Это не бычок, это жевачка
Народ практически не курит - какие-то единицы, и то для них отвели такое специальное место на улице, куда нужно специально идти и которое отлично обозревается из столовой.
По поводу катетеров для диализа я посмотрел в UpToDate и понял, почему имел место быть такой термин, как "не очень инфицированный":
Management of infected cuffed central venous catheters used for hemodialysis (выдержка)
Catheter removal — The authors of several series have suggested that a significant number of catheters can be salvaged assuming that the catheter is functioning properly and that the exit site and tunnel tract are not infected.
One study prospectively evaluated the use of antibiotics given both systemically and "locked" into the catheter in 13 episodes of catheter-related sepsis, due predominantly to Staphylococcus epidermidis and Pseudomonas aeruginosa [40] . The patients were successfully treated with vancomycin or ciprofloxacin. Fever subsided within 48 hours, there were no complications, and no patient required catheter removal.
In comparison, data from larger studies found a lower rate of success, with only 25 to 33 percent of catheters being salvaged with systemic antibiotics alone or the combination of systemic antibiotics and antibiotic lock [15,22] . Serious complications were also noted in 9.7 percent of patients entered in a prospective study of 113 catheter-dependent dialysis patients with S. aureus catheter-related bacteremia who were treated with systemic antibiotics and an antibiotic-lock regimen for three weeks [41] . Attempts at catheter salvage failed in 67 of the 113 patients (59 percent); 10 of 40 patients with persistent fever after institution of this treatment protocol had serious complications [41] . Other studies have also shown that attempted retention of the catheter is an independent risk factor for treatment failure, particularly among patients with Staphylococcus aureus bacteremia [37,42] .
In a prospective observational study of 62 episodes of bacteremia, the catheter was removed immediately in 24 and was left in place during antibiotic therapy in 38 [22] . Only 12 (32 percent) of the catheters left in place were salvaged; the remaining catheters were removed because of persistent fever or recurrent bacteremia caused by the same organism. Despite the low salvage rate, there appeared to be no increase in risk of metastatic complications if the catheter was not initially removed.
It was concluded that a trial of antibiotic therapy alone may be warranted in patients who are hemodynamically stable and do not have tunnel infection, particularly if vascular access is difficult.
