Ethyl Chloride Spray Versus Subcutaneous Lidocaine Anaesthetic Prior to Contraceptive Implant Insertion

Withdrawn

• Conditions: Contraception

• Registration Number: NCT02651207
• Lead Sponsor: Tayside Medical Science Centre

Brief Summary

Study to look at the acceptability of local anaesthetic spray versus injection, prior to contraceptive implant insertion

Detailed Description

Currently, patients undergoing contraceptive implant insertion are offered local anaesthetic with an injection before insertion. This study aims to look at whether patients find using the local anaesthetic spray more acceptable or equally acceptable to using local anaesthetic injection. Both are currently licensed products for use as skin anaesthesia but the spray is potentially quicker and involves less injections. Some areas of sexual health are already offering this option but there isn't much evidence as to which patients find more acceptable.

Patients in this study will be given a choice of anaesthetic asked to complete a short questionnaire, giving a pain score , on the pain rating scale of 0 to 10, ( being no pain to 10 being extremely painful. ) In addition, they will be asked to give the reasons for their choice. The questionnaire will be anonymous.

Average pain scores will be calculated between in group and compared.
