Introduction: The Coronavirus Disease 2019 (COVID-19) pandemic, caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection, has resulted in a crippled healthcare system worldwide. In this unprecedented situation, it is important to analyse the impact on the vulnerable population of pregnant women, especially those with high-risk pregnancies and those undergoing a Caesarean section (CS). Aim: To analyse the clinical profile, foetomaternal outcomes, and co-morbidities in COVID-19-affected pregnancy cases undergoing a CS. Materials and Methods: This was a retrospective observational study conducted at the Department of Obstetrics and Gynaecology, Government Medical College, and New Civil Hospital in Surat, Gujarat, India during the first wave of the COVID-19 pandemic from April 2020 to December 2020. The study included a total of 65 cases of COVID-19-positive mothers undergoing a C-section. Demographic parameters such as age, obstetric history, details of the C-section (like gestational age at the time of the procedure, indication, and category of the C-section), associated co-morbidities, severity of COVID-19- related symptoms and treatment, neonatal parameters {such as birth weight, Appearance, Pulse, Grimace, Activity and Respiration (APGAR) score, and COVID-19 status of the baby at birth} were analysed. Additionally, a comparison of the C-section rate and complications such as the development of severe anaemia requiring blood transfusion, postoperative development of urinary tract infections, surgical site infections, and the association of hypertensive disorders of pregnancy was conducted between COVID-19-affected and unaffected pregnancies undergoing a C-section during the study period. Data on COVID-19 negative cases were obtained from the monthly labour room statistics submitted to the department. The Chi-square test and Fisher’sexact test were used to compare parameters of the COVID-19 positive and negative groups and a p-value of less than 0.05 was considered statistically significant. Results: Out of a total of 6246 deliveries conducted at the institute during the study period, the CS rate among affected and non affected women was 44.5% (65 out of 146) vs. 32.8% (2006 out of 6100) {p=0.003, Relative Risk (RR) 1.3, 95% Confidence Interval (CI) 1.12-1.62}. The mean age of women with COVID19 undergoing a CS was 25.3 years. The difference in the rate of blood transfusion requirement in COVID-19-affected cases was 9 out of 65 (13.8%) vs. 120 out of 2006 (6%) in COVID-19 negative pregnancies (RR 2.3, 95% CI: 1.2-4.3). The difference in the rate of urinary tract infections in the postoperative period was statistically significant in COVID-19-infected patients, 5 out of 65 (7.7%) vs. 58 out of 2006 (2.9%) in non infected patients (p=0.0451, RR 2.6, 95% CI 1.1-6.4). The prevalence of hypertensive disorders among COVID-19 positive and negative mothers undergoing CS was very high in the present study (16 out of 65, 24.6% vs. 160 out of 2006, 8.1%, RR 3.08, 95% CI 1.9-4.8). Neonatal parameters like low APGAR score at birth were seen in 5 cases (8%), low birth weight in 20 cases (30%), and 3 babies (4.5%) were COVID-19 positive at birth. Conclusion: Higher rates of caesarean sections, increased prevalence of hypertensive disorders of pregnancy, anaemia requiring blood transfusion, and postoperative development of urinary tract infections among COVID-19-affected mothers undergoing a caesarean section.
