Filter by:In this study the investigator will compare the effectiveness of robot assisted thoracic surgery (RATS) with video assisted thoracic surgery (VATS) in case of lung cancer. The perioperative circumstances and postoperative outcome will be compared.
Painful osteoarthritis (OA) is the 4th largest cause of disability in the UK. Preoperative temporal summation, a measure of central pain facilitation, has been shown to predict postoperative pain after total knee replacement surgery (TKR). The assessment of the brain's response to noxious stimuli using non-invasive functional MRI (fMRI) may be key in identifying imaging biomarkers within the brain that map central sensitization changes seen in OA. fMRI may help explain why up to 20% of patients undergoing TKR surgery develop persistent post-operative pain. To test these concepts the study aims to functionally characterise the brain activity related to temporal summation of pain in healthy individuals and OA patients using a novel fMRI cuff algometer. Assessment of outcomes in terms of pain and function will be performed 6 months post TKR surgery
Opioids have been used for analgesia since many years, but despite potent analgesia they are also associated to side effects, including opioid induced Hyperalgesia (OIH). OIH in the surgical setting is debated, and may predispose patients to higher analgesic consumption in the preoperative period, and peripheral and central sensitization. The aim of the study is to compare remifentanil-based vs non opioid analgesia (clonidine, lidocaine, ketamine) for intraoperative management of patients undergoing laparoscopic left hemicolectomy, with the hypothesis that non- opiod treated patients will have lower morphine consumption in the first 24 hours after surgery. Peripheral and central hyperalgesia will be tested with Von Frey hairs and pin-prick to evaluate acute CNS (Central Nervous System) sensitization after surgery. Acute and persistent (1 and 3 months) pain will be registered, together with any side effect and parameters of surgical rehabilitation.
In this study, investigators aimed to compare the Quadratus Lumborum Block and the Transversus Abdominis Plan Block for postoperative pain control after laparoscopic cholecystectomy
The investigators want to test the hypothesis that the addition of a recruitment manoeuvre to a low pressure pneumoperitoneum will lead to an additional reduction in postoperative pain. Therefore the investigators will conduct a prospective randomized controlled, single blind trial.
This study will evaluate two different analgesic regimen used for acute postoperative pain.
Total knee arthroplasty (knee replacement) is a common orthopedic procedure for osteoarthritis. This procedure is performed either under general anesthesia or spinal anesthesia; after the procedure in the recovery room, these patients undergo adductor canal block, which is a nerve block to provide 8-14 hours of postoperative pain control. For this nerve block, 15-20 ml of local anesthetic is combined with adjuvant medications to improve the quality of pain control as well as the duration of pain relief. The primary local anesthetic used for adductor canal block is ropivacaine, and the commonly used adjuvants are epinephrine and dexamethasone. There is conflicting data available in the literature regarding efficacy of addition of clonidine to the local anesthetic injection in peripheral nerve blocks, and there is no data assessing the efficacy of this medication in adductor canal blocks. Once the consent process is completed, patients are enrolled in two arms. Upon conclusion of surgery, a sealed and coded envelope with either clonidine or the placebo syringe will be given to the acute pain service staff performing the nerve block. This will be mixed with local anesthetic solution and injected in the adductor canal under ultrasound guidance. The primary outcome measure will be the duration of analgesia, which will be assessed as the time interval between placement of adductor canal block to the first request of opioid analgesic by patients (which will be obtained from hospital electronic medical records). Secondary outcomes will include: 1. Duration of sensory block, which will be assessed as the time interval between injection of local anesthetic and report of postoperative pain of 3 or more on an 11 point scale (0=no pain; 10= worst pain imaginable) by the patient (this will be assessed every 4 hours). 2. Duration of motor block, which will be assessed as the time interval between the onset of motor block to complete recovery of motor block by assessing straight leg raise strength (this will be assessed every 4 hours). 3. Cumulative 24 and 48 hour opioid analgesic use. 4. Post-block pain scores, evaluated by an 11 point pain score (0-10), which will be done every 15 minutes for the first hour after surgery and every 4 hours thereafter for 24 hours.
The authors study the efficacy of the pudendal versus penile block for the relief of postoperative pain in children receiving ambulatory circumcision. In this prospective, double-blind, randomized, parallel-arm trial, 60 children recruited during the anesthesia consultation will be allocated a general anesthesia with a pudendal block (PUD group) or a penile block (PEN group). Each block will be made with equal parts lidocaine 1% and ropivacaine 0.75% (0.3 ml/kg).
The purpose of this study is to investigate the analgesic effect of low-dose intravenous ketamine in pregnant mothers undergoing cesarean section under Bupivacaine spinal anesthesia.
The purpose of this study is to determine if the infiltration of 0.5% Bupivacaine in the surgical wound is effective to diminish the pain and the risk of surgical site infections in patients who go to a open gastrointestinal procedure.
