Objective To compare the effect of high negative pressure drainage system and the traditional suction drainage system applied in thyroid surgery.Methods Eligible patients were selected randomly and divided into high negative pressure drainage group(30 cases) and traditional suction drainage group(30 cases).The draining rate within 24 hours after operation,delayed extubation rate,postoperative bleeding,rates of recurrent laryngeal nerve Injury,postoperative infection rate,degree of extubation pain and the incidence of severe pain of both groups were observed and difference of incidence of incision adhesions 1 month after operation were observed.Results The average drainage within 24 hours after operation in experimental group was (19.00 ± 6.79) ml,while (28.53 ± 14.74) ml in control group (P < 0.05).Delayed extubation rate in experimental group was 3.33 %,while 26.67% in control group (x2 =4.71,P < 0.05).Incidence of hematoma and bleeding after operation in experimental group was 0%,while 10% in control group(x2 =1.40,P > 0.05).No recurrent laryngeal nerve injury was found in either group,Incidence was 0%.The incidence of infection in experimental group was 0%,while 10% in control group (x2 =1.40,P >0.05).The incidence of severe pain when extubation in experimental group was 0%,while 100% in control group (x2 =60.00,P < 0.05).Incidence of incision adhesions in experimental group was 0.33 %,while 30% in control group (x2 =6.14,P < 0.05).Conclusion Draining rate,delayed extubation rate and incidence of incision adhesions could be reduced with high negative pressure drainage system applied in thyroid surgery,which is worthy of clinical.

Objective To study the early survival rate and its influencing factors of extremely preterm infants and extremely low birth weight ( ELBW ) infants.Method All extremely preterm infants and/or ELBW infants in Shandong Provincial Hospital from January , 2010 to December 2015 were studied retrospectively.The factors affecting their survival rate and their complications were analyzed retrospectively . All cases were assigned into the survival group and the death group .On the other hand , they were also assigned into two groups according to their birth , pre-2014 and post-2014.Result A total of 142 extremely preterm infants and/or ELBW infants were enrolled, their gestational age was 28 (27, 29) weeks, birth weight was 925 (830, 965) g.76 cases (53.5%) survived, 66 cases (46.5%) died.Factors associated with the survival rate were early onset sepsis , placental abruption , perinatal asphyxia , birth weight and pulmonary hemorrhage (P<0.05).There were 67 cases pre-2014 in which 30 cases survived (44.8%), while 75 cases post-2014 in which 46 cases survived ( 61.3%) .Comparative analysis between the two groups pre-2014 and post-2014 revealed that the survival rate was significantly different (χ2 =3.900, P=0.048).The top 2 underlying causes of death before 2014 were perinatal asphyxia and early onset sepsis . Furthermore, early onset infection became the first cause of death after 2014.Conclusion Along with the prevalence of neonatal resuscitation program and the optimization of respiratory support strategies in premature infants , the early survival rate of extremely preterm infants and /or ELBW infants has improved significantly.However, early onset sepsis may have been the crucial cause for their perinatal mortality .
