A prospective study comparing initial electroconvulsive therapy treatment doses determined by empirical dose titration with estimates derived from two simple dose prediction methods and a fixed-dose regimen (275 mC).
Thirty-three patients had seizure thresholds between 25 mC and 403 mC. The dose titration method led to a mean initial treatment dose of 195 mC that was intermediate between those predicted by the age method (275 mC) and the half-age method (137 mC). Estimates were within acceptable limits in 33% of cases for the age method, 64% for the half-age method and 40% for the fixed-dose method.
Either dose prediction or dose titration methods may be more appropriate in different clinical situations. The half-age method appears to be a more accurate predictor of optimum initial treatment dose.
A randomised, blind comparison of a structured consent procedure against routine consent was conducted to determine whether it had any utility in improving treatment knowledge In patients receiving electroconvulsive therapy (ECT). Additionally we aimed to determine whether degree of cognitive impairment intelligence and severity of depression influenced recall of information.
Thirty-two subjects were investigated. Structured consent significantly improved the number of knowledge items recalled pre-ECT (P<0.05). Knowledge scores declined significantly after completion of the treatment course in both structured consent (P<0.05) and control groups (P<0.06). There was a significant correlation between Mini-Mental State Examination (MMSE) scores and the number of knowledge items recalled both pre- (r=0.43, P<0.05) and post-ECT (r=0.53, P<0.01).
Structured consent procedures may be a useful way of improving patient knowledge of ECT and merit further study. Low scores on MMSE should caution clinicians to take particular care when consenting patients to ECT.
Recently developed magnetic polarity stratigraphies in the western South–Central Unit provide a more-precise temporal database for the analysis of the depositional and deformational history of the southern Pyrenean foreland basin. When combined with lithostratigraphic and structural data, the eight new magnetic sections along the Isabena and Esera valleys and in the Ainsa Basin help define the early stages of development of the Eocene foreland and illustrate the important role played by growing structures, such as the Mediano Anticline, in controlling depositional environments and patterns of subsidence.
In an attempt to develop more precise chronological control for the depositional and deformational history of the central part of the South Pyrenean fold-and-thrust belt and its related foreland-basin deposits, several new magnetic polarity stratigraphies have been developed within the syntectonic sedimentary succession. The temporal information derived from these studies permits more detailed correlation between sections and more reliable analysis of the timing, sequencing and rates of sedimentary and tectonic processes. This work has been focused on the western part of the South–Central Unit (Séguret, 1972) and encompasses the western Tremp–Graus and Ainsa basins (Fig. 1). Whereas the majority of these studies has been concerned with late Eocene and Oligocene deposition, part of the studied record begins in the early Eocene. We report here the data and the location of each magnetostratigraphic section, the nature of the magnetic record from these sites, the chronologic significance of each section, and some of the geologic conclusions drawn from these chronologic data.
