Introduction

  • The transport of a sick neonate is a highly critical event that requires meticulous planning and execution.
  • Whenever possible, in utero transfer of the mother to a higher-level facility is preferable to postnatal transport of a sick neonate.
  • Safe transport requires equipped intensive care unit ambulances, trained manpower, structured communication, and timely referral protocols.
  • The mobile environment places the baby at a high risk of destabilization due to movement, noise, vibration, and limited space.

Types Of Neonatal Transport

  • Forward or Escalation Transfer: Transferring a neonate from a lower-level birth facility to a regional tertiary neonatal intensive care unit (NICU).
  • Reverse Transfer: Transferring a recovering infant back to their birth hospital or a facility closer to home for ongoing step-down care.
  • Wait and Return: A temporary transfer to a higher facility for specific investigations or treatments, followed by a return to the base hospital.
  • Intra-hospital Transport: Moving the baby within the same hospital, such as from the delivery room to the NICU, operating theater, or radiology suite.

Indications For Transport

  • Neonates are transported based on their need for advanced respiratory, cardiovascular, surgical, or specialized medical care.
CategorySpecific Clinical Conditions
Extreme PrematurityBirth weight less than 1500 g or gestation less than 32 weeks.
Respiratory FailureSevere respiratory distress needing continuous positive airway pressure (CPAP), mechanical ventilation, or inhaled nitric oxide (iNO).
NeurologicalPerinatal asphyxia or hypoxic-ischemic encephalopathy (HIE) requiring therapeutic hypothermia, refractory seizures.
CardiovascularSuspected congenital heart disease, arrhythmias, or unresponsive shock.
Surgical EmergenciesMajor congenital malformations, necrotizing enterocolitis, or intestinal obstruction.
Metabolic/OthersSevere hyperbilirubinemia needing exchange transfusion, refractory hypoglycemia, or inborn errors of metabolism.

Organization Of Transport Services

The Transport Team

  • Transport teams should ideally consist of trained personnel such as neonatal nurses, respiratory therapists, and physicians.
  • Unit-based teams: Staffed by nurses and doctors working in the NICU who are deployed when a transport request arises.
  • Dedicated teams: Staffed entirely separately from the NICU specifically for transport coverage.

Mode Of Transportation

  • Ground ambulance: The most common modality. It offers a larger workspace, the ability to carry multiple team members, and the option to pull over for critical interventions.
  • Rotor-wing (Helicopter): Suitable for rapid, hospital-to-hospital transport over moderate distances.
  • Fixed-wing (Airplane): Best suited for long-distance transport, requiring ground ambulances at both ends of the flight.

Essential Equipment And Medications

  • The team must carry all required equipment and medications in pre-packed bags with strict checklists.
CategoryEquipment And Supplies
Incubation & MonitoringTransport incubator with ventilator, pulse oximeter, temperature probes, and electrocardiogram leads.
Airway & BreathingOxygen cylinders, blender, T-piece resuscitator, self-inflating bags, laryngoscopes, endotracheal tubes, and suction machine.
Vascular Access & FluidsIntravenous cannulas, umbilical vein catheters, infusion pumps, normal saline, 10% dextrose.
Essential MedicationsEpinephrine, inotropes (dopamine/dobutamine), phenobarbitone, antibiotics, surfactant, and Prostaglandin E1.

Pre-Transport Stabilization (TOPS Approach)

  • The transport team must stabilize the baby before undertaking the risky journey.
  • Severity scoring systems like the Transport Risk Index of Physiologic Stability (TRIPS) can predict the occurrence of critical illness.
  • Stabilization focuses on the "TOPS" mnemonic: Temperature, Oxygenation, Perfusion, and Sugar.

Temperature

  • Ensure a neutral thermal environment.
  • Use a transport incubator, plastic wraps for extremely premature babies, or skin-to-skin contact (Kangaroo Mother Care) for stable babies.
  • Servo-controlled active cooling should be initiated and maintained for infants meeting the criteria for therapeutic hypothermia.

Oxygenation And Airway

  • Ensure airway patency and secure the endotracheal tube properly, as dislodgement is common during movement.
  • Provide adequate oxygenation and ventilation, using CPAP or mechanical ventilation as indicated.

Perfusion And Circulation

  • Establish stable vascular access, preferably through an umbilical venous catheter or a secure peripheral line.
  • Treat shock with normal saline boluses (10 ml/kg) and initiate vasoactive infusions if required.

Sugar And Metabolic

  • Ensure adequate blood glucose concentrations.
  • Correct hypoglycemia before transport and maintain an ongoing intravenous dextrose infusion.

Specific Clinical Conditions During Transport

Respiratory Distress Syndrome (RDS)

  • If a preterm infant requires intubation for mechanical ventilation, exogenous surfactant should be administered before transport.
  • Anticipate rapid changes in lung compliance post-surfactant and adjust ventilatory support to minimize the risk of pneumothorax.

Hypoxic Respiratory Failure And PPHN

  • Ensure optimal lung recruitment but strictly avoid hyperventilation.
  • Transport teams should be prepared to institute inhaled nitric oxide if available.

Congenital Heart Disease

  • For infants with suspected ductal-dependent lesions, initiate a Prostaglandin E1 (PGE1) infusion prior to transport.
  • Because PGE1 can cause apnea, the threshold for elective intubation before transport should be low.

Surgical Conditions

  • An orogastric tube must be placed and kept on continuous drainage.
  • This is critical for intestinal obstruction or congenital diaphragmatic hernia, especially during air transport.

Physiologic Considerations Of Air Transport

  • Alveolar hypoxia (Dalton's law): As altitude increases, barometric pressure decreases, causing a fall in alveolar oxygen tension. The fraction of inspired oxygen (FiO2) must be increased to maintain saturation.
  • Gas expansion (Boyle's law): As barometric pressure drops, trapped gases expand. This mandates the pre-flight drainage of a pneumothorax and continuous venting of the stomach.

Communication, Counseling, And Documentation

  • Hospitalization and transport precipitate a major emotional crisis for the family.
  • Allow parents to see and touch their infant prior to the transfer.
  • Thoroughly explain the clinical condition, the reason for transfer, and the anticipated care during transport.
  • Obtain formal written consent for the transfer and any anticipated procedures.
  • Document the infant's health status, interventions performed, and vital signs on a standardized hand-over checklist.
  • Facilitate a four-way communication stream between the referring team, the receiving team, the transport team, and the baby's family.
  • Following the transport, the team must call the referring hospital to provide feedback on the baby's arrival condition.
