Study information

Study design	Double-blind randomised active controlled parallel group clinical trial
Primary study design	Interventional
Secondary study design	Randomised controlled trial
Study setting(s)	Hospital
Study type	Treatment
Scientific title
Study acronym	Baringspijn
Study objectives	The hypothesis of this study is that the new opioid remifentanil will provide less side-effects and better pain relief during labour, than the conventional opioids fentanyl and pethidine.
Ethics approval(s)	Received from local medical ethics committee
Health condition(s) or problem(s) studied	Labour pain
Intervention	The following drugs are used in a patient controlled method: 1. Remifentanil - 40 µg for 2 minutes, total dosage: 1200 µg/h 2. Pethidine - loading dose of 50 mg, then 5 mg for 10 minutes, total dosage: 200 mg 3. Fentanyl - loading dose of 50 µg, then 20 µg for 5 minutes, total dosage: 240 µg/h Medication will be started in active labour and will be continued until complete dilation of the cervix is achieved. Baseline non-invasive measurements will be made, including maternal blood pressure, heart rate, respiratory rate and pulse oximetry. Measurements will be recorded every 30 minutes. Also, an observer sedation score will be recorded every 30 minutes.
Intervention type	Drug
Pharmaceutical study type(s)
Phase	Not Specified
Drug / device / biological / vaccine name(s)	Pethidine, remifentanil, fentanyl
Primary outcome measure	1. Quality of pain relief determined by Visual Analogue Scale, patient controlled analgesia (PCA) demands/rewards and the number of patients crossing over to epidural analgesia. Pain scores will be assessed every hour. 2. Patient satisfaction, assessed every hour 3. Foetal outcome as determined by Apgar, NACS and requirement for naloxone, taken after delivery 4. Presence of opioid substances in umbilical and maternal blood samples, taken after delivery
Secondary outcome measures	No secondary outcome measures
Overall study start date	10/08/2005
Completion date	01/09/2006
