Preventative Effect of Combining Dexamethasone with Ondansetron on Postoperative Nausea, Vomiting and Shivering in Children Undergoing Caudal Anesthesia

caudal epidural block is a technique used as an adjuvant to general anesthesia for postoperative analgesia in pediatric patients,especially those with infraumbilical, perineal and lower extremity surgery , because it reduces the need for perioperative and postoperative analgesia, reduces the need for general anesthesia, accelerates the awakening, suppresses the surgical neurohumoral stress response and can be performed easily The objective of the current study is to determine the efficacy and safety of prophylactic intravenous administration of combination of 0.1mg/kg of dexamethasone plus 4mg of ondansetron immediately before establishment of caudal block for prevention of Nausea&vomiting and Shivering in pediatric patients undergoing infra umbilical surgeries

Conditions

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

Although it has some adverse effects: postoperative nausea and vomiting (PONV) are frequent and morbidity-related complication in children, PONV is still present in almost twice the frequency of adults, 33.2-82%. shivering is one of frequent, undesirable adverse effects, The incidence of shivering is up to 40-60% even in regional anaesthesia leads to O2 consumption and CO2 production,So we target in this study two effective drugs with less side effects to reduse these adverse effects Ondansetron is a highly potent selective 5 hydroxytryptamine receptor antagonist, which is widely used as an anti-emetic, Its mechanism of action as anti-shivering is not clear and it is proposed to act centrally at the level of the pre-optic anterior hypothalamic region by inhibition of serotonin reuptake Dexamethasone: is a potent class of steroid drugs ,It prevents thermoregulatory shivering via its central inhibitory effect on the thermoregulatory center and prevents non thermoregulatory shivering by its anti-inflammatory activity, i.e. antagonizing the activation of the inflammatory responses and release of cytokines during surgery The anti-emetic properties of dexamethasone are well established but the mechanisms underlying this anti-emetic effect remain largely unknown

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.

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.
