The Clinical Research Of Proseal Laryngeal Mask Airway Ofr Elderly Patients In Genearl Anesthesia

ObjectiveThrough the observation of ProSeal laryngeal mask airway and endotrachealintubation in general anesthesia for elderly patients with circulatory and respiratoryfunction, and statistical analysis, thus the ProSeal laryngeal mask airway for elderlypatients with general anesthesia of the safety and efficacy of providing basis.MethodsCollected74cases of elderly patients with general anesthesia (who and theMinistry of health regulations, China’s60years of age for the elderly) in which theLMA group (P) in36patients and intubation group (E) in38cases. Patientsburglary after routine establishment of intravenous access, monitoring and recordingbefore anesthesia, the hood (tube) after1min, the hood (tube) after3min, the hood(tube) after5min, extraction hood (pipe), remove cover (tube) after1min,extraction hood (tube) after3min, extraction hood (tube) after5min systolicpressure, diastolic pressure, heart rate, oxygen saturation, mean arterial pressure,respiratory carbon dioxide partial pressure, peak airway pressure, pull hood (tube)and postoperative adverse reaction. According to the patient’s condition: injection ofmidazolam propofol and sufentanil in0.1mg/kg,0.3-0.5ug/kg,1-2mg/kg,0.15mg/kgCIS atracurium. Induction of anesthesia. The laryngeal mask airway in patients afterimplantation of ProSeal laryngeal mask airway, tracheal intubation after induction inthe group of patients. Two groups of patients were receiving anesthesia machine formechanical ventilation, tidal volume of8ml/kg, frequency of12times/min.Anesthesia was maintained by propofol remifentanil and atracurium, intravenousinfusion. After the end of operation for spontaneous breathing recovery, calls can be,pull out the laryngeal mask or catheter, blood saturation>95%, send back ward. esults1. To compare all indexs of P group and E group at different time points, theconclusion is as follows: systolic blood pressure (F=0.036, P=0.850), diastolicpressure (F=2.566, P=s0.118), the blood oxygen (F=0.013, P=0.909), heart rate(F=0.363, P=0.55)，mean arterial pressure (F=0.497, P=0.486) and respiratorycarbon dioxide partial pressure (F=0.271，P=0.605) of the mean of populationbetween the two groups were no statistically significant differences (P>0.05), Butpeak airway pressure (F=103.535，P<0.001), of the mean of population between thetwo groups were statistically significant differences (P <0.05);2. To compare the index between the two group at each time, P group insheathing (tube)1minute systolic blood pressure is obviously higher than that of Egroup significant difference (t=-2.319，P=0.023),E group in sheathing (tube)1minute,sheathing (tube)3minutes and pull cover (tube)5minute diastolic pressure isobviously higher than that of P group, significant difference (t=2.786, P=0.008; t=2.161, P=0.036; t=2.248，P=0.028); In group E pull cover (tube)1minute after heartrate is obviously higher than that of P group, significant difference(t=2.315，P=0.023);In group P sheathing (tube)1minute mean arterial pressure is obviously higher thanthat of E group, significant difference (t=-2.997，P=0.004); The rest of the index ineach time all is showed significant difference (P>0.05); In the P group deactivatedwhen breathing carbon dioxide partial pressure was significantly higher in E group,the difference was statistically significant (t=-3.128, P=0.003) the remaining time arenot statistically significant. In group P after1minutes (t=19.679, P<0.001), after3minutes (t=17.346, P<0.001), after5minutes (t=14.824, P<0.001) were statisticallysignificant, and deactivated when the peak airway pressure without statisticalsignificance.3. A total of2patients appear in nausea phenomenon in the group E, P groupappear10cases, existing significant differences between the two groups (2=5.864, P=0.015); E group5patients appear in choke cough phenomenon in the group E, P group appear in15cases, statistical significance was found between two group (2=6.136, P=0.013).Conclusion1. ProSeal laryngeal mask airway and endotracheal intubation in the elderlypatients with general anesthesia, blood pressure, heart rate, bloodoxygenation and mean arterial blood pressure and respiratory carbon dioxidepartial pressure groups with no significant difference between the2. The ProSeal laryngeal mask airway and endotracheal intubation in theelderly patients with general anesthesia, mean arterial pressure and bloodpressure in use after1minutes when there are differences in heart rate; in1minutes after1minutes and deactivated when there was a discrepancy;respiratory carbon dioxide partial pressure difference in time.3.The ProSeal laryngeal mask airway for elderly patients with generalanesthesia, postoperative sore throat, hoarseness, cough and lower than the incidenceof tracheal intubation, safe and effective.
