Filter by:the primary objective of this study is to assess and compare the efficacy, safety and benefits of Controlled Release (CR) oxycodone/paracetamol with our current pain protocol (paracetamol/naproxen) in the treatment of acute postoperative pain at home after painful day-case surgery. We hypothesize that ambulatory patients postoperatively treated with oxycodone/paracetamol will achieve better pain relief with equal side effects compared to patients treated with paracetamol/naproxen. Our second goal is to assess analgesic adherence in the outpatient setting. Endpoints: Primary endpoints: pain intensity (Visual analogue scale) Secondary endpoints: - side-effects/ adverse effects of study medication - patient satisfaction with pain treatment - compliance to study medication Study design: Patients scheduled for painful ambulatory surgery (knee arthroscopy, unilateral open or laparoscopic inguinal hernia repair) will be enrolled in an open randomized controlled trial (RCT) at our pre-assessment clinic. Subjects will be enrolled by a study nurse and will be randomized into one of three study treatment groups using a computer-generated list. Patients in group 1 (PCM/NAPR) are assigned to postoperative analgesia using naproxen 500 mg orally twice a day for 48 hours postoperatively. Patients assigned to group 2 (PCM/Oxy1) receive CR oxycodone 10 mg orally twice a day for 24 hours. Patients in group 3 (PCM/Oxy2) are postoperatively treated witch CR oxycodone 10 mg orally twice a day for 48 hours. All patients also receive paracetamol 1000 mg orally four times a day for 48 hours postoperatively. Recovery after discharge will be assessed using a diary for up to 48 hours after surgery. Three times a day, patients have to rate pain at rest and movement (VAS), fatigue, nausea, vomiting, pruritus, miction problems, pyrosis, and abdominal complaints. Furthermore, compliance to the use of the study medication will be assessed by checking whether the patients took the study medication as prescribed and if any other pain medication was used. Compliance will be assessed three times a day and patients will be divided into three groups according to medication use: always = full compliance, sometimes = partial compliance, or never = no compliance. Finally, overall satisfaction with the postoperative pain treatment will be assessed (score 0-10).
Aim of this study is to compare benefits and disadvantages in using continuous infusion of morphine or fentanyl for post operative analgesia.
Fentanyl is a potent opioid, it is theoretically 100 times more potent that morphine and in severe acute postoperative pain acts faster than its congener (morphine ) for pain relief . In the literature there is no study that corroborates this theoretical assumption and proposes to compare which has fewer adverse effects. This drug produces effects similar to those reported for morphine but less magnitude and has the advantage that during the postoperative period respiratory depression, antitussive effect , gastrointestinal discomfort and physical dependence are manifested in a significantly less degree. Trying to solve the management of postoperative pain relief , our objective is to determine by controlled clinical trial of superiority if in adult patients undergoing surgery , fentanyl reduces faster qualification time of severe pain to mild pain in the postanesthesia care unit compared to morphine.
Fluctuations of female sex hormones during the menstrual cycle influence pain perception. Endogenous pain is pronounced in the follicular phase of the menstrual cycle. The investigators tested the primary hypothesis that the women having surgery during their follicular phase have more acute pain and require more opioids than those in the luteal phase, and secondarily the investigators tested that women who have surgery during their follicular phase have more incisional pain at 3 month postoperatively.
The purpose of this study is to learn how well Liposomal Bupivacaine (Exparel™) controls post-operative pain in patients undergoing both open and laparoscopic (minimally invasive) abdominal hernia repair surgery.
The purpose of the study is to determine the minimum effective concentration of bupivacaine (EC50) in femoral block for analgesia by ultrasound after knee surgery.
This study is designed to evaluate lung function and pain control of continuous supraclavicular versus suprascapular versus interscalene nerve catheters in subjects undergoing total shoulder replacement. The investigators hypothesize that all three groups would have similar pain control; the supraclavicular and suprascapular groups may have better lung function.
Total knee prosthetic replacement causes severe postoperative pain. Various analgesic techniques have been used in pain control. Comparison of epidural and femoral nerve block is lacking, furthermore effect on chronic pain is unclear. The investigators aimed to compare the effects of epidural and femoral block on acute and chronic postoperative pain.
The aim of this study is to evaluate the effect of the ultrasound guided rectus sheath block (RSB) on both intraoperative sevoflurane consumption and postoperative analgesia.
The purpose of this study is to assess the efficacy of the intraoperative injection of prolonged acting (liposomal) bupivacaine in postoperative pain control after truncal surgical incisions.
