Effect of hyperventilation on seizure length during electroconvulsive therapy.
Hyperventilation reportedly prolongs the seizures during eletroconvulsive therapy (ECT) (Bridenbaugh et al. 1972; Holmberg 1953; Holmberg et al. 1956; Weiner 1979; Chater and Simpson 1988). As these studies did not measure the pCO2 concentration it is unclear if prolongation of seizures was due to hyperoxygenation or hypocapnia. In a controlled study Bergsholm et al. (1984) demonstrated an incr...
متن کاملEffect of passive hyperventilation on seizure duration in patients undergoing electroconvulsive therapy.
The influence of end-expired carbon dioxide concentration (E'CO2) on seizure duration was studied in 30 depressed patients undergoing electroconvulsive therapy (ECT) on three separate consecutive occasions. Unpremedicated patients breathed 100% oxygen before the induction of anaesthesia with methohexitone and the provision of partial neuromuscular blockade with suxamethonium. They then received...
متن کاملEffects of Psychotropic Drugs on Seizure Threshold during Electroconvulsive Therapy
OBJECTIVE To analyze the relationship between seizure threshold (ST) and psychotropic drugs in patients treated with ECT. METHODS We examined clinical data from 43 patients. ST was titrated at each treatment session. We examined associations between ST and psychotropic drugs using multivariate correlation analyses. Data are presented as initial ST, the difference in ST between the first and 1...
متن کاملSeizure Threshold in Electroconvulsive Therapy: Effect of Instrument Titration Schedule
Background: Determination of seizure threshold can help guide selection of stimulus dosage in electroconvulsive therapy (ECT); however, this threshold is subject to a variety of influences. Objective: To compare the effect of two stimulus-titration schedules on initial seizure threshold, in 88 patients. Method: One strategy was to use the factory-set stimulus characteristics on the Thymatron DG...
متن کاملSeizure threshold rise during electroconvulsive therapy in schizophrenic patients.
A rise in seizure threshold during a course of electroconvulsive therapy (ECT) has been demonstrated in patients with depression and mania, but no information has been available as to whether the same result occurs in schizophrenia. Ninety-three patients with schizophrenia underwent estimation of the seizure threshold by the dose-titration method, at the first and second, seventh, fourteenth, a...
