<s>[INST] My son had his wisdom teeth removed this morning and was under general anesthesia. Upon waking he began having difficulty. He was hallucinating, and began having what was compared to a panic attack. This continued and the dentist then gave him Valium. He was transported to the ER where he was kept until he woke up on his own and did not have any other issues.  We brought him home and he slept for several hours. Upon waking, he took some pain meds, had a small snack and went back to sleep. He woke up about an hour later and when he got up to use the restroom, began having a full blown attack, with hyperventilation, and incoherent. The question that I have is, is this common? Why does this keep happening and what should we do? [/INST] Thank you for asking query in this forum. Recovery period from general anesthesia (GA)varies from person to person. Till 12 hours after waking from GA there could be some symptoms like hypoxia (low oxygen- breathlessness), Hypo or hypertension, Hypercarbia - also symptoms like breathlessness, restlessness, anxiety (which you may describe as panic attack) etc. are not uncommon.  If antisemitic is given, symptoms like dissociation or disorientation can also be seen. But everything should wear off within 12 hours. Let him take enough rest. You can give one more dose of Valium tab 10 mg after 12 hours of first dose and let him have a good sleep. He will be well soon. </s>
