There is no direct causal relationship between cough and the success rate and feasibility of painless abortion. However, since the symptoms of cough may affect the operation of abortion, whether painless abortion can be performed is mainly related to the severity and control of cough: 1. If it is only an ordinary mild cough, not accompanied by symptoms such as fever and coughing phlegm, and the condition has been controlled, painless abortion can be performed. If the cough persists or is accompanied by coughing sputum, fever, nausea, vomiting and fatigue, acute respiratory tract infections such as acute bronchitis and pneumonia are suspected, blood tests for routine blood, C-reactive protein and calcitoninogen can be drawn, and chest X-ray and CT examination of the lungs are also needed to find the lesion. If this is the acute inflammation period, this is not suitable for painless abortion and is a contraindication to abortion. It is recommended to treat the inflammation and arrange abortion after it has improved. Cough alone is only a relative contraindication to painless abortion, while other severe acute inflammation of the respiratory system is an absolute contraindication. Therefore, in case of cough or other serious respiratory diseases, it is recommended to visit the respiratory department in time to give timely symptomatic treatment, and it is safer to perform painless abortion after the condition gradually decreases and the inflammation subsides.
