Data was collected on specifically designed proformas. We gathered information on the following: Unit Level designation; whether the unit used longlines and specific type used? Modality used to confirm longline tip position? Whether guide wires were routinely removed and contrast injected to determine longline position? The responders were primarily senior nurses.RESULTS We had 100% response rate. Out of the total neonatal units surveyed(170) in England and Wales, 141 units(83%) used longlines. Fifty-five out of 81 local neonatal units(68%) using longlines, used ones that came with guide wires; a similar percentage of neonatal intensive care units, i.e., 31 out of 52 units(60%) did the same. All of those units used radiography, plain X-rays, to establish longline tip position. Out of 55 local neonatal units usinglonglines with guide wires, 42(76%) were not removing wire to use contrast while this figure was 58%(18 out of 31 units) for neonatal intensive care units. Overall, only 49 out of 141 units(35%) of the units using longlines were using contrast. However it was interesting to note that use of contrast increased as one moved from special care baby units(25%, 2 out of 8 units) to local neonatal units(28%, 23 out of 81 units) and neonatal intensive care units level(46%, 24 out of 52 units) designation. CONCLUSION Neonatal units in England and Wales are overwhelmingly relying on plain radiographs to assess longline tip position immediately after insertion. Despite evidence of its usefulness, and in the absence of perhaps more accurate methods of assessing longline tip position in a reliable and consistent way, i.e., ultrasonography, contrast is only used in a third of units.展开更多

Each robot is actually a small intelligent car with seven reflective infrared photoelectric sensors ST188 installed in the front to track the line. Two rear wheels each driven by a moter are the driving wheels, while each rooter is driven by an H-bridge circuit. The running direction is con- trolled by the turning of a servo fastened to the front wheel and the adjustment of speed difference between the rear wheels. Besides, the light-adaptive line-tracking can be performed. The speeds of the motors are controlled by adjusting pulse-width modulation （PWM） values and an angular displacement transducer is used to detect the relative position of the cars in real time. Thus, the speeds of the cars can be adjusted in time so that the synchronism of the cars can be achieved. Through ex-periments, the fast and accurate synchronous tracking can be well realized.展开更多
