Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Women presenting for emergency caesarean section (E1-E3) will be randomised to one of two groups, and either receive intrathecal pethidine 10mg with bupivacaine, or intrathecal fentanyl 10mcg with bupivacaine. Our hypothesis is that women receiving pethidine will experience less shivering than those receiveing fentanyl.
The intervention will last four hours only.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The syringe containing the opiate will be prepared by the hospital pharmacy. The syringes for both groups will appear identical. The syringes will be numbered 0-40 by pharmacy. Pharmacy will randomly number the syringes (computer generated). The anaesthetic nurse will randomly choose a syringe from a box containing the syringes.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Computer generated. No restriction.
Masking / blinding
Blinded (masking used)
