Obviate


Definition:

  • (v. t.) To meet in the way.
  • (v. t.) To anticipate; to prevent by interception; to remove from the way or path; to make unnecessary; as, to obviate the necessity of going.

  • (8) Dosage adjustments usually obviate unwanted effects except for paradoxical reactions such as hostility.
  • (9) Using nuclear runoff transcription assays we demonstrated that alpha interferon-mediated induction of transcription of four mRNAs in HeLa monolayer cells needed ongoing protein synthesis and that such a need could be obviated by pretreating the cells with gamma interferon which, by itself, did not induce transcription of these mRNAs.
  • (10) It obviates the need for excision in patients who fulfill the aforementioned criteria.
  • (11) In summary, endoscopic dilatation for postgastroplasty strictures is a useful and effective technique, obviating the need for operative revision in the majority of patients; however, when the stenosis is associated with channel angulation, dilatation is almost uniformly unsuccessful.
  • (12) To obviate this problem, we have covalently attached deferoxamine to high molecular weight carbohydrates such as dextran and hydroxyethyl starch.

  • (15) Gastric resection may still be unavoidable as a diagnostic procedure in a minority of cases and may represent the primary therapeutic procedure in clinically assessed early-stage and low-risk patients, but it cannot be considered mandatory whenever possible merely for debulking purposes or to obviate possible perforation or hemorrhage.
