A study investigating the pharmacokinetic profiles of four extended release paracetamol formulations
This is an open-label (both the physician and healthy volunteer know which medication will be administered), single-dose, 5-dosing period study to characterize the pharmacokinetics (process by which oxycodone is absorbed, distributed, metabolized, and eliminated by the body) and the effects of food on the pharmacokinetics of oxycodone. The study will take place over approximately two and a half months and will consist of three phases: a screening visit to determine eligibility for the study, a 5-dosing period treatment phase, and an end-of-study visit.
An alternative to general anesthesia - which puts a patient completely to sleep - is regional anesthesia, where local anesthetic is injected under the skin to freeze or 'block' a nerve or set of nerves. This method allows a patient to be awake during surgery and avoids any unpleasant after-effects of general anesthetic. A regional block is normally performed by inserting a needle under the skin so that the needle tip is near the nerve to be blocked, followed by injection of a single shot of enough local anesthetic to block any sensation that the nerve normally provides. Although regional nerve blocks provide pain relief during a surgical procedure, they eventually wear off, occasionally leaving the patient to contend with localized pain in the part of the body that was operated on. In these cases, over-the-counter painkillers like Tylenol or Advil may not be strong enough to completely take away the pain. We believe that, instead of giving a single shot of anesthetic, patients can be fitted with a catheter - a thin, flexible tube - that can be used to deliver one dose of local anesthetic to block the nerve before surgery and which could also be used to deliver a second dose of anesthetic just prior to discharge from the hospital. This way, the patient still only receives one needle poke, but their pain can be better managed following surgery. Our study will compare the post-nerve block pain profiles of individuals who have received a single-shot injection of local anesthetic versus those who have received two doses via the catheter delivery method.
Sick or premature neonates are exposed to frequent painful and stressful procedures during their stay in neonatal intensive care units. Although neonates do feel pain and may have long term effects induced by painful experiences, prevention and treatment of neonatal pain is far from optimal in many units. An epidemiological study (EPIPPAIN) conducted in neonatal and pediatric intensive care units in France in 2005 showed that painful procedures were extremely frequent and that analgesics treatments varied a lot among units. Since many guidelines have been issued by international scientific societies to manage neonatal pain, one may expect that the prevention and treatment of neonatal pain has improved over the last 6 years. Although awake endotracheal intubations are extremely difficult or impossible in older children or adults, such intubations are still frequently performed without sedation/analgesia in neonates. Recent studies have shown that premedications facilitate intubation conditions and greatly improve neonates tolerance of the procedure. Studies aimed at assessing the risks and benefits of different sedations/analgesia strategies are urgently needed in neonates. We also need a tool to assess at the same time the technical conditions of intubations and the tolerance of the neonate to the procedure so that data from different studies can be compared. The objectives of the present study are: 1. To describe the incidence of painful and stressful procedures performed in the neonate in intensive care units as well as in neonates transported by the medical emergency system (SMUR) of the Ile-de-France region 6 years after the first EPPIPAIN study conducted in the same region and same type of population in order to assess the evolution of practices. The description of painful and stressful procedures will be completed with a real-time around-the-clock assessment of the pain induced by procedures using a validated behavioral pain scale. 2. To link this study with The Epipage study 2 in order to look for associations between the number of painful and stressful procedures and/or analgesic treatments of the neonatal period and the neurological outcome of children that will be followed in the Epipage cohort. The Epipage study is a separate study that will follow for 13 years a cohort of premature neonates recruited in 2011. 3. To describe the incidence of painful or stressful procedures and analgesic treatments in neonates transported by the pediatric emergency system (SMUR) of the Ile-de-France region in France. 4. To obtain initial validity of a tool permitting to assess intubations in neonates. An observational detailed description of endotracheal intubations conditions will be conducted in neonates transported and intubated by SMUR and in neonates intubated in intensive care units 5. To describe continuous sedation and analgesia practices in ventilated neonates in intensive care units. For these neonates, data from medical records will be recovered up to 2 months of admission in intensive care units 6. To describe the frequency of heel sticks for glycemia measurement and blood gazes practices among centers. Relate heel stick practices to the normality or abnormality of glycemia results
This study is a post-marketing surveillance to monitor safety and efficacy of remifentanil during various surgeries and identify SAEs, adverse drug reactions, and unexpected AEs not described as precautions or warnings and to identify prognostic factors that have an effect on the AEs and to assess effectiveness of remifentanil in real clinical practices after marketing. The subjects are patients prescribed for remifentanil by the investigators at the sites based on prescription information in normal clinical practices.
Pain control after hip replacement surgery is important to ensure patient comfort, allow mobilisation, and aid recovery. The investigators propose a simple and pragmatic study comparing two different anaesthetic techniques in the provision of pain relief after hip surgery. Patients will be randomised to receive either spinal anaesthesia containing morphine or spinal anaesthesia without morphine and an ultrasound guided fascia iliaca nerve block. Although morphine is an effective pain killer, its side effects include itch, urinary retention, nausea and potentially fatal breathing problems. If the nerve block can be shown to provide comparable pain relief to spinal morphine, then morphine could be removed from the spinal injection. This could reduce side effects and improve patient safety. The investigators wish to investigate whether ultrasound guided fascia iliaca plane block provides analgesia which is comparable to that of intrathecal opioid for primary hip arthroplasty in the first 24 hours after hip replacement surgery
Objectives: Sleep characteristics have been used for prediction of neuro-developmental outcome. The aim of our study was to evaluate the influence of morphine and midazolam on the development of SWC in newborns > 32 weeks' gestational age after major non-cardiac surgery. Study design: This prospective aEEG study included infants > 32+0 weeks' gestation admitted to the Neonatal Intensive Care Unit at The Royal Children's Hospital in Melbourne who were undergoing major non-cardiac surgery. The BrainZ Monitor (BRM2, Version 8.0, BrainZ Instruments, New Zealand) was applied post-operatively. The time of onset and quality of SWC and the maximum levels of morphine and midazolam as predictors of time to SWC were then assessed. Results: Forty-seven eligible infants were included. Emergence of SWC was observed at a mean of 13 hours post-surgery. The maximum dose of morphine or midazolam was not predictive of time to SWC. Conclusions: Despite high doses of continuous infusions of morphine and midazolam SWC was observed on aEEG in neonates > 32 weeks' gestational age soon after major non-cardiac surgery. The main type of aEEG background pattern was not affected by the maximum dose of either morphine or midazolam. Abnormalities in aEEG in post-surgical patients are not always drug related.
Inadequate pain control after abdominal procedures may lead to adverse postoperative outcome. Epidural analgesia is currently an accepted technique in abdominal surgery, but its use has been limited in liver resections by postoperative coagulation disturbances and the possible increased risk of bleeding complications, including spinal hematoma. A range of alternative analgesic techniques can be used for major liver or pancreatic resections, including intrathecal morphine (single shot) administered immediately before surgery, and continuous administration of intravenous (IV) short-acting opioids, such as remifentanil, plus a single bolus of IV morphine. Postoperatively analgesia may be obtained by patient-controlled morphine analgesia (IV PCA). Both protocols have been demonstrated to provide satisfactory postoperative pain relief, and each has its unique advantages. However, to this end there is no data in the literature to show benefit from one regimen over the other. We therefore wish to determine whether there is a difference in analgesic efficacy between the two techniques, as optimizing perioperative pain relief in this rapidly expanding surgical field is of utmost importance. Our hypothesis is that continuous intraoperative IV analgesia with remifentanil followed by IV PCA morphine is not inferior to intrathecal morphine with respect to analgesia and ambulation outcome, and may provide an alternative, non-invasive intraoperative analgesic technique.
Presently, the literature addressing the relationship between epidural analgesia and likelihood of breast-feeding is inconclusive. Numerous studies have found that epidurals, administered prior to vaginal delivery of a full-term, healthy neonate, significantly decrease lactation success at follow-up times ranging from 24 hours to 6 months postpartum. One proposed mechanism is that analgesics, by decreasing maternal pain during labor, decrease maternal endorphin production and result in the transmission of lower endorphin levels to the neonate during breast-feeding. Lower endorphin levels, in turn, may render the neonate less likely to suckle optimally. Other studies have found that epidural analgesia does not significantly decrease lactation success when used during the vaginal delivery of a full-term, healthy neonate. Although most studies to date have compared the breast-feeding success of epidural recipients and non-recipients at various points postpartum, they do not specifically note whether deficient feeding behaviors on the part of the infant contribute to failed breast-feeding. The present study uses the LATCH assessment tool to score the infant's ability to latch onto the breast and the presence of audible swallowing, as well as the mother's level of physical comfort with breast feeding, whether she can successfully position the infant for feeding on her own, and whether her nipples are inverted, everted, or flat. Thus, the LATCH assessment enables the separation of multiple factors that may contribute to breast-feeding failure. A multivariate regression analysis will determine how strongly the probability of breast-feeding at hospital discharge correlates with epidural duration, LATCH scores, and beta-endorphin concentrations in colostrum.
