Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The patient will randomised to one of two treatment groups. The intervention group and the active control group.

Intervention Post delivery of baby, 800 mg ibuprofen diluted in 250 ml normal saline given intravenously over 30 minutes. Oral ibuprofen will be started 12 hours after at 400mg twice daily per orally. This will be continued for 3 days.

Adherence will be monitored to ensure that the medication was given in theatre and medication will be charted in drug chart. If patient is not administered medication or it is refused it will be recorded.
The doses are predetermined doses and will be blinded to patient and staff.
Intervention code [1] 299893 0
Treatment: Drugs
Comparator / control treatment
The active control group

Post delivery of baby, the patient will receive parecoxib 40mg diluted in 250ml normal saline given intravenously over 30 minutes. After 12 hours the patient will receive 200mg of celecoxib twice daily per orally. This will be continued for 3 days.

Adherence will be monitored to ensure that the medication was given in theatre and medication will be charted in drug chart. If patient is not administered medication or it is refused it will be recorded.
The doses are predetermined doses and will be blinded to patient and staff.

Outcomes
Primary outcome [1] 304271 0
24 hour area the curve pain scores.
Pain will be quantified using the 10 point numeric rating scale at 6, 12 and 24 hours and 24 hour area under the curve pain scores made.
Timepoint [1] 304271 0
The time points will be at 6, 12 and 24 hours post-operatively to make 24 hour area under the curve pain scores.
Secondary outcome [1] 341440 0
Amount of rescue analgesia -recorded amount of buprenorphine medication dispensed to patient, recorded amount of tramadol dispensed to patient. Other analgesia medications given to the patient will be recorded.

Timepoint [1] 341440 0
24 hours post operatively
Secondary outcome [2] 343208 0
Quality of Recovery. Validated 9 question QOR with each scored out of 0-2.. Quality of recovery score includes questions of generally well being, support, understanding of instructions, able to go to the toilet, ease of breathing, nausea, vomiting, and pain. This will be done 24 hours post operatively.

Summary
Brief summary
Caesarean Section is a procedure commonly performed in Australia and worldwide. In Western Australia 34% of deliveries are performed by caesarean section. The procedure is performed under neuraxial anaesthesia for 98% of procedures in Western Australia. Pain following caesarean section is common with majority of patients requiring opiate analgesia. Despite being a procedure that is performed commonly there is a wide variety of both intraoperative and postoperative analgesia regimes. There has been conflicting evidence of the value of giving non-steroidal anti-inflammatory drugs (NSAIDs) on reducing post-operative analgesia requirements and whether non-selective NSAIDs are more effective than selective NSAIDs. The study will randomise the patient to receive either a non-selective or selective NSAID and assess whether there is any difference in pain scores. The null hypothesis is that there will be no difference in pain scores in the treatment groups.
