Active clinical trials for "Pain, Postoperative"

The research is designed as a single-center, prospective, randomized double-blind study. The patients undergoing shoulder arthroscopy surgery in Istanbul University, Istanbul Faculty of Medicine, Department of Orthopedics and Traumatology will be included. Patients who are legally authorized to make decisions on their behalf will be informed about the research and their written consent will be obtained. Patients who do not give consent will be excluded. Ultrasonography (USG) guided combined suprascapular and axillary block will be performed routinely for postoperative analgesia. After the block is performed, general anesthesia will be applied. The patients will be divided into 4 groups. Three different doses of local anesthetic will be given to patients (30 cc vs 20 cc vs 10 cc). Local anesthetic dose will be the same for suprascapular and axillary blocks. The fourth group will be sham control. Pain score will be determined by visual pain scoring (VAS) and analgesic consumption will be provided by the use of a patient controlled analgesia (PCA) device with intravenous morphine applied in routine practice to all four groups at the postoperative 1, 4, 8,12 and 24 hours. Patient will be observed for postoperative nausea and vomiting, first time to mobilization, length of hospital stay, analgesic consumption and satisfaction of surgeon and patient.

General anesthesia is a combination of hypnotic drugs and opioid analgesics. Modern general anesthesia aims to treat nociception induced by surgical stimulation while avoiding an overdose of opioid analgesics and reducing side-effects of opioid administration. Quality and safety of general anesthesia are of major clinical importance and can be improved by adjusting the opioid analgesics to the optimal individual dose needed. In the current clinical practice, the opioid dosage is usually chosen by clinical judgment, though recently different monitoring devices estimating the effect of nociception during unconsciousness have become commercially available. Nevertheless, the impact of nociception-monitor-guided opioid administration on the administered amount of opioid, postoperative short-term recovery, and long-term outcome is inconclusive. This study aims to investigate the predictive power of different nociception monitoring systems for the prediction of moderate to severe immediate postoperative pain from nociception indices measured before awakening from general anesthesia.

Observational study that evaluate the cardiovascular and neuropsychiatric side effects of ketamine analgesic infusions for acute pain

Pain is common for the first 2 days after major craniotomy. Inadequate analgesia induced sympathetically mediated hypertension may lead to an increased risk for post-operative complications, such as arterial hypertension, intracranial hemorrhage, prolonged hospital stay, and mortality.Pain after craniotomy derives from the scalp and pericranial muscles.Scalp block with local anesthesia seems to provide effective and safe anesthetic management.Scalp block can be performed by directly blocking the six different nerves that provide the sensory innervation of the scalp in neurological surgery.Even if adrenaline as an additive agent, scalp block using 0.5% or 0.75% bupivacaine with adrenaline could only improve postoperative analgesic for up to six hours after craniotomy.However, pain is common for the first 2 days after major elective intracranial surgery, and the relatively short analgesic time of scalp nerve blocks does not seem to meet the requirements of craniotomy. Therefore, how to improve the quality and duration of scalp nerve blocks with local anesthetics is of great significance.Parecoxib is a NSAIDs that specifically inhibits the enzyme COX-2.Liu et al firstly applied parecoxib as an adjuvant to local anesthetics on peripheral nerve blocks and reported 20 mg parecoxib added to ropivacaine injected locally on the brachial plexus nerve prolonged the motor and sensory block times of the nerve blockade and ameliorated postoperative pain intensity for patients receiving forearm orthopaedic surgery. However, there has not been reported about local application of parecoxib on scalp nerve blocks. The investigators postulate that parecoxib may be also ideal for scalp nerve blocks for relief of post-craniotomy pain, and further research is needed. The APONIA trial aims to establish whether scalp blocks with a mixture of ropivacaine plus parecoxib is able to relieve patients' postoperative pain compared with local anesthetics alone, thereby potentially changing medical practice.

This study will collect perioperative pain-related data of elderly patients in multi-centers. Analyzing these collected data to find the high-risk factors of chronic postsurgical pain in elderly patients and to establish an early-warning models of perioperative pain in elderly patients, so as to improve the ability of assessing the risks of postoperative pain in elderly patients and providing an early warning. Based on the database, the investigators intend to explore: Perioperative risk assessment methods and early warning models for elderly patients; Practical, safe, and effective risk prevention and control system through subsequent studies.

Management of pain after caesarean section represents an important anesthesiologic issue, since it is often suboptimal, leading to delayed functional recovery and chronic pain. Currently, the postoperative analgesic strategy mostly relies on intrathecal morphine (ITM) and multimodal analgesic regimen. Recently, the need for alterative opioid sparing techniques is emerging. Paraspinal fascial plane blocks, as quadratus lumborum block (QLB) and erector spinae plane block (ESPB) performed at T9 level, have therefore been proposed as alternatives to ITM, because of their demonstrated effect on visceral and somatic pain. The aim of the study is to assess the efficacy, the feasibility and safety of bilateral ESPB compared to bilateral QLB for the management of postoperative pain after ceasarean section conducted under spinal anesthesia without ITM.

This prospective double blinded study will be conducted over 60 pediatric patients ASA (American Association of Anesthesiologists) I and II between the age of 1-7 years old, who will be scheduled for unilateral groin surgery. Patients will be randomly allocated into 3 study groups: Control group that only received local anesthetics ( bupivacaine) Group II bupivacaine with the dexmetedomidine ( 0,5mcg/kg ) and group III bupivacaine with the dexmedetomidine (1mcg/kg).Patients in all groups will receive quadratus lumborum block. Bradycardia, hypotension, atropine, and bolus fluid infusion requirements will be recorded. When there was up to a 30% decrease in basal mean blood pressure, a crystalloid infusion bolus will be given at 10 ml/kg. When bradycardia occurred , atropine will be given at a dose of 0.02 mg/kg. Patients will be followed up in the postoperative recovery unit for the first 2 hours, and then in the ward. The RAMSEY sedation scale and WATCHA agitation scale were evaluated at 5, 15, 30, and 60 minutes in the postoperative recovery unit. Nausea, vomiting, and other side effects were recorded if present. Time to first analgesic requirement ( primary outcome) , FLACC Scale scores will be recorded within 24h postoperatively, total dose of analgesic consumption, incidence of postoperative complications as hypotension, bradycardia, vomiting, pruritis and respiratory depression will be recorded.

The importance of effective postoperative pain management is well known. Overall, for total abdominal hysterectomy operations are related with severe postoperative pain. The undesired effects of pain can be prevented with multimodal analgesia for the patient. Many regional anesthesia techniques can be preferred for total abdominal hysterectomy. The aim of this study is to investigate postoperative analgesia effect of erector spina plane block for total abdominal hysterectomy.

This study aims to compare the effectiveness of preoperative ultrasound-guided suprainguinal fascia iliaca compartment block (SFICB) and pericapsular nerve group block (PENG) in preventing positioning pain during spinal anesthesia in patients who are scheduled for surgery due to hip fracture.

In our study, three different medicaments were evaluated in terms of postoperative complications after free gingival grafting (FGG).
