- 1.As the author stated the study was conducted at an academic hospital located in a city with a population of 1,000,000 with >24,000 visits to the PED each year, however, only 34 children were enrolled in this study over 10 months and the recruitment rate is too low. Can authors provide the number of children who were excluded from enrollment?
- 2.The study included children with vomiting or diarrhea who requiring fluid resuscitation and excluded patients with life-threatening shock. Of the enrolled patients, are there any patients with hypovolemic shock for vomiting or diarrhea, or septic shock for infectious diarrhea? If so, are they excluded or not?
- 3.As the ultrasound measurement conducted by an experienced physician, many patient-related factors such as obesity, lung hyperinflation, pneumothorax, and abdominal gaseous distention may still lead to measurement failed [
- 4.Ao/IVCA used to determine the effects of fluid administration was evaluated under the assumption that the preload was increased by the fluid administration. Studies have shown that only 25% of the crystalloid infusion which was infused for 30 min prior to cesarean delivery remained in the blood [] and only 5% or less remained in the blood after 1 h in septic patients [,
- 5.In addition, we fund there were some mistakes in this paper, for example, 1) the data of the age in Table 1 was missing; 2) the last sentence of abstract, “Ao/IVCA showed better correlations with the volume of fluid administered than IVCI and Ao/IVCA” should be corrected to “Ao/IVCA showed better correlations with the volume of fluid administered than IVCI and Ao/IVCD”.
