Anesthetics and Cerebral Oxygenation in LSG

Oxygen/air (fraction of inspired oxygen (FiO2) of 0.40), inspiratory fresh gas flow of 2 L/min), sevoflurane (1 minimum alveolar concentration \[MAC\]) and remifentanil IV infusion (0.1-0.25 mcg/kg of LBW/min) were used.Neuromuscular blockade was performed during the operation by rocuronium infusion (0.3-0.7 mg/kg of LBW/h), ensuring that PTC was zero.

Propofol infusion (4-8 mg/kg of total body weight/h), oxygen/air (FiO2 of 0.40; inspiratory fresh gas flow of 2 L/min) and remifentanil IV infusion (0.1-0.25 μg/kg of LBW/min) were used.Neuromuscular blockade was performed during the operation by rocuronium infusion (0.3-0.7 mg/kg of LBW/h), ensuring that PTC was zero.
