About this study

Official title: Double-blind Randomized Controlled Trial of Caudal Versus Intravenous Dexmedetomidine for Supplementation of Caudal Analgesia in Children

The purpose of this study is to compare the effects of caudal dexmedetomidine with intravenous dexmedetomidine on caudal levobupivacaine analgesia in children undergoing lower abdominal surgeries.

Read the detailed description

Single shot caudal epidural block is one of the most widespread technique for pediatric pain management after infraumbilical surgical procedures.However, in a significant proportion of patients, despite good initial analgesia from a caudal block with local anesthetic, pain develops after the block resolves.

Dexmedetomidine is used increasingly in pediatric anesthesia practice to prolong the duration of action of caudal block with a local anesthetic agent.But which route of administration of clonidine is the most beneficial remains unknown.

The investigators performed prospective randomized double-blind study to compare the effects of caudal dexmedetomidine with intravenous dexmedetomidine on postoperative analgesia after caudal levobupivacaine for inguinal herniorrhaphy or orchidopexy surgery.

90 children (ASAⅠorⅡ,aged 2-5 yr) undergoing unilateral orchiopexy or inguinal herniorrhaphy were included in this study. Anesthesia was induced with sevoflurane via a facemask, followed by placement of a laryngeal mask airway. Anesthesia was maintained with sevoflurane 2-3% in oxygen-air.Then,caudal block was applied. Patients were randomly assigned in three groups. Group Cau-DEX (n = 30): Caudal Levobupivacaine 0.25% 1ml/kg plus dexmedetomidine 1µg/kg and 10 ml normal saline i.v.;Group IV-DEX(n = 30): Levobupivacaine 0.25% 1ml/kg and dexmedetomidine 1µg/kg(10 ml)i.v.;Group Placebo(n = 30): Levobupivacaine 0.25% and 10 ml normal saline intravenous.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Time to first rescue medication

    the Children and Infants Postoperative Pain Scale (CHIPPS)

    Measured: From the administration of the caudal block to the first registration of a CHIPPS scores≥4,assessed up to 24h

Secondary outcomes (6)
  1. the number of patients not requiring rescue analgesia

    the quality of postoperative pain control

    Measured: After surgery,up to 24h

  2. the sedation score

    sedation was assessed using the Modified Ramsay Sedation Score

    Measured: After surgery, every 15min for the first 2 h, every 30min for the next 2h, hourly for the next 4h

  3. Residual motor block

    the degree of motor blockade was assessed using a modified Bromage scale

    Measured: After awake,participants will be followed every 30min for the first 2h, hourly for the next 4h

  4. the incidence of emergence agitation

    The incidence of emergence agitation was evaluated by the Pediatric Anesthesia Emergence Delirium Scale(PAED)

    Measured: Participants will be followed for the duration of PACU stay, an expected average of 2 hours

  5. side effects

    side effects including bradycardia, hypotension, hypoxemia, nausea, vomiting and urinary retention

    Measured: From the administration of the caudal block until the end of study period, assessed up to postoperative 24h

  6. Pain intensity

    Participants will be assessed with Children and Infants Postoperative Pain Scale (CHIPPS)

    Measured: after surgery, 30min for first 4h, hourly for the next 4h and thereafter every 2h,assessed up to 24h

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 15 Nov 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Time to first rescue medication (time frame: From the administration of the caudal block to the first registration of a CHIPPS scores≥4,assessed up to 24h). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01701778, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Nov 2018.
