Filter by:The purpose of this study is to investigate whether the addition of a medication called epinephrine to spinal medications prolongs the duration of the anesthesia. The medication standardly used in spinal anesthesia is a local anesthetic (bupivacaine) and an opiate pain medication (morphine). These medications typically last about 2 hours. The investigators want to determine if adding epinephrine to the spinal medications prolongs the anesthetic without side effects. A longer duration of anesthesia may be useful in prolonged repeat cesarean section. Epinephrine is known to prolong the action of some local anesthetics, but the investigators want to specifically study combining it with the medications the investigators use regularly for cesarean section. You may qualify to take part in this research study because you are having a repeat cesarean section. Repeat cesarean sections sometimes last longer than 2 hours. The investigators want to determine if epinephrine will prolong the anesthetic.
This study is investigating the relative risks and benefits of using two common materials for coverage of the skin incision at cesarean delivery. We will perform the first prospective and the first randomized controlled trial examining the use of a standard postoperative dressing versus skin glue for coverage of the closed skin incision after cesarean delivery. The hypothesis is that using skin glue for coverage of the incision will be associated with decreased wound complications and increased patient satisfaction.
Comparative study of the surgical outcome of 2-layers closure technique of uterine incision in Cesarean section using bidirectional barbed suture (Stratafix) and conventional suture material (Vicryl) regarding the time of closure and the need of secondary additional suturing or tearing of uterine muscles during suturing.
This study is being conducted to evaluate an FDA approved device called the HEM-AVERT® Perianal Stabilizer and the efficacy in reducing the C-section rate and/or reducing the second stage of labor times.
Currently, spinal anesthesia is most commonly used for cesarean section.But spinal anesthesia can not block the visceral vagus nerve, and the patients are prone to nausea, vomiting, chest tightness or other discomfort when the uterus is stretched .For parturients who have poor uterine contractions and are bleeding larger, obstetricians often use oxytocin to strengthen the contraction of the uterine,which also would increase the parturients' discomfort.Anesthesiologists often intravenous sedative hypnotics (eg.propofol or midazolam) to alleviate the fear of the parturients after the baby is delivered.One of the side effects of propofol or midazolam is that they would lead to the respiratory depression.For the poor respiratory reserve of the parturients, functional residual capacity(FRC) of this group could be reduced by up to 20%, and the oxygen consumption was also increased.The SPO2 could decline quickly intraoperatively.Dexmedetomidine is a novel , highly selective α2 adrenergic receptor agonists , and its selectivity for α2 receptor is 1600 times higher than α1.It also could provide dose-dependent sedation , analgesia , anti-anxiety and inhibition of sympathetic nerves and other effects.Because of its minimal impact on the respiratory , it could safely and effectively used to sedate patients undergoing cesarean section.But the change of endocrine system and hemodynamic of the parturients may affect the pharmacokinetics and pharmacodynamics of some anesthetic drugs.Currently studies have demonstrated the increased sensitivity of some anesthetic drug in parturients, such as lidocaine and isoflurane.The study is aim to explore the optimal dexmedetomidine dose to produce suitable sedation in parturients ,and compared with norman nonpregnant women.
The use of intrathecal opioids for analgesia in the setting of cesarean section has become standard obstetric anesthesia practice. Currently, two opioids are commonly used. These opioids are fentanyl and morphine (Duramorph). Intrathecal opioids are an excellent source of analgesia and act to reduce the stress response to surgery. Currently, most obstetric anesthesiologists use intrathecal morphine for analgesia after cesarean delivery. Morphine provides excellent analgesia for cesarean section. However, use of this medication is associated with side effects such as pruritus and nausea and vomiting. Recently, multiple obstetric anesthesia groups began to use intrathecal hydromorphone for cesarean delivery when morphine was unavailable. As groups began to use hydromorphone, retrospective data became available that demonstrated its safety and efficacy for use during cesarean section. In order to fully elucidate the analgesic and side effect properties of hydromorphone for cesarean delivery, a prospective randomized, double blind study comparing morphine and hydromorphone is necessary. The investigators need to understand whether hydromorphone is as effective as morphine for analgesia after cesarean section, and whether it is associated with fewer or more side effects. The results of the study will allow providers to make educated decisions to better care for their patient.
The objective this trial is to compare immediate and 12 hours postoperative removal of urinary catheter after elective cesarean section; and whether early removal is associated with lower risk of urinary infection compared with delayed catheter removal.
This study is being done to evaluate the scheduled use of intravenous (IV) acetaminophen among cesarean section patients. The study hopes to find out if patients who receive scheduled IV acetaminophen for 48 hours following delivery have lower self-reported pain scores and use less narcotic pain medication than patients who do not receive IV acetaminophen.
One of the problems during general anesthesia (GA) for caesarean section is the place of opioid agents. Indeed, the literature does not provide so far a clear answer regarding the use of opioids prior to extraction of the newborn. Indeed, if the opioid administration at induction is beneficial for the mother (better control of autonomic responses to noxious stimuli), the impact on the newborn can be unfavorable in terms of adaptation to extrauterine life . This is especially true if the birth takes place in a context of prematurity and / or acute fetal distress. The pharmacokinetics of remifentanil make it the only opioid which is consistent with a rapid sequence induction. Its short period of action avoids the manual ventilation of patients before intubation, while providing a peak of action concomitant to the nociceptive stimulation. Patients at high risk of aspiration, including pregnant women, may benefit from this type of morphine at induction. In addition, the fact that remifentanil seems to be associated with relative fetal safety in obstetrical or neonatal context legitimized the development of protocols to study maternal-fetal consequences of the use of remifentanil at induction of AG for emergency caesarean section. While cesarean section under general anesthesia mainly concern premature newborns in France, no work has focused on the use of remifentanil for caesarean section in a context of preterm without preeclampsia. The main hypothesis of this study is to evaluate the safety of the use of remifentanil in terms of adaptation to extrauterine life in children born prematurely by caesarean section under general anesthesia outside the context of preeclampsia. To do this, we will compare two groups of children, one consisting of children born by cesarean section under general anesthesia with maternal remifentanil infusion, the other made up of children born by cesarean section under general anesthesia without maternal infusion of remifentanil. This study is prospective, single-center, randomized, double-blinded. The primary endpoint is formed by the value of the Apgar score less than 7 at 5 minutes, calculated in the delivery room by the team supporting the child (midwives and pediatricians). The secondary endpoints are formed by maternal hemodynamic parameters (SBP, DBP, MAP, HR), the rate of complications during induction (difficult intubation, aspiration), the onset of respiratory distress requiring ventilation mask in the newborn, the rate of intubation in neonates, and the rate of use of adjuvant anesthetic agents.
Both hydromorphone and morphine are administered as part of spinal anesthesia to help improve pain control after cesarean delivery. In this study, the investigators are going to determine the doses of each of those medicines that provides optimal pain control to women undergoing cesarean delivery while limiting side effects related to those medicines. The investigators hypothesize that the doses of hydromorphone and morphine that provide optimal pain control without significant side effects will be 100 micrograms and 150 micrograms, respectively. The investigators further hypothesize that at each respective optimal dose, side effects will be less in the hydromorphone group.
