The Effect of Caffeine Therapy in Cardiovascular Stability in Preterm Neonates: a Prospective Study at the Neonatal Intensive Care Unit of Assiut University Children Hospital

Preterm neonates younger than 37 weeks gestational age receiving caffeine therapy for apnea of prematurity in a NICU setting.

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.

Detailed Description

The study population consists of 40 preterm neonates admitted to the Neonatal Intensive Care Unit at Assiut University Children Hospital. Inclusion criteria restrict participants to those with a gestational age below 37 weeks who are prescribed caffeine citrate therapy to manage apnea of prematurity. Neonates with major congenital anomalies or those requiring vasopressors at baseline are excluded. The cohort is monitored closely for cardiovascular parameters and adverse reactions related to caffeine administration. Demographic and clinical baseline data include prenatal risk factors, gestational and postnatal age, and birth weight. This focused population allows investigation of caffeine's impact on vulnerable cardiovascular physiology during early neonatal life.

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.

Sampling Method

Non-Probability Sample

Study Population

Preterm neonates receiving standard caffeine citrate therapy for apnea of prematurity, including a loading dose of 20-25 mg/kg followed by maintenance dosing (5-10 mg/kg daily). Cardiovascular parameters and side effects are monitored longitudinally.

Description

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
Change in mean arterial blood pressure after caffeine therapy in preterm neonates.
Time Frame: Baseline before caffeine administration and at 1, 6, 12, and 24 hours after caffeine dose.
Mean change in mean arterial blood pressure (mmHg) in preterm neonates receiving caffeine therapy for apnea of prematurity, comparing post-caffeine values with baseline pre-caffeine values.
Baseline before caffeine administration and at 1, 6, 12, and 24 hours after caffeine dose.
Change in perfusion index after caffeine therapy in preterm neonates.
Time Frame: Baseline before caffeine administration and at 1, 6, 12, and 24 hours after caffeine dose.
Mean change in perfusion index (unitless value from pulse oximeter) in preterm neonates receiving caffeine therapy for apnea of prematurity, comparing post-caffeine values with baseline pre-caffeine values.
Baseline before caffeine administration and at 1, 6, 12, and 24 hours after caffeine dose.
Change in heart rate after caffeine therapy in preterm neonates.
Time Frame: Baseline before caffeine administration and at 1, 6, 12, and 24 hours after caffeine dose.
Mean change in heart rate (beats per minute) in preterm neonates receiving caffeine therapy for apnea of prematurity, comparing post-caffeine values with baseline pre-caffeine values, and documenting episodes of tachycardia defined as heart rate greater than 180 beats per minute.
Baseline before caffeine administration and at 1, 6, 12, and 24 hours after caffeine dose.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Estimated)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
June 30, 2026

Primary Completion (Estimated)

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.

Study Completion (Estimated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
