Randomized Controlled Trial Comparative StudyParasacral sciatic nerve block: does the elicited motor response predict the success rate?
In this prospective, randomized, double-blind study, we compared the tibial and the peroneal evoked motor response with regard to efficacy of sciatic nerve block using the parasacral approach. ⋯ Eliciting a tibial motor response predicts a higher success rate than eliciting a peroneal motor response with parasacral sciatic nerve block.

Randomized Controlled Trial Comparative StudyThe antipruritic and antiemetic effects of epidural droperidol: a study of three methods of administration.
In this study, we compared rates of postoperative nausea and vomiting (PONV) and pruritus after using different protocols for administering epidural droperidol. ⋯ Epidural droperidol is effective for reducing pruritus and PONV, regardless of the method of administration.

Randomized Controlled Trial Comparative StudyRemifentanil halves the EC50 of propofol for successful insertion of the laryngeal mask airway and laryngeal tube in pediatric patients.
Propofol and remifentanil are the drugs of choice for insertion of the supraglottic airway without muscle relaxants for short duration surgery. In this study, we compared propofol concentrations required for insertion of laryngeal mask way (LMA) or laryngeal tube (LT) with and without remifentanil. ⋯ Remifentanil 7.5 ng/mL reduced the propofol concentration required for airway insertion by half, and improved conditions for insertion. Propofol concentrations for insertion of the LMA and LT were similar.

Comparative StudyRapid recovery from sevoflurane and desflurane with hypercapnia and hyperventilation.
Hypercapnia with hyperventilation shortens the time between turning off the vaporizer (1 MAC) and when patients open their eyes after isoflurane anesthesia by 62%. ⋯ Concurrent hyperventilation to rapidly remove the anesthetic from the lungs and rebreathing to induce hypercapnia can significantly shorten recovery times and produce the same proportionate decrease for anesthetics that differ in solubility.
