Which interventions reduce hypothermia risk in preterm infants?
Extremely preterm infants (< 28 weeks' gestation) appeared to benefit the most. Other interventions such as thermal mattresses, skin‐to‐skin care, and plastic caps also reduce hypothermia risk when compared with routine care, but these findings are based on two or fewer studies with small sample sizes.
What should I look for in a patient with hypothermia?
Look for the following symptoms of hypothermia: Take action to help the person get warm. Don't heat the person's body too fast; instead, do it gradually, so that the shock of the heat doesn't cause further damage. Helping the person's body temperature warm to a safe level is the most important step in treating hypothermia.
What is the best method of preventing hypothermia?
How to prevent hypothermia. Wear warm, multi-layered clothing with good hand and feet protection (avoid overly constricting wrist bands, socks, and shoes). Wear warm headgear. This is particularly important since significant heat is lost through an unprotected head.

Is hypothermia alcohol related?
There are some claims that up 70% of hypothermia are alcohol related. Hypothermia Prevention is a very important thing to consider, this and every Winter. Preparing correctly and being aware of the dangers is the best way to protect yourself and to protect others.
Is it bad to drink alcohol in cold weather?
Alcohol is very dangerous in the cold weather, for a few reasons. For one, drinking alcohol increases the risk of hypothermia because it's a vasodilator, it widens the blood vessels. This makes a person feel warm, without being warm. It also increases heat loss.
How to prevent hypothermia?
Prevention of Hypothermia. Hypothermia can be prevented by dressing properly, by avoiding potentially dangerous weather conditions, and by drying out as quickly as possible when you get wet. High-calorie foods, such as chocolate, peanuts, or raisins, provide quick energy that helps your body produce heat. Unit 8 of 10.
What causes body temperature to fall?
Hypothermia occurs when your body loses heat faster than it can produce it, causing your core body temperature to fall. Hypothermia is often induced by cold, wet conditions, such as rain, snow, sleet, or immersion in water. However, hypothermia can occur at temperatures as high as 50° Fahrenheit.
Can you get hypothermia from rain?
However, hypothermia can occur at temperatures as high as 50° Fahrenheit. Moisture from perspiration, humidity, and dew or rain on bushes and trees also can soak your clothing over time, putting you at risk in cold weather. Wet or damp clothes will draw heat out of your body more rapidly than cold air.
How to prevent hypothermia?
One of the best ways to prevent hypothermia is to dress in appropriate outdoor clothing, use heat packs or other body warmers as necessary, keep as little skin exposed as possible, stay dry, and move to a warm environment when there are signs of body cooling (e.g., numbness, instability, confusion).
Why does hypothermia occur in all 50 states?
One reason for this is that the human heart will stop at a body temperature of about 64 F. This corresponds to a room with cold air conditioning.
How long has hypothermia been recognized?
The symptoms of hypothermia have been recognized for 2,000 years. 7 The human body works best within a very narrow range of body temperature and decline in body temperature leads to a spiral of declining physical and mental ability that can exacerbate cooling, leading to incapacitation and death (see Table 1 ).

A Common Danger. Accidental hypothermia affects and kills people every year. In 2019, more than 1,000 died of hypothermia in the United States with almost half of those deaths occurring in the Great Lakes states of Illinois, Indiana, Michigan, Minnesota, Ohio, Pennsylvania, and Wisconsin. 1 In the Great Lakes states, ...
Why do people use ropes in water?
A rope with a large loop knotted at the end could allow a person in the water to slip it around their body so that bystanders could pull them free of the water. Extending a tree branch to a person in the water might provide some flotation and a means of pulling them free if they can grip it.
What happens during cold shock?
During the incapacitation phase there is a rapid cooling of skin, nerves, and muscles that results in a rapid loss of dexterity, sense of touch, muscle strength and speed.
Why does immersion cause death?
The reason accidental immersion causes lost body function and death is because the body's core temperature drops ( Table 2 ). The human body works well only when it can maintain a fairly narrow range of internal temperature.
How to help someone with hypothermia?
Be gentle. When you're helping a person with hypothermia, handle him or her gently. Limit movements to only those that are necessary. Don't massage or rub the person. Excessive, vigorous or jarring movements may trigger cardiac arrest.
How to warm blood?
Heart bypass machines also may need to be used. Warm intravenous fluids. A warmed intravenous solution of salt water may be put into a vein to help warm the blood.
How to raise body temperature?
Depending on the severity of hypothermia, emergency medical care for hypothermia may include one of the following interventions to raise the body temperature: 1 Passive rewarming. For someone with mild hypothermia, it is enough to cover them with heated blankets and offer warm fluids to drink. 2 Blood rewarming. Blood may be drawn, warmed and recirculated in the body. A common method of warming blood is the use of a hemodialysis machine, which is normally used to filter blood in people with poor kidney function. Heart bypass machines also may need to be used. 3 Warm intravenous fluids. A warmed intravenous solution of salt water may be put into a vein to help warm the blood. 4 Airway rewarming. The use of humidified oxygen administered with a mask or nasal tube can warm the airways and help raise the temperature of the body. 5 Irrigation. A warm saltwater solution may be used to warm certain areas of the body, such as the area around the lungs (pleura) or the abdominal cavity (peritoneal cavity). The warm liquid is introduced into the affected area with catheters.
What is passive rewarming?

A warm saltwater solution may be used to warm certain areas of the body, such as the area around the lungs (pleura) or the abdominal cavity (peritoneal cavity). The warm liquid is introduced into the affected area with catheters.
How to protect yourself from cold weather?
Cut away clothing if necessary to avoid excessive movement. Cover the person with blankets. Use layers of dry blankets or coats to warm the person. Cover the person's head, leaving only the face exposed. Insulate the person's body from the cold ground.
What causes the body temperature to drop?
Heat applied to the arms and legs forces cold blood back toward the heart, lungs and brain, causing the core body temperature to drop. This can be fatal. Don't apply direct heat. Don't use hot water, a heating pad or a heating lamp to warm the person.
Abstract
Newborn admission temperature is a strong predictor of outcomes across all gestations. Hypothermia immediately after birth remains a worldwide issue and, if prolonged, is associated with harm. Keeping preterm infants warm is difficult even when recommended routine thermal care guidelines are followed in the delivery room.
Summary of findings
Plastic wrap or bag compared with routine care in preterm and/or low birth weight infants
Background
Keeping preterm infants sufficiently warm immediately after birth, especially during resuscitation, is difficult even when routine thermal care guidelines are followed. Hypothermia is defined by the World Health Organization (WHO) as a core body temperature < 36.5°C, or a skin temperature < 36°C ( WHO 1997 ).
Objectives
To assess the efficacy and safety of interventions designed for prevention of hypothermia in preterm and/or low birth weight infants applied within 10 minutes after birth in the delivery room, compared with routine thermal care or any other single/combination of intervention (s) also designed for prevention of hypothermia in preterm and/or low birth weight infants applied within 10 minutes after birth in the delivery room..
Results
See the Characteristics of included studies table, the 'Risk of bias' table ( Figure 2 ), and Characteristics of excluded studies, Characteristics of studies awaiting classification, and Characteristics of ongoing studies tables.
Discussion
Hypothermia (body temperature below normal) on admission to neonatal units continues to be a persistent problem worldwide across all climates. "A naked newborn exposed to an environmental temperature of 23°C suffers the same heat loss as a naked adult at 0°C" ( WHO 1997 ), and this is negatively correlated with gestation and birth weight.
Authors' conclusions
Hypothermia remains a worldwide problem, especially for small infants and those born preterm. Across all gestations, admission temperature is a strong predictor of mortality and morbidity ( Perlman 2015 ).
