Active clinical trials for "Pain, Postoperative"

Laparoscopic cholecystectomy (LC) is a widespread surgical procedure with superior outcomes in terms of the incurred postoperative pain, recovery time, cosmetic, and morbidity issues. Although it is associated with less postoperative pain compared to open cholecystectomy, but patients still experience significant pain. Pain after LC is categorized into three types: referred pain to the right shoulder due to diaphragmatic stretching during gas insufflation; visceral pain due to dissection and injury at the hepatic fossa during gall bladder removal; and somatic pain due to tissue injury at the port sites. Since the discovery of LC in 1987 by a French surgeon, Phillipe Mouret, it became the gold standard for surgical excision of the gallbladder. Local anesthetics (LA) has been tried for analgesia after LC in variable techniques and concentrations. It was proved to be a safe and valid method for reducing pain after LC instilled intraperitoneal and infiltrated at the port sites. Surgicel is an absorbable gelatin sponge that is non-toxic, non-allergenic, non-immunogenic, and non-pyrogenic. It is gamma-sterilized and provided with double packing. The sponge is easily cut to fit the surgical cavity. It may be applied dry to the wound. It absorbs 40 times its weight of whole blood or 50 times of water and adheres easily to the bleeding site. It forms a stable adherent coagulum. When implanted in vivo, it is completely absorbed within 3-5 weeks. The rationale for using this sponge as interposition material is to act as a carrier for the analgesic drugs and allow for its local sustained release, and for local hemostasis. Bupivacaine will be used as the main local anesthetic medication in the study. It provides variable pain relief when either used to irrigate intraperitoneal space as a sole analgesic or combined with opioids. Lidocaine 2% will be mixed with bupivacaine to expedite the onset of analgesia. Epinephrine will be used as 5 microgram/ml of the total mixture of used fluids in order to prolong the time of action of the block.

Patients will be randomized into 2 groups: Vit E group: Vitamin E ointment will be applied over staple lines and anastomoses Control group: Vitamin E will not be applied Postoperative pain will be assessed 24 hours after surgery.

The purpose of this randomized clinical study was to evaluate the impact of occlusal reduction on the incidences of post-instrumentation and post-obturation pain. Forty four patients were included in this study. Inclusion criteria were posterior mandibular teeth having symptomatic irreversible pulpitis and symptomatic apical periodontitis. Patients were randomized into two equal groups. In the intervention group the functional and nonfunctional cusps were reduced until absence of contact was confirmed, while in the control group the occlusal surfaces were left intact. Standard endodontic treatment was performed in two visits using rotary nickel titanium files for shaping, 2.5% sodium hypochlorite for cleaning and lateral condensation technique with resin sealer for obturation. Pain was assessed preoperatively, then after 6, 12, 24 and 48 hours following instrumentation, then after 6 and 12 hours following obturation. Visual Analogue Scale (VAS) was used as the primary outcome measure. Patients were given a placebo to be administrated in case of severe pain and ibuprofen 400mg was prescribed in case of persistent pain.

This is a single centred randomized controlled trial comparing surgeon versus anaesthetist inserted rectus sheath catheters for management of analgesia post major abdominal surgery.

Objectives:Lomber disc hernia is one of the most common diseases in Turkey. The prevalence in various studies is between 60-80% and incidence is between 1-3% for the entire population,Goal of TLIP is to provide a same impact in the thoracolumbar region, like thoracoabdominal plane block (TAP) diminish the pain in the abdominal surgery Methods: The study design was approved by the locale ethics committee. This double-blinded, randomized, controlled clinical trial recruited 50 patients who were candidated for surgical operations on lumbar disc hernia surgery. . Patients will be divided into two groups as Group T (TLIP block) and Group E (Epidural group).In group T, TLIP block will be applied before anesthesia and surgery and evaluate block efficiency with temperature discrimination and pin-prick test. During the TLIP block, block fluid will have total volume of 20 mL of 0.5% bupivacaine.). In Group E, after surgery, total of 20 ml of 0.1% bupivacaine and 50 mcg of fentanyl will be performed in the epidural space with direct vision by the surgeon.For the postoperative analgesia, patient controlled analgesia device will be administered as 20 mg/h continue dose tramadol and administered 10 mg bolus dose tramadol if patient need a rescue dose. Nausea-vomiting, tramadol consumption, bolus dose intervention and visual analog scale value in the postoperative 0-4., 4-12., and 12-24. hour interval will be assess and results will be record.

Postoperative pain, the quality of their recovery and the opioid consumption following a midurethral sling placement are being compared between 2 groups. One group will have the hydro-dissection performed with a diluted liposomal bupivacaine solution. The other group will have the hydro-dissection performed with a diluted bupivacaine HCL and Lidocaine solution.

Ankle arthritis is associated with debilitating pain and chronic disability. For the treatment of severe ankle arthritis, total ankle arthroplasty (TAA) is one treatment option. Postoperative pain management in joint arthroplasty is an ongoing and relevant issue. The purpose of this study is to examine if differences exist in postoperative pain control, overall patient satisfaction, and use of narcotics using an intra-articular injection in the operating room compared with a peripheral nerve block in patients undergoing TAA.

This study aims to determine if intravenous Dexamethasone combined with a pudendal nerve block is able to prolong postoperative analgesia in children undergoing hypospadias repair.

this prospective parallel group double blinded study will be conducted over 50 pediatric patients ASA (American Association of Anesthesiologists) I and II between the age of 8-13 years old,who will be scheduled for laparoscopic pyeloplasty.Patients will be randomly allocated into 2 study groups: Quadratus lamborum dexmedetomidine intravenous group(QD IV group) and Quadratus lamborum dexmedetomidine perineural group(QD PN group.Patients in both groups will receive quadratus lamborum block .In QD IV group a bolus of 0.5 ml/Kg bupivacaine 0.25% in addition to 2ml normal saline will be injected then dexmedetomidine.1ml/kg loading dose will be given over 10 min followed by 0.5 ml/kg/h infusion maintenance dose till the end of surgery. In QD PN, patients will receive perineural dexmedetomidine of 1μ g/kg diluted to 2 mL with 0.9% saline added to 0.5 ml/kg of 0.25% bupivacaine in addition to saline infusion 1ml/kg IV loading dose followed by by 0.5 ml/kg/h infusion maintenance dose till the end of surgery.Time to first analgesic requirement ( primary outcome) , Wong-Baker FACES Pain Rating Scale scores will be recorded at 2, 6, 8,12, 18 and 24h postoperatively, the degree of sedation will be assessed by Ramsay sedation scores(fig.2)(9) at the same time points, hemo-dynamics as systolic and diastolic blood pressures and heart rates will be recorded at PACU discharge then 4 hourly, total dose of morphine consumption, , the length of hospital stay, incidence of postoperative complications as hypotension, bradycardia, vomiting, pruritis and respiratory depression

In this study, based on the hypothesis that dexmedetomidine administered intraoperatively for sedation can reduce postoperative pain than that of propofol, the investigators examined the ability of dexmedetomidine to reduce postoperative pain in in patients undergoing the total knee arthroplasty.
