Active clinical trials for "Pain, Postoperative"

Dexmedetomidine is a drug known for its pain-relieving and restlessness-reducing effects. The purpose of this run is to use the association between this use during surgery and the attrition of post-operative pain and discomfort. In the research, laboratory and monitoring results will be obtained before, during and after the operation. Postoperative patient complaints will be evaluated at the postoperative service visit. This study is decided on a completely voluntary basis.

This is a prospective randomized controlled trial that will assess preoperative, perioperative, and long-term oxidative stress (OS); pain; and functional outcomes over a 12 month period and test the hypothesis that a potent antioxidant intervention (glycine + N-acetyl-cysteine(GlyNAC)) reduces oxidative stress and chronic post surgical pain (CPSP) in patients undergoing total knee arthroplasty (TKA).

The aim of this study will be to compare the effects of morphine versus dexmedetomidine when used as adjuvants to local anesthetic (Ropivacaine) in Erector Spinae Plane Block under ultrasound guidance. A group without an adjuvant will also be compared to the groups.

It is widely believed that major lumbosacral spine surgeries are associated with severe postoperative pain that may delay the functional recovery of the patient. Caudal epidural injection (CE) has an important role in providing effective pain relief post lumbosacral spine surgeries by blocking sensory input at the level of the spinal cord. Erector Spinae Plane Block (ESPB) is a relatively new technique of trunk fascial block which was introduced in 2016. Reports showed that ESPB significantly relieved postoperative pain in patients with lumbosacral spine surgery, reducing the use of analgesics.The overall benefit of intravenous (IV) analgesia versus pre-emptive analgesia by caudal epidural or erector spinae block is still controversial. The aim of this study is to compare the pre-emptive analgesic effect of bilateral erector spinae plane block versus Caudal epidural analgesia versus the conventional intravenous analgesia in adult patients undergoing lumbosacral spine surgeries under general anesthesia.

The purpose of this study was to assess the safety and pharmacokinetics (single- and multiple-dose) of oxymorphone ER for the relief of moderate to severe pain in pediatric participants ages 7 - ≤17 years old requiring a continuous, around-the-clock (ATC) opioid treatment for an extended period.

The purpose of this study is to determine if a post-operative course of oral dexamethasone affects opioid usage in pediatric patients undergoing tonsillectomy. Patients who are scheduled to undergo tonsillectomy or adenotonsillectomy are randomized to receive either 1) a post-operative steroid course of oral dexamethasone in addition opioids, acetaminophen,NSAIDs or 2) opioids/acetaminophen/NSAIDS alone. All drugs are prescribed per approved FDA labeling. Children between the ages of 4-17 will be considered for enrollment. Participants (or with the aid of parents/legal guardian for subjects unable to complete on their own) will complete a diary twice a day to record pain medication administration and visual pain scale. Remaining steroid and opioid medication will be measured at the routine post-operative appointment that occurs 4 - 6 weeks following surgery.

The overall purpose of this study is to evaluate the analgesic efficacy of liposomal bupivacaine in optimizing pain control, minimizing the risk of postoperative nausea and vomiting (PONV), and improving recovery after abdominoplasty. This will be done by comparing intraoperative abdominal wall and incisional injection of bupivacaine to bupivacaine plus liposomal bupivacaine in 46 participants 18 years and older undergoing elective abdominoplasty. This will be studied using pain assessments, validated surveys, medication logs and review of medical records.

Orthognathic surgery is a procedure performed to correct dentofacial deformities. It involves osteotomy at the facial skeleton. Considerable pain is expected in the early recovery period. Melatonin is a hormone that is produced naturally by the body. Synthetic Melatonin is available over the counter for the management of sleeping disorder and jetlag. Clinically, Melatonin can also be used to reduce pain and analgesic consumption in patients undergoing surgery. Dexamethasone is a type of steroid. It can suppress the inflammatory response. It is an anti-inflammatory, anti-allergic drug. It is commonly used in head and neck and oral surgery for its anti-inflammatory effect to reduce swelling. This study aims evaluate the efficacy of oral melatonin in the pain reduction following orthognathic surgery. This is a double-blinded randomized controlled trial. We will recruit 87 patients who are scheduled for double-jaw orthognathic surgery to participate in this three-year study. The study lasts for 2 weeks. Participant will be randomly allocated by computer to one of the three groups. (1) Group D will receive dexamethasone only; (2) Group M will receive melatonin only; and (3) Group DM both melatonin and dexamethasone. Postoperative pain level and perioperative plasma levels of inflammatory markers and anti-oxidizing enzymes will be recorded and compared among the study groups.

Controlled clinical trial of two parallel groups, with random assignment 1:1, non-inferiority, blinded for the patient, for who administers the intervention and for who analyzes the data. 112 participants

Chronic postsurgical pain (CPSP) has an incidence of 46% in patients after breast cancer surgery, which seriously affects patients' physiological and psychological function, as well as quality of life. Acute pain is an independent risk factor for persistent pain after surgery. Erector spinae plane block (ESPB) provided excellent perioperative analgesia in patients undergoing breast surgery. Dexmedetomidine as an adjuvant of local anesthetics prolongs the duration of peripheral nerve block and decreases the requirements of postoperative analgesia. The investigators hypothesize that, for breast cancer patients undergoing mastectomy, ESPB (with a combination of 0.5% ropivacaine 35 ml and dexmedetomidine 1 microgram/kg) can reduce the occurrence of CPSP. The purpose of this randomized controlled trial is to investigate the impact of ESPB with adjuvant dexmedetomidine on the incidence of CPSP in breast cancer patients after mastectomy. We will also observe the impact of ESPB on long-term survival in these patients.
