The Effect of Preoperative Hugging With Family Members on Preoperative Anxiety Levels and Postoperative Pain

The aim of this randomized prospective study is to examine the effect of preoperative family hugging (for at least 20 seconds) on preoperative anxiety levels and postoperative pain. The main question the study aims to answer is: * Does preoperative hugging reduce anxiety levels? * Does preoperative hugging reduce postoperative pain scores? Anxiety and pain scores will be evaluated between patients who hugged and those who did not hug their family members before surgery, and whether hugging has an effect will be assessed.

Effect of GaAlAs 940 Laser on Pain and Wound Healing After Free Gingival Graft

This randomized controlled clinical trial aims to evaluate the biomodulatory effects of a 940-nm GaAlAs diode laser on postoperative pain control and wound healing at the palatal donor site following free gingival graft harvesting. Adult patients undergoing free gingival graft surgery will be randomly allocated to receive either a single session of adjunctive diode laser irradiation immediately after surgery or sham laser irradiation without therapeutic laser energy delivery. Postoperative pain will be assessed using a visual analog scale, while clinical parameters related to wound healing, including bleeding tendency, epithelialization, and wound size reduction, will be evaluated at predefined follow-up time points. The findings of this study may contribute to the clinical understanding of photobiomodulation in free gingival graft surgery.

Effect of iPACK and BiFeS Blocks on Quality of Recovery After Total Knee Arthroplasty

This prospective, randomized, double-blind clinical trial aims to compare the effects of two different posterior knee analgesia techniques-iPACK block (Interspace Between the Popliteal Artery and the Capsule of the posterior Knee) and the Biceps Femoris Short Head (BiFeS) block-when combined with an adductor canal block (ACB) in patients undergoing elective unilateral total knee arthroplasty (TKA). Effective postoperative analgesia is essential for early mobilization, enhanced recovery, and patient satisfaction after TKA. Although ACB provides good anterior knee analgesia while preserving quadriceps strength, additional posterior knee analgesia is often required. The iPACK block is a commonly used technique that targets the posterior knee capsule, whereas the newer BiFeS block aims to provide more selective posterolateral sensory blockade with potentially reduced risk of motor involvement. However, comparative clinical data between these two techniques are limited. The primary objective of this study is to evaluate the difference between the iPACK and BiFeS blocks in terms of Quality of Recovery-15 (QoR-15) scores at 24 hours postoperatively. Secondary objectives include comparisons of postoperative pain scores, opioid consumption, time to first analgesic request, quadriceps and anterior tibialis muscle strength, functional test performance, time to mobilization, active range of motion, and the incidence of adverse events. A total of 74 adult patients scheduled for elective unilateral TKA under spinal anesthesia will be randomized in a 1:1 ratio into two groups: ACB + iPACK block or ACB + BiFeS block. All blocks will be performed under ultrasound guidance by an experienced anesthesiologist. Outcome assessments will be conducted by blinded investigators. The study aims to provide high-quality clinical evidence regarding the effectiveness of the BiFeS block compared to the widely used iPACK technique.

COMPARISON OF THE EFFECTS OF ERECTOR SPINAE PLANE (ESP) BLOCK AND QUADRO İLİAC PLANE (QIP) BLOCK ON POSTOPERATIVE OPIOID CONSUMPTION AND PAIN IN LUMBAR SPINAL SURGERY

Combined Cryotherapy With Compression Versus Cryotherapy Alone After Orthopaedic Surgery

Cryotherapy has been used to enhance recovery after orthopaedic surgery. Many devices are available but few can guarantee a temperature regulation during a prolonged time and therefore have been criticized. The arrival of new advanced cryotherapy devices made it possible to test the effect of prolonged cooling on rehabilitation after arthroscopic orthopaedic procedures.

Pain Education After Rotator Cuff Surgery

Study Title: The Effect of Pain Neuroscience Education Combined with Conventional Rehabilitation on Pain Management and Functional Outcomes in Patients Undergoing Mini-Open Rotator Cuff Repair Purpose: This study aims to investigate whether adding Pain Neuroscience Education (PNE) to a conventional rehabilitation program improves pain management, physical function, and psychosocial outcomes in patients who have undergone mini-open surgery for rotator cuff tears (RCT). The study will also compare the effects of PNE when delivered before versus after surgery. Who Can Participate: Adults aged 40-75 who have been diagnosed with a medium-sized rotator cuff tear and are scheduled for mini-open surgical repair. Participants must meet specific health criteria and be willing to participate in the rehabilitation program. Study Details: Participants will be randomly assigned to one of three groups: Group 1: Conventional rehabilitation only. Group 2: Conventional rehabilitation + PNE before surgery. Group 3: Conventional rehabilitation + PNE after surgery. PNE involves educational sessions that explain the biology of pain, how the nervous system processes pain, and strategies to reduce fear and catastrophizing related to pain. The study will last approximately 12 weeks, with regular assessments of pain levels, physical function, and psychosocial factors (e.g., fear of movement, depression, sleep quality). Potential Benefits: Participants may experience reduced pain, improved shoulder function, and better overall recovery. The study may provide valuable insights into how PNE can enhance rehabilitation outcomes for patients with rotator cuff tears. Potential Risks: Some participants may find the educational sessions time-consuming or mentally challenging. There is a small risk of discomfort during physical assessments or rehabilitation exercises. Why is this study important?: Rotator cuff tears are a common cause of shoulder pain and disability, especially in older adults. Post-surgical pain and fear of movement can slow recovery and reduce quality of life. This study will help determine whether PNE, when combined with conventional rehabilitation, can improve recovery outcomes and provide a better understanding of how timing (before or after surgery) affects its effectiveness.

A Phase 2 Clinical Trial Evaluating the Efficacy and Safety of HSK21542 in Patients for Postoperative Pain Treatment in Orthopedic Surgery

This is a multi-center, randomized, double-blind, placebo/active-controlled study. 160 subjects undergoing orthopedic surgery under general anesthesia are planned to be enrolled and randomized into the HSK21542 group, morphine group, and placebo group.

Minimum Effective Volume of Bupivacaine for Serratus Posterior Superior Intercostal Plane Block in Video-Assisted Thoracoscopic Surgery

This study determined the median effective volume (EV50) of bupivacaine required for the serratus posterior superior intercostal plane (SPSIP) block in patients undergoing video-assisted thoracoscopic surgery (VATS). The SPSIP block is an ultrasound-guided regional anesthesia technique used to provide postoperative pain relief after thoracic surgery. All patients received bupivacaine at a final concentration of 0.25%, prepared by diluting the commercially available 0.5% preparation 1:1 with 0.9% sodium chloride. Using a sequential up-and-down dose-adjustment method, the volume of local anesthetic was increased or decreased according to the block outcome of the preceding patient. The main outcome of the study was the volume that provided an effective block in 50% of patients. EV50 is not a recommended clinical dose; the results are intended to inform future studies targeting higher effective percentiles.

SORE Study: Sitz Baths After Urogynecologic Reconstruction

The purpose of this study is to evaluate the utility of postoperative sitz baths in patient pain perception and recovery following surgical repair of prolapse. The SORE Study is a prospective, randomized controlled trial that aims to compare postoperative pain intensity one week after native tissue repair of pelvic organ prolapse for patients undergoing a sitz bath regimen versus usual care. Findings from this study may contribute to more robust, multimodal postoperative pain management plans if proven efficacious or, alternatively, reduce plastic medical waste and simplify postoperative pain plans if found to be ineffective.

A Clinical Trial Evaluating the Efficacy and Safety of HSK21542 in Patients for Postoperative Pain Treatment in Orthopedic Surgery

This is a multi-center, randomized, double-blind, placebo/active-controlled study. 405 subjects undergoing orthopedic surgery under general anesthesia are planned to be enrolled and randomized into the HSK21542 group, morphine group, and placebo group.

Trans-Auricular Stimulation for Postoperative Inflammation in Spine Surgery

This study is a randomized controlled trial that will evaluate the effect of non-invasive auricular vagal nerve stimulation on inflammatory markers, glycemic control, postoperative pain, and inflammation-related clinical outcomes after long-segment spinal fusion surgeries when compared to current accepted management.

Methadone Pharmacokinetics in Cardiac Surgery

Cardiac surgery frequently leads to significant postoperative pain, with multiple different drug regimens being utilized (both opioid and non-opioid) in an attempt to alleviate this surgical pain. Methadone is currently one of the drugs that is being utilized to help control the pain. It can be given during and/or after surgery. This study hopes to identify the optimal dose of methadone to use to treat this surgical pain.

ESPB vs SPSIP for Postoperative Analgesia After CABG

This prospective, randomized, active-controlled, double-blind, parallel-group study compares the postoperative analgesic efficacy and safety of ultrasound-guided bilateral Erector Spinae Plane Block (ESPB) versus bilateral Serratus Posterior Superior Intercostal Plane Block (SPSIPB) in adult patients (45-85 years, ASA I-III) undergoing elective coronary artery bypass graft surgery. The primary outcome is postoperative pain intensity assessed by Numeric Rating Scale (NRS) at 2, 4, 8, 16, 24, and 48 hours after surgery. Secondary outcomes include intraoperative fentanyl/remifentanil consumption, postoperative morphine consumption, patient-controlled analgesia (PCA) demand/delivery parameters (if PCA is used), need for rescue analgesics, extubation and mobilization times, peak inspiratory flow measured by incentive spirometry at predefined time points, ICU and hospital length of stay, recovery quality (QoR-15 at 0, 24, and 48 hours), mortality, and block-related adverse events.

Effect of Bilateral Ultrasound-Guided TAP Block on Quality of Recovery in Cesarean Delivery Patients Receiving Intrathecal Morphine

This prospective, assessor-blinded observational cohort study will investigate the effect of adding bilateral ultrasound-guided transversus abdominis plane (TAP) block to standard intrathecal morphine (ITM) analgesia on the quality of recovery in women undergoing elective cesarean delivery under spinal anesthesia. All participants will receive ITM as part of routine spinal anesthesia. The TAP group will receive an additional bilateral ultrasound-guided TAP block at the end of surgery, while the control group will not receive any additional block. Both groups will receive standardized postoperative analgesia with intravenous patient-controlled analgesia (IV PCA). The primary outcome is the quality of recovery at 24 hours postoperatively, measured using the validated Obstetric Quality of Recovery-10 (ObsQoR-10) questionnaire. Secondary outcomes include Numerical Rating Scale (NRS) pain scores, time to first breastfeeding, time to mobilization, time to hospital discharge, and total opioid consumption in the first 24 hours after surgery. Outcome assessors will be blinded to group allocation. The study aims to determine whether TAP block enhances functional recovery, reduces pain, and decreases analgesic requirements when used alongside ITM in cesarean delivery patients.

Suzetrigine Versus Usual-care Opioids for Postop Pain in Sports

The goal of this clinical trial is to learn if a Suzetrigine-based multimodal pain regimen can reduce the volume of opioid consumption while maintaining non-inferior pain control compared to an opioid-based multimodal pain regimen after common ambulatory orthopaedic sports procedures. The main questions it aims to answer are: 1. Does including Suzetrigine in the multimodal pain regimen lower the volume of opioids consumed by participants while maintaining non-inferior pain control? 2. How does the side-effect profile of a Suzetrigine-based multimodal postop pain regimen compare to that of an opioid-based multimodal postoperative pain regimen? Eligible participants will be assigned to receive one of the postop pain regimens and report their opioid use, their pain level, and the side effects they faced every day for 7 days.

Postoperative Analgesia in Thoracic Surgery

Analgesic management in thoracic surgery presents a particular challenge for the anesthesiologist, given the intensity of postoperative pain associated with thoracotomy, a surgical procedure that can impact respiratory function and the patient's subsequent recovery. Epidural analgesia is the gold standard. When epidural catheter placement is not feasible, erector spinae plane block is a safe alternative. The ultrasound target is easily visualized, and the injection site is far from the neuraxis, pleura, and major vascular structures. Consequently, this block has been incorporated into standard clinical practice as a treatment option for patients with complex cases or as an alternative approach when epidural catheter placement is not feasible. The primary objective of this study is to assess the effectiveness of postoperative analgesia in patients undergoing elective thoracic surgery. Study Population Design A prospective observational follow-up study will be conducted. ASA I-III patients undergoing scheduled thoracic surgery between November 1 and December 31, 2025, will be included. Their analgesic management will be based on standard clinical practice.

Ultrasound-Guided Transversus Abdominis Plane Block Versus Epidural Block for Umbilical Hernia Analgesia

This observational study aims to compare the postoperative analgesic effectiveness of ultrasound-guided transversus abdominis plane (TAP) block and single-dose epidural anesthesia in patients undergoing umbilical hernia surgery. Pain intensity will be assessed using the Visual Analog Scale (VAS) at predefined postoperative time points. The study seeks to determine which analgesic approach provides superior pain control and patient satisfaction in the postoperative period.

Transversalis Fascia Plane Block Versus Surgical Wound Infiltration for Postoperative Analgesia in Open Inguinal Hernia Repair

The purpose of this clinical trial is to evaluate whether two different analgesic techniques - ultrasound-guided Transversalis Fascia Plane Block (TFPB) and surgical wound infiltration - can improve postoperative pain control in adult patients undergoing open inguinal hernia repair. The key questions that this study aims to answer are: Does TFPB reduce total intravenous opioid consumption within the first 24 postoperative hours compared with wound infiltration? Does TFPB improve postoperative pain scores at rest and during movement compared with wound infiltration? Does TFPB improve patient satisfaction, reduce the need for rescue analgesics, and enhance overall postoperative recovery quality? If there is a comparison group: The investigators will compare the effects of TFPB with wound infiltration to determine whether either technique provides superior postoperative analgesia and reduces opioid requirements. Participants will be asked to: Undergo open inguinal hernia repair under spinal anesthesia. Be randomly assigned to one of two groups: TFPB Group: Receive an ultrasound-guided transversalis fascia plane block with local anesthetic. Wound Infiltration Group: Receive local anesthetic infiltration performed by the surgeon along the incision line. Postoperatively: Report pain scores at defined intervals. Receive standardized IV analgesia with documentation of opioid consumption. Allow assessment of rescue analgesic requirement. Be monitored for adverse events and recovery outcomes.

IPACK vs Adductor Magnus Plane Block Added to Adductor Canal Block for Total Knee Arthroplasty

Total knee arthroplasty (TKA) is among the most frequently performed surgical procedures for degenerative joint diseases, including advanced knee osteoarthritis, rheumatoid arthritis, and post-traumatic arthritis. More than 700,000 TKA procedures are performed annually in the United States alone since 2012, with projections estimating a 143% increase by 2050. A significant proportion of patients experience moderate to severe postoperative pain following the procedure, adversely affecting early mobilization, adherence to rehabilitation programs, and ultimately functional recovery . Femoral nerve block (FNB) was historically the cornerstone of TKA analgesia; however, concerns about quadriceps weakness and associated fall risk led to its replacement by more motor-sparing alternatives . Adductor canal block (ACB) has since become the standard approach, providing analgesia equivalent to FNB while significantly preserving quadriceps strength . Nevertheless, ACB does not adequately cover the posterior capsule and popliteal plexus terminals; consequently, 60-80% of TKA patients report significant posterior knee pain that cannot be sufficiently managed by ACB alone . To address this limitation, several posterior knee analgesia techniques have been described. The IPACK (Interspace between Popliteal Artery and Capsule of the Knee) block targets genicular nerve branches and popliteal plexus terminals by injecting local anesthetic between the popliteal artery and the posterior knee capsule, largely sparing the main motor trunks and providing selective posterior analgesia . The adductor magnus muscle plane (AMM) block is a relatively novel interfascial plane block technique applicable in the supine position simultaneously with ACB. By injecting local anesthetic into the fascial plane along the posterior surface of the adductor magnus muscle, the AMM block aims to spread to the popliteal plexus and posterior capsular branches, potentially mimicking a sciatic nerve block effect . A key advantage of the AMM block is its applicability without patient repositioning during the same session as ACB. The primary objective of this prospective randomized trial was to compare the effects of IPACK and AMM blocks-both added to ACB-on postoperative opioid consumption in patients undergoing TKA. Secondary objectives included evaluating the impact of each technique on postoperative pain scores, mobilization time, functional recovery, and motor function

Comprasion of SPSIP and Rhomboid Intercostal Plan Blocks on VATS

This study aimed to compare rhomboid intercostal plane block and serratus posterior superior intercostal plane block (SPSIPB) to determine the most suitable technique for maintaining postoperative analgesia in video-assisted thoracoscopic surgeries (VATS).

Evaluating the Efficacy and Utility of the Automated Pupillometer in Pain Assessment and Opioid Administration Guidance During the Perioperative Period: A Randomized Controlled Trial

Effective intraoperative and postoperative pain management is critical for patient comfort and recovery, yet traditional methods for assessing pain under general anaesthesia are limited by their subjective nature and reliance on vital signs. Automated pupillometry, which gives the parameters of the pupillary light reflex (PLR) components, offers an objective and quantitative approach to evaluating nociception and pain. This study aims to evaluate the effectiveness of the automated pupillometry in enhancing early postoperative pain control and to assess its utility in guiding opioid administration during the perioperative period. A prospective, non-blinded randomized controlled trial will be conducted with 68 patients undergoing laparotomy for gastrointestinal surgery. Participants will be randomly assigned to either an interventional group, where analgesia is guided by automated pupillometry measurements, or a control group receiving standard pain management. Key outcomes include the time to first rescue analgesia, self-reported pain scores, opioid consumption. The automated pupillometry measurements will be taken at key surgical moments, including before induction, pre-incision, and during recovery. Pain scores and rescue analgesia use will be compared between groups using appropriate statistical tests, and Kaplan-Meier survival curves will analyze time to first rescue analgesia. Regression analyses will explore the relationship between pupillometry readings and postoperative pain. It is anticipated that the automated pupillometry guided group will experience longer intervals before requiring rescue analgesia and report lower pain scores, suggesting improved pain management and reduced opioid use. This study could validate automated pupillometry as an innovative tool for optimizing postoperative pain management, potentially improving patient outcomes by enabling more precise and effective analgesia in surgical settings.

Quadro-Iliac Plane Block Versus Wound Infiltration for Postoperative Pain After Single-Level Lumbar Discectomy

This prospective observational study aims to compare the effects of the Quadro-Iliac Plane Block (QIPB) and wound infiltration (WI) on postoperative acute pain in adult patients undergoing elective single-level lumbar discectomy. QIPB is a newly introduced ultrasound-guided fascial plane block, and it is currently being used in routine clinical practice in our anesthesiology department as part of postoperative analgesia for lumbar spine surgery. Wound infiltration is a conventional method in which local anesthetic is injected into the surgical field at the end of the procedure. In this study, eligible patients will be monitored prospectively without randomization or alteration of standard care. Postoperative pain scores, opioid consumption, nausea and vomiting, patient satisfaction, and recovery parameters will be evaluated during the first 24 hours after surgery. The study aims to provide real-world clinical evidence comparing these two analgesic techniques in lumbar discectomy patients.

Comparison of Intermittent Bolus vs. Continuous Infusion PENG Block for Postoperative Pain in Hip Surgery

This retrospective study evaluates the effects of two different administration methods of the Pericapsular Nerve Group (PENG) Block on postoperative pain control, opioid consumption, and recovery in patients undergoing hip surgery. All patients in the study received: * PENG block via a catheter * Patient-Controlled Analgesia (PCA) with tramadol * Multimodal analgesia, including IV paracetamol and nonsteroidal anti inflammatory drugs (NSAIDs) as rescue analgesia The study compares two groups: 1. Intermittent Bolus Group: A researcher administered 20 mL of 0.25% bupivacaine every 4 hours. 2. Continuous Infusion Group: A pump delivered 5 mL/hour of 0.25% bupivacaine continuously. Both groups received the same total volume of local anesthetic over 24 hours. All PENG blocks were performed under ultrasound guidance at the end of surgery. This study aims to determine whether intermittent bolus or continuous infusion PENG block administration leads to better pain control, lower opioid consumption, and improved recovery outcomes.

Compairing R-ICNB and C-ICNB for Postoperative Pain Management After Minimal-invasive Anatomical Lung Resection

This is a pilot study in which a total of 6 people will participate. This study aims to optimize the postoperative pain management of an anatomically minimally invasive lung resection (RATS) by comparing 2 pain-relieving techniques. As standard, an intercostal block is placed at the end of the procedure by injecting a local anesthetic at the site where the patient will be operated on. This study compares the previous method with the use of cryotherapy as an intercostal block. This technique uses cryo probes and blocks postoperative pain for 1-3 months. By comparing both techniques, it is examined whether cryotherapy requires less pain medication and is therefore more effective.
