Oxygen saturation

Sevoflurane is considered to be a safe volatile anesthetic that, in usual concentrations, does not cause any severe side effects on respiration. Uptake of sevoflurane from the lung and recovery from general anesthesia are both rapid and smooth. However, we have sometimes observed slightly lower pulse oximetry (Spo2) values than expected when infants under 3 years of age were ventilated with sevoflurane and nitrous oxide/oxygen. A similar phenomenon has not been observed during general anesthesia in older children or adults. The aim of this study was to determine if the decrease in SpOz during general anesthesia with sevoflurane is anesthetic specific or shared by other agents, such as enflurane or isoflurane, in combination with different concentrations of nitrous oxide. canadian pharmacy viagra
