Liposomal Bupivacaine vs Peripheral Nerve Block

Liposomal bupivacaine has gained interest in recent literature for its potential to be an effective adjunct to other pain control modalities in a multi-modal approach to post-operative pain control. The goal of this investigation is to compare the efficacy of local administration of liposomal bupivacaine versus the efficacy of a peripheral nerve block in terms of post-operative pain scores after elective ankle and hindfoot surgery. The investigators hypothesize that there will not be a significant difference in the pain scores of these two groups in opioid naïve patients.

Preoperative Fluoroscopy Guided Hip Articular Branch Blocks and Analgesic Outcomes Following Hip Arthroscopy

Arthroscopic hip surgeries are increasingly being performed as both diagnostic and therapeutic interventions. These procedures are considerably painful, thus requiring the proper pain management techniques in order to provide patient satisfaction and sufficient pain control. Articular branch blocks have not been evaluated for their use in hip arthroscopy, but have potential advantages of blocking the sensory innervation of the entire hip joint, with minimal impact on motor innervation compared to alternative blocks. This current study aims to evaluate the efficacy of using preoperative fluoroscopic-guided blockade of articular branches of the femoral and obturator nerves for analgesic management of patients undergoing arthroscopy compared to a saline sham block. The utility of pre-operative hip articular branch block (ABB) prior to hip arthroscopy will provide superior pain management postoperatively compared to a saline sham block. We hypothesize that the ABB (Articular Branch Block) will reduce the area under the NRS pain scores by time curve (AUC) and decreased oral opioid milligram equivalent use in the first 24 hours post-operatively.

Postoperative Pain Scores and Opioid Consumption in Video Assisted Thoracic Surgery

Video assisted thoracoscopic surgery (VATS) is a type of minimally invasive thoracic surgery (MITS) procedure used for diagnosis or treatment of chest pathologies (pulmonary, mediastinal, chest wall). Most main procedures traditionally performed by open thoracotomy can be performed with smaller incisions using video support. While being less invasive in comparison to open surgery options, thoracoscopic surgery may damage the intercostal nerve and damages muscles. Also it provokes soft tissue edema at the incision area. Therefore, pain can be more intense than expected after thoracoscopic procedures. Post-operation pain is not just an acute problem; 20% of the patients develop chronic incision pain after a thoracic surgery. particiants hypothesis is that continue ESP block catheter application is non-inferior than epidural catheter application in the first post-operative 48 hours regarding post-operative pain relief. The purpose of this study is to invertigate the effects of TEA and ESPB on post-operative pain in patients undergoing VATS.

Cervical Erector Spinae Block Versus Interscalene Block for Shoulder Surgery

Severe pain after arthroscopic surgery is a common experience for the patients . Different regional anesthetic technique has been applicated for postoperative pain relief . The main goal of regional anesthesia regarding postoperative pain relief is to reduce opioid requirements. The most commonly used approach is Interscalene brachial plexus block (ISB), since it provides effective postoperative analgesia upto 12 hours. Erector spinae plane block (ESPB) has been reported for a variety of indications such as thoracic and abdominal surgery. Recently, a novel description of a T2-3 erector spinae plane (ESP) as an alternative to a BP block for an upper extremity surgical procedure. Following these studies, direct cervical ESP block has been recently performed successfully as both clinical and cadaveric study. The investigators hypothesized that cervical ESP block is as effective as (non-inferior) interscalene brachial plexus block in terms of postoperative analgesia of shoulder surgery. To evaluate the effectiveness of the cervical ESP block, the investigators have designed a randomized study. Primary aim is to evaluate the postoperative opioid consumption. Secondary aim is to evaluate postoperative pain scores by Numeric Rating Scale (0 to 10 point scale).

The Effectiveness of Music on Pain and Anxiety in IUD Insertion

Although intrauterine devices (IUDs) are a highly effective contraceptive method, fear of pain during insertion is one barrier to use. A review of literature reveals little investigation of interventions for anxiety management during the procedure. Furthermore, evidence of non-pharmacological interventions for both anxiety and pain management is limited. Music has been shown to be effective at reducing anxiety and pain in a variety of contexts, however to the investigators' knowledge, its effectiveness for anxiety and pain relief during the IUD insertion procedure has not been formally examined. This study will therefore examine the effectiveness of listening to music on anxiety and pain during IUD insertion.

Ultrasound-guided Block of the Supraclavicular Nerves in Clavicular Fractures

A Clavicular fractures (CF) is uncomfortable for the affected patients because the fragments are often strongly displaced by the muscles attached to them and the bony fragments move painfully with every movement of the shoulder. In emergency departments (ED), so far CF has been tackled with drugs that are taken by mouth or injected into a vein. This type of pain management has many side effects since these painkillers act systemically. The aim of the study is to investigate the effectiveness of pain relief in CF to be operated using regional anaesthesia. For this purpose, the supraclavicular nerves (SCN), which run directly under the skin of the neck, will be located using an ultrasound device (US). Under US-guidance the injection needle approaches the SCN and 2-3 millilitres of local aesthetic (LA) are injected around the nerves. The pain relief may last 12 up to 24 hours, which bridges the time until the operation (OP). In order to compare this procedure, CF-patients will be divided into two groups, of which the control group (20) will be treated with painkillers in the conventional manner and the intervention group (20) will receive the US-guided block of the SCN. With the small amount of LA injected, adverse events (AE) are very rare. Nevertheless, the puncture in the side of the neck may cause bruises at the site of the injection or uncomfortable, spreading pain. Systemic side effects are unlikely. In the intervention group, the investigators expect a nearly complete pain relief up to the operation than with conventional pain therapy and a lower rate of side effects than with systemic administration of painkillers.

Observational Peripheral IV Insertion Study

IV placement is a common and necessary for surgical procedures. Unfortunately, pain associated with needle catheterization experienced during peripheral IV placement is a source anxiety and discomfort in many patients. The intensity of pain and distress caused by procedures can vary from mild to moderate, but also may be severe in certain patients resulting in numerous physiological, psychological, and emotional consequences. As such, we ultimately aim to evaluate the techniques that could make the placement of the IV more comfortable.

Pain Scores and Complications do Not Differ at Three Recovery Position After Liver Biopsy

Liver biopsy is still used as the gold standard in the diagnosis of many liver diseases. During the observation after liver biopsy, patients are hospitalized on their right side, which is the biopsy side, with the thought that adverse events (complications) such as bleeding or bile leakage will be less. Patients who do not develop complications after 4-6 hours of observation are discharged home. Some of the patients state that the right side-lying position for 4-6 hours is uncomfortable than the biopsy itself, and they prefer to lie on their back. In our study, researchers aim to investigate the rate of complications after biopsy, what recovery position found more acceptable by the patients.

The Effect of Palmitylethanolamide on Central and Peripheral Sensitization After Heat-induced Hyperalgesia

This planned study is based on a randomized, placebo-controlled cross-over design. Palmityhlethanolamide (PEA) is an endogenous fatty acid amide from the group of N-Acetylethanolamides, which analgesic, anti-inflammatory and neuroprotective effects can be attributed to this. In clinical studies, PEA has mainly been used as an adjuvant in pain therapy. The previous data show clinical efficacy without conclusions that can be drawn about the underlying mechanisms - these have not yet been investigated in a human experiment. The planned study, which demonstrates the mode of action of PEA using an established pain model on healthy volunteers, will help to assign the efficacy to peripheral or central nervous systems. These mechanisms allow to establish mechanism-oriented therapy approaches. These findings are essential for a better understanding of the clinical efficacy and to evaluate the correct fields of application.

PVB vs Ketamine/Lidocaine in Rib Fracture Patients

Rib fractures are a common admission to the trauma service. The mainstay of treatment is pain control to improve respiratory effort in order to offset the risk of pneumonia and mechanical ventilation. In addition to standard pain control modalities, the investigator's institution utilizes paravertebral blocks as well as lidocaine and ketamine infusions for pain control. The current standard of care for pain control is to begin with acetaminophen, ibuprofen or celecoxib and opioids with the addition of paravertebral blocks as needed. In certain situations, a paravertebral block is contraindicated, and pain control is relegated to lidocaine and ketamine infusion. The use of lidocaine infusion alone and ketamine infusion alone for pain control has been studied and has been shown to be safe. However, concurrent use of these two medications to control rib fracture pain is relatively new and the efficacy compared to paravertebral block is not known. The goal of the study is to show non-inferiority of simultaneous lidocaine and ketamine infusions versus paravertebral blocks.

The Effects of Objective Estimation of Pain Response

There are different types of pain generators that give different pain symptoms. In anesthesia and surgery, the pain generator in connection with, for example, surgical procedures is referred to as nociceptive pain. However, there is not enough evidence to support that these physiological changes are direct signs of nociceptive stimulation. The same changes can be seen with an autonomous stress trigger of origin other than just nociceptive stimulation. This means that healthcare professionals who provide anesthesia to patients during, for example, surgery may provide unnecessary pain relief drugs or do not provide pain relief when needed. This is also true in awake patients when pain is complex that, for example, concerns may increase the experience of pain and that healthcare professionals may even then misinterpret and provide more pain-relieving drugs despite the actual need for another drug or complementary treatment. Examples of these include heart rate variation, specific patterns in blood pressure and heart rate response, heart rate amplitude, heart rate range, skin sweating and pupil response. The reason why these changes have not been used to interpret nociceptive stimulation is directly linked to an absence of technology that makes it possible to collect data and interpret these changes. list a number of methods / techniques that are under development, one of which is the Nociception Level Index (NoL). NoL is an indexed value between 0 and 100 and is based on a non-linear combination of nociception-related physiological variables (including heart rate variation, plethysmograph pulse wave amplitude (PPGA) and changes in skin resistance). Possibly NoL is the first evidence-based clinical technology that can discriminate pain response when physiological response is not measured. The research field in the area of non-invasive objective monitoring of pain response in relation to patients' experience of pain is currently almost non-existent in anesthesia / anesthesia care This in turn can also lead to the development of patient safety both during anesthesia and after surgery at nursing department for example, patient-controlled and epidural pain relief in postoperative pain care. investigators intend to study the variation of the NoL index linked to the need for opioids during anesthesia and also after completed anesthesia when the patient wakes up and is in the ward.

Changes in Affective Pain Processing in Human Volunteers

The experience of pain is more than the conscious perception of nociceptive signals. Emotional and motivational aspects accompany pain, leading to its aversiveness and motivation for avoidance. In chronic pain, a negative hedonic shift has been proposed that is characterized by disproportionally increased emotional-motivational compared to sensory-discriminative pain responses. Such a negative hedonic shift is, for example, mirrored in very high comorbidity rates of chronic pain and affective disorders such as depression and anxiety. The aim of this study is to develop methods that allow the differentiation of sensory-discriminative and emotional-motivational pain response and to characterize mechanisms of the negative hedonic shift.
