Objective
To determine whether the injection of local anaesthetic through the hysteroscope at outpatient hysteroscopy, with or without endometrial biopsy, will reduce abdominal pain and increase patient acceptability of the two procedures.
Design
Prospective randomized double‐blind placebo‐controlled study.
Setting
Outpatient hysteroscopy clinic, Royal Hospital for Women, Sydney, Australia.
Subjects
100 women undergoing outpatient hysteroscopy with or without endometrial biopsy.
Interventions
Randomization into two groups: local anaesthetic (group 1) and placebo (group 2). Upon introduction of the hysteroscope into the cervical os, 5 ml of 2% plain lignocaine (group 1) or normal saline (group 2) was introduced via the channel in the hysteroscope. After 2 min, the hysteroscopy and endometrial biopsy (where indicated) were conducted in the usual manner.
Main outcome measures
The degree of pain experienced and the acceptability of the procedures were assessed using visual analogue scales.
Results
99 women underwent hysteroscopy (49 in group 1 and 50 in group 2) with 92 also undergoing endometrial biopsy (45 in group 1 and 47 in group 2) Both groups were homogeneous for age, parity, menopausal status and subjective pain tolerance assessment. Group 1 found both the hysteroscopy and endometrial biopsy to be less painful and more acceptable, but these differences were not statistically significant. Four subgroups were analysed: nulliparous (group A), no past vaginal delivery (group B), postmenopausal (group C), and no previous dilatation and curettage (group D). Local anaesthetic reduced the pain at hysteroscopy in groups A, B and C and at endometrial biopsy in all groups, with groups B, C, and D at endometrial biopsy reaching statistical significance (P = 0.05, 0.03, and 0.04, respectively).
Conclusions
Topical intra‐uterine anaesthetic injected through the hysteroscope results in: (1) a trend towards a reduction in pain for both hysteroscopy and endometrial biopsy, and (2) a significant reduction in pain during endometrial biopsy in women who have not had a previous vaginal delivery, or dilatation and curettage, or are postmenopausal.
The results of a study of 101 consecutive second trimester terminations by Dilatation and Evacuation (D & E) under ultrasound control is presented. All had a Cervagem pessary inserted into the vagina prior to the procedure. The PGE1 analogue was assessed as 'effective' in 97% of patients. Concomitant ultrasound resulted in no patient leaving the operating table with retained products. The high efficacy of the single pessary associated with a low incidence of side-effects makes this combination the method of choice for nearly all second trimester terminations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
