How long dichlorvos poisoning generally stays in the ICU is based on the individual’s poisoning status and vital signs. If the degree of poisoning is mild, the time in the intensive care unit is usually about a few days, such as 5 to 7 days; if the degree of poisoning is more serious, it takes months or even longer in the intensive care unit. If the degree of poisoning is mild, the symptoms of poisoning are relieved, the vital signs are obvious, and the time in the intensive care unit is generally about 5-7 days, the patient’s general condition is stable, i.e., he/she passes through the dangerous period, and he/she can also be transferred to the general ward. If the degree of poisoning is more severe, the symptoms of poisoning worsen and the vital signs are unstable, the patient is always in the dangerous period and can remain in the ICU for more than a few months, and the patient needs to be evaluated to make the next treatment plan and whether to continue to be in the ICU or not. The exact duration of stay in the ICU depends on the patient’s disease state and physical condition, and is evaluated by a regular ICU physician.
