Trial summary

Effective pain relief after cardiac surgery has assumed importance with the introduction of fast track discharge protocols that requires early weaning from mechanical ventilation. Inadequate pain control reduces the capacity to cough, mobility, increases the frequency of atelectasis, and prolongs recovery. Read more about this study

About this study

Official title: The Analgesic Efficacy of Magnesium Sulfate as an Adjuvant to Continuous Presternal Bupivacaine Infusion Through a Single Catheter After Cardiac Surgery; A Prospective Randomized Double Blind Study.

Effective pain relief after cardiac surgery has assumed importance with the introduction of fast track discharge protocols that requires early weaning from mechanical ventilation. Inadequate pain control reduces the capacity to cough, mobility, increases the frequency of atelectasis, and prolongs recovery. Infiltration of local anesthetics near the surgical wound has shown to improve early postoperative pain in various surgical procedures.

Magnesium is the fourth most plentiful cation in our body. It has antinociceptive effects in animal and human models of pain.

Read the detailed description

Effective pain relief after cardiac surgery has assumed importance with the introduction of fast track discharge protocols that requires early weaning from mechanical ventilation. Inadequate pain control reduces the capacity to cough, mobility, increases the frequency of atelectasis, and prolongs recovery.

A major cause of pain after cardiac surgery is the median sternotomy particularly on the first two postoperative days.

The most often used analgesics in these patients are parenteral opioids which can lead to undesirable side-effects as sedation, respiratory depression, nausea, and vomiting.

Infiltration of local anesthetics near the surgical wound has shown to improve early postoperative pain in various surgical procedures.

Magnesium is the fourth most plentiful cation in our body. It has antinociceptive effects in animal and human models of pain.

It has been mentioned in a systematic review that it may be worthwhile to further study the role of supplemental magnesium in providing perioperative analgesia, because this is a relatively harmless molecule, is not expensive and also because the biological basis for its potential antinociceptive effect is promising.

These effects are primarily based on physiological calcium antagonism, that is voltage-dependent regulation of calcium influx into the cell, and noncompetitive antagonism of N-methyl-D-aspartate (NMDA) receptors.

postoperative pain control will be by 1gm paracetamol / 6 hr, Ketorolac tromethamine 30 mg / 8:12 hour in control group vs bupivacaine 0.125% plus magnesium sulfate 5% through a single catheter after parasternal block in in study group after cardiac surgery.

The investigators primary outcome is pain scores assessment , the secondary outcomes are extubation time, postoperative respiratory parameters, serum cortisol level

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Magnesium Sulfate and Bupivacaine 0.125%Drug

    Also called study

    Each patient will receive bupivacaine 0.125% with 5% magnesium sulphate by infusion through a catheter used for epidural analgesia, positioned presternal.

Study groups in NCT02731950
Study groupRoleWhat they receive
A magnesiumActive comparatorConsists of 20 patients: Each receive bupivacaine 0.125% with 5% magnesium sulfate by infusion through a small diameter multi-hole soft catheter generally used for epidural analgesia positioned anterior to the sternum above the fascia in the subcutaneous tissue during wound closure for 48 hours postoperative. A bolus of 5 ml of the study solution will be injected in the catheter after aspiration test before connection to infusion pump that delivers continuous infusion pump that delivers continuous infusion at a fixed rate of 5 ml/h. postoperative : 25 µg fentanyl for breakthrough pain. placebo will be given in same intravenous instead of paracetamol and ketorolac of group B , to keep the investigator blinded
Receives: Drug: Magnesium Sulfate and Bupivacaine 0.125%
B controlNo interventionConsists of 20 patients: saline as placebo infusion through a small diameter multi-hole soft catheter positioned anterior to the sternum above the fascia in the subcutaneous tissue during wound closure for 48 Postoperative pain control will be managed with 1gm paracetamol /6 hr, Ketorolac 30 mg every 8-12 hour .25 µg fentanyl for breakthrough pain.

What is being measured

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

  1. Pain assessment using a VAS

    Pain score postoperatively on patient's arrival at the ICU, every 4 h for 12 h then every 6 h for 48 h using a VAS (0 = no pain, 10-the worst pain imaginable)

    Measured: up to day 2 postoperative

Secondary outcomes (1)
  1. serum cortisol level

    assessing evening serum cortisol

    Measured: first and second postoperative day

Questions about this trial

What is this clinical trial studying?

A study testing Magnesium Sulfate and Bupivacaine 0.125% in people with Pain and Postoperative Pain, run by Assiut University at 1 site in Egypt.

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 5 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 4 Apr 2017. 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 Egypt. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

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?

Pain assessment using a VAS (time frame: up to day 2 postoperative). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 4 Apr 2017.
