Brief summary
Intravenous neostigmine was recently reported as an effective treatment for PDPH for parturients after intrathecal (IT) block which is postulated to be through its central effects on CSF secretion and cerebral vascular tone modulation. Intrathecal neostigmine has been investigated widely and found to be an effective adjuvant to bupivacaine for postoperative analgesia. The objective of the current study is to investigate the possible prophylactic role of intrathecal neostigmine as an adjuvant to bupivacaine in reducing the incidence and severity of post-dural puncture headache in parturients scheduled for an elective cesarean section.
Detailed description
Upon arrival to the operating room standard monitors will be applied and continued all over the operation, an 18G peripheral intravenous (IV) cannula will be inserted, and 15 ml/kg of Ringer lactate solution will be infused. The intrathecal block will be performed via a midline approach into the L3-4 or L4-5 interspaces in a sitting position under strict aseptic condition using a 25-gauge spinal needle after administration of 3 ml of lidocaine 2% (60 mg) as a subcutaneous infiltration, a 2.5 ml of hyperbaric bupivacaine, 0.5 % (12.5 mg) in addition to the content of the prepared study syringe will be mixed and slowly injected. After ensuring sufficient anesthesia level by loss of sensation to pinprick at the T4 level, the surgical procedure will start with continuous hemodynamic monitoring and recording. At the end of the surgery, the parturient will be transferred to the postoperative anesthesia care unit (PACU). Parturients will be transferred to the obstetrics ward after fulfilling the criteria of the modified Aldrete scoring system ≥9. The participants who will be diagnosed to have PDPH Per the previously mentioned criteria will be treated by using oral Panadol extra™ (paracetamol 1gm + caffeine 135 mg) (Manufactured by: Alexandria company for pharmaceuticals & chemical industries under license: GlaxoSmithKline Consumer Healthcare Ltd. Ireland) at 6-hour interval in addition to ensuring good oral or intravenous hydration (2-3 L/day) and bed rest. Severe Intractable headache (VAS ≥ 4) persistent for more than 48 hours with no response to conservative measures will be managed with an autologous epidural blood patch after participant approval and consent signing. Assessment of the quality of the sensory and motor block in terms of the onset and duration will be done at 2 minutes intervals during the first 10 minutes after giving the spinal block, then at 10 minutes intervals until the end of the surgery, and at 15 minutes intervals while being in the PACU.
Interventions
0.5 mg ampule (1 ml) will be diluted in 4 ml dextrose 5% to make a solution of 100 μg/ml, 0.2 ml of this solution will be added to 2.5 ml of hyperbaric bupivacaine 0.5 % used for intrathecal injection.
DRUGDextrose 5%/Nacl 0.9% Inj
one ml of normal saline 0.9 % will be mixed with 4 ml dextrose 5 % in the five-milliliter syringe. 0.2 ml of this mixture will be prepared at a one-milliliter identical syringe.

| Measure | Time frame | Description |
|---|---|---|
| Incidence of post-dural puncture headache | Two times daily for five days after intrathecal block. | any headache that develops within five days of dural puncture and can't be attributed to any other types of headache and mostly is postural in character.usually associated with neck stiffness, nausea, photophobia, and subjective hearing symptoms |
