详细描述
Protokol version 1_01062017 Scientific protocol Caesarean delivery with or without an indwelling bladder catheter. A randomised trial.
Background In 2015, approximately 20% of all pregnant women gave birth by caesarean delivery (CD) in Denmark.
Preoperative preparations for CD include the placement of an indwelling urinary catheter. The rationale behind the procedure is to decrease the risk of surgical injury to a distended bladder and to avoid postoperative urinary retention, but the scientific evidence of the benefit to these matters is not compelling(1). On the other hand, the placement of an indwelling urinary catheter poses a considerable risk of urinary tract infection (UTI) (2), besides the costs associated with delayed ambulation, prolonged hospital stay and catheter associated discomfort to the woman (3, 4) A Cochrane review (1) on indwelling bladder catheter versus no catheter inserted at CD, found that indwelling bladder catheterization was associated with longer time to first spontaneous voiding and more pain/discomfort due to catheterization and/or with first voiding. Furthermore, the women with an indwelling catheter had longer time to ambulation and longer hospital stay. None of the included studies (n=3) in the review reported on bladder injury nor the prespecified criteria for diagnosing UTI and thus no result on UTI as a primary outcome could be obtained. In addition, none of the randomized trials on CD with or without an indwelling bladder catheter were carried out in countries with peri-operative procedures and handling of patients similar to those in Europe.
In a prospective clinical study (5), there were no bladder injuries in 344 women undergoing elective CD without a catheter. UTI was significantly more prevalent in the catheterized group (6%) than in the non-catheterized group (0.58%), P<0.05). In retrospective studies on women undergoing CD with an indwelling catheter, the overall prevalence of bladder injuries is found to be around 0.3%(6, 7).
The aim of this study is to compare the incidence of catheter associated culture- based urinary tract infection (UTI) after elective CD with or without preoperative placement of a urinary catheter.
