Active clinical trials for "Pain, Postoperative"

Total knee arthroplasty (TKA), also known as a knee replacement, is a procedure performed to reduce severe pain and improve function of the joint. Managing postoperative pain can be challenging following TKA, and inadequate relief can lead to impaired mobility and persistent opioid use. Adductor canal nerve blocks (ACB), have shown significant benefit in improving postoperative analgesia and patient satisfaction. However, the local anesthetic used currently for these blocks only provides temporary relief that wears off within 24 hours. Liposomal bupivacaine is an extended-release local anesthetic agent that can provide up to 72 hours of pain relief, however it is unclear if its use is also effective in ACBs for knee surgery. The purpose of this study is to determine if liposomal bupivacaine is better than conventional bupivacaine in improving pain control, opioid consumption, and length of stay in patients scheduled for TKA.

Perioperative and postoperative pain control in pediatric patients is a frequently neglected issue. Regional anesthesia applications reduce adverse drug events by minimizing opioid consumption and provide effective and safe analgesia. In recent years, quadratus lumborum block has emerged as an alternative regional anesthesia technique and it has been shown to provide analgesia as effectively as caudal block in children, and in a limited number of studies it has been said that it is more effective than transversus abdominis plane block. There are few studies in the literature comparing ilioinguinal iliohypogastic nerve block and quadratus lumborum block in children.

Introduction: This study aimed to compare postoperative pain rates following sodium hypochlorite (NaOCl) and KTP laser-assisted pulpotomy treatments in permanent teeth with deep caries, and symptomatic irreversible pulpitis. Methods: Ninety patients complaining of permanent teeth pain due to symptomatic irreversible pulpitis were randomly divided into 3 equal groups. Preoperative pain levels were recorded. After the initial bleeding control was achieved with saline, complete hemostasis was achieved by applying saline (control group), 2.5% NaOCl, or KTP laser according to randomly determined patient groups. Patients were asked to mark their pain level on the visual pain scale at the 6th, 24th, 48th, and 72nd hours, and 7th and 30th days depending on the severity of the pain. The permanent restoration was completed after 7 days. Results: According to the present study, the statistical difference between the groups in terms of preoperative pain and percussion pain levels was insignificant. There was no significant difference between the groups in terms of demographic data. The postoperative pain level of the KTP laser group was significantly lower at the 6th hour compared to the saline group. There was no significant difference between the groups in terms of postoperative pain level at other time intervals. The greatest pain scores occurred in all groups at 6th hour. Conclusions: KTP laser can be preferred primarily in reducing postoperative pain in pulpotomy treatments. KTP laser or NaOCl assisted pulpotomy can be an effective treatment for pain reduction in permanent teeth with symptomatic irreversible pulpitis.

Lumbar spinal surgery, one of the most common operations for the treatment of back and leg pain, is a painful postoperative procedure. Pain control is an important part of the treatment in these patients who may develop chronic pain. In patients undergoing surgery for lumbar disc herniation (LDH), severe pain may occur in the postoperative period, especially in the operation area, and this pain may become chronic. The subject of our study is to observe the effect on the use of analgesics by randomizing the patients that we routinely block in this painful procedure. We aimed to evaluate the analgesic efficacy of two different regional analgesia methods performed under ultrasound guidance in patients undergoing lumbar spinal surgery.Thoracolumbar interfacial plane (TLIP) block is a regional analgesia technique performed under US guidance, which was defined by Hand et al. in 2015 (10). Ueshima et al. retrospectively demonstrated that this technique produces effective analgesia after lumbar laminoplasty. reported in their study (11). In the classical technique, local anesthetic infiltration is performed between the Multifidus and Longissimus muscles in the 4th Lumbar (L4) vertebral region (10). There is no study in the literature comparing classical TLIP block and QL2 block. In this study, it was aimed to compare the effectiveness of US-guided Classic TLIP block and Posterior QLB (QL2) block for postoperative analgesia management after LDH surgery. Our primary aim is to determine the 24-hour opioid requirement, and our secondary aim is to; to compare postoperative pain scores (NRS), to evaluate side effects (allergic reaction, nausea, vomiting) associated with opioid use and complications that may occur due to block.

The purpose of this prospective cohort study is to evaluate the opiate prescribing patterns post open reduction and internal fixation (ORIF) of wrist and ankle fractures at the Ottawa Hospital. The primary objective would be to examine the quantity and duration of opiates consumed by the study population, as well as the participant's overall satisfaction with pain control. the investigators will assess whether there is a discrepancy between the quantity of pills prescribed and what is being consumed. With the data collected, the secondary objective would be to create a standardized pain prescription, which the investigators would implement in the second phase of this prospective study. Opiate pills consumed, pain satisfaction and left-over narcotics would again be assessed. The overall goal of this study is to produce an appropriate standardized post-operative prescription, where the number of opiates prescribed mirrors what is being consumed. This would cut down on the quantity of left-over narcotics, helping to reduce the incidence of opiate dependency and diversion in the Ottawa community.

Total intravenous anesthesia (TIVA) is maintained by intermittent or continuous combined intravenous injection of a variety of short-acting intravenous anesthetics, which can provide safe and rapid induction, maintenance and termination of general anesthesia. It has a slight effect on respiration and circulation, strong controllability, short anesthetic recovery time, reduced postoperative nausea and vomiting (PONV) and quick discharge time, so it has been widely used in clinic. Functional endoscopic sinus surgery is a common method for the treatment of sinusitis and other diseases. The trauma of this operation is less. The use of TIVA during the operation can reduce the bleeding in the surgical field and is beneficial to the recovery of patients. The combination of propofol and remifentanil is the most common in TIVA because of its fast pharmacokinetics and short half-life. However, the disadvantage of remifentanil is the lack of residual analgesic effect after termination of continuous infusion. As postoperative nasal packing can still bring postoperative pain, patients with severe discomfort caused by pain will have unexpected conditions such as surgical incision cracking and bleeding, which will affect the effect of operation and rehabilitation. Afentanil is another opioid drug with short effect and strong analgesic effect. Previous studies have shown that remifentanil-based TIVA has slightly higher postoperative pain and early use of analgesics than TIVA in discectomy. Because the effect of TIVA using Afentanil or remifentanil on postoperative pain in functional nasal endoscopic surgery is not clear, this study intends to observe the effect of TIVA on postoperative pain in patients undergoing functional nasal endoscopic surgery under general anesthesia, so as to optimize the clinical anesthetic scheme of this kind of minimally invasive surgery and provide clinical reference.

Primary aim of this prospective, randomized, double-blind clinical trial is to compare the analgesic effects of intravenous paracetamol and ibuprofen on postoperative pain, and secondary aim is the effects on tramadol consumption and side effects of tramadol in patients who underwent unilateral shoulder surgery.

To compare the post cranioplasty pain score using scalp block versus conventional analgesia using IV Parecoxib and requirement of morphine between two groups as rescue analgesia
