Changes in pCO2 during air medical transport of children with closed head injuries.
OBJECTIVES: Because low partial pressure of carbon dioxide (pCO2) can be associated with posttraumatic cerebral ischemia, we conducted a study to determine whether the pCO2 level in ventilated children with closed head injuries transported by a trained team to tertiary care was optimally maintained during transport and determine whether hand-bagging or mechanical ventilation resulted in more optimal pCO2 levels after transport. METHODS: We reviewed the hospital charts and transport records of all infants and children who had sustained a head injury and were transported by a specialized pediatric transport paramedic team to a single tertiary care facility during a 12-month period. All children were intubated and ventilated either mechanically or manually. Outcome measures were final pCO2 before transport and first pCO2 on arrival in the PICU. RESULTS: Twenty-nine children (age 0.6 to 16 years, mean 7.3, median 6) met the criteria. Fourteen patients were hand-bagged (HB), and 15 were mechanically ventilated (MV). Eleven patients (5 HB and 6 MV) started in the target pCO2 range of 35 to 40 mmHg. After transport, nine patients (all MV) had pCO2 within the target range (P < 0.01). Duration of transport (mean 63 minutes, range 15-200 minutes) did not contribute to the final pCO2 level. CONCLUSION: MV improves management of pCO2 during interfacility transport. HB significantly increases the incidence of suboptimal pCO2 and hence the risk of suboptimal cerebral blood flow. MV appears mandatory, and monitoring CO2 in transit (end-tidal or preferably point-of-care testing) should further reduce the likelihood of secondary complications from cerebral ischemia.

NCTR computer systems designed for toxicologic experimentation. IV. Experiment information system.
The Experiment Information System (EIS) is a computerized data collection, maintenance, and reporting system for specified information values collected during the lifespan of animals assigned to toxicologic investigations at NCTR. The system records and/or controls experimental variables, which might ultimately affect the results, through the operation and integration of the Diet Preparation Subsystem (DPS), the Environmental Monitoring Subsystem (EMS), the Microbiology Subsystem (MBS), and the Chemistry Data Subsystem (CDS). The fifth component of the EIS, the Experimental Data Collection Subsystem (EDCS), is responsible for handling all data generated by, or attributed to, the animals from assignment until death or removal. Through integration of these five subsystems, the history of an animal while on study is recorded and stored for later recall. In addition, "routine" and "special" reports are made available through the system software which enables stringent control of the experiment by the Principal Investigator, Animal Husbandry, and NCTR Management.
