Adipokines are bioactive substances secreted from adipose tissue and have various functions on appetite, energy, lipid, carbohydrate metabolism, regulation of blood pressure, and inflammation. One of these is asprosin, discovered in 2016, which is secreted from white adipose tissue. It has been shown that the level of asprosin encoded by the Fibrillin 1 gene can vary in metabolic syndrome associated with obesity, diabetes, and insulin resistance . Some adipokines such as leptin, adiponectin, or resistin are found in increasing levels in the blood and placenta as pregnancy progresses. The detection of high concentrations of adipokines in cord blood has shown that they play an important role in fetal development and metabolism, can interfere with placental development, and affect pregnancy outcomes and fetal growth. Adipokines associated with appetite, energy, lipid, and carbohydrate metabolism have been shown to be effective in modulating pain in recent years. High levels of leptin have been shown to be associated with decreased preoperative pain threshold and increased postoperative analgesic consumption. Recent studies have indicated that asprosin also exhibits analgesic effects in neuropathic pain models and may have clinical benefits in alleviating chronic pain associated with diseases and injuries originating from peripheral structures. It is known that one of the most important factors affecting mothers' approach to anesthesia technique in Cesarean section is their fear of intraoperative and postoperative pain. Almost one in five patients experiences severe acute pain after Cesarean section. Pain can be perceived differently by patients, and even with the same anesthesia technique, some patients may experience more severe pain. Patients' perception of pain is influenced by many factors such as pain threshold, mood, hormonal balance, central sensitization, and genetic factors. We hypothesized that the increased preoperative serum asprosin levels might be associated with increased acute labor pain and that asprosin levels might lead to increased analgesic use in the postoperative period. Additionally, we assumed that patients could alter their preoperative pain threshold and report higher pain scores after surgery due to hyperalgesia caused by high asprosin levels. In this study, we aimed to investigate preoperative serum asprosin levels in patients undergoing Cesarean section with and without acute labor pain and to determine whether there is a relationship between preoperative asprosin levels and postoperative analgesic use.
Abstract: Background: The current "gold standard" epidural analgesia involves some undesirable side effects such as motor and sympathetic blockade. Here, the investigators suggest a new approach for inducing prolonged differential pain blockade during labor by selectively targeting local anesthetic chloroprocaine to the pain-related peripheral (nociceptive) fibers. The investigators approach involves nociceptor-selective anesthesia by selective targeting of ionized local anesthetics into nociceptive fibers via activation of nociceptor-specific TRPV1 channels. The authors demonstrated that activation of these channels by specific TRPV1-agonists (capsaicin or the local anesthetic lidocaine), allows entry of a polarized, membrane-impermeable lidocaine derivative (QX-314) specifically into nociceptive neurons, inhibiting their activity and pain blockade, without causing other neural effects. Capsaicin and QX-314 are not suitable for clinical use, as capsaicin causes severe injection pain and QX-314 is neurotoxic. Here, the investigators use lidocaine as the TRPV1 agonist, and use the high pKa chloroprocaine as the ionized local anesthetic instead of the toxic QX-314. Both drugs are in routine clinical use, but have not been described in co-administration before. The investigators preclinical results show that co-administration of chloroprocaine with TRPV1 agonists, leads to prolonged nociceptor-specific analgesia. KKK Hypothesis: The investigators hypothesize that co-administration of epidural lidocaine (to activate TRPV1 channels) and chloroprocaine (as a polarized local anesthetic which can gain preferential access to nociceptors via opened TRPV1 pores) will elicit selective nociceptive-anesthesia. Methodology: This study assess epidural local analgesia in nulliparous labor. There are 2 stages: Stage 1: Prior to direct comparison of lidocaine (Group L), chloroprocaine (Group C), and a lidocaine-chloroprocaine combination (Group L-C), the investigators first determine equipotential doses of epidural chloroprocaine and lidocaine using double-blinded up-down sequential analysis using the well-established minimum local anesthetic concentration (MLAC or ED50) design. ED50 is estimated using Dixon-Massey analysis and Wilcoxon and Litchfield probit regression. Stage 2: The main phase of the study involves a randomized double-blinded comparison between Groups L, C and L-C where all drug concentrations are based on the ED50/MLAC from the Stage 1. The primary endpoint is a composite measure of selective nociceptive analgesia (VAS pain score / modified Bromage motor score). Secondary outcomes are: 1. pain (VAS 0-100), 2. modified Bromage motor score, 3. thermal imaging of feet and hands, 4. sensory assessment to cold sensation using ice, 5. anesthesia requirement from the PCEA pump, 6. maternal blood pressure. 7. ambulation, and pushing ability in labor. Primary endpoint is assessed using repeated measures ANOVA (first 30-min) and mixed models ANOVA until first analgesic request. Implications: Positive findings will be the first evidence in humans of nociceptor-specific local anesthesia; will provide a more effective neuraxial analgesia protocol for labor, and will lead to future studies of systemic nociceptor-specific local anesthesia.
The aim of the study is to develop a device that can eliminate failed neuraxial placements in challenging patients.The study will attempt to improve safety and efficacy of neuraxial anesthesia with high precision real-time needle visualization through automated real-time needle guidance at the bedside with an experimental device (Accuro 3S). Investigators will verify the clinical workflow for utilizing the Accuro 3S during epidural and spinal procedures and validation of needle visualization while using the device as well as anatomical guidance provided by the device during spinal imaging.The underlying bone imaging enhancement algorithms were introduced in the commercially available FDA approved Accuro. The Accuro 3S will be used to establish needle insertion point and trajectory, after which the clinician will use standard of care methods to advance the needle such as the loss of resistance method.
Epidural Analgesia remains the most effective form of pain relief in labour. After initiating epidural analgesia, there are many epidural drug regimens that can be employed to maintain analgesia for the duration of labour using an epidural catheter. Due to recent advances in medical technology, new epidural pumps, which allow both patient controlled epidural analgesia boluses (PCEA, a common standard of care in many hospitals) and programmed intermittent epidural boluses (PIEB, automatic boluses given in addition to the PCEA bolus), are now available. In this randomized double-blind trial, we aim to evaluate the effects of different combinations of PIEB (epidural bolus volume) and PIEB (bolus volume and time interval) on labour patient-controlled epidural analgesia (PCEA) usage. In theory, the more effective the PIEB combination (the ideal drug volume and ideal time interval), the less PCEA boluses (extra epidural drug) will be used as well as less clinician boluses and less lower limb weakness (motor block) as assessed by the Bromage Score.
Labour pain has different locations, intensity, quality and meaning for each woman, and the experience of pain changes throughout the delivery process. This pain is often associated with varying degrees of fetal malposition, particularly occipito-posterior position, which may apply pressure on pain-sensitive structures within the pelvis. Administration of Injections into the sacral area (both posterior iliac spines and 2 cm downward and medial) is used and have been shown to relieve the pain of labor. Controlling pain with simple methods can reduce the desire of mothers to give birth by cesarean section and make them more diligent for normal birth. The benefit we expect from the research; Since sterile water injection is a safe, effective and low-cost method, it is important to understand the effectiveness of its use to reduce labor pain. It also aims to increase the knowledge of gynecologists about this method.
Summary of the Study Childbirth is one of the most significant and complex experiences in any mother's life. According to a study, labour pain ranges from mild to severe and is felt throughout the body, particularly in the lower abdomen, vagina, and around the waist. The mean pain perception of the prurient as assessed by the Visual Analog scale (VAS) was 7.0 with a range of 1.2-10.0. In a study, 50% of parturients rated labour pain as severe (VAS > 7.1). The majority of the respondents 86.4% desired some form of pain relief. Pain relief during labor is a crucial component of the labor process. Non-drug techniques for alleviating labor pain focus on psychological and physical discomfort elements. A study in Panjab was performed to assess the effectiveness of heat therapy on the lower back among women in labor pain during the first stage of labor and found that heat therapy reduces the severity of pain in the first stage of labor. A study performed in India found that intermittent heat and cold therapy successfully shorten the first and second stages of labor's duration and pain. The purpose of the study is to compare the impact of intermittent heat and cold therapy with heat-only therapy on comfort and duration of labor among primigravida women at a Bharatpur hospital in Nepal. A quantitative research approach will be adopted and the research design will be a true experimental pretest posttest design. It will be conducted among 150 low-risk primigravida women aged 20 to 35 years with a gestation of 37-41 weeks of pregnancy admitted to the maternity of Bharatpur Hospital, Chitwan Nepal who are anticipated to deliver spontaneously. The participants will be divided into 50 in each 3 groups. One group will receive intermittent heat and cold therapy, another group will receive heat-only therapy and one group will be the control group. The tool will be a standard tool which are Visual Analog Scale (VAS) and Childbirth Comfort Questionnaire (CCQ). All the ethical clearance will be obtained before collecting data from Sharda University, Nepal Health Research Council, and Bharatpur Hospital. Informed consent will be taken from all the participants and their rights, privacy, confidentiality, and comfort will be maintained. The participants can withdraw from the study at any time without giving any explanation. The data will be organized and entered into Statistical Package of Social Sciences (SPSS) version 16 for analysis. The data will be analyzed according to the objectives of the study by using descriptive and inferential statistics.
This randomized controlled study aims to compare effects of different essential oils in labor pain, anxiety and childbirth comfort. The main questions it aims to answer are: Is it effective using rosa damascena oil during labor? Is it effective using frankincense oil during labor? Which essential oil is more effective during labor Researchers will compare aromatherapy oils groups to see labor pain, anxiety and childbirth comfort levels of pregnant women.
The primary objective of our study is to use a biased coin up-down allocation methodology to estimate the dose of bupivacaine required after the lidocaine test dose to achieve initial effective comfort in 90% of patients (post test-dose ED90) via the epidural (DPE or EPL) technique in women undergoing labor induction or augmentation; we hypothesize that we will be able to determine the post test-dose ED90 of bupivacaine for each technique with adequate precision to inform the optimal doses to study in a subsequent randomized trial comparing the analgesic effects of DPE vs. EPL. We also hypothesize that the post test-dose ED90 of bupivacaine is lower with a DPE technique than with a conventional epidural technique.
Those prospective parturients that express that they may want an epidural labour analgesia for their delivery will be informed about the possibility to choose between a pump driven epidural or midwife administered intermittent boluses.
