Management of Inadvertent Arterial Catheterisation Associated with Central Venous Access Procedures
OBJECTIVE: This study aims to describe the clinical management of inadvertent arterial catheterisation after attempted central venous catheterisation. METHODS: Patients referred for surgical or endovascular management for inadvertent arterial catheterisation during a 5-year period were identified from an endovascular database, providing prospective information on techniques and outcome. The corresponding patient records and radiographic reports were analysed retrospectively. RESULTS: Eleven inadvertent arterial (four common carotid, six subclavian and one femoral) catheterisations had been carried out in 10 patients. Risk factors were obesity (n=2), short neck (n=1) and emergency procedure (n=4). All central venous access procedures but one had been made using external landmark techniques. The techniques used were stent-graft placement (n=6), percutaneous suture device (n=2), external compression after angiography (n=1), balloon occlusion and open repair (n=1) and open repair after failure of percutaneous suture device (n=1). There were no procedure-related complications within a median follow-up period of 16 months. CONCLUSIONS: Inadvertent arterial catheterisation during central venous cannulation is associated with obesity, emergency puncture and lack of ultrasonic guidance and should be suspected on retrograde/pulsatile catheter flow or local haematoma. If arterial catheterisation is recognised, the catheter should be left in place and the patient be referred for percutaneous/endovascular or surgical management
Breast feeding, but not use of oral contraceptives, is associated with a reduced risk of rheumatoid arthritis
Objective: To determine whether breast feeding or the use of oral contraceptives (OCs) affects the future risk of rheumatoid arthritis ( RA) in a community-based prospective cohort. Methods: A community-based health survey (18 326 women) was linked to regional and national registers, and incident cases of RA were identified. All women with a diagnosis of RA after inclusion in the health survey (n = 136) and four female controls for every case, who were alive and free from RA when the index person was given a diagnosis of RA, were included in a case-control study. Data on lifestyle factors at baseline were derived from a self-administered questionnaire. Potential predictors were examined in logistic regression models. Results: 136 women with incident RA were compared with 544 age-matched controls. A longer history of breast feeding was associated with a reduced risk of RA ( OR 0.46 (95% CI 0.24 to 0.91) for women who had breast fed for >= 13 months and OR 0.74 ( 95% CI 0.45 to 1.20) for those who had breast fed for 1-12 months, compared with those who had never breast fed). The protective effect of longer breast feeding remained significant after adjustment for smoking and level of education in multivariate models, and point estimates were protective also when the analyses were restricted to parous women. Neither parity nor OC use had any significant effect on the risk of RA. Conclusion: In this study, long-term breast feeding, but not OC use, was associated with a significant reduction in the risk of RA
