A case of clostridium perfringens gas gangrene panophthalmitis developed after a penetrating eye injury. The affected eye became amaurotic, but the panophthalmitis was controlled by minimal surgical debridement and systemic antibiotic therapy with penicillin, fucidic acid and metronidazole. Elective enucleation was performed 15 days after the trauma for cosmetic reasons. The enucleated eye was examined histopathologically and showed massive retinal necrosis but no signs of bacteriae.
To examine the association between intended mode of delivery and severe postpartum haemorrhage.
A retrospective cohort study.
Material from a nationwide study in Denmark.
Danish women giving birth in 2001-08.
We compared use of red blood cell transfusion by intended mode of delivery in the total population (n = 382 266), in low-risk nulliparous women (n = 147 132) and in women with a previous caesarean delivery (n = 25 156).
Red blood cell transfusion within 7 days of delivery.
In the total population the crude transfusion rates for women with planned caesarean delivery and intended vaginal delivery were 2.24 and 1.75%. After adjustment for maternal age, body mass index, birthweight, smoking, parity, number of infants and previous caesarean delivery, the risk of red blood cell transfusion was significantly lower in women with planned caesarean delivery compared with intended vaginal delivery (odds ratio 0.82; 95% CI 0.73-0.92; P
Traditionally, Denmark has had a high rate of allogeneic red blood cell transfusion caused by a liberal transfusion practice despite the existence of restrictive guidelines. We established a Patient Blood Management programme in a tertiary hospital and report the results of the implementation of evidence-based transfusion practice.
Red blood cell transfusion quality indicators were compared with the evidence-based guideline at hospital and department level. Based on this evaluation, wards were selected for interventions targeting doctors and nurses. The implementation process was monitored by transfusion quality and utilization data over a 3-year period with totally 166 341 admissions in 98 960 mixed, adult medical and surgical patients.
At the hospital level, transfusion above the upper guideline limit decreased from 23 to 10% (P
Transfusion-associated anaphylaxis (TAA) is a severe adverse reaction reported to occur in 1:9000-90,000 transfusions. According to the Danish Registration of Transfusion Risks (DART), the frequency is 1:300,000 transfusions, which suggests insufficient reporting of TAA in Denmark. Our aims were to identify possible cases of TAA, to characterize their symptoms and tryptase levels and to investigate the reporting of TAA to the haemovigilance systems.
We reviewed 245 patients with suspected allergic reactions during anaesthesia and surgery, investigated at the Danish Anaesthesia Allergy Centre (DAAC). Based on the outcome of this investigation, the patients were classified as DAAC positive (confirmed hypersensitivity to identified agent, n = 112), or DAAC negative (no confirmed hypersensitivity, n = 133). Data on case history, details of blood transfusion and results of laboratory and clinical investigations were collected. TAA cases were identified according to the recommendations of the International Society of Blood Transfusion (ISBT).
Ten possible TAA cases (30% of all transfused patients) were identified, all DAAC negative. The frequency of elevated serum tryptase, hypotension and male sex was significantly higher among these cases compared with the remaining DAAC negative (P
In 1993, 2 cases of urinary tract infection (UTI) caused by verotoxin-producing Escherichia coli were diagnosed at Rigshospitalet in Copenhagen, Denmark. Neither of the patients had any previous history of diarrhea. We suggest that E. coli strains isolated from UTI be examined for the production of verotoxin when hemolytic uremic syndrome is clinically suspected.
