Randomized Controlled Trial Clinical Trial[Efficacy of ketanserin on postanesthetic shivering].
To evaluate the clinical and electromyographic (EMG) effects of ketanserin (K), a serotoninergic receptor antagonist (5-HT2), on postoperative shivering (POS). ⋯ At a dose of 10 mg, K administered in patients with POS during recovery, reduced significantly the duration and intensity of the shivering without noticeable side effects. This study suggests that this 5-HT2 antagonist is an efficient therapeutic tool for POS in adults.

Review[Evaluation of ischemic repercussions of intracranial hypertension].
The main risk involved in severe intracranial hypertension is, the occurrence of cerebral ischaemia, either locally during herniation or globally as a consequence of reduced cerebral perfusion pressure (CPP). Neurological features of ischaemia occur at a late stage. A continuous monitoring of brain function with EEG or evoked potential techniques, while largely used in the operating room have not been so far fully evaluated in the intensive care setting. ⋯ ICP and CPP monitoring remains the basis for intensive care surveillance during the phase of intracranial hypertension, with alarming settled at admitted critical values (ICP = 30 mmHg; CPP = 70 mmHg). As ischaemic threshold for cerebral blood flow may be different in patients and in normal experimental animals, the reliability of these critical values of ICP and CPP is uncertain. Therefore, transcranial Doppler, jugular metabolic monitoring and, as recently available, cortical tissue PO2 monitoring are mandatory for early detection and assessment of ischaemia.

Review[Treatment of intracranial hypertension in the case of severe craniocerebral injuries].
More than 50% of severely head-injured patients develop increased intracranial pressure, risking exacerbating ischaemic insults to the already injured brain. In approximately 10% of these cases, intracranial pressure may become unresponsive to medical or surgical treatment, with a resulting mortality of over 90%. ⋯ Recently, an algorithm for treating intracranial hypertension under three different therapeutic situations has been suggested, based on the successive application of effective agents with increasing associated risks. Therapeutic modalities of this protocol are discussed.

Clinical Trial Controlled Clinical Trial[Interscalenic block and surgery of the shoulder. A prospective study of a continuous series of 167 patients].
To determine the relationship between minimal stimulating current and success rate of interscalene brachial plexus block (IBPB), to assess the quality of anaesthesia and postoperative analgesia, and to evaluate the benefits and drawbacks of this technique in shoulder surgery. ⋯ The correlation between minimal stimulating current and success rate has clearly shown the benefit of the nerve stimulation. IBPB, which provides a successful and efficient anaesthesia with minimal risk and satisfactory postoperative analgesia, has become the standard technique for shoulder surgery.

Basing on the experience of the Chamonix hospital team which managed in six years 89 cases of hypothermia in trauma patients, this article reviewed the literature concerning the association hypothermia-trauma. Shock is a major triggering factor. The deleterious effects of hypothermia on the outcome is due to inadequate cardiorespiratory adaptation to shock and to increased bleeding. ⋯ It can be more progressive and less invasive in other cases. During recovery from anaesthesia the patient must be closely monitored. In spite of a possible protecting effect, hypothermia remains an aggravating factor in traumatology and must therefore be either prevented or amended.
