Understanding How Anaesthesia Affects ECT Outcomes

Understanding How Anaesthesia Affects ECT Outcomes

This study will examine how anaesthetic technique affects ECT outcomes. Specifically, the investigators will examine how: 1) the time interval between anaesthetic and ECT stimulus, and 2) the ventilation rate before ECT stimulus, impacts on the quality of the EEG (this is a recording of brain activity during ECT and is used to judge the quality of a seizure and to guide individual patient dosing).

This study aims to examine how the time interval between administration of anaesthetic agent and ECT stimulus delivery impacts upon measures of EEG quality (seizure quality).

Inclusion Criteria:

• Patients treated with a course of ECT

Exclusion Criteria:

• Use of non-standard anaesthetic agents in ECT (e.g. ketamine)
