b. The pad emits insignificant levels of heat, so it can

be placed in direct contact with the infant to deliver

up to 35 mW/cm2

/nm of spectral irradiance, mainly

in the blue–green range (16).

c. The orientation of the fiberoptic fibers determines

the uniformity of emission and is unique to each of

the commercially available devices.

d. The main advantages of these systems are that,

while receiving phototherapy, the infant can be held

and/or nursed, thereby minimizing infant–parent

separation. In addition, covering the infant’s eyes is

not necessary, preventing further parental anxiety.

e. The main disadvantage of the fiberoptic pads is that

they cover a relatively small surface area and, therefore, have less efficacy compared to overhead

sources. They should not be used as the sole means

of providing phototherapy in an infant with significant hyperbilirubinemia (1,2,11).

f. These devices are often used as an adjunct to conventional overhead application of phototherapy to

provide “double” phototherapy (circumferential

phototherapy), which has greater efficacy because

greater body surface area is exposed to the light

(10,16).

7. Gallium nitride light-emitting diodes (LEDs)

a. These systems are semiconductor phototherapy

devices capable of delivering high spectral irradiance levels of >200 μW/cm2

/nm with very little generation of heat within a very narrow emission spectrum in the blue range (460 to 485 nm), with low

infrared emission and no ultraviolet emission

(10,17,18).

b. LEDs have a longer lifetime (>20,000 hours) and

have become cost-effective for use in phototherapy

devices. LEDs and compact fluorescent tubes are

equally efficacious in the management of hyperbilirubinemia (19).

D. Technique (Conventional

Phototherapy)

Intensive phototherapy is defined as the use of light in the

430- to 490-nm band delivered at 30 mW/cm2

/nm or higher

to the greatest body surface area possible (1,10).

1. Position the phototherapy unit over the infant to obtain

desired irradiance (10 to 40 μW/cm2

/nm). The maximal amount of irradiance achieved by the standard

technique is generally 30 to 50 μW/cm2

/nm. The distance of the light from the infant has a significant effect

on the intensity of phototherapy, and to achieve maximal intensity, the lights should be positioned as close as

possible to the infant. Fluorescent tubes may be

brought within approximately 10 cm of term infants

49 Phototherapy

Phototherapy is the most common therapeutic intervention

used for the treatment of hyperbilirubinemia (1).

Phototherapy causes three reactions: configurational and

structural isomerization of the bilirubin molecule and

photo-oxidation, leading to polar, water-soluble photoproducts that can be excreted in bile and urine without the need

for conjugation or further metabolism (2).

The aim of phototherapy is to reduce serum bilirubin

levels to decrease the risk of acute bilirubin encephalopathy

and the more chronic sequel of bilirubin toxicity, kernicterus (1). High-intensity phototherapy significantly reduces

the total serum bilirubin (TSB) and decreases the need for

exchange transfusion (3).

A. Indications

1. Clinically significant indirect hyperbilirubinemia.

Indications to start phototherapy in babies with hyperbilirubinemia vary depending on gestational age, birthweight, hours of life, presence of hemolysis, and other

risk factors such as acidosis and sepsis (1,4).

2. The TSB level must be considered when making the

decision to commence treatment, as there is significant

variability in laboratory measurement of direct bilirubin levels (5).

3. The American Academy of Pediatrics has published

clinical practice guidelines for phototherapy in

newborn infants at 35 weeks’ or more gestation (1)

(Fig. 49.1).

4. These guidelines do not apply to preterm infants <35

weeks’ gestation. Preterm infants are at higher risk of

developing hyperbilirubinemia compared to term

infants. Although guidelines have been proposed, the

decision to initiate phototherapy in this group of infants

remains variable and highly individualized (4,6)

(Table 49.1).

B. Contraindications

1. Congenital porphyria or a family history of porphyria is

an absolute contraindication to the use of phototherapy. Severe purpuric bullous eruptions have been

described in neonates with congenital erythropoietic

porphyria treated with phototherapy (7).

2. Concomitant use of drugs or agents that are photosensitizers is also an absolute contraindication (8).

3. Concurrent therapy with metalloporphyrin heme oxygenase inhibitors has been reported to result in mild

transient erythema (9).

 


4. Although infants with cholestatic jaundice may develop

the “bronze baby syndrome” when exposed to phototherapy (see H), the presence of direct hyperbilirubinemia is not considered to be a contraindication (1).

However, because the products of phototherapy are

excreted in the bile, the presence of cholestasis may

decrease the effectiveness of phototherapy.

C. Equipment

In order to have an understanding of the equipment available for phototherapy, it is necessary to be familiar with the

terminology involved (10).

1. Spectral qualities of the delivered light (wavelength

range and peak). Bilirubin absorbs visible light within

the wavelength range of 400 to 500 nm, with peak

absorption at 460 ± 10 nm considered to be the most

effective (2).

2. Irradiance (intensity of light), expressed as watts per

square centimeter (W/cm2

), refers to the number of

photons received per square centimeter of exposed

body surface area.

3. Spectral irradiance is irradiance that is quantitated

within the effective wavelength range for efficacy and is

expressed as mW/cm2

/nm. This is measured by various

commercially available radiometers. Specific radiometers are generally recommended for each phototherapy

system, because measurements of irradiance may vary

depending on the radiometer and the light source

(1,10).

A variety of phototherapy equipment devices exist

and may be free-standing, attached to a radiant warmer,

wall-mounted, suspended from the ceiling, or fiberoptic

systems. These in turn may contain various light sources

48 Drainage of Superficial Abscesses

A. Definitions

A Superficial abscess is

1. A localized collection of pus resulting from bacterial

organisms that cause necrosis, liquefaction, accumulation of leukocytes and debris, which presents as a fluctuant soft tissue swelling that may have associated erythema and induration (Fig. 48.1) (1–5)

2. In newborns, usually caused by invasion of local bacterial flora (2), direct inoculation, (e.g., animal bites) (6)

or skin piercing (7)

B. Indications

1. To establish free drainage of contents from a superficial

abscess

Surgical incision and drainage is the definitive

treatment for soft tissue abscesses. Antibiotic therapy

alone is ineffective in the setting of localized abscess

(1,2,8–11)

2. To identify pathogens and direct antimicrobial therapy

if needed (2,12–16)

3. To differentiate infectious from noninfectious lesions

(15,17,18)

C. Contraindications

1. Carefully identify and avoid

a. Cephalohematoma

b. Hemangioma

c. Cystic hygroma

d. Encephalocele

2. Avoid premature incision and drainage of abscesses that

have not yet fully matured (i.e., in the initial stages of

induration and inflammation prior to formation of pus)

(4). This may lead to

a. A noncurative intervention

b. Possible extension of infectious process

c. Bacteremia

Premature incision may be avoided by the use of

ultrasound with or without diagnostic needle aspiration (19,20).

D. Equipment

Sterile

1. Gloves and gown

2. Antiseptic swabs or cup containing antiseptic solution

3. 1-mL syringe

4. Nonbacteriostatic, isotonic saline without preservative

5. 23-gauge needle

6. 2- × 2-inch gauze squares

7. Scalpel with no. 11 blade

8. Cotton-tipped culture swab

9. Mosquito hemostat

10. 0.5-inch, fine-mesh, plain gauze

Nonsterile

1. Ethyl chloride spray as topical anesthetic. (For larger

lesions, local anesthesia with lidocaine may be used.)

2. Mask and cap

3. Adhesive tape

E. Precautions

1. Use appropriate isolation techniques to safeguard other

infants.

 


Buried penis is usually the result of inappropriate

circumcision in a chubby baby with a small or concealed penis. Excessive removal of skin should be

treated with application of antiseptic (iodophor) daily

and not with grafting or burying the penis in scrotum.

The skin will grow back.

15. Recurrence of pneumothorax (27)

16. Reaction to epinephrine used to control bleeding

a. Tachycardia

b. Local vasospasm (may lead to necrosis of the glans)

17. Complications due to local anesthetic

a. Methemoglobinemia has been reported following

exposure to prilocaine, procaine, benzocaine, and

lidocaine (28).

b. Hematoma; those reported in neonates have

resolved spontaneously.

c. Seizures (29)

18. Mechanical problems with Gomco clamp (30)

a. Loss of a part

b. Warping of the plate after multiple use

c. Breakage of arm during tightening

d. Grooves and nicks in bell at junction of bell and plate

f. Check that prepuce is freed from entire surface of

glans. Complete separation if necessary.

11. Complete circumcision using method of choice.

a. Use of circumcision clamp

(1) Check clamp to ensure that all parts are present,

fit well, and are in good working order.

(2) Assemble clamp, ensuring that yolk (arm)

articulates correctly with baseplate.

(3) Draw prepuce backward gently to expose

entire glans penis.

(4) Break down all residual adhesions, and observe

position of meatus. If meatus is abnormal,

cease at this point.

(5) Sponge glans dry with gauze swabs.

(6) Select stud (bell) of adequate size (see C), and

place over glans (Fig. 47.4A).

(7) Pull prepuce over stud.

(a) Approximate edge of dorsal slit. (A sterile

safety pin may be used.)

(b) Observe amount of skin remaining under

baseplate for accuracy.

Proper placement of prepuce over stud

is essential. Pulling too taut may lead to

removal of excessive penile skin. Insufficient

tension may lead to incomplete circumcision.

(8) Place baseplate of clamp over stud (with pin

perpendicular to shaft of penis) so that prepuce

is sandwiched between them (Fig. 47.4B).

(9) Continue to pull upward on stud until entire

prepuce is drawn through baseplate and stud

engages with baseplate.

(10) Hook yoke (arm) of clamp under side arms on

shaft of stud and bolt firmly to baseplate, after

checking position of prepuce between stud

and baseplate (Fig. 47.4C).

(11) Remove safety pin.

(12) Wait 10 minutes.

Hemostasis is produced by pressure between

baseplate and rim of stud. If the clamp is

removed before 10 minutes has elapsed, wound

edge hemostasis may be inadequate. If significant bleeding occurs during the procedure,

remove the device and search for bleeding

vessel—avoid blindly placing sutures.

(13) Remove prepuce with scalpel held parallel to

and flush with upper surface of baseplate. Never

use electrocautery; however, use of an ultrasound dissection scalpel has been described as a

safe alternative to electrocautery (6).

(14) Loosen bolt on clamp and remove.

(15) Optional: Dress with loose, noncircumferential sterile gauze impregnated with Vaseline.

Gough and Lawton (7) have shown that the

addition of tincture of benzoin to the dressing

adversely affected wound healing and the

addition of topical antibiotic did not produce

better results than those achieved with ordinary paraffin gauze.
