Brief summary
The purpose of this study is to determine the influence of morphine 2,5 mg or morphine 7,5 mg iv during a painful and unavoidable intervention in critically ill patients.
Detailed description
In 2006, in the Intensive Care Unit (ICU) of the St. Antonius Hospital an analgesia improvement program has been implemented. This program consisted of training of ICU nurses and intensivists using a hospital based standardized pain protocol, and systematic pain measurements in rest, rated by the patient himself whenever possible or otherwise by the attending nurse. This program has resulted in a reduction of severe pain levels (NRS≥4) in ICU patients in rest from 41% to 22%. In order to further reduce this percentage, a pain titration protocol is introduced in 2007. As no attention has yet been paid to intervention-related pain levels in these patients, in this prospective study pain control will be studied using different analgesic dosages of morphine iv (2,5 mg vs 7,5 mg) around unavoidable painful interventions within a pain titration protocol for pain control in rest.
Interventions
patients receive 7,5 mg morphine iv 30 minutes before intervention (turning of the patient), the day after admission in the ICU. before, during and after, the patient will be asked to rate the pain using the NRS
