Filter by:To study the core temperature perioperatively in patients due for elective cesarean sectio in spinal anaesthesia. Core temperature will be registered by a zero-flux (SpotOn. 3m) probe on the forehead, starting in the holding area and continued until normotemperature post-operatively.
The purpose of this prospective single center, randomized study is to determine if ultrasound guided Transversus Abdominis Plane (TAP), Quadratus Lumborum (QL), and Erector Spinae Plane (ESP) blocks decrease opioid consumption in subjects undergoing elective cesarean section.
Approximately 20% women who undergo cesarean delivery would suffer from severe post-operative pain, which may further increase their risks from developing postpartum depression. Predictive factors such as pre-operative pain, age and anxiety could significantly contribute to post-operative nausea and vomiting (PONV) and pain in general surgery, however little information is available with regards to cesarean delivery. The investigators would investigate the risk factors of causing post-operative emesis after cesarean delivery, and to reaffirm that there is a positive correlation between pain on local anesthetic injection, presence of mechanical temporal summation (MTS) and post-Cesarean pain scores.
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
Hypotension is a common complication in pregnant women after spinal anesthesia and related with the dose of local anesthetic. Injecting small dose local anesthetic into subarachnoid space can decrease the incidence of hypotension, but increase the risk of incomplete analgesia and muscle relaxation. The investigators hypothesize there is an optimal dose of bupivacaine and ropivacaine for subarachnoid injection in pregnant women, which can cause enough anesthesia and obviously decrease the incidence of hypotension without prophylactical prehydration and vasopressors. To verify this hypothesis, full-term pregnant women who were scheduled for elective cesarean section were recruited.Combined spinal-epidural anesthesia was performed for pregnant women after written informed consents. The dose of bupivacaine or ropivacaine is small and depends on height of pregnant women. The blood pressure, heart rate, respiratory rate, SpO2 and fetal heart rate were recorded and the blood flow volume of uterine artery was monitored The sensory and motor block were evaluated. After delivery, umbilical blood samples were taken for blood gas analysis. APGAR scores and neurological behavior of infant were evaluated and recorded. In the intraoperative period, side-effects and requirement for sedation, epidural injection or general anesthesia were noted. The quality of anaesthesia (judged by the anaesthetist), the quality of muscle relaxation (judged by the surgeon) and the degree of intraoperative comfort (judged by the patient) were recorded as excellent, good, fair or poor.
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.
