Active clinical trials for "Pain, Postoperative"

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.

All anesthetic techniques aim to lessen intra-operative surgical site bleeding because it is a major problem and does not help with precision, surgery time, or postoperative wound healing. The main reason for reoperation and mortality in children who have had tonsillectomies is post-tonsillectomy hemorrhage. Pre-emptive analgesia reduces surgical pain blocking of central sensitization by topical or systemic medications.

Comparison of different postoperative analgesia after laparoscopic colorectal surgery

This study will use group-based trajectory modeling to identify the different postoperative pain trajectory groups that exist in a mixed surgical population (non-cardiac surgery) of elderly patients during the first seven days after surgery. The aim of this study is to explore the diversity in the development of postoperative pain among elderly patients and to identify the risk factors for acute pain trajectory after surgery by investigating demographic, psychological, and clinical variables. The predictive effect of different trajectories of early postoperative acute pain on postoperative chronic pain will also be explored.

Laparoscopic cholecystectomy is one of the most common operations in abdominal surgery. Effective analgesia in the postoperative period; It is of great importance in terms of acceleration of recovery, prevention of atelectasis, reduction of endocrine and metabolic stress response, reduction of thromboembolic complications, protection of cognitive functions, prevention of chronic pain development, and reduction of hospital stay . Intravenous paracetamol, NSAID/cyclooxygenase-2 selective inhibitors, opioids, local anesthetic infiltration in the port area, intraperitoneal local anesthetic insufflation or plan blocks can be used in the treatment of postoperative pain after laparoscopic cholecystectomy. Operation, tissue trauma, anesthesia, drugs given to the patient, type of anesthesia, blood loss, temperature changes and pain cause postoperative stress response

The goal of this clinical trial is to evaluate the effect of the addition of nefopam to a multimodal analgesic regimen consisting of ketoprofen and paracetamol during sevoflurane- dexmedetomidine-based anesthesia on postoperative morphine requirements in patients undergoing laparoscopic cholecystectomy.

The study will be designed to investigate the effect of pupillometry guided compared to non-PPI-guided postoperative pain therapy, conducted immediately at the end of surgery before extubation, on total postoperative opioid consumption during the first 2 postoperative hours after elective ear nose throat (ENT) surgery.

The purpose of this study is to compare the effect of pregabalin in reducing the neuropathic pain in postoperative patients who have undergone single level Microdiscectomy for prolapsed intervetebral lumbar disc.

The aim of the study is to test the effectiveness and safety of the use of lidocaine infusion in multimodal analgesic management. A group of patients undergoing vascular surgery performed with the classic technique on the aorta - with the opening of the abdominal cavity will be enrolled. The population of patients qualified for this type of vascular surgery is usually burdened with multiple diseases, mainly risk factors or cardiovascular diseases, which, combined with hemodynamic fluctuations, large fluid shifts (including bleeding) and stress for the body, affects the risk of serious cardiological complications, which in this group exceeds 5% and is the highest, according to the ESC / ESA (European Society of Cardiology / European Society of Anesthesiology) classification from 2014. Proper postoperative pain control is therefore becoming one of the key pillars of postoperative care in this group of patients. Due to the numerous disease burden of patients and the operational specifics, the use of multimodal therapy in the management of pain is of particular importance, as the use of high doses of opioids improves hemodynamic stability, but at the same time affects the occurrence of side effects - mainly excessive sedation, respiratory disorders, hypoventilation and, consequently, for hypoxia of the heart muscle. The risk of myocardial injury in non-cardiac surgery (MINS) is significant in the light of the available literature. Lidocaine used in intravenous infusion is one of the recommended components of multidirectional analgesia. Its adjuvant properties make it possible to reduce the amount of opioid drugs used, and thus - to reduce the frequency of their side effects. The high effectiveness of such a procedure has been proven in numerous experimental and epidemiological studies. Due to the low frequency of side effects associated with its use, the therapy has a strong recommendation for use in relieving perioperative pain. The analysis of the literature on the subject shows that there is little data assessing effectiveness of lidocaine infusion in relation to the group of patients after surgery on the abdominal aorta.

This research study is being done to determine the optimal dose of spinal morphine and hydromorphone in patients undergoing minimally-invasive (i.e., surgery performed through small entry sites and using cameras) colorectal surgery.
