NCT04507295

Brief Summary

the aim of this study is to compare the effect of different modes of mechanical ventilation by using volume-controlled ventilation and pressure-controlled ventilation on cerebral blood flow monitored by cerebral oximetry during thoracoscopic surgeries in neonates.

Outcome Measures

Primary Outcomes (1)

  • cerebral saturation

    the cerebral oxygen saturation ( % ) will be measured using the cerebral oximetry(INVOS 5100) and will be recorded before induction of anesthesia then every 15 minutes after induction of anesthesia and any attack of cerebral desaturation is recorded

    during the whole duration of surgery

Secondary Outcomes (5)

  • oxygen saturation ( SPO2 )

    during the whole duration of surgery

  • arterial partial pressure of carbon dioxide ( PaCO2 )

    during the whole duration of surgery

  • End Tidal CO2 ( ETCO2 )

    during the whole duration of surgery

  • Positive End Expiratory Pressure ( PEEP )

    during the whole duration of surgery

  • Fraction of inspired oxygen

    during the whole duration of surgery

Study Arms (2)

volume controlled group

ACTIVE COMPARATOR

15 patients in is this group will be ventilated during capnothorax using volume controlled ventilation with the following parameters: * FIO2 of 60 %. * Tidal Volume (TV) of 6-8 ml/kg. * Respiratory rate of 30 breathes/min then the respiratory rate will be modified to maintain the ETCO2 between 30-35 mm Hg. * inspiratory to expiratory ratio (I: E) 1:2. * using a minimal Positive End Expiratory Pressure (PEEP) of 2 cm H2O.

Device: cerebral oximetry ( INVOS 5100 )

pressure controlled group

ACTIVE COMPARATOR

15 patients in is this group will be ventilated during capnothorax using pressure controlled ventilation with the following parameters: * FIO2 60 %. * inspiratory pressure adjusted to fulfil the required TV according to the weight of the patient (6-8 ml /kg) then the insufflation pressure will be added to the driving pressure. * respiratory rate of 30 breathes/min then the respiratory rate will be modified to maintain the ETCO2 between 30-35 mm Hg. * I:E ratio of 1:1.5 . * Using a minimal PEEP of 2 cm H2O.

Device: cerebral oximetry ( INVOS 5100 )

Interventions

in case of critical cerebra desaturation occurred which is defined as decrease in cerebral saturation by 20% from the base line the following will be done 1. Increase FIO2 up to 100% 2. Increase PEEP up to 5 cmH2O 3. Decrease insufflation pressure
