[Study of pressor drops during continuous peridural analgesia in gerontologic surgery].
A statistical study bearing upon othe fall of blood pressure concomitant with the setting of peridural anaesthesia was carried out upon an homogeneous series of patients over 75 belonging to groups III and IV of the A S A classification for interventions seating below the IXth metamere. From this study, it seems to follow that: - for starting maximum arterial tensions over 180 mm/Hg, pressure falls are virtually constant in absolute value; - the most important variations in pressure falls are to be found in abdominal surgery; - the lowest figure in blood pressure which accompanies the achievement of surgical analgesia takes place about the 24 th minute whatever the type of surgery can be; - no significant link can be evidence between the importance of the fall in blood pressure and the consumption of the mixture required for surgical analgesia.
