Assessment of Anxiety in Patients Treated by SMUR Toulouse and Receiving MEOPA as Part of Their Care

• Conditions: Pain; Anxiety

• Registration Number: NCT03613155
• Lead Sponsor: University Hospital, Toulouse

Brief Summary

The emergency setting, frequently associated with pain and the feeling of loss of control, can cause anxiety in patients.

Reaction anxiety may be an appropriate response to an emergency; Nevertheless, attention must be paid to the evaluation and management of the latter especially as anxiety and pain are closely linked.

Detailed Description

There is a definite interest in the management of patients' pre-hospital anxiety. The literature reports a strong association between anxiety, post-traumatic stress and chronic pain. A study conducted at SAMU 31 also found that anxiety on arrival at the emergency department was a negative factor in the treatment of pain. Anxiety can reduce the pain threshold and promote hyperalgesia.

The management of patient anxiety in pre-hospital offers interesting results in terms of analgesia and satisfaction of users of care and should not be neglected.

MEOPA has recently been available in SMUR vehicles (emergency and resuscitation mobile service) at SAMU 31 (urgent medical assistance service); its availability can lead teams to change their practices. More and more emphasis is placed on the importance of positive communication and comfort for which MEOPA, with its conscious sedating effect, could be a facilitating factor.

The aim of our study is to evaluate the level of anxiety of patients treated by SMUR teams in Toulouse and receiving MEOPA following the usual indications for pain-induced pain or pain alleviation.

This is a pilot study, which focuses on the assessment of anxiety in patients treated in pre-hospital care by SMUR Toulouse and receiving MEOPA as part of their care. No data exists in the literature on this subject.

This descriptive study based on qualitative data collected by the FAS1 scale will provide us with the first data on this population. It does not change the usual management of the patient since only patients who must receive MEOPA following the usual indications for pain relief or pain-induced care will be included in the study

Primary Outcome Measures

Name	Time	Method
The state of anxiety of the patient assessed by Face Anxiety Scale	2 hours	The state of anxiety of the patient assessed by FAS (face anxiety scale) self-assessment when supported by a SMUR team with MEOPA administration.; The FAS, called the Anxiety Faces Scale, is a validated anxiety assessment scale that was originally developed in the context of Critical Care, Critical Care (ICU) management.; The Faces Anxiety Scale is a valid single-item, self-report measure of state anxiety in intensive care patients that is easy to administer and imposes minimal respondent burden. It has the potential to be a useful instrument for the assessment of state anxiety by clinicians and for research into the reduction of anxiety in this vulnerable population.

Secondary Outcome Measures

Name	Time	Method
The pain felt by the patient, evaluated by the numerical scale (EN), in connection with his anxiety	2 hours	EN is a self-rated scale of pain: the patient rates his or her pain on a numeric scale from 0 (no pain) to 10 (maximum pain). The evaluation of the pain at the SAMU is carried out in routine at each support by the EN. For the purposes of this study, the investigators will find the value of the EN in the same temporality as the assessment of anxiety.
