Adaptations have been proposed for resuscitation of infants born to women with COVID-19, to protect health care providers, maintain infection control, and limit post-natal transmission. Changes especially impact respiratory procedures, personal protective equipment (PPE) use, resuscitation environments, teamwork, and family involvement. Adding viral filters to ventilation devices and modifications to intubation procedures might hinder effective ventilation. PPE could delay resuscitation, hinder task performance, and degrade communication. Changes to resuscitation locations and team composition alter workflow and teamwork. Physical distancing measures and PPE impede family-integrated care. These disruptions need to be considered given the uncertainty of vertical transmission of SARS-CoV-2.
COVID-19 is an evolving pandemic caused by the novel betacoronavirus SARS-CoV-2 (1). While mortality is associated with advanced age and co-morbidities, pregnant women can be affected (2). It is unclear how much maternal COVID-19 infection contributes to fetal distress, preterm labor, or indications for early delivery (3). Suspected vertical transmission has been reported (4) but the risk appears low (5).
Current neonatal resuscitation guidelines include recommendations on equipment, procedures, team composition, and teamwork (6). Adaptations have been proposed for resuscitation of infants born to women with suspected or confirmed COVID-19, to protect health care providers (HCPs), limit post-natal transmission, and maintain infection control (7). Neonatal resuscitation may be especially impacted by changes in (i) respiratory support, (ii) personal protective equipment (PPE), (iii) resuscitation environment, (iv) team-based activities, and (v) family involvement (Table 1). In this article, we explore these potential disruptions and propose strategies to evaluate and minimize their impact.
Ventilation Equipment and Procedures
Mask ventilation and endotracheal intubation are aerosol generating procedures (AGP) critical to neonatal resuscitation (6). The risk of transmitting SARS-CoV-2 to HCPs during AGPs is estimated from observational studies in other viral infections (8). Modifications to ventilation practices during neonatal resuscitation have been proposed to protect HCPs during AGPs, based on limited evidence on vertical transmission and aerosolization of SARS-CoV-2 (7, 9).
General COVID-19 resuscitation guidelines recommend the use of viral filters on mask ventilation devices to decrease risks to HCPs (9). The effectiveness of viral filters depend on mask seal, filter, and device type (e.g., self-inflating bag, flow-inflating bag, and T-piece resuscitators), flow rate, filter integrity, and patient factors (10). Experience with filters come from ventilated patients in intensive care or anesthetic environments (11) Filters increase airway resistance, dead space and CO2 retention, and obstruct the ventilation circuit if soiled (10, 11). Filter complications may be exaggerated in neonates due to their lower tidal volume, minute ventilation, and functional reserve (11). Smallest filters are only rated for infants weighing 3 kg and above. Manufacturers have warned against fitting of viral filters to their devices, as these configurations are untested (12). Further testing is needed to determine how filters affect mask ventilation in neonates. Another strategy to reduce aerosolization during mask ventilation is to minimize mask leak. Two-person mask application reduces mask leak but increases HCP exposure; respiratory function monitoring detects mask leak but requires additional training and equipment (13).
Endotracheal intubation is a confirmed risk factor for HCP infection in the previous SARS (Severe Acute Respiratory Syndrome) outbreak (14). Given the low likelihood of vertical transmission with the SARS-CoV-2, the need for COVID-19 intubation precautions during neonatal resuscitation in the delivery room is likely low. Pre-emptive intubation to avoid mask ventilation (as suggested in adult settings) may lead to excess intubations and intubation attempts in neonates. The use of videolaryngoscopes and cuffed endotracheal tubes further minimize risk during neonatal resuscitation, but are significant practice changes for many centers. At our center, we have not altered the indications, timing, or procedure for intubation during neonatal resuscitation of COVID-19 exposed infants. Nonetheless, concerns with this procedure may cause deviations from established practice.
Changes to respiratory equipment or indications for their use may affect HCP workload, introduce equipment uncommon in neonatal care, or lead to neonates receiving supports or interventions unsuited to their needs. Examples include: using low flow nasal canula (LFNC) instead of nasal CPAP (constant positive airway pressure) to avoid AGPs, intubating with cuffed endotracheal tubes, or inserting viral filters in respiratory circuits. The impact of these approaches may be unpredictable. If vertical transmission is unlikely (5), the potential harms of these variations may outweigh potential benefits, particularly if HCPs don PPE.
Personal Protection Equipment
HCP roles and tasks are variably impacted by personal protective equipment (PPE) (15). Although opinions vary with respect to use of respirator (N95) vs. surgical masks for neonatal resuscitation (7, 16), both may impact HCP performance. Guidelines support use of PPE in suspected or confirm COVID-19 settings, even if initial resuscitation is delayed (9). Donning PPE introduce delays when neonatal resuscitation is not anticipated, and may be done incorrectly if HCPs are rushed. When the likelihood of resuscitation is low, HCP exposure, and PPE use may be minimized by limiting the resuscitation team to 1 or 2 members. This approach acknowledges that advanced resuscitation (e.g., umbilical venous line insertion, epinephrine), if required, may be delayed. Some advocate that possible delays to emergency c-sections should be discussed with pregnant women under COVID-19 isolation (17). Similar discussions for neonatal resuscitation may be needed.
Donning and doffing PPE take practice, time, and care for full effect. When pressed for time, HCPs may don and doff incorrectly (18). Additional staff may be engaged to “spot” breaches and prevent self-contamination during doffing. PPE itself may further impact individual performance (19). The effect of masks and eye-protection on performance of neonatal resuscitation tasks is unknown. Eye-protection or fogging may hinder vision, interfering with clinical assessments and procedures such as intubation. Respirator masks create resistance to breathing and can cause anxiety and discomfort.
Finally, PPE might disrupt interpersonal communication. Face coverings can obscure both verbal and non-verbal communication. Masks can decrease speech intelligibility (20), particularly in a noisy resuscitation environment. Speech can be further distorted through devices (e.g., speaker phones) used to communicate with HCPs outside of the resuscitation room. Simulation training can help ensure safe use and familiarity with PPE, but practice with PPE can be limited by the need to conserve supplies.
In addition to PPE, HCPs experience modifications to the physical resuscitation environment. Specific labor and operating rooms may be designated for women requiring COVID-19 precautions (7). Negative pressure isolation rooms are preferred for ongoing care, if available. Not uncommonly, designated rooms are remote from the neonatal unit, not designed for isolation, and previously reserved for cases not needing neonatal equipment or team involvement. Room changes can increase travel time for the neonatal team and may delay responses due to unfamiliarity with room location and layout.
For COVID-19 cases, there are conflicting opinions on whether neonatal resuscitation should occur directly in the delivery room (DR) (7, 16). Remaining in the DR reduces the extent of contamination. On the other hand, resuscitation in a space separate from the mother (i) limits exposure of obstetrical HCPs to neonatal AGP, (ii) removes the neonate and the neonatal team from exposure to maternal infection, and (iii) allows for a dedicated resuscitation space. Some centers have rooms adjacent to DR and operating rooms for neonatal resuscitation and stabilization, ergonomically organized with equipment, and sterile supplies. These areas are infrequently designed for isolation or decontamination. Resuscitation in the DR changes the access to such organized equipment and alters workflow. Accessibility to equipment may be improved using modular, portable emergency packs that contain basic neonatal resuscitation equipment. Non-urgent interventions (e.g., line insertion), may be deferred in favor of transport to the Neonatal Intensive Care Unit (NICU) for procedures. Subsequent downstream disruptions include increased NICU workload and potential delays in procedures which would have previously occurred before transfer to the NICU. Conversely, for units used to resuscitations in the DR, resuscitating in a separate room can also be disruptive.
When transporting a potentially infected neonate to the neonatal unit, avoidance of environmental contamination and bystander exposure are priorities (21). Transporting a neonate in an enclosed incubator with a clean transport team in PPE may minimize contamination but requires additional personnel, PPE consumption, and choreographing of patient movement. Enclosed incubators are not airtight and may emit generated aerosols, contaminating hospital corridors, and putting bystanders at risk. Additional precautions include placing viral filters on ventilators to filter expired gases. The need for careful neonatal transport may (i) increase HCP workload, (ii) delay further interventions (e.g., venous access and intubation for surfactant), and (iii) increase the risk for hypothermia in small infants. Possible solutions include dedicated or escorted routes through the facility that are free of visitors and non-essential staff. Drills or briefings that clarify the physical environment, equipment, and transfer route will mitigate some of these risks.
Team Structure and Communications
Neonatal resuscitation team size and composition vary. For hospitals used to larger teams for complex resuscitations, decreasing team size to limit HCP exposure may disrupt team function. Some potential changes include: (i) team leader performing procedures such as airway management, (ii) recorder staying outside the resuscitation room, and (iii) additional HCPs and trainees waiting outside the room. During in-situ simulations, we encountered communication breakdowns between those inside and outside the resuscitation room causing inaccuracies in timing chest compressions, incomplete resuscitation records, and delays in activating additional personnel. Communication failures can further cause errors through failures in shared situational awareness and team coordination.
Neonatal, obstetrical, and anesthetic teams need to share COVID-19-related information during briefings and timeouts, and in real-time. This should help the neonatal team prepare for COVID-19 precautions, as well as minimize personnel in the operating room if a mother is being intubated and extubated. By alerting when AGP are performed, neonatal HCPs can give obstetrical team members the opportunity to take suitable precautions. These communication practices will need training and reinforcement to ensure that they occur consistently.
Finally, HCP trainees may be excluded from resuscitations of infants born to women under COVID-19 isolation. In Canada, pediatric residents report a low level of confidence in their neonatal clinical skills and may only have limited exposure to neonatal resuscitation in their training (22). If COVID-19 or other similar communicable diseases become prevalent, this approach will negatively impact our ability to train HCPs. Strategies are needed that facilitate the training of both established team members and trainees in the “new normal” of this and future pandemics.
Family and Other Impacts
Policies for increased physical distancing and isolation are highly disruptive to family-integrated care. For example, while telehealth can facilitate physical distancing for antenatal consultations, effective electronic communication can be challenging for sensitive conversations surrounding resuscitation and goals of care. Limiting family presence during active neonatal resuscitation can further impact communication, availability of emotional support, and shared decision-making. Infection control practices, such as face masks or isolation, are barriers to mother-infant interaction and bonding. Opinions on mother-infant contact post-partum differ with a balance of benefits (e.g. bonding, establishing breastfeeding, and aiding postnatal transition) against concerns for postnatal COVID-19 transmission (7, 9, 16). Involvement of parent advocates in policy development can help sustain efforts to provide safe and compassionate care during this pandemic.
Together, these potential impacts are illustrated in Figure 1.

Strategies to Examine and Minimize the Impact of Covid-19 Practice Changes on Neonatal Resuscitation
Probably the most effective path to maximizing patient and HCP safety during neonatal resuscitation is via efficiently identifying pregnant women with suspected COVID-19 prior to delivery. Over- or under-identification represent risk to the woman, the baby and/or the clinical team.
Clear rationales for practice changes as well as staff familiarity with procedure and equipment modifications will ensure that both risks and disruptions are minimized. Tabletop exercises, in-situ walkthroughs, and real-time simulations can help achieve these goals, aiding protocol development, testing, and knowledge dissemination (23). Simulations can involve just the neonatal team, or include obstetrical and anesthetic members. Local infection prevention and control (IPC) involvement ensures IPC standards are met. Frequent communication between protocol development and resuscitation teams keep frontline HCPs up to date; HCPs have identified clear communication, training, and support from managers as facilitators to following IPC guidelines (24). Ideally, frontline HCPs are involved from the planning stages to detect and mitigate impact on workflow. Continuous evaluation ensures that plans live up to the challenge of reality. At our center, teams are encouraged to provide feedback with each COVID-19 encounter. During initial stages, medical and IPC leads were notified of each COVID-19 encounter and actively solicited post-hoc feedback from frontline HCPs. Successes and challenges were shared, and protocols amended or clarified as needed. Multidisciplinary representation in our local COVID-19 response team and a dedicated neonatal resuscitation team nurse coordinator provided multiple mechanisms for HCP to provide feedback. As our frontline HCPs gained confidence and comfort in our protocols, daily in-person team huddles, and email communication facilitated ongoing feedback, communication, and support. Successful communication strategies will vary depending on unit culture, size, and acuity. Information sharing between NICUs in our region helped further refine protocols as successful strategies and solutions were rapidly disseminated.
As we learn more about perinatal transmission of COVID-19, protocols should be amended to minimize disruptions. Future redesign of neonatal resuscitation equipment, spaces, training, and teams could better address infection control and protection. Technologies such as smart glasses can provide real-time visual-audio links between team members in different rooms to help maintain team communication.
When resuscitating infants born to women with suspected or confirmed COVID-19 infection, adaptations to current guidelines are considered to protect HCPs and maintain infection control. Adaptations involve changes to ventilation procedures and equipment, use of PPE, decreasing team size, and physical distancing measures. These adaptations are assisted by early identification of maternal COVID-19 status, real-time simulations, continuous protocol evaluation, and team communication strategies. Although safety for all involved remains a priority, these changes can be disruptive and should be re-evaluated as more information emerges around the perinatal transmission of this SARS-CoV-2.
