Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This is a double blind, randomised crossover trial. A single experienced doctor will perform all of the lumbar punctures (LP) under general anaesthesia. A standard LP needle (PORTLAND) will be used. Orientation of the bevel will be parallel to the long axis of the dural fibres. The doctor cannot be blinded to the needle type. All children will be given a sequence of 4 LP's during their treatment for cancer. Twice with each of the 22g and 25g LP needles. Following each procedure, parents will be given a 1 page questionnaire by the RA. The same RA will phone interview them on days 1, 3, and 7 with the same questions. On day 7 more detailed questions will be asked if the patient experiences any headache. These questions will look into issues such as, timing of headache, analgesia required and functional impact on the family.

Sex
Both males and females

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
One large envelope with patient study number, containing four smaller sealed opaque envelopes with study number and procedure A,B,C,D. Research Assistant (RA) provides envelope to proceduralist in order. Needle size concealed from both patient and RA. Staff in theatre are specifically instructed not to discuss needle size allocation with RA or patients.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Computer generated block randomisation (using randomly permuted block sizes). This provides optimal design for most purposes.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
