We were able to confirm intravascular location of peripheral intravenous catheters using the color-flow injection test in pediatric patients. The test can lead to early recognition of malfunctioning peripheral intravenous catheters and decrease rate of infiltration-extravasation injuries associated with their use.

Objective. Deep tracheal extubation using dexmedetomidine is safe and provides smooth recovery in children with congenital heart disease undergoing cardiac catheterization. Design. Single-institution, retrospective study of prospectively collected data. Participants. All patients aged between 1 month and 5 years who underwent general endotracheal anesthesia for diagnostic and interventional cardiac catheterizations in the cardiac catheterization suite from January 2015 (change in standard operating procedure) through October 2016 (approval of institutional review board for study). Measurement and Main Results. One hundred and eighty-nine patients (81%) of the 232 patients who underwent cardiac catheterization during the study period were noted to undergo deep tracheal extubation. Cyanotic heart disease was present in 87 patients (46%), history of prematurity in 51 (27%), and pulmonary hypertension in 26 (14%) patients. A documented smooth recovery in the postoperative care unit (PACU) requiring no additional analgesics or sedatives was observed in 91% of the patients. The majority of patients required no airway support after deep extubation (n = 140, 74%, P = .136). The presence of pulmonary hypertension (odds ratio = 4.45, P = .035) and presence of a cough on the day of the procedure (odds ratio = 7.10, P = .03) were significantly associated with the use of oxygen or use of oral airway for greater than 20 minutes in the PACU. After extubation, there were no reported events of aspiration, the use of noninvasive positive pressure ventilation, reintubation, heart block, or systemic hypotension requiring treatment or cardiac arrest. Conclusions. Deep extubation using dexmedetomidine in infants and toddlers after cardiac catheterization is feasible and enables smooth postoperative recovery with minimal adverse effects.
