ETHERIZATION AND ASPHYXIA.

Birth asphyxia.

Diving and Asphyxia

A harbor seal (Phoca vitulina) exhales and submerges. As water contacts its nostrils, there is a rapid increase in firing of the cardiac vagus nerve and the heart rate drops from 100 to 10 beats per minute. Simultaneously, an alpha-adrenergic peripheral vasoconstriction results in a central shift in oxygen-rich blood volume. The inferior vena cava enlarges to the size of a football. Though card...

Association between serum interleukin-1β levels and perinatal asphyxia

Objective: Asphyxia  is  a  major  cause  of  acute  mortality  and  chronic  neurologic  disability  in  neonates. We sought to  define  the  predictive  values  of  serum  concentrations  of  interleukin-1β  in  newborns  with perinatal asphyxia to see if there is a relation between interleukin-1β (IL-1β) levels to the short term neurological deficit.  Methods: This was a prospective (case-co...

Traumatic asphyxia

BACKGROUND Traumatic asphyxia is probably much more common than the surgical literature shows and should always be kept in mind as a possible complication of injuries of the chest and abdomen. AIMS Traumatic asphyxia or Perte's syndrome results from a severe crush injury causing sudden compression of the thorax. During a 3-year period, we treated five cases of traumatic asphyxia, which we rep...
