The International Liaison Committee on Resuscitation (ILCOR) Neonatal Task Force reviews available resuscitation science every five years and develops guidelines which are integrated into educational programs such as the Neonatal Resuscitation Program (NRP). The most recent ILCOR Neonatal Task Force consensus guidelines were published in October 2015. The Canadian Paediatric Society’s NRP Steering Committee has reviewed ILCOR guidelines alongside the 7th edition (2016) NRP materials. Using a case-based approach, this practice point highlights the main changes relating to the delivery of NRP, within the Canadian context.

Every five years, international experts review the available resuscitation science and formulate guidelines relevant for clinical practice.  Recommendations from the International Liaison Committee on Resuscitation (ILCOR) Neonatal Task Force are then reviewed and integrated into educational programs such as the Neonatal Resuscitation Program (NRP). The 7th edition of the NRP textbook, released in 2016, integrates clinical and educational changes emerging from the 2015 guidelines.
To facilitate implementation of the 7th edition of NRP within the Canadian context, the Canadian Paediatric Society’s NRP Steering Committee has reviewed the published international guidelines and the 7th edition NRP guidelines and textbook. Using a case-based approach, the principal changes to delivery of neonatal resuscitation and training are described. The topics covered were chosen on the basis of their relevance to NRP providers.
The 2015 guidelines state that “there is insufficient published human evidence to suggest routine tracheal intubation for suctioning of meconium in non-vigorous infants born through MSAF”. In making this suggestion , the ILCOR Neonatal Task Force placed value on possible harm related to the procedure as well as potential benefits from the prompt initiation of resuscitation and assisted ventilation.
To prepare for such deliveries, it remains important to have a team member available who is skilled in neonatal intubation and advanced resuscitation. MSAF is a risk factor for abnormal transition and the non-vigorous infant may require mechanical ventilation. Avoiding routine intubation and tracheal suction of meconium does not preclude the need for advanced airway skills at some point(s) during resuscitation and stabilization.
The team should prepare by “briefing”, which includes assigning roles, checking equipment and discussing possible complications and management plans. Suction should still be prepared in the event that meconium presents obstruction to mechanical ventilation.
Resuscitation of the non-vigorous infant starts with initial steps of positioning, drying, stimulation and gentle oropharyngeal suction of the mouth and nose, as required.
When the heart rate is <100 bpm or the infant has ineffective respirations, positive-pressure ventilation (PPV) should be provided. The efficacy of ventilation should be assessed after 15 seconds of PPV by evaluating heart rate and chest rise.
When ventilation is ineffective, corrective steps should be instituted . The MR.SOPA mnemonic – Mask adjustment, Reposition airway, Suction mouth and nose, Open mouth, Pressure increase and Alternative airway – summarizes the corrective actions .
If thick meconium appears to be obstructing the infant’s action airway, endotracheal intubation and suction are still indicated. Endotracheal tube placement to provide PPV may also be required if initial corrective steps do not result in effective ventilation.
As with any resuscitation, appropriately trained personnel should be in attendance and a “brief” provided regarding equipment preparation, anticipated management and role assignment. When delivery of a preterm infant is expected, an appropriate environmental temperature should be maintained and the radiant warmer prepared.
In caring for infants <32 weeks’ gestational age in the delivery room, the 2015 ILCOR guidelines suggest: “a combination of interventions, which may include environmental temperature 23 to 25 degrees celsius, warm blankets, polyethylene wrapping without drying, cap and thermal mattress to reduce hypothermia”. Relevant history should be obtained from obstetric colleagues and plans made for delayed cord clamping if immediate resuscitation is not required. The oxygen blender should be pre-set to administer an initial concentration of oxygen, based on local guidelines. For preterm infants born at <35 weeks’ gestational age, recent ILCOR guidelines recommend a low initial oxygen concentration of 21% to 30%.
Following delivery, delayed cord clamping is appropriate for a minimum of 30 seconds if the baby is stable. Without drying, the baby should be placed in a polyethylene wrap. The infant’s temperature should be monitored using a servo-controlled radiant warmer with a temperature sensor, maintaining the baby’s temperature within the normal range (36.5°C to 37.5°C). Within the first minute of life, initial steps should be completed and assessment of heart rate and respiratory effort undertaken with delivery of PPV (if required).
Positive end-expiratory pressure (PEEP) is recommended when resuscitating the preterm infant, although recent guidelines do not recommend a particular device. If the baby is breathing spontaneously at an adequate respiratory rate, continuous positive airway pressure (CPAP) is suggested for initial respiratory support. CPAP pressures of 5 cm to 8 cm H2O may be considered.- Oxygen should then be provided according to recommended target saturations, as measured by a preductal saturation probe (NRP textbook, page 9). It is important to monitor ongoing respiratory status as subsequent intubation may be required due to respiratory failure or for administration of surfactant.
When the infant’s heart rate is less than 100 bpm, PPV should be provided. ‘MR.SOPA’ corrective steps should be incorporated if adequate ventilation is not achieved and oxygen should be increased to meet target saturations. The indications for initiating chest compressions and the recommended ratio of chest compressions to ventilation of 3:1 remain unchanged. The current NRP notes that while heart rate can be assessed by auscultation or pulse oximetry, electronic cardiac monitoring is the preferred method of assessment when administering chest compressions. Canadian recommendations for simplified epinephrine dosing remain at 0.01 mg/kg when administered intravenously and 0.1 mg/kg when administered endotracheally (0.1 mL/kg and 1 mL/kg respectively of 1:10,000 concentration). Of note, the maximum recommended endotracheal dose remains 0.3 mg (3 mL of 1:10,000 concentration). The indication for administering epinephrine is a heart rate less than 60 bpm despite effective ventilation and 60 seconds of chest compressions.
As with any complex resuscitation, preparedness and effective communication are integral to optimal team performance. Recurrent and frequent training should be considered; specifically, this training should be geared toward integrating specific task work or teamwork training, depending on learner needs.
One aim of the recent ILCOR review was to evaluate the delivery of resuscitation training in general. Studies have shown that retention of skills beyond six months is low for most formalized programs and that efficiency and effectiveness of skill delivery is reduced even two to four months after initial training.- Supplementary skills training can be used to improve knowledge and skill performance, but optimal timing for each type of learner remains unclear.
What is known is that to maximize learning, practice sessions should incorporate pre-determined objectives for specific tasks and the context in which these tasks are performed (i.e., case-based scenarios). Single skills, like mask ventilation, may only require a heart rate prompt, whereas tasks that require teamwork are best practiced in integrated ‘high fidelity’ simulations. Ideally, training should offer a level of realism that aligns with the complexity of tasks being taught and include the following stages: clarifying task objectives (briefing), practice performing the task(s), and reflecting on the experience (debriefing). Non-technical team skills can be developed through simulation or ‘mock code’ exercises.
An effective learning strategy may comprise frequent, brief practice sessions. For example, NRP providers could spend 5 minutes every month practising mask ventilation on a mannequin, while receiving heart rate and saturation prompts. Trainees would be expected to take corrective measures (e.g., using MR.SOPA) to achieve sufficient rise in heart rate and saturation. Repeated opportunities for focused practice would better enable individuals to achieve and retain mastery in the most important NRP skills, such as mask ventilation or the MR.SOPA routine. Short sessions of briefing and debriefing would further reinforce teamwork and task work. While there may some challenges to implementing frequent, brief practice sessions across large organizations, they should be encouraged at every opportunity.
Instructions for such practice sessions must be clearly shared with learners in focused and concise briefing notes. After simulation or skill station training, reflection should be promoted through debriefing. Debriefing questions specific to the learning objectives should be prepared in advance to help achieve this goal.
Neonatal resuscitation education should include completion of a formal NRP course every two years (at a minimum) but optimally – and whenever possible – should also include frequent training sessions to reinforce and improve skills, based on learner needs. The timing of sessions for each learner level deserves further study, but to maintain a high degree of realism, training exercises should include all members of the interprofessional team and take place in the clinical environment. Active learning, with clear objectives, integrating skills into simulation exercises and debriefing, will enhance individual and team performance.
The summary of key changes in Table 1 is based on 2015 ILCOR and 7th edition NRP guidelines.
