Active clinical trials for "Pain, Postoperative"

The moderate-to-severe pain many patients experience following surgery is often treated with opioids, which are associated with side effects such as nausea/vomiting, sedation, and respiratory depression (and a risk of abuse, dependence, and diversion). Potent site-specific analgesia with fewer side effects may be provided with peripheral nerve blocks. However, these too have limitations such as a duration of action measured in hours, while the pain from surgery is usually measured in days or weeks. Peripheral nerve stimulation or "neuromodulation" is an alternative method of pain control involving the introduction of electrical current to stimulate various nerves that do not carry pain sensations, but which then decreases communication between pain fibers and the spinal cord and/or brain. Placing small electrodes specifically in the area of the ear is called "auricular neuromodulation" and is theorized to function by stimulating various cranial and peripheral nerves that influence a part of the brain called the "limbic system" which is involved with many aspects of behavior including responses to stress. A device that delivers auricular neuromodulation, the "Bridge" system, is approved by the United States Food and Drug Administration for use to reduce symptoms associated with opioid withdrawal for up to 5 days. However, one prospective and two published retrospective studies suggest that it may provide postoperative analgesia as well. The device itself is relatively simple to apply; has few contraindications, side effects, or adverse events; and has no potential for dependence, abuse, or diversion. Therefore, it has the potential to concurrently improve analgesia and decrease or even negate opioid requirements following surgery, only without the limitations of opioids and peripheral nerve blocks. The purpose of this pilot study is to explore the possibility of treating postoperative pain with percutaneous auricular neuromodulation, optimize the study protocol, and estimate the treatment effect in preparation for developing a subsequent definitive clinical trial.

One hundred and twenty patients at age range from 18 to 60 undergoing laparotomy was enrolled in this study. Patients were randomly assigned to two groups 60 in epidural group and the other 60 patients in rectus catheter group. epidural catheter inserted pre induction but rectus sheath catheter inserted by the surgeon at the end of surgery.

The aim of this randomized one-blinded study will be to evaluate the efficacy and tolerability of two different oral doses of tapentadol and compare it to tramadol (an opioid commonly used to treat post-surgical pain) in cardiac surgery patients

The aim of this study will be to investigate the effect of an opioid-free anesthesia regimen with a mixture of dexmedetomidine-lidocaine-ketamine in the same syringe versus fentanyl analgesia in elective laparoscopic cholecystectomies

This study is a double-blind, randomized, prospective, placebo-controlled single-center clinical research study in which 600 mg of gabapentin or placebo will be administered 2 hours preoperatively to 49 patients each undergoing wisdom teeth extraction. We will measure intraoperative opioid use, severity of pain, the number of analgesics taken, and side effect profiles (e.g. nausea/vomiting, dizziness) at the following intervals, 4 hour, 8 hour, 12 hour, 24, and 72 hour post-procedure.

The purpose of this study was to make sure whether the infiltration of dexmedetomidine around the uterus can reduce the pain of cesarean section surgery.Studies have shown that the use of local anesthetic infiltration around the uterus can reduce pain after cesarean section surgery.In observed group, 50ug of dexmedetomidine (volume 10ml) was infiltrated around the uterus at the end of the caesarean section, while in controled group, 10ml normal saline as placebo was infiltrated around the uterus. VASs was accessed in 2h 12h,24h,48h after surgery.

This study will evaluate whether or not wearing a virtual reality (VR) headset reduces pain and anxiety in patients undergoing vasectomy. The headset being used is the SmileyScope virtual reality interface, a device already undergoing study for approval by the U.S. Food and Drug Administration (FDA) to reduce pain and anxiety in patients aged 4 years and older undergoing needle blood draw or injection procedures. In this study, the SmileyScope virtual reality interface is considered an investigational device because it is not yet approved for use in adult males undergoing vasectomy.

The aim of this double blind randomized study will be to investigate the effect of an opioid-free anesthesia regimen with a mixture of dexmedetomidine-lidocaine-ketamine in the same syringe versus remifentanil analgesia in lumbar spine surgery

The aim of this double-blind randomized study will be to evaluate the effect an intravenous infusion of magnesium has on recovery outcomes after elective laparoscopic cholecystectomy

To compare the efficacy of USG-guided bilateral External oblique intercostal (EOI) block with Erector spinae plane block (ESPB) for post-operative analgesia after laparoscopic cholecystectomy with a hypothesis that both External oblique intercostal fascial plane block and Erector spinae plane block are effective in providing post-operative analgesia.
