How long it takes for a patient with sleeping pill poisoning to wake up after gastric lavage depends on the dose of sleeping pills taken and the degree of poisoning, usually within 1-2 days. There are many types of sleeping pills, the most common being benzodiazepine sedatives. Sleeping pills have a depressant effect on the central nervous system and can help with sleep, as well as being anticonvulsant and relaxing to the transverse muscles. Sleeping pills may cause poisoning if taken in excess. Sleeping pills can mainly suppress the respiratory center, which may cause respiratory failure and circulatory failure. Patients with sleeping pill poisoning may experience drowsiness, confusion, slurred speech, coma, narrow pupils, wet and cold skin, fine and rapid pulse, decreased blood pressure, and signs of shock. Patients with sleeping drug intoxication should be given gastric lavage with water to keep the airway open, and if necessary, a ventilator can be used to assist breathing. Patients with confusion can apply naloxone to counteract the central inhibition caused by benzodiazepines. And actively infuse fluids to promote drug metabolism, most patients can be awake within 1-2 days.
