Randomized Controlled Trial Clinical TrialUnilateral spinal anaesthesia with hyperbaric bupivacaine.
The dosage of local anaesthetic and the time the patient must be kept in the lateral decubitus position for a unilateral spinal anaesthesia is not known. The aim of this study was to determine the ideal dosage of hyperbaric bupivacaine and the time required for the lateral decubitus position for a unilateral spinal block. ⋯ For unilateral spinal anaesthesia in lower extremity operations, 2ml 0.5% hyperbaric bupivacaine solution for operations above the knee and 1.5 ml 0.5% hyperbaric bupivacaine solution for operations below the knee and keeping the patients for 10 min in the lateral decubitus position were found to be appropriate.

Randomized Controlled Trial Clinical TrialSurgeon's experience as a factor for emetic sequelae after middle ear surgery.
To test the hypothesis that an experienced surgeon is associated with less postoperative nausea and vomiting (PONV). ⋯ The patients operated by residents need more aggressive prophylaxis for PONV than those operated by specialists in middle ear surgery.

Responses of respiratory drive and breathing pattern to inspiratory loading during nitrous oxide and isoflurane sedation.
Increased inspiratory resistance in combination with mild gas narcosis is common during recovery after a general anesthesia, but there are only few previous studies on inspiratory loading during subanesthetic gas narcosis. ⋯ It is concluded that the steady-state ventilatory responses to loading, consisting of increased P0.1 and decreased VT, are maintained during inhalation of subanesthetic doses of N2O (0.13-0.38 MAC) and isoflurane (0.09-0.26 MAC).
