Filter by:In case of cesarean section (CS) delivery, spinal anesthesia is the best anesthetic choice. It is simple to perform with rapid onset of anesthesia and lower incidence of failed block. Spinal anesthesia avoids the risk of aspiration, the neonatal depressant effect that may occur with general anesthesia (GA), and provides postoperative analgesia, however, spinal anesthesia has a lesser control on the level of blockade, may give insufficient visceral pain block and may be associated with nausea and vomiting especially during peritoneal traction, closure and uterine manipulation, exteriorization and rotation. A previous study reported nausea and vomiting in up to 70.5% patients in the spinal group while the incidence of moderate to severe pain was more frequent in exteriorized uterus patients. Increasing the dosage of intrathecal local anesthetic may contribute to a decrease in the occurrence of intraoperative visceral pain, but at the cost of the risk and adverse effects of greater blockade.A variety of adjuvants have been used to prevent these disadvantages. The commonly used adjuvants include opioids; α2 stimulants such as clonidine and dexmedetomidine; NMDA receptor antagonist such as ketamine; GABA receptor agonists such as midazolam. The added intrathecal opioids as fentanyl and nalbuphine to local anesthetics give a sufficient intraoperative visceral analgesia when they were used in C.S., with less sympathetic block and hemodynamic effect, and reduces the need for intraoperative analgesics with prolongation of postoperative analgesia. Nalbuphine, a mixed agonist-antagonist opioid, has a potential to attenuate the mu-opioid effects and to enhance the kappa-opioid effects. It was synthesized attempting to produce analgesia without the undesirable side effects of mu agonist. Also, its combination with mu agonist opioids was tried by many researchers to decrease the incidence and severity of the common mu agonist side effects (respiratory depression, undesirable sedation, pruritus, bradycardia, nausea, vomiting and urinary retention), plus it can antagonize spinal induced shivering. Meanwhile, the benefits of both kappa and mu analgesia can be obtained. Few studies compared the effects of intrathecal nalbuphine (opioid agonist-antagonist) and fentanyl (opioid agonist) as adjuvants to bupivacaine in spinal blocked for CS with variable results. However, they didn't compare their ability to control the visceral pain aggravated by uterine exteriorization in cesarean section under spinal anesthesia. This study will try to answer the question is nalbuphine effective enough in such scenario to be used routinely as a safer alternative to fentanyl, which is the opioid in common practice added to bupivacaine? Aim of the study: To compare the ability of the used doses in the study of intrathecal nalbuphine and intrathecal fentanyl to control the visceral pain aggravated by uterine exteriorization in cesarean section under spinal anesthesia Objectives: - To evaluate the visual analog scale (VAS) for visceral abdominal and shoulder pain every 5 minutes and the maximum score will be recorded for 30 minutes from the time of baby delivery. - To calculate the total fentanyl used for VAS ⩾ 4
A Clavicular fractures (CF) is uncomfortable for the affected patients because the fragments are often strongly displaced by the muscles attached to them and the bony fragments move painfully with every movement of the shoulder. In emergency departments (ED), so far CF has been tackled with drugs that are taken by mouth or injected into a vein. This type of pain management has many side effects since these painkillers act systemically. The aim of the study is to investigate the effectiveness of pain relief in CF to be operated using regional anaesthesia. For this purpose, the supraclavicular nerves (SCN), which run directly under the skin of the neck, will be located using an ultrasound device (US). Under US-guidance the injection needle approaches the SCN and 2-3 millilitres of local aesthetic (LA) are injected around the nerves. The pain relief may last 12 up to 24 hours, which bridges the time until the operation (OP). In order to compare this procedure, CF-patients will be divided into two groups, of which the control group (21) will be treated with painkillers in the conventional manner and the intervention group (21) will receive the US-guided block of the SCN. With the small amount of LA injected, adverse events (AE) are very rare. Nevertheless, the puncture in the side of the neck may cause bruises at the site of the injection or uncomfortable, spreading pain. Systemic side effects are unlikely. In the intervention group, the investigators expect a nearly complete pain relief up to the operation than with conventional pain therapy and a lower rate of side effects than with systemic administration of painkillers.
Background: Both health professionals and consumers use menthol-based topical analgesics extensively for the temporary relief of pain from musculoskeletal ailments or injury. However, there are no reports of differences in the pain pressure threshold (PPT) or the relative effectiveness of topical analgesics to reduce pain in the upper and lower body muscles and tendons. Objectives: The objective of this study was to investigate whether differences existed in PPT and relative pain attenuation associated with a menthol based topical analgesic over a variety of upper and lower body muscles and tendons. Design: Randomized allocation, controlled, intervention study. Method: Sixteen participants (10 females and 6 males), who were tested on their dominant or non-dominant side. The order of specific muscle / tendon testing was also randomized, which included upper body (middle deltoid, biceps brachii, and lateral epicondylar tendon) and lower body locations (quadriceps, hamstrings, gastrocnemius, lumbo-sacral erector spinae muscles, and patellar and Achilles tendons). PPT was monitored before and 15-minutes following the application of a menthol based topical analgesic.
This is a double-blind, randomized, placebo-controlled, multicenter study of the efficacy and safety of tolperisone (a non-opioid) or placebo administered in subjects with pain due to acute back muscle spasm.
This planned study is based on a randomized, placebo-controlled cross-over design. Palmityhlethanolamide (PEA) is an endogenous fatty acid amide from the group of N-Acetylethanolamides, which analgesic, anti-inflammatory and neuroprotective effects can be attributed to this. In clinical studies, PEA has mainly been used as an adjuvant in pain therapy. The previous data show clinical efficacy without conclusions that can be drawn about the underlying mechanisms - these have not yet been investigated in a human experiment. The planned study, which demonstrates the mode of action of PEA using an established pain model on healthy volunteers, will help to assign the efficacy to peripheral or central nervous systems. These mechanisms allow to establish mechanism-oriented therapy approaches. These findings are essential for a better understanding of the clinical efficacy and to evaluate the correct fields of application.
In this study the intervention consists of a one-day-training program for nurses and three supervised ultrasound guided femoral nerve block (UGFNB) per registered nurse. The training consists of an instruction movie, one-day on-site-simulation and practical examination. The nurses are watching an instruction video and review current local guidelines for UGFNB in advance. The one-day training is situated in a simulation center and consists of theoretical and practical training divided into; infection prevention, anatomy, use of ultrasound and prevention and treatment of complications. A ultrasound model (Gen II Femoral Vascular Access and Regional Anesthesia Ultrasound Training Model) and a living human model is used to examine the femoral nerve and the neighboring structures using ultrasound. At the end of the one-day course, the nurses attends a practical examination with the researchers and anesthesiologists observing, to assure that they could perform the UGFNB procedure correctly. To pass the exam and be able to move on to the supervised blocks in real patients, there has to be a consensus between the researchers and anesthesiologist that they had sufficient knowledge and practical skills. 1) Sterile procedure 2) Management of the ultrasound machine and oral description of the anatomic surroundings in the groin area 3) Preparation of the local anesthetics and performance of an UGFNB. They also have to do an oral presentation in how they would perform a cardiopulmonary resuscitation procedure and how to manage complications / toxic reactions. Approved exam required at least seven points. This study will explore if a one-day course as described above is adequate, sufficient and maintains the safety framework of performing UGFNB in nurses
This study aims to evaluate the analgesic efficacy of single dose of a new paracetamol formulation (paracetamol UNIFLASH) for buccal use in comparison to two different doses of an oral paracetamol form controlled versus placebo.
Negative pressure wound therapy (NPWT) has been shown to improve wound care outcomes for acute and chronic wounds as well as for surgical incision sites. We have found that patients report significant pain during dressing changes specifically with the removal of the clear adhesive drape. Upon review of the literature, there were multiple studies related to pain and the removal of the sponge (filler) but limited studies relating to the pain associated with the removal of the drape. The patient reported pain with drape removal has led to increased psychological stress and decreased compliance with the dressing change protocol. Application of a topical anesthetic to the drape during the dressing change has the potential to decrease the pain experienced by the patient. An FDA approved ethyl chloride spray is a topical anesthetic that can be sprayed onto the outer perimeter of the drape during the dressing change as a means to decrease pain. We hypothesize that the use of ethyl chloride spray will result in patients experiencing less pain leading to decreased psychological stress, improved compliance with dressing changes, and overall improved customer satisfaction.
In this study the investigators wish to investigate whether halophyte-based cream applied to the skin can reduce itch applied by means of small needles from the plant mucuna pruriens (also called cowhage) or by histamine (an itch-evoking substance formed in the human body). Further, the investigators wishes to investigate whether long-term application of halophyte-based cream has a pain-relieving effect on heat/cold and pinprick stimulations.
Acute non-specific low back pain (LBP) is one of the most common complaints at the emergency department. It is more prevalent in countries with high-income economies, where 60-80% of the population report back pain at some point in their life. Numerous medication options are available for acute LBP relief such as non-steroid anti-inflammatory drugs (NSAIDs), myorelaxant drugs, opioids, and benzodiazepines. Magnesium is a physiological voltage-dependent blocker of N-methyl-D-aspartate NMDA)-coupled channels that can influence inflammatory pain and neuropathic pain through several different mechanisms. In this study the investigators aimed to investigate the effect of magnesium oral supplementation for acute low back pain.
