Filter by:Patients undergoing anesthesia for non-cardiac surgery will be randomized to either having their anesthesia team alerted or kept blinded to extended periods of less than normal blood pressure with the goal of studying if providing these alerts leads to improved outcome after surgery (lower risk of death or complication in the days and weeks following surgery).
COPD (Chronic obstructive disease ) is a condition of respiratory system failure seen occasionally in elderly patients of society. Sevofluorane is a safe, volatile anesthetic used considerably widely all over the world. Because respiratory functions and gas exchange became impaired in COPD patients, the respiratory system excretion/washout of inhalational anesthetic agents can be affected. In our study we aimed to investigate if there is a relation between sevofluorane's washout time and the degree of COPD.
To explore the feasibility of different doses of etomidate admixed with propofol in induced abortion: a randomized, double blind controlled trial.
This a study to retrospectively review our experience with the use of chloroprocaine for postoperative epidural infusions in neonates and infants. Pain scores and the need for intravenous analgesic agents will be recorded from the records to demonstrate the efficacy of the technique.
One of the most common side effects of a surgical procedure is infection. In order to lower the number of infections that occur after surgery, it is important for physicians to know how medications used during surgery affect the way the body fights infection. Often, when anesthesiologists are helping people go to sleep before surgery they give people medications known as "volatile anesthetics". Volatile anesthetics are medications that can change from a liquid or solid to a gas very easily. Some studies suggest that these types of medications may change the way white blood cells work in the body. Changing the way white blood cells work could possibly increase the person's risk of infection after their surgery or weaken their body's ability to fight infections. The goal of this research study is to learn about how volatile anesthesia medications change the way white blood cells work in people having anesthesia for cardiac procedures. To do this, investigators will examine the function of while blood cells in the laboratory based setting.
Ketamine seems an obvious choice in the setting of an emergency department in laceration repair. Lidocaine is the local anesthetics widespread used. Ketamine leads to dissociative amnesia. Theoretically , lidocaine is not useful in laceration repair using ketamine. However, lidocaine is used with ketamine in many emergency department. The investigators compare lidocaine with placebo as an adjunct to ketamine sedation in children undergoing primary closure
To explore the effect of induction and maintenance of anesthesia with etomidate on hemodynamics and oxidative stress in diabetic patients.
Based on China's guangxi guilin for a hernia operation in 1 to 3 years old preschool children propofol and etomidate on behavioral and cognitive function after intravenous anesthesia in according to beta protein in serum and plasma glutamate (Glutamic acid, Glu) and gamma-aminobutyric acid (Gamma aminobutyric acid, GABA) level of observation, the rapid development period children's cognitive function after anesthesia short-term and long-term change process and its possible mechanism is studied, for the current international debate on "anesthetics effects on developing kids brain nerve" research hot spot in the city of clinical basis and research argument, for pediatric anesthesia clinical safety, provide theoretical basis for the rational use of drugs.
During general anesthesia the basic non-invasive monitoring of hemodynamic parameters (blood pressure, O2-saturation, cardiogram) is crucial. It can be enhanced to so called "extended hemodynamic monitoring" depending on the operation and patient. Frequently an invasive arterial cannula is used to provide continuous information on the blood pressure. This invasive method is very accurate and clinically established, but can be linked to adverse effects e.g. reduction of the circulation flow distal of the canulla, haematoma, infection etc. ccNexfin (Edwards Lifescience) is a finger cuff measuring the blood pressure in a non-invasive manner. It thus offers beat-to-beat information even about the extended hemodynamic parameters as cardiac output (CO), cardiac index (CI), stroke volume (SV), stroke volume index (SVI) and stroke volume variation (SSV), if connected to the clinical platform EV1000 (Edwards Lifescience). Assuming that the two methods are equal we plan to measure extended hemodynamic parameters before, during induction and during ongoing anesthesia both invasive and non-invasive. Data will be recorded every 30sec. Clinical evaluation of the ccNexfin technology in respect to extended hemodynamic parameters is to our knowledge rare and further assessment in this field is needed to offer patients a potentially equally reliable but less invasive monitoring. Furthermore the study should model the effect of remifentanil, propofol or its combination on haemodynamics .
Forefoot surgeries involve a relatively short operation usually completed in 1 - 1½ hours, with patients generally being allowed to go home on the same day. Despite this, post-surgery pain is often severe and a delay in the discharge of patients due to difficulty with pain control after the surgery is common. Performing nerve blocks in association with sedation is the preferred way to provide pain relief and offers important benefits for foot surgeries. With nerve blocks, the requirement for oral painkillers and their associated side effects is reduced. Increasing the duration of local anesthetic action is helpful as it increases the time of pain relief, allowing for a smoother transition to oral pain medications, earlier discharge, and faster recovery. Recently, Precedex has been considered for its usefulness in prolonging the pain relief produced by nerve blocks. The identified benefits of this particular use include reducing post-surgical pain medications requirements, reducing the incidence of nausea and vomiting, reducing the incidence of sedation from such medication, and diminishing the incidence of respiratory depression (inadequate breathing). Two small studies have also shown that adding dexmedetomidine to nerve block solution results in prolonging pain relief. The purpose of the study is to examine several doses of dexmedetomidine combined with local anesthetic drugs and determine the best combination for prolonging pain relief, while minimizing potential side effects.
