About
Bronchoscopy is an examination performed routinely in pulmonology. This exam is considered as uncomfortable by nearly 60% of patients, especially due to respiratory blocking sensation, cough and nausea it causes, despite the use of a local anesthetic. Conversely, this examination is rarely performed under general anesthesia in hospitals in France, because it lengthens the duration of the procedure, increases its cost and can be dangerous for the respiratory failure patient.
Hypnosis is an altered state of consciousness between wakefulness and sleep, which can cause the patient to ignore the reality in which he is focusing his attention on his imagination, reducing his anxiety, his painful or unpleasant perceptions and their memorization.
The hypnosis benefit has already been evaluated in the control of pain and anxiety in many medical situations, surgical, obstetric and dental. In endoscopy, the results are mixed. In bronchoscopy, hypnosis has, to our knowledge, not been evaluated.
In a preliminary study in the endoscopy unit of the Hospital Saint Joseph, involving 66 patients, investigators showed that bronchoscopy was poorly tolerated in more than half of patients and that this poor tolerance was correlated to the level anxiety of patients, but 75% of patients surveyed would prefer the waning redo the examination in the same conditions if their health required it, rather than using a general anesthetic. Investigators then hypothesized that hypnosis would improve tolerance bronchoscopy under local anesthesia, without the need for general anesthesia.
Full description
Primary objective:
To compare the safety of bronchoscopy performed under local anesthesia and hypnosis to that performed under local anesthesia alone.
Secondary objectives:
Development of the study:
If the eligibility criteria are present, it will be proposed to the patient to participate in a study to assess the tolerance of Examination under hypnosis. A fact sheet will be handed to him explaining the purpose of the study and the place of examination. If he agrees to participate, consent will be obtained in writing and will be randomized into one of two groups. He will fill a questionnaire clinical information and Anxiety Questionnaire HAD (Hospital Anxiety and Depression Scale). The examination is then conducted in endoscopy room. In the hypnosis group, the patient will benefit from an induction technique of hypnosis by a doctor trained in hypnosis and local anesthesia performed by the endoscopist. In the control group, only local anesthesia is practiced by the endoscopist. The waning, it will ask the patient and endoscopist to complete an evaluation of the tolerance of the examination questionnaire.
Methodology :
DESIGN:
Number of subjects required: 126
The prevalence of poor tolerance of the examination in this population was 52% (numeric scale of the overall tolerance> 3) and the expected objective in the intervention group under hypnosis is a halving of the number of patients with EN > 3 to the overall safety, the number of subjects to be included is 63 per group.
Time study: baseline in January 2015 for an expected period of eight months depending on the pace of inclusion estimated to average 4 per week.
Randomization:
Randomization in the 2 groups will be made by day of the week carries the hypnotherapist (Monday or Tuesday with a random alternation between these 2 days). The list of days will be balanced by randomly alternating blocks. The team of bronchoscopy and prescribers of the bronchoscopy will not be informed of the first schedule to avoid selection bias of patients.
Acquisition of data:
Statistical analysis:
To find and test differences, univariate analyzes will use the test t-Student for continuous variables and the chi of 2 for categorical variables or their nonparametric equivalents. The significance level was set at p <0.05.
1.2 Serious Adverse Event (SAE)
A serious event is an event:
The term "life-threatening" is reserved for immediate life-threatening at the time of the adverse event, regardless of the consequences of corrective or palliative therapy.
Certain circumstances requiring hospitalization are not within the gravity standard "inpatient / hospitalization extension" as:
admission for social or administrative reasons; hospitalization predefined by the protocol; hospitalization for medical or surgical treatment scheduled prior research; passing day hospital.
All adverse events should be investigated, reported and recorded, processed and evaluated the first visit (inclusion Day 0) until the end of the study until their resolution.
Adverse events are collected:
All adverse events will be recorded on forms on adverse events of case report form (see Appendix 6). Each observed adverse events will be recorded individually. The intensity of adverse events will be determined as follows:
2.1 Statement of SAEs
The investigator evaluates each adverse event in relation to its severity. The investigator must notify by fax (01 44 12 32 52) to the sponsor (CRC GHPSJ) without delay after the day he heard, all serious adverse events in the trial, except from those identified in the protocol as not requiring immediate reporting. This initial notification is the subject of a written report must be followed if necessary by one or the report (s) Additional (s) writing (s) Main (s) within 8 days of the first declaration.
The investigator must document the best event (thanks to copies of laboratory results or reports of examinations or hospitalization accounts informing the serious event, including relevant negative results, not forgetting to make these documents and anonymous to register number and the patient's code), medical diagnosis and a causal link between serious adverse events and research.
The statement is sent to the developer with the serious adverse event reporting form signed and dated.
The investigator should follow the patient with an SAE to its resolution, stabilization at a level deemed acceptable by the investigator or return to the previous state, even if the patient is out of the test and inform the promoter (CRC GHPSJ) fax: 01 44 12 32 52 using the form (check: monitoring).
2.2 Assessment of causality
The investigator should assess causality of adverse events with research. The causal link is binary (connected / not connected).
2.3 Reporting period and followed the terms of adverse events
The investigator should report serious adverse events from the inclusion of the patient until the end of the experimental procedure.
The investigator should monitor adverse events until resolution or stabilization even if the patient is out of the study.
2.4 Special Cases
2.4.1 Serious Events not immediately declare
To the extent it is expected no serious adverse event related to the participation of patients in this study and that only certain serious adverse events known to be associated with bronchoscopy (hemoptysis, asthma, respiratory distress, allergic xylocaine etc.) may occur, they do not require immediate notification in accordance with the health authorities.
The Promoter will declare to ANSM and the CPP in accordance with the law of 9 August 2004:
all unexpected serious adverse reactions without delay and at the latest within seven calendar days from the day when the sponsor becomes aware of, and within 7 days for monitoring,
developments without delay safety and at the latest within 7 calendar days, and within 7 days for monitoring,
annual safety reports within 60 calendar days of the anniversary date of the study.
To the extent it is expected no serious adverse event related to the participation of patients in this study, Investigators do not want to establish an independent monitoring committee.
