Text: Satisfaction was higher in group 2 mothers (median group difference +3 mm, 95 % confidence interval +1 to +5, p = 0. 012) : this was associated with more normal deliveries (difference between proportions 0. 23, 95 % confidence interval +0. 03 to +0. 42) ; greater self control (median group difference -7 mm, -17 to -2, p = 0. 003) ; and reduced unpleasantness of motor blockade (-10 mm, -19 to -5, p less than 0. 001), sensory blockade (-5 mm, -11 to -2, p = 0. 002) and shivering (-5 mm, -18 to 0, p = 0. 046) at the expense of mild itching (0 mm, 0 to 0, p less than 0. 001).
