Asphyxial injury in a term baby is characterized by all except –
Seizures
Differential hypotonia (lower limbs > upper limbs)
Altered sensorium
Difficulty in clearing oral secretions
Effects ofAsphaxia :
Central nervous system-                                                            Cardiovascular

Hypoxic ischemic encephalopathy                                        o Myocardial ischemia
Infarction                                                                                    o Poor contractility
Intracranial hemorrhage                                                           o Tricuspid insufficiency

Seizures                                                                                        o Hypotension
Cerebral edema                                                                    o Pulmonary

Hypotonia                                                                                   o Pulmonary hypertension
Hypertonia                                                                                  o Pulmonary hemorrhage

                                                                                             o Respiratory distress syndrome
 

Renal                            —> Acute tubular or cortical necrosis
Adrenal                        —> Adrenal hemorrhage
Metabolic                    --> SIADH, Hyponatremia, Hypoglycemia, Hypocalcemia, Myoglobinuria
Integument                  -+ Subcutaneous fat necrosis
Hematology                -p DIC
Gastrointestinal          —> Perforation, Ulceration with hemorrhage, Necrosis
During asphyxia the infant may remain hypotonic or change from hypotonia to extreme hypertonia or their tone may appear normal. These changes are seen simultaneously and the change in muscle tone is also of the same degree in both the limbs.
