Filter by:To determine the median effective concentration of ropivacaine hydrochloride for ultrasound-guided supraclavicular brachial plexus block. The result can provide reference for choosing appropriate drug concentration in clinical anesthesia.
We want to evaluate the efficacy of the glycopyrrolate and atropine for the prevention of catheter-related bladder discomfort.
- The perioperative period can be a significant source of psychological burden, anxiety and fear for patients - Both pharmacological and non-pharmacological methods have been proposed in order to alleviate perioperative stress - Music is one of the non-pharmacological methods which have been used in this context, with favorable effects both preoperatively and postoperatively - The attenuation of perioperative stress through music listening is probably due to the activation of emotional and cognitive processes that evoke feeling of pleasure and can distract patients' attention from fear and unpleasant thoughts related to the surgical procedure - Little information is available regarding the effect of intraoperative music listening on anesthetized, unconscious patients - There is a notion that general anesthesia does not completely abolish auditory perception and that some processing of intraoperative events can occur in unconscious patients, even in the absence of postoperative recall - The investigators hypothesis is that intraoperative music listening can decrease anesthetic requirements and reduce sevoflurane consumption in female patients subjected to abdominal hysterectomy for benign disease.
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
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.
Prospective association study to analyse perioperative patients' outcome. Outcome comprises intraoperative and postoperative complications e.g. cardio-vascular events, allergic reactions, Possible variables which might have on influence: patient- and surgery-related data, patients' genetic background etc.
To study the safety and efficacy of Hand Held Nitrous. A device that delivers 120 seconds of up to 72% nitrous oxide and ambient air.
- Major surgery can lead to postoperative disturbances in sleep patterns with subjective deterioration of sleep quality according to patients' reports as well as objective alterations of sleep architecture, as recorded by polysomnography - Factors implicated in postoperative sleep disturbances include but are not limited to the severity of the surgical procedure, the neuroendocrine response to surgery, inadequate treatment of postoperative pain and external factors interfering with sleep, such as light, noise and therapeutic procedures - There are differences in the molecular mechanisms inhalational anesthetics and intravenous agents affect different brain regions to induce anesthesia. Our hypothesis is that these differences may also be evident during the postoperative period, affecting brain functions which are involved in postoperative sleep architecture. So, the aim of this study will be to assess the effect of two different anesthetic techniques (propofol versus desflurane) of maintaining general anesthesia in patients subjected to similar major operations - Patients will be assessed with the Pittsburgh Sleep Quality Questionnaire (PSQI), regarding preoperative and long term postoperative sleep quality, sleep diaries regarding early postoperative sleep quality and biochemical markers (cortisol, prolactin and melatonin) regarding neuroendocrine response to surgery and disturbances in endogenous circadian secretion associated with sleep
General anesthesia can be considered as a combination of hypnosis, antinociception and immobility. Explore the effect of three kinds of anesthesia,that is the total intravenous anesthesia, inhalation anesthesia and inhalation and intravenous anesthesia on stress reactions generated by patients with diabetes conducted gastric - bypass surgery , and choose a best way from three kinds of anesthesia to control stress reaction of diabetics. After selecting the appropriate anesthesia method, assess the effect of dexmedetomidine on controlling stress response from diabetics undergoing laparoscopic gastric-bypass surgical.
Unsedated ultrathin transnasal esophago-gastro-duodenoscopy (UT-EGD), in comparison with conventional peroral EGD (P-EGD) has been shown to be more tolerable, safer, cost-effective and time-efficient. The investigators and in other studies have showed that nasal pledgetting (or commonly termed nasal packing) is better than nasal spray in terms of patient tolerance and visual capacity. Although pledgetting method to a selected meatus can achieve better decongestion effect, epistaxis and nasal pain in some patients are still frustrating to endoscopists. The investigator has proposed a novel meatus scoring scale to evaluate nasal insertability by anterior rhinoscopy using a transnasal endoscope. The investigator also suggest endoscopic-guided gauze pledgetting can provide precise nasal anesthesia, thereby reducing trauma/bleeding in the nasal cavity and increasing patient tolerance during transnasal endoscopy. Endoscopic guidance to deliver a gauze strip can confirm delivering it to at least the posterior end of a turbinate. We hypothesize that by using endoscopic-guided method, gauze pledgetting to both the inferior nasal meatus (INM) and middle nasal meatus (MNM) simultaneously is more tolerable than only gauze pledgetting to a single meatus.
