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.

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
Low incidence of the oculocardiac reflex and postoperative nausea and vomiting in adults undergoing strabismus surgery.
To investigate the incidence of the oculocardiac reflex (OCR), and of postoperative nausea and vomiting (PONV) in adults undergoing strabismus surgery. ⋯ Adults undergoing strabismus surgery with prophylactic atropine had a low risk of OCR and PONV, independent of the anaesthetic technique used.

Light-guided retrograde intubation.
Transillumination of the soft tissues using a lightwand (Trachlight) can guide the endotracheal tube (ETT) into the glottis to facilitate the retrograde intubation. This study evaluated the effectiveness and safety of this intubating technique for patients with cervical spine instability. ⋯ In a small number of patients, we have shown that light-guided retrograde intubation is effective and sale for patients with cervical spine instability. This simple and inexpensive technique may prove to be a valuable adjunct in the management of difficult airways.
