Assisted vaginal delivery in the obese patient

Area of Science:

• Obstetrics
• Maternal-Fetal Medicine

Background:

• Ventouse and obstetric forceps are established tools for managing the second stage of labor.
• Improper use of these instruments can lead to adverse outcomes.
• Obesity is a growing concern in pregnancy, potentially impacting labor management.

Purpose of the Study:

• To emphasize the importance of proper technique and judgment when using operative vaginal delivery instruments.
• To highlight the increased risks associated with assisted vaginal delivery in obese women.
• To inform clinical decision-making regarding delivery methods in patients with a high BMI.

Main Methods:

• Review of established obstetric practices for instrumental vaginal delivery.
• Analysis of risk factors associated with assisted vaginal delivery, particularly in the context of maternal obesity.
• Discussion of decision-making pathways for intrapartum management.

Main Results:

• Instrumental vaginal delivery (ventouse or forceps) is safe and effective when performed correctly by trained professionals.
• Women with a Body Mass Index (BMI) greater than 30 have a higher likelihood of failed assisted vaginal delivery.
• Obesity is linked to increased risks of intrapartum complications, including shoulder dystocia and postpartum complications like anal sphincter injury and infection.

Conclusions:

• Skilled application of ventouse or forceps, coupled with the judgment to discontinue if unsuccessful, is crucial for safe labor management.
• Clinicians should be particularly cautious with assisted vaginal delivery in obese women (BMI >30), considering a trial in the operating room with a low threshold for cesarean delivery.
• Recognizing obesity-related risks guides appropriate interventions to improve maternal and neonatal outcomes.
