To review the physiology of cardiac output regulation by the peripheral vasculature. This will enable the clinician to understand and manage the complex circulatory changes in various forms of shock, and in other common altered circulatory states encountered in anaesthetic practice. ⋯ The peripheral circulation controls cardiac output in many clinical conditions. Manipulation of the peripheral circulation is as important to the successful treatment of shock and other altered circulatory states, as is the manipulation of cardiac output.

Randomized Controlled Trial Comparative Study Clinical Trial
Vomiting after strabismus surgery in children: ondansetron vs propofol.
To compare the antiemetic efficacy and costs associated with two anaesthetic regimens in children undergoing strabismus surgery. One regimen contained halothane, nitrous oxide and ondansetron, while the other contained propofol and nitrous oxide. ⋯ The two methods of antiemetic prophylaxis were equally effective. Propofol-based anaesthesia was more expensive.

Randomized Controlled Trial Clinical Trial
Direction of injection does not affect the spread of spinal bupivacaine in parturients.
One of the factors that can affect the distribution of local anaesthetic solutions in the subarachnoid space is the direction of the spinal needle through which injections are made. This study investigated the effect of the direction of the aperture of the Whitacre needle on the spread of hyperbaric bupivacaine in parturients undergoing elective caesarean section. ⋯ The direction of the aperture of the Whitacre needle does not influence the spread of hyperbaric bupivacaine in the term parturient.

Peri-operative multimodal pain therapy for caesarean section: analgesia and fitness for discharge.
To compare, the efficacy of a multi-modal analgesic regimen and single drug therapy with iv PCA morphine alter Caesarean delivery with spinal anaesthesia. ⋯ Multi-modal pain therapy resulted in improved early post-operative analgesia during the first 24 hr after Caesarean delivery. Patients receiving iv PCA morphine followed by acetaminophen+codeine po were more likely to develop decreased bowel mobility. All patients, with one exception, achieved discharge criteria (eating solid food, absence of nausea, normal lochia, dry incision and DVAPS < 4) at 48 hr after spinal injection.

Randomized Controlled Trial Clinical Trial
Neostigmine requirements for reversal of neuromuscular blockade following an infusion of mivacurium.
To study the efficacy of neostigmine compared with placebo for the antagonism of neuromuscular blockade at the end of a mivacurium infusion, and to determine its optimal dose. ⋯ Recovery of neuromuscular blockade following a mivacurium infusion is accelerated by neostigmine. A dose of neostigmine 20 micrograms.kg-1 appears optimal with no further reduction in recovery time obtained from a larger dose.
