Newborn Suctioning: Step-by-Step Protocol for Healthcare Providers

Suctioning clears airway secretions in neonates who cannot clear them independently. Indications: meconium-stained fluid, excessive secretions, respiratory distress, apnea. Routine suctioning of vigorous term infants is no longer recommended (NRP 8th ed.).

Equipment

• Suction source (wall/portable) — set ≤100 mmHg (neonatal)
• Suction catheter: 6–10 Fr (size = ETT ID × 2, or per weight chart)
• Sterile saline (0.9%) for lavage
• Bulb syringe (for mouth/nose only, not trachea)
• PPE: gloves, mask, eye protection

Procedure: Oropharyngeal / Nasopharyngeal (Bulb or Catheter)

1. Hand Hygiene + PPE
2. Position: Sniffing position (slight neck extension), head neutral
3. Mouth First: Insert bulb/catheter to posterior pharynx; suction ≤5 sec while withdrawing
4. Nares: Insert catheter 3–5 cm; apply suction ≤5 sec while rotating/withdrawing
5. Alternate Sides: Allow recovery 15–30 sec between passes
6. Monitor: HR, SpO₂, color, tone throughout — stop if bradycardia <100, severe desat, apnea

Endotracheal Suctioning (If Intubated)

1. Pre-oxygenate 100% FiO₂ × 30 sec
2. Use closed-system (in-line) catheter if possible
3. Advance to pre-marked depth (cm at lip) — do not force past carina
4. Apply intermittent suction while rotating/withdrawing ≤5–10 sec
5. Re-oxygenate; assess HR, SpO₂, breath sounds
6. Instill 0.5–1 mL saline only if secretions thick (controversial — may disperse bacteria)

Critical Safety Limits

• Suction Pressure: ≤100 mmHg (preterm) / ≤120 mmHg (term)
• Duration: ≤5 sec (oral/nasal), ≤10 sec (ETT)
• Frequency: PRN only — not scheduled; minimize mucosal trauma
• Catheter Size: O.D. ≤ ½ ETT I.D. (prevents atelectasis)

Post-Suctioning Care

• Saline drops to nares if mucosal drying
• Reposition, comfort measures
• Document: time, indication, catheter size, depth, secretions (color/amount), vital signs, tolerance

Golden Rule: Suction only when clinically indicated. Gentle. Brief. Monitored.
