Severe asphyxia in infants is usually caused by obstruction of the airway. In the case of newborns, it is usually caused by amniotic fluid obstructing the airway; in the case of babies born after birth, it may be caused by foreign bodies or sputum obstructing the airway. Usually, the first thing to do in this case is to remove the foreign body in the mouth, you can use a suction device to absorb the sputum, apply the Heimlich maneuver, you can put the baby in the palm of one hand, then one hand first hold the baby’s chest, so that the head drops down, the head must be lower than the chest and abdomen, pat the baby’s back with the other hand to promote the airway inside the obstructed foreign body or sputum out of the body. If the blood oxygen still does not rise, a good artificial airway must be established, requiring medical staff to apply tracheal intubation and then give ventilator-assisted breathing. Next is symptomatic treatment, rehydration, prevention of infection and other treatment, if there is shock must also be anti-shock treatment.
