Perioperative considerations in the management of the patient taking herbal medicines.
The use of herbal products has recently increased dramatically in the United States. Patients are flocking to use these and many other complementary or alternative therapies. ⋯ The following review will discuss the limitations of Food and Drug Administration protection, and will review as well as provide an outline of the potential adverse reactions and side-effects that might affect anesthesia administration. To date, no double-blind, placebo-controlled studies have been carried out that specifically address herbal-anesthetic interactions or outcomes.

Patient-controlled epidural analgesia or continuous infusion: advantages and disadvantages of different modes of delivering epidural analgesia for labour.
Patient-controlled epidural analgesia, intermittent top-up and continuous infusion are equally effective in providing epidural pain relief during labour. Patient-controlled epidural analgesia is associated with a significant reduction in hourly dose requirements when compared with continuous infusion, and by transferring the responsibility for epidural top-up, it offers the parturient the psychological benefit of being in control. ⋯ However, the safety of the method needs to be documented more extensively, and the advantage of a reduction in hourly dose requirements needs to be visualized in terms of an improvement in labour or neonatal outcome. Moreover, the optimal dose, drug combination and settings still remain to be determined.

Over the years, ketamine has found many applications in paediatric anaesthesiology. Recent insights into the mechanism of its central action, and the pharmacology of its isomers have led to a re-evaluation of this drug, expanding the range of indications in adults. The best examples of the uses of ketamine as an analgesic are: in brief diagnostic or therapeutic procedures, during the post-operative period in neonates and infants as well as in paediatric anaesthesia and intensive care.
