目的 分析不同降温方式在发热患儿体温管理中应用效果.方法 纳入2021年1月至2021年12月在本院儿科住院的发热患儿400例作为研究对象.随机将患儿分为药物降温组和混合降温组,每组200例.药物降温组采用口服药物布洛芬混悬液进行治疗,混合降温组采用布洛芬混悬液加温水擦浴组进行治疗.分析对比两组的降温幅度,疼痛情况和不良反应.结果 混合降温组在T1-T0、T2-T1、T3-T2时间点降温幅度均明显大于药物降温组(P<0.05).两组降温前后VAS评分无明显差异(P>0.05).混合降温组不良反应发生率比单纯药物降温组均较高,两组对比有明显差异(P<0.05).结论 发热患儿体温管理采取布洛芬混悬液联合温水擦浴组效果更明显,能提高降温幅度,缓解疼痛,但降温过程中产生不良反应较多,应根据患儿病情及家属意愿选择.  相似文献

目的探讨药物治疗早产儿动脉导管未闭(PDA)的时机。 方法回顾性分析2016年1月至2018年12月四川锦欣妇女儿童医院新生儿科收治的符合入选标准的早产儿(胎龄<32周)151例。根据布洛芬的使用情况分成3组,其中症状时治疗组43例、症状前治疗组32例、对照组76例。根据是否诊断为有血流动力学意义的PDA(hsPDA),分为hsPDA组和非hsPDA组,症状时治疗组属于hsPDA组,症状前治疗组及对照组属于非hsPDA组。出生第1天检测血常规、生化、血气分析等。出生满3 d筛查超声心动图,记录当日脉压差及尿量。两治疗组,口服布洛芬10 mg/kg,24 h及48 h后各予5 mg/kg,治疗72 h后复查超声心动图。对照组,未予布洛芬治疗,出生后7 d复查超声心动图。复查PDA患儿,出生后30 d再次复查超声心动图。采用χ2检验比较症状时治疗组、症状前治疗组、对照组3组间性别、孕母使用过激素的比例、胎膜早破>18 h比例、剖宫产比例、小于胎龄儿比例、动脉导管7 d关闭率、动脉导管30 d关闭率、脓毒症发生率及呼吸窘迫综合征、脑室内出血、支气管肺发育不良、坏死性小肠结肠炎发生率等的差异;采用单因素方差分析比较胎龄、出生体质量、尿量、脉压差、血pH值的差异;采用Kruskal-Wallis H法比较5 min Apgar评分、正压通气时间、吸氧时间等的差异。 结果性别、胎龄、孕母使用过激素、胎膜早破、剖宫产、出生体质量、小于胎龄儿,5 min Apgar评分、血pH值、尿量、呼吸窘迫综合征发生率,动脉导管生后30 d关闭率、正压通气时间、吸氧时间,发生脑室内出血、支气管肺发育不良、坏死性小肠结肠炎情况,在症状时治疗组、症状前治疗组、对照组3组之间比较,差异均无统计学意义(P>0.05)。症状前治疗组、症状时治疗组和对照组3组间脉压差分别为(22.13±13.83)mmHg(1 mmHg=0.133 kPa)、(24.24±9.72)mmHg、(16.22±8.81)mmHg,症状前治疗组高于对照组,差异无统计学意义(t=0.732、P=0.639),症状时治疗组高于症状前治疗组和对照组,差异均具有统计学意义(t=3.25、4.710,P=0.002、<0.001)。3组脓毒症发生率分别为9.38%(3/32)、27.91%(12/43)和10.53%(8/76),症状前治疗组低于对照组,差异无统计学意义(χ2=0.033,P=0.856);症状时治疗组高于症状前治疗组和对照组,差异均具有统计学意义(χ2=5.933、4.230,P=0.015、0.040)。动脉导管生后7 d关闭率,症状时治疗组和症状前治疗组均高于对照组[65.63%(21/32)vs 60.47%(26/43)vs 32.89%(25/76)],差异均具有统计学意义(χ2=8.524、9.866,P=0.004、0.002)。动脉导管生后30 d关闭率组间差异均无统计学意义(P>0.05)。 结论口服布洛芬可以促进动脉导管早期闭合,但对远期闭合率并无明显优势。预防性布洛芬干预不能缩短PDA早产儿的正压通气、吸氧时间及降低脑室内出血、支气管肺发育不良、坏死性小肠结肠炎等并发症的发生率。而对hsPDA,布洛芬干预能否减少呼吸支持依赖及并发症的发生仍有待于进一步的研究。  相似文献

The objective of this work was to study the relation between the manufacturing conditions of microcrystalline cellulose (MCC), its physicochemical properties and its tableting behavior. Two different preparation procedures were used to produce MCC from wheat straw, utilizing an acid hydrolysis method, either using only sulfuric acid or combination of sulfuric and hydrochloric acid. The tableting behavior of obtained MCC samples and mixtures of MCC with ibuprofen was studied using a dynamic powder compaction analyzer. It was observed that some of the obtained MCC samples showed better flowing properties than commercially available Vivapur® PH101 and also very high values of tensile strength, solid fraction and elastic recovery. This can be linked with its good compaction behavior, but on the other hand it can cause problems with the disintegration of the tablets. In mixtures with ibuprofen, MCC samples showed lower values of tensile strength, while on the other hand elastic recovery did not seem to be much affected, still exhibiting very high values. According to the obtained results, it can be concluded that MCC obtained from the agricultural waste could have satisfactory properties for tablet preparation by the direct compression method. Further studies are needed to optimize process conditions in order to achieve better physicochemical characteristics, especially in terms of elastic recovery.  相似文献

Despite the Cox inhibitory anti-inflammatory and antipyretic effects of most widely used non-steroidal anti-inflammatory drugs (NSAIDs), such as Ibuprofen, their chronic use is associated with a plethora of patho-physiological insults. One such toxic effect on testicular tissues is not well studied and the underlying molecular mechanisms remain unexplored. Thus, the current study is designed to evaluate the antioxidant properties of essential trace element selenium (Se) to ameliorative Ibuprofen associated testicular toxic effects. Adult male Wistar rats were divided into 3 groups and fed on diets containing different concentrations of sodium selenite, viz. 0.01 mg/kg (Se- deficient), 0.2 mg/kg (Se-adequate), or 0.5 mg/kg (Se- supplemented) for 8 weeks. After diet feeding schedule, each group was divided into two subgroups i.e., with or without the treatment of Ibuprofen (120 mg/kg Bw). The protective effect of Se was evaluated by measuring testicular Se and selenoproteins status, spermatogenic markers, histopathology and testicular redox status. Ibuprofen diminished seminal volume, sperm count, sperm motility, which correlated well increased testicular reactive oxygen species. Se deficiency exacerbated these detrimental effects of ibuprofen by increasing oxidative stress. Alternatively, Se supplementation through antioxidant enzymes mediated protective effects. Se as essential antioxidant selenoproteins ameliorates Ibuprofen induced male reproductive toxicity.  相似文献

IntroductionPatent ductus arteriosus (PDA) in preterm infants has been associated with increased mortality and comorbidities. This study aimed to characterize the population of preterm infants diagnosed with PDA and to identify predictive factors of response to medical treatment of PDA.MethodsAn eight-year retrospective observational study was carried out, which included all preterm infants with a gestational age (GA) between 23 and 32 weeks diagnosed with PDA, admitted to the Neonatal Unit of the CHUSJ. Univariate comparative analysis was performed, and models for predicting the effectiveness of PDA treatment with ibuprofen were explored by multivariate logistic regression analysis.Results115 cases were included and 34 were excluded, with a final sample of 81 preterm infants with PDA. The univariate analysis revealed significant differences in the closure efficacy via medical treatment with ibuprofen in several variables, and a multivariate logistic regression model was obtained (discriminative capacity 72.2%, sensitivity 98.1%, specificity 57.1%), taking into account the effect of GA, type of delivery, need for diuretics treatment and platelet transfusion.ConclusionThis study enabled the population of preterm infants diagnosed with PDA to be characterized and the identification of a predictive model that can help predict the efficacy of medical treatment and thus contribute to optimizing the medical approach to the non-responders.  相似文献

Abstract

The objective of the present study was to investigate the influence of processing methods on the physical and mechanical properties of formulations containing Ibuprofen and HPC-SSL. The powder blends, containing Ibuprofen and HPC-SSL in ratio of 9:0.5, were processed using melt granulation (MG) by hot melt extrusion (HME) and wet granulation (WG) by high shear mixer. Formulated granules and powder blends were compressed into round flat faced tablets using Riva Piccola tablet press. Differential scanning calorimetry (DSC) and X-ray powder diffraction (XRPD) studies proved that granulation process did not significantly alter the crystallinity of Ibuprofen, however, particle density and flow properties were significantly improved. Scanning electron microscopy (SEM) and particle size analysis corroborate with the findings that the flow characteristics of granules from MG were relatively superior to other formulations. Formulations were investigated for out-of-die compaction behaviour using Heckel, Kawakita, and CTC profile analysis. Detailed examination revealed that all three formulations differed in particle size due to the granulation, thus conferring to different compaction behaviour. In WG and MG, granulation offered an increase in particle size resulting in high compressibility along with deformation at low compression pressure. This results into low yield pressure, low yield strength, and higher densification, as compared with dry blend. The current work provides an insight into factors affecting physical and mechanical properties tablets, which can facilitate the rational selection of suitable change in processing method instead of changing excipients.  相似文献
