Effect of a perineal protection device in vacuum-assisted births-a prospective randomized controlled interventional trial.

Background: Birth tears are common after vaginal birth with a prevalence of up to 85%, especially in vaginal-assisted births. Because birth trauma can cause physical and psychological short-term and long-term maternal morbidity, it is essential to improve maternal outcomes at birth.

Objective: This study aimed to evaluate the effect of a perineal protection device on the rate of spontaneous birth tears in the posterior compartment in vacuum-assisted births and the feasibility and safety of the device.

Evaluation of two rapid commercial assays for detection of Streptococcus agalactiae from vaginal samples.

Introduction: Streptococcus agalactiae, also known as group B streptococci (GBS), is associated with invasive infections in neonates. Identification of GBS vaginal colonization in pregnant women before delivery is essential for treatment with antibiotics to prevent intrapartum vertical transmission to the newborn. This study was designed to evaluate applicability of two rapid real-time PCRs in comparison to standard culture identification.

Association between levator ani muscle avulsions and technique of vacuum extraction - a prospective exploratory study.

Aims Of The Study: Trauma of the levator ani muscle in the form of partial or complete avulsions is common after vaginal births, especially after vaginal-operative births. As there is little information available regarding associations between the technique of vaginal-operative births and levator ani muscle trauma, we aimed to evaluate the association between the process of vacuum extraction and the occurrence of levator ani muscle trauma.

Methods: As part of a prospective cohort study at the University Hospital of Zurich between March 2017 and April 2019, we sub-analysed vacuum extractions in nulliparous women with singletons in vertex presentation ≥36+0 gestational weeks.

Association between the side of levator Ani muscle trauma and fetal position at birth - a prospective observational study.

Introduction: Trauma of the levator ani muscle (LAM) is common after vaginal birth and can most reliably be diagnosed by 3-dimensional (3D) translabial ultrasound (TLUS). Multiple risk factors are known in general, but not in association to a specific side of the body. Therefore, our aim was to evaluate different impact factors which cause LAM trauma on either side of the body or bilateral by focusing on the fetal position at birth.

Prediction of levator ani muscle avulsion by genital tears after vaginal birth-a prospective observational cohort study.

Introduction: Visible birth tears and levator ani muscle (LAM) trauma are common after birth. For the diagnosis of LAM trauma ultrasound evaluation is advisable. As ultrasound equipment and trained personnel are not available everywhere at all times, we aimed to evaluate whether specific overt birth tears are an indicator for LAM trauma.

[Association of Birth Trauma with the Implementation of Obstetrical Monitoring Tools: A Retrospective Cohort Study].

Introduction: Lacerations are common in vaginal births. They can result in immense physical and psychological morbidity. Ongoing efforts are being made to reduce birth trauma.
