Patient information material Not available in web format, please use the contact details below to request a patient information sheet
Target number of participants 652 participants will be enrolled into the study, 326 in each study allocation arm
Interventions Study participants will be randomly allocated in two study arms, A and B.

Study Arm A:
Will receive a single intravenous single dose gentamicin (160mg) plus metronidazole 500mg 30-60 minutes before operation

Study Arm B:
Will be those who will receive multiple doses; gentamicin (160mg) plus metronidazole (500mg) 30-60 minutes after operation for 24 hours

Simple randomization will be used, 200 similar envelopes will be prepared and inside each of the 100 sealed envelopes there will be small paper marked “study arm A”. The remaining sealed envelopes will contain small papers marked “study arm B”. All sealed envelopes will be mixed thoroughly in a box before selection of an envelope is done. Each study participant will select one sealed envelope and give it to the researcher to open. Then will get antibiotic prophylaxis according to her allocated group.
Primary outcome measure(s) 1. Surgical site infection will be our primary outcome - the assessment for any evidence of surgical site infection will be done 72 hours after caesarian section as well as on follow up days (day 7 and day 30 post caesarean section)
2. Presence of fever (febrile morbidity), signs and symptoms of abdominal wound infection or endometritis will indicate surgical site infection
3. Febrile morbidity will be defined by temperature above 380 C at least 4 hours apart on two or more occasions excluding the first 24 hours after delivery
4. Abdominal wound infection will be defined by partial or total dehiscence or presence of purulent or serous discharge from the wound with indurations, warmth and tenderness
5. Endometritis will be defined by presence of fever (380 C or above) in association with one or more of the following: uterine tenderness or foul smelling lochia
6. In both groups, the bladder catheter will be removed after 24 hours. Wound care will follow the standard scheme in both groups, the occlusive dressing applied in the theatre and removed after 48 hours.
7. Patient will be discharged on day 3 if there was no sign of infection or complication and asked to return on day 7 in order to remove stitches. Then she will come on the day 30 post caesarean section for reassessment. On day 7 and day 30, axillary temperature will be measured, and abdomen and wound will be examined for signs of infection and sutures will be removed on first follow up visit.
Secondary outcome measure(s) No secondary outcome measures
