Filter by: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.
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.
Nerve blocks are used for pain and surgery after many operations today. It has been demonstrated by studies that the amount of postoperative bleeding decreases. On the other hand, surgical teams can use additional medications, such as Tranexamic acid, which have been proven by different studies that have reduced bleeding during and after arthroscopic surgery.
This study is to evaluate whether the administration of ultrasound-guided paravertebral block (PVB) after surgery would produce better postoperative pain control and fast postoperative recovery after Robotic cardiac surgery. Half of participants will receive PVB before surgery, while the other half will receive PVB at the end of surgery.
This is a prospective double blinded randomized pilot trial to evaluate the efficacy of phenopalatine ganglion block (SPGB) block to manage shoulder tip pain (STP) after laparoscopic surgery. Patients undergoing laparoscopic surgery will be approached by a member of the research team and those found eligible for participating will be enrolled after signing an informed consent form. Patients will be randomized to have the SPGB block with saline versus active drug which contains 10% lidocaine diluted to 5%. The block will be performed , by an experienced member of the research team, and the patient will then be followed up by the investigator for any adverse events and levels of shoulder pain.
Regional anaesthesia combined with general anaesthesia has become common in the perioperative management of breast cancer surgery patients. Regional techniques have been recognised to provide excellent post-operative analgesia. It enhances multi-modal analgesia regimes while being opioid sparing, reducing incidence of post-operative nausea and vomiting and allowing earlier mobilisation/discharge and improving treatment success. Therefore identifying the correct regional anaesthetic technique for this group of patients is important in providing optimum peri-operative care.
This study aims to better understand the dispersion of local anesthetic on the Erector Spinae Block, a new technique developed for analgesia. It consists on injection of local anesthetic around the posterior muscles of the Spine. In this study, the investigators will make the injection with coloring solution on cadavers and by dissection will note the dispersion of the solution according to injectate volume. The investigators hypothesize more volume allows bigger spread and will allow new indications of this technique in perioperative analgesia and treatment of chronic Pain
Lumbar Quadrant Blockade is a recent analgesic technique consisting of the injection of local anesthetic around the lumbar square muscle. It was initially described as a technique for abdominal wall analgesia, but later studies have increased the range of indications for laparoscopic and lower limb surgeries. There are several techniques described but with differences in the literature at the point of injection and volume of anesthetic. The exact mechanism of visceral analgesia has not yet been determined. The objective of this study is to determine the dispersion of local anesthetic as a variable dependent on the volume of local anesthetic and injection site and elucidate the mechanisms of analgesia.
Video-assisted thoracoscopic surgery (VATS) provides an opportunity to penetrate the thoracic cavity by video through an incision into the chest wall and facilitate surgical operation of lung pathologies.Various regional methods of anesthesia are currently being used to achieve this goal. The aim of the study was to assess the effectiveness of Long thoracic nerve bloc on postoperative VATS analgesia.
The purpose of this study is to determine whether the transcutaneous application of unmodulated high frequency alternating currents could produce a quickly conduction block of peripheral nerve.
