Pentazocine with rectal diclofenac versus pentazocine alone for pain relief following caesarean delivery in Enugu, Nigeria: A randomized controlled trial.

OBJECTIVE: To measure postoperative pain relief following the use of rectal diclofenac combined with intramuscular pentazocine compared with intramuscular pentazocine alone in patients undergoing a caesarean delivery. METHODS: This single-blind randomized controlled trial enrolled pregnant women that had a caesarean section at the Enugu State University of Science and Technology Teaching Hospital, Enugu, Nigeria. Study participants were randomized to receive either 100 mg of rectal diclofenac given every 12 h plus 30 mg of intramuscular pentazocine given every 6 h (group A) or 60 mg of intramuscular pentazocine given every 6 h (group B). The primary outcome was the level of pain as measured using a visual analogue scale. The secondary outcomes were the level of satisfaction with pain relief and need for rescue analgesia. RESULTS: A total of 200 participants were randomized equally into the two groups. Participants in group A had significantly better pain control and satisfaction over the 48 h after surgery compared with group B. Significantly more of group B required rescue analgesia for breakthrough pain compared with group A. CONCLUSION: Rectal diclofenac combined with intramuscular pentazocine was significantly better at controlling pain compared with pentazocine alone in the first 48 h following caesarean section.Trial registration number: PACTR202107706925314 at www.pactr.org on 28 July 2021.

The magnitude and predictors of cervical squamous intraepithelial lesions among women in Enugu, Nigeria: a cross-sectional study of women in a low-resource setting.

Introduction: the prevalence of cervical squamous intraepithelial lesion is not well appreciated in most low-income countries. The study aimed to determine the level of awareness, prevalence and the pattern of squamous intraepithelial lesions and predictors for abnormal Pap smear reports (development of pre-malignant lesions of the cervix) among women attending various clinics in a tertiary health facility in Enugu, Nigeria. Methods: a cross-sectional study of 207 female patients attending various clinics of Enugu State University Teaching Hospital, Parklane, Enugu between June and August 2017 was undertaken. Structured interviewer-administered questionnaires were used for data collection while cervical smears were collected from the patients and sent for cytology. Data analysis was done using the Statistical Package for the Social Sciences (SPSS) version 22.0. The results were presented as means, standard deviations, frequencies and proportions. Pearson´s Chi-square test was used to test for associations between categorical variables and statistical significance was set at a p-value of < 0.05. Results: the levels of awareness of cervical cancer and the screening methods among the respondents were 76.8% and 36.7% respectively. The overall knowledge of cervical cancer and its screening was poor (6.8% and 29.0% respectively). The prevalence of pre-malignant lesions of the cervix among the respondents was 15.0% with low grade squamous intraepithelial lesion (LGSIL) having the highest frequency (38.7%). Among all the other risk factors for the development of premalignant lesions of the cervix among the respondents, a report of abnormal pap (positive) smear report was significantly associated with only age ≥35 years (χ2=5.723; p=0.017). The same age of 35 years and above also correctly predicted abnormal Pap smear reports among other factors (AOR = 3.02, 95% CI = 1.16 - 7.89, p = 0.024). Conclusion: the awareness of cervical cancer and cervical cancer screening was high but the overall knowledge on cervical cancer and its screening was very poor among the respondents. The prevalence of pre-malignant lesions of the cervix was high, and the commonest abnormal smear was LGSIL. Only age 35 years and above correctly predicted the occurrence of abnormal Pap smear reports among the respondents.
