BACKGROUND The Valsalva manoeuvre is an internationally recommended treatment for supraventricular tachycardia, but cardioversion is rare in practice (5-20%), necessitating the use of other treatments including adenosine, which patients often find unpleasant. We assessed whether a postural modification to the Valsalva manoeuvre could improve its effectiveness. METHODS We did a randomised cont...

INTRODUCTION Lung collapse is a contributory factor in the hypoxaemia that is observed after open endotracheal suctioning (ETS) in patients with acute lung injury and acute respiratory distress syndrome. Lung recruitment (LR) manoeuvres may be effective in rapidly regaining lung volume and improving oxygenation after ETS. MATERIALS AND METHOD A prospective, randomized, controlled study was co...

Knowledge of the level of pharyngeal obstruction during sleep is an important factor in deciding whether or not a patient suffering from obstructive sleep apnoea syndrome (OSAS) will benefit from uvulopalatopharyngoplasty. The Muller manoeuvre has been advocated as a method of obtaining this information. We compared the findings from the technique of sleep nasendoscopy, which actually allows vi...

A sump system was used as a palliative manoeuvre in the treatment of four cases of cystic craniopharyngioma. Percutaneous needling of the subcutaneous reservoir enabled the fluid contents of the tumour to be evacuated with considerable therapeutic effect. Radiotherapy was combined with this manoeuvre in two cases. The three successfully treated patients have been followed up for 3 1/2, five, an...

The facilitating effect of the Jendrassik manoeuvre on monosynaptic reflexes in man has been studied by comparing H and T reflexes of the soleus and by blocking the effects of spindle activation by ischaemia of the leg. The Jendrassik manoeuvre equally enhances H and T reflexes provided that the test reflexes are small. The H reflex remains facilitated when the spindle activation cannot affect ...

A major cause of impaired gas exchange during general anaesthesia is atelectasis, causing pulmonary shunt. A 'vital capacity' (VC) manoeuvre (i.e. inflation of the lungs up to 40 cm H2O, maintained for 15 s) may re-expand atelectasis and improve oxygenation. However, such a manoeuvre may cause adverse cardiovascular effects. Reducing the time of maximal inflation may improve the margin of safet...

Cardiovascular responses to the Valsalva manoeuvre were examined in 19 non-diabetic subjects and 32 diabetic patients, some with signs of autonomic dysfunction. All the non-diabetic subjects showed an overshoot in systemic arterial pressure and a bradycardia after the manoeuvre, and in 11 of them only forearm vasoconstriction occurred. However, in eight non-diabetic subjects a forearm vasodilat...

The inhibitory effects of acute pain produced by the Lasègue's manoeuvre on the lower limb nociceptive flexion reflexes induced by electrical sural nerve stimulation were explored in patients complaining of sciatica as a result of an identified unilateral disc protrusion. Lassègue's manoeuvre on the affected side produced a typical radicular pain and resulted in a powerful depression of nocicep...
