Peridural anaesthesia or epidural anaesthesia (PDA or EDA for short) is an anaesthetic procedure from the field of regional anaesthesia.
Thanks to its effective pain relief, epidural anaesthesia has proven to be particularly effective during childbirth. Here we are talking about an obstetric epidural.
First, the skin and subcutaneous tissue in the lower back are anaesthetised using a local anaesthetic. The epidural space is then located between two processes of the lumbar vertebrae using a hollow needle and a thin plastic tube (catheter) is inserted.
A pump with a drug reservoir is connected to the catheter. Small amounts of anaesthetic are automatically applied to the spinal nerve roots in the epidural space at regular intervals. You can also operate the pump yourself at the touch of a button to adjust the dose to your own requirements (patient-controlled epidural anaesthesia PCEA). A safety device prevents overdosing.
The dosage of medication is selected so that the labour pain is almost eliminated, but you can still move your legs and walk around with some support ("walking epidural").
An epidural that is already in place can also be used for partial anaesthesia if a caesarean section is necessary.
The epidural is considered to be the most effective method of pain relief during labour.
