Filter by:This is a single-center, prospective, randomized, controlled study of the appliedVR RelieVRx headset in subjects undergoing Total Knee Arthroplasty (TKA). This study will evaluate two primary endpoints - effectiveness of a single use of RelieVRx in the reduction of acute postoperative pain by 20%; and overall effectiveness of RelieVRx as an opioid-sparing intervention, where opioid consumption is reduced by at least 20% over a 90-day postoperative period in the interventional, standard of care (SOC) plus RelieVRx group compared to the control, SOC group.
The investigators will examine and analyze opioid narcotic usage patterns by requesting patients keep a two week log of their opioid usage following outpatient hand surgery with a standard analgesic regimen consisting of an opioid, NSAID, and acetaminophen. Following a pre-intervention period, the investigators will add scopolamine to the regimen and have patients monitor their opioid consumption. The investigators will then compare opioid consumption patterns following completion of the study.
The main objective of the pilot study is to investigate the process that includes recruitment (to estimate the rate of enrollment), feasibility, protocol refinement, and willingness of the subject to be randomized. To provide a sample estimate of the population parameter which is the true value in the target population to be used in the planning of a larger confirmatory study. Secondary objectives include: To examine the efficacy of pre/post-operational administration of dexamethasone vs Vicodin (acetaminophen and hydrocodone) for post-operative pain control following periodontal surgery at the Henry M. Goldman School of Dental Medicine. To examine how BMI alters the response to dexamethasone and hydrocodone following periodontal surgery since obese patients have shown higher pain scores and increased pain sensitivity in previous experimental models of pain.
This multiple ascending dose study assesses the safety, tolerability and pharmacokinetics of NP10679 when delivered intravenously in escalating dose levels in comparison to placebo.
The study aims to determine the tolerability of repeated doses of Maxigesic® IV over an extended period of exposure.
Magnesium sulfate has been shown to be useful in many situations in medicine, such as eclampsia prevention and treatment, pulmonary hypertension, arterial pressure, asthma, cardiac arrhythmias and pheochromocytoma. Recently there has been a growing a big interest in this drug as an useful adjuvant in anesthesia, with analgesic and anesthetic sparing effect, antihyperalgesic property and potentialization of the neuromuscular blocker agent effect. On the other hand there has been a growing concern related to opioid administration, such as hyperalgesia, delayed return of intestinal function and the (still controversial) possibility of facilitating effect on tumor growth and metastases in cancer patients. This project is based on a previous randomized, double blind prospective trial (conducted by one of these authors and not yet published) comparing two groups of patients who received general intravenous total anesthesia with propofol in controlled target infusion. The surgical stress index is obtained by the interaction between the interval between heart beats and the amplitude of the photoplethysmography wave, whose algorithm generates a number related to the hemodynamic result of the increase of the sympathetic tone, which has shown to be the most sensitive resource in detecting the imbalance between the stimulus nociceptive and anti-nociception.
Intense e recurrent nociceptive stimulation, which occurs in the postoperatively, can trigger sensitization of the peripheral and central nociceptive pathway, leading to chronic pain. Patients with rotator cuff injury often present to surgery due to referred moderate to intense long-term pain. During the immediate postoperative period, pain is rare due to the routine administration of a brachial plexus blockade as an adjuvant to improve the quality of postoperative analgesia. However, after the second postoperative day, the effect of the blockade ceases, and the pain becomes high and hard to treat, leading the patient to request administration of more frequent and more potent analgesics. The aim of this project is to assess the postoperative analgesic benefits of a brachial plexus blockcade 2 days before arthroscopic surgical correction of rotator cuff injury by reducing the sensitization of the nociceptive pathway.
Quadratus lumborum block is a newly developed block with good performance in lower abdominal surgery. In a cadaveric study, the spread of local anesthetic in the anterior approach of QL block (QL3) was reported to cover nerve roots from T10 to L3. Thus, it was hypothesized that this approach could be used in hip surgeries with minimal motor affection. This study aims to compare QL3 block and suprainguinal Fascia Iliaca block in the duration of postoperative analgesia, pain scores, motor power in quadriceps muscle, and side effects.
ESP block advantages include its simplicity, easy identifiable ultrasonographic landmarks and low risk for serious complications as injection is into tissue plane that is distant from pleura, major blood vessels and discrete nerves. Coupled with the fact that the erector spinae muscle and ESP extend down to the lumbar spine, ESP block was hypothesized to be performed at the level of L4. In a recent case report, ultrasound guided ESP block was successfully performed at L4 transverse process level for postoperative analgesia after total hip arthroplasty. However, confirmation of the efficacy of ESP block in hip replacement surgeries needed more investigation.
Magnesium sulfate has been applied in various situations due to actual or potential benefits related to neuroprotection, treatment of eclampsia/pre-eclampsia, arterial hypertension, adrenergic reflex under laryngoscopy/intubation and, shivering, nausea and vomiting, among others. In anesthesia it has been useful as an analgesic adjuvant; however, the method to calculate the dose of magnesium sulfate in obese population is unclear. The objective of this project is to compare two methods of dose calculation based either on the real weight or corrected ideal weight.
