Active clinical trials for "Pain, Postoperative"

Acute postoperative pain proper management is important not only for patient satisfaction but also for patient outcome. It may also predispose patients to chronic post-surgical pain .Open nephrectomy is still conducted, although the use of laparoscopic or robotic surgery has increased recently. A flank approach with an eleventh rib partial resection.Several modalities have been implemented for acute postoperative pain control. Intravenous (IV) opioids is one of the earliest and most widely used method, it is insufficient only for managing postoperative pain in some patients with severe pain besides their side effects.ESPB is a relatively simple technique with easily identified sonographic landmarks. Additionally, the ESPB has the potential to provide both somatic and visceral sensory blockade.The aim of this study is to evaluate the effect of ESPB in acute postoperative pain and opioid consumption in patients undergoing open nephrectomy in renal cancer patients.

Video-assisted thoracic surgery (VATS) has become a common procedure in thoracic surgery. Severe postoperative pain may be encountered in patients undergoing VATS. Analgesic methods such as thoracic paravertebral block (TPVB), intercostal block and erector spina plane block (ESPB) are widely used for VATS. Among these methods, ultrasound (US) guided TPVB is the most preferred method. In recent years, the frequency of application of plane blocks as a component of multimodal analgesia has been increased. ESPB and SAPB are some of them. Generally, comparisons are made between ESPB and TPVB in studies and the analgesic effect is evaluated.There are two techniques for SAPB application. In Deep SAPB (DSAPB) application, local anesthetic agent is given under the serratus anterior muscle. In the Superficial SAPB (SSAPB) application, the local anesthetic agent is given above the serratus anterior muscle. Since it is done by entering from the same point in two applications, it is possible to perform these two applications at the same time with a single needle entry. The mechanisms of regional analgesia techniques used after thoracic surgery operations are also different from each other. Therefore, it may be possible to obtain a more effective analgesic effect in patients by combining the mechanism of action of DSAPB and SSAPB , as in the multimodal analgesia method. This study seeks to evaluate the effect of ESPB and combined DSAPB-SSAPB pain after VATS.

This prospective, randomized, double-blind study is designed to evaluate the postoperative analgesic efficacy of dexmedetomidine as an adjunct to ropivacaine in erector spinae block in patients undergoing radical mastectomy. The investigators hypothesis is that the administration of ropivacaine 0.5% associated with dexmedetomidine in the blockade via the plane in the erector spinae is less effective in controlling acute postoperative pain in radical mastectomy than the administration of ropivacaine 0.5% without dexmedetomidine.

This a single-center prospective spread-evaluation study where the primary objective is to assess the spread of local anesthesia in an ESPB using magnetic resonance imaging (MRI). The investigators will include 10 healthy volunteers from the hospitals internal website. All volunteers will receive a one-sided Erector Spinae Plane (ESP) block. 30 min after the block sensitivity to cold and pinprick will be assessed before an MRI is performed after 60 min postblock. An radiology specialist will evaluate the MR images pertaining to the spread of the local anesthesia.

This prospective randomized controlled trial aims to investigate the effect of ultrasound-guided selective supraclavicular nerve block on pain control after Hickman catheter, chemoport, or Perm cath insertion in children.

This study aims to assess analgesia efficacy between liposomal bupivacaine single injection interscalene blockade vs. continuous interscalene nerve block for patients undergoing primary total shoulder arthroplasty.

Acute pain is reported in approximately 80% of patients undergoing postoperative care for various types of surgical procedures in the United States. Another study reported patient postoperative pain intensity with 75% with severe pain in the first 1 to 2 postoperative days and 38% reporting moderate to severe pain at 14 postoperative days. Several modalities have been used as the standard for the management of pain postoperative C-sections. One of the postoperative analgesic modalities for SC is quadratus lumborum block (QLB). This technique has advantages in relieving postoperative pain after C-section because it is considered to be able to relieve visceral pain as well as somatic pain. The transmuscular QLB (QLBT) approach is one of the most frequently used. This technique was found to be effective with regard to the distribution of analgesics to the paravertebral spaces which is the hallmark of QLB. However, this technique was found to be difficult to perform. Difficulties were reported related to the position of the procedure i.e. lateral or sitting position.

Erector spinae plane (ESP) block is an interfacial plane block with visceral and somatic analgesic activity at paraspinal muscles. This study aims to examine the postoperative analgesic efficacy of ESP block after cesarean section (CS) with Pfannenstiel incision under spinal anesthesia.

The goal of this study is to compare the efficacy in controlling postoperative pain of paravertebral block (PVB) with methylene blue visual confirmation and thoracic epidural anesthesia (TEA). This is a single center, parallel-group, prospective study. Patients will be randomly assigned in a 1:1 ratio to receive either PVB or TEA. Primary end-point is pain relief measured with Postoperative Numeric Rating Scale. The secondary end-points are time to perform TEA and PVB, total opioid consumption, postoperative outcomes.

Pain assessment in intensive care patients is a constant challenge. Approximately 50% to 80% of patients report pain at rest or during medical or nursing interventions (for example endotracheal suctioning, mobilization and rehabilitation, presence and care of invasive inputs, etc.). Obstacles to pain assessment and management are most often due to interference with communication due to impaired consciousness, airway support and connection to artificial pulmonary ventilation, or the effect of administered medication. Patients in intensive care are prone to delirium. Delirium can compromise patients' ability to verbalise pain for a variety of reasons (e.g. due to impaired attention, memory, thinking and language barriers). Also, pain and inadequate analgesia are risk factors for delirium. Pupillary reflex changes and their identification by automated pupillometry have yielded positive results regarding nociception assessment in adult and pediatric patients and in perioperative and postoperative care. At the same time, the response of these patients to opioid administration was investigated. The aim was to improve their analgesia. The aim of this study is to find out whether, there is an association between automated pupillometry and selected objective pain measurement scales in The Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) positive patients after surgery.
