Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Study Objective: To assess the analgesic efficacy of diclofenac or ropivacaine when administered via wound infusion.

Design: Prospective, randomized, double-blind, placebo-controlled study. Setting: Large referral hospital. Patients: 75 women recovering from Cesarean section performed via a Pfannenstiel incision.

Interventions: On completion of the surgical procedure, a 15 cm 19G infusion catheter (PAINfusor™, Baxter) will be placed below the fascia. According to a computer generated randomization schedule, patients will be divided into one of three treatment groups (n = 25).

  • In Group Control water for injection will be administered.
  • In Group Ropivacaine 0.2 % ropivacaine will be administered.
  • In Group Diclofenac diclofenac (300 mg/240 ml of water for injection) will be administered.

During the first 6 postoperative hours, a co-investigator will administer "rescue" analgesia (10 ml bolus of infusion drug or rescue morphine). Thereafter, the catheter will be connected to an elastometric pump (LV 10 Infusor, Baxter) filled with either water for injection, ropivacaine 0.2 %, or diclofenac (300 mg/240 ml water for injection). The fluid will be administered as a constant infusion rate (10 mL/hr). Continuous wound infusion will be continued for the subsequent 18 postoperative hours. During this 18 hour period, subcutaneous morphine 4 mg will be administered on patient request for additional analgesia.

Measurements and Main Results: The following parameters will be assessed and recorded:

  1. Demographic data
  2. Surgical milestones(Anesthetic time, surgical time etc).
  3. Incidence of failed intrathecal anesthesia
  4. VAS for pain every 15 min during first 6 postoperative hours
  5. Time to first pain (intrathecal anesthesia to VAS > 60 mm)
  6. Number of infusion events (10 mL and 5 mL)
  7. Rescue morphine administration during first 6 postoperative hours.
  8. Subcutaneous morphine administration during subsequent 18 postoperative hours.
  9. VAS for pain.
  10. The incidence of nausea and vomiting.
  11. Patient satisfaction at 24 hours, postoperatively.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
