Filter by:Brachial plexus block is a very reliable method of regional anesthesia for the upper limb. It achieves ideal operating conditions by producing complete muscular relaxation and stable intraoperative hemodynamics.However,Local anesthetics alone have a shorter duration of postoperative analgesia. Hence,various adjuvants have been added to local anesthetics to achieve quick, dense, and prolonged block. This study assess and compare the efficacy of dexamethasone or nalbuphine as adjuvants to local anesthetics in supraclavicular brachial plexus block for upper limb surgeries.
The stapedius reflex protects the ear from the loud noise. The measurement of the intraoperative electrically evoked stapedial reflex threshold (ESRT) during pediatric cochlear implants (CIs) is used to confirm that the implant is functioning correctly and determine the maximum comfortable level . Total intravenous anesthesia (TIVA) with propofol and remifentanil is frequently used for pediatric CIs as it does not suppress the ESRT. However, high doses of remifentanil exacerbates postoperative pain and increased opioid consumption.
Objective: Determine if, by reducing the dose of propofol and increasing the time elapsed between fentanyl and propofol administration, hemodynamic response is improved. Methods: Patients were randomized into time groups (2 and 1 minute) and each subdivided into dose groups (1, 1.5 and 2 mg kg-1) obtaining six time-dose groups. After receiving 2 μg kg-1 of fentanyl, propofol was administered after the predetermined time. Time to hypnosis (BIS<60) and hemodynamic parameters at pre-induction, pre-intubation and postintubation were registered.
The purpose of this study is to evaluate the impact of a curriculum about professionalism on stress response during a critical situation in anesthesiology residents. Residents in anesthesiology will complete a training program on professionalism during their first postgraduate year. They will go through a standardized simulated scenario where they have to manage an intra-hospital cardiorespiratory arrest and then meet the patient's family. Stress response will be assessed and compared to a control group that did not receive the training program.
Deep sedation or general anesthesia is frequently required for infant that need radiotherapy to treat malignancies. As radiation therapy usually consist of several sessions, these patients are exposure to several consecutive anesthetic exposures (e.g. for some central nervous system tumors 30 sessions of radiotherapy are required). In our center, this 30-min anesthetic exposure are with sevoflurane. Considering that repeated daily exposure to such potent drugs, as general anesthetics, may induce tolerance, it is reasonable to explore whether this phenomenon is occurring in this population. The aim of this observational study was to determine if a repeated exposure to sevoflurane is associated with the development of clinical and electroencephalographic tolerance. We will enroll 16 pediatric patients, and we will measure the time needed to appropriately place the laryngeal mask (clinical effect) and we also will compare the electroencephalographic signal under anesthesia across the different sessions (electroencephalographic effect).
The purpose of this study is to determine if a single dose of sublingual sufentanil is as or more efficacious than a single dose of IV fentanyl in a post anesthesia care setting.
It is used by music therapists to help the social, physical, emotional, psychological and psychological needs of patients. In a study, music has a positive effect on pain, anxiety, depression, shortness of breath, mood, facial expression and speech . The aim of this study was to investigate analgesia consumption during egg collection and postoperative period of music therapy and to compare and evaluate oxidative stress parameters in blood and follicle fluids.
Assessing the impact of anesthesia practice on global warming and carbon footprint becomes part of the standard of care and is growing concern within the anesthesia community. Global Warming Potential (GWP) is a measure of how much a given mass of greenhouse gas contributes to global warming over a specified time period. Inhaled anesthetics have various GWP20: 349 for sevoflurane and 3714 for desflurane. However, GWP20 and CDE20 alone are not sufficient to evaluate the environmental impact of anesthetic gases. Other parameters must be included in the analysis: fresh gas flow (FGF), carrier gas (air, O2, N2O) and potency of the anesthetic gas. Unfortunately, the majority of trials did not fully consider the FGF reduction and the fact that desflurane can be administered with new closed or very low-flow anesthesia circuits as opposed as the recommended 2L/min that must be used for sevoflurane according to its monography in Canada. Most of the calculations were made on a purely theoretical approach that could be different from actual measurements based on a strictly monitored anesthesia practice. When continuous and accurate gas monitoring and analysis is used as recommended nowadays, the use of closed or semi-closed-circuit anesthesia with very low FGF might allow for a reduction of more than 80% of the anesthetic gas administration and its consequent pollution. By properly monitoring the anesthesia depth and analgesia adequacy, the investigators can reduce the gas consumption. The proposed study will aim at determining whether with the help of high-quality monitoring (BIS and NOL) and high-end ventilators that allow minimal fresh gas flow, the use of desflurane remains more polluting than sevoflurane.
The aim of this study was to compare the risk of pulmonary aspiration assessed with gastric ultrasonography in elderly patients, undergoing elective surgery.
The purpose of this study is to evaluate the benefit of adding mental visualization to a training program in medical education. Undergraduate medical students will be randomized before participating in a training program on airway management during rapid sequence induction. In the control group, participants will receive traditional teaching including theoretical courses and procedural simulation. In the intervention group, in addition to traditional teaching, participants will be trained and encouraged to practice mental visualization. The main outcome will be clinical performance during a standardized high-fidelity simulation of rapid sequence induction assessed using a specific pre-established checklist.
