Filter by:A sufficient analgesia in injured or sick people is the main goal of physicians treating a patient. In emergency medicine potent analgesia like ketamine or opioids are routinely used. It is unknown if there are any severe side effects or if the use is safe while in use in a Helicopter Emergency Service equipped with emergency physicians.
Dexmedetomidine（DEX）is a potent and highly selective α 2 adrenergic receptor agonist. It has the pharmacological effects of sedation, hypnosis, analgesia, anti-sympathetic and neuroprotective. Its sedative effect is similar to normal sleep, and easy to wake up. DEX is widely used clinically because of its advantages and acceptable side effects. The best clinical use of DEX is uncertain, including intravenous, intramuscular, oral, intralnasal and sublingual administration. Its clinical recommended use is intravenous load infusion for more than 10 minutes, followed by continuous infusion. However, the clinical recommended usage is inconvenient, time-consuming and other shortcomings, for the growing popularity of daytime surgery, will inevitably affect the operation process and turnover. If a suitable dose range of DEX can be found for a single intravenous injection to achieve clinical efficacy quickly without significant hemodynamic effects, this will improve the patient's postoperative recovery. We will speed up the utilization and turnover of medical resources. The aim of this study was to investigate the optimal dosage of DEX for single intravenous injection.
If the individual patient's pain is assessed and the amount of analgesic needed after surgery is predicted, appropriate injection of pain control and excessive injection of narcotic analgesic can be prevented. Therefore, investigators try to evaluate the degree of pain during surgery and the amount of analgesic use for management of postoperative pain.
The relationship between the target effect site concentration of remifentanil and the pupil diameter and reactivity in response to a standard noxious stimulus in cardiac surgery during extra corporeal circulation will be evaluated.
The objective of this trial is to determine whether an opioid-free general anesthetic (OFA) technique utilizing ketamine, dexmedetomidine, lidocaine, and gabapentin can help reduce postoperative respiratory depression in the post-anesthesia care unit and ward in children with sleep-disordered breathing undergoing tonsillectomy when compared with traditional opioid-containing techniques. It is expected that this OFA regimen will have a measurable reduction on postoperative respiratory depression in children with sleep-disordered breathing.
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.
Half of the people over the age of 65 are not functioning at their optimal level because of interference from pain. > 50% of older adults had taken prescriptions of pain medication beyond a 6-month period. In Emergency Department 80% of visits involving conditions with painful component. The study aims to observe and check side effects of most frequently pain killers prescribing at home to patients over 65 years old after a visit in emergency department.
A single center trial to evaluate the efficacy, tolerance, and acceptability of Oxygenated Glycerol Triesters (OGT) mentholated cream on acute musculoskeletal pain in normal healthy adult volunteers suffering from a recent inflammation of muscles and joints. Patient who met eligibility requirements were instructed to identify one area on their body where they were experiencing the most acute musculoskeletal pain/discomfort. Patients were provided with visual analog scales in order to quantify their pain. Patients either received mentholated cream with or without OGT and instructed to rub on the identified site 3 times a day for 7 days. Pain and other observations were written in a diary for each day.
The purpose of this repeated dose study is to develop recommended dosing information for initiation of therapy with OROS Hydromorphone in patients with chronic non-malignant pain converting from other strong oral or transdermal opioids. It will also assist in the development of a recommended starting dose by which patients can be titrated to an appropriate maintenance dose of OROS Hydromorphone HCI. The safety profile for OROS Hydromorphone HCI will also be evaluated.
The purpose of this study is to compare several analgesics given in approved daily doses in combination with a daily cardioprotective dose of aspirin (81 mg), to study their bleeding properties and their effects on the stomach in healthy volunteers.
