Pain During Chest Tube Withdrawal: Evaluation Using Pan Monitor
Pain During Chest Tube Withdrawal: Evaluation Using Pan Monitor
Pain evaluation remains a clinical problem. Pain Monitor allows pain evaluation using the
 measurement of skin conductance.

 Withdrawal of chest tube can be painful and the purpose of the study was to compare
 auto-evaluation of pain (visual analogic scale) and the index measured by the Pain Monitor.
Inclusion Criteria:

 -  patients undergoing removal of a chest tube after lung surgery,

 -  patients able to indicate the pain score.

 Exclusion Criteria:

 -  pregnancy, lactation ,

 -  insulin-dependent diabetes with dysautonomia,

 -  central or peripheral neurological disease, agitation,

 -  inability to understand the protocol,

 -  inability to use the Pain Monitor: skin abnormalities at the site of measurement,
 pacemaker or implantable defibrillator, condition affecting the sympathetic nervous
 system, tremor of the extremities,

 -  contra-indication to oral morphine ,

 -  respiratory failure, severe hepatic insufficiency, intracranial hypertension, epilepsy
