Objective To explore the effect of different sleeping state and body position nursing on the surface temperature, heart and lung function, and development of premature infants. Methods A total of 160 cases of premature infants were selected as research objects, divided into active-prone group, active-supine group, quiet-prone group, quiet-supine groupwith random number tables. Each group on the basis of conventional nursing care was given the above position. Respiratory frequency (RR), heart rate (HR), oxygen saturation (SpO2), RR deviation, HR deviation and surface temperature were observed before and after nursing. After continuous nursing for 7 days, the differences of development indexes of each group were also observed. Results Surface temperature of forehead, right flank, right forearm, right leg were (36.4 ± 0.2), (36.4 ± 0.3), (35.6 ± 0.3),(34.4 ± 0.5)℃in group C, which were significantly higher than those in the other groups (F=2.89-3.31, P<0.05). HR, RR, HR-deviation, RR-deviation and its change value in group C were (128.5 ± 1.8) beats/min, (34.6 ± 2.2) beats/min, (9.1 ± 1.2)%, (212.5 ± 31.5)%, which were significantly lower than those in the other groups (F=4.61-4.96,P < 0.05), and SpO2 change value was 0.027±0.001, which was significantly higher than those in the other groups (F=3.65,P<0.05). Weight gain, the length growth, head circumference growth and upper arm around growth in group C and A in preterm infants after 7 days of continuous nursing were (118.6±6.3) g, (11.3±1.2) mm, (6.4±0.4) mm, (4.4± 0.2) mm and (110.3 ± 5.7) g, (11.0 ± 1.1) mm, (6.0 ± 0.5) mm, (4.2 ± 0.3) mm, which were significantly better than (74.5 ± 4.4) g, (6.9 ± 0.8) mm, (4.5 ± 0.7) mm, (3.2 ± 0.2) mm of active-supine group and (78.6 ± 4.9) g, (7.6±0.7) mm, (4.8±0.6) mm, (3.5±0.3) mm of quiet-supine group (F=3.57, 4.98,P<0.05). And the above indicators of quiet-prone group were higher than that of active-prone group (P<0.05). Conclusions The quiet-prone position can improve the heart and lung function and development of premature infants.

Objective To study the therapeutic effect and significance of Naloxane on the brain function in patients with acute organ phosphorus pesticide poisoning. Methods 106 patients with acute organ phosphorus pesti-cide poisoning were randomly allocated to two groups according to the hospitalized date, the NX group(n=54) and the normal group(n=52). The two groups received the same basic treatment and the dynamic monitor about the changes of the β-EP and MDA levels in each groups, and the NX group was given additional treatment with 0.8 mg Naloxone-intravenous injection every 20 minutes till consciousness recovering or symptoms improved. Results The time of recovering consciousness was (16.71±3.17)h in NX group and (20.84±3.25)h in control group. β-EP and MDA were higher than normal before treatment in all patients (P<0.01), and were significantly reduced after treatment in NX group (P<0.05), the control group had mild change after treatment. Conclusion Relating to the inhibition of oxygen free radicals, Naloxone can reduce time of recovering consciousness and can protect the injured brain of the patients with acute organ phosphorus pesticide poisoning.
