VIDEOKIDS Trials a Head-to-Head Airway Strategy in Paediatric Surgery

Tracheal intubation is one of the most consequential moments in paediatric anaesthesia. A misplaced tube or a prolonged attempt can quickly turn a routine procedure into a crisis, especially in smaller children where airway reserve is limited and desaturation can arrive fast. The VIDEOKIDS study protocol sets out to test whether videolaryngoscopy can improve intubation outcomes over direct laryngoscopy in a large pragmatic cohort of children undergoing surgery.

The trial is designed as a prospective, international, multicentre, open-label, randomised controlled study involving approximately 5,600 paediatric patients. Children from birth to 16 years will be enrolled, with randomisation stratified by centre and by three prespecified age groups spanning 1 to 16 years. The age range matters because airway anatomy, cooperation, and procedural difficulty shift markedly across childhood, and a single strategy rarely performs identically in neonates, infants, school-age children, and adolescents.

First-attempt success sits at the centre of the question.

In airway management, the first pass is more than a convenience metric. Every additional attempt exposes the child to repeated laryngeal stimulation, longer apnoea time, and a greater chance of hypoxaemia or airway trauma. A device that improves visualisation should, in theory, increase the likelihood of rapid tube placement, but the bedside value of that advantage depends on the setting, the clinician’s experience, and the range of patients actually encountered in real-world surgery. This is why a large pragmatic trial is clinically relevant: it is built to test performance across routine care rather than under narrow, idealised conditions.

A Pragmatic Design Across Diverse Healthcare Systems

The planned trial will run in roughly 20 to 25 hospitals across six countries with different healthcare systems and levels of healthcare expenditure. That international spread is not a cosmetic detail. It builds variability into the sample, including differences in operating room workflow, local airway practice, equipment access, and training background. The protocol also anticipates clinicians with varying levels of experience, which is crucial for interpreting whether videolaryngoscopy offers a durable advantage or whether its benefit depends on who holds the device.

Because this is an open-label study, clinicians cannot be blinded to the allocated technique. That limitation is built into the nature of airway procedures: the person performing the intubation necessarily knows whether a video screen or a direct line of sight is being used. Even so, randomisation at the patient level and stratification by centre and age group should help balance the comparison across sites and reduce the chance that one group inherits a systematically easier airway mix.

The protocol’s scale is notable in itself. A paediatric airway trial with 5,600 participants is large enough to examine performance across a broad clinical spectrum, including younger children who are often the most vulnerable to oxygen desaturation. In that sense, the study is not only about equipment choice. It is about whether a shift in visualisation technology changes the mechanics of a time-critical procedure across a wide and heterogeneous surgical population.

Why First-Pass Success Matters More in Children

Paediatric tracheal intubation has a different risk profile from adult airway management. The margin for error narrows as patient size decreases, and airway anatomy can make tube passage more demanding even when the glottic view appears adequate. A better view does not automatically translate into easier tube delivery, and that distinction is one of the reasons the trial protocol is important. Videolaryngoscopy may improve visual access to the larynx, but the real test is whether that visual gain produces meaningful bedside efficiency in the hands of clinicians working across different institutions.

The protocol is anchored in that practical question. If videolaryngoscopy increases first-attempt success, the effect could reduce repeated instrumentation, shorten apnoea intervals, and lower the chance of airway complications during surgery. If the devices perform similarly, then direct laryngoscopy remains a robust standard and the added cost and complexity of widespread video use would need to be justified on other grounds. Either outcome would carry weight for paediatric anaesthesia teams.

A single failed pass can alter the whole case.

That is particularly true in a child with limited physiological reserve, where the difference between rapid tracheal access and repeated attempts can translate into a very different intraoperative course. Even without reporting outcomes, the protocol identifies the central clinical pressure point: the first attempt is the one most likely to determine whether the procedure proceeds smoothly or becomes progressively more difficult.

What the Trial Is Built to Measure

The protocol positions videolaryngoscopy and direct laryngoscopy as competing approaches to the same core procedural goal: safe and effective tracheal intubation in children undergoing surgery. The prespecified age strata signal an intention to examine whether the intervention performs consistently across developmental stages rather than averaging away important differences between infants and older children. Stratification by centre also suggests awareness that local practice patterns can strongly influence airway outcomes.

Because the trial is pragmatic, it is designed to reflect routine clinical care rather than an artificially controlled environment. That choice should make the findings more relevant to daily anaesthesia practice, where the relevant question is not only whether a device can work, but whether it does work under ordinary conditions in ordinary hands.

The open-label nature of the study will leave some interpretive challenges, particularly for outcomes that may be influenced by operator judgement. Still, the randomised design and multicentre scope provide a strong framework for comparing the two techniques in a setting that resembles actual paediatric surgical care. This is especially important in airway research, where small single-centre studies can be skewed by a narrow case mix or by the skills of a particularly experienced group of operators.

Why This Protocol Matters Before the Results Arrive

As written, the protocol addresses a question that sits close to the front line of paediatric anaesthesia: does improved visualisation through a video device translate into better intubation performance in children? The answer will matter most if it is consistent across ages, centres, and healthcare systems, because those are the settings in which a technique must prove itself before it can be adopted broadly.

The study’s most meaningful limitation is already visible in the design. Blinding is not possible, so operator awareness will remain part of the trial environment. Even so, the large sample size, the international structure, and the full paediatric age range give the study enough breadth to inform practice in a way that smaller airway trials cannot.

The results will determine whether videolaryngoscopy becomes a stronger default strategy for paediatric intubation or remains one option among several, depending on local expertise and patient factors. Until those data arrive, the protocol itself makes one thing plain: airway management in children is still an area where better technology must prove itself against the demands of real-world surgery, not against idealised conditions in a simulation room.
