Comparison of Abdominal Plane Blocks in Postoperative Pain Control in Patients Undergoing LSG

Start date: February 25, 2023
Phase: N/A
Study type: Interventional

The goal of this prospective observational study is compare in terms of efficiency and complications transversus abdominis plane (TAP) and Modified thoracoabdominal plane block-perichondrial approach (M-TAPA) blocks in patients undergoing laparoscopic sleeve gastrectomy. The investigators aims to examine whether M-TAPA block provides more effective analgesia than TAP block in upper abdomen surgeries, and whether there is any difference in terms of nausea- vomiting and need for additional analgesics. The participitans will be observed for postoperative 24 hours with numeric rating score (NRS), postoperative nausea-vomiting score (PNVS) and in terms of need for additional analgesic dose.

Magnesium Sulfate in Bariatric Surgery

MgSObs
Start date: April 21, 2023
Phase:
Study type: Observational

Weight loss surgery, also known as bariatric surgery, has been around since the 1950s and since its inception has been shown to successfully achieve significant and sustainable weight loss in a large number of patients who undergo this intervention, as well , if a beneficial impact is observed in the management of metabolic disorders, such as type 2 diabetes mellitus and hyperlipidemia. After bariatric surgery, patients are at risk of narcotic-related side effects.(2) Because of this, pain management strategies must be implemented to reduce the consumption of narcotic medications. Some studies have reported that a multimodal analgesic regimen can reduce the consumption of postoperative narcotics, as well as the therapy requirements to control postoperative nausea and vomiting. It has also been reported that excess body mass is associated with changes in mineral levels in the body, particularly hypomagnesemia , a condition that is also common in hospitalized patients (Hansen & Bruserud 2018), and has a high incidence in the perioperative environment. Magnesium sulfate (MgSO4) has multiple desirable effects in an anesthetic procedure. It is an antagonist of the N-methyl-d-aspartic acid (NMDA) receptor, which is why it produces an analgesic effect related to the prevention of central sensitization caused by peripheral tissue injury. In addition, other relevant clinical effects of MgSO4 have been reported in anesthesiology, such as its effect as a CNS depressant, modulation of the hemodynamic response, reduction of the intraoperative requirements of anesthetics, analgesics, and muscle relaxants. As well as the potentiation of the effect of non-depolarizing muscle relaxants. The role of magnesium in the body and its pharmacological properties continue to be studied and knowledge of its pharmacological, clinical and physiological characteristics has become essential for the anesthesiologist. There are no previous studies that allow establishing an optimal therapeutic scheme considering all the perioperative clinical effects of MgSO4 and that evaluate the role of genetic variability in pain perception and response to treatment in bariatric surgery.

Difference in Occurrence of Rebound Pain in Patients Undergoing Surgery Under Popliteal Block or Ankle Block

CBFR
Start date: February 15, 2023
Phase: N/A
Study type: Interventional

This is a monocentric, comparative prospective randomized controlled trial. Patients will be randomised into 2 groups and will receive either a sciatic popliteal nerve block or an ankle block (single dose locoregional block injection before the surgery) for elective forefoot surgery in addition to general anaesthesia. The study will: - Compare the occurrence of rebound pain and its recovery between a peripheral nerve block of the popliteal sciatic nerve and an ankle block in patients undergoing lower limb (forefoot) bone surgery under general anaesthesia combined with a PNB achieved in preoperative single injection. - To identify the role of the type of nerve fibers anesthetized and the local inflammatory process in rebound pain development. - Assessing the amount of the local sympathetic block induced by the locoregional anesthesia could be used a non-invasive predictive indicator of the occurrence of rebound pain depending on the nerve fibers involved (purely sensitive versus sensitive and motor).

Clinical Response to Magnesium Sulfate as an Adjunct in the Anesthesia

Start date: October 1, 2022
Phase: Phase 4
Study type: Interventional

Magnesium sulfate (MgSO4) has multiple desirable effects in an anesthetic procedure, including modulation of the hemodynamic response to surgical stress, perioperative anesthetic and analgesic effect, potentiation of neuromuscular blockade, and central nervous system depression. MgSO4 is an antagonist of the N-methyl-d-aspartic acid (NMDA) receptor, therefore it produces an analgesic effect related to the prevention of central sensitization caused by peripheral tissue damage. Objective. To evaluate the perioperative clinical response to MgSO4 as an adjunct to anesthesia. Material and method. Randomized, triple-blind clinical trial that will include men and women over 18 years of age, scheduled for surgery under general or regional anesthesia. After accepting and signing the informed consent, all patients will be subjected to the same pre, trans and postoperative protocol and will be assigned to 2 groups according to the intravenous administration of MgSO4 (placebo and MgSO4). A brief preoperative medical history will be taken, a peripheral blood sample will be taken to determine preoperative serum Mg, the clinical effect of MgSO4 on trans and postoperative analgesia (EVAD), hemodynamic stability (blood pressure (BP) and heart rate ( HR)), motor and neuromuscular block time (Bromage and TOF), and recovery time. The presence of adverse reactions to anesthesia (nausea, vomiting, chills, pruritus, urinary retention, arrhythmias, laryngeal or bronchial spasm) and those secondary to the administration of Mg, SO4, as well as the total doses of all drugs used during the perioperative. The data will be analyzed in the SPSS software.

Comparison of Infraclavicular And Supraclavicular Block

Start date: March 5, 2021
Phase: Phase 4
Study type: Interventional

Ultrasound-guided brachial plexus blocks are used successfully for upper extremity surgeries. In this randomized prospective single-blind study, ASA I-II patients aged 18-65 years undergoing hand, wrist, and forearm surgery will be randomly divided into two groups. First group will receive ultrasound-guided coronal oblique supraclavicular block using a 22G, 50 mm stimulator needle, and the second group, ultrasound-guided lateral sagittal infraclavicular block using a 22G 100 mm stimulator needle. We will prepare, 30 ml of 1:1 0.5% bupivacaine and 2% prilocaine with 5 mcg adrenaline per milliliter as local anesthetic mixture. Block application time, block success, sensory and motor block levels, and postoperative analgesia time will be recorded and compared between the groups. Accordingly, the success rate of the two methods will be evaluated.

NCT ID: NCT04768764 Not yet recruiting - Pain, Postoperative Clinical Trials

Comparison Of Femoral Block And Middle Adductor Canal Block In Patients With Knee Arthroplasty

Start date: April 16, 2021
Phase: Phase 4
Study type: Interventional

Femoral and adductor nerve blocks with ultrasonography(USG) guidance are used effectively and efficiently in post-operative pain management in lower extremity surgical procedures. However, the superiority of these two blocks to each other is still controversial. In this prospective, randomized, double-blind study, patients who underwent elective unilateral knee arthroplasty under spinal anesthesia, will be performed postoperative femoral block or middle adductor canal block with the guidance of USG.Patients who underwent spinal anesthesia and needed sedoanalgesia and who had to switch to general anesthesia will be excluded from the study. The patients will be divided into two groups by simple randomization. Since a total of 52 patients should be included in the study as a result of the power analysis (G-power 3.1); It is planned to take approximately 26 patients for each group.The anesthesiologist, who follows the pain control and mobilization after the block, will not know which study group the patient is in. The blocks will be performed behind the cover while the patient is under spinal anesthesia (Thus, the point of application of the block will not be noticed). In this way, the patient and the anesthesiologist who follows the parameters after the block will be blind to patient's arm. In the first group, 0.25% 20 ml of local anesthetic and middle adductor canal block, in the second group 0.25% 20 ml of local anesthetic and femoral nerve block will be applied We will compare these two blocks in terms of early mobilization, postoperative pain control, motor, and sensory block.

Heart Rate Variability and Electroencephalography Analysis in Laparoscopic Surgery With or Without Transversus Abdominis Plane Block

Start date: August 30, 2020
Phase:
Study type: Observational

Heart rate variability(HRV) and electroencephalography(EEG) has been used widely in anesthetic practice nowadays. One of the most dominant applications is the nociception-analgesia balance. Some evidence support that heart rate variability correlates with perioperative stimulation and postoperative pain score. There are some new evidence support EEG correlated with anesthesia depth and analgesic balance. However, the heterogeneity between the studies and interference factors has limited their usage in clinical practice. On the other hand, peripheral nerve block is broadly used as a routine technique with general anesthesia, but few studies discuss the effect on heart rate variability. Our study focuses on the different HRV and EEG patterns of incision and insufflation during laparoscopic surgery with general anesthesia. Furthermore, we measure the effect of transversus abdominis plane nerve block to heart rate variability during surgery. By this comparison, we can discuss the influences of somatic stimulation, visceral stimulation, and pneumoperitoneum to heart rate variability, and then improve the accuracy of HRV-based nociception-analgesia monitors.

Diaphragmatic Breathing Exercises in Total Knee Arthroplasty Patients

Start date: May 1, 2020
Phase:
Study type: Observational

Rationale: While total knee replacements (TKA) are one of the most commonly performed surgical procedures in the United States, this procedure can also be very painful. Postoperative mobilization and rehabilitation is vital to a patient's recovery, but inadequate pain control can impede patients' progress. Diaphragmatic breathing is an additional non-pharmacological and non-invasive tool with no adverse effects that could aid in recovery. This will serve as a pilot study for a possible larger controlled trials.

NCT ID: NCT03790566 Recruiting - Pediatrics Clinical Trials

Erector Spinae Plane Block for Peri-operative Pain Management in Pediatric Open Pyeloplasty Cases

ESPPOP
Start date: February 20, 2019
Phase: N/A
Study type: Interventional

Regional anesthesia decreases the need for intravenous analgesia in the peri-operative period. Erector spinae plane (ESP) and transversus abdominus plane (TAP) blocks are two common regional anesthesia techniques shown to be effective in open abdominal surgeries. We aim to compare effectiveness of ESP block with TAP block for peri-operative analgesia in pediatric open pyeloplasty patients with a flank incision.
