest of surgery and thus reduce perioperative blood loss and incidence of surgical complications.
Hypothesis: The investigators propose that obese parturients will have an increased inflammatory response and a decreased anti-inflammatory response to the surgical and anesthetic insult of caesarean section and that this will be associated with a higher rate of perioperative complications, as compared to non-obese parturients.2 Background: Obese patients exhibit higher levels of inflammatory markers than non-obese patients. Furthermore, obese patients have a higher incidence of perioperative complications, especially wound infections, and this is well documented in the caesarean section population. The pregnant population is unique as a result of the immunologic changes that occur at baseline, and an increase in pro-inflammatory markers is seen in serum and in placental tissue of obese subjects, and has been demonstrated to correlate with adverse fetal outcomes. Specific Objectives: To determine the baseline levels of three established markers of inflammation in term pregnant obese and non-obese patients (defined by a BMI > and < 35 kg/M2 respectively), and examine how they change in response to the stress of surgery/anesthesia. The investigators will correlate the inflammatory response with the incidence of postoperative wound infections. Methods: Patients will be recruited to the study prior to the planned caesarean section. Blood samples for inflammatory marker levels will be performed preoperatively, immediately postoperatively, and at 24 hours postoperatively. Samples will be analyzed for pentraxin-3 (a relatively novel inflammatory marker), C reactive protein (CRP) (a well-known and clinically relevant inflammatory marker), and interleukin-10 (IL-10) (an established anti-inflammatory marker). Plasma will be analyzed by ELISA to determine levels of each biomarker. Patient charts will be reviewed to determine which patients have experienced surgical complications in the 30 days postoperatively. Surgical complications will then be correlated with the measured levels of inflammatory markers. Assuming that the levels of inflammatory cytokines in obese patients will be 15% higher in obese parturients and assuming an alpha error level of 5% and a beta error level of 20%, the investigators would need to study 18 patients per group to prove our hypothesis that inflammatory cytokine levels are correlated with postoperative infections. The investigators plan to study 20 patients per group to account for a potential patient attrition rate of 10% during the study. Significance/Importance: The connection between obesity and dysregulation of the perioperative inflammatory response has not been well established nor has perioperative inflammation in the obese population been linked to the observed increased in perioperative morbidity. The investigators hope to demonstrate these connections and hopefully will be able to identify at risk patients earlier, and in a subsequent study intervene to reduce the risk of postoperative wound infections with pharmacokinetically targeted antimicrobial prophylaxis.
To elucidate the audit's effect on caesarean section rate, and also define the factors influencing the caesarean section rate. From Jan 2007 , pregnant women who delivered in a medical center will be included retrospectively in this study. Our monthly cesarean section audit, focusing on discussing the indications of cesarean section, began from July 2008. Clinical data, indications of cesarean section, and perinatal outcomes were compared between the cases of before and after the audit. Multivariate logistic regression was performed to identify factors affecting cesarean section rate.
Cesarean deliveries are prevalent. Unlike other operations, quick recovery is required for the mother to nurture the newborn child and establishing an appropriate mother-child bonding. Therefore, effective pain management is crucial. In this study we would like to compare between two pain relievers' administration protocols: (1) pain relievers' administration in fix protocol (type of medications, dose and intervals) or (2) pain relievers' administration following demand (the same type and doses, however, medications will be given only following patient's request). The primary outcome will be patient satisfaction, pain control and the necessity of additional medications (rescue doses). The protocols will be used for the first 48 hours following surgery.
The purpose of this study is to determine if epidural meperidine administered by patient-controlled bolus button is equivalent to a low dose infusion plus patient-controlled bolus.
The purpose of this study is to investigate the effect of administering a small dose of glucose on the pregnant women and their neonates during cesarean section. We investigate the safety and efficacy of use of a glucose-containing solution for the pregnant women and the neonates.
The proposed study is a randomized controlled trial with two arms. All patients admitted to Labor and Delivery at Johns Hopkins Hospital for delivery will be approached and offered entry into our study. Once the patient is enrolled, and if she undergoes a cesarean section, the patient will be randomized at time of cesarean section to receive skin closure by either the INSORB™ absorbable staples or subcuticular closure using Biosyn™ suture as is the standard practice. Both an observer scar assessment score (OSAS) and patient scar assessment score (PSAS) will be obtained during this visit. The patient will then be contacted by telephone by a study member 3 months after her surgery for a brief survey (same PSAS survey) assessing her satisfaction with the resulting scar.
Morphine, when given as part of spinal anesthesia, is associated high incidence of nausea and pruritus, which may affect quality of recovery. The investigators hypothesize that long-acting local anesthetic infusions via TAP catheter can provide better quality of recovery after cesarean section than spinal morphine.
