Filter by:In the last decades cesarean section rates are getting higher in many countries. The rise in those rates encourages obstetricians to improve operative techniques for a better maternal and fetal outcome. Despite its worldwide spread, a general consensus on the most appropriate technique to use has not yet been reached. The most known surgical technique is the MLC . A modified extraperitoneal method of caesarean section :" French Ambulatory Cesarean Section ( FAUCS) was described in the middle of the 90's by "Denis Fauck" and "Jacques Henri Ravina " However, no study comparing these two cesarean techniques was conducted. From where the investigators initiate this study .
The purpose of this study was to investigate the incidence of hypotension after spinal anesthesia in patients undergoing cesarean section as predicted by preoperative carotid artery corrected flow time measured by Doppler ultrasound. Before entering the operation room, Two inspectors perform two measurements of carotid artery corrected blood flow time respectively, and an average of the four measurements is calculated and analyzed. At this time, the patient's posture is supine, and the head is turned about 30 degrees to the left. Corrected blood flow time (FTc) is measured using carotid ultrasound as previously described by Blehar and colleagues. Corrected blood flow time is calculated by Bazett's formular and Wodey's formular by evaluating a single cycle after several successive cycles have reached a stable and acceptable quality level. The occurrence of hypotension is recorded from the spinal anesthetic injection until the fetus is delivered. The definition of hypotension after spinal anesthesia is that the systolic blood pressure drops to 80 mmHg, less than 75% of the baseline value, or even if it does not meet the former criteria, symptoms that are consistent with hypotension (dizziness, dizziness, dyspnea, nausea or vomiting).
BACKGROUND: Spinal anesthesia (SA) induced maternal hypotension is the most frequent and troublesome complication in cesarean section (CS), compromising both maternal and neonatal well-being. Many strategies have been used to prevent its occurrence but no single technique has been confirmed to be completely effective. the investigators hypothesized that ondansetron, a serotonin-receptor-antagonist, could have beneficial effects on maternal hemodynamics during CS under SA. METHODS: In this prospective double-blind placebo-controlled study, one hundred healthy parturients were randomized to receive either 8 mg of intravenous ondansetron (group O) or the same volume of saline (group S), 5 minutes prior to the induction of SA. All women received a coloading volume of 500 ml of saline. Maternal hemodynamics: blood pressure, heart rate and cardiac output (CO) were measured with a non-invasive device based on pulse wave transit time: the esCCO device Nihon Kohden hemodynamic monitor. Ephedrine was administered to treat hypotension (systolic blood pressure less than 80% of baseline).
The aim of this study is to evaluate the effect of immediate oral hydration initiated within 2 hours after uncomplicated Caesarean section
Enhanced Recovery After Surgery (ERAS) protocols have been proven to be very successful in specific patient populations. An example is with ERAS for colorectal surgery. ERAS protocols in this patient population have been shown to reduce overall morbidity and hospital length of stay (LOS). At the University of Alabama at Birmingham (UAB), the institution has had successful implementation of ERAS protocols for several surgical specialties including colorectal, breast, spine, gynecology, and gynecology-oncology. However, the institution currently does not have a protocol in place for the most commonly performed surgical procedure - cesarean delivery. At UAB, the institution performs approximately 1,000 cesarean deliveries per year. The investigators believe that an ERAS protocol will be beneficial for these patients. Currently, there is very little data published on ERAS protocols. Although this patient population is ideal for an ERAS protocol, there are several barriers that have to be overcome. The data published show promising results for ERAS protocols with cesarean delivery. A larger tertiary care center showed earlier discharge with lower re-admission rates with an ERAS pathway. Currently, the investigators have created a multidisciplinary group at UAB to establish an ERAS protocol for patients undergoing cesarean delivery. This group includes anesthesiologists, obstetricians, nursing, neonatology, pharmacy, and informatics. Once the investigators have implemented this protocol, the investigators would like to perform a retrospective analysis to determine if there are any significant changes in our desired outcomes the investigators will study. Our goal is to demonstrate significantly improved outcomes in the investigators' measured endpoints. The investigators believe that this information will be very useful because although there is a national interest in creating ERAS protocols for cesarean deliveries, there currently is very little published on the subject. The investigators would like to publish the investigators' results and protocol as a resource for other institutions to adopt.
Adequate pain control after cesarean delivery is a major concern both for parturient and for obstetric anesthesiologists, and it usually comprises a combination of systemic and regional techniques.The transversus abdominis plane (TAP) block, affecting the nerves supplying the anterior abdominal wall, is a recently introduced, promising regional analgesic technique for a variety of abdominal and pelvic surgeries including cesarean delivery.(2,3) Infiltration of local anesthetic into the surgical wound (either as a single shot or using indwelling catheters) has long been used for postoperative analgesia. Both the TAP block (4-6) and wound infiltration is superior to placebo; however, it is unknown which of them provides better analgesia after cesarean delivery because of a scarcity of randomized clinical trials. Only 2 studies compared the TAP block with wound infiltration after cesarean delivery with conflicting results, and another study compared it with continuous wound infusion and was prematurely terminated. This study aimed to compare bilateral TAP block with single-shot local anesthetic wound infiltration for analgesia after cesarean delivery performed under spinal anesthesia. We hypothesized that the TAP block would decrease postoperative cumulative opioid consumption at 24 hours
The purpose of this study is to determine the ideal dose of spinal morphine for use in Cesarean section. Spinal anesthesia (single injection in the lower back to numb patients from the waist down) is commonly used in Cesarean section to provide numbness and pain relief during the surgery, and adding morphine to the spinal anesthetic provides long lasting pain relief for up to 24 hours after surgery. The ideal dose of spinal morphine, when given with other types of pain medications such as nonsteroidal anti-inflammatories and acetaminophen, has not been determined. In addition, spinal morphine can have side effects such as nausea and itching, so using a lower dose of morphine may decrease these side effects while providing the same amount of postoperative pain relief. Study participants will be divided into two groups. Group 1 will receive the standard dose of spinal morphine (0.1mg) while Group 2 will receive a lower dose of spinal morphine (0.05mg). Both groups will receive the standard dose of spinal bupivacaine (numbing medication) and spinal fentanyl (short acting pain medication). The additional pain medications (IV Toradol and oral acetaminophen) will be given to both groups after surgery. Pain control and morphine side effects will be compared between the two groups in order to determine the best dose of spinal morphine for cesarean section.
Comparison of two types of analgesia after cesarean section All patients will be anesthetized with spinal technique. Ultrasound-guided transversus abdominis plane or quadratus lumborum block to treat postoperative pain. Postoperative pain will be measured with visual-analog scale (VAS). 1, 2, 6 months after surgery each patient will be called to assess neuropathic pain with Neuropathic Pain Symptom Inventory (NPSI).
Thus study evaluates the advantage of infiltration of the surgical wound by local anesthetics in cesarean section on post operative pain relief. In the study group before closing the skin, both sides of the incision (top and bottom) will be infiltrated by 30 ml of 0.25% BUPIVACAINE and ADRENALIN at 1: 200,000 concentration and then closing the skin. In the control group, the skin will be closed without infiltration. Our hypothesis is that subcutaneous infiltration of the surgical wound by BUPIVACAINE + ADRENALIN at the end of cesarean section will reduce the intensity of post operative pain.
Several treatment strategies are emplemented to prevent post delivery hemorage and decreasing maternal morbidity and mortality .
