About this study

Official title: The Effect of Caffeine Ingestion in Prevention of Postoperative Ileus After Caesarean Section: A Randomized Controlled Trial

Many trials have been made to prevent paralytic ileus , including administration of prokinetic drugs , early resumption of feeding, gum chewing and adequate pain control. Unfortunately, none of these strategies has been completely successful. Recently the effect of caffeine on prevention of postoperative ileus after caesarian section was researched. That's why this study is designed to determine the efficacy of caffeine in prevention of postoperative ileus after caesarean section.

Read the detailed description

-Study design: This study will include 600 women undergoing their caesarean section. The study aims will be explained to all women and an informed written consent will be taken. All recruited women will be distributed into two groups according to a computerized randomization table. The researcher consecutively will open sequentially numbered, opaque, sealed envelopes containing cards with letters either letter (C) or letter (N), Cards with letter (C) will represent the group who will receive the caffeinated coffee and cards with letter (N) will represent the group who will receive the decaffeinated coffee

Procedure:

  • For all women, the anesthetic used will be Marcaine® Spinal heavy 0.5% and fentanyl and for post-operative pain, ketorolac will be used.
  • Through Pfannenstiel incision, transverse lower segment uterine incision is done, with the duration of the surgery not exceeding 90 minutes
  • women will not be permitted to drink or eat, except for the drink offered by the researcher, till passing flatus. Early ambulation will be encouraged.
  • A stethoscope will be used to detect the first intestinal movement each hour after the surgery. The women will be advised to notify the researcher when they pass both flatus and feces.

Intervention:

  • The intervention plan will be performed within the first 24 hours after the surgery.
  • Provided by the researcher within 10 minutes, patients will drink 100cc coffee with 1 tea spoon added sugar at 3, 6 and 9 hours after the surgery, and the control group will drink 100cc decaffeinated coffee with 1 tea spoon added sugar at the same intervals.
  • No other liquid will be allowed till passage of flatus and feces in the first day of surgery.
  • Nescafe Gold ® coffee (5gm per 100cc water containing 170 mg of caffeine) will be used for all the women in the intervention group. Nescafe Gold DECAF coffee (5 gm per 100cc water containing 5-10 mg of caffeine) will be used for all the women in the control group.
  • Statistical Package:
  • Data analysis will be performed by Statistical Package for the Social Science (SPSS) 16.0 using descriptive statistics tools, including mean, standard deviation and figures. A t-test will be used to compare mean values of the two groups. P-values, smaller than 0.05, were considered statistically significant.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

A change in the number of hours for women to pass flatus for the first time after an elective caesarean section (time frame: patients will drink 100cc coffee with 1 tea spoon added sugar at 3, 6 and 9 hours after the surgery. The women will be advised to notify the researcher when they pass flatus.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03815877, which also lists 15 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
