A man in Nan 'an went into shock after being stung by a wasp;

Recently, trees were planted in front of Mr. Hong's house in Guanqiao, Nan 'an. On that day 16: 40, when he was cutting branches, his scalp was bitten by a wasp. Subsequently, he experienced syncope and foaming at the mouth. 17, the family sent Mr. Hong to Guanqiao Hospital.

"When I saw the patient Mr. Hong, there was obvious swelling on the left side of his forehead, poor breathing, lethargy and 93% oxygen saturation. His blood pressure was already very low. " The next day, Wang Chaozhi, vice president of Guanqiao Hospital, said when he met the reporter.

Wang Chaozhi judged that Mr. Hong was in anaphylactic shock caused by wasp sting, so he was given a series of rescue treatments such as anti-shock and anti-allergy. 19, Mr. Hong's vital signs gradually stabilized, blood oxygen saturation returned to normal, and blood pressure rose. On the same day, deputy chief physician He Hongyang, head nurse Zhou, Guo Liyan and other medical staff participated in the rescue.

"Fortunately, Mr. Hong was sent to the hospital in time. If there is any delay, he may even die! " Autumn is the high incidence season of wasp injury. Wang Chaozhi told reporters that in the last month, he has received several cases of bee stings.

Wang Chaozhi said, "Compared with bees, wasps are much more toxic. The composition of wasp venom is more complex than that of bees, which will affect the blood circulation and nerve function of human body and cause systemic inflammatory reaction. He reminded that if you have symptoms such as headache, dizziness and nausea after being stung by a wasp, you should immediately send it to the hospital for rescue. Don't delay, so as not to delay the best treatment opportunity and have an accident.
