Assessing and Managing Newborn Weight Loss

 

AAP Breastfeeding Guideline

 

AAP Breastfeeding Guideline

• The AAP recommends exclusive breastfeeding for the first 6 months.
• The AAP supports continued breastfeeding along with appropriate complementary foods introduced at about 6 months, as long as mutually desired, for 2 years or beyond.

Benefits of Breastfeeding

• For mothers: bonding, depression, hemorrhage, weight management, reduces breast/ovarian cancer risk, financial benefits.
• For infants: bonding, growth, digestion, immunity, brain development.

Risks of Unnecessary Formula Supplementation

• Decreased breast milk supply: Formula may suppress the mother's milk production.
• Overfeeding, spitting up, excess weight gain: Formula can lead to these issues if not used appropriately.

Formula Supplementation

• Consider formula supplementation if the newborn is experiencing significant weight loss:
  • Low maternal breast milk volume
  • Increased caloric and nutrient needs due to prematurity, congenital heart disease, etc.
• Exclusive formula feeding is indicated for:
  • Certain medical conditions requiring soy formula, like galactosemia
  • Adoption
  • Mother's fully informed decision to solely formula feed

Assessing Feeding Adequacy in Newborns

• Objective: Assess feeding adequacy during the newborn visit.
• Factors to consider:
  • Weight trend since birth
  • Number of feedings per day
  • Hunger and satiety cues
  • Number of stools and wet diapers per day
  • Color and consistency of stools

Normal Weight Loss in Newborns

• Nadir: Typical weight loss of 7-10% in the first few days.
• Weight regain: Birth weight regained by 10-14 days old.
• Subsequent weight gain: Gain 15-30 grams (0.5-1 ounce) per day after regaining birth weight.

Reasons for Newborn Weight Loss

• Diuresis: Newborns excrete excess extracellular fluid to maintain hydration and electrolyte balance.
• Colostrum: Early breast milk is low in water and high in protein, contributing to weight loss.
• Mature breast milk: Fully comes in around 48-72 hours after delivery, later for C-sections due to stress.

Excess Weight Loss in Newborns

• Definition: Loss of more than 10% of birth weight.
• Consequences: Can lead to hypoglycemia, dehydration, hypothermia, jaundice, and lethargy.
• Impact: Can lead to feeding difficulty and further weight loss, creating a downward spiral.

Feeding Frequency and Cues

• Frequency: Newborns should feed 8-12 times per day (every 2-3 hours).
• Duration: 10-15 minutes per breast.
• Wake for feedings: Wake the baby on their own for most feedings.
• Hunger cues: rooting, lip smacking, sucking on hands, crying (late sign).
• Satiety cues: stopping sucking, closing mouth, pulling away, turning head away, falling asleep.

Stools and Wet Diapers

• Normal: 6+ wet diapers and 3+ stools per day.
• Transitional stools: Expected by 3-5 days old, yellow and seedy, indicating bilirubin excretion.

Managing Excess Weight Loss in Breastfed Infants

• Continue breastfeeding: Encourage continued breastfeeding.
• Temporary formula supplementation: Supplement with formula to address weight loss.
• Donor breast milk: Consider donor breast milk from a bank, but it can be challenging to obtain outpatient.
• Lactation consultant: Seek guidance from a certified lactation consultant.
• Weight monitoring: Check weight every 2-3 days until weight loss stops and daily weight gain of 0.5-1 ounce resumes.

Managing Excess Weight Loss in Formula-Fed Infants

• Assess formula preparation: Ensure correct formula preparation to avoid dilution:
  • Ready-to-feed: Do not add water.
  • Concentrate: Add equal parts water and concentrate.
  • Powder: Add 1 level scoop of powder to 2 ounces of water.
• Assess intake volume:
  • Approximately 1 ounce per week of life per feeding for the first four weeks
  • At least 24 ounces per day by the end of the first month
  • Aim for 100 kcal/kg/day (1 ounce of formula = 20 kcal)
• Assess formula access: Consider store brands, which are safe and nutritious; if eligible, sign up for WIC.

Postpartum Depression Screening and Management

• Screening: Administer a validated postpartum depression screening tool at all well visits through 6 months of age.
• Validated screening tools:
  • Edinburgh Postpartum Depression Scale
  • Patient Health Questionnaire-9 (PHQ-9)
• Referral for treatment: Refer mothers who screen positive for treatment.

Social Determinants of Health

• Definition: Social and economic factors that influence health.
• AAP resources: The AAP offers resources for providers.
• Assessment: Ask about:
  • Medical insurance
  • Food security
  • Safe and stable housing
  • Mother's employment
  • Childcare
  • Mother's social support system
  • Domestic violence

Safe Sleep Recommendations

• Key message: Reduce infant deaths from unsafe sleep environments.
• Room sharing: Room sharing for the first 6 months of life.
• Separate sleep surface: No co-sleeping; infant should sleep on a separate surface within the parents' room.
• Sleep surface:
  • Flat surface (not inclined)
  • Firm surface
• Bedding: Avoid soft objects, loose bedding, bumpers.
• Sleep position: Back to sleep, tummy to play.
• Overheating: Avoid overheating the infant.
• Other recommendations:
  • Breastfeeding
  • Vaccination
  • Avoid smoking, alcohol, and drugs
  • Consider a pacifier
  • Commercial cardiorespiratory monitors do not reduce risk of SIDS

Circumcision Care

• Purpose: Elective procedure for most newborns, reducing the risk of urinary tract infections (UTIs) in infancy and penile cancer, HIV, and other sexually transmitted infections (STIs) later in life.
• Postoperative care:
  • Petroleum gauze dressing for 4 hours post-op
  • Petroleum jelly application with each diaper change for 7-10 days until healed
  • Gentle foreskin retraction with each diaper change when healed to prevent adhesions
  • Sponge baths only until healed
• Signs of infection: Sores, yellow crust, purulent discharge, poor healing, and/or fever

Normal Newborn Skin Changes

• Peeling skin: Normal for the first 4-6 weeks; self-resolves; not itchy or painful.
• Erythema toxicum neonatorum: Normal for the first few weeks; self-resolves; not itchy or painful; appears as flea bites on hair-bearing skin surfaces; papules contain eosinophil-rich infiltrate.
• Cradle cap (infant seborrheic dermatitis): Normal between 2 weeks and 12 months of age; self-resolves; not itchy or painful; erythematous papules and scaliness on any skin surface with oil glands; due to the interaction of overactive oil glands and Malessezia furfur* yeast on the skin.

Developmental Dysplasia of the Hip (DDH)

• Definition: Congenital malformation where the femoral head subluxates out of the acetabulum.
• Spectrum of severity: Mild cases may go undetected and not become symptomatic until adulthood.
• Risk factors: Family history, female sex, breech presentation in the third trimester, incorrect swaddling (legs extended).
• Consequences of late detection/treatment: Limp, limb length discrepancy, limited hip abduction, premature osteoarthritis.

Examining for DDH

• Visual assessment: Observe for asymmetric abduction, asymmetric skin folds, asymmetric prominence of the trochanter, and limb length discrepancy.
• Galeazzi sign: Femur on the side with DDH appears shorter, but the femur is not actually shorter.
• Barlow maneuver: Attempts to dislocate the hip.
• Ortolani maneuver: Attempts to relocate the hip.
• Manuever timing: Should not remain positive beyond 6 weeks of age; order imaging if still positive; perform maneuvers at all well visits until the infant is walking.

Diagnosing and Treating DDH

• Imaging: Hip ultrasound between 6 weeks and 4 months of age; Hip X-ray (AP and frog leg views) between 4-6 months of age.
• Referral: If risk factors or positive/inconclusive exam by 6 weeks, refer to Pediatric Orthopedics.
• Treatment:
  • Hip abduction brace
  • Surgical correction for failed brace

Fevers in Infants Under 60 Days Old

• Definition: Rectal temperature ≥ 100.4˚F (≥ 38˚C).
• Rectal temperature: Recommended for infants under 60 days old due to better accuracy.
• Medical emergency: Fever is considered an emergency in infants < 60 days old.
• Reason: Need to rule out serious bacterial infections, such as UTIs, bacteremia, and meningitis.
• Parent guidance: Counsel families to call immediately if their infant develops a fever and to avoid giving Tylenol or fever-reducing medications until a medical assessment is performed.

Car Safety Seat Recommendations

• Importance: Vehicle crashes are a leading cause of death and disability in children.
• AAP recommendation: Use a rear-facing car safety seat until at least 2 years old.
• Rear-facing safety: Protects the cervical spine by absorbing the force of a collision.
• Forward-facing risks: The head is thrown forward, which poses risks to infants and toddlers with large, heavy heads and weak neck muscles.

Medical Triads in Surgery

 

Hoover’s sign (Neurological)

1. Core Concept

Hoover's sign is a physical exam maneuver used to help differentiate organic leg weakness from functional (non-organic) leg weakness , often seen in Functional Neurological Disorder (FND) or conversion disorder.

2. The Principle

The test is based on a normal, involuntary synergistic movement: when a supine patient flexes one hip (by trying to raise that leg), they automatically and involuntarily extend (push down) the contralateral hip to brace themselves. This is known as a "associated movement."

• Organic Paralysis: This associated movement is absent. The patient cannot voluntarily lift the "good" leg, and the "bad" leg does not push down.
• Functional Paralysis: This associated movement is preserved but disconnected from voluntary effort. The patient doesn't voluntarily push down with the "bad" leg when asked to lift the "good" one, but the automatic movement occurs.

3. Indications for Use

• A patient presenting with unilateral leg weakness or paralysis.
• When the clinical picture is inconsistent or there are positive signs of a functional disorder (e.g., give-way weakness, bizarre gait).
• To provide objective evidence for a functional component to the weakness.

4. How to Perform the Test (Step-by-Step)

Position: Patient lies supine on an examination table.

Part A: Testing the "Bad" (Weak) Leg

1. Place your hand under the heel of the patient's "good" (strong) leg. This is your sensing hand.
2. Ask the patient to press down with their "bad" (weak) leg ("Press your weak leg down into the bed as hard as you can").
3. Normal/Organic Finding: You will feel firm downward pressure in your sensing hand under the good heel (the associated movement of hip extension).
4. Functional Finding: You will feel little or no pressure in your sensing hand, indicating a lack of genuine effort from the "bad" leg.

Part B: Testing the "Good" (Strong) Leg

1. Keep your sensing hand under the heel of the "bad" (weak) leg.
2. Ask the patient to lift their "good" (strong) leg ("Lift your good leg up off the bed, keeping your knee straight").
3. Normal/Organic Finding: You will feel firm downward pressure in your sensing hand under the weak heel (the involuntary associated movement).
4. Functional Finding: You will feel little or no pressure under the "bad" heel. The patient may even flex the "bad" hip (a true paradox), demonstrating that the motor pathways are intact but not being used voluntarily.

5. Interpretation of Results

Test Component	Normal / Organic Weakness	Functional Weakness
Press down with BAD leg	Positive reinforcement: Strong downward pressure felt under the GOOD heel.	Negative: No pressure felt under the good heel.
Lift up with GOOD leg	Positive reinforcement: Strong downward pressure felt under the BAD heel.	Negative: No pressure (or paradoxical flexion) felt under the bad heel.

A "Positive Hoover's Sign" for functional weakness is when the test is negative—i.e., the expected associated movement is absent.

6. Key Advantages

• Objective: Provides a physical sign, not just a subjective report.
• Reliable: Has good inter-rater reliability when performed correctly.
• Bedside: Requires no special equipment.
• Diagnostically powerful: A clear positive sign is strongly suggestive of a functional etiology.

7. Important Caveats & Pitfalls

• False Positives: Can occur with pain (e.g., severe back or hip pain), apraxia, profound weakness (e.g., complete spinal cord injury), or lack of patient understanding.
• False Negatives: A savvy patient may learn to fake the sign.
• Not a Standalone Test: Must be used in the context of a full neurological exam and history. It is one of several "positive signs of functional weakness."
• Communication is Key: Deliver instructions clearly and neutrally. Avoid implying you are testing for "faking."

8. Classic Phrasing for Note

"Hoover's test was positive for functional weakness: absence of expected hip extension in the right leg when flexing the contralateral hip."

ACOG 2025 RECOMMENDATION on Delayed Cord Clamping

The American College of Obstetricians and Gynecologists (ACOG) has issued new guidelines on deferred umbilical cord clamping in preterm babies, based on evidence showing that such delays save lives.

• Defer umbilical cord clamping for at least 60 seconds in preterm neonates born before 37 weeks of gestation who do not require immediate resuscitation.
• In neonates born between 28 0/7 and 36 6/7 weeks of gestation, when deferred clamping is not performed, umbilical cord milking is a reasonable alternative to immediate clamping to improve hematologic outcomes. 

 

 

Comparison of Early vs. Delayed Cord Clamping           

 

Parameter	Early Cord Clamping (ECC)	Delayed Cord Clamping (DCC)
Timing	Within 15–30 seconds after birth	≥30 seconds to ≥120 seconds (often 60–180 sec)
Placental transfusion	Limited	Enhanced (20–40 mL/kg additional blood volume)
Hemoglobin & Hematocrit levels	Lower	Higher
Iron stores	Reduced	Improved (lower risk of iron-deficiency anemia)
Need for RBC transfusion	Higher, especially in preterm infants	Lower, particularly <32 weeks gestation
Neonatal jaundice risk	Lower	Slightly increased (due to higher blood volume)
Polycythemia & blood viscosity	Less frequent	Slightly increased risk
Intraventricular hemorrhage (IVH)	No reduction	Reduced incidence in preterm neonates
Necrotizing enterocolitis (NEC)	No protective effect	Lower incidence in preterm infants
Cardiovascular stability	Less optimal	Improved BP regulation and perfusion
Maternal outcomes	Historically preferred for rapid resuscitation	No adverse impact; safe with proper monitoring
Clinical recommendation	Outdated standard	Recommended by WHO, ACOG, and other bodie

 📌 Note: While DCC offers substantial neonatal benefits, especially in preterm births, it requires readiness for jaundice monitoring and institutional protocols to support safe implementation.

IV Drip Rate: Formula.

What is IV drip rate? 

IV drip rate describes the rate at which an intravenous infusion is administered in drops per minute.

Use of an IV pump to automatically control the rate of infusion is now common in most medical settings in the United States; however, an IV pump may not be available in some settings/emergencies. In these situations, it is important that nurses know how to calculate the IV drip rate and set the rate of infusion using the IV tubing roller clamp.

How to select the correct tubing type

Factors such as client age and size will guide selection of IV tubing. Different tubing types deliver a larger or smaller number of drops per milliliter. Pediatric clients are very sensitive to fluid volume, so microdrip tubing is used to tightly control fluid volume administration (60 gtt(mL). Macrodrip tubing (10, 15, or 20 gtt/mL) is typically used for adult clients.

What is the drop factor? 

The drop factor (or drip factor) refers to the number of drops (gtts) that make up one milliliter of fluid. Specific to the type of IV tubing being used (typically indicated on the packaging), it is used to calculate the flow rate for manual IV infusions. 

Example order for IV infusion

Typically, the order will include the volume of medication or fluid to be infused and either a rate per hour or the overall duration of the infusion.

It is your job as the nurse to use this information to determine the IV drip rate in gtt/min.

How to calculate IV flow rate: Drops per minute 

We are using the example order of 0.9% normal saline, 1000 mL IV over 8 hr for the calculation. The drop factor is 10 gtts/mL.

Step 1: Convert time units to get the total infusion time in minutes 

Total infusion time in minutes: The order states 8 hours, which is calculated by multiplying 60 minutes x 8 hours, equaling 480 minutes overall. 

Step 2: Calculate gtt per minute with the IV drip rate formula

Formula:

• The total volume is given in the doctor's order. 
• The drop factor is determined by the use of the correct tubing, which is required for the calculation.
• The time is the overall infusion time in minutes. 

 

Since you can't actually administer a fraction of a drop, if you get a fraction as a result, round to the nearest whole number. 

How to set the drip rate

To set the IV drip rate, count the drops as fluid enters the drip chamber. Adjust the roller clamp until you count the correct number of drops entering the chamber per minute (21 for our example above). For safety, label IV bag with the ordered rate and time the hourly markings for infusion.
