Effects of sufentanil or ketamine administered in target-controlled infusion on the cerebral hemodynamics of severely brain-injured patients.

Objective: The manual injection of a bolus of opioid in patients with brain injury induces an increase in intracranial pressure related to a decrease in mean arterial pressure. Such an effect has not been observed with the use of ketamine. The use of target-controlled infusion would minimize or suppress this adverse effect of opioid.

[Do we have to monitor foetal heart rate during general anesthesia?].

We present a case of an emergency Caesarean section due to misinterpretation of the cardiotocography (CTG) trace during general anaesthesia for treatment of dental abscess. Following failure of the dental abscess treatment under local anaesthesia, a 29-year-old female in the 36th week of a twin pregnancy was to undergo general anaesthesia. Foetal well-being was monitored with ultrasonographic evaluations of foetal heart rate.

The effects of remifentanil on endotracheal suctioning-induced increases in intracranial pressure in head-injured patients.

In patients with severe traumatic brain injury, bronchotracheal toilet may be accompanied by deleterious variations in intracranial pressure (ICP). To avoid these effects, IV opioids have been proposed. Twenty mechanically-ventilated patients received 3 ascending IV doses of remifentanil: dose 1 (1 microg/kg bolus, 0.

Target concentrations of remifentanil with propofol to blunt coughing during intubation, cuff inflation, and tracheal suctioning.

Background: The target blood concentrations of propofol and remifentanil, when used in combination, required to blunt the cough response to tracheal intubation, cuff inflation, and tracheal suctioning without neuromuscular blocking agents are not known.

Methods: In a randomized prospective study, 81 patients were enrolled to determine which of three target remifentanil blood concentrations was required to blunt coughing during intubation, cuff inflation, and tracheal suctioning. Anaesthesia was achieved with propofol at a steady effect-site concentration of 3.
