ABSTRACT
Objective To investigate the efficacy and application of bronchoalveolar lavage in chil-dren with severe pneumonia undergoing mechanical ventilation. Methods Using a prospective randomized controlled clinical study, 202 children with severe pneumonia received mechanical ventilation in Hunan Children′s Hospital from January 2016 to January 2018 were selected as the subjects. According to the digital method,all cases were divided into treatment group (101 cases) and control group (101 cases) randomly. The patients in the control group were given conventional treatment ( anti-infection and symptomatic thera-py) . The treatment group was treated with bronchoalveolar lavage on the basis of conventional treatment. The basic situation,the respiratory function before and after the treatment,the inflammation index,the curative effect and the prognosis of two groups were analyzed. Results There were no significant differences between the two groups in gender,age,course pre-admission,pediatric critical illness score,respiratory function and in-flammation index ( P>0. 05 ) . The respiratory function indexes of the treatment group were obviously im-proved 2 hours after the treatment and the PaO2 ,PaO2/FiO2 and SaO2 were significantly higher than those of the control group[PaO2(82. 4 ± 6. 4) mmHg(1 mmHg=0. 133 kPa) vs. (74. 0 ± 5. 5) mmHg, PaO2/FiO2(360. 2 ± 21. 3) mmHg vs. (332. 6 ± 23. 5) mmHg,SaO2(94. 9 ± 8. 2)% vs. (88. 6 ± 10. 3)%], while the PaCO2 were significantly lower than the control group [ ( 37. 3 ± 10. 3 ) mmHg vs. ( 45. 8 ± 5. 5 ) mmHg],and the differences were statistically significant (P<0. 05). Five days after treatment,the WBC, PCT and CRP of treatment group were significantly lower than those in the control group[WBC(8. 5 ± 2. 4) × 109/L vs. (11. 7 ± 3. 5) × 109/L,PCT(1. 2 ± 0. 7) μg/L vs. (2. 3 ± 0. 9) μg/L,CRP(9. 1 ± 3. 2) mg/L vs. (16. 5 ± 4. 7) mg/L,P<0. 05,respectively]. The total effective rate in the treatment group was significantly higher than that in the control group[93. 1%(94/101)vs. 81. 2%(82/101)]. Mechanical venti-lation duration and PICU stay in treatment group were significantly shorter than those in the control group [(148. 5 ±30. 6)h vs. (159. 6 ±47. 3)h,(220. 8 ±49. 7)h vs. (330. 7 ±94. 6)h]. The positive rate of patho-genic bacteria was significantly higher than that in the control group [79. 2%(80/101)vs. 62. 4%(63/101), P<0. 05],but there was no significant difference in the 28 days mortality of the two groups[5. 0%(5/101) vs. 5. 9%(6/101),P>0. 05]. Conclusion The bronchoalveolar lavage can improve the respiratory func-tion,reduce the inflammatory reaction,shorten mechanical ventilation duration and PICU stay in children with severe pneumonia undergoing mechanical ventilation obviously. It is worth popularizing in the PICU because of the improvement of curative effect in these children.
