NCT01810406

Brief Summary

Combined spinal-epidurals (CSE) involve the injection of pain relief medication into the cerebral spinal fluid (CSF) and the insertion of an epidural catheter in the epidural space to continue to give pain relief medication. During a CSE, after injection of the medication in the CSF and before inserting the epidural catheter, if normal saline is injected into the epidural space, there may be an increase in pain relief and an increase in the level of numbness. This injection of saline in the epidural space to increase pain relief and numbness is termed epidural volume extension (EVE). The purpose of this study is to determine if there is a benefit for EVE to improve labor analgesia (pain relief) using CSE in pregnant laboring patients.

Eligibility Criteria

Age18 Years+
Sexfemale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Nulliparous parturients requesting regional analgesia for labour pain with singleton, vertex presentation fetuses at 37-42 week gestation in active labor with cervical dilation \< 5 cm.
  • American Society of Anesthesia physical status class I \& II (ASA I - Healthy, ASA II - mild and controlled systemic disease, e.g. controlled essential hypertension)
  • Age ≥ 18 years (Standard within the obstetrical anesthesia literature)
  • English-speaking

You may not qualify if:

  • Contraindications to neuraxial analgesia (i.e. coagulopathy, systemic infection, neuropathy)
  • Conditions associated with abnormal spinal anatomy which can affect local anesthetic spread (i.e. scoliosis, spina bifida, spinal instrumentation)
  • Conditions associated with an increased risk of a cesarean delivery (i.e., history of uterine anomaly or surgery, morbid obesity (Body Mass Index ≥ 35 kg/m2)
  • Clinically significant diseases of pregnancy such as pregnancy-induced hypertension or preeclampsia (defined as systolic blood pressure (SBP) \> 160mmHg, diastolic blood pressure (DBP) \> 110mmHg and/or requiring antihypertensive treatment or associated with significant proteinuria)
  • Severe maternal cardiac disease
  • Known fetal anomalies /intrauterine fetal demise
  • Patient enrollment in another study involving a study medication within 30 days
  • Any other physical or psychiatric condition which may impair their ability to cooperate with study data collection
