A low platelet count means that the number of platelets is lower than normal. Whether or not platelets can be used for surgery depends on the size and type of surgery performed and the degree of platelet reduction. For example, smaller surgeries, such as tooth extraction, general puncture, etc., if the platelet count is mildly or moderately reduced, it is generally tolerable and does not cause severe bleeding. However, for larger surgeries such as open abdomen, craniotomy, open heart surgery, etc., the platelet count is required to be in the normal range. If the platelet count is lowered for major surgery, it is likely to cause serious bleeding during the operation. Of course, in certain emergency situations, such as severe ectopic pregnancy rupture and bleeding, even if the platelet count is reduced, emergency surgery is needed, and at the same time, platelet transfusion is given to the patient while operating so as to ensure the maximum safety of the surgery.
