Filter by:A randomised control study aiming to examine whether inhaled N2O/O2 during cervical preparation for second trimester dilatation and evacuation with osmotic dilators (laminaria) alleviates pain and is superior to placebo.
Children experience numerous painful experiences from nursing procedures: peripheral venous access placement is the main cause of procedural pain. As much as pharmacological and nonpharmacological tools are known, their application during venipuncture is not systematic by children's hospitals. Among pharmacological tools, the Equimolar Mixture of Nitrogen Protoxide and Oxygen (EMONO) provides adequate protection from procedural pain through inhalation of the gas mixture at least 3 minutes before the procedure. Literature reports that the combination of nonpharmacological distractive tools and pharmacological interventions increases their analgesic effect. The aim of the study is to measure children's cooperation during procedure (primary outcome), pain perception and side effects when EMONO is combined with audiovisuals compared with EMONO alone in peripheral venous access placement.
Our recent preclinical observations suggest that monitoring of slow electroencephalogram (EEG) oscillations may be used to predict the efficacy of rapid-acting antidepressants such as ketamine or nitrous oxide. In this project we will carry out critical clinical research on healthy volunteers and study the effects of nitrous oxide on EEG. Results will be used for the design of clinical trials on depressed individuals. The project will be done in collaboration between neuroscientists at the University of Helsinki and clinicians at the Tampere University Hospital.
This study compares two methods of gas delivery in a dental setting: 1) demand-driven (DD) and 2) free-flow (FF). Nitrous oxide and oxygen sedation (NOS) is a common form of minimal sedation for adult and paediatric patients undergoing dental procedures. In order for NOS devices to be utilized during dental treatment, dentists must be able to provide gas flow to the patient, and subsequently scavenge used and unused gasses. Gas delivery is via a nasal mask, since the oral cavity must be accessible to the dentist throughout treatment. Current devices for NOS in the dental setting utilize a free-flow gas method, where nitrous oxide and oxygen are released continuously from their tanks. The flow rate is set by the dentist according to the patient's minute ventilation needs, and unused and exhaled gasses are scavenged via the nasal mask. The demand-driven gas flow method, where inspiration triggers gas flow, has been used successfully in other medical settings, such as in obstetrics, medical emergencies, and for patients with chronic obstructive pulmonary disease. However, in these settings the mask used covers both the nose and mouth, and patients can trigger the demand-driven method through inspiration of the nose or mouth. The demand-driven gas flow method has a significant gas-sparing advantage over the free-flow method. With a demand-driven method, the patient dictates the flow rate and gas is only delivered when they are inspiring, compared to the free-flow method which provide gas flow throughout inspiration and expiration. However, the demand-driven method have not been studied in a dental setting where flow can only be triggered through the nose. It is therefore unknown whether it is feasible or comfortable for patients to trigger a demand-driven method nasally when their mouth is open during dental treatment. This study will aim to assess the feasibility and comfort of a nasal demand-driven gas delivery method utilizing 100% oxygen in healthy, adult participants in a simulated dental setting. If the device is feasible and comfortable with 100% oxygen in a simulated dental setting, future research can be conducted to assess its use for NOS for dental treatment.
Colon cancer is the second most common cancer in men and the third most common cancer in women worldwide. The clinical objectives of administering sedation for GI endoscopy are to relieve patient anxiety and discomfort and to improve the outcome of the examination. Use of N2O could potentially provide an alternate safe and cheap option for patients who do not prefer IV sedation for colonoscopy
Nitrous oxide gas is used in several application areas : medical as an anesthetic drug ; in food industry as a foaming and a mixing agent ; industrial to speed combustion. It is also misused for its hilarant, euphoric and hallucinogenic effect. For this purpose the gas is transfered in a balloon to be inhaled. As its effects are briefs, its consumption is often perseived as safe. However, some risks exist and are majorated by the way of use and for some groups of people. Since 2016, the French observatory of drug and substances addiction (OFDT) describes an increasing misuse of nitrous oxide amoung teenagers and young adults. In november 2019, a french press release alerts on the recent increasing of neurologic side effects related to the misuse of nitrous oxide. That's why, it seems to be interesting to improve the screening of nitrous oxide abuse, in particular amoung adolescents and young adults. In our study, the investigators would like to determine the characteristics (social, medical, any drug abuse) of teenagers and young adults who misuse nitrous oxide. Through a questionnaire, the investigators plan to select teenagers and young adults who consult in an addictology center dedicated to young drug consumers in Montpellier. This questionnaire is anonymous. The data will be collected only after obtaining the patient's agreement. The final goal is to create a tool to help general practitioners in screening young people at risk of nitrous oxyde misuse.
The study is prospective and double blind. In the clinic, patients undergoing hysterectomy that meet the criteria for inclusion into the study and agreed to participate in the study will be randomized into two groups.
Our study looks at the interaction of a common mutation in the MTHFR gene and the risk of developing higher homocysteine levels after nitrous oxide (N2O) anesthesia. Specifically, we want to test the hypothesis that healthy patients carrying the MTHFR 677C>T haplotype develop abnormal homocysteine levels after nitrous oxide anesthesia.
