Techniques for Perioperative Analgesia for Live Liver Donors; A Pilot Study

January 8, 2018 updated by: Rasha Samir Abd-ElWahab Bondok, Ain Shams University

A Pilot Study for a Prospective, Randomized Controlled Trial of Techniques for Perioperative Analgesia for Live Liver Donors

This study,will evaluate the efficacy of ultrasound (US)-guided subcostal oblique TAP block together with IV infusion of Dexmedetomidine and fentanyl as a type of multimodal analgesic regimen in comparison with IV fentanyl based analgesia only in live liver donors.

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Total fentanyl consumption
Time Frame: Intraoperative
Total Intravenous fentanyl consumption during the operation
Intraoperative

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Average sevoflurane concentration
Time Frame: Intraoperative
The average sevoflurane concentration (the average concentration (%) for the case will be determined from the vaporizer setting recorded in the anesthetic record per 5-minute interval)
Intraoperative
The severity of postoperative nausea and vomiting (PONV)
Time Frame: First 24 hours postoperatively
Will be recorded and classified as "no PONV, mild PONV, moderate PONV and severe PONV"
First 24 hours postoperatively
Ramsay sedation score (RSS)
Time Frame: First 24 hours postoperatively
Will be used for assessment of sedation immediately after extubation, after 2 hours of ICU admission, after 12 hours then after 24 hours .
First 24 hours postoperatively

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
