ABSTRACT
Objective To explore the characteristics of thrombelastogaphy( TEG)in term neonates,and to evaluate their correlation with traditional coagulation tests. Methods A total of 52 term neonates were enrolled as neo-natal group and 34 adults undergoing elective surgery as adult control group in Jiangmen Central Hospital from January to December 2017. TEG,plasma coagulation test and platelet counts(PLT)were performed and the corresponding ana-lysis was conducted. Results TEG parameters in term neonates:response time(R)(4. 18 ± 1. 08)min,clot kinetics (K)(1. 21 ± 0. 45)min,α angle( Angle)(73. 08 ± 5. 74)°,maximum amplitude( MA)(65. 68 ± 7. 13)mm. Com-pared with adult control group,neonatal group exhibited shorter R and K(t=3. 764,P<0. 001;t=4. 888,P<0. 001), higher Angle,MA(t=5. 539,P<0. 001;t=2. 873,P=0. 001). In traditional coagulation,compared with adult control group,neonatal group showed longer prothrombin time( PT),activated partial thromboplastin time( APTT),thrombin time(TT)(t=5. 449,P<0. 001;t=13. 134,P<0. 001;t=3. 575,P=0. 001),lower fibrinogen( Fib)(t=4. 164, P<0. 001),and higher PLT(t=4. 230,P<0. 001). In addition,K was negatively correlated with Fib(r= -0. 374, P=0. 004),while Angle and MA were positively correlated with Fib(r=0. 354,P=0. 007;r=0. 630,P<0. 001);K was negatively correlated with PLT(r= -0. 430,P=0. 001),but Angle and MA were positively correlated with PLT (r=0. 427,P=0. 001;r=0. 586,P<0. 001);K was positively correlated with APTT(r=0. 285,P=0. 035),and MA was negatively correlated with APTT(r= -0. 324,P=0. 017). There was no significant correlation between R and tra-ditional coagulation test. K,MA and Angle were not significantly correlated with PT(all P >0. 05),and Angle and APTT were not significantly correlated(all P>0. 05). Conclusions The reference interval of TEG in term neonates is different from adults. And the parameters of TEG in term neonates are partly related to the traditional coagulation tests.
ABSTRACT
Objective To explore the preventive effect of Fluconazole on invasive fungous infections in premature infants.Methods Two hundred and thirty-four cases of preterm infants hospitalized in Jiangmen Central Hospital from Feb.2008 to Oct.2013 were analyzed by retrospective study.The subjects were divided into 3 groups based on whether Fluconazole was used and it was used orally or intravenously for the prevention of invasive fungous infections in premature infants.The Fluconazole prophylaxis was not given to group A,whereas oral Fluconazole prophylaxis [6 mg/(kg · times),every other day] and intravenous Fluconazole prophylaxis [3 mg/ (kg · times),once every 3 days] were applied in group B and group C.The incidence of invasive fungous infections and the clinical effects of Fluconazole on the 3 groups were evaluated and compared.Results The number of cases analyzed in the study were 53,115 and 66 cases in group A,group B and group C,respectively.There were no significant differences between the 3 groups in terms of gender,gestational age,birth weights,length of hospitalization,intravenous nutrition,and number of peripherally inserted central catheter,antibiotics and invasive mechanical ventilation use days (all P ＞ 0.05).The incidences of invasive fungal infections were 11.32％ (6/53 cases),6.96％ (8/115 cases) and 0 in group A,group B and group C,respectively.The prophylaxis effects between the 3 groups were significantly different (x2 =7.078,P =0.029).Group A and group B were not significantly different (x2 =0.905,P =0.342),but group C was better than group A and group B,and the differences were significant (P =0.007,0.028).Conclusions Prevention of invasive fungous infections by intravenous Fluconazole has good curative effects,and which can be used as the first choice.
