Randomized Controlled Trial Comparative Study
CobraPLUS and Cookgas air-Q versus Fastrach for blind endotracheal intubation: a randomised controlled trial.
CobraPLUS and Cookgas air-Q are supraglottic airways expected to allow safe ventilation as well as reliable blind intubation. In a prospective, controlled trial, we hypothesised that quality of ventilation and success rate of blind endotracheal intubation of these new devices would be superior to the Fastrach intubating laryngeal mask airway (ILMA). When blind intubation failed the quality of fibrescope-guided intubation was investigated. To allow identification of those patients in whom blind intubation would be difficult, we investigated the predictive value of currently used predictors for ease of endotracheal intubation. ⋯ All devices appeared to be safe airways. The Fastrach ILMA proved to be a reliable facilitator for blind intubation. CobraPLUS and Cookgas air-Q allowed an easy fibrescopic intubation. Failed blind intubations could not be predicted by the used parameters.

Randomized Controlled Trial Comparative Study
Antishivering effects of two different doses of intrathecal meperidine in caesarean section: a prospective randomised blinded study.
Shivering causes various adverse disturbances and interferes with monitoring. The optimal dose of intrathecal meperidine to prevent shivering without producing other side-effects remains unknown. This prospective randomised double-blinded study was conducted to compare the antishivering effects of two different doses of intrathecal meperidine. ⋯ The use of intrathecal meperidine for caesarean section during spinal anaesthesia for the prevention of shivering cannot be recommended as its use is associated with increased incidence of nausea and vomiting.

Randomized Controlled Trial
Randomised controlled trial of the effect of oral premedication with dexamethasone on hyperglycaemic response to abdominal hysterectomy.
This study was performed to evaluate the metabolic effects of a single oral dose of 8 mg dexamethasone in women undergoing hysterectomy. ⋯ Amounts of dexamethasone frequently used for prophylaxis of post-operative nausea and vomiting can cause short-lasting hyperglycaemia in the post-operative period, but no relevant alterations in fat metabolism. Thus, the benefits of administering corticosteroids should be weighed against the potential side-effects of short-lasting hyperglycaemia.
