Pressure Support Ventilation
Ventilator will be adjusted to administer pressure at 10 cmH2O.
Unparalyzed Pressure Control Ventilation
Pressure controlled ventilation mode will be applied to obtain a volume of 8 ml/kg up to 20 cmH2O. The set respiratory rate will be 15 breaths/min then it is adjusted to achieve the end tidal CO2 levels between 35 and 40 mmHg as measured by capnography.
Paralyzed Pressure Control Ventilation
Pressure controlled ventilation mode will be applied to obtain a volume of 8 ml/kg up to 20 cmH2O. The set respiratory rate will be 15 breaths/min then it is adjusted to achieve the end tidal CO2 levels between 35 and 40 mmHg as measured by capnography. Also, neuromuscular blockade will be achieved.
Laryngeal Mask Airway
Capnography connected to laryngeal mask airway is introduced after adequate jaw relaxation; its size is chosen according to the body weight of the child.
Sevoflurane
Sevoflurane in air/oxygen mixture of 40% will be titrated to achieve adequate depth of anesthesia to maintain immobilization of the eye.
