Intrauterine lignocaine as an anaesthetic during endometrial sampling: a randomised double-blind controlled trial
1Department of Obstetrics and Gynaecology, Princess Margaret Hospital, Hong Kong, China.
Objective:
To evaluate the effectiveness of intrauterine lignocaine as an anaesthetic during endometrial sampling.
Design:
Prospective, randomised, double-blind, placebo-controlled trial.
Setting:
Outpatient gynaecological minor operation unit in a public hospital.
Population:
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.
Main Outcome Measures:
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.
Conclusions:
Transcervical instillation of lignocaine reduced pain during endometrial sampling.

Local Anesthetics: Clinical Application as Epidural Anesthesia
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...
