Maternal intra-partum fever commonly complicates the process of labour. Its occurrence is often regarded as being synonymous with the presence of chorioamnionitis. This inevitably results in the administration of antibiotics to the affected mother. Review of the literature however suggests that this approach is not always appropriate. Non-infective causes of this condition that are often overlooked include the use of epidural analgesia for pain relief, normal thermal physiological changes in women not using any form of analgesia and delivery in an overheated room. Women with certain risk factors such as nulliparity and a long latent phase of labour are also more prone to developing maternal intra-partum fever. Irrespective of its aetiology, maternal intra-partum fever carries risks both for the mother and her unborn child. Putting more thought into the care of these patients will go a long way in reducing the maternal and neonatal morbidity associated with this complication.The combined spinal-epidural (CSE) technique has been introduced in an attempt to reduce these adverse effects. CSE is believed to during labour provide more rapid onset of analgesia than epidural analgesia, The incidence of fever is significantly lower with CSE technique.

Further study details as provided by Instituto Materno Infantil Prof. Fernando Figueira:

Primary Outcome Measures:
  • Fever frequency [ Time Frame: each hour ]
    We will measure the temperature each hour

Secondary Outcome Measures:
  • Incidence of c-section and instrumental delivery [ Time Frame: within the delivery ]
    Will measure the instrumental delivery when the CSA technique is used

Enrollment: 70
Study Start Date: January 2010
Study Completion Date: June 2010
Primary Completion Date: June 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: Massages baths
doulas, massages and baths
Active Comparator: Combined spinal-epidural anesthesia
local anesthetics in low doses with opioids
Drug: Combined epidural and spinal anesthesia
Obstetrics patients will relieve spinal anesthesia with local anesthesics and opioids associated with epidural anesthesia with local anesthetics in low concentrations with opioids
Other Names:
  • Local anesthetics
  • spinal opioides

Detailed Description:

The objective this study is determine the fever maternal incidence with CSE technique for labor analgesia.

METHODS: a randomized open clinical trial will be conducted involving Seventy healthy, term, nulliparous women in spontaneous labor were assigned to either CSE technique or non pharmacologic analgesia for labor.these patients will be randomly assigned to receive or not CSE technique for labor analgesia. Outcomes analysis wiil include maternal fever, pain intensity measured by visual analog scale, labor duration, c-section and instrumental delivery. statical analysis will performed using Mann-Whitney and Fisher" exact test 5% level of significance.
