Which spinal needle has the lowest risk of PDPH?
Conclusion: The pencil-point 25G Whitacre spinal needle causes less incidence of PDPH compared to the classic 25G Quincke needle, and is recommended for use in patients at risk of PDPH.
How common is a post dural puncture headache?
The incidence of PDPH after spinal anesthesia is generally <3. percent, but may occur in up to 9 percent of cases, depending on the type and size of needle used [6-8]. PDPH after lumbar puncture (LP) occurs in approximately 11 percent of cases when a standard, traumatic needle is used [9].
How common is dural puncture?
Accidental puncture probably occurs in about 1% of procedures, so with over 60% of pregnant women receiving epidural analgesia for labor, there are probably 20,000-50,000 obstetric patients with PDPH in the United States each year.
How common is lumbar puncture headache?
Headache after lumbar puncture is a common occurrence (32%) and carries a considerable morbidity, with symptoms lasting for several days, at times severe enough to immobilise the patient. If untreated, it can result in serious complications such as subdural haematoma and seizures, which could be fatal.
What type of needle is recommended for an epidural catheter?
A Tuohy (/tOO-ee/) needle is a hollow hypodermic needle, very slightly curved at the end, suitable for inserting epidural catheters. A 16G Portex Tuohy needle and epidural catheter.
When performing a spinal anesthetic which of the following factors is most likely to contribute to a post dural puncture headache?
Postdural puncture headache is one of the complications following spinal anesthesia and accidental dural puncture. Several modifiable risk factors contribute to the development of headache after lumbar puncture, which includes needle size, needle design, direction of the bevel, and number of lumbar puncture attempts.
Is PDPH serious?
Initial symptom management with simple analgesics, oral or intravenous hydration, and avoidance of the upright position may often be effective. PDPH symptoms can resolve spontaneously within one to two weeks in over two-thirds of patients. In many cases, symptoms are severe and persistent and require intervention.
How can you reduce the risk of post dural puncture headaches?
Insertion of cutting needles parallel to the long axis of the spine is an effective method of reducing the incidence of PDPH and is easily effected in clinical practice. The role of stylet reinsertion when using cutting needles has yet to be fully elucidated.
How common is a wet tap epidural?
The risk of a wet tap occurring during the placement of an epidural is approximately 1.5%. That’s about 1-2 times for every 100 women who get an epidural.
How common is spinal headache after epidural?
The risk of getting a post dural puncture headache after an epidural or spinal injection is between 1 in 100 and 1 in 500 procedures.
What is the most common reason for a lumbar puncture?
A lumbar puncture may be done for various reasons. The most common reason is to remove a small amount of CSF for testing. This can help in the diagnosis of various disorders. The fluid is tested for red and white blood cells, protein, and glucose (sugar).
Why is epidural needle so big?
And the size is also crucial. “Epidural needles are long so that we get better access to the epidural space,” the medical student told the site.
What percentage of epidural punctures cause PDPH?
During epidural placement, inadvertent puncture of the dura mater occurs at a rate of 1.5% (95% CI 1.5–1.5%), and more than half (52.1%; 95% CI: 51.4–52.8%) of these patients develop PDPH [1]. A more recent study showed that the incidence of PDPH after dural puncture with an epidural needle could be as high as 76–85% [2].
What is the success rate of epidural blood patch?
An epidural blood patch is considered the treatment of choice for moderate and severe PDPH, with success rates of 61–98% [71,72,73,74,75]. Based on the success rates, an epidural blood patch seems to be less effective for the obstetric population.
What is the optimal volume of blood for an epidural blood patch?
Although the optimal volume of blood required for a successful epidural blood patch is not known, volumes ranging from 5 to 30 ml have been reported [44,72]. Paech et al. [72] randomized 121 patients to receive 15, 20, or 30 ml autologous blood during an epidural blood patch.
How is epidural saline used to prevent postpartum hemorrhage (PPH)?
Saline injected into the epidural space may decrease CSF loss by reducing the pressure gradient between the epidural and subarachnoid spaces. Therefore, epidural saline has been used to prevent PDPH with variable success.
