Study summary

A prospective, bicentric, randomized, double-blind controlled study including parturients scheduled for elective caesarean delivery under spinal anaesthesia and randomized and assigned to one of the two groups:

Group O ondansetron : receiving Intravenous (IV) ondansetron 0.10 mg/ kg diluted in 5 ml normal saline, 5 min before spinal anesthesia Group C control : receiving IV normal saline 5 ml (control group) 5 min before spinal anesthesia

OBJECTIVE :

To evaluate the efficacy of ondansetron in preventing post-dural puncture headache after spinal anaesthesia for caesarean section.

Read the detailed description

Spinal anesthesia is the most common anesthetic technique used for Caesarean sections. However, it is not denied from complications.

Post-dural puncture headache is a major complication of spinal anesthesia, with an incidence ranging from 1.5% to 36%.

OBJECTIVE :

To evaluate the efficacy of ondansetron in preventing post-dural puncture headache after spinal anaesthesia for caesarean section.

the investigators conducted a prospective, bicentric, randomized, double-blind controlled study over a period of 07 months from November 2023 to june 2024.

the investigators included in the study all parturients:

  • Aged between 18-45 years
  • ASA 2
  • Between 37 and 41 weeks of gestation
  • scheduled for elective caesarean delivery under spinal anaesthesia
  • To be delivered by unscheduled caesarean section whose indication does not involve a vital maternal or fetal emergency, according to the Lucas' classification.

The eligible parturients were randomly assigned to two groups through block randomization using computerized random numbers.

were assigned to one of the two parallel groups to receive either :

  • Intravenous (IV) ondansetron 0.10 mg/ kg diluted in 5 ml normal saline, 5 min before spinal anesthesia : Group O (Ondansetron)
  • Or IV normal saline 5 ml (control group) 5 min before spinal anesthesia : Group C (control)

What researchers measure

Primary outcomes

  1. Incidence of post-dural punction headache (PDPH) during the first seven postoperative days.

    the occurrence of positional headaches at any time postoperatively

    Time frame: 7 days

Secondary outcomes

  1. day of PDPH's occurence

    on postoperatively

    Time frame: 7 days

  2. day of PDPH's resolution

    on postoperatively

    Time frame: 7 days

  3. Headache severity

    assessed by the numerical pain scale from 0 to 10 (0 being no pain and 10 being the maximum unimaginable pain).

    Time frame: 7 days

  4. Need for analgesic treatment due to headaches

    paracetamol or NSAIDs

    Time frame: 7 days

  5. Occurrence of post-operative nausea and/or vomiting

    need of treatement

    Time frame: 7 days

  6. Mean arterial pressure in mmgh

    Mean arterial pressure during hospitalization

    Time frame: 3 days
