Objectives:
To evaluate the rate of vaginal delivery attempts (VDA) in breech presentation according to the criteria used to authorize vaginal delivery.
Methods:
The different protocols used in French university hospitals to allow VDA in breech presentation were tested. The rates of VDA were calculated according to the different acceptance criteria in our population.
Results:
Two hundred and seventy-six patients with a single fetus with an estimated weight>2500g, in breech presentation underwent VDA at Lille University Hospital between 2019 and 2021. The local protocol based on cephalo-pelvic confrontation (comparison of biparietal diameter with maternal pelvic measurements) and the estimated fetal weight (EFW) allowed VDA in 55% of patients. When applied to our population, only 3 combinations of criteria « Magnin≥230mm and EFW<3800g », « Magnin≥230mm and EFW<4000g » and « Magnin≥230mm, BIP<100mm, EFW<4000g » allowed TAVB in more patients: 81%, 76% and 74% of patients, respectively. The combined use of a Magnin≥230mm and cephalo-pelvic confrontation in the case of a Magnin<230mm allowed VDA in 86% of cases.
Conclusions:
The combined use of Magnin≥230mm and cephalo-pelvic confrontation in the case of Magnin<230mm is the combination of acceptance criteria that allows a maximum of VDA.

A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.

01:29Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
