Recurrent anaphylactic reaction to intraperitoneal dextran 75 used for prevention of postsurgical adhesions.

The use of intraperitoneal dextran at the conclusion of a gynecologic surgical procedure to prevent postoperative adhesions has increased recently. Although anaphylactic reaction to dextran administered intravenously is well documented, the authors report such a reaction after intraperitoneal administration. The delayed appearance and the continuation of the undesirable reaction until the intraperitoneal reservoir of dextran was removed by means of a culdocentesis are noteworthy. Physicians should be alerted to this potential complication.
