Antiemetic efficacy of propofol at small doses for reducing nausea and vomiting following thyroidectomy.

To determine the ability to predict difficult visualization of the larynx (DVL) from the following preoperative airway predictive indices, in isolation and combination: modified Mallampati test (MMT), thyromental distance (TMD), sternomental distance (SMD), horizontal length of the mandible (HLM) and inter-incisor gap (IIG). ⋯ MMT, TMD and IIG appear to provide the optimal combination in prediction of DVL in a West African population.

To evaluate neurostimulation of motor components of the vastus medialis muscle and the rectus femoris muscle, with a view to blocking the medial sensory fibres of the saphenous nerve. ⋯ Neurostimulation of the vastus medialis muscle has the same effect as neurostimulation of the rectus femoris muscle with respect to anesthesia of the saphenous nerve. Neurostimulation of the medial compartment of the femoral nerve saves local anesthetic, compared to a standard femoral block.

Randomized Controlled Trial Clinical Trial
Landiolol attenuates tachycardia in response to endotracheal intubation without affecting blood pressure.
Beta-adrenergic receptor antagonists (beta-antagonists) have long been used to control perioperative tachyarrhythmias. The effects of a beta(1)-antagonist, landiolol, on perioperative hemodynamics are unknown. We aimed to determine the appropriate dosage of landiolol for the treatment of hemodynamic changes in response to endotracheal intubation. ⋯ The newly developed beta(1)-antagonist landiolol (0.1 and 0.3 mg.kg(-1)) may help prevent tachycardia without affecting blood pressure during the induction of anesthesia.
