Filter by:The purpose of this study is to investigate the type of the cardiac disease using transthoracic echocardiography in patients whose preoperative electrocardiography shows the intraventricular conduction delay.
Coughing is a common adverse reaction of thyroid surgery,which could result in postoperative bleeding.Postoperative bleeding is a serious and potentially life-threatening complication，which could result in acute upper airway obstruction due to neck hematoma and increase the need for re-operation.The purpose of this study is to investigate whether dexmedetomidine can reduce the incidence of postoperative coughing and contribute to postoperative recovery in patients undergoing tyroid surgery with general anesthesia.
Anesthesia for emergency surgery is a situation at risk of pulmonary aspiration of gastric contents. It has been previously reported that bedside two-dimensional ultrasonography can be a useful tool for anesthesiologists to determine gastric contents and volume in adults and children. In this prospective study, preoperative qualitative ultrasound assessment of gastric contents is performed for each children admitted for emergency surgery, in order to plane in case of empty stomach an intravenous or inhalation technique induction rather than an rapid sequence induction.
The purpose of this study is to investigate whether propofol can improve quality of recovery compared to desflurane in patients undergoing robotic or laparoscopic gastrectomy.
The purpose of this study is to investigate whether the pressure controlled ventilation can reduce gastric insufflation compared to the volume controlled ventilation in patients who were mechanically ventilated with the i-gel.
Assessment of refraction measurements in children under general anesthesia, with or without cyclopelgic eye-drops
The purpose of this study is to investigate whether the pressure controlled ventilation can reduce gastric insufflation compared to the volume controlled ventilation in patients who were mechanically ventilated with the i-gel.
The purpose of this study is to find out the optimal dose for Remimazolam Tosilate as an intravenous general anaesthetic drug in operations and to determine its efficacy and safety profile comparing to propofol.
The purpose of this study is to investigate the changes of the oropharyngeal leak pressure of the air-Q self-pressurizing masked laryngeal airway in the different head and neck positions. Moreover, the adequacy of ventilation will be assessed in the different head and neck positions.
The mask ventilation is a necessary procedure to provide oxygenation before the tracheal intubation although the gastric insufflation occurs during the mask ventilation. Sugammadex, which is recently introduced, enables the use of high-dose muscle relaxant without concerning the delayed recovery of neuromuscular blockade. It seems that there is no need to perform the mask ventilation in adults with normal airway if the investigators use high-dose muscle relaxant for the anesthetic induction because adequate muscle relaxation can be achieved within 1-2 minutes. Therefore, the investigators hypothesized that routine mask ventilation is not needed in adult patients with normal airway. The investigators will compare the incidence of desaturation and gastric insufflation between the patients with mask ventilation and the patients without mask ventilation.
