Further study details as provided by Christian von Heymann, M.D., Charite University, Berlin, Germany:

Primary Outcome Measures:
  • Postoperative pain levels during movement (cough) [ Time Frame: At nine hours after the end of surgery (closure time) ]
    Patient self-assessed postoperative pain levels during movement (cough) using an unmarked zero to one hundred mm visual analog scale (VAS)


Secondary Outcome Measures:
  • Postoperative pain levels during rest [ Time Frame: At nine hours after the end of surgery (closure time) ]
    Patient self-assessed postoperative pain levels during rest using an unmarked zero to one hundred mm visual analog scale (VAS)

  • Postoperative pain levels during rest and movement [ Time Frame: At zero (injection), one, two, six, nine, twenty four, fourty eight hours after the end of surgery (closure time) ]
    Patient self-assessed postoperative pain levels during rest and movement using an unmarked zero to one hundred mm visual analog scale (VAS)

  • Change of type of anesthesia when regional anesthesia fails [ Time Frame: During the operation ]
  • Level of anesthesia during the operation [ Time Frame: During the operation ]
  • Incidence of hypotensions during the operation [ Time Frame: During the operation ]
  • Sedation level (Ramsay-Score) [ Time Frame: Postoperative course ]
  • Capability for mobilisation and time to first mobilisation [ Time Frame: Postoperative course ]
  • Incidence of adverse reactions (PONV, headache and backpain, urinary retention) [ Time Frame: Postoperative course ]
  • Satisfaction with pain management [ Time Frame: Postoperative course ]
  • Co-analgesics [ Time Frame: In the 48-hour postoperative sample period ]
    Co-analgesic consumption

Arms Assigned Interventions
Active Comparator: Group 1
Spinal anesthesia + intrathecal opioid bolus (SPA)
Procedure: SPA
Spinal anesthesia and opioids
Active Comparator: Group 2
CSE + epidural opioid bolus (CSE)
Procedure: CSE
CSE and epidural opioids
Experimental: Group 3
CSE + continuous epidural patient controlled analgesia using an epidural catheter for 24 hrs (CSEPCEA)
Procedure: CSEPCEA
CSE and continuous epidural patient controlled analgesia using an epidural catheter for 24 hrs

Detailed Description:

Regional analgesia is the most effective way of providing analgesia during labor and delivery. By using a combination of local anesthetics and opioids, it is often possible to avoid motor block. Spinal anesthesia is suitable for most elective cesarean sections. Epidural anesthesia and in particular catheter based epidural anesthesia allow a gradual extension of anesthesia and are suitable for prolonged treatment of postoperative pain.

It is unclear which anesthetic technique provides better pain relief after cesarean section.

This prospective, randomized study compares the effectiveness of three types of regional anesthetic techniques (Spinal anesthesia, Combined spinal epidural anesthesia, Combined spinal epidural anesthesia with indwelling catheter for 24 hrs) on pain after elective cesarean section.
