The administration of oxytocic drugs during caesarean section is an important intervention to prevent uterine atony or treat established postpartum haemorrhage. Considerable past and current research has shown that these agents have a narrow therapeutic range. A detailed knowledge by anaesthetists of optimal doses and side effects is therefore required. Oxytocin remains the first line agent. In view of receptor desensitisation, second line agents may be required, namely ergot alkaloids and prostaglandins. This review examines the adverse haemodynamic and side effects, and methods for their limitation. An approach to dosing and choices of agent for the limitation of postpartum haemorrhage is suggested.

Local Anesthetics: Clinical Application as Epidural Anesthesia
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by anesthetizing...
