Filter by:This was a single centre, randomised, double blind, placebo controlled, two-way cross-over design study to assess the feasibility of pain PD tests and to determine the variability and effects of a known analgesic drug (the opioid remifentanil) in South Korean healthy volunteers.
The main objective of this study is to establish the postoperative "pain pathways" observed from D1 to D7 in the context of the current management after orthopedic, digestive, obstetrics and gynecology, urology, neurosurgery, vascular and thoracicn surgeries.
Double J (DJ) stents are placed following upper urinary tract surgeries. DJ stents are usually removed under local anesthesia using rigid cystoscope. Patients experience a lot of pain during this procedure and also continue to have discomfort during voiding for few days. The use of lignocaine jelly during this procedure is not very effective. Use of diclofenac suppository during flexible cystoscopy has been proven to be effective. This study was done to assess the effect of oral diclofenac in pain relief in patients undergoing DJ stent removal by rigid cystoscopy when compared to placebo and to assess its safety in these patients
This study evaluates the role of microneedle pretreatment in the speed at which anesthesia develops after application of topical 4% lidocaine.
A standardized tetanic stimulation is applied to patients under propofol-remifentanil TCI, in a cross-over fashion, at two different levels of anesthesia monitored by the BIS: BIS 25 and BIS 55. Remifentanil target remains constant during the whole study period (1 ng/ml). Pupillary reflex dilation is recorded after each stimulation.
This will be a randomized, controlled, parallel-group clinical trial. The aim of this studio will be to evaluate the effectiveness of "Hands/Eyes/mouth" behavior management technique versus a conventional technique (covering the patient´s vision) during an inferior alveolar and lingual nerve block in preschool children referred for treatment at the School of Dentistry, Cardenal Herrera CEU University (Valencia, Spain). The sample will consist of 52 children from 3 years old to 5 years 11 months old who need dental pulp treatment and/or tooth extraction of primary molars. Preschool children with no history of allergies to Lidocaine or systemic/neurological diseases and who did not take local anesthesia before the study will be include in this research.
Compared to early postpartum (10-15 weeks) observations, paracetamol clearance was significantly higher (21.1 vs 11.7 l.h-1, + 80 %) at delivery. This higher clearance was due to a disproportional increase in glucuronidation (11.6 vs 4.76 l.h-1, + 144 %), a proportional increase in oxidation clearance (4.95 vs 2.77 l.h-1, 78 %) and primary renal clearance (1.15 vs 0.75 l.h-1, 53 %) [KUlo et al, Int J Obstet Anesth]. This increase in glucuronidation clearance may in part be driven by oestradiol, and may explain within and between individual differences in paracetamol metabolism (e.g. oral contraceptives, follicular vs luteal phase, postpartum, pregnancy, or duration of pregnancy) in young women. Based on a pooled analysis, investigators aimed to further explore the impact of these covariates on paracetamol metabolism based on plasma and urine collections in women at delivery, in postpartum (early, or late) and healthy volunteers, either or not on oral contraceptives (OC) following intravenous (iv) paracetamol administration.
Anesthesiology daily practice consists in management of sedation, immobility and analgesia. The monitoring of this last component remains largely based on indirect signs with poor sensitivity and specificity such as heart rate and blood pressure. Accordingly, there is an increased demand for more accurate analgesia monitors. Several parameters have been studied in the recent years such as spectral entropy, skin conductance, pupillometry or heart rate variability (HRV). The HRV is influenced by the balance of sympathetic and parasympathetic tones, and is therefore influenced by pain and analgesia. MDoloris Medical Systems SAS, located in Lille, France, had developed a monitor called PhysioDoloris (TM) that uses an analysis of the HRV to generate a clinically useable index, the Analgesia-Nociception Index (ANI). The ANI varies from 0 to 100, a lower number indicating less parasympathetic tone. It has been shown in previous studies under general anesthesia to decrease at the moment of surgical incision and pneumoperitoneum inflation and to increase with opioids administration. The purpose of this study is to show a correlation between the variation of the ANI with pain scores in awake healthy volunteers who are subjected to standardized painful stimuli of increasing intensity. The investigators hypothesize that an increasing pain score will correlate with decreasing ANI values.
Ethyl chloride vapocoolant sprays provide transient skin anesthesia within seconds of application. The current investigation aim is to compare the effect of ethyl chloride based vapocoolant spray to placebo in reducing pain associated with arterial puncture for gasometry determinations. The investigators will conduce a double-blind randomized placebo-controlled trial at Emergency Department. We will enroll patients who come to Emergency Department who need an arterial gasometry determination. Patients will be randomized to intervention-group (ethyl chloride vapocoolant sprays will be usad before arterial puncture) or to placebo-group (alcohol spray as placebo will be used before arterial puncture.) and after the puncture they will rate their pain using a 10 points visual analogue scale.
Reports have been appearing in literature over the past years of various nociception-antinociception monitors, introduced and promoted from major manufactures. Recently a new term Practice misalignment" has been recently coined indicating research study groups that are distant from daily anesthesia practice, with some scientific relevance but very little clinical relevance simulating "purely hypothetical" conditions that are not related to "everyday" anesthesia practice.
