Near infrared spectroscopy monitoring during pediatric aortic coarctation repair.
Near infrared spectroscopy (NIRS) measures regional tissue oxygenation continuously and noninvasively and may allow assessment of changes in regional perfusion in real time. ⋯ Monitoring rSO2-S provides real-time trend information of regional oxygenation below the aortic cross-clamp. The decline in rSO2-S during aortic cross-clamp was rapid and large in most neonates and young infants <1 year which suggests impairment of regional perfusion presumably because of a lack of adequate collateral circulation to the monitored regional tissue. In contrast, the rSO2-S changed only to a minor degree in most infants and children >1 year, possibly because they had time to develop a more adequate collateral circulation around incomplete aortic obstruction.

Comparative StudyComparison of cuffed and uncuffed preformed oral pediatric tracheal tubes.
In preformed cuffed tracheal tubes the position of the cuff within the airway is given by its distance to the tube bend placed at the lower teeth. The aim of this study was to compare the design of cuffed and uncuffed preformed pediatric oral tracheal tubes with regard to anatomical landmarks. ⋯ There is a need for improvement in cuffed preformed pediatric tracheal tubes, namely a standard bend-to-tracheal tube tip distance to allow a safe insertion depth, a short cuff placed on the tube shaft as distally as possible and an intubation depth mark to verify a proper position of the cuff in the trachea.

Impact of a nurse practitioner-assisted preoperative assessment program on quality.
The anesthesia manpower shortage in the last few years in the US has limited many hospital pediatric surgical services. We sought to meet an increasing surgical caseload, while providing safe, timely and patient-centered care by instituting a nurse practitioner-assisted preoperative evaluation (NPAPE) program. The strategic goal of this program was to shift anesthesiologists from the preanesthesia clinic to the operating room (OR), while maintaining the quality of preoperative care. Our study sought to evaluate the quality of the NPAPE program. ⋯ Our study revealed that within a year of its implementation, the NPAPE program maintained patient safety, timeliness, and a high level of parent satisfaction as well as increased staff satisfaction, while shifting two anesthesiologists to the OR. A NP-assisted preoperative evaluation program can offer operational advantages without compromising care.

Monitored anesthesia care with a combination of ketamine and dexmedetomidine during magnetic resonance imaging in three children with trisomy 21 and obstructive sleep apnea.
We present a series of three children with trisomy 21 and obstructive sleep apnea who required sedation during magnetic resonance imaging of the upper airway. In an effort to provide effective sedation with limited effects on cardiovascular and ventilatory function, sedation was provided by a combination of ketamine and dexmedetomidine. Sedation was initiated with a bolus dose of ketamine (1 mg x kg(-1)) and dexmedetomidine (1 microg x kg(-1)) and maintained by a continuous infusion of dexmedetomidine (1 microg x kg(-1) x h(-1)). ⋯ All three patients developed some degree of hypercarbia with maximum P(E)(CO2) values of 6.4, 6.9, and 6.8 kPa (49, 53, and 52 mmHg), respectively. To date, this is the first report regarding the use of this combination in pediatric patients. Given the preliminary success noted in our three patients, prospective trials evaluating the efficacy of a dexmedetomidine-ketamine combination appears warranted.
