Regional Anesthesia Block

The aim of the study is to compare the onset time of the costoclavicular approach of brachial plexus block with that of the lateral-sagittal infraclavicular approach in adults distal upper limb surgeries.

A total of 14-18 healthy volunteers will be included. There will be three different procedure days, separated by at least one week. On each visit, the subjects will receive a QL block, according to the randomization process. Each volunteer will undergo pre-procedure screening on the first visit. The blocks will be performed on the same side, by the same anesthesiologist, with at least one week between each block. An anterior QL block will be administered on one day, a posterior QL block on another, and a lateral QL block on the third. The order will be randomized, and both the subject and the research team member assessing the block will be blinded. To compare the dermatomal sensory block distribution, the investigators will use detailed mapping with pinprick, cold, and heat stimuli. A handheld dynamometric assessment of lower extremity strength. The testing will be performed 60 to 90 minutes after performance of the blocks.

This study is comparing two types of pain relief techniques-TAP block and ESP block-for women having an elective cesarean section. Both techniques involve injecting local anesthetic under ultrasound guidance to numb nerves and reduce pain after surgery. The TAP block mainly relieves pain in the abdominal wall, while the ESP block may reduce both abdominal wall and deeper, organ-related pain. The main goal is to see if there's a difference in pain at rest six hours after surgery. The study will also look at pain at later time points, the amount of opioid medication needed, how quickly women can walk, and when they start breastfeeding. A total of 156 women will be randomly assigned to receive one of the two blocks after standard spinal anesthesia. Pain will be measured using a simple 0-10 scale at 6, 12, and 24 hours, both at rest and during movement. The study follows strict ethical rules, ensures patient privacy, and all results-whether positive or negative-will be shared to help improve pain management after cesarean delivery.

This is a multicenter, prospective, observational study aimed at determining the incidence of neurological and non-neurological complications following locoregional anesthesia procedures. The study will collect data on events such as nerve injury, hematoma, pneumothorax, and local anesthetic systemic toxicity.

This clinical trial aims to evaluate the effectiveness of an ultrasound-guided nerve block technique as the sole anesthetic method for patients undergoing outpatient umbilical hernia surgery. The procedure, called rectus sheath block (RSB), involves injecting local anesthetic near the abdominal muscles to reduce pain during and after surgery. The study will compare two groups of adult patients: one receiving the nerve block with a medication called clonidine added to the anesthetic solution, and the other receiving the same block without clonidine. Clonidine may help improve pain control and reduce the need for additional pain medications. By analyzing pain scores, recovery quality, and potential side effects, the study seeks to determine whether the use of clonidine in this context is safe, cost-effective, and beneficial for patient recovery. Participants will answer questionnaires about their pain and recovery during the first 48 hours after surgery.

Although laparoscopic techniques are considered minimally invasive surgical procedures with lower perioperative pain scores compared to open surgeries, they are still associated with significant levels of pain. This study aims to investigate the analgesic effectiveness of two routinely performed regional analgesic techniques in our clinic-ultrasound-guided classic bilateral TAP block and ultrasound-guided bilateral M-TAPA block-in patients undergoing laparoscopic gyneco-oncologic surgery (LGOS), as well as their effects on intraoperative opioid consumption.
