Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
maintenance of low flow Anestheia with volume controlled ventilation through Laryngeal Mask Airway(LMA)with sevoflurane(Inhaled anesthetic) with 2-2.5% in initial phase(10 minutes) and after that maintained on 3-3.5% till we reach near the time of ending operation., at first we set fresh gas flow at 6 lit/min and after that the fresh gas flow decreases to 1lit/min during 10-15 minutes. hemodynamic parameters will be monitored.

Comparator / control treatment
maintenance of low flow Anestheia with volume controlled ventilation through Laryngeal Mask Airway(LMA)with isoflurane(inhaled anesthesia) with 1.5-2% isoflurane for 10 minutes and after that 1-1.5% till we reach near the time of ending operation.at first we set fresh gas flow at 6 lit/min and after that the fresh gas flow decreases to 1lit/min during 10-15 minutes.hemodynamic parameters will be monitored.

Summary
Brief summary
Laryngeal Mask Airway(LMA) is a good device for airway management which is used routinly in operating room nowadays.Low flow anesthesia is almost a new concept in maintenance of anesthesia which leads to better control of airway temperature and humidity with stable hemodynamic.
Previous studies showed that we can use isoflurane with controlled low flow anesthesia during operation. Sevoflurane is a new anesthetic which has some priorities to other anesthetics. But there are some concerns about its use during contooled low flow anesthesia with LMA. 80 patients will be enrolled in this study. Patients will be randomized to two 40 patient groups. In one group anesthesia will be maintained with isoflurane and in the other group will be maintained by sevoflurane. All patients will be ventilated through LMA with low flow anesthesia. Hemodynamic Parameters will be noted during anestheia for each person.
