Miami Anesthesia Services (MAS), a private practice of physician anesthesiologists and certified registered nurse anesthetists, provides anesthesia services to women in the labor and delivery unit. Our team of physicians and nurses are dedicated to the care of mothers in the labor and delivery unit 24 hours a day, seven days a week. 

Medical advances have made epidural and spinal anesthesia safe and effective. For labor, we use a continuous epidural. With this method, anesthetics are infused throughout the course of labor through an epidural catheter placed in your lower back. A computerized pump provides anesthetic medications until delivery. If a cesarean section is needed, the epidural placed for labor can be used to provide more anesthesia during the procedure. Your anesthesia care team may also give you a combined spinal­/ epidural. This method administers a small dose of anesthetic into the spinal space at the time of epidural placement. Spinal anesthesia without an epidural is our preferred technique for elective cesarean sections or if our patient does not have an epidural for labor and must have a cesarean section. 

Though rarely serious, you may experience the following side effects: 

  1. Lower blood pressure­- Your blood pressure will tend to be lower. Your anesthesia care team and labor and delivery nurse will monitor your blood pressure closely. They can easily manage these changes. The lower blood pressure will be helpful to patients with high blood pressure from pregnancy.
  2. Lower fetal heart rate- The fetal heart rate may decrease right after the procedure is completed. Almost always, these changes are not serious and go away in a few minutes.
  3. Shivering- Shivering is common during labor and has many contributing causes.
  4. Itching­- You may experience some itching. This is not an allergic reaction. It will go away shortly after a vaginal birth and by 24 hours after a cesarean section.

As with general anesthesia, there are risks involved that could affect the health of the mother and baby. These complications are rare. Most often, they respond to the treatment provided by your anesthesia care team and obstetrician. 

  1. Headache-­ You may experience a headache when you stand that is not present with lying down. The frequency of a headache from epidurals and spinals is low. Less than one out of 200 patients get this type of headache.
  2. Back pain-­ Back pain is common during pregnancy and after labor and childbirth. Mothers with pre­existing back problems may have increased back discomfort after pregnancy, labor, and childbirth. Significant back pain from epidurals or spinals is uncommon. In fact, epidural injections are a common treatment for severe back pain.
  3. Nerve injury-­ Both temporary and permanent nerve injury from epidurals or spinals is extremely rare. Rare problems with loss of sensation or strength in the legs are more likely related to pushing during childbirth, the passage of the baby through the birth canal, or lower back disc problems.
  4. Need for emergency cesarean section-­ Rarely, serious changes in breathing or blood pressure after epidurals will result in the need for an emergency cesarean section.


  1. After the anesthesia care team finishes the epidural, do not lie completely flat on your back until delivery.
  2. You will begin to feel more comfortable within 10 to 15 minutes after the procedure.
  3. Your legs may feel a bit numb and heavy. It is common for one side of your lower body to feel less than the other. Tell your nurse or anesthesia care team if you are unable to move your legs.
  4. The epidural will continue to control your pain throughout labor. As labor progresses, you may experience cramping, pressure, and some discomfort.
  5. To help control labor pain, our epidurals provide you with some control of how much epidural medication you receive. This is called patient controlled epidural analgesia or PCEA. It allows you to self administer additional epidural medication at safe doses and controlled time intervals. 
    1. If you are feeling too much discomfort, there is a button you can push that will give you additional epidural pain medication.
    2. After you push the button, it will take about ten minutes to notice an effect.
    3. The epidural pump is set up so you can receive three extra doses each hour.
  6. Occasionally, to improve pain control, the anesthesia care team will need to repeat the epidural or spinal procedure.

An anesthesia care team member is available on the labor and delivery unit to address your questions and concerns.  We are always available for private consultation or by phone.  We look forward to meeting you and participating in your care.
