To evaluate the use of inhalational induction followed by intubation through the intubating laryngeal mask (ILM) for patients with severe ankylosing spondylitis undergoing elective surgery who prefer airway management under anesthesia. ⋯ Inhalational induction followed by ILM insertion and blind intubation is a reasonable option in patients with severe ankylosing spondylitis undergoing elective surgery who prefer airway management under anesthesia.
-
To investigate the changes in hemodynamic variables and bispectral index (BIS) in response to a rapid increase in isoflurane or sevoflurane concentration. ⋯ BIS values decrease after a step increase in volatile agent concentration, whether or not a hyperdynamic action occurs.

[Tracheal gas insufflation avoids hypercapnia in patients with severe head trauma and acute lung injury].
The purpose of the ventilatory management of acute respiratory distress syndrome (ARDS) is to avoid any barotrauma to the lungs by decreasing the tidal volume at the expense of permissive hypercapnia. This hypercapnia is extremely dangerous for severe head trauma patients because it increases intracranial pressure. The solution could be the use of tracheal gas which insufflation (TGI) allows the reduction of arterial carbon dioxide tension (PaCO(2)) while controlling airway pressures. ⋯ TGI appears to be an important component of ventilatory management when ARDS is associated with severe head trauma.

To compare the cardiovascular and sympathetic effects of a new ultra-short-acting, highly cardioselective beta- blocker, landiolol, with esmolol, using an in vivo rabbit model. ⋯ These results suggest that, in rabbits, landiolol has slightly more potent negative chronotropic action than esmolol with significantly less effects on blood pressure.

To investigate whether the timing of intrathecal administration of the opioid analgesic fentanyl, alters noxious stimulus-evoked neuronal activity in the rat spinal cord. ⋯ Inasmuch as: 1) c-Fos expression can be equated with behavioural changes; 2) injection of formalin is an appropriate model of surgical trauma; and 3) animal data can be transports to humans, these results suggest that fentanyl would be an effective pre-emptive analgesic.
