Filter by:Emergence agitation (EA), a phenomenon observed at the time of recovery from general anesthesia (GA).The cause of ED appears to be multifactorial in origin. Use of volatile anesthetics, prolonged duration and type of surgery, pain, and rapid emergence are some factors known to increase its incidence
Peri-operative opioid administration has long been one of the three pillars of 'balanced anaesthesia',over the span of just a few years,opioids were widely used in perioperative analgesia because of pain as the fifth vital sign.However, opioid administration is not without concern and is associated with many side-effects such as constipation, urinary retention, respiratory depression and postoperative nausea and vomiting .Cleft lip,palate,alveolus are common craniofacial abnormalities and usually require surgical repair.These patients have risks for various perioperative complications due to their young age and craniofacial abnormalities. This study was designed to compare the effects of opioid based anesthesia（OBA） and opioid free anesthesia(OFA )on perioperative complications in patients with in cleft lip,palate,alveolus surgery, including respiratory depression, postoperative nausea and vomiting, hemodynamic effects, etc.
Preoperative anxiety is often described as an uncomfortable, tense unpleasant mood before surgery, an emotional response to a potential challenge or threat to reality. Data show that adult patients with preoperative anxiety rate of 30-40%. The main reason for the occurrence of patients for surgery, anesthesia and other factors of fear. Preoperative anxiety itself is not a mental illness, but studies have confirmed that the occurrence of preoperative anxiety and postoperative complications were positively correlated, and the existence of preoperative anxiety in patients with conventional postoperative analgesic effect is poor. At present, there are still few studies on the relationship between preoperative anxiety and postoperative complications and analgesia. At the same time, there is a lack of large sample size to study the incidence of preoperative anxiety and its related predictors.
Since the introduction of propofol into routine anesthesia practice, the phenomena of pain on injection has plagued anesthesia providers. Propofol, an unstable phenol, triggers the release of bradykinin on injection. This release causes a painful burning sensation in the patient at the site of injection. Anesthesia providers have attempted a large number of remedies to prevent this pain on injection. Previously explored ideas include injecting propofol into larger veins, warming of the hand with hot packs, and intravenous pretreatment with numerous other medications. Currently, pretreatment with lidocaine is commonly administered to prevent propofol injection pain. No studies to date have looked at the combination of lidocaine and magnesium in a single syringe for the pretreatment of pain on injection caused by propofol. In addition, the administration protocols that have been studied thus far do not mirror clinical practice at the University of Wisconsin. The investigators propose studying the use of magnesium and lidocaine in a single syringe for pretreatment of propofol related pain on injection.
