Brief summary
We will test to see if the addition of sterile water injections for the relief of back pain in labour to standard pharmacological (nitrous oxide gas, narcotics, epidural) and non-pharmaclogical analgesic options ( shower, water immersion, massage, heat, aromatherapy, TENS) will affect birth outcomes, specifically the rates of caesarean section.
Interventions
Women with back pain during first stage labour, assessed by visual analogue scale as = 7 will receive 0.1 – 0.3 millilitres of sterile water for injection. The exact volume injected is determined by visualisation of the resulting blister or bleb by the administering clinician. The injection is given using of one-millilitre syringes and 23 gauge needles, one injection into four anatomical points surrounding the Michaelis rhomboid over the sacral area: two over the posterior superior iliac spines (PSIS) and the remaining two at two centimetres posterior, and one centimetre medial, to the PSIS respectively. Women may receive repeat injections upon request once the VAS is again = 7. Repeat injections will be of Sterile Water for injection. There is no maximum amount of injections that women may receive during their labour.
