Article Summary
Vaginal births are the most common way that babies are born. During labor, your body works to open the cervix and move your baby through the birth canal (vagina). Your obstetric team will monitor you and your baby to make sure your safety is a priority. This article explains what happens during a vaginal birth, the different options for managing labor pain, and how anesthesia professionals, such as Certified Registered Nurse Anesthetists (CRNAs), keep you safe and comfortable.

When do vaginal births happen?

Vaginal births usually happen when: 

  • You and your baby are sufficiently healthy as determined by your obstetric provider. 
  • Your baby is positioned head-down.
  • Labor is progressing normally. 
  • There are no medical concerns, either acute or chronic, that would make a C-section, also called a cesarean section, or cesarean delivery, the safer option.

Labor usually begins on its own or close to your due date, but your obstetric provider may recommend starting labor earlier (induction), if it is the safest option for you or your baby. Induction of labor can happen for several reasons:  

  • Worsening preeclampsia  
  • Medical reasons that put you and your baby’s safety at risk  
  • Trial of labor after cesarean birth   
  • Baby is overdue  
  • You and your obstetric team want control over the situation  
  • Mutually agreed upon date with obstetric provider  

Sometimes labor changes without warning. If any worries arise for you or your baby, your obstetric team may recommend an episiotomy or an assisted vaginal delivery. This includes forceps or a vacuum device being used to help with the delivery of the baby. An episiotomy or an assisted vaginal delivery may be needed if: 

  • Birth is happening quickly, and the perineum has not had enough time to stretch slowly. 
  • The baby’s health is at risk, and they need to be delivered quickly. 
  • You are too tired to keep pushing safely.
  • The baby is in a position that makes it difficult for them to rotate or move down the birth canal (vagina). 
  • You are pushing for a long time, but the baby isn’t progressing down the birth canal as expected.

What pain relief options are available during a vaginal birth?

There are many ways to manage pain during labor. The best option depends on your medical history, labor progress, and your birth plan/personal preferences. 

Non-medication pain relief options include: 

  • Breathing and relaxing techniques 
  • Walking or changing positions 
  • Hydrotherapy, such as a warm shower or tub, if available 
  • Aromatherapy, like smelling the calming scent of lavender

Pain relief options during labor and delivery

Type of pain relief What is it? Advantages Disadvantages Things to know
Epidural A thin plastic tube is placed in the lower back in a space next to the spinal canal where the nerves exit More medication can be given through the tube. You lose feeling from your waist to your feet. Takes about 10-15 minutes to set up Cannot use the restroom while the epidural is in, a urinary catheter is used; you are unable to walk; may take 10-15 minutes to set up The most common form of pain relief
Spinal An injection into the spinal fluid in the lower back Works fast and can be set up quickly Only given one time and lasts about 2 hours; can cause itching Most common in a planned C-section
Combined spinal-epidural A combination of an epidural and a spinal Works fast and more medication can be given if needed Can cause itching Provides the benefits of both spinal and epidural anesthesia
Intravenous (IV) pain relief Pain medications go through an IV in your arm or hand Fast to set up and works within minutes Can make the baby drowsy or experience slow breathing after birth; can cause nausea and vomiting; does not completely eliminate pain Medications for IV pain relief are typically opioids and cannot be used by everyone; this is not a substitute for spinal and epidural anesthesia
Local anesthesia (paracervical nerve block) An injection to numb a small part of the body during labor Provides targeted pain relief Does not last long and does not cover a large area Your obstetric provider may numb the nerve that is in charge of the pain around the vagina and rectum
Nitrous oxide A gas to breathe in; often called “laughing gas” Provides pain relief in about 30 to 50 seconds Common side effects include nausea, vomiting, drowsiness, and dizziness Not a replacement for a stronger pain relief option, like an epidural

What can I expect during vaginal birth?

It is no secret that labor is painful. The uterus tightens and releases to help the baby move down the birth canal. These are also called contractions. Contractions often feel like strong menstrual cramps or even diarrhea cramps. These can be felt in the back, lower abdomen, and pelvis.  

This is what you can expect from your obstetric team and anesthesia professional, such as a Certified Registered Nurse Anesthetist (CRNA), before and during labor:  

Before labor 

  • Review your medical history and pregnancy 
  • Discuss your birth plan and pain management options 
  • Answer your questions

During labor 

  • Monitor your blood pressure, heart rate, temperature, and breathing 
  • Monitor your baby’s heart rate and your contractions 
  • Check your cervix every so often to see how labor is progressing 
  • Help you stay comfortable, informed of your progression, and support you on whatever pain management plan you choose 

Labor happens in three stages: 

  • First stage is when your cervix softens, thins, and opens to 10 centimeters. 
  • Second stage is when you start pushing during your contractions, and your baby is born! 
  • Third stage is when your placenta is delivered, usually between 5 to 30 minutes after birth of the baby.

What if my labor doesn't go as planned?

Every labor is different, no matter if it is your first or fifth baby. Sometimes labor slows down or concerns develop for you or your baby. 

If this happens, your obstetric team may recommend: 

  • Changing your position or using medications to help the labor move faster (such as Pitocin®)
    • Note that patients may receive Pitocin® even if their labor is progressing as expected; this medication helps increase the contraction force of the uterus and decrease bleeding risk.
  • An assisted vaginal delivery using an episiotomyforceps, or a vacuum device
  • A C-section, if it is the safest option

Your obstetric team will explain why a recommendation is being made and will answer your questions. Whether you’re delivering your baby vaginally or via C-section, your anesthesia professional is there to help manage your pain, keep you and your baby safe, and provide emergency support if needed.
