ABSTRACT
Objective To evaluate the occurrence and risk factors for healthcare-associated infection(HAI)in pre-mature infants.Methods The occurrence of HAI among premature infants who were born in a hospital from Janu-ary 2011 to June 2015 and admitted in the neonatal intensive care unit within 24 of birth were investigated prospec-tively,the related risk factors and intervention measures were analyzed.Results 644 premature infants were inves-tigated,32(4.97%)had HAI,the main infection site was lower respiratory tract (n=18,56.25%).34 pathogenic isolates causing HAI were detected, 24 (70.59%) were gram-negative bacteria, the major was Klebsiella pneumoniae (n=14);10 isolates were gram-positive bacteria(29.41%).Logistic regression analysis revealed that small for gestational age, low birth weight, severe amniotic fluid pollution, mechanical ventilation, feeding intolerance,indwelling gastric tube,irrational antimicrobial use,and long length of hospital stay were risk factors for HAI in premature infants (all P < 0.05).Conclusion Risk factors for HAI in premature infants are multiple, targeted interventions,such as shorten the length of hospital stay,reduce unnecessary invasive operation,use antimicrobial rationally,improve the feeding tolerance,are helpful for reducing the risk factors for HAI in premature infants.
ABSTRACT
Objective To evaluate the effects of perioperative rehabilitation for patients with self-forearm internal arteriovenous fistula.Methods Divided 124 patients with end-stage renal disease into the functional training group (65 cases,A group)and the control group(59 cases,B group) randomly,and then compared certain related indexes between the two groups.Results In the A group,the artery diametcr was obvious widen before functional training without operation,and the vein diameter was obvious widen before functional training without operation too,P ＜ 0.05.After operation,the A group Anastomotic unobstructed was obviously better than B group in one-stage,P ＜ 0.05.A group with thrombosis cases significantly less postoperative than B group,P ＜ 0.05.A group with edema of hands was significantly shorter than B group,P ＜ 0.01.Postoperative fistula time to maturity in the A group was (43.76 ± 2.21) days,which was significantly shorter than that of in the B group,(49.69 ± 5.85) days,P ＜ 0.01.Conclusion Systematic strengthening of perioperative functional exercises can significantly improve preoperative vascular conditions,improve the success rate of operation,reduce risk of thrombosis cases,shorten the time of hand edema and the time of fistula in mature.
