Abstract

Background

Conservative treatments of post-dural puncture headache (PDPH) may be unsuccessful, and the relief that is provided is frequently insufficient. This study aimed to meticulously explore the analgesic efficacy of the sphenopalatine ganglion (SPG) block when administered alone or in conjunction with the greater occipital nerve block (GONB) for the purpose of treating PDPH and with the aid of transcranial Doppler (TCD) to evaluate the cerebral hemodynamics before and after the block.

This study was conducted on 63 women with post-partum PDPH randomized into the following: control group (Group C = 21 participants), received conservative management; SPG block group (Group S = 21 participants), received conservative management with SPG block; and combined nerve and ganglion block group (Group NAG = 21 participants), received conservative management with SPG block and ultrasound guided GONB. Visual analog score (VAS), modified Lybecker score, and transcranial Doppler (TCD) measures were used to determine PDPH severity at 0 (baseline), 1, 6, and 24 h. Additionally, the three groups’ needs for EBP were noted.

Results

VAS and modified Lybecker scores at 1, 6, and 24 h were statistically significantly lower in S and NAG groups compared to the control group with no statistically significant difference between S and NAG groups. With TCD, the mean velocity (MV) was significantly lower at 1, 6, and 24 h compared to baseline reading in both S and NAG groups. Also, the pulsatility index (PI) was statistically higher at 1, 6, and 24 h compared to baseline readings in S and NAG groups. There was no statistically significant difference regarding the need for EBP.

Conclusions

In terms of headache relief or the need for EBP, there is no difference between individual SPG block or combined SPG block and GONB in the treatment of PDPH.

Transcranial Doppler Ultrasound: A Review of the Physical Principles and Major Applications in Critical Care

Jawad Naqvi, Kok Yap, Gulraiz Ahmad … (2013)

Transcranial Doppler (TCD) is a noninvasive ultrasound (US) study used to measure cerebral blood flow velocity (CBF-V) in the major intracranial arteries. It involves use of low-frequency (≤2 MHz) US waves to insonate the basal cerebral arteries through relatively thin bone windows. TCD allows dynamic monitoring of CBF-V and vessel pulsatility, with a high temporal resolution. It is relatively inexpensive, repeatable, and portable. However, the performance of TCD is highly operator dependent and can be difficult, with approximately 10–20% of patients having inadequate transtemporal acoustic windows. Current applications of TCD include vasospasm in sickle cell disease, subarachnoid haemorrhage (SAH), and intra- and extracranial arterial stenosis and occlusion. TCD is also used in brain stem death, head injury, raised intracranial pressure (ICP), intraoperative monitoring, cerebral microembolism, and autoregulatory testing.

Post-dural puncture headache: part I diagnosis, epidemiology, etiology, and pathophysiology.

David Bezov, Sait Ashina, Richard Lipton (2010)

Post-dural puncture headache (PDPH) is a frequent complication of dural puncture whether performed for diagnostic purposes or accidentally, as a complication of anesthesia. Because both procedures are common, clinicians interested in headache should be familiar with this entity. The differential diagnosis of PDPH is broad and includes other complications of dural puncture as well as headaches attributable to the condition which lead to the procedure. The patterns of development of PDPH depend on a number of procedure- and nonprocedure-related risk factors. Knowledge of procedure-related factors supports interventions designed to reduce the incidence of PDPH. Finally, despite best preventive efforts, PDPH may still occur and be associated with significant morbidity. Therefore, it is important to know the management and prognosis of this disorder. In this review, we will highlight diagnosis and clinical characteristics of PDPH, differential diagnosis, frequency, and risk factors as well as pathophysiology of PDPH.

PDPH is a common complication of neuraxial blockade in parturients: a meta-analysis of obstetrical studies.

Stefan Lucas, P Takeuchi, Carmen Tamayo … (2003)

Postdural puncture headache (PDPH) is an iatrogenic complication of neuraxial blockade. We systematically reviewed the literature on parturients to determine the frequency, onset, and duration of PDPH. Citations on PDPH in the obstetrical population were identified by computerized searches, citation review, and hand searches of abstracts and conference proceedings. Citations were included if they contained extractable data on frequency, onset, or duration of PDPH. Using meta-analysis, we calculated pooled estimates of the frequency of accidental dural puncture for epidural needles and pooled estimates of the frequencies of PDPH for epidural and spinal needles. Parturients have approximately a 1.5% [95% confidence interval (CI) 1.5% to 1.5%) risk of accidental dural puncture with epidural insertion. Of these, approximately half (52.1%; 95% CI, 51.4% to 52.8%) will result in PDPH. The risk of PDPH from spinal needles diminishes with small diameter, atraumatic needles, but is still appreciable (Whitacre 27-gauge needle 1.7%; 95% CI, 1.6% to 1.8%). PDPH occurs as early as one day and as late as seven days after dural puncture and lasts 12 hr to seven days. PDPH is a common complication for parturients undergoing neuraxial blockade.
