Subjects in the 150 IU group received a subcutaneous infusion of 500 mL Ringer's lactated sodium into the lateral thighs bilaterally on D1, 250 mL Ringer's lactated sodium into the upper arms bilaterally on D2, 500 mL sodium chloride injection into the lateral thighs bilaterally on D3, and 1,000 mL Ringer's lactated sodium into the back on D4, as scheduled.
Subjects in the 385 IU group received a 250 mL subcutaneous infusion of Ringer's lactated sodium into the bilateral upper arms on D1 as scheduled.
