Eight-hour versus 24-h urethral catheter removal following elective caesarean section for reducing significant bacteriuria: A randomized controlled trial.

ABSTRACT:

Background

There is no consensus on the preferred time to remove urethral catheter post caesarean section.

Aim

To compare rate of significant bacteriuria and urinary retention following 8-h (study) and 24-h urethral catheter removal (control) post elective caesarean section.

Methods

A randomized controlled trial of eligible participants that underwent elective caesarean section under spinal anaesthesia between March 2019 and November 2019 was conducted. Participants (150 in each arm) were randomly assigned (1:1 ratio) to either 8-h or 24-h group. Primary outcome measures included rates of significant bacteriuria 48-h post-operatively and acute urine retention 6-h post urethral catheter removal. Analysis was by Intention-to-treat. (www.pactr.org:PACTR202105874744483).

Results

There were 150 participants randomized into each arm and data collection was complete. Significant bacteriuria was less in 8-h group (3% versus 6.0%; risk ratio (RR): 0.85 CI: 0.60 to 5.66; p = 0.274), though not significant. Acute urinary retention requiring repeat catheterisation was significantly higher in 8-h group (11(7.3%) versus 0(0.0%); RR: 0.07; CI: 0.87 to 0.97; p = 0.001). Mean time until first voiding was slightly higher in 8-h group (211.4 ± 14.3 min versus 190.0 ± 18.3 min; mean difference (MD): 21.36; CI: -24.36 to 67.08; p = 0.203); but patient in this group had a lower mean time until ambulation (770.0 ± 26.1 min versus 809 ± 26.2 min; MD: -38.8; CI: -111.6 to 34.0; p = 0.300). The 8-h group were significantly more satisfied (82/150 (54.7%) versus 54/150 (36.0%); p = 0.001).

Conclusions

An 8-h group was associated with significant clinical satisfaction and acute urine retention compared to 24-h removal. The timing of urethral catheter removal did not affect rate of significant bacteriuria and other outcomes.

Project description:BackgroundThe OptiBIRTH study incorporates a multicentre cluster randomised trial in 15 hospital sites across three European countries. The trial was designed to test a complex intervention aimed at improving vaginal birth after caesarean section (VBAC) rates through increasing women's involvement in their care. Prior to developing a robust standardised model to conduct the health economic analysis, an analysis of a hypothetical cohort was performed to estimate the costs and health effects of VBAC compared to elective repeat caesarean delivery (ERCD) for low-risk women in four European countries.MethodsA decision-analytic model was developed to estimate the costs and the health effects, measured using Quality Adjusted Life Years (QALYs), of VBAC compared with ERCD. A cost-effectiveness analysis for the period from confirmation of pregnancy to 6 weeks postpartum was performed for short-term consequences and during lifetime for long-term consequences, based on a hypothetical cohort of 100,000 pregnant women in each of four different countries; Belgium, Germany, Ireland and Italy. A societal perspective was adopted. Where possible, transition probabilities, costs and health effects were adapted from national data obtained from the respective countries. Country-specific thresholds were used to determine the cost-effectiveness of VBAC compared to ERCD. Deterministic and probabilistic sensitivity analyses were conducted to examine the uncertainty of model assumptions.ResultsWithin a 6-week time horizon, VBAC resulted in a reduction in costs, ranging from €3,334,052 (Germany) to €66,162,379 (Ireland), and gains in QALYs ranging from 6399 (Italy) to 7561 (Germany) per 100,000 women birthing in each country. Compared to ERCD, VBAC is the dominant strategy in all four countries. Applying a lifetime horizon, VBAC is dominant compared to ERCD in all countries except for Germany (probabilistic analysis, ICER: €8609/QALY). In conclusion, compared to ERCD, VBAC remains cost-effective when using a lifetime time.ConclusionsIn all four countries, VBAC was cost-effective compared to ERCD for low-risk women. This is important for health service managers, economists and policy makers concerned with maximising health benefits within limited and constrained resources.

Project description:Caesarean section is associated with moderate-to-severe postoperative pain, which can influence postoperative recovery and patient satisfaction as well as breastfeeding success and mother-child bonding. The aim of this systematic review was to update the available literature and develop recommendations for optimal pain management after elective caesarean section under neuraxial anaesthesia. A systematic review utilising procedure-specific postoperative pain management (PROSPECT) methodology was undertaken. Randomised controlled trials published in the English language between 1 May 2014 and 22 October 2020 evaluating the effects of analgesic, anaesthetic and surgical interventions were retrieved from MEDLINE, Embase and Cochrane databases. Studies evaluating pain management for emergency or unplanned operative deliveries or caesarean section performed under general anaesthesia were excluded. A total of 145 studies met the inclusion criteria. For patients undergoing elective caesarean section performed under neuraxial anaesthesia, recommendations include intrathecal morphine 50-100 µg or diamorphine 300 µg administered pre-operatively; paracetamol; non-steroidal anti-inflammatory drugs; and intravenous dexamethasone administered after delivery. If intrathecal opioid was not administered, single-injection local anaesthetic wound infiltration; continuous wound local anaesthetic infusion; and/or fascial plane blocks such as transversus abdominis plane or quadratus lumborum blocks are recommended. The postoperative regimen should include regular paracetamol and non-steroidal anti-inflammatory drugs with opioids used for rescue. The surgical technique should include a Joel-Cohen incision; non-closure of the peritoneum; and abdominal binders. Transcutaneous electrical nerve stimulation could be used as analgesic adjunct. Some of the interventions, although effective, carry risks, and consequentially were omitted from the recommendations. Some interventions were not recommended due to insufficient, inconsistent or lack of evidence. Of note, these recommendations may not be applicable to unplanned deliveries or caesarean section performed under general anaesthesia.

Project description:BackgroundControlling massive haemorrhage from morbidly adherent placenta (MAP) at caesarean section is a major surgical challenge to obstetricians. This study compares different intra-operative interventions to control haemorrhage from morbidly adherent placenta and its impact on maternal morbidity.MethodsRetrospective analysis was done for baseline characteristics, intra-operative and postoperative complications of 125 patients with morbidly adherent placenta who had elective CS at 35-38 weeks gestation in the period from 01/2012 to 01/2017. The included patients were categorized into three groups according to intra-operative interventions they had for controlling bleeding; Group A (n = 42) had only balloon tamponade, Group B (n = 40) had balloon tamponade and bilateral uterine artery ligation, in Group C (n = 43) all cases were managed by bilateral uterine artery ligation and inverting the cervix into the uterine cavity and suturing the anterior and/or the posterior cervical lips into the anterior and/or posterior walls of the lower uterine segment using the cervix as a natural tamponade.ResultsThere were no differences of baseline characteristics of patients in all groups. Group C had significantly better outcomes as compared with groups A and B; less total blood loss (Group C 2869.5 ml vs Group B 4580 ml, Group A 4812 ml, P < 0.001), less requirement of blood transfusion more than 4 units (Group C 4/43, Group B 10/40,Group A 12/42, P < 0.02), significant reduction in prolonged hospital stay over 10 days (Group C 2/43, Group B 9/40,Group A 14/42, P < 0.001) and lower risk of coagulopathy (Group C 4/43, B 8/40, A 9/42), visceral injuries (Group C 4/43 vs B 8/40, A 10/42,P < 0.01) and need for hysterectomy (Group C 4/43 vs B 11/40, A 13/42,P < 0.001).ConclusionA combination bilateral uterine artery ligation and using the cervix as a natural tamponade are very effective and simple methods in controlling bleeding resulting from separated placenta accreta.Trial registrationThe findings are part of the research project registered in ClinicalTrials.gov NCT02590484 .

Project description:IntroductionApproximately 25% of all babies in North America are delivered via Caesarean section (C-section). Though a common surgical procedure, C-section recovery can be painful. Opioids, specifically codeine, are commonly used to ease pain; however, its active metabolite, morphine, passes into breast milk, and may produce unwanted side effects in neonates; therefore, alternatives to opioids are being sought. Reiki is an ancient Japanese form of healing where practitioners transfer healing energy through light touch and positive healing intention. Although 1.2 million Americans use reiki to reduce pain or depression, there is a lack of strong evidence supporting its effectiveness. A recent systematic review showed existing studies to be of poor methodological quality, with the common limitation of lack of blinding. To overcome this issue, the authors used distant reiki to assess its effectiveness in reducing pain following an elective C-section.MethodsIn this randomised, double-blinded study, women who underwent an elective C-section were allocated to either usual care (control, n=40) or three distant reiki sessions in addition to usual care (n=40). Pain was assessed using a visual analogue scale (VAS). The primary endpoint was the Area Under the VAS-Time Curve (AUC) for days 1-3. Secondary measures included: the proportion of women who required opioid medications and dose consumed, rate of healing and vital signs.ResultsAUC for pain was not significantly different in the distant reiki and control groups (mean ± SD; 212.1 ± 104.7 vs 223.1 ± 117.8; p=0.96). There were no significant differences in opioid consumption or rate of healing; however, the distant reiki group had a significantly lower heart rate (74.3 ± 8.1 bpm vs 79.8 ± 7.9 bpm, p=0.003) and blood pressure (106.4 ± 9.7 mmHg vs 111.9 ± 11.0 mmHg, p=0.02) post surgery.ConclusionDistant reiki had no significant effect on pain following an elective C-section.
