Pudendal Nerve Block vs Penile Nerve Block for Analgesia During Pediatric Circumcision

Start date: May 2019
Phase: N/A
Study type: Interventional

Pediatric circumcision has been realized since the beginning of human civilization. In the United States, a 2014 review revealed a 81% prevalence of men 14-59 years old being circumcised. Circumcision surgery is mostly performed on an ambulatory basis. The best analgesia technique for this procedure has yet to be determined. Local, regional, general anaesthesia or even combinations have been described. The Dorsal Penile Nerve Block (DPNB) has been shown to be superior to topical analgesia in neonatal circumcision. A 2008 Cochrane review showed no difference in pain scores between caudal block and DPNB, but described more motor block with caudal block. For this reason, the 2017 Canadian Urological Association guidelines review recommends using DPNB with a ring block as a standard of care for neonatal circumcision with-out general anaesthesia. However, DPNB does not provide reliable coverage of the ventral surface of the penis and frenulum. Pudendal nerve block (PNB) is another regional anaesthesia technique gaining in popularity with the now widespread use of ultrasound guidance. However, it is still unclear if PNB can give better outcomes than DPNB. The ultrasound-guided pudendal nerve block has only been recently described and was not reviewed as an option at the time of the guidelines writing. PNB can be performed using surface landmarks, with nerve stimulation or with ultra-sound-guidance. It has already been proven to have lower surgical complication rates than caudal block for hypospadias surgeries. Regarding DPNB, a variety of techniques have been described using either surface landmarks or ultrasound guidance. In the past ten years, two RCTs in Lebanon and Turkey compared PNB and DPNB for penile surgeries, showing lower pain scores and lower narcotics consumption in the pudendal nerve block group. None of these studies used ultrasound-guidance. The investigators perform more than a hundred pediatric circumcisions yearly for medical indications. The surgery is done under general anaesthesia in association with either PNB or DPNB, depending on the anesthesiologist's preference. The primary objective is to compare analgesia between the two blocks during and after pediatric circumcisions to minimize post-operative pain. The research team will compare peri and postoperative pain in children receiving either ultrasound-guided pudendal nerve block or ultrasound-guided dorsal penile nerve block for circumcision surgery.

SERRATHOR TRIAL : Interest of the Novel Serratus Plane Block in Post Operative Analgesia After Video-Assisted Thoracoscopic Lobectomy

Start date: March 2019
Phase: N/A
Study type: Interventional

Pain after thoracic surgery remains a challenge for anesthetists. Although VATS for lobectomy is associated with fewer complications compared to thoracotomy, pain after VATS needs to be treated with opioids. Opioids may lead to PONV, respiratory depression, sedation and pruritus. As part of multimodal analgesia and opioids sparing, several local regional techniques has been described: paravertebral block, thoracic epidural analgesia, intercostal block. To date, there is no gold standard for regional anesthesia after VATS. Serratus plane block is a local regional technique, recently described for analgesia after breast surgery and ribs fracture. In our hospital center, since 2016, we used the Serratus plane block for patients scheduled for lobectomy VATS : a local retrospective trial showed that SPB was associated with a lower consumption of morphine. The purpose of this randomized controlled double blinded study is to evaluate the analgesic effect of the Serratus plane block, added to a general anesthesia on post operative pain control after VATS lobectomy.

The Use of Lumbar Erector Spinae Plane Block for Hip Arthroplasty at the L4 Interspace

Start date: March 1, 2019
Study type: Observational

Over 300,000 hip arthroplasties are performed each year in the United States.1 This number has been steadily increasing over the last two decades, likely due to increased life expectancy and, more significantly, the obesity epidemic. Traditionally, this procedure has been performed under general anesthesia. However, neuraxial and regional anesthesia have become more commonly utilized to aid in postoperative analgesia. Postoperative pain control has a significant impact on earlier ambulation, initiation of physical therapy, better functional recovery, and overall patient satisfaction.2 Moreover; optimal pain management can reduce the duration of hospitalization and the risk of adverse events, such as deep vein thrombus. The use of regional anesthesia reduces the postoperative opioid requirement, thereby decreasing the degree to which patients suffer the side effects of opioids, namely sedation and constipation, and less frequently nausea, vomiting, respiratory depression, pruritus, and retention. In the past, femoral nerve block, fascia iliaca compartment block, lumbar plexus block and the quadratus lumborum block have been shown efficacious for pain relief for hip arthroplasty. However there are several risk factors such as quadricep weakness and difficulty of the block that causes a limitation in the used of this blocks. Recently, the erector spinae plane block has been introduced as an alternative to the blocks above. This block was first described in the literature in 2016 when it was used to treat chronic neuropathic thoracic pain. Since then, there have been studies demonstrating its efficacy with a thoracic approach for analgesia in breast surgery and rib fractures.9 Only two case reports to date have demonstrated a lumbar approach to achieve analgesia for hip arthroplasty.10,11 The purpose of the study is to determine whether or not a lumbar erector spinae plane block is effective at improving postoperative pain in patients receiving hip arthroplasty.

The Impact of Nerve Cross Section Area on Sensory Block Onset

Start date: April 19, 2019
Phase: N/A
Study type: Interventional

The study aims to describe a correlation between the nerve cross section and the sensory or motor block onset time. Therefore, different nerve cross sections with their Motor and sensory onset times are compared in order to find a correlation. In the case of discovering a correlation, this could be translated into clinical practice, where a more tailored and individualized approach to performing peripheral nerve blocks would be possible, thus lowering the risks of adverse events occurring.

ESP Volunteer LA Spread Controlled by MRI

Start date: February 1, 2019
Phase: N/A
Study type: Interventional

Background and Objectives: The Thoracic Erector Spinae Plane Blockade (ESPB) is a regional anesthesia technique recently described by Forero M in November 2016 , whereby local anesthetic (LA) is injected in the inter Fascial space between posteriorly the fascia of Erector Spinae Muscles (IFS-ESP) (the iliocostalis, longissimus, and spinalis muscles ) and anteriorly the inter-transverse ligament to achieve multi-metameric analgesia for thoracic or upper abdominal surgery. Recent studies published showed controversies on the spread of the local anesthetic and also the clinical efficiency . The clarification of mechanism of the paravertebral block is one example for the effectiveness of Magnetic Resonance imaging (MRI) in this context We therefore designed a prospective study in volunteers to examine the spread of LA via MRI investigation in correlation with the extent of somatic block after a standardized ultrasound (US) guided ESPB. Our study will study the spread at T4 or T5 level which is the level used for most of thoracic, cardiac and breast surgeries to determine if dye would spread anteriorly to the involve or igins of the ventral and dorsal branches of the spinal nerves. Methods: After ethical committee approval we will select 10 Healthy volunteers to perform Unilateral ESP single shot block with a very low dose of Local anesthetic (LA) (Ropivacaine 0.5% 1 mg/kg (Maximal dose recommended = 3 mg/kg ) mixed with 0,1ml gadolinium After injection an ultrasound image of the spread of the LA with an easy 3 Dimension will be acquired. 10 and 30 minutes after injection a MRI will be performed to analyze the ultrasound spread. An Evaluation of the extension of Sensory Blockade. Patient will be kept under monitoring for 1,5 hours to assess any complication Sensory block will be assessed. At 1 week after the study day, all volunteers will undergo an investigation of the puncture sites to exclude puncture- related infection or hematoma. Statistical analysis will be done The cranio-caudal spread of LA will be recorded (US + MRI) and described for each of the volunteers.

NCT ID: NCT03679897 Completed - Regional Anesthesia Clinical Trials

Comparison of 0.375% Ropivacaine and 0.25% Levobupivacaine for Infraclavicular Brachial Plexus Block

Start date: September 18, 2018
Phase: Phase 4
Study type: Interventional

Infraclavicular brachial plexus block has been used more frequently with the development of high-resolution ultrasound. Compared with peripheral nerve block using landmark technique or nerve stimulator technique, ultrasound-guided peripheral nerve block decreases the required dose of local anesthetics. As the dose of the drug used decreases, the systemic toxic effects of local anesthetics are reduced. However, the decreased dose of the drugs might have influence on the onset time of local anesthetics. Thus, the investigator aimed to evaluated the onset time of the two equipotent local anesthetics, 0.375% ropivacaine and 0.25% levobupivacaine.
