Epidural analgesia often leads to an increase in the number of catheterisations because of the modifications that result in the physiology of the urinary tract. These catheterisations lead to lower urinary tract infections. Our study on 312 patients shows that: under epidural analgesia it is necessary to carry out catheterisation 3.6 times more frequently; urinary tract infections are 2.6 times more frequent under epidural analgesia; the incidence of urinary tract infection multiplies in accordance with the number of catheterisations whether there has been epidural analgesia or not; a single prophylactic dose of 3 g of amoxycillin can avoid three-quarters of these infections.
硬膜外镇痛常常会导致导尿次数增加，因为其会对尿路生理机能产生影响。这些导尿操作会引发下尿路感染。我们对312名患者的研究表明：在硬膜外镇痛情况下，导尿频率需要增加3.6倍；硬膜外镇痛时尿路感染的发生率高出2.6倍；无论是否进行硬膜外镇痛，尿路感染的发生率都随着导尿次数的增加而上升；单次预防性服用3克阿莫西林可避免四分之三的此类感染。
