Active clinical trials for "Pain, Postoperative"

Effect of Using Nanochitosan versus Calcium Hydroxide as Intracanal Medications on the Postoperative Pain and Apical Bone Healing

This study will compare continuous intravenous lidocaine against single-injection transversus abdominis plane (TAP) block as a modality for postoperative analgesia in kidney transplant surgery.

To study and evaluate the Effectiveness of Treatment by Percutaneous Electrical NeuroStimulation (PENS) for post-operative pain in Cesarean Section patients using First Relief

This is a randomized, double-blinded study to evaluate the analgosedative effect of ketamine in a surgical intensive care unit. The patients who will receive continuous fentanyl infusion for either pain control or sedation will be recruited in this trial. Fentanyl will be titrated with initial loading doses of 20 mcg until the numeral rating scale(NRS) less than 4 or critical care pain observation tool (CPOT) less than 3 or Richmond agitation sedation score (RASS) -2-0. Then the patients will be randomised in to receive saline infusion in control group (Group C) or ketamine infusion in ketamine group (Group K). Ketamine will be administered with an initial bolus of 0.3 mg/kg followed by a perfusion of1.5 mcg/kg/min during the first 48 h. The dose of fentanyl will be protocolized adjusted according to NRS or CPOT or RASS.

Hysterectomy (removal of the uterus) is the most common major gynecologic surgery performed in Canada. With a focus on minimally invasive techniques and optimization of peri-operative pain control, gynaecologists have made great strides towards reducing hospital stay and accelerating post-operative recovery. These are essential achievements, both for patients and their families and for our resource-limited public healthcare system. Optimization of peri-operative pain control is multifactorial and includes, for example, administration of pre-operative analgesics, infiltration of incision sites with local anesthetic and provision of post-operative pain medications. As the understanding of pain mechanisms evolves, the incorporation of intra-operative nerve blocks has become yet another effective strategy to reduce post-operative pain. The presacral nerve plexus, which carries nerve fibers from the uterus to the brain, is an important pathway that transmits midline pelvic pain in women. Destruction of the pre-sacral nerves has been shown to provide excellent pain control in a variety of clinical settings. While transection of the presacral nerve at the time of surgery is technically challenging, instilling a presacral nerve block is surprisingly straightforward making this technique safe to perform in the hands of many gynecologists. In this technique, local anesthetic is instilled into the presacral space using a needle inserted through the abdomen. Given that the presacral nerve plexus is an integral pain pathway for the uterus, the investigators hypothesize that the addition of a presacral nerve block during laparoscopic (camera surgery) hysterectomy would confer an additional reduction in immediate post-operative pain. The proposed study therefore aims to look at the impact of presacral nerve block versus a sham (blank) block on immediate post-operative pain in a group of women scheduled to undergo laparoscopic hysterectomy.

This clinical study is designed to assesses the benefit of adding pulsed shortwave therapy to the postoperative pain and recovery protocol following Cesarean section. Pulsed shortwave therapy is a safe adjunct pain therapy for acute and chronic pain.

Women undergoing elective cesarian section will be assigned to 3 groups for postoperative analgesia: Scheduled doses of IV acetaminophen + PO Ibuprofen Scheduled doses of PO acetaminophen + PO Ibuprofen "On demand" doses of acetaminophen, dipyrone and ibuprofen.

Patients undergoing total hip arthroplasty may experience severe postoperative pain. This is normally treated with opioids, which can cause side effects such as nausea, vomiting, obstipation and sedation. The hypothesis is that patients receiving peripheral nerve blockade of three nerves leading pain stimuli from the hip will experience less pain, will consume less opioid and therefore have less side effects, and will be mobilized more quickly than patients not receiving the peripheral nerve blockade.

Postoperative pain following tonsillectomy or adeno-tonsillectomy in children is severe and sometimes last for days. Sufentanil is used by epidural route for postoperative analgesia in children. There are few reports about its use for postoperative analgesia by continuous intravenous infusion. Its complications include , hypoxia, sedation, pruritus ,nausea and/or vomiting. The investigators design this protocol to test efficacy of analgesia of three different rates of continuous intravenous sufentanil infusion for postoperative pain management following coblation tonsillectomy or adeno-tonsillectomy in children. The investigators also compare incidence rate of complications for three groups.

20-SMI-2013 is a post market, observational, questionnaire based study to assess the effectiveness of the commercially available Axium neurostimulator in the management of chronic post surgical pain
