ABSTRACT
OBJECTIVE: To determine whether two percent lignocaine gel can reduce the perception of pain during Vabra endometrial aspiration. DESIGN: Randomised, double-blind placebo-controlled trial. SETTING: Women's Health Directorate, Warrington Hospital NHS Trust. POPULATION: Women were referred to the endometrial sampling clinic for the investigation of pre and postmenopausal vaginal bleeding. METHODS: Randomisation to either pre-sampling intrauterine two percent lignocaine gel or an inert gel. Patients, recruiters and assessors were blinded to the gel used. MAIN OUTCOME MEASURES: The difference between the study groups in the proportion of women who, after Vabra sampling, recorded a pain score of > or = 6 out of 10 on a visual analogue scale. RESULTS: Three hundred and eight women were randomised, 284 (92%) completed a pain scale before and immediately after the procedure. After the procedure, 84 women (30%) recorded a pain score of > or = 6, 38 (26%) received anaesthetic and 46 (33%) an inert gel. The difference in the proportion of women recording a pain score of 6 or above between the two study groups was not significant (relative risk (RR) for the anaesthetic gel = 0.79 95% CI, 0.55, 1.14). CONCLUSIONS: Intrauterine application of 2% lignocaine gel did not significantly reduce the frequency with which women experienced unacceptable levels of pain or anxiety during endometrial aspiration compared with placebo.

Cord serum sodium levels were estimated in 96 full term singletons delivered by spontaneous vertex delivery. Thirty-two of these infants had cord serum sodium of less than 130 mmol/L and 64 had cord serum sodium of > or = 130 mmol/L. Serum bilirubin estimated on day 4 of life of the babies demonstrated mean unconjugated bilirubin levels of 105.7 mmol/L (S.D.:87.04) and 89.4 mmol/L (S.D.:66.18) in the hyponatraemic and normonatraemic groups respectively (P < 0.05). The study also demonstrated a higher cord sodium and lower serum unconjugated bilirubin in those babies whose mothers did not receive parenteral fluids. It is suggested that hyponatraemia should be excluded in the aetiology of neonatal jaundice.
