Abstract:
Objective? To use near-infrared spectroscopy (NIRS) to monitor the effects of peripheral artery catheterization on limb muscle oxygen saturation (SmO2) in infants and children. Methods? Totally 60 children aged under 36 months receiving selective operation in Children's Hospital, Capital Institute of Pediatrics between March and September 2017 were selected. NIRS was used to monitor and record the SmO2 of muscle of thenar or gastrocnemius muscle on the limbs of both sides before and after trachea cannula and artery cannulation under general anesthesia. The original SmO2 values of the limbs with or without cannulation were taken as controls to observe the changes of SmO2 of the limbs with cannulation after cannulation. Results? There was no statistically significant difference in original SmO2 values of the limbs with or without cannulation before cannulation (P＞0.05). The SmO2 values of the limbs with cannulation dropped after cannulation, which were lower than the values of the limbs without cannulation (P＜0.001). The decreasing range of SmO2 values of the children aged under 6 months were larger than those of the children aged between 6 and 12 months and between 12 and 36 months; and the decreasing range of SmO2 values of the children weighing under 10 kg were larger than those of the children weighing between 10 and 20 kg (P＜ 0.001). Conclusions? NIRS can accurately reflect the changes of SmO2 after artery cannulation in real time. NIRS used in monitoring helps to assess limb perfusion more precisely. Monitoring should be enhanced for limb perfusion in children aged under 6 months and weighing under 10 kg.
