[Duration of anesthesia and mode of administration of Diprivan].

The dosage regimen to maintain propofol anaesthesia should ensure adequate depth of anaesthesia for the procedure, and allow a swift recovery. If the dosage is not adapted to the various phases of surgery, there is a risk of awareness especially after painful stimuli. This awareness is not always announced by signs which would allow its prevention.

[Removal of wasted endocavitary pacemaker electrodes by the epigastric route without cardiopulmonary bypass (author's transl)].

Wasted, embedded and infected endocavitary pacemaker electrodes responsible for severe septicaemia were removed on three occasions, using an original technique. The heart was approached through a subxyphoid or epigastric incision, and the right ventricule was entered through a short opening in its diaphragmatic surface. The cardiac incision was comprised within a U-shaped suture resting on two teflon felter strips.
