Oxytocin may be used to induce or hasten labor, control postpartum hemorrhage, etc. It is given in doses appropriate to the therapeutic purpose and is administered either intravenously or intramuscularly. For inducing or hastening labor, 2.5-5 units per dose is usually administered intravenously using sodium chloride injection diluted to 0.01 unit per 1 mL. During the first 15 minutes of intravenous infusion, the dose should not exceed 0.001-0.002 units per minute. 15-30 minutes, the dose can be increased by 0.001-0.002 units, and the fastest dose should not exceed 0.02 units per minute. Hysterectomy is used to control postpartum hemorrhage, 0.02-0.04 units per minute intravenously, and 5-10 units intramuscularly after delivery of the placenta. In patients with cardiovascular disease, the amount of intravenous fluid should be appropriately reduced and the drip rate must be slowed down. The fluid volume should also be smaller when larger doses are applied for prolonged periods of time, and the IV fluid must contain electrolytes to avoid water intoxication. Pregnant women should be carefully monitored for fetal heart rate and contractions, and the dose should be adjusted according to individual response. This product should only be administered in a hospital under medical supervision. Rapid intravenous and intramuscular administration is prohibited for prenatal use. It is recommended that the use of oxytocin be under the supervision of a doctor and not be used blindly.
