To achieve epidural analgesia or anaesthesia, a larger dose of drug is typically necessary than with spinal analgesia or anaesthesia.Epidural catheter can be continued post operatively to continue analgesia while spinal anesthesia is generally a single shot injection.

For example, very large doses of epidural anaesthetic can cause paralysis of the intercostal muscles and thoracic diaphragm (which are responsible for breathing), and loss of sympathetic nerve input to the heart, which may cause a significant decrease in heart rate and blood pressure.Alternatively, after locating the epidural space with the Tuohy needle, a spinal needle may be inserted through the Tuohy needle into the subarachnoid space.This space (light blue) is filled with cerebrospinal fluid (CSF) and is called the subarachnoid space.A major component of the decreased morbidity and mortality is due to the attenuation of the hypercoagulable response and the associated reduction in the frequency of thromboembolism after neuraxial blockade.This may result in a high block, or, more rarely, a total spinal, where anaesthetic is delivered directly to the brainstem, causing unconsciousness and sometimes seizures.Anticoagulation 3rd Edition. time intervals before and after neuraxial block or catheter removal:. with epidural anesthesia and continued.
The onset of analgesia is slower with epidural analgesia or anaesthesia than with spinal analgesia or anaesthesia.Some operations, most frequently Caesarean section, may be performed using an epidural anaesthetic as the sole technique.Epidural anesthesia is regional anesthesia that blocks pain in certain areas.In addition to blocking the nerves which carry pain, local anaesthetic drugs in the epidural space will block other types of nerves as well, in a dose-dependent manner.
Help About Wikipedia Community portal Recent changes Contact page.Spinal anaesthesia is a technique whereby a local anaesthetic drug is injected into the cerebrospinal fluid.After placement of the tip of the needle into the epidural space, a catheter is often threaded through the needle.
An epidural injection or infusion for pain relief (e.g. in childbirth) is less likely to cause loss of muscle power, but has to be augmented to be sufficient for surgery.Some side effects for the mother include headaches, dizziness, difficulty breathing and seizures.Bupivacaine has caused several deaths by cardiac arrest when epidural anaesthetic has been accidentally inserted into a vein instead of the epidural space.Because of this, a urinary catheter is often placed for the duration of the epidural infusion.
This may be performed using a number of different techniques and for a variety of reasons.They are (usually) much less suitable for analgesia for the neck, or arms and are not possible for the head (since sensory innervation for the head arises directly from the brain via cranial nerves rather than from the spinal cord via the epidural space.).NEVADA STATE BOARD OF NURSING Practice Decision Regarding Removal of an Epidural Catheter Opinion Question: Can a Registered Nurse with the appropriate training.
Epidural analgesia typically involves using the opiates fentanyl or sufentanil, with bupivacaine or one of its congeners.
