GENERAL ANAESTHESIA AND THE HYPEREOSINOPHILIC SYNDROME: SEVERE POSTOPERATIVE COMPLICATIONS IN TWO PATIENTS

Two patients with markedly increased eosinophil counts developed severe postoperative complications after general anaesthesia. One patient suffered life-threatening Adult Respiratory Distress Syndrome (ARDS), while the other presented with a coagulopathy and less severe respiratory problems. The hypereosinophilic syndrome is described and the possibility of a role of eosinophils in the pathogenesis of tissue injury is discussed. These cases suggest that, in patients with marked eosinophilia requiring general anaesthesia, perloperative steroid cover is advisable. This may reduce or prevent serious lung damage and other complications.
