Study type
Interventional
Description of intervention(s) / exposure
comparison two doses of suxamethonium in ECT. suxamethonium is a muscle relaxant administered intravenously at the time of ECT to reduce muscle spasms. It will be administered in this way on two consecutive occasions within a week of each other at the time of ECT. On one occassion, the dosage amount of Suxamethonium administered to participants will be 1.0mg/kg
Intervention code [1] 3825 0
Treatment: Drugs
Comparator / control treatment
0.5mg/kg suxamethonium, will be adminsitered intravenously at the time of ECT to act as a muscle relaxant to reduce the amount of muscle spasms. Each dosage amount, 1.0mg/kg and 0.5mg/kg, of Suxamethonium will be administered on only one occassion each
Control group
Active

Outcomes
Primary outcome [1] 5199 0
post procedure myalgia will be assessed by postprocedure questionaire completed by the patient at one hour post procedure
Timepoint [1] 5199 0
at one hour from procedure and at 24hrs via a phone call for the 24hr assessment
Primary outcome [2] 5200 0
degree of fit modification: this is assessed by an observor who will classify how well the fit was modified. A well modified fit with minimal observed spasm is desirable and a less well modified fit with more muscle spasm is undesirable
Timepoint [2] 5200 0
this assessment will take place at the time of the fit and the classification will take place immediately.
Primary outcome [3] 5344 0
the status of myalgia in patients after the procedure. This will be achieved by asking the patient to nominate the degree of myalgia on a four point scale.
Timepoint [3] 5344 0
one hour post procedure and at 24hr post procedure.
Primary outcome [4] 5345 0
the status of myalgia in patients after the procedure. This will be achieved by asking the patient to nominate the degree of myalgia on a four point scale.
Timepoint [4] 5345 0
one hour post procedure and at 24hr post procedure.
Secondary outcome [1] 8753 0
quality of electroencephalogram (EEG) recording. The fit is monitored on the EEG, brain activity, and this is used to assess the adequacy of the fit. A poorly modified fit with significant muscle activity should result in artefact and poor quality recording whereas a well modified fit should result in a higher quality recording with less interference. This will be assessed off line by a blinded psychiatrist who will grade th equality of the recording on a four point scale. recordings will be presented to the assessor in a randomised fashion.
Timepoint [1] 8753 0
this will occur at the completion of the study period and will be blinded.

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
informed consent obtained and patient allocated randomly to receive either dose of suxamethonium then at next treatment with no other alterations they will have the other study dose that they did not receive on the previous ECT. The person enrolling the patient is unaware of which group they will be allocated to. Allocation is by way of 50 sequential numbers with random generation from a computer. . Thereafter this information is contained in sequentially numbered envelopes and the drug will be made up and given to the treating anaesthetist to administer by a second anaesthetist who is not involved in treating the patient
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
list of 50 numbers sequenced randomly by computer. Patients will be allocated to groups based on this

Summary
Brief summary
Patients undergoing ECT often experience postprocedure myalgia. There is also a published range of muscle relaxant doses to minimise this occurrence. It is the purpose of this study to compare the higher and lower recommended doses to see if there is a difference in postprocedure myalgia between the two doses.
