Recall of awareness during cardiac anaesthesia: influence of feedback information to the anaesthesiologist.
We interviewed 303 cardiac surgery patients to evaluate the incidence of intraoperative awareness with recall. First, we randomly interviewed 99 patients, of whom four patients (4%) reported awareness and recall. We informed the cardiac anaesthesiologists of the results of these interviews, and we also gave general information regarding means to reduce awareness and recall during general anaesthesia. ⋯ The patients with awareness were significantly younger than those not aware. In conclusion, with educational measures and vigilance over the problem, the incidence of intraoperative awareness during cardiac anaesthesia may be reduced. The incidence figure of 1.5% we observed is of the magnitude reported recently by others with modern cardiac anaesthesia techniques.

Propofol anaesthesia in spontaneously breathing paediatric patients during magnetic resonance imaging.
The aim of this study was to evaluate the use of propofol to induce and maintain anaesthesia in spontaneously breathing paediatric patients (age 2 weeks-11 years) during Magnetic Resonance Imaging (MRI) of the CNS. ⋯ Propofol can be safely used for total intravenous anaesthesia in children undergoing MRI.

Gastric emptying of a light hospital breakfast. A study using real time ultrasonography.
While intake of clear fluids 2-3 h before surgery is considered safe as it does not influence gastric content, it is not known if the same applies to a light breakfast meal. We therefore studied gastric emptying of a light breakfast in healthy, female volunteers without evidence of gastrointestinal motility disorders. The test meal consisted of one slice of buttered toast with jam, one cup of coffee without milk or sugar and one glass of pulp-free orange juice taken together with a paracetamol mixture. ⋯ The gastric antral area returned to fasting value significantly faster than the disappearance of solid particles; median 150 min versus 210 min; P = 0.01. Our results show that in healthy subjects the stomach cannot be considered empty for solid particles the first 4 h after a light breakfast meal. To secure some safety limits, we suggest a 6-h mandatory preoperative fast after a light breakfast.
