Primary Outcome Measures:
  • The percentage of patients with a NRS of ≥ 4 during intervention (2.5 mg versus 7.5 mg morphine iv) [ Time Frame: The first intervention one day after admission ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • The mean NRS during an intervention (2.5 mg versus 7.5 mg morphine iv) [ Time Frame: 10 days ] [ Designated as safety issue: No ]
  • The percentage of patients with at least one NRS-score of ≥ 4 at rest during ICU stay [ Time Frame: 10 days ] [ Designated as safety issue: No ]
  • The mean NRS per patient in rest during ICU stay [ Time Frame: 10 days ] [ Designated as safety issue: No ]
  • The percentage of patients with a NRS of ≥ 6 during intervention (2.5 mg versus 7.5 mg morphine iv) [ Time Frame: one day after admission in the ICU ] [ Designated as safety issue: No ]
  • Pharmacokinetic parameters of morphine iv (volumes of distribution and clearance values) [ Time Frame: 10 days ] [ Designated as safety issue: No ]
  • Pharmacodynamic parameters of morphine iv (EC50 etc) [ Time Frame: 10 days ] [ Designated as safety issue: No ]
  • Covariates for the PK/PD of morphine iv [ Time Frame: 10 days ] [ Designated as safety issue: No ]
  • Safety and other measures of the analgesics (morphine iv and paracetamol) used for intervention related pain as well as pain titration protocol for pain control in rest. [ Time Frame: 10 days ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 150

Study Completion Date: February 2010
Primary Completion Date: February 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: A
patients receive 2,5 mg morphine iv, before the first intervention on the day after admission in the ICU
Drug: morphine
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

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.
