the purpose is a one-off double tube laryngeal mask ( LMA Supreme) With the traditional double tube laryngeal mask ( LMA Proseal) When used in patients with general anesthesia, the placement time, success rate, oropharynx, sealing, counterpoint, stomach tube, pharyngeal injury and blood flow dynamics and other differences. Methods select 60 ASA Ⅰ ~ Ⅱ level, ages 18 to 75 years old patients, randomly divided into P ( LMA Proseal) And S ( LMA Supreme) The two groups. The patient supine position. Induced by Rayleigh fentanyl and propofol target control input, the target concentration were 3 ng/ml and 4 ng/ml, the interaction between rocuronium 0. 6 mg/kg of single intravenous injection. Observe and record of two kinds of laryngeal mask to establish effective ventilation time, success rate of placement, oropharynx, sealing pressure, registration ( Bronchoscopy observe the glottis exposure in the mirror, divided into 1, 2, 3, 4) Pharyngeal damage, stomach tube placement and patient, and blood pressure, heart rate changes. Surgery patients pharyngeal pain after 24 hours. Results P group set up effective ventilation time significantly longer than S group. In the success rate for the first time to S group was obviously higher than that of P group. No statistical difference was found between two groups of oropharyngeal sealing. No statistical difference was found between two groups of ventilation pressure. Fiberoptic bronchoscopy vision ratings of S group was obviously better than that of P group ( P0。 05) 。 After the surgery, two groups of laryngeal mask has not been found visible blood on his body, two groups of patients after 24 hours of sore throat rate has no obvious difference. Two groups of patients with systolic pressure, diastolic blood pressure, heart rate in all selected point in time no statistical difference. Conclusion compared with the traditional double tube laryngeal mask, one-time double tube laryngeal mask into a high success rate, counterpoint is more ideal, in the short time, high success rate of gastric tube is placed. Two kinds of hemodynamic changes before and after laryngeal mask placement has no obvious difference.
