Adductor Canal Block Methods in Bilateral Total Knee Arthroplasty

This study aims to compare the analgesic efficacy of surgeon-performed intraoperative adductor canal block (ACB) and ultrasound-guided anesthesiologist-performed ACB in patients undergoing bilateral total knee arthroplasty (TKA). In a prospective, randomized paired design, each patient will receive surgeon-performed ACB on one knee and anesthesiologist-performed ACB on the contralateral knee. The primary outcome is postoperative pain measured using the Numeric Rating Scale (NRS), and the study is designed to evaluate the non-inferiority of surgeon-performed ACB. Secondary outcomes include opioid consumption, time to first ambulation, length of hospital stay, postoperative complications, and patient-reported outcome measures (PROMs). Additionally, postoperative ultrasound evaluation will be performed to assess the distribution pattern of local anesthetic within the adductor canal, including cross-sectional area and longitudinal spread. This study is expected to provide evidence regarding the clinical effectiveness and technical accuracy of surgeon-performed ACB in comparison with the conventional ultrasound-guided technique.

Comparison of Postoperative Analgesic Effects of Quadro-iliac Plane Block and Transversus Abdominis Plane Blocks in Inguinal Hernia Surgery

Inguinal hernia repair is one of the most commonly performed surgical procedures worldwide. Despite being classified as a minor surgical intervention, moderate to severe postoperative pain is reported in approximately 60% of patients. In a subset of these patients, acute postoperative pain may persist and evolve into chronic post-surgical inguinal pain, significantly affecting quality of life. In recent years, beyond the use of systemic intravenous analgesics, ultrasound-guided fascial plane blocks have been increasingly incorporated into multimodal analgesia protocols with the aim of reducing postoperative opioid consumption and improving pain control. However, the current literature does not provide definitive evidence regarding the superiority of one block technique over another in this surgical population. The primary objective of the present study is to compare the analgesic efficacy of the Quadro-iliac Plane Block (QIPB) and the transversus abdominis plane block (TAPB) in patients undergoing inguinal hernia repair.

Comparison of Conventional and Retroclavicular Approaches for Ultrasound-guided Infraclavicular Brachial Plexus Block

Forearm and hand surgeries are among the most frequently performed surgical interventions both in trauma patients and electively.In these procedures, alternative anesthesia methods such as general anesthesia, regional intravenous anesthesia, regional peripheral nerve blocks and local anesthesia are available. Peripheral nerve blockade can be used for anesthesia and analgesia.This method allows patients to undergo surgery without general anesthesia and increases patient satisfaction by providing effective analgesia in the postoperative period. The aim of this study was to compare the conventional and retroclavicular approaches to infraclavicular block in patients undergoing forearm and hand surgery.

Comparison of Perioperative Characteristics of Regional Anasthesia and General Anesthesia

Shoulder arthroscopy is one of the most common surgical procedures performed today.It is important to perform the surgical procedure under regional anesthesia to prevent intraoperative complications due to general anesthesia.After shoulder surgery, providing adequate analgesia is necessary for both the comfort of the patient and the ability to perform the necessary post-operative rehabilitation exercises early and regularly. Nerve blocks reduces opioid consumption in the postoperative period by providing better pain control and therefore has advantages such as fewer side effects and less risk of pulmonary and cardiac complications. In this study; it was aimed to compare postoperative pain scores, patient satisfaction and surgeon satisfaction in patients who were operated under general anesthesia or who underwent shoulder arthroscopy while awake under regional anesthesia

Comparison of the Postoperative Analgesic Efficacy of SPSIPB and ESPB in Anterior Cervical Discectomy

Anterior cervical discectomy is an operation performed for complaints of pain, numbness or loss of strength due to cervical disc disease. With this operation, pressure due to herniation on the upper neck area, spinal cord or nerve roots is relieved. It is performed by microscopic method from the front of the neck. Nerve blocks reduces opioid consumption in the postoperative period by providing better pain control and therefore has advantages such as fewer side effects and less risk of pulmonary and cardiac complications. In this study; it was aimed to compare the analgesic effectiveness of serratus posterior superior intercostal plane block and erector spinae plane block, with each other and with the control group in the postoperative period in patients who underwent anterior cervical discectomy.

Effectiveness Of Modified-Thoracoabdominal Nerve Block Perichondrial Approach (M-TAPA) In Laparoscopic Cholecystectomy

The Goal of this clinical trial is to determine the advantages of using Peripheral Nerve Block by injecting drugs under the skin on both sides of the abdomen in the upper abdominal area in patients undergoing laparoscopic Cholecystectomy. Study participants will be divided into 2 groups, namely group P1 receiving Modified Thoracoabdominal Perichondrial Approach (M-TAPA) block anesthesia after laparoscopic cholecystectomy and group P2 only receiving intravenous opioids postoperatively. Peripheral nerve blocks on both sides of the upper abdomen are expected to be able to prolong the duration of pain relief, reduce the pain scale, and the total dose of pain medication needed postoperatively. The injection of this peripheral nerve block drug will be carried out by an anesthesiologist. Researchers will continue to anticipate the occurrence of side effects that can occur with strict monitoring and emergency care standards. This study will last up to 24 hours after surgery. The main question it aims to answer is: To prove that the amount of postoperative intravenous opioid consumption with M-TAPA block is lower than the control group.
