Article:

Background: The novel coronavirus infectious disease-2019 (COVID-19) is a global pandemic involving many countries and has affected more than seventy-nine million people worldwide, with greater than a million deaths in the current scenario. Aims: The aim of the study is to improvise perioperative obstetric healthcare in a tertiary healthcare center. Settings and Design: This is a retrospective case series of parturients infected with COVID-19. Materials and Methods: We present a case series of COVID-19-infected parturients. There is no evidence that pregnant women are more likely to become seriously affected by coronavirus, yet these groups of patients are vulnerable to infection. Hence, the objectives in the management of such patients which includes caring for the range of the asymptomatic to critically ill women in the peripartum period and protection of healthcare providers from exposure to the disease while treating them while treating them is of paramount importance. Results: There is limited literature available about the effect of this disease and the risk of complications in pregnancy. The variables affect the respiratory system and exacerbate the susceptibility to infections. This complicates or delays the diagnosis in COVID-19-infected parturients, which affect their clinical outcome. Thus, there is a need on focused and optimal management in a tertiary healthcare center. Of the total 109 lower segment cesarean section patients in our hospital, there were only two maternal and neonatal deaths among the 12 emergency cases performed. Conclusions: Collaborative efforts are imperative among experts such as anesthesiologists and obstetricians to tackle the impact of this disease. There must be surveillance systems in place for reporting maternal and fetal data during this pandemic.
