BackgroundAn acute respiratory disease (COVID-19), caused by a novel coronavirus (SARS-CoV-2,), has been declared a pandemic by WHO. A surgery on COVID-19 patients not only involves a risk of spread of the disease but also there is a serious concern for the patient's surgical outcomes and resources requirement.AimThe retrospective study is aimed to provide a protocol for pre-operative testing of SARS CoV-2 using RT-PCR in the patient undergoing cardio-thoracic surgeries.Material And MethodsTo analyze the impact of pre-operative testing of SARS- CoV-2 using RT-PCR in the patient undergoing elective cardio-thoracic surgeries. The patient who underwent surgical interventions during the COVID-19 lockdown period was divided into two phases. Phase I (without COVID-19 RT-PCR testing) and Phase II (with pre-operative COVID-19 RT-PCR testing). The retrospective comparison between the two study groups was done using Student t-test, Mann-Whitney U, and Chi square (χ2) test depending upon the clinical variable to be analyzed.ResultsDuring the early phase (phase I), 26 patients underwent cardio-thoracic surgery without COVID-19 RT-PCR test. Whereas, during phase II, all patients were tested for COVID-19 using RT-PCR, preoperatively and a total of 64 surgeries were performed during this phase. One patient planned for CABG was positive on RT-PCR for COVID-19 and was sent to the quarantine ward. The difference in the pre-operative hospital stay between two groups was found to be statistically significant and a significant decrease in the number of PPE kits used, during the phase I.ConclusionAll asymptomatic patients should be tested for COVID-19 using RT-PCR prior to cardio-thoracic surgeries not only to contain the disease but to avoid potential implications of COVID-19 on the perioperative course, without added financial implications.
