Symptoms of radiation sickness

summary

Radiation sickness is a systemic disease caused by high dose of ionizing radiation in a short time. Both external and internal irradiation may cause acute radiation sickness, but external irradiation is the main cause. There are three types of radiation that cause acute radiation sickness γ Lines, neutrons and X-rays, etc. Symptoms of radiation sickness? Let's talk about it

Symptoms of radiation sickness

Nausea and loss of appetite occurred in the early stage after irradiation, and the radiation dose may be more than 1Gy; Vomit may be more than 2gy. In case of multiple vomiting, it may be more than 4Gy. If vomiting and diarrhea occur very early, they may be exposed to more than 6gy of radiation.

If vomiting occurs several times within a few hours after irradiation, and severe diarrhea occurs soon, but there is no neurological symptoms, it can be considered as intestinal radiation sickness. We should pay attention to the comprehensive analysis of the initial symptoms and exclude the psychological factors.

The patients with frequent vomiting, disorientation, ataxia, limb tremor and muscle tone enhancement within 1 hour after irradiation can be diagnosed as brain type radiation sickness. If convulsions occur without traumatic factors, it can be confirmed as brain type radiation sickness.

matters needing attention

Early administration of anti radiation drugs is a kind of drugs that can reduce radiation sickness before and after irradiation. It has good effect on moderate and severe radiation sickness. The improvement of microcirculation disturbance in early stage after irradiation can aggravate the damage of tissue and cell, especially in severe radiation sickness. Low molecular dextran can be given intravenously in the first 3 days after irradiation, and dexamethasone and compound salvia miltiorrhiza injection can improve microcirculation, increase tissue blood flow and reduce tissue damage.
