Walking reduces the post-void residual volume in parturients with epidural analgesia for labor: a randomized-controlled study

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 5 2009
C. F. WEINIGER
Background: The post-void residual volume is higher among parturients who received epidural analgesia than those who received no or alternative analgesia. Methods: This prospective, randomized, controlled, non-blinded study was performed in a tertiary referral center labor suite. The post-void residual volume was measured by a transabdominal ultrasound following a voiding attempt. Healthy parturients with low-dose epidural analgesia in active labor were randomized either to walk to the toilet or to use a bedpan for voiding. The primary outcome measure (post-void residual volume in labor) was compared between the study groups. Results: The toilet group (n=34) and the bedpan group (n=28) demonstrated similar post-void residual volumes (212 ± 100 vs. 168 ± 93 ml, P=0.289). Twenty patients (59%) randomized to the toilet group were unable to walk and actually voided in a bedpan. A secondary analysis was performed analyzing the groups as treated. The post-void residual volume was significantly lower in the actual toilet group (n=14, 63 ± 24 ml) vs. the bedpan group (n=48, 229 ± 200 ml), P=0.0052. Thirteen (93%) women who walked to the toilet managed to void before the ultrasound measurement vs. 20/48 (42%) using the bedpan, P=0.001. Fewer women who managed to walk to the toilet required urinary bladder catheterization during the labor than women who used the bedpan (6/14, 43% vs. 36/48, 75%) P=0.028. Conclusion: Women who were randomized to walk to the bathroom with epidural analgesia and were able to do so during labor had a significantly reduced post-void residual volume and a reduced requirement for urinary catheterization.

Nocturia: An austrian study on the multifactorial etiology of this symptom,,

NEUROUROLOGY AND URODYNAMICS, Issue 5 2009

Abstract Aims To identify the different factors contributing to nocturia in a clinical setting. Patients and Methods Three hundred twenty-four patients (133 women, 191 men; mean age 63 years) were entered into this multi-institutional study. When presenting with nocturia we obtained detailed medical history and performed urine analysis, post-void residual volume and renal ultrasonography. Bothersome score and quality of life were evaluated using visual analogue scale and Kings' Health Questionnaire (KHQ), respectively. Patients were asked to complete a 48-hr voiding diary (VD). Nocturia and its associated problems were evaluated using KHQ and VD in conjunction with concurrent health variables. Results Mean nocturia was 2.8 in men versus in 3.1 women. Fifty percent of patients were aged >65 years, 60% had daytime lower urinary tract symptoms (LUTS) as well as nocturia, 33% had cardiac pathologies and 7% had peripheral edema. Principal causes for nocturia were global polyuria in 17%, nocturnal polyuria (NP) in 33% and reduced functional capacity <250 ml in 16.2%; 21.2% had mixed forms of NP and reduced bladder capacity and 12.6% suffered from other causes. Mean bothersome score was higher in women (P,<,0.001) and in patients with NP (P,=,0.012). Quality of life was significantly lower in women (P,=,0.001), in patients aged >65 years (P,=,0.029) and in those with reduced functional capacity (P,<,0.001). Mean voided 24-hr urine was higher in women (P,=,0.033) and in patients aged <65 years (P,=,0.019). Conclusions Nocturia had a high impact on bothersome score, strong associations with poor health and other LUTS. NP was the predominant cause of nocturia. Neurourol.

National survey for intrapartum and postpartum bladder care: assessing the need for guidelines

BJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 8 2004
Mona M. Zaki
Variation in the practice of intrapartum and postpartum bladder care reported by 189 maternity units in England and Wales hospitals was evaluated by analysing the data obtained from a postal questionnaire completed by labour ward managers or heads of midwifery. The survey revealed that there was no consensus of opinion about the diagnostic criteria for postpartum urinary retention and therefore the optimum management for voiding dysfunction remains controversial. In spite of the increasing awareness of the risk management issues involved, the majority of the units were found to be non-compliant with the limited RCOG recommendations currently available. Although further research is needed to develop evidence-based guidelines, all units should be timing and measuring the voided volume and ideally checking the first post-void residual volume to ensure that retention does not go unrecognised.
