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.
Intervention code [1] 257824 0
Treatment: Drugs
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.
