Patient warming; a necessary technique for pre, peri and post-operative interventions

Hypothalamus is the temperature control center of the human body, despite temperature it also regulates various functions. During surgical intervention this center becomes vulnerable, and patient warming method becomes essential to make the surgical process more feasible.

The temperature controlling involves during Pre (before), Peri (around) and Post (after) operative time because, at a lower temperature (hypothermia), body’s metabolic demand lessens; making the surgical period live-saving as well. Also

  • It is responsible for infection control
  • Lessen body’s oxygen demand
  • Preserve organs
  • Make anesthesia intervention easier

And much more, same as hyperthermia (warmth) is induced to make patient’s temperature normal i.e. 37 centigrade. Hence all these conditions may vary according to the surgical procedure and duration.

What is normothermia?

Normothermia is known as controlling body temperature to normal. Before and after surgery patient should be kept to normothermia, for proper body functioning. There arises a concept of radiation, convection, and conduction.

These all are heat transferring methods use all around the world to understand the transformation of heat from one body to another.

The conduction is transferring of heat energy from an object with higher kinetic energy to the lower kinetic energy. This refers to the loss of heat from the skin to air.

Convection takes place through fluid or air, while radiation does not need any medium it is just simple heat transfer.

Why normothermia is important?

During hospital stay normothermia become necessary as it;

  • Reduce hospital stay
  • Lessen infectious diseases
  • Decrease chances of heart emergencies
  • Control the surgical bleed

Bair Hugging System

For this reason, to control and manage patient temperature, Bair hugging system is used in the form of disposable blankets. This system is used during, before and after surgery on the bed due to the sudden heat loss of the patient to the surrounding.

It is a basic method to control convection and radiation, used everywhere in the world for major and minor surgeries.

Fluid Warmers

Fluid warmers work through convection method, overcoming the hypothermia via crystalloid, colloids or blood products. This method is used during and before surgery to prevent heat loss from the patient body. This method is usually done during cardiac surgeries and other surgeries that require long anesthetized period.

Air Free Patient Warming

It is a new method of controlling patient temperature during surgery without air or any other medium. As it decreases the chance of infection because bed sole is an authentic issue of every surgical patient. Due to less contact of fluid or any other medium between patient and warmer, it makes sure to decrease pathogenesis.

Similarly, due to this latest method of heat conservation, energy loss can be prevented to higher levels.

Hence it is proved that maintaining the normal body temperature is necessary for the patient’s wellbeing.
