Central venous blood oxygen saturation (ScvO2) is an important monitoring index of fluid resuscitation. However, monitoring of ScvO2 is not continuous and invasive. Near infrared spectroscopy (NIRS) is an optical technology for the noninvasive detection of hemodynamic changes, with advantages of being real-time, continuous, low-cost, and portable. ⋯ Results were as follows: 100% of monitored points fell within the range of the mean ± 1.96 SD of the difference between the StO2 and ScvO2; range of the mean ± 1.96 SD of the difference between the StO2 and ScvO2 was 3 ± 10.2; confidence interval of the difference between the StO2 and ScvO2 was -7.2 to 13.2%. The StO2 monitored with NIRS correlated highly with the ScvO2 measured in the internal jugular vein. Therefore, the StO2 can be used for directing clinical treatment with further research.

Randomized Controlled Trial
Safety of recombinant human granulocyte-macrophage colony-stimulating factor in healing pediatric severe burns.
We explored the safety of recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) for healing burns in children. Subjects were randomly assigned to two groups: the experimental group received external rhGM-CSF gel, and the control group received rhGM-CSF gel matrix components, applied to the burn surface. Neither group was given any other drugs that promote wound healing. ⋯ There were no obvious adverse reactions. There was no significant difference between the blood routine, urine routine, and liver and kidney function in the two groups before the treatment and after 3 days (P > 0.05). Compared with saline treatment of severe burns, rhGM-CSF can effectively shorten the healing time without significant adverse reactions, and is an effective and safe treatment for burns in children.
