Brief Summary:
The study was primarily designed to assess the role of acupuncture in reducing the need for epidural analgesia for pain relief during induced labour. The other outcomes of labour were to be observed in addition.

Condition or disease Intervention/treatment Phase
Pain Procedure: acupuncture Not Applicable

Detailed Description:
The study was limited to women in their first pregnancy having labour induced for prolonged pregnancy or mild hypertension. The study involved randomised groups managed with manual acupuncture, electro acupuncture, sham acupuncture and a no-treatment control group.

Arm Intervention/treatment
Experimental: manual acupuncture
Sterile needles were inserted intramuscularly to a depth of 15-20mm until an unusual (De-Qi) sensation developed and remained inserted for 30-60 minutes and were manually manipulated during this time. The following bilateral acupoints on the hands and feet at Hegu (LI 4), Sanyinjiao (Sp 6) Kunlun (BL 60) and Zhiyin (BL 67)were used.
Procedure: acupuncture
The description of the acupuncture, whether manual, electro or sham, is as described for each of the individual groups.
Other Names:
  • Disposable needles Seirin DN04 0.20x30mm - 0.30x50mm.
  • Electronic Acupunctuscope AWQ-104L digital.
Experimental: electro acupuncture
Sterile needles were inserted intramuscularly to a depth of 15-20mm until an unusual (De-Qi) sensation developed and remained inserted for 30-60 minutes and were either electronically simulated withm2 Hz pulses of 0.5 msec duration for 30 minutes sufficient to cause non-painful muscle contractions. The following bilateral acupoints on the hands and feet at Hegu (LI 4), Sanyinjiao (Sp 6) Kunlun (BL 60) and Zhiyin (BL 67)were used.
Procedure: acupuncture
The description of the acupuncture, whether manual, electro or sham, is as described for each of the individual groups.
Other Names:
  • Disposable needles Seirin DN04 0.20x30mm - 0.30x50mm.
  • Electronic Acupunctuscope AWQ-104L digital.
Sham Comparator: Sham manual or electro acupuncture
Sterile needles were inserted adjacent to the specific acupuncture sites identified for the manual and electro groups to a depth of 1-1.5mm only and insufficient to provoke an unusual sensation and left in position for a 30-60 minutes. Those randomised to 'sham-manual' received no stimulation and those randomised to 'sham-electro' were connected to the electrical stimulator but the current not activated.
Procedure: acupuncture
The description of the acupuncture, whether manual, electro or sham, is as described for each of the individual groups.
Other Names:
  • Disposable needles Seirin DN04 0.20x30mm - 0.30x50mm.
  • Electronic Acupunctuscope AWQ-104L digital.
No Intervention: control group
Following randomisation to be control group, no specific treatment was organised at this time.
Procedure: acupuncture
The description of the acupuncture, whether manual, electro or sham, is as described for each of the individual groups.
Other Names:
  • Disposable needles Seirin DN04 0.20x30mm - 0.30x50mm.
  • Electronic Acupunctuscope AWQ-104L digital.
