Which of the following is the most important side effect of epidural opioids?

The four classic side effects are pruritus, nausea and vomiting, urinary retention, and respiratory depression. Numerous other side effects have also been described. Most side effects are dose-dependent and may be more common if the opioid is administered intrathecally.

Where is intrathecal space?

Also known as the subarachnoid space, the intrathecal space is the fluid-filled area located between the innermost layer of covering (the pia mater) of the spinal cord and the middle layer of covering (the arachnoid mater).

Which drug should never be given intrathecal?

Accidental administration of any vinca alkaloids—especially vincristine but also vinblastine, vinorelbine, or others—via the intrathecal route is nearly always fatal.

What drugs can be given intrathecal?

Currently there are only three medications approved by the US Food and Drug Administration (FDA) for use via the intrathecal route, ie, morphine, ziconotide, and baclofen. Morphine targets opioid receptors within the dorsal horn.

One injection will last up to 24 hours after it is given. An intrathecal injection can reduce the amount of other medicines needed to control your pain.

What is the difference between intrathecal and epidural?

Intrathecal administration is delivered directly into the CSF and into the superifical spinal cord; epidural administration diffuses through the dura into the CSF, and thus has a slower onset of action.

Is there a difference between a spinal tap and an epidural?

What’s the difference between a spinal and epidural and a combined spinal-epidural? The space around this sac is the epidural space. Spinal anesthesia involves the injection of numbing medicine directly into the fluid sac. Epidurals involve the injection into the space outside the sac (epidural space).

Is a spinal different than an epidural?

Back to epidurals and spinals: The main difference is the placement. With an epidural, anesthesia is injected into the epidural space. With a spinal, the anesthesia is injected into the dural sac that contains cerebrospinal fluid. The direct access means that a spinal gives immediate relief.

What is in the epidural?

Epidural medications fall into a class of drugs called local anesthetics, such as bupivacaine, chloroprocaine, or lidocaine. They are often delivered in combination with opioids or narcotics such as fentanyl and sufentanil in order to decrease the required dose of local anesthetic.

Can you have permanent back pain from epidural?

Myth: Epidurals can cause permanent back pain or paralysis in the mother. Fact: Serious complications from an epidural, including paralysis, are extremely rare.
