Filter by:The purpose of this exploratory study is to characterize the postoperative pain profile of patients undergoing operation with internal fixation of an ankle fracture under nerve block anaesthesia. Special attention is payed towards the possible existence and clinical relevance of a rebound pain phenomenon upon cessation of the nerve block. Results are used to guide the set up of a randomized controlled trial on the subject.
the aim of this study was to investigate compare the effect of peroperative intravenous single dose dexamethasone and the addition of dexamethasone to femoral nerve block on postoperative analgesic consumption and patient comfort in unilateral total knee arthroplasty patients
Patients with a daily use of opioids may develop higher postoperative pain levels, often need high doses of morphine and therefore their pain may be difficult to treat. A low dose of an old anesthetic drug, ketamine, administered during surgery can possibly reduce pain and morphine consumption in these patients. Our purpose is to investigate the effect of low dose ketamine on morphine consumption and pain after spine surgery in patients with a daily use of opioids. Our hypothesis is that low dose ketamine can reduce morphine consumption, pain and side-effects after spine surgery.
The purpose of this study is to evaluate the efficacy and safety of MDT-10013 in men and women 18 to 80 years of age who are undergoing bunionectomy. The primary objective is to determine the analgesic efficacy of MDT-10013 compared with standard of care in the treatment of acute postoperative pain after subjects undergo bunionectomy.
In this randomized, controlled, observer-blinded study we plan to evaluate pain relief after ultrasound-guided transversus abdominis plane (TAP) block using bupivacaine and wound infiltration using liposomal bupivacaine in patients undergoing abdominal hysterectomy.
The study comprises of a series of pupillary measurements using infrared pupillometry in patients undergoing arthroscopic knee surgery of any type. Infrared pupillometry will be used to assess whether a painful stimulus results in pupillary reflex dilation (PRD). The extend of the PRD may be an indicator how painful a stimulus is. This may help to predict the amount of discomfort a patient will be experiencing after emergence from general anesthesia. In addition to measuring the pupillary reflex dilation, we will also measure oscillations of pupil size before and after indiction of anesthesia, as well as during recovery. These spontaneously occuring oscillations in pupil size, also called hippus, appear to be sensitive to anesthetics and opioids. However, the effect of these drugs on hippus has not been systematically addressed. The aim of the study is 1. to identify whether regional anesthesia techniques such as femoral and sciatic nerve blocks will block the PRD. This would allow assessment of block success in the anesthetized patient. 2. to correlate the extent of the pupillary reflex dilation and hippus in the anesthetized patient during and at the end of surgery with early postoperative pain scores and subsequent analgesia requirements. Such correlation would allow to predict the amount of postoperative pain before the patients emerge from general anesthesia.
The purpose of this study is to determine that periarticular levobupivacaine infiltration after surgical fixation of fractured neck of femur will improve the early postoperative pain sensation.
Evaluation of the combination of lateral femoral cutaneous nerve "single shot" and femoral nerve "single shot" block as effective and safe alternative postoperative analgesic technique after hip replacement surgery.
The Quadratus Lumborum (QL) Block is an ultrasound-guided technique described by Rafael Blanco in 2007. The nerves to the lower abdominal wall can be anesthetized by injecting local anesthetics close to the anterior border of the quadratus lumborum muscle. In our randomized, controlled, double-blinded study ultrasound-guided QL-blocks in 20 female patients after cesarean delivery will be compared with a placebo control group of 20 patients to investigate analgesic consumption, pain level, opioid related side effects and mobilization.
Treatment of postoperative pain with hydromorphone (a strong analgesic) using patient-controlled analgesia with target concentrations in blood compared to conventional patient-controlled analgesia after planed cardiac surgery
