About

Post-caesarean maternal infectious morbidity is still a big challenge despite prophylactic antibiotics and preoperative vaginal cleansing with povidone-iodine use in reduction of post-caesarean endometritis.Povidone iodine has been found to cause significant irritation to the vaginal mucosa especially in females with iodine hypersensitivity necessitating the study of efficacy of normal saline which has minimal side effects in the prevention of post caesarean complications

Full description

BACKGROUND: Maternal infectious morbidity is a common complication of caesarean section and is the third leading cause of maternal mortality in Nigeria and account for 15% of maternal death worldwide. Post-caesarean maternal infectious morbidity is still a big challenge despite prophylactic antibiotics and other modalities adopted to prevent it. Recently, preoperative vaginal cleansing with povidone-iodine (PI) was recommended in reduction of post-caesarean endometritis, but this may lead to significant irritation to the vaginal mucosa resulting from allergic reactions in females with iodine hypersensitivity. Normal saline (NS) is an effective cleaning solution and doesn't have allergic effect on healthy tissues. It is accessible, non-irritant, and less expensive in contrast to povidone iodine.

AIM: To compare the difference in the incidence of postoperative vaginal irritation symptoms and the rate of postoperative infections after using Povidone iodine versus Normal saline solution in vaginal cleansing before caesarean section at the Alex Ekwueme Federal University Teaching Hospital Abakaliki.

METHODOLOGY: This was a randomized controlled trial involving two hundred and twenty four (224) consenting pregnant women undergoing caesarean section in AE-FUTHA. These women were grouped into two arms; group 1 (Vaginal cleansing with povidone iodine) and group 2 (vaginal cleansing with normal saline solution). Both groups received prophylactic antibiotics and anterior abdominal wall scrubbing. Subsequently, the researcher and assistant reviewed the patients for infectious

morbidity daily during ward rounds till discharge and vaginal irritation symptoms 24hours postoperatively, and daily during ward round till discharge.

DATA ANALYSIS: Data was analyzed using statistical Package for Social Science (IBM SPSS) software (version 20, Chicago II, USA). Continuous variables were presented as mean and standard deviation (Mean ± SD), while categorical variables were presented as numbers, frequencies and percentages. Student t- test (t-test) was used for comparison between groups for quantitative variables while the chi- square was performed for comparing categorical variables. Relative risk and 95% confidence interval were calculated for outcome measures. A difference with a P value of < 0.05 was taken to be statistically significant.

224 participants in 2 patient groups

Povidone group

Active Comparator group

Description:

Hundred (100) ml of 5% povidone iodine was poured into a sterilized bowl (galipot). Three pieces of gauze held with sponge holding forceps was dipped into the sterilized bowl containing 100mls of 5% povidone iodine and was allowed to be well soaked with 5% povidone iodine and thereafter used to swab the vulva in 360 degrees. one gram of ceftriaxone and 500mg of metronidazole was given prior to the procedure.

Treatment:

Drug: Povidone-Iodine

Normal Saline

Experimental group

Description:

Hundred (100) ml of Normal saline was poured into a sterilized bowl (galipot). Three pieces of gauze held with sponge holding forceps was dipped into the sterilized bowl containing 100mls of Normal saline and was allowed to be well soaked with Normal saline and thereafter used to swab the vulva in 360 degrees. one gram of ceftriaxone and 500mg of metronidazole was given prior to the procedure.

Treatment:

Drug: Normal Saline
