Health Problems of School-Age Children


Problems Related to Elimination


Enuresis


Enuresis (bedwetting), or nocturnal enuresis, is a common and troublesome disorder that is defined as intentional or involuntary passage of urine into bed (usually at night) in children who are beyond the age when voluntary bladder control should normally have been acquired. The inappropriate voiding of urine must occur at least twice a week for at least 3 months, and the chronologic or developmental age of the child must be at least 5 years. The predominant symptom is urgency that is immediate and accompanied by acute discomfort, restlessness, and urinary frequency. In addition, the urinary incontinence must not be related to the direct physiologic effects of a substance (e.g., diuretics) or a general medical condition (e.g., diabetes mellitus or diabetes insipidus, spina bifida, seizure disorder, or sickle cell disease).


Enuresis is more common in boys; nocturnal bedwetting usually ceases between 6 and 8 years of age. Enuresis can also be defined as primary (bedwetting in children who have never been dry for extended periods) or secondary (the onset of wetting after a period of established urinary continence). The passage of urine may occur only during nighttime sleep with the child remaining dry during the day (monosymptomatic), or it may be polysymptomatic, wherein the child has daytime urinary urgency and an occasional daytime accident in conjunction with other conditions such as sleep apnea, urinary tract infection, neurologic impairment, constipation, or emotional stressors (Berry, 2006; Katz and DeMaso, 2011). The nocturnal, monosymptomatic type is most common. The condition may be particularly distressing to adolescents, who may refuse therapy. Although enuresis may occur during the daytime, the following discussion primarily focuses on nocturnal enuresis.


Before psychogenic factors are considered, organic causes that may be related to enuresis should be ruled out. These include structural disorders of the urinary tract; urinary tract infection; neurologic deficits; disorders that increase the normal output of urine, such as diabetes; and disorders that impair the concentrating ability of the kidneys, such as chronic renal failure or sickle cell disease. A bladder volume of 300 to 350 ml (10–12 oz) is sufficient to hold a night’s urine. Normal bladder capacity (in ounces) is the child’s age plus 2 (up to age 14 years). In other cases, enuresis is influenced by emotional factors, although it is doubtful that they are causative factors. Parents report that these children sleep more soundly than other children; however, the depth of sleep has not been identified as the cause of nocturnal enuresis (Berry, 2006; Elder, 2011). Nocturnal enuresis has a strong familial tendency.


Therapeutic techniques used to manage nocturnal enuresis include medications, complementary and alternative medicine techniques such as hypnotherapy, restriction or elimination of fluids after the evening meal, avoidance of caffeinated and sugar-containing beverages after 4 PM, purposeful interruption of sleep to void, motivational therapy, and various devices designed to establish a conditioned reflex response to waken the child at the initiation of voiding (alarms).


Drug therapy is increasingly being prescribed to treat enuresis. Three types of drugs are used: tricyclic antidepressants (TCAs), antidiuretics, and antispasmodics. The selection depends on the interpretation of the cause. The drug used most frequently is the TCA imipramine (Tofranil), which exerts an anticholinergic action in the bladder to inhibit urination. The dosage and time of administration are individualized, and the drug is given in amounts sufficient to lighten sleep but not to cause wakefulness. Some practitioners prescribe low doses, which reduces bedwetting in two thirds of children. However, it is important to note that almost all children relapse when the medication is stopped. The suggested length of treatment is 6 to 8 weeks followed by gradual withdrawal over 4 weeks. Because overdosage of this drug is especially dangerous, caution parents about safe use and the need to keep supplies of the drug from the reach of younger siblings.


Anticholinergic drugs, especially oxybutynin, reduce uninhibited bladder contractions and may be helpful for children with daytime urinary frequency. Success has also been achieved with desmopressin acetate (DDAVP) nasal spray, an analog of vasopressin, which reduces nighttime urinary output to a volume less than functional bladder capacity. Typically, the child receives two sprays before bedtime. The medication is generally well tolerated but may cause nasal irritation or, rarely, headache or nausea. A preparation of desmopressin acetate is also available in tablet form. This preparation is as effective and safe as the nasal spray but avoids the problem of nasal irritation.


These drugs are considered second-line management, and parents should be cautioned not to think that these agents will cure the condition; parents are also advised of the drug’s side effects (Katz and DeMaso, 2011; Sethi, Bhargava, and Shipra, 2005).



Nursing Care Management

No matter what techniques are used, the nurse can help both children and parents understand the problem of enuresis, the treatment plan, and the difficulties they may encounter in the process. Essential to the success of any method is the supportive management of parents and their children. Both need encouragement and patience. The problem is discussed with both the parent and the child because all treatments involve and require the child’s active participation. In some treatment interventions, the child is in charge of the intervention; therefore, parents must learn to support the child rather than intervene themselves. For example, children can strip their wet linens, limit fluids, and use the toilet before bedtime. Parents should encourage the child to maintain a regular bowel evacuation regimen; constipation can contribute to nocturnal enuresis (Katz and DeMaso, 2011). A calendar with wet and dry nights may be helpful to motivate the child to stay dry and maintain a positive perspective on the problem; positive rewards are also helpful (Box 17-1).

Suggestions for Managing Nocturnal Enuresis*




Have child empty bladder immediately before going to bed.


Restrict fluids at nighttime meal to 7 to 8 oz (depending on age of child and previous activities).


Avoid fruit and juice drinks after 4 PM.


Avoid caffeinated or carbonated beverages after 4 PM.


Offer only sips of water before bedtime if child wants a drink before going to bed.


Allow child to wear regular sleepwear and avoid use of diapers or pull-ups.


Consider using environmental modifications such as a nightlight in the bathroom or bedroom (move furniture so child’s path to bathroom is not obstructed; avoid the top bunk of bunk beds).


Avoid scolding, threatening, embarrassing, or teasing child if a nighttime accident occurs.


Keep a calendar of wet and dry nights (e.g., use smiley or frowny faces and allow child to choose the appropriate “face” for the night).


Encourage parents to use positive reinforcements for dry nights.


Encourage the child to avoid holding urine during daytime.


If bedwetting occurs, have child participate in changing his or her bedclothing and personal clothing but explain that it is not a punishment for the accident.


Wake up child at a predetermined time every night and have him or her go to the bathroom; remain with child during the process and accompany child back to bed. (If bedwetting incidents occur, keep a diary of the times they occur based on the alarm and wake the child around that time.)


Encourage parents to maintain a positive attitude and to be patient with child.


Increase dietary fiber in child’s diet.


Encourage child to have a bowel movement on a regular basis (constipation may contribute to enuresis).


Encourage liberal intake of water throughout the daytime.



*These guidelines should be reserved for children ages 7 years and older.

Parents need to understand that punishment such as scolding, shaming, and threatening is contraindicated because of its negative emotional impact and limited success in reducing the behavior. Positive reinforcement of the desired behavior may be beneficial. Children need to believe that they are helping themselves, and they need to sustain feelings of confidence and hope. Many parents believe that enuresis is caused by an emotional disturbance and fear that they have somehow produced the situation by improper childrearing practices. They need reassurance that bedwetting is not a manifestation of emotional disturbance and does not represent willful misbehavior. Encourage parents to be patient, to be understanding, and to communicate love and support to the child.


Communication with children is directed toward eliminating the emotional impact of the problem, relieving feelings of shame and guilt and the burden of parental disapproval, building self-confidence, and motivating children toward independent control. More important, the nurse can provide consistent support and encouragement to help children through the inconsistent and unpredictable treatment process. Children need to believe that they are helping themselves and to maintain feelings of confidence and hope.


Parents should also be taught to observe for side effects of any medications used. All children with primary enuresis should be encouraged to void before bedtime and diapering should be avoided.



Encopresis


Encopresis is the repeated voluntary or involuntary passage of feces of normal or near-normal consistency in places not appropriate for that purpose according to the individual’s own sociocultural setting. The event must occur at least once per month for at least 3 months, and the chronologic or developmental age of the child must be at least 4 years. The fecal incontinence must not be caused by any physiologic effect, such as a laxative, or a general medical condition.


Primary encopresis is identified by age 4 years when a child has not achieved fecal continence. Secondary encopresis is fecal incontinence occurring in a child older than 4 years of age after a period of established fecal continence. The disorder is more common in boys than in girls.


One of the most common causes of encopresis is constipation, which may be precipitated by environmental change, such as having a new sibling, moving to a new house, changing schools, or even having to use new or unfamiliar toilet facilities. Chronic, severe constipation has a tendency to impair the usual movement and contractions of the colon, which can lead to fecal obstruction. Abnormalities in the digestive tract (e.g., Hirschsprung disease, anorectal lesions, malformations, rectal prolapse) and medical conditions such as hypothyroidism, hypokalemia, hypercalcemia, lead intoxication, myelomeningocele, cerebral palsy, muscular dystrophy, and irritable bowel syndrome are also associated with constipation, which can lead to encopresis. Voluntary retention of stool may also follow an incident of painful defecation (e.g., in a child with anal fissures). Involuntary retention may be produced by emotional problems caused by the encopresis, which sets up a fear–pain cycle and results in learned abnormal defecation patterns. Psychogenic encopresis, in which the soiling is caused by emotional problems, is often related to a disturbed mother–child relationship.


Normally, children and adolescents have one or two soft-formed stools per day. Children with soiling problems tend to form large-bore stools, which are painful to excrete. Therefore, they tend to avoid defecation and withhold stooling. Stool held in the rectum and sigmoid colon loses water and progressively hardens, which causes successively more painful bowel movements and a stretched rectal vault. Over time, the child will lose the urge to defecate on his or her own (Montgomery, 2008). A pain–retention–pain cycle is established. Many children have diarrhea or loose leakage in their clothing and pass small amounts of hard stool, which suggests leakage around an impaction.


Children may experience exacerbations with transitions in the school setting. Some reasons for developing retentive tendencies at this time are fear of using school bathrooms, a busy schedule, and the interruption of an established time schedule for bowel evacuation. Children may also react to stress with bowel dysfunction.


Therapeutic management consists of determining the cause of the soiling and using appropriate interventions to correct the problem. To determine the cause, perform a complete physical examination, including a rectal examination. Abdominal radiography may be done to determine the severity of impaction. Dietary modifications, stool softeners, and a toilet ritual that encourages the child to establish normal defecation are used. Fecal impaction is relieved by lubricants such as mineral oil; osmotic laxatives such as lactulose, sorbitol, or polyethylene glycol (PEG or MiraLax); and magnesium hydroxide. Customary dosages are usually insufficient. Mineral oil should be avoided in children who have dysphagia or vomiting to prevent aspiration. Dietary changes may be helpful, including elimination of milk and dairy products and consumption of increased amounts of high-fiber foods, such as fruits, vegetables, and cereals, as well as increased fluids (see Chapter 24). Behavior therapy may be indicated to eliminate any fear that has developed as a result of painful defecation. Psychotherapeutic intervention with the child and the family may become necessary.



Nursing Care Management

A thorough history of the soiling is essential, including when soiling began, how often it occurs and under what circumstances, and whether the child uses the toilet successfully at all. Because the parents and child are reluctant to volunteer information, direct questioning about the soiling is more successful.


Education regarding the physiology of normal defecation, toilet training as a developmental process, and the treatment outlined for the particular family is a prerequisite to a successful outcome. The regimen prescribed for stimulating elimination is explained to parents. Bowel retraining with mineral oil, a high-fiber diet, and a regular toileting routine is essential in treating encopresis or chronic constipation.


Encourage the child to sit on the toilet 10 to 15 minutes after meals for intervals of 10 to 15 minutes. Provide a quiet activity for the child and make sure the toilet is comfortable and in a nonthreatening environment. Placing a footstool below the feet may relax the abdomen and make the child more comfortable. Enemas may be needed for impactions in children with neurologic impairments and those with severe impactions, but long-term use prevents children from assuming responsibility for defecation. Initially, stool lubricants such as mineral oil may be given, but stimulant cathartics often cause abdominal cramps that can frighten children. Osmotic laxatives such as lactulose, sorbitol, or polyethylene glycol and magnesium hydroxide may be prescribed. Positive reinforcement such as giving stickers, praising the child, and awarding special activities may encourage the child to participate in the bowel regimen. Adequate fluid intake for the child is essential; many children play hard and forget to drink water or appropriate amounts of fluids, leading to a decrease in the formation of soft stool. Increase dietary fiber in meals and with fiber snacks that do not contain sugar (or <5 g). Many of the fast foods consumed by children, namely burgers, fries, and pizza, may also tend to be more constipating and should be minimized.


Family counseling is directed toward reassurance that most problems resolve successfully, although the child may have relapses during periods of stress, such as vacations or illness. If encopresis persists beyond occasional relapses, the condition needs to be reevaluated. Explain behavior modification techniques and assist the family with a plan suited to the particular situation (see Family-Centered Care box).
