Ethyl Chloride Spray Versus Subcutaneous Lidocaine Anaesthetic Prior to Contraceptive Implant Insertion
Ethyl Chloride Spray Versus Subcutaneous Lidocaine Anaesthetic Prior to Contraceptive Implant Insertion
Study to look at the acceptability of local anaesthetic spray versus injection, prior to
 contraceptive implant insertion
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.
