About this study

Official title: Comparison of the Efficacy of Intravenous Dexmedetomidine and Tramadol in Control of Post Spinal Shivering in Obstetric Patients Undergoing Lower Segment Cesarean Section

When opposed to GA,SA is recommended during c section. Shivering is more prevalent and inconvenient complication of spinal anaesthesia, with 40 to 70% incidence rate. Tramadol has been proven to be beneficial in preventing post spinal shivering. Dexmedetomidine is a sedative, analgesic, anxiolytic, sympatholytic and opioid-sparing alpha adrenergic agonist. It has been shown to lower the threshold for shivering. The study aims to search for best drug for blunting shivering response.

Read the detailed description

When opposed to general anaesthesia (GA), spinal anaesthesia (SA) is recommended during caesarean section (CS) because of various advantages, including the prevention of GA-related neurotoxicity, its early onset and ease of administration, and the reduction of post-operative pain. Intraoperative shivering is the most prevalent irritating and inconvenient complication of spinal anaesthesia, and it is a very distressing experience that causes physiological stress to both patients and perioperative physicians and operating surgeons. Shivering is a skeletal muscular movement that occurs involuntarily and repeatedly. It's a common post-anesthesia adverse effect, with a 40-70% incidence rate.Shivering is not only physically unpleasant for the sufferer, but it can also have several negative consequences. It can cause pain, and discomfort for patients, obstruct monitoring techniques, raise intraocular and intracranial pressures, and double or even triple oxygen and carbon dioxide intake.Various pharmacological and non-pharmacological strategies for managing intraoperative shivering are discussed.

Tramadol, a centrally acting analgesic with -opioid agonist properties and little action on kappa and delta receptors, has been proven to be beneficial in preventing post-spinal shivering. The method of action is thought to be through a modulatory influence on central monoaminergic pathways, which inhibits noradrenaline and serotonin neuronal absorption in the spinal cord while boosting hydroxyltryptamine production, resetting the body temperature regulatory center.However, it has many side effects, including nausea, vomiting, and dizziness, which add to the patient's pain. Hence research into novel solutions with adequate safety and effectiveness is strongly advised. In this sense, despite taking into account the gold standard for post spinal shivering control is pethidine. it is contraindicated in breastfeeding which is both legally and ethically challenging for women.

Dexmedetomidine is a sedative, analgesic, anxiolytic, sympatholytic, and opioid-sparing alpha 2 adrenergic agonist with good selectivity and specificity.It has been shown to lower the threshold for shivering.Dexmedetomidine does not affect the locus ceruleus of the spinal cord, and it does not cause respiratory depression. In postoperative patients, dexmedetomidine lowers cortisol and norepinephrine levels, as well as blood glucose, interleukin (IL)-6, tumour necrosis factor-a, and C-reactive protein, and raises interleukin-10. Moreover, because Dexmedetomidine does not affect upper airway reflexes, it is an excellent option.It was believed that the sedative impact of intravenous injection on newborn infants was very minimal and could be disregarded due to the delayed sedative effects.

These drugs have well-defined roles to blunt the "shivering response" and hence have been used in different comparative studies to develop the single best drug of choice. Yet, there is no consensus over a single drug. In our research, we intend to compare IV Tramadol and IV Dexmedetomidine for controlling post spinal shivering in obstetric patients. The study aims to search for the best drug for blunting the shivering response, which may prove fatal in any patient.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Dexmedetomidine injection and Tramadol in people with Post Spinal Shivering, run by Sana Bahadur.

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 7 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: status not confirmed, as of the sponsor's last update on 15 Nov 2022. Status can change between updates, so confirm with the study contact before making plans.

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.

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?

Results are not available in the source record.

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?

Assessment of post spinal shivering by observing grades of shivering (time frame: 10 minutes). 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 15 Nov 2022.
