Definition of Terms:

 Hot Sitz bath
– is a procedure whereby patient’s perineal area is submerged to water with solutions depending on the needs of the client.
- a bath in which only the pelvic area is immersed in warm fluid.

 Perilite Exposure
– application of dry heat to perineal area in order to provide comfort and increase blood circulation and hasten wound healing by means of perineal lamp.
- 20-50 centimeters or 18-24 inches away from the body to be exposed.

 Heat application
– is a process of applying heat through radiation and convection

 Dry heat
– requires a higher temperature and a longer period of heating

 Moist heat
- utilizes hot air that is heavily laden with water vapor

 Radiation
- is the transfer of heat through electromagnetic radiation. For any body the reflectivity depends on the wavelength distribution of incoming electromagnetic radiation and therefore the temperature of the source of the radiation.

 Convection
- is a combination of conduction and the transfer of thermal energy by fluid circulation or movement of the hot particles in bulk to cooler areas in a material medium.

 Conduction
- is the transfer of thermal energy from a region of higher temperature to a region of lower temperature through direct molecular communication within a medium or between mediums in direct physical contact without a flow of the material medium

 Episiotomy
– refers to an incision through the perineum that allows for less pressure on the fetal head during delivery and prevents lacerations of the perineum.

 Episiorraphy
-operation for repairing the episiotomy

 Perineorrhaphy
– Operation for repairing laceration of perineum usually following delivery


1. Relief of pain and muscular spasm
2. -provides comfort by relief pain
3. -it relaxes muscles and capillaries making pain tolerable
4. Increases blood circulation
5. Hastens wound healing following an episiotomy repair
6. -increases circulation of blood
7. -increases supply of oxygen and nutrient which promotes wound healing
8. Reduces edema and soreness
9. -it releases dry heat and thus help reduce edema and soreness
10. -alleviated by relax muscles and capillaries

1. Reduces soreness
2. Relieves swelling and pain
3. brought about vasodilatations, increases circulation, increases capillary permeability, venous congestion of injured tissues
4. Hastens healing
5. increases blood circulation and with all its nutrients
6. Promotes comfort and relaxation
7. Cleanses and reduces inflammation of perineal, and areas of client
8. the presence of moist softens exudates and other hardened substances
9. Stimulates voiding
10. it stimulates voiding and elimination by peristaltic activity

Process of Heat transfer

-the transfer of heat from a warm object to cooler object or vice versa by contact
-is the transfer of thermal energy from a region of higher temperature to a region of lower temperature through direct molecular communication within a medium or between mediums in direct physical contact without a flow of the material medium.

-heat transfer by means of movement of liquid or gas
-is a combination of conduction and the transfer of thermal energy by fluid circulation or movement of the hot particles in bulk to cooler areas in a material medium.
-this transfer occurs in sitz bath.

- is the transfer of heat through electromagnetic radiation. For any body the reflectivity depends on the wavelength distribution of incoming electromagnetic radiation and therefore the temperature of the source of the radiation.

Physiological responses to heat

• Vasodilation or increase in capillary surfaces
- Heat causes vasodilation and increases blood flow to the affected area bringing oxygen nutrients, antibodies and leukocytes.
• Increase in capillary permeability
- heat increases capillary permeability which allows extra cellular fluid and substances such as plasma proteins to pass through the capillary walls and may result in edema or an increase in pre-existing edema.
• Increase blood flow
• Increase cell metabolism
• Increase supply of nutrients
• Increase removal of wastes
• Relaxation of muscles
• Softening of exudates
• Increase peristalsis
• Increase body temperature

Variables that influences the effectiveness of heat

• Individual tolerance
– tolerance is influenced to some degree by age, condition of skin, the
condition of nervous and circulatory system. Young children, elderly clients, diabetic clients and individuals with circulatory or sensory alterations have low tolerance for heat.
- The very young and the very old generally have the lowest tolerance. Persons
- who have neurosensory impairments may have a high tolerance, but the risk of injury is greater.

• General conditions of patient
– shock or metabolic disorders such as diabetes increase the hazard of tissue
damage. Impaired perception because of individual’s level of
consciousness, medications and mental impairment may make it difficult
to determine patient’s response to end potential damage from application
of heat.

• Intactness of the skin
- Injured skin areas are more sensitive to temperature variations

• Whether the heat is moist or dry
– moist heat penetrates more deeply than dry heat because water is a good
conductor of heat. Application of moist heat should be at a lower
temperature than applications of dry heat.

• Size of skin area to be treated
– the greater the body area to be treated, the lower the temperature should be.

• Environmental temperature
– in warm or in humid environment, heat can’t be dissipated through
evaporation to some degrees that it can dry or cool circumstances.

• Length of Exposure
- People feel hot applications most while the temperature is changing. After a period of time, tolerance increases.

• Location of area to be covered
– individual tolerance to heat depends on the number of heat receptors in body
parts. In general, the inner aspects of thighs and arms, the axillae, the chest
and the abdomen are more sensitive to heat than the other parts of the body.

- The back of the hand and foot are not very temperature sensitive. In contrast the inner aspect of the wrist and forearm, the neck, and the perineal area are temperature sensitive.

Therapeutic uses of heat

- Heat is generally considered to produce a relaxation effect and increase the contractility of muscles.

- Heat relieves pain by promoting muscle relaxation, increasing circulation, and promoting psychological
relaxation and a feeling of comfort.

- This effect is achieved by allowing greater distention of muscles and connective tissue.

- Heat reduces joint stiffness by decreasing viscosity of synovial fluid and increasing tissue distensibility.


Dry Heat
Less risks of burns to skin than moist application
Retains temperature longer since not influenced by evaporation
Doesn’t cause maceration

increases body fluid loss through sweating
Doesn’t penetrate deep into tissues
Increase drying of skin

Moist Heat
Moist application reduces drying of skin and softens wound exudates
Warm moist doesn’t promote sweating and insensible fluid loss
Moist heat penetrates deeply into tissue layers
Moist compresses comfort well to area of body being treated

Moist heat creates a greater risk for burns to skin since moisture conducts heat
Prolonged exposure can cause maceration of skin
Moist heat will cool rapidly because of moist evaporation

-invisible heat rays readily seen in use of infrared; ultraviolet rays or electromagnetic waves

Hot Sitz Bath
• Post partum mother with episiotomy wound
• With rectal or vaginal surgery

• Patients with hemorrhage
• Mother who had undergone CS delivery
• Multiparity with wound
• Before 24 hours of postpartum

Perilite Exposure
• Patients who have undergone rectal or perineal surgery
• Post-partum patients with episiotomy wounds
• Patients having vaginal inflammation or bladder spasm
• Patients with painful or local irritation from hemorrhoids

• Patients with cardiovascular condition
• Presence of cyst or malignancy in the area
• Patients with open wounds with hemorrhage
• Patients with burns or fracture at the lower limbs
• Heat lamps are contraindicated in pressure ulcer care

Principles involved in Hot Sitz Bath

- client who has episiotomy has painful hemorrhoids or vaginal inflammation may benefit from immersing pelvic area in warm water.
- -sitz bath requires special attention to body posture ad limb position to avoid cramping and constriction of circulation from pressure against edge of tub.

- application of heat to open wounds that may rupture may demand a sterile technique instruments should be sterile.

- application is for thermal effect and there’s no wound, materials should be kept cleaned to reduce transfer of bacteria.

• nurse should explain first the procedure to patient to gain cooperation
• nurse should know if patient is sensitive to warmness.

• heat generally is the speed of chemical reaction since metabolism is largely caused by chemical reactions, the application of heat speeds metabolism either locally or generally
• the solvent action of water maybe increased by adding other substances like soap.
• Magnesium Sulfate is used for preterm labor or commonly used for treatment of preeclampsia to slow uterine contractions.


• heat is most valuable and most versatile physical for treatment.
• water has also great capacity, it undergoes change more slowly than other substances. It also gives off more heat.
• heat maybe transferred from 1 place to another by conduction, convection and radiation.
• application of heat & cold employs physical agents; heat, light & electricity.

Principles involved in Perilite Exposure

• through blood vessels and nerves, skin and connections they make with nerves and blood vessels of body, practically all parts of body maybe influenced by application of heat to skin.

• the application of heat to open wounds of lesions may rapture demands a sterile technique.

• position of mother is dorsal recumbent with legs and knees flexed to allow proper exposure of area to be treated

• application of heat employs physical agents: heat, water and light. Heat maybe transferred from one place to another by radiation (perilite exposure) and convection (hot sitz) bath.

• nurse explains purpose of treatment in order to gain cooperation.

• the patient needs to cooperate with nurse in order for treatment to be effective and to add patients early recovery.
