Use of a Triple Prophylactic Strategy to Prevent Post-dural Puncture Headache: An Observational Study.

ObjectivePost-dural puncture headache (PDPH) after an accidental dural puncture is a very common complication of epidural analgesia/anesthesia. We observed the ability of a triple prophylactic method (epidural saline, morphine, and intravenous (IV) cosyntropin) to prevent PDPH and the need for a blood patch. MethodsWe retrospectively evaluated the effect of the combination of epidural saline, IV cosyntropin, and epidural morphine in parturients who had an accidental dural puncture with regard to the PDPH rate and the need for an epidural blood patch. We report a case series of patients with accidental dural puncture who underwent triple prophylaxis and other methods.ResultsThirty-one patients were included in the study. Fourteen cases received triple prophylaxis (45%). Three patients in this group developed PDPH (21%), with two of them requiring a blood patch (14%). Nine patients underwent preventive measures other than triple prophylaxis with a PDPH rate of 55% and one needing a blood patch (11%). Conservative management was used in eight patients with PDPH and blood patch rates of 100% and 62%, respectively.ConclusionThe triple prophylactic regimen of epidural saline, IV cosyntropin, and epidural morphine used after accidental dural puncture exhibits great potential to reduce the incidence of PDPH and the need for blood patch in obstetric patients.

Accidental Dural Puncture Management: 10-Year Experience at an Academic Tertiary Care Center.

The use of spinal catheters for extended periods after accidental dural puncture (ADP) and administration of intrathecal saline via spinal catheters have been advocated to decrease the incidence of postdural puncture headache and the subsequent need for epidural blood patch (EBP), with mixed results observed. We reviewed the medical records of 218 patients with ADP who either had the epidural resited or had a spinal catheter (with or without the administration of intrathecal saline). We compared the incidence of headache and the need for blood patch between these groups. We also assessed complications when a standard lidocaine epidural test dose was administered intrathecally and compared this with complications when a solution normally used for labor combined spinal epidurals was administered. There was no difference in the incidence of postdural puncture headache between the resited epidural group and the spinal catheter group, 68.0% versus 55.9% (odds ratio [OR], 1.7; 95% confidence interval [95% CI], 1.0-2.9; P = 0.07). Resiting the epidural catheter was associated with a significant increase in the number of EBPs when compared with using a spinal catheter, 52.0% versus 20.3% (OR, 4.2; 95% CI, 2.4-7.6; P < 0.001) and when compared with spinal catheters with intrathecal saline, 52.0% versus 8.1% (OR, 12.3; 95% CI, 4.3-35.4; P < 0.001). There was a significant difference in the number of blood patches between normal body mass index patients and morbidly obese patients, 55.2% versus 25.0% (OR, 3.7; 95% CI, 1.2-11.2; P = 0.02). Complications (hypotension prompting pressors, high spinal, and emergency cesarean delivery because of nonreassuring fetal status) occurred more frequently when a lidocaine test dose was immediately administered after ADP versus administering a labor combined spinal epidural solution. Insertion of spinal catheters after ADP and administration of intrathecal normal saline via spinal catheters reduce the need for EBP compared with resiting the epidural. Administration of the standard epidural test dose intrathecally is associated with frequent and significant complications.

Subarachnoid catheter placement after wet tap for analgesia in labor: influence on the risk of headache in obstetric patients

Background and Objectives: The incidence of postdural puncture headache (PDPH) after epidural wet tap for obstetric patients may be as high as 75%. We have studied how subsequent placement of a subarachnoid catheter immediately after confirmation of a wet tap, and leaving the catheter in place for 24 hours affects the incidence of PDPH. Methods: Over a 5-year interval, 115 consecutive patients who had unintentional dural puncture were divided into 3 groups by consecutive assignment. Group A had an epidural catheter placed at another interspace. Group B had a subarachnoid catheter placed for labor analgesia that was removed immediately after delivery. Group C had a subarachnoid catheter that was left in place for 24 hours after delivery. Data were collected retrospectively. The incidence of PDPH and blood patch was compared between groups. Results: The overall incidence of PDPH was 46.9% and need for blood patch 36.5%, significantly less in both subarachnoid catheter groups, 31% in B and 3% in group C, compared with group A (PDPH 81%) ( P < .001). Conclusion: Subarachnoid catheter placement after wet tap in obstetric patients reduces the PDPH rate and does so to a greater extent if left in place for 24 hours after delivery.
