title: Intrauterine lignocaine as an anaesthetic during endometrial sampling: a randomised double-blind controlled trial.
abstract: OBJECTIVE
  To evaluate the effectiveness of intrauterine lignocaine as an anaesthetic during endometrial sampling.
  
  
  METHODS
  Prospective, randomised, double-blind, placebo-controlled trial.
  
  
  METHODS
  Outpatient gynaecological minor operation unit in a public hospital.
  
  
  METHODS
  Two hundred premenopausal women scheduled for endometrial sampling because of abnormal uterine bleeding.
  
  
  METHODS
  Transcervical intrauterine instillation of 5 mL of 2% lignocaine or 5 mL of normal saline before performing endometrial sampling with vacuum aspirator.
  
  
  METHODS
  Evaluation of pain associated with the procedure using a visual analogue scale.
  
  
  RESULTS
  The use of intrauterine lignocaine reduced pain during suction curettage in endometrial sampling.
