Filter by:The purpose of this study is to evaluate whether pre-emptive local bupivacaine injection is a better alternative pain control modality than the conventional intravenous patient controlled analgesia.
The purpose of this study is to find a more accurate postoperative pain assessment for teenager patients. This is important because a patient should not have a very strong pain medication such as morphine if the pain is just mild.
The purpose of this trial is to investigate the efficacy and safety of lidocaine 5% medicated plaster in localized chronic post-operative neuropathic pain in comparison to placebo plaster.
The purpose of this study is to determine wether wound infiltration brings additional analgesia effect after cesarean section with optimal standard postoperative analgesia
"This study is a single-center, randomized, open-label, 3-period, 5-treatment, 6-sequence design. A total of 54 eligible subjects will receive three total treatments; one with intravenous (IV) infusion and two with the Study System. Each subject will be randomly assigned to receive a treatment sequence consisting of Treatment A (IV fentanyl citrate), Study System Treatment B (170 mcAmp), and one of three additional Study System treatments (140 mcAmp or 200 mcAmp or 230 mcAmp) "
Object: Every person's pain perception and possible postoperative pain is different. As the investigators know, they are affected by many factors. However, the investigators don't know whether the smoking factors, alcohol factors, surgery type, education background, etc. will affect individual pain perception and possible postoperative pain in Chinese population. This study was conducted to investigate the power of these possible affect factors. Method: Patients receiving elective surgery under general anesthesia were recruited into this study. The investigators measured their preoperative pressure pain threshold (PPT) and pressure pain tolerance (PTO)and also investigated the patient's personal information of smoking factors, alcohol factors, surgery type, education background, etc. In addition, we retrospectively investigated the visual analog scale (VAS) during patient-controlled analgesia (PCA) treatment 0 to 48 h after operation as well as the PCA press frequency and drug consumption of those patients who received PCA administration.
The purpose of this study is to show the effectiveness of COV155 compared to placebo in subjects with acute moderate to severe pain following bunionectomy surgery.
A Prospective double-blinded randomized clinical trial to test the effect of transversus abdominis plane block on postoperative pain and opoid consumption after abdominal hysterectomy. Two groups of each 24 patients. All patients are given general anesthesia. The patients are randomized to have a ultrasound guided bilateral transversus abdominis plane block with either 2 x 20 ml 0,75 % ropivacaine or 2 x 20 ml of 0,9 saline. All patients are provided with a PCA for self administration of morphine. Pain score on visual analog scale, nausea and vomiting are monitored at 1, 2, 4, 6, 8 and 24 hours postoperatively as well as the total consumption of morphine after 24 hours.
Pelvic organ prolapse is an herniation process, needing a mesh reconstruction for long lasting therapeutic effect. Yet, mesh implants were reported to be related to severe adverse effects. This study looks at the potential benefit of mesh size reduction regarding avoiding operative complications.
Pain following abdominal surgery is managed with the use of thoracic epidural analgesia (TEA) where the epidural is inserted in the spine at the level of scapula The risks due to TEA include difficulty with insertion, failure in up to 40% of patient in the perioperative period, fall in blood pressure and a rare devastating complication of paralysis either due to bleeding or infection. Injury to spinal cord is also a feared complication. Therefore alternative techniques need to be evaluated. Paravertebral block (PVB) has been documented to provide pain relief following abdominal surgery using an earlier technique which posed the risk of puncture of the covering to the lung (pleura) resulting in pneumothorax. The current technique involves the use of curled catheters inserted using ultrasonography to lie outside the pleura where the nerves travel thus reducing the chances of pneumothorax and catheter migration. Objective of the current study is to compare the efficacy and safety of bilateral PVB with TEA. Patients undergoing bowel surgery will be randomized to receive thoracic epidural analgesia or bilateral thoracic paravertebral blocks. Pain scores during rest and coughing, failure and complication rates will be compared between the two groups. Objective: The objective of the investigators is to determine whether ultrasound (US)-guided bilateral thoracic paravertebral blocks (PVB) using curled catheter provides effective post-operative analgesia as compared to thoracic epidural analgesia in patients undergoing open abdominal bowel surgeries. The primary outcome of this study will be the pain scores over the first 24 hours following open bowel surgeries. Secondary outcomes include 1. Analgesic consumption in the perioperative period, 2. Block related data (block performance time, success rate, extent of sensory block, complications) 3. Hemodynamic parameter every 6 hourly 4. Incidence of side effects like nausea and pruritus scores, time to return of bowel activity Hypothesis Null Hypothesis: Primary. Paravertebral blocks provide equal analgesia in the early postoperative period (first 24 hours of surgery) as compared to thoracic epidural analgesia in patients undergoing bowel surgeries by laparotomy. Secondary 1. The analgesic consumption between PVB and TEA is not different during the first 24 hours following surgery 2. The block performance time, success rate and extent of sensory block with PVB are not different from that of TEA. 3. Side effects and complications following bilateral PVB are not different from those occurring after TEA
