Effect of IV Infusion of Lidocaine Compared to IV Infusion of

Status Completed

Clinical Trial Summary

This study is designed to compare between intravenous infusion of dexmedetomidine and intravenous infusion of lidocaine in reduction of proinflammatory cytokines as IL-6 and TNF-α, some stress reactions (serum insulin and serum lactate),and postoperative analgesic requirements in patients undergoing surgery for pelviabdominal cancers.

Clinical Trial Description

Cancer patients who undergo surgery face many sources of stress. Surgery causes major cytokine and neuroendocrinal changes like increased levels of catecholamine and steroid hormones and other metabolic consequences .This stress response is considered a defense mechanism important for developing resistance to noxious insults.

The cytokine cascade caused by surgical stimulation is complex with various effects on the injured host. Increased production of proinflammatory cytokines from the site of injury causes many systemic changes such as metabolic derangements and hemodynamic instability. Some released cytokines like tumor necrosis factor alpha (TNF-α) and Interleukin 6(IL-6) can cause long lasting hyperalgesia. These proinflammatory cytokines change pain signal transmission through cytokine induced release of some neuroactive substances like nitric oxide, oxygen free radicals and excitatory amino acids. On the other hand anti-inflammatory cytokines are also released during inflammation to counteract these effects and keep balance.

Dexmedetomidine is a highly selective alpha-2 adrenergic receptor agonist that has sedative, analgesic, anesthetic-sparing properties with no respiratory depression. Its anti-inflammatory effects are being studied.

Intravenous lidocaine can be used in management of chronic pain. Lidocaine has anti-inflammatory properties and is capable of reducing postoperative analgesic requirements and the length of hospitalization.

The effect of both drugs on proinflammatory cytokines and stress response will be assessed ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
