The type of first aid given to patients requiring emergency pediatric surgery is decisive for the prognosis in many cases. With this aspect in mind, individual disease pictures from the group of connatal deformities (esophageal atresia, intestinal atresia, gastroschisis, diaphragmatic hernia and defect, myelomeningocele), from emergency surgical situations beyond the neonatal stage (acute abdomen and ileus, esophageal varices, pneumothorax), and accident injuries (blunt abdominal trauma, cranio-cerebral trauma, burns) are selected and the most important first aid measures described. But for all diseases, the general rule for the treatment of all seriously ill children applies: provision of a safe venous access, readiness to intubate, adequate oxygenation and control of the acid-base, water and electrolyte balances.
