Obstetric outcomes
Surgical time was significantly shorter in patients who did not have a
UC inserted (46.1 min [IC95% 43.4 – 48.8] vs 51.1 min [IC95%
49.4 – 52.8], p = 0.005), being the mean time difference 5.0 min
[IC95% 1.5 – 8.4].
Figure 1 and Table 2 display time to first micturition, time to
mobilization, time to first oral intake and time to hospital discharge.
When comparing those patients who underwent CD with no UC placed or when
it was early removed (before 6 h after the surgery) to those with a
later removal, time to first micturition after surgery, time to first
oral intake and time to hospital discharge were significantly shorter in
the first group (p <
0.001, p < 0.001 and p = 0.032, respectively). Time to
mobilization, was shorter in the first group, although not being
significantly different between groups (p = 0.068).
When comparing those patients with no UC with those with UC placed,
regardless its time of removal, no differences in the occurrence of
uterine atony (p = 0.976) were observed. Moreover, no bladder lesions
were recorded in either group. Urinary retention was more frequently
observed in patients in which UC was not placed compared to those
patients in which it was placed (21.9 % [IC95% 11.7 – 32.0] vs
8.9 % [IC95% 5.2 – 12.6], p = 0.004) and consequently
intermittent catheterization was also more frequent in the first group
(39.7 % [IC95% 27.6 – 51.8] vs 19.6 % [IC95% 14.4 – 24.7],
p < 0.001).
