Comparing the Effect of Spinal Bupivacaine Versus Spinal Prilocaine on Maternal Blood Pressure in Cesarean Section

March 16, 2025 updated by: Mohamed Gaber Ahmed, South Valley University

Comparison Between the Effect of Spinal Bupivacaine Versus Spinal Prilocaine on Maternal Blood Pressure in Cesarean Section

one of the most common complications associated with spinal anesthesia is hypotension, which can have adverse effects on both the mother and the fetus. The present study compare prilocaine versus bupivacaine in spinal anesthesia on hypotension and there effect on maternal outcomes.

Study Overview

Status

Status

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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.

Ages Eligible for Study

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
Maternal arterial blood pressure
Time Frame: at base line before induction and every 3 minute during the first 15 min after spinal then every 5 mins until the end of surgery and every 1 hour postoperatively for 6 hours
Noninvasive blood pressure will be measured at selected time frame.. Hypotension will be defined as a decrease of systolic blood pressure of at least 20% from baseline. Upon its occurrence, and/or appearance of nausea and dizziness, treatment will be immediately with ephedrine 5mg/ dose
at base line before induction and every 3 minute during the first 15 min after spinal then every 5 mins until the end of surgery and every 1 hour postoperatively for 6 hours

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
Evaluation of duration of motor block
Time Frame: will be assessed before skin incision and every 15 min intervals until the end of surgery and then at 30-min intervals until its complete regression
the time to motor block regression (duration of motor block), defined as the time between complete block (score 1) after induction of prilocaine or bupivacaine and no motor block (score 6) on the Modified Bromage scale (1, complete motor block; 2, almost complete motor block, ability to move the feet only; 3, ability to move the knees; 4, ability to raise the leg but unable to keep it raised; 5, ability to keep the leg raised for 10 s; 6, no weakness).
will be assessed before skin incision and every 15 min intervals until the end of surgery and then at 30-min intervals until its complete regression
Total dose of ephedrine
Time Frame: From beginning of administration of spinal anesthesia until complete regression of motor blockade
When hypotension occurred postspinal ephedrine 5mg per dose will be given to restore blood pressure to 90% of its baseline value.
From beginning of administration of spinal anesthesia until complete regression of motor blockade
