UNIT 5 - TREATMENT OF DEHYDRATED PATIENTS
Dehydration occurs when the water and electrolytes lost during diarrhoea are
not fully replaced. As dehydration develops, various signs and symptoms appear
which can be used to estimate the extent of dehydration and guide therapy. Three
categories of dehydration can be recognized, each of which is associated with a
specific Treatment Plan (see Unit 3). In increasing order of severity, these
Treatment Plan A (for treatment of
diarrhoea at home) is described in Unit 4. The present unit describes the
treatment at a health facility of infants and children with some
dehydration or severe dehydration, using Treatment Plans B and C,
PATIENTS WITH SOME DEHYDRATION - TREATMENT PLAN B
Children with signs indicating there is some dehydration usually do
not need to be admitted to hospital. They can be treated in a special area of
the clinic known as the "ORT corner" or the "oral rehydration area". Mothers
should stay with their children to help with the treatment and learn how to
continue it at home, after the child is rehydrated.
Tasks involved in Treatment Plan B
The main tasks of Treatment Plan B are to:
OBSERVE THE CHILD CAREFULLY AND
HELP THE MOTHER GIVE ORS SOLUTION.
Show her how much solution to give her child.
- continue breast-feeding;
- estimate the amount of ORS solution to be given during the first 4 hours,
- show the mother how to give ORS solution;
- monitor treatment and reassess the child periodically until rehydration is
- resume giving foods other than breast milk after 4 hours;
- identify patients who cannot be treated satisfactorily with ORS solution by
mouth and adopt a more appropriate method of treatment;
- give instructions for continuing the treatment at home after rehydration is
completed, following Treatment Plan A.
- If the child wants more ORS than shown, give more.
- Encourage the mother to continue breastfeeding.
- For infants under 6 months who are not breastfed, also give 100-200 ml
clean water during this period.
Show her how to give it - a teaspoonful every 1-2 minutes for a child under
2 years, frequent sips from a cup for an older child.
Check from time to time to see if there are problems.
If the child vomits, wait 10 minutes and then continue giving ORS, but more
slowly; for example, a spoonful every 2-3 minutes.
If the child's eyelids become puffy, stop ORS and give plain water or
breast milk. Give ORS according to Plan A when the puffiness is
AFTER 4 HOURS, REASSESS THE CHILD USING THE ASSESSMENT CHART. THEN SELECT
PLAN A, B OR C TO CONTINUE TREATMENT:
If there are no signs of dehydration, shift to Plan A.
When dehydration has been corrected, the child usually passes urine and may
also be tired and fall asleep.
If signs indicating some dehydration are still present, repeat Plan
B, but start to offer food, milk and juice as described in Plan A.
If signs indicating severe dehydration have appeared, shift to Plan
IF THE MOTHER MUST LEAVE BEFORE
COMPLETING TREATMENT PLAN B:
Show her how much ORS to give to finish the 4-hour treatment at home.
Give her enough ORS packets to complete rehydration, and for 2 more days as
shown in Plan A.
Show her how to prepare ORS solution.
Explain to her the three rules in Plan A for treating her child at
to give ORS or other fluids until
to feed her child
to bring the child back to the health worker, if necessary.
How much ORS solution should be
When there is some dehydration the deficit of water is between 50 and 100 ml
for each kg of body weight. If the child's weight is known, the amount of ORS
solution required for rehydration can be estimated, using 75ml/kg as the
approximate deficit. If the child's weight is not known, the estimated deficit
can be determined using the child's age, although this approach is less precise.
Both methods are shown in the chart in Figure 5.1, which indicates the range of
fluid volumes that is appropriate for a child of a given weight or age.
Alternatively, the approximate ORS volume (in ml) can be calculated by
multiplying the weight (in grams) times 0.075. Thus, a child weighing 8000 grams
would require about (8000 x 0.075) 600 ml of ORS solution.
It should be emphasized that the range of fluid volumes shown in the chart is
an estimate of what is needed and should be used only as a guide. The
actual amount given should be determined by how thirsty the patient is and by
monitoring the signs of dehydration, bearing in mind that larger volumes will be
required by larger patients, those with more advanced signs of dehydration, and
those who continue to pass watery stools during rehydration. The general rule is
that patients should be given as much ORS solution as they will drink, and the
signs of dehydration should be monitored to confirm that they are improving.
How to give ORS solution
The estimated amount of ORS solution to be given during the first 4 hours
should be explained to the mother, using measuring units with which she is
familiar, e.g., 4 cups, 2 glasses, etc.
Give one teaspoonful every 1-2 minutes to children under 2 years of age,
or offer frequent sips from a cup to older children. Adults may drink the
solution freely. Try to give the estimated amount in a period of 4 hours.
The mother should then learn how to give ORS solution to her child. This is
best done by means of a brief demonstration by a nurse or health worker,
following which the mother should give her child the solution, under
supervision, observing the following guidelines:
If the child vomits, wait 10 minutes, then continue giving ORS solution,
but more slowly: a spoonful every 2-3 minutes.
If the child will drink more than the estimated amount of ORS solution and
is not vomiting, give more; if the child refuses to drink the estimated amount,
and the signs of dehydration have disappeared, stop giving ORS solution
and shift to Treatment Plan A.
If the child is breast-fed, continue breast-feeding during therapy with ORS
For infants under 6 months of age who are not breast-fed, also give 100-200
ml of clean water during the first 4 hours.
When the mother can administer the
fluid comfortably and the child is taking it well, she should be shown how to
mix ORS solution using containers of a type available in her home or that she
can obtain easily. The health worker should demonstrate the method by mixing a
packet. Then the mother should prepare the solution herself to ensure that she
During rehydration with ORS solution the child's treatment and progress
should be monitored as follows:
Check periodically to be certain that the mother is giving ORS solution
correctly and the child is taking it satisfactorily.
Record the amount of solution taken and the number of diarrhoea stools
Watch for problems, such as signs of worsening dehydration (e.g., further
loss of skin elasticity, increasing lethargy) or increasing stool output, which
may indicate that ORT will not be successful. The management of such patients is
discussed later in this unit.
Watch for puffy eyelids, which are a sign of overhydration; if these are
seen, ORS solution should be stopped, although breast-feeding and the provision
of plain water should continue. When the puffiness is gone, the child can be
considered to be rehydrated and further treatment should follow Plan A.
Reassessing the patient
After 4 hours, carefully reassess the child's hydration status following the
assessment chart in Unit 3, Figure 3.1:
If the child has no signs of dehydration, rehydration is complete.
The child may be sent home after carefully showing the mother how to continue
treatment at home with ORS and feeding following Treatment Plan A, giving her
enough ORS packets for two days, and explaining the signs that mean the child
should return to the health centre (see Unit 4).
If signs indicating some dehydration are still present, continue
rehydration therapy by again giving the volume of ORS solution estimated
from Treatment Plan B. Continue this approach until the signs of dehydration
have disappeared. Also start to offer food and drink as described in Treatment
If the child is having frequent watery stools and the signs of
dehydration have worsened, ORT should be temporarily stopped and the child
rehydrated intravenously as described in Treatment Plan C (see Figure 5.2).
Patients who cannot remain at the
If the mother must leave before completing rehydration therapy:
Show her how much ORS solution to give to complete the initial 4-hour
treatment at home. If possible, she should make up some solution under
supervision and give it during the journey.
Give her enough ORS packets to complete the initial rehydration and
for 2 additional days; show her how to make the fluid.
Explain to her how to continue the treatment of her child at home following
Treatment Plan A.
PATIENTS WITH SEVERE DEHYDRATION - TREATMENT PLAN C
Children with signs of severe dehydration can die quickly from
hypovolaemic shock. They should be treated immediately, following
Treatment Plan C (Figure 5.2).
Tasks involved in Treatment Plan C
The main tasks of Treatment Plan C are to:
decide how fluid will be given: (a) by IV drip, (b) by nasogastric
infusion, or (c) orally;
decide how much IV fluid to give; then give the fluid and reassess the
shift to Treatment Plan B or A when the child is no longer severely
treat suspected cases of cholera with an appropriate antibiotic.
Deciding how fluid will be
The treatment of choice for severe dehydration is IV rehydration, because it
is the most rapid way to restore the depleted blood volume. Intravenous
rehydration is especially important if there are signs of hypovolaemic shock
(i.e., the patient has a very rapid and weak, or absent radial pulse, cool and
moist extremities; the patient is very lethargic or unconscious). Alternative
routes for fluid replacement should only be considered when IV rehydration is
not possible or cannot be obtained nearby, within 30 minutes.
If IV therapy is not possible, a nasogastric (NG) tube can be used to give
ORS solution, provided there is a person trained in its use. However, this
approach is not as satisfactory as IV infusion because the fluid cannot be given as rapidly and additional time is required for it to be absorbed from
the intestine. The maximum rate of fluid infusion is about 20 ml/kg/hour; with
higher rates, abdominal distension and repeated vomiting are frequent problems.
If IV and NG therapy are not possible, or will be delayed, and the child
is able to drink, ORS solution should be given by mouth at a rate of 20
ml/kg/hour. This approach has the same disadvantages as NG therapy; moreover, it
cannot be used for patients who are very lethargic or unconscious. Children
under 2 years should be given ORS solution by spoon, about one teaspoonful per
minute; older children and adults may drink the solution from a cup. Patients
with abdominal distension caused by paralytic ileus should not be given ORS
solution either orally or by NG tube.
If fluid replacement is not possible by any of these routes, refer the
child urgently to the nearest centre where IV or NG therapy can be given.
Selecting an appropriate IV fluid
A variety of different solutions is available for IV infusion (see Unit 2).
However, some do not contain appropriate amounts of the electrolytes required to
correct the deficits found in dehydration due to diarrhoea. Ringer's Lactate
Solution (also called Hartmann's Solution for Injection) is the preferred
commercially available solution. If it is not available, normal saline (0.9%
NaCl), half-strength Darrow's solution with 2.5% or 5% dextrose or half-normal
saline in 5% dextrose may be used. IV solutions containing only dextrose
(glucose) should not be used.
Putting up an intravenous drip
IV therapy should be given only by trained persons. Some points to remember
are given below (see also Annex 5):
Needles, tubing, bottles, and fluid must be sterile.
IV therapy can be given in any convenient vein. Those most suitable are in
front of the elbow (antecubital vein) or, in infants, on the scalp. In cases of
hypovolaemic shock, particularly in adults, simultaneous infusion into two veins
may help to restore blood volume rapidly.
When a peripheral vein cannot be found because of severe hypovolaemia, a
needle may be introduced into the femoral vein where it must be held firmly in
place. (The femoral vein is located just medial to the femoral artery, which can
be easily identified by its pulsation.) A large amount of fluid can then be
infused very rapidly. The IV site should be changed to a peripheral vein as soon
as one becomes evident. A venous incision ("cut-down") should not be necessary;
this takes longer to perform and is liable to become infected.
If IV therapy will be delayed and the patient is able to drink,
start giving ORS solution by mouth until the drip is running.
Deciding how much IV fluid to
If possible, patients with severe dehydration should be weighed so that their
fluid requirements can be determined accurately. The fluid deficit in severe
dehydration equals about 10% of body weight (i.e., 100 ml/kg).
Infants should be given IV fluid at a rate of 30 ml/kg in the first
hour, followed by 70 ml/kg in the next 5 hours, thus providing a total of 100
ml/kg in 6 hours. Older children and adults should be given IV fluid at a
rate of 30 ml/kg within 30 minutes, followed by 70 ml/kg in the next 2.5 hours,
thus providing a total of 100 ml/kg in 3 hours. For all patients it is
useful to mark the IV fluid bottles, indicating the level the fluid should reach
after each hour of infusion.
After the first 30 ml/kg have been given, a strong radial pulse should be
easily felt. If it is still very weak and rapid, a second infusion of 30 ml/kg
should be given at the same rate; however this is rarely necessary. Small
amounts of ORS solution should also be given by mouth (about 5 ml/kg/hour) as
soon as the patient is able to drink, in order to provide additional potassium
and base; this is usually possible after 3-4 hours (infants) or 1-2 hours (older
Reassessing the patient
During rehydration, the patient's progress should be assessed at least hourly
until there is a definite improvement. Particular attention should be paid to:
the signs of dehydration (see Unit 3, Figure 3.1);
the number and nature of the stools passed;
any difficulty in giving fluids.
Signs of a satisfactory response to
rehydration are: return of a strong radial pulse, improved level of
consciousness, increased ability to drink, much improved skin turgor, and
passage of urine. When these are seen, the interval between reassessments can be
If the signs of dehydration remain unchanged or become worse, and especially
if the patient has also passed several watery stools, the rate of fluid
administration and the total amount of fluid given for rehydration should be
Alternative methods of rehydration
An NG tube (size 6-8 French for a child, 12-18 for an adult) should be placed
by a person trained in its use (see Annex 6). While the tube is in place, the
head should be kept slightly raised to reduce the risk of regurgitated fluid
entering the lungs.
Patients with severe dehydration should receive about 120 ml of ORS solution
per kg of body weight over 6 hours, administered at a steady rate of 20 ml per
kg per hour. This rate should be reduced only if there is repeated vomiting or
increasing abdominal distension.
Patients should be reassessed every 1-2 hours until a satisfactory response
to treatment is seen. If the signs of dehydration fail to improve or become
worse after 3 hours of attempted NG rehydration, this approach is not likely to
be successful and the patient should be sent urgently to a facility where IV
treatment is possible.
The amount of fluid to be given orally and the monitoring of patients during
oral rehydration are the same as described above for NG rehydration. It is
helpful to measure out the amount of fluid required each hour into a glass or
other container, even though it may be given by spoon. If a patient cannot drink
the required amount of fluid or vomits frequently, the rate of administration
should be slowed and the rehydration period lengthened. If signs of dehydration
fail to improve or become worse after 3 hours of attempted oral rehydration, the
patient should be sent urgently to a facility where IV treatment is possible.
Giving breast milk and water
In addition to rehydration therapy, the patient's normal need for water must
be met. Breast-feeding should be resumed as soon as an infant can suck. Infants
less than 6 months of age who are not breast-fed should be given 100-200 ml of
plain water during the first 6 hours, once they are able to drink; older
children and adults should be given water to drink as soon as they desire it,
provided that vomiting has subsided. (This is in addition to any ORS solution
Transition to Treatment Plans B and A
At the end of the planned rehydration period (usually 3-6 hours), the
patient's hydration status should be carefully reassessed. If signs of severe
dehydration are still present, rehydration therapy must be continued following
Treatment Plan C. Otherwise, further treatment should follow Plan B or Plan A,
depending, respectively, on whether some signs of dehydration remain or there
are no signs of dehydration. In either case, ORS solution should be used. Before
removing the IV line, however, it is wise to give ORS solution for at least one
hour to be certain ORT is feasible. If possible, patients presenting with severe
dehydration should be hospitalized until the diarrhoea subsides. Otherwise, they
should be observed for at least 6 hours after rehydration before returning home,
to make sure that the mother can maintain their hydration using ORS solution.
Treatment of suspected cholera
Children over 2 years of age and adults with severe dehydration caused by
acute watery diarrhoea who live in an area where cholera occurs, should be given
an appropriate oral antibiotic after vomiting subsides. This would usually be
tetracycline or doxycycline (see Annex 7). If V. cholerae 01 in the area
are known to be resistant to tetracycline, furazolidone, cotrimoxazole or
chloramphenicol may be used. Treatment of cholera with an appropriate antibiotic
helps to shorten the duration of diarrhoea, but does not diminish the need for
careful fluid replacement.
PATIENTS WITH PROBLEMS
A number of problems may arise during rehydration therapy, some of which
require specific treatment. In general, these fall into the three categories
Electrolyte and acid-base abnormalities
These include hypernatraemia, hyponatraemia, hyperkalaemia, hypokalaemia, and
base-deficit acidosis. The pathogenesis and clinical features of these disorders
are described in Unit 2. Usually they arise as dehydration is developing or when
the fluids used for rehydration do not have an appropriate composition. Although
certain clinical features may suggest a particular diagnosis, for example,
seizures suggest hypernatraemia or hyponatraemia, and paralytic ileus suggests
hypokalaemia, these signs are not specific and a diagnosis can be made with
certainty only by measuring serum electrolytes, bicarbonate, or pH. It is more
important to understand, however, that these disorders are all corrected
when ORS solution is used to treat dehydration as described in this unit and
kidney function is satisfactory.
Failure of oral rehydration therapy
A small number of patients with some dehydration cannot be treated
adequately with ORS solution by mouth and require IV (or NG) therapy. They
should receive Ringer's Lactate Solution (70 ml/kg intravenously over 3-4 hours)
and then be reassessed to determine whether ORT is possible or IV treatment
should be continued. Patients that fall in this category may have:
High rates of purging (frequent passage of voluminous liquid
Patients with watery diarrhoea who purge at very high rates (e.g., exceeding
15-20 ml/kg/hour) may be unable to drink sufficient ORS solution to replace
their continuing stool losses, so that their signs of dehydration worsen. Such
patients should be treated for several hours with IV fluid, until the rate of
Vomiting does not usually prevent successful
ORT because most of the fluid taken is actually retained and absorbed, despite
the obvious losses. When vomiting is frequent, the first step is to stop giving
ORS solution for 10 minutes, and then to resume giving it, but more slowly; most
patients can be managed successfully in this way. Occasionally, however, severe
and repeated vomiting prevents effective oral rehydration. If the clinical signs
of dehydration do not improve, or become worse, fluids should be given
intravenously until the vomiting subsides. Remember that vomiting is often most
severe during dehydration and usually disappears as water and electrolytes are
replaced. Drugs should never be given to control vomiting because they
are not very effective and often cause the child to become sleepy, making ORT
Inability to drink:
Patients who cannot drink because of stomatitis
(due, for example, to measles, thrush, or herpes), fatigue, or central nervous
system depression induced by drugs (such as antiemetics or antimotility drugs)
should be given IV fluid or ORS solution by NG tube. If the patient is comatose,
fluid should be given intravenously, if possible, or by NG tube.
Abdominal distension and ileus:
If the abdomen starts to become
distended, ORS solution should be given more slowly. If abdominal distension continues to increase or is already well developed, and especially
if there is paralytic ileus with absent bowel sounds, ORT or nasogastric therapy
should be stopped and fluid given intravenously. Paralytic ileus may be caused
by opiate drugs (e.g., codeine, paregoric), hypokalaemia, or, more frequently,
by both acting together.
Clinically significant glucose malabsorption
is unusual during acute diarrhoea. However, when it does occur, the use of ORS
solution may cause a marked increase in watery diarrhoea with large amounts of
unabsorbed glucose in the stool and worsening signs of dehydration (see Unit 2,
Figure 2.4). The child may also become hypernatraemic and very thirsty. Special
tapes or test sticks can be used to detect glucose in the stool. Tests for
reducing substances, such as Benedict's solution or Clinitest (R) tablets, can
also be used (see Unit 7). When glucose malabsorption prevents successful ORT,
fluids should be given intravenously until diarrhoea subsides. Water may also be
given to drink until thirst is satisfied.
Dehydrated children occasionally develop convulsions either before or during
rehydration therapy. Some possible causes of seizures and their appropriate
treatment are as follows:
This occurs mostly in undernourished infants and
young children. A therapeutic test for hypoglycaemia in a comatose child
involves giving sterile 20% glucose solution intravenously; if hypoglycaemia is
the cause, giving 2.5 ml/kg of the solution over 5 minutes should cause a rapid
improvement in consciousness. After waking up, the child should be fed, given
ORS solution, or both, to prevent a recurrence.
Some young children (especially infants) develop
seizures when they have a fever; the risk is greatest when the fever is high,
e.g. exceeds 40° C. Treatment involves giving paracetamol or cooling by sponging
with tepid water and fanning.
Hypernatraemia or hyponatraemia:
See Unit 2 for a discussion of
these conditions. The preferred treatment is with ORS solution, unless there is
also glucose malabsorption (see above). When sufficient amounts are given to
correct dehydration and restore normal kidney function, serum sodium levels will
