Objective:To evaluate the analgesic effect of low dose ropivacaine combined with fentanyl in patient controlled epidural analgesia (PCEA) and its influence on labor and safety of mothers and their newborns. Methods:One hundred and forty healthy nullipara at term were randomly assigned to epidural analgesia or control group. The analgesia group received PCEA when their labor stage reached active period in the first stage of labor.The PCEA mode was background infusion 6 ml/h, bonus 2 ml,lockout time 10 min/each infusion. The VAS, modified Bromage scale(MBS),duration and mode of labor, postpartum hemorrhage,Apgar scores of newborns were recorded. Results:Fifteen minutes after application of PCEA,98.58% of patients felt no pains(VAS 0.057?0.48),only 4.8% showed a mild motor block(MAS 0.07?0.31).By the 60 min,all patients could move the lower limbs freely (MAS 0). The analgesia group had a significantly shorter duration of active period in the first stage of labor than that of the control group, but a significant longer duration of the second stage. In addition, the oxytocin usage was significantly more frequently in analgesia group than those in placebo group.There was no difference between the two groups in the duration of third stage, postpartum hemorrhage, Apgar scores of newborns in 1 min and 5 min, rate of cesarean section and instrumental delivery.Conclusion:Epidural analgesia with low dose ropvicaine combined with fentanyl is safe and effective, which has no influence on mothers and their infants. It could shorten the active period of labor, but may increase oxytocin usage. The ratio of cesarean section and instrumental delivery was similar between the two groups. This kind of labor analgesia is beneficial and do no harm to mothers as well as newborns.

Objective To study the clinical features of invasive pneumococcus disease (IPD) with resistance to antimicrobial agents in children,and to improve the diagnosis and treatment of this disease.Methods The clinical data from 21 IPD patients younger than 13 years old were collected from January 2008 through December 2010 in Pediatric Intensive Care Unit in Beijing Children's Hospital for retrospective analysis. Specimens of blood,pleural effusion,cerebrospinal fluid and soft tissue aspirated were collected from these children,and 23 strains of streptococcus pneumonia (SP) were cultured,isolated and confirmed,and the antibiotics susceptibility to penicillin and other antibiotics of these strains were assayed.Results Among the 21 IPD children,the ratio of male to female was 0.9∶1,and the age was 5 months to 13 years,with 61.9％ of them under 2 years.Of them,12 patients (57.1％ ) had purulent pleurisy,and 1 (4.8％ )patient had an underlying disease diagnosed to be X - linked agammaglobulinemia (XLA).There was no seasonal difference in the occurrence rate of this disease. Eight (38.1％) patients were cured,11(52.4％ ) were improved,while 2 (9.5％ ) patients not improved without death.There was no statistically significant difference in the annual detection rate of invasive SP (x2 =3.711,P =0.156).The incidences of penicillin-intermediate susceptibility SP (PISP) and penicillin-resistant SP (PRSP) were 47.8％ and 26.1％ respectively.The rate of resistance to multiple antibiotics was 91.3％.Conclusions Children aged less than 5 years,especially younger than 2 years,are prone to IPD,and purulent pleurisy and septicemia are often seen in this disease. Some patients had the underlying diseases.The complications included hemophagocytic syndrome,acute respiratory distress syndrome,septic shock,bronchial pleural fistula and so on.The multidrug resistance rate was 91.3％.It is important to put great emphasis on the monitoring antibiotics resistance to invasive pneumococcal disease.

Objective To investigate the prevalence of vitamin D deficiency and to examine its relationship with the severity and prognosis in the critically ill children. Methods A total of 83 critically ill children admitted from November 1,2010 to December 9,2010 to Pediatric Intensive Care Unit in Beijing Children's Hospital,Capital Medical University were enrolled in the study. Serum 1,25 - Dihydroxyvitamin D concentration was measured by using an en-zyme - linked immunosorbent assay(ELISA). Anthropometric parameters such as height/ length and weight of the chil-dren were measured. Data collection also included primary disease,Pediatric Critical Illness Score(PCIS),the Pediatric Risk of Mortality Ⅲ(PRISM Ⅲ)score,multiple organ dysfunction syndrome( MODS)rate,mechanical ventilation rate,time of hospital of stay and the 28 - day survival rate. Results There were 32 cases with vitamin D deficiency on admission,vitamin D deficiency rate on admission was 38. 6% ,and there was no statistically significant difference among different primary disease groups(P = 0. 815). Vitamin D deficiency rate of malnutrition group was lower than that of the normal group[60. 0%(12 / 20 cases)vs 40. 0%(8 / 20 cases),χ2 = 5. 989,P = 0. 014]. PCIS scores of those with a normal vitamin D status was higher than those of the vitamin D deficiency group,showing a significant difference [(80. 47 ± 6. 18)scores vs(77. 16 ± 7. 59)scores,P = 0. 022]. PCIS score was positively correlated with the vitamin D level(r = 0. 267,P = 0. 015). There was no statistically significant difference among the PRISM score,MODS rate, mechanical ventilation rate,hospital stay length and the 28th day survival rate between the normal vitamin D group and the vitamin D deficiency group(all P ﹥ 0. 05). Conclusions A high prevalence of vitamin D deficiency is found in the critically ill children. The prevalence of vitamin D deficiency in children with malnutrition is higher. Vitamin D status may be correlated to the severity of the critically ill children,but the association with the prognosis is not obvious.

Objective To investigate the effects of airway pressure release ventilation (APRV) in children with severe pneumonia-related acute respiratory distress syndrome(ARDS).Methods Ten children suffering severe pneumonia-related ARDS with APRV were included in Pediatric Intensive Care Unit, Beijing Children's Hospital,Capital Medical University from March 2011 to October 2014.Ventilation variables, changes of airway pressure and Ramsay scores were collected and compared with that in conventional ventilation (CV).Clinical variables were measured at CV before APRV and at 1,4,12,24 hours after transition to APRV.Results High airway pressure(Phigh) at each time point during APRV was significantly lower than peak airway pressure (Ppeak) or plateau airway pressure (Pplat) in CV[(26.00 ±2.94) cmH2O(1 cmH2O =0.098 kPa) ,(24.40 ±3.34) cmH2O,(23.30 ±3.46) cmH2O,(23.00 ± 3.80) cmH2O vs (31.80 ± 5.59) cmH2O, P ＜ 0.01].Mean airway pressure (Pmean) at each time point during APRV was significantly higher than that in CV [(23.00 ± 2.86) cmH2 O, (21.69 ± 3.12) cmH2 O, (20.89 ± 3.31) cmH2 O, (20.46 ± 3.48) cmH2 O vs (17.50 ± 2.37) cmH2 O, P ＜ 0.05].Fraction of inspired oxygen (FiO2) were significantly decreased at 4, 12 and 24 hours after APRV than that in CV [(73.00 ± 22.39) ％, (63.50 ± 20.16) ％, (63.00 ± 21.11) ％ vs (88.00 ± 15.49) ％, P ＜ 0.05].Ramsay scores were significantly decreased at each time point during after APRV than that in CV [(3.90 ± 0.74) scores, (2.90 ± 0.88) scores, (3.00 ± 1.15) scores,(3.50 ± 0.71) scores vs (4.60 ± 0.52) scores, P ＜ 0.05].Conclusions Compared with CV, APRV had a lower Phigh and FiO2 ,a higher Pmean and more shallow sedation.APRV may be an effective ventilation mode in children's severe pneumonia-related ARDS.
