Evaluation of Use of Plastic Bags to Prevent Neonatal Hypothermia-Part III
A study testing Incubator-torso bag and Incubator-no plastic bag in people with Hypothermia, run by University of Alabama at Birmingham at 1 site in Zambia.
Trial summary
The overall hypothesis is that plastic bags used in combination with WHO thermoregulation care will reduce the incidence of hypothermia in preterm/low birth weight and full term infants when compared to routine WHO thermoregulation care alone. Read more about this study

About this study
Official title: Randomized Evaluation of the Use of Plastic Bags to Prevent Neonatal Hypothermia in Developing Countries-Part III
The overall hypothesis is that plastic bags used in combination with WHO thermoregulation care will reduce the incidence of hypothermia in preterm/low birth weight and full term infants when compared to routine WHO thermoregulation care alone. Part III is for preterm/low birth weight infants with or without a plastic torso wrap during the first hour after birth to assist with temperature regulation during placement in an incubator.
Read the detailed description
Incubators in the developing world often lack humidifiers. The resting dry heat increases evaporative heat loss, the most prominent form of heat loss in premature infants due to their increased body surface area and immature stratum corneum. By potentially increasing humidity around the infants and decreasing evaporative heat losses, plastic bags may improve incubator warming. This study will compare the incidence of hypothermia in infants placed in an incubator for at least one hour randomized to receive standard incubator protocol (control group) or standard incubator protocol plus a plastic bag covering their torsos and lower extremities (intervention group). The axillary temperature of each infant will be taken before placement into the incubator and one hour later when the bag will be removed. Blood pressure, blood sugar, seizures, weight gain, hyperthermia, death, observation for respiratory distress syndrome, bronchopulmonary dysplasia, pneumothorax, sepsis, intraventricular hemorrhage, periventricular leukomalacia, necrotizing enterocolitis, intestinal perforation, pulmonary hemorrhage, incubator temperature, and humidity, and length of time in an incubator will be recorded throughout the hospitalization for all infants. With an estimated baseline hypothermia rate of 90% and a hypothesized 20% absolute risk reduction (22% relative risk reduction), a sample size of 118 will be used to have a power of 80% and a confidence interval of 95%.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Incubator-torso bagProcedure or surgery
While being placed into an incubator, infant will be placed into a plastic bag to his/her axillae and the bag will be folded and taped to itself to prevent it from covering the infant's nose or mouth. The infant will be wrapped in a blanket over the plastic bag and will receive a cloth hat. He/she will remain in the bag for one hour.
Incubator-no plastic bagProcedure or surgery
Infant will be placed in the incubator, wrapped in a blanket, with a cloth hat, according to standard protocol.
| Study group | Role | What they receive |
|---|---|---|
| Incubator-no plastic bag | Sham comparator | Placement into an incubator without a plastic bag Receives: Procedure: Incubator-no plastic bag |
| Incubator-torso bag | Active comparator | Placement into a plastic bag inside incubator Receives: Procedure: Incubator-torso bag |

Questions about this trial
What is this clinical trial studying?
A study testing Incubator-torso bag and Incubator-no plastic bag in people with Hypothermia, run by University of Alabama at Birmingham at 1 site in Zambia.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: withdrawn, as of the sponsor's last update on 20 Feb 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Zambia. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study was withdrawn before enrolling participants, so there are no results.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Axillary temperature 36.5-37.5 degrees Celsius (time frame: 1-72 hours). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Feb 2019.
