I have written about respectful communication before in Kill them with kindness.
The importance of collaborating in a respectful manner cannot be overemphasized, as a calm and well prepared team can handle just about anything thrown their way. This past week I finally had the opportunity to take the 7th ed NRP instructor course. What struck me most about the new version of the course was not the approach to the actual resuscitation but the preparation that was emphasized before you even start! It only takes 30 seconds to establish who is doing what in a resuscitation and while it would seem logical to divide up the roles each will take on it is something that has not been consistently done (at least in our institution). When a baby is born and responds to PPV quickly, this may not seem that important but in a situation where a team is performing chest compressions, placing an emergency UVC and moving on to epinephrine administration it certainly is nice to know in advance who is doing what.
The Golden Hour
We and many other centres have adopted this approach to resuscitation and at least here developed a checklist to ensure that everyone is prepared for a high risk delivery. While teams may think they have all the bases covered, when heart rates are racing it may surprise you to see how many times crucial bits of information or planning is missed. As I told you in another post I will be releasing a series of videos that I hope others will find useful. The video in this case is of a team readying itself for the delivery of a preterm infant that they anticipate will have respiratory distress. Ask yourself as you watch the film whether your team is preparing to this degree or not. Preparing in such a fashion certainly reduces the risk of errors caused by assumptions about who is doing what or what risk factors are present.
As you can tell I am a big fan of simulation in helping to create high functioning teams! More of these videos can be accessed on my Youtube channel at

Lastly a big thank you to NS, RH and GS without whom none of this would have been possible!
We are the victims of our own success. Over the last decade, the approach to respiratory support of the newborn with respiratory distress has tiled heavily towards non-invasive support with CPAP. In our own units when we look at our year over year rates of ventilation hours they are decreasing and those for CPAP dramatically increasing. Make no mistake about it, this is a good thing. Seeming to overlap this trend is a large increase in demand by learners as we see the numbers of residents, subspecialty trainees, nurse practitioners on the rise. The combined effect is a reduction is the experience trainees can possibly hope to obtain when these rarer and rarer opportunities arise. The result of all of this is that at least by my eyes (although we haven’t documented it) the number of attempts for intubations seems to be much higher than it once was. It is not uncommon to see 3-4 attempts or sometimes more whereas in days gone by 1-2 attempts was the norm. We do our best to deal with these shortages using simulation as an example but nothing quite compares to dealing with the real thing even if it comes close.
The Less Practice You Get The More Adverse Events You Can Expect
This is just the way it is. Perfect practice makes perfect and it has been well documented that intubations can lead to many complications such as desaturation, bradycardia, bleeding, airway edema from multiple attempts and a host of other issues. Hatch and colleagues first described their experience with 162 intubations in which they found adverse events in 107 (39%) with 35% being classified as non-severe and severe events in 8.8%. Not surprisingly one of the factors associated with adverse events was the need for multiple intubation attempts. Based on this initial experience they determined that as a unit they could do better and soon after undertook a series of PDSA Quality Improvement cycles to see if they could reduce these events and that they did. What follows are the lessons learned from their QI project and it is my hope that some or all of these ideas may help others elsewhere who are experiencing similar frustrating rates.
Steps To A Better Intubation
The findings of their QI study were published last month in Pediatrics in their paper Interventions to Improve Patient Safety During Intubation in the Neonatal Intensive Care Unit. The strategies they used were threefold.
- Standardized checklist before intubation – This used a “do-confirm” approach in which the individuals on the team “do” what they need to prepare and then confirm with the group that they are done. An example might be an RRT who states “I have three sizes of ETT ready with a stylet already inserted, surfactant is thawed and the ventilator is set with settings of … if needed etc”. Another critical part of the checklist includes ensuring that everyone knows in advance their roles and who is responsible for what.
- Premedication algorithm – Prior to this project the use of premedication was inconsistent, drug selection was highly varied and muscle relaxation was almost non-existent. The team identified from the literature that a standard approach to premedication had been associated with reductions in adverse events in other centres so adopted the same here using fentanyl with atropine if preterm and muscle relaxation optional.
- Computerized order set for intubation – interestingly the order set included prompts to nursing to make sure intervention 1 and 2 were done as well.
The results of there before and after comparison were numerous but I have summarized some of the more important findings in the table below.
||Period 1 (273 intubations)
||Period 2 (236 intubations)
|<10 intubations experience
The median number of attempts were no different but the level of experience in the second epoch was less. One would expect with less experienced intubators this would predict higher risk for adverse events. What was seen though was a statistically significant reduction in many important outcomes as listed in the table. I can only speculate what the results might have been if the experience of the intubators was similar in the first and second periods but I suspect the results would have been even more impressive. The results seem even more impressive in fact when you factor in that the checklist was used despite all of the education and order set 73% of the time and muscle relaxation was hardly used at all. I believe though what can be taken out of these results is that taking the time to plan each intubation and having a standard approach so that all staff practice in the same way reaps benefits. If you already do this in your unit then congratulations but if you don’t then perhaps this may be of use to you!
What About Intubation For INSURE?
We are in the process of looking in our own centre at the utility of providing premedication when planning to give surfactant via the INSURE technique. I couldn’t help but notice that this paper also looked at that very issue. Their findings in 17 patients all of whom were provided premedication were that only one could not be extubated right after surfactant. The one who was not extubated however was kept intubated for several hours without any reasoning provided in the records so it may well be that the infant could have been electively kept ventilated when they may have indeed been ready for extubation. The lesson here though is that we likely do not need to exclude such patients from premedication it will reduce the likelihood of complications without prolonging the time receiving positive pressure ventilation.
Whatever your thoughts may be at this time one of the first questions you should ask is what is our local rate of complications? If you don’t know then do an audit and find out. Whatever the result, shouldn’t we all strive to lower that number if we can?
The giant leaps in Neonatology may for the most part be over. So many outstanding research trials have brought us to where we are today. The major innovations of surfactant replacement, the discovery of nitric oxide and its later use to treat pulmonary hypertension, caffeine for apnea have all changed our field for the better. Cooling for HIE has certainly changed my practice in that I now truly have no idea what to tell parents after even some of the worst cases of asphyxia as our team has witnessed “miracles”after cooling. What will come next? My bet is that we are about to enter the era of Quality Improvement more and more. Think about the last study you read that had a major change in your practice or better yet made a substantial change in survival or neurodevelopmental outcome.
Tweaking care is where its at.
I like to think of it as fine tuning. As the era of the major leaps in care seems to be passing us by what I see more and more are studies looking at how to make further improvements on what we already know. In some cases such as using higher doses of caffeine may reduce the incidence of apnea further compared to standard dosing while cooling for 96 hours instead of 72 and at lower temperatures after asphyxia may not be such a good idea after all. There will be some studies that suggest a modification of practice and then others that suggest we should look elsewhere for further improvements. With all of this evidence coming out in hundreds if not thousands of journals every week it is difficult to keep up and it may be that our focus is in need of a change in direction or at least devoting members of the team to look at something different.
That Focus Is On Quality Improvement (QI)
Before I go on I don’t want to insinuate that I am something that I am not. I do not have any formal training in QI and consider myself an amateur but I do understand enough to undertake a PDSA cycle and see where it takes me. To me QI is about finding ways to actually make your best practices the best they can be. Take for example our units goal to minimize needle pokes by carefully examining the usefulness of common tests that we perform. Add to this the recent implementation of non invasive technology such as transcutaneous bilirubin metres which our evidence suggests can reliably replace a serum sample to screen for those in need of phototherapy. While I commonly like to praise our team for its ability to critically think about needed bloodwork it was only through the collection of data using audit tools that we discovered we had a problem. The problem was that the rate of CBC samples that were clotting were unacceptably high at over 30%. This was compared to another NICU in the same city that had a rate of less than 1/3 that. The initial reaction since it was trained lab personnel collecting at the low clotting site vs nursing at the high rate site was that the solution was simple. Just change back to lab personnel (as it used to be) at the high rate site! Ah but that would create another problem. Other evidence used to build a care plan for our preterm infants suggested that clustering of care was better for them than poking them at the usual run time of the lab techs so we had a conflict. How did we solve it? We resisted our urge for the quick fix and entered into a formal QI project.
How did we do it and what were the results?
It took us four rounds of PDSA cycles but in the end we found a solution that has lasted. As I write this I learned that one of our two units that had the high rates set a record low this past month of a 4.9% clotting rate even lower than the comparative site that began with a low clotting rate. It took work and was by no means easy but the dedication of our nurse educator to the task made all the difference. Fortunately, for those who don’t know where to begin an incredible resource is available from BMJ Quality Improvement who provide a step by step process to carry out your project. Moreover after using their template for publishing such work, we were able to publish our work which we hope may be of help for other centres that find themselves in a similar situation. Perhaps the solution might be the same or at least similar enough to try one of our interventions? The full paper can be found at the end of the post but the trend over time is so impressive that I felt obliged to show you the results.
Why should you care?
Teams spend so much time rolling out new evidence based initiatives. All the evidence in world won’t help if the intervention isn’t achieving the results you expect. How will you know unless you audit your results? You may be surprised to find that what you expected in terms of benefit you aren’t seeing. By applying the principals of QI you may find you don’t need to look for another treatment or device but rather you simply need to change your current practice. A little education and direction may be all that is needed. You may also find to your surprise that what you thought everyone was doing is not what they are doing at all.
Resist the quick solution and put in the time to find the right solution. As Carl Honore suggests slowing things down may be the best thing for all of us and more importantly the patients we care for.
