The experience of cocaine and 'crack' use among participants involved in (n = 19) or exiting (n = 10) prostitution in Glasgow, Scotland, is described. In-depth semi-structured qualitative interviews enquired about their use and experience of using cocaine and their perception of its effect on working practice. Twenty-three of 29 participants had used cocaine and 15 out of 29 had used crack cocaine. In reality, freebase not 'crack' was being self-manufactured from cocaine powder. Participants considered that cocaine use in the city was not restricted to prostitution but was reflected throughout the drug scene generally. One possible reason suggested for this was a perceived reduction in heroin availability at a time when cocaine was increasingly readily available. There was no evidence from participants to suggest that they were first introduced to cocaine through prostitution. Most participants believed that using cocaine did not affect how they worked, however they perceived that other prostitutes were prepared to take more risks to support their cocaine use and had to work longer hours to finance a cocaine habit compared to financing a heroin habit. Only participants recruited from the east end of the city spoke about their desperation for money and the sexual risks that they were prepared to take to buy cocaine. Harm-reduction messages should address the sexual and personal risks that some female prostitutes may be taking to support their cocaine use. Treatment and support services in the city, traditionally established to work with problematic heroin users, need to adapt to the changing drug trends among female drug users, including those involved in prostitution, and offer appropriate treatment options and harm-reduction advice to cocaine users. 相似文献

A case series and technique of transradial cardiac catheterization with cardiac biospy are described. Transradial cardiac catheterization is perceived to be limited to arterial procedures. Using the veins of the forearm, we have converted many previous femoral arterial/venous cardiac procedures to a transradial/forearm approach. Retrospective review of patients undergoing transradial procedures with concurrent cardiac biopsies was undertaken. A convenience sample of transfemoral procedures with biopsies performed by the same operator was identified for comparison. Coronary angiography/left heart catheterization was performed using standard transradial/femoral approaches. A 7 Fr introducer sheath was placed via a large median forearm or femoral vein. Right heart catheterization was done using a 120 cm balloon-tipped catheter and endomyocardial biopsy was performed with a 7 Fr biotome. Both groups were then compared for baseline characteristics and procedural events. Transradial (n = 8) and transfemoral (n = 12) procedures were all done for postcardiac transplantation management. There was no crossover between groups. Durations of the radial procedures (median, 73 min; range, 40-95) were similar to transfemoral procedures (median, 68 min; range, 45-105). No procedural complications were reported. Endomyocardial biopsy plays an important role in the diagnosis of transplant rejection and identification of pathological processes that cause myocardial dysfunction. Transradial cardiac catheterization has some clear advantages over a transfemoral approach. Bilateral cardiac catheterization with concurrent cardiac biopsy is technically feasible using a transradial/forearm approach. This approach offers an alternative approach for selected patients in need of cardiac biopsy. 相似文献

OBJECTIVES: This study compares the transradial versus transfemoral approach to combined right- and left-heart catheterization. BACKGROUND: Central venous access from peripheral veins has been a historically useful technique. Although the need for right-heart catheterization has been considered an exclusion for transradial catheterization, we have combined a peripheral approach to the central venous system with radial arterial access which permits bilateral heart catheterization using a transradial approach. METHODS: Over an 18-month period all right-heart catheterizations done in conjunction with arterial access were reviewed. Salvage procedures, mixed site access, and biopsy procedures were excluded. Radial procedures were performed using radial artery access and a forearm vein. Femoral procedures used femoral artery/vein. Demographics, procedural information, and postprocedural complications including those requiring vascular ultrasound or transfusion were recorded and used for comparison between groups. RESULTS: Total of 175 femoral/105 radial cases done by 4 operators met criteria for comparison. Both groups had similar procedural indications and age. Procedural durations were shorter (P < .01) with radial 70 +/- 5.0 min (+/-95% CI) vs. femoral 75 +/- 5.4 min (+/-95% CI). Crossover was noted in several patients from both groups; radial procedures (n = 2) failed due to previous shoulder trauma. Femoral crossover to radial involved difficult arterial access. Complications related to access site occurred in 12 femoral and 0 radial patients. CONCLUSIONS: Using the forearm for central venous access appears safer than using the femoral vessels. Transradial catheterizations can be done in combination with forearm venous access procedures with excellent results and enhanced patient safety. 相似文献
