What is the treatment of seizure convulsions in children with clinically undiagnosed epilepsy treated with hyperbaric oxygen? Also pay attention to the safe conditioning before and after the treatment. Among them, the following matters should be noted in the cabin conditioning. For the active phase of epilepsy, we do not recommend hyperbaric oxygen therapy. First of all, pay attention to the aura of convulsions, such as sudden dizziness, headache, palpitation, fear, epigastric discomfort, emotional instability, drowsiness, abnormal sensation or local limb numbness, twitching and so on. Once detected, advise the patient to lie down quietly and decompress out of the cabin. Conditioning during convulsive seizures (no decompression during convulsive seizures to prevent pulmonary pneumonia): quickly untie the sash, lightly press the joints of the limbs, put dental pads or tongue depressor in the mouth, and do a good job of safety protection to prevent secondary trauma. Hold the patient’s jaw up, turn the head to the side, and keep the airway open. All movements should be gentle and quiet, and any stimulation such as sound and light should be reduced. During the treatment, observe and record the seizure: whether there are any prodromal symptoms, whether there is shouting immediately after the seizure, and whether there is any impairment of consciousness. The type of convulsions: the start of the convulsion, whether it is local or generalized, tonic or clonic, or both. The position of the head, trunk and limbs during the seizure, and whether there is upward, downward or squinting eyes, tremor, etc. The patient’s convulsions and their duration should also be recorded. After the seizure stops, decompress the patient from the cabin in time, reassure the patient not to be nervous, and do the corresponding psychological conditioning. Keep the patient warm and calm as much as possible. At the same time, make observations and records: the change of consciousness and pupils after the seizure has stopped, whether the limbs can move, after the consciousness, ask whether you understand the seizure process, whether there are any aura. If a patient with epilepsy (crohn’s disease) falls into a coma, the patient should be conditioned according to the coma routine.
