Incidence, complications, and costs of peripheral venous catheter-related bacteraemia: a retrospective, single-centre study.

BACKGROUND: Peripheral venous catheter (PVC) complications occur on average in approximately half of patients, necessitating premature PVC removal, suspending administration of ongoing therapies, and catheter replacement. AIM: To estimate the current incidence, complications, and costs of bloodstream infection (BSI) attributable to PVCs. METHODS: Patients with PVC-related BSI (cases) were matched with patients without PVC-related BSI (controls). FINDINGS: From January 1st, 2018 to March 31st, 2020, a total of 9833 out of 113,068 patients visiting the emergency department (9%) were hospitalized in a medical ward after insertion of a PVC. Among them, 581 (6%) had at least one positive blood culture. Twenty-five (4%) of these were judged as having a PVC-related BSI. Major complications were noted in nine patients. One patient presented severe sepsis requiring admission to intensive care unit for eleven days followed by thoracic (T4-T7) spondylodiscitis requiring prolonged antimicrobial therapy. Another patient developed mitral valve endocarditis also requiring prolonged antimicrobial therapy. One patient developed a pre-sacral abscess three months after initial PVC infection and required hospital readmission for 19 days for drainage. Median (interquartile range) hospital stay costs were €11,597 (8,479-23,759) for cases and €6,789 (4,019-10,764) for controls, leading to median additional costs of €5,587. CONCLUSION: Though the risk of developing PVC-related BSI in patients admitted to medical wards may seem low, complications of PVC-related BSI are severe, and associated mortality remains high. The financial resources used to treat these complications could be better spent on prevention, including the use of high-quality materials and technologies, and improved training of healthcare providers.

Photography tele-transmission by regular ambulance staff for the management of mild traumatic injury: the NiCEPHORE randomised-controlled trial.

BACKGROUND: Handling emergency calls in French emergency medical call centres (EMCCs) can be challenging considering the frequent lack of relevant information. Tele-transmission device use in regular ambulances seems like a good solution to provide the EMCC physician with a more accurate assessment of the scene, particularly for mild traumatic injury (MTI). We measured the impact of ambulance staff tele-transmitted photography on prehospital dispatching optimisation for patients calling the EMCC with MTI. METHODS: We conducted a prospective, single-centre, randomised-controlled trial comparing two groups of patients calling the EMCC with MTI who were or were not allocated to photography tele-transmission by ambulance staff. The primary outcome was the proportion of patients referred away from the nearest hospital (left at home for outpatient care; referred to a higher-level hospital; handled by a medical intensive care ambulance for advanced pre-hospital care) used as a marker of better orientation. RESULTS: Between 29 April 2019 and 21 July 2020, 165 patients were randomised and 152 analysed. Photography tele-transmission resulted in better patient dispatching (24/73 [33%] patients in the intervention group vs 9/79 [11%] patients in the control group, OR 3.80 [1.63-8.90]; p = 0.03), without increasing the proportion of patients initially left at home for outpatient care and visiting an ED within 10 days for secondary trauma-related care (1/14 [7%] vs 1/4 [25%], OR 0.25 [0.01-24.1]; p = 0.41). The proportion of patients unnecessarily referred to an ED was 7% [4/59 patients] in the intervention group vs 16% [12/75 patients] in the control group (OR 0.38 [0.09-1.36]; p = 0.10). CONCLUSION: Photography tele-transmission by regular ambulance staff could improve the dispatching of patients calling French EMCCs with MTI. Trial registration The study is registered with Clinicaltrials.gov (NCT04034797).

Peripheral venous catheter colonization after skin disinfection with 0.5% aqueous sodium hypochlorite, preceded or not by one application of 70% ethanol (DACLEAN): a single-centre, randomized, open-label, pilot study.

Few data are available on the efficacy of 0.5% aqueous sodium hypochlorite (SH) for skin disinfection before peripheral catheter insertion. A total of 239 patients were randomly assigned to either one application of SH alone or one application of SH preceded by one application of 70% ethanol (ET-SH). Catheter colonization, defined as a catheter tip culture growing >1000 cfu of a micro-organism per millilitre, occurred in 29 patients (33% of 89 colonizations per 1000 catheter-days) in the SH group and in 31 patients (33% of 126 colonizations per 1000 catheter-days) in the ET-SH group.

[Posology of amikacin in newborn infants, adapted to the postconceptional age]. / Posologie de l'amikacine chez le nouveau-né, adaptée à l'âge post-conceptionnel.

Two consecutive studies of amikacin plasma levels were performed in 63 and 64 neonates whose postconceptional age (PCA) ranged from 26 to 45 weeks. The first study, using a dose of 7.5 mg/kg every 12 hours, permitted to establish a dosage related to PCA. Half-life elimination of amikacin was strongly correlated with PCA (r = -0.42, p = 0.0009). The apparent volume of distribution was correlated with none of the variables studied. The mean volume of distribution was 640 +/- 190 ml/kg. From these data, the inferred dosage was 10 mg/kg, given at intervals of time predetermined as a function of PCA. A second prospective study proved the value of this PCA adapted dosage. The maximal concentrations obtained were higher (21.6 +/- 5.9 vs 18.5 +/- 4.6 micrograms/ml, p less than 0.001), the nadir concentrations were not significantly increased (5.7 +/- 3.1 vs 5.2 +/- 3.7 micrograms/ml, NS) and the number of nadir concentrations outside the desired interval of 2-8 micrograms/ml was smaller (p less than 0.01).
