Keeping children with respiratory distress relaxed and quiet is the safest and ideal way to manage them. Agitation, screaming and crying may worsen airway swelling and/or bronchospasm. Additionally, a struggling child requires increased oxygen consumption, which should be avoided. Using individuals whom the child is comfortable with is often an easy solution. All pediatric patients with signs of potential respiratory dysfunction should receive supplemental oxygen.

Critically ill or unstable patients receiving ventilatory support should be transferred to an intensive care setting where the staff is trained and capable of managing this higher level patient. All patients receiving positive airway pressure are at risk for life-threatening events like the development of a tension pneumothorax. The staff needs to be able to rapidly diagnose and treat this problem to prevent a bad outcome for the patient.

Manufacturers supply pediatric chest patches that better fit the smaller chest. In an extreme emergency, if only larger adult patches are available, place the patch in an anterior/posterior* position, making certain there is no contact between the two electrodes.

*Place one patch on the front of the chest, over the heart, left of the sternum if possible. Place the second patch at the cardiac level on the rear chest.

CPR is essential in pulseless patients regardless of their ECG rhythm. If there is no need to defibrillate, epinephrine is recommended. The stark reality is that if the cause of the arrest is not identified and treated very quickly, death is ruled. During the resuscitation, attempts  should be made to identify medical futility. If it exists, resuscitation attempts should cease.

Because adenosine stops conduction through the AV node for several seconds, it often converts tachyarrhythmias whose circuitry bisects with the AV node (i.e., AV nodal reentrant tachycardia, etc.). Certain SVT’s have wide QRS complexes, and if the R-R interval is regular, adenosine can be administered as long as the patient is stable. Sinus tachycardia is not an arrhythmia per se, but a response to things such as anxiety, pain, hypovolemia, and fever. Patients with sinus tachycardia need the underlying causes treated. Adenosine will not be of benefit and should not be given.
