| The video by Krauss et al. on
procedural sedation and analgesia in children
(April 10 issue)1 was thorough and detailed. However,
I am very concerned that 45 seconds into
the video an injection into intravenous tubing
pushes air bubbles toward the patient. The potentially
disastrous consequences of air in intravenous
lines are well known, particularly in children
with intracardiac shunts.

To the Editor: Pediatric patients have limited
respiratory reserve and are susceptible to the
rapid development of hypoxemia. The emergency
equipment mentioned by Krauss et al. does not
address the management of an unanticipated difficult
or impossible bag-mask–ventilation scenario
or the use of emergency airway devices,
including a laryngeal mask airway of the appropriate
size,1 an endotracheal tube, and a laryngoscope,
which should also be available. Furthermore,
the authors state that the administration
of supplemental oxygen before and during sedation
renders pulse oximetry ineffective with regard
to early warnings of respiratory depression and
recommend the use of capnography when supplemental
oxygen is used. These aspects of the
video could lead to the misconception that the observation
of ineffective pulse oximetry in the
early detection of hypoventilation is related to
the administration of supplemental oxygen or
that capnography cannot be used if supplemental
oxygen is not used simultaneously |
