Filter by:This phase III, randomized, prospective clinical study, aiming to compare the analgesic effects of celecoxib, parecoxib, and oxycodone in patients with inoperable hepatic carcinoma undergoing TACE procedure in postoperative pain control.
Propofol is a commonly used anaesthetic with rapid recovery and less side effects and total intravenous anaesthesia (TIVA) with propofol is a common technique now. The reduction on certain serum pro- inflammatory cytokines may lead to more smooth post- surgical recovery. Recent case report proved the analgesic effect of propofol infusion. However other animal and clinical studies showed controversial result. The aim of this retrospective study is to investigate the postoperative analgesic effects and side effects of intraoperative TIVA with propofol in patient undergoing surgery at Queen Mary Hospital, Hong Kong between 2014 to 2016.
Propofol is one of the most commonly used intravenous anaesthetic drugs both for induction and maintenance of general anaesthesia. Some of the advantages of total intravenous anaesthesia (TIVA) with propofol include reduced nausea and vomiting, reduced atmospheric pollution, better wake up profile and a more favourable intracranial physiology. However, the need for a reliable intravenous access, specialized pumps, pain on injection and potential concerns regarding awareness are some reasons that preclude more common use. Postoperative dental pain produces an inflammatory pain model. Since propofol has anti-inflammatory effects, it may have significant analgesic effects in patients undergoing dental surgery. To the best of our knowledge, there are no randomized controlled trials comparing the effects of TIVA propofol and inhalational anaesthetic on postoperative dental pain. The aim of this study is to investigate the effect of TIVA propofol on postoperative pain scores, analgesic consumption, and adverse effects in patients undergoing dental surgery. This will help determine whether propofol may be a useful analgesic adjunct in dental surgery.
It is difficult to assess pain and agitation in the NICU population because for a multitude of reasons including the pre-verbal nature of the patient population, the atypical pain response of premature infants, and the use of muscle relaxing medications that exclude motor response in pain assessments. Current assessment tools are based on physical exam and vital signs. The investigators propose to study the role of EEG and palmar conductance (PD) as additional tools in the assessment of pain and agitation
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.
Patients are randomized into 2 groups. The intervention group which receives preoperative counseling about pain and a control group which does not receive this counseling. The patients are followed up looking at pain scores and pain experience and satisfaction with pain management for 2 days post operative.
Both Ultrasound guided Adductor Canal Block ( ACB) and Femoral Nerve Block (FNB) has been used to provide postoperative analgesia for knee surgeries. To the investigators' knowledge, no comparison has been made between those blocks in relation to postoperative quadriceps muscle strength, or duration and quality of postoperative analgesia for arthroscopic ACL reconstruction in pediatrics. If ACB provides postoperative analgesia after arthroscopic knee surgery comparable to FNB, it has the potential to improve the postoperative outcome as it will lead to less quadriceps muscle weakness and early mobilization, both of which are very important in the early postoperative period.
The purpose of this randomized controlled trial is to determine whether, "ICE-T," a novel multimodal postoperative pain regimen composed of around the clock ice packs, toradol, and tylenol, has improved pain control intake compared to the standard postoperative pain regimen in patients undergoing vaginal pelvic floor reconstructive surgery.
The surgical interventions for treating morbid obesity, i.e. bypass procedure and sleeve gastrectomy are collectively covered under the term `bariatric surgery`. The growth of bariatric surgery has seen consonant development of anaesthesia techniques so as to ensure patient safety and facilitate post-surgery outcome. Conventionally, balanced general anaesthesia techniques routinely use opioids peri-operatively for intra-operative haemodynamic homeostasis and postoperative pain relief. However, since the morbidly obese patients have high prevalence of obstructive sleep apnea(OSA) and other co-morbidities the same technique when employed in the morbidly obese patients hampers early and intermediate postoperative recovery due to the occurrence of side effects, such as, sedation, PONV, respiratory depression, depressed GI-mobility. The above stated side effects, have lead to increased propensity for postoperative cardiac and pulmonary complications. Obese patients are more vulnerable and sensitive to the narcotics and sedatives, these drugs need to be employed judiciously in these patients. On the other hand, the reduction in opioid use may result in acute post-operative pain that may limit post-surgery rehabilitation. Therefore, we need to minimise opioid use and employ some other drugs which besides having analgesia, has a opioid-sparing effect also. Ketamine, an N-methyl-D-aspartate (NMDA) receptor antagonist, has analgesic properties in sub-anaesthetic doses. When used in low dose (0.2mg/kg), it is an analgesic, anti-hyperalgesic, and prevents development of opioid tolerance. On a conceptual basis, a key advantage of ketamine is that it can reduces post-operative pain and use of opioid when used per-operatively. Therefore, a regimen which avoid or minimise use of opioid is likely to decrease opioid-related postoperative morbidity in these patients undergoing bariatric surgery.In view of the above, a clinical research is highly desirable to study techniques to decrease the use of opioids in obese surgical patients.This prospective randomised two-arm study aims to assess the effect of low-dose ketamine on postoperative pain relief and opioid-sparing ability in obese patients undergoing bariatric surgery.
