A study into predictors for the speed of response to electroconvulsive therapy.

The efficacy of electroconvulsive therapy (ECT) has been firmly established in the treatment of depression. However, prediction of the speed of response to ECT is an issue that needs to be further explored. This study aims to examine the presence of predictors for the speed of response. In a retrospective chart review using 57 patients suffering from major depression who received ECT, the relation of several patient and ECT variables with the speed of response was explored. Response was defined as a drop of at least 35% in Hamilton rating scale of depression (HRSD) score from baseline after 3 or 4 ECT sessions. Patients received ECT with an aged-based stimulus dosage in a clinical setting. Multiple regression analysis showed that high baseline HRSD score and high seizure energy index (SEI) were significantly and independently associated with a rapid response. In a regression model, baseline HRSD score and SEI can be used to predict the speed of response to ECT. Rapid responders to ECT achieved remission significantly more often than slow responders did. SEI can be modified by the clinician. This offers the possibility to optimize ECT treatment.

Effects of maintenance electroconvulsive therapy on cognitive functions.

BACKGROUND: This study examined cognitive side effects of maintenance electroconvulsive (ECT) in comparison with maintenance pharmacotherapy after index ECT. METHOD: Clinical outcome data and neuropsychological measurements were compared in 11 maintenance ECT patients and 13 control patients treated with maintenance pharmacotherapy after index ECT. Data were gathered in a prospective naturalistic study during follow-up. RESULTS: There were no significant differences in patient characteristics and effects of index ECT between groups. In control patients treated with maintenance pharmacotherapy, cognitive function as well as depression ratings remained stable. During maintenance ECT neuropsychological test performance and depression ratings improved slightly but not significantly. CONCLUSIONS: Neuropsychological functioning during the maintenance phase of treatment did not differ between the two treatment groups. Cognitive function remained stable during maintenance ECT.

Training in the management of critical problems: teacher's view.

Teaching in critical obstetric problems should have special interest during residency and thereafter. Obstetric emergencies are relatively rare but may occur at any time. The obstetrician at that moment enters a special area requiring a multidisciplinary approach. From experiences in recent years and study of the literature the following recommendations can be summarized; (1) the need to understand (patho)physiologic changes in pregnancy, (2) cultivation of an anticipative attitude towards conditions with elevated risks, (3) adequate knowledge of diagnostic procedures, (4) the discipline to make a differential diagnosis, (5) experience with monitoring of (fetal and) maternal condition, (6) availability of management protocols for emergencies such as shock, eclampsia, uterine rupture, amniotic fluid embolism, thrombo-embolism, sepsis and diabetic ketoacidosis, (7) awareness of pitfalls with inspection of lesions and assessment of blood loss, (8) awareness that caesarean section without prior stabilization can be a life threatening procedure, (9) practice in life-saving measures such as uterine compression, packing, ligation of vessels, postpartum hysterectomy, (10) teaching of postoperative care, (11) insight into the cascade of events finally leading to multi-organ failure. Obstetric emergencies require a disciplined approach, in which teamwork is the cornerstone.
