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.

Study Contact

The name and contact information for the person who can answer enrollment questions for a clinical study. Each location where the study is being conducted may also have a specific contact, who may be better able to answer those questions.

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
The time to first rescue analgesic
Time Frame: 24 hours postoperative

The duration between the administration of spinal block and the first desire for supplemental analgesia (onset of 1st post-operative analgesic dose).

First post-operative analgesic dose will be1 μg/kg intravenous fentanyl when visual analogue pain score (VAS) is 4 or more
24 hours postoperative

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
Postoperative pain score Total dose of analgesic consumption I the first postoperative day Intraoperative and postoperative complications
Time Frame: 24 hours postoperative
Visual analogue score (VAS) between 0 and 10{0= no pain, 10=most severe pain}
24 hours postoperative
Total analgesic consumption
Time Frame: 24 hours postoperative
The pain score will be assessed every 4 h in 24 h and fentanyl will be given in a dose of 1 μg /kg when Visual analogue score (VAS) is 4 or more. Any out breaking pain will be treated with increments of fentanyl in a dose of 0.5μg/kg.
24 hours postoperative
Intraoperative and postoperative complications
Time Frame: Intraoperative and 24 hours postoperative
e.g. hypotension, bradycardia and vomiting
Intraoperative and 24 hours postoperative

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.
