Forty children undergoing appendicectomy were allocated randomly to receive one of two PCA regimens with morphine. Group B10 received bolus doses of 10 micrograms kg-1 and group B20 received bolus doses of 20 micrograms kg-1. In both groups there was a lockout interval of 5 min and a background infusion of 4 micrograms kg-1 h-1. Group B20 self-administered considerably more morphine (P < 0.01) than group B10. There was no difference between the pain scores of the groups at rest. Group B20 had significantly (P < 0.05) smaller pain scores during movement than group B10 and the latter group suffered significantly (P < 0.01) more hypoxaemic episodes than group B20. There were no differences between the groups in the incidence of vomiting, excess sedation or the amount of time spent asleep at night.

Power generation with thermoelectric devices in internal combustion engines is an alternative to recover some of the energy loss with the exhausts. This data article supports a study that assesses the potentialities of energy recovery with thermoelectric generators in diesel engines and its influence on gaseous emissions. To this end, a set of experiments was developed with a thermoelectric generator and a waffle heat exchanger. The experimental design included nine operation points of the engine to characterize the energy recovery of the thermoelectric generator under different exploitation conditions. Three different fuels (i.e., diesel, B5, and B10) were used. The experiments were developed in a test bench with three data acquisition systems to measure the operational variables (e.g., electric power generation, pressure drop, temperature, etc.). Moreover, a gas analyzer (BrainBee AGS-688), Bacharach gas analyzer (PCA 400), and a smoke meter (BrainBee OPA-100) were used to measure exhaust emissions.
