Brief Summary

Postdural puncture headache (PDPH) is a common complication, following neuraxial techniques. The obstetric population is particularly prone to PDPH. Therefore, treatment of PDPH is a key issue in obstetric anesthesia. Dexmedetomidine is a highly selective, centrally acting α2-adrenergic agonist with analgesic and anxiolytic effects. Moreover, it decreases cerebral blood flow (CBF) in humans and animals secondary to cerebrovascular vasoconstriction. It has been used via the intranasal and inhalational routes for many purposes including premedication, sedation and postoperative analgesia. Because of its desirable properties, we hypothesized that dexmedetomidine nebulization could be effective in the treatment of patients suffering from PDPH after caesarean section.

Outcome Measures

Primary Outcomes (2)

  • visual analogue score (VAS)

    using the 10-cm visual analogue score (VAS) where score 0 is no headache and 10 is the worst imaginable headache with 1-3 classified as mild, 4-6 moderate, and 7-10 severe our aim to get VAS \</= 3 at 24 hour from starting treatment

    24 hour

  • Lybecker headache classification score

    our aim to get Lybecker score \< 2 at 24hour following treatment Lybecker et al. classification of PDPH score 1: Mild PDPH where daily activities slightly restricted. Patient is not bedridden. No associated symptoms\*. Score 2:Moderate: Daily activities significantly restricted and most of the day patient is bedridden with or without associated symptoms. Score 3:Severe Daily activities completely restricted, patient is bedridden all the day and always with associated symptoms Associated symptoms include: Nausea, vomiting, vertigo, dizziness, tinnitus Photophobia, diplopia, and neck stiffness.

    24 hour

Secondary Outcomes (2)

  • the effects of nebulized dexmedetomidine on cerebral blood flow by using Trans-Cranial Doppler (TCD)

    72 hours

  • adverse effects related to nebulized Dexmedetomidine

    72 hours

Study Arms (2)

Control group

PLACEBO COMPARATOR

received ultrasonic nebulization of 4mL 0.9% saline twice daily for 3 days

Other: 0.9% Saline Nebulization

Dexmedetomidine group

ACTIVE COMPARATOR

received ultrasonic nebulization of 1 µg/kg dexmedetomidine diluted in 4mL 0.9% saline twice daily for 3 days. The intervention will be continued until achieving a VAS score ≤3 and Lybecker et al. classification score \<2 and or for a maximum of 72 hours. Patients in this group who achieved the target scores before 72 hours will be given 4ml of saline 0.9% nebulization to maintain blinding.

Drug: Dexmedetomidine Nebulization

Interventions

ultrasonic nebulization of 1 µg/kg dexmedetomidine for PDPH treatment

Dexmedetomidine group

nebulization of 4mL 0.9% saline

Control group

Masking Details
Participants will not be aware of their group assignment, and the medications will be prepared by an anesthetist who is not involved in the study. The anesthetist who will assess the participants after the intervention is blinded to the group allocation and single experienced operator who is unaware of patient group and study purpose will perform all Trans-Cranial Doppler (TCD) measurements.
