NCT ID: NCT04565093 Completed - Clinical trials for Arthroplasty Complications

Efficacy of iPACK After Unilateral TKA

Start date: September 28, 2020
Phase: N/A
Study type: Interventional

Total knee arthroplasty (TKA) is a common orthopedic procedure associated with severe postoperative pain which may limit patient rehabilitation and hospital discharge. Although various analgesic techniques have been proposed, there is currently no consensus on the optimal protocol to improve functional outcomes following TKA. The ideal analgesic regimen post TKA should enable adequate pain control, early mobilization and physical therapy, shorten hospital stay, reduce the risk of postoperative complications and improve patient satisfaction. Our hypothesis is iPACK (Interspace between the Popliteal Artery and the Capsule of the posterior Knee) peripheral nerves anesthetic block is superior to Periarticular local Infiltration Analgesia (LIA)which is commonly given by the surgeons during the TKA in terms of pain relief and early mobilization.

NCT ID: NCT04403724 Completed - Clinical trials for Cesarean Section Complications

Sequential and Mixture Injection of Opioids and Hyperbaric Bupivacaine

Start date: July 11, 2020
Phase: Phase 4
Study type: Interventional

Neuraxial anesthesia, especially the subarachnoid block, is the preferred method for LSCS. The intrathecal spread of local anesthetic drugs is unpredictable. However, Baricity, which is the relative density of local anesthetics to that of CSF, is a key determinant of the local anesthetic spread within the subarachnoid space. Alterations in the baricity of a solution to the extent of 0.0006 g/ml-1 can alter the spread of local anesthetic solution in CSF. Patients features such as position, weight, height, and age, and local anaesthetic characteristics such as density, PH, and temperature may play a role as well. Bupivacaine is the main local anaesthetic used frequently for the subarachnoid block. Hyperbaric bupivacaine has dextrose added at a concentration of 80 g/ml to increase its density to 1.0262 which is higher than that of cerebrospinal fluid (CSF), leading to a more predictable spread after intrathecal injection. Opioids such as morphine and fentanyl are commonly injected as adjuvants to hyperbaric bupivacaine. Their synergistic role leads to satisfactory block at smaller subtherapeutic doses of bupivacaine which minimizes the associated side effects. The combination of fentanyl which is lipophilic opioid and morphine which is hydrophilic opioid results in rapid onset and prolonged course of perioperative analgesia. In an in vitro study, the mean densities of fentanyl and morphine were found to be 0.9957 and 1.0013 respectively while the mean density of CSF in term pregnant woman is 1.000306. Thus, opioids spread freely within the CSF interacting on the spinal and supraspinal opioid receptors. They have a synergistic effect to bupivacaine leading to adequate sensory blockade with lesser hemodynamic adverse effects. Nevertheless, opioids are commonly mixed with hyperbaric bupivacaine in a single syringe before intrathecal injection. This practice alters the density and PH of the mixture which may impact the pharmacokinetics of each individual drug. Therefore, we hypothesize in this study that separate injection of opioids and hyperbaric bupivacaine may improve their intrathecal spread. This will not only improve the quality of anesthesia, but it will also decrease the associated hemodynamic adverse events and the incidence of undesired high sensory block levels, which all will increase the perioperative patient satisfaction.

NCT ID: NCT04252820 Completed - Clinical trials for Perioperative Complication

Prevention of Perioperative Hypothermia in Transurethral Resection Under Spinal Anaesthesia

Start date: March 1, 2020
Phase: N/A
Study type: Interventional

Perioperative hypothermia is one of the most common anaesthetic complications, increasing the morbidity/mortality of our patients. Active prewarming with hot forced-air devices has demonstrated to be the most effective tool to prevent hypothermia, but its use is only recommended in long-term surgeries and the optimal prewarming duration has not been elucidated. Both spinal anaesthesia associated to the irrigation with liquids at low temperature instilled during transurethral resection (TUR) cause a decrease in the core temperature of the patient. This is a clinical trial comparing different time periods of prewarming in patients submitted to undergo elective transurethral resection. Our aim is to assess the effect of different time-periods of prewarming on preventing perioperative hypothermia during TUR with spinal anaesthesia. Investigators will compare different time periods: 0 minutes (control group), 15 minutes, 30 minutes and 45 minutes. 200 patients are going to be included in this study (50 patients in each group). Measurement of temperature will be performed using a tympanic thermometer and zero-heat-flux temperature sensor. Patients will be followed throughout their hospital admission. Data will be recorded using a validated instrument and will be analysed using the statistics program R Core Team.

NCT ID: NCT04224766 Completed - Clinical trials for Regional Anesthesia Morbidity

Comparison Between Interscalene and Combined Costoclavicular-suprascapular Blocks for Arthroscopic Shoulder Surgery

Start date: April 1, 2020
Phase: N/A
Study type: Interventional

Postoperative analgesia for shoulder surgery is typically achieved by providing an interscalene brachial plexus block. However, a very common side effect of this block is hemi-diaphragmatic paralysis, a state which may not be tolerated in patients with pulmonary conditions such as COPD. Recently, clinicians have explored new ways to provide satisfactory analgesia while minimizing the pulmonary side effects of the interscalene nerve block. One of these solutions might be to offer the patient a suprascapular nerve block combined to a costoclavicular block. Since these blocks are performed lower in the neck or under the clavicle, the phrenic nerve is less likely to be blocked. Thus, fewer respiratory side effects have been reported when using such blocks. This prospective observational study will evaluate the patient response to surgical stimuli and the opioid requirements intraoperatively in patients undergoing shoulder arthroscopies with either a supraclavicular and costoclavicular blocks or an interscalene block. Study Design: Prospective, randomized open label non-inferiority trial. Subject Population: Adults scheduled to undergo elective shoulder arthroscopy Sample Size: 50 patients Study Duration: Starts February 2020 - Ends February 2021 - Interim analysis at 30 patients Study Center: Assuit university hospital

NCT ID: NCT04166188 Completed - Pain Clinical Trials

Lumbar Erector Spinae Plane Block: Cadaveric Study

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

Erector spinae plane block (ESP block) was first described by Forero et al for the treatment of neuropathic chest pain. Total hip arthroplasty is a surgery with a high potential for severe postoperative pain, and greater attention should be paid to postoperative analgesia. There are multiple forms of postoperative analgesia for total hip arthroplasty, such as subarachnoid morphine, femoral nerve block, obturator and lateral femoral cutaneous block, lumbar plexus block, continuous epidural block, and "3 in 1" block, for example. ESP (LESP) block has emerged based on the same principle as the ESP block in the thoracic region. So far, to the best of our knowledge, there are only a few case reports that evidence its use for hip surgery analgesia. This study aimed to study the local anesthetic dispersion and the mechanism of action of the blockade. An experimental, analytical and prospective study will be carried out in which eight fresh adult human cadavers will be selected and injected with 20 ml of 0.01% methylene blue solution at L4 level. The injection will be performed with a Quincke 20G 100-150mm ultrasound-guided needle with a low-frequency curvilinear transducer (4-8 MHz - SonoSite) in the plane between the transverse process of L4 and the spinal erector muscle, bilaterally in each cadaver. by the same operator. After injection of the solution, the cadavers will be submitted to posterior lumbar region dissection by an anatomist and analyzed the dispersion and impregnation of the blue solution.

Intraoperative Pain and Quality of Surgical Block During Shoulder Surgery Assessed by NOL Index

Start date: September 15, 2019
Phase: N/A
Study type: Interventional

Postoperative analgesia for shoulder surgery is typically achieved by providing an interscalene brachial plexus block. However, a very common side effect of this block is hemi-diaphragmatic paralysis, a state which may not be tolerated in patients with pulmonary conditions such as COPD. Recently, clinicians have explored new ways to provide satisfactory analgesia while minimizing the pulmonary side effects of the interscalene nerve block. One of these solutions might be to offer the patient a suprascapular nerve block combined to a posterior cord block. Since these blocks are performed lower in the neck or under the clavicle, the phrenic nerve is less likely to be blocked. Thus, fewer respiratory side effects have been reported when using such blocks. This prospective observational study will evaluate the NOL response to surgical stimuli and the opioid requirements intraoperatively in patients undergoing shoulder arthroscopies with either a supraclavicular and posterior cord blocks or an interscalene block. Study Design: Prospective, randomized open label non-inferiority trial. Subject Population: Adults scheduled to undergo elective shoulder arthroscopy Sample Size: 100 patients Study Duration: Starts February 2019 - Ends February 2021 - Interim analysis at 50 patients Study Center: Maisonneuve-Rosemont Hospital, CEMTL, Montreal, Quebec, Canada

NCT ID: NCT04001387 Not yet recruiting - Clinical trials for Regional Anesthesia Morbidity

Feasibility of Real-time Ultrasound-guided Spinal Anesthesia Using Dynamic Needle Tip Positioning

Start date: October 27, 2019
Phase:
Study type: Observational

Confirming the L4-L5 or L3-L4 vertebrae level with ultrasound in real time for adults who scheduled elective surgery under spinal anesthesia, and introduce the spinal needle into the subarachnoid space. The ultrasound probe continues to track needle tips in real time by sliding/tilting with short axis view. Check that the spinal needle reaches subarachnoid space, and that CSF is released through the needle hub, and administer the drug. In this process, it is recorded by observing the success of the procedure, the time taken for each step, the number of needle position changes, NRS pain score of the subject, satisfaction with anesthesia, and its side effects.

Ultrasound-guided Bilateral Suprazygomatic Maxillary Nerve Block and Bimaxillary Osteotomy

Start date: September 20, 2018
Phase: N/A
Study type: Interventional

Bimaxillary osteotomy is a surgery procedure of the orthognathic surgery field with the aim to correct dental and facial abnormalities, for both functional and aesthetic cases. The incidence of this abnormality is 5-10% of the population, and its etiology is unknown, with genetic, environmental and embryonic factors related. The surgical technique is complex, and requires osteotomy of the maxillary and jaw, which allows toward, forward, impact and rotation of these bones to fix the edges of the face. The anesthetic management of these patients is a challenge because of the difficult airway management and the perioperative pain control. Multimodal approach for pain control is a fact, and the use of local and regional anesthesia is mandatory. The investigators propose bilateral suprazygomatic maxillary nerve block for a proper control of postoperative pain after bimaxillary osteotomy.
