From the Guidelines
Vaginal delivery is generally recommended as the preferred method for childbirth when there are no medical complications, as it allows for a natural process that benefits the baby's immune system and triggers important hormonal responses in both mother and baby. The decision between vaginal delivery and C-section should be made collaboratively between the pregnant person and their healthcare provider, considering individual health factors, pregnancy complications, and personal preferences while prioritizing the safety of both mother and baby 1.
Risks of Vaginal vs C-Section Delivery
The risks associated with vaginal delivery and C-section are as follows:
- Vaginal delivery: lower risks of infection, blood loss, and respiratory problems for the baby, but may involve a higher risk of perineal trauma and pelvic floor damage
- C-section: involves surgical risks including infection, blood loss, and complications from anesthesia, but may be necessary and recommended when specific medical indications exist, such as placenta previa, active genital herpes, certain maternal infections, fetal distress, abnormal positioning of the baby, or previous uterine surgery including some C-sections 1
Statistics and Odds Ratio
A study published in 2019 found that the mode of delivery should be determined by obstetric considerations and patient preference, except in cases of active perianal disease and ileoanal pouch or ileorectal anastomosis, where C-section is often preferred 1. Another study published in 2015 found that women who have had a previous vaginal birth have a high probability of VBAC, and physicians should encourage these women to plan for LAC/VBAC unless specific contraindications exist 1.
Comparison of Delivery Methods
The following table summarizes the comparison of vaginal delivery and C-section:
| Delivery Method | Risks | Benefits |
|---|---|---|
| Vaginal Delivery | Perineal trauma, pelvic floor damage | Lower risks of infection, blood loss, and respiratory problems for the baby |
| C-Section | Infection, blood loss, complications from anesthesia | Necessary and recommended when specific medical indications exist |
It is essential to note that the decision between vaginal delivery and C-section should be made on a case-by-case basis, considering individual health factors, pregnancy complications, and personal preferences while prioritizing the safety of both mother and baby 1. The most recent and highest quality study recommends vaginal delivery as the preferred method for childbirth when there are no medical complications, with a focus on collaborative decision-making between the pregnant person and their healthcare provider 1.
From the Research
Risks of Vaginal vs C-Section Delivery
The risks associated with vaginal and C-section deliveries for a healthy child and mother are summarized below:
- Vaginal Delivery:
- Severe perineal lacerations: 0.4% incidence rate 2
- Obstetric anal sphincter injuries: increased odds of nearly 2-fold for nulliparous women delivering by vacuum delivery (adjusted odds ratio, 2.85; 95% confidence interval, 1.19-6.81; P=.019) 2
- Postpartum hemorrhage: 3 times more often in cases of delivery complicated by severe lacerations (adjusted odds ratio, 3.35; 95% confidence interval, 1.76-6.40; P<.001) 2
- C-Section Delivery:
Recommended Delivery Methods
The recommended delivery methods for a healthy child and mother are:
- Vaginal Delivery:
- C-Section Delivery:
Statistics and Odds Ratio
The statistics and odds ratio for vaginal and C-section deliveries are summarized in the table below:
| Delivery Method | Incidence Rate | Odds Ratio |
|---|---|---|
| Vaginal Delivery (severe perineal lacerations) | 0.4% | 2.85 (95% CI, 1.19-6.81; P=.019) |
| Vaginal Delivery (obstetric anal sphincter injuries) | 0.4% | 2.53 (95% CI, 1.46-4.39; P=.001) |
| C-Section Delivery | - | - |
