How Long Does an Epidural Last?
Once the catheter is in place, the anesthetist can make an epidural pump. The pump sends the epidural solution into the catheter continuously, reducing pain for as long as needed.
The type, amount, and strength of the anesthetic can be changed. You might also be allowed to have control of the medication pump. This is called patient-controlled analgesia. The amount of painkillers is still controlled, so you can’t accidentally overdose. You reduce the dose for second-stage pushing, but it takes some time for the pain relief and numbness to wear off.
When is an epidural placed?
Generally, epidurals are placed when the cervix is dilated to 4-5 centimeters and you are in true active labor.
Conclusion
Epidurals are effective in reducing pain during labor. You must speak with your doctor first to know the side effects of this drug and if you can cope with them.
