Chinese Journal of Trauma 2013;(6):541-544
Objective To assess the impact of tranexamic acid on visible and hidden blood loss after the preliminary unilateral total hip arthtoplasty (THA).Methods The study involved 60 patients who received primary unilateral THA due to femoral neck fracture from March 2010 to September 2011.They were 18 males and 42 females,at 58 to 86 years of age (average 74.5 years).They were divided into Group A (n =20),not given tranexamic acid,Group B (n =20),given tranexamic acid in operation,Group C (n =20),given tranexamic acid at preoperative one hour according to stratified random method.Total red blood cell loss,visible red blood cell loss,and hidden red blood cell loss in each group were calculated.Results Visible red blood cell loss in Groups A,B,and C was (95.4 ± 17.7) ml,(45.5 ± 11.5) rnl,and (45.3 ± 8.4) ml respectively.Moreover,difference of visible red blood cell loss was significant between Groups A and B (P < 0.05),but insignificant between Groups B and C (P > 0.05).Hidden red blood cell loss in Groups A,B,and C was (322.4 ± 57.7) ml,(203.8 ±46.6) ml,and (137.6 ± 34.7) ml respectively,with significant difference between Groups A and B (P<0.05) and between Groups B and C (P<0.05).Conclusions Tranexamic acid reduces the visible and hidden blood loss in primary unilateral THA significantly.While tranexamic acid administered at preoperative one hour gains advantage of less hidden blood loss over the intraoperative administration.

Objective To investigate the clinical features of invasive pneumococcal disease (IPD) and the antimicrobial susceptibility of invasive Streptococcus pneumoniae (Sp). Methods The clinical features of 54 children with IPD and the antimi-crobial susceptibility of 54 invasive Sp isolates were retrospectively analyzed from 2009 to 2012. Results The ratio of boys to girls in IPD was 1.35:1. Most of the children with IPD were within 2 years old. Few of the children had the onset in summer. Most of the children were diagnosed with septicemia, followed by meningitis. All of the children had middle or high fever. Forty-four children had an increased white blood cell count and 42 children had an increased C-reactive protein.β-lactam antibiotics was most frequently used in clinics, followed by vancomycin. Most of invasive Sp were resistant to penicillin. Multiple drug resis-tance was common in invasive Sp. Conclusions The incidence of IPD has seasonal difference. The clinical manifestations of IPD are diverse, with septicemia being the most common. The resistant rate to penicillin is high in invasive Sp.
