Indications for Drugs ::
Postpartum haemorrhage, Labour induction, Abortion, Facilitate lactation
Drug Dose ::
Intravenous Adjunct in abortion Adult: 10-20 milliunits/minute. Max total dose: 30 units in a 12-hr period. Postpartum haemorrhage Adult: 10-40 units by infusion in 1000 mL of IV fluid at a rate sufficient to control uterine atony. Labour induction Adult: 1-2 milliunits/minute, may increase at intervals of at least 30 minutes until a max of 3-4 contractions occur every 10 minutes. Not to exceed 32 milliunits/minute and no more than a total of 5 units should be given in 1 day. Not to be given within 6 hr after admin of vaginal prostaglandins. Monitor uterine contractions and foetal heart rate continuously. Withdraw gradually once labour is progressing. Oxytocin challenge test for evaluating of foetal distress Adult: Dilute 5-10 units in 1 L of 5% dextrose inj. Initially, administer the drug in the mother via IV infusion at a rate of 0.5 milliunits/minute. May gradually increase infusion rate at intervals of 15-30 minutes. Max: 20 milliunits/minute. Monitor foetal heart rate and uterine contractions immediately before and during infusion. Discontinue infusion when 3 moderate uterine contractions occur within one 10-minute interval. Compare baseline and oxytocin-induced foetal heart rates. If no change occurs, repeat the test in 1 wk. Termination of pregnancy may be required if a late deceleration in foetal heart rate occurs.
Cephalopelvic disproportion; abnormal presentation of the foetus; hydraminios; multiparae; previous caesarian section or other uterine surgery; hyperactive or hypertonic uterus, uterine rupture; contraindicated vaginal delivery (invasive cervical cancer, active genital herpes, prolapse of the cord, cord presentation, total placenta previa or vasa previa); foetal distress where delivery is not imminent; severe pre-eclamptic toxaemia.
Drug Precautions ::
CV disorders; >35 yr; lactation. Monitor foetal and maternal heart rate, maternal BP and uterine motility. Monitor fluid intake and output during treatment. Discontinute immediately if the uterus is hypertonic or hyperactive or if there is foetal distress. Use of nasal spray may produce maternal dependence on its effects. IM admin not regularly used due to unpredictable effects of oxytocin. Not to be used for prolonged periods in resistant uterine inertia, severe pre-eclampsia, or severe CV disorders. Risk of water intoxication when used at high doses for prolonged periods.
Drug Side Effects ::
Foetus or neonate: Jaundice; arrhythmias, bradycardia; brain, CNS damage; seizure; retinal haemorrhage; low Apgar score. Mother: transient hypotension, reflex tachycardia; nasal irritation, rhinorrhoea, lachrymation (following nasal admin); uterine bleeding, violent contractions, hypertonicity; spasm; nausea, vomiting. Potentially Fatal: Maternal water intoxication (especially with slow infusion over 24 hr); prolonged uterine contractions causing foetal hypoxia and death; rupture of gravid uterus; afibrinogenaemia; subarachnoid haemorrhage
Pregnancy category ::
Drug Mode of Action ::
Uterine stimulant, vasopressive, & antidiuretic effects; activates G-protein-coupled receptors that trigger increases in intracellular calcium levels in uterine myofibrils, which results in uterine contractions; increases local prostaglandin production, which further stimulates uterine contraction.
Drug Interactions ::
Possible severe hypertension if given within 3-4 hr of vasoconstrictor in association with a caudal block anaesthesia. Cyclopropane anaesthesia may increase risk of hypotension and maternal sinus bradycardia with abnormal AV rhythms. Dinoprostone and misoprostol may increase uterotonic effect of oxytocin, thus oxytocin should not be used within 6 hr after admin of vaginal prostaglandins. Concurrent use may increase the vasopressor effect of sympathomimetics. Potentially Fatal: Concomitant use with prostaglandins increases risk of uterine rupture and cervical lacerations.
