Clinical Trial Summary

The main objective of the trial is to investigate the effect of known genetic variants in organic cation transporter 1 (OCT1) on the effect of morphine after major surgery


Description:

The purpose of the experiment is to investigate the effect of known genetic variants in organic cation transporter 1 (OCT1) on the effect of morphine after major surgery. This is primarily done by investigating systemic exposure of morphine in a cohort of patients undergoing scheduled laparoscopic colon or laparoscopic rectum surgery, and as pain treatment with intravenous (iv) morphine at the end of and after surgery (primary endpoints). As a secondary endpoint, we will investigate the effect (pharmacodynamics) of morphine in the same patients by registering pain during rest and activity, side effects and the degree of sedation at appropriate time intervals.

Intervention

Drug:
Morphine
The study was designed as an open, non-controlled drug trial, with scientists and participants blinded to the patients OCT1 status. Morphine will be given as a single dosis (0,15 mg/kg) at the end of the Surgery and later as boluses of 0,04mg/kg administrated by patient-controlled analgesia, (PCA). Blood samples with drug concentrations will be used to determine a difference in morphine AUC due to the patients OCT1 status. Questionnaire answers will be used to determine the effect of morphine due to the patients OCT1 status

Outcome

Type Measure Description Time frame Safety issue
Primary Morphine Area under the curve (AUC) Difference in morphine AUC due to patient OCT1 status Blood samples will be drawn at zero, five, 10, 15, 30, 45, 60 and 90 minutes after the first morphine bolus
Secondary Morphine effect Pain during rest and activity will be evaluated through a Numeric Rating Scale on the same patients where 0 is no pain and 10 is the the worst possible pain. Questionnaire answers will be collected with an appropriate time interval for 24 hours after the first morphine bolus
Secondary Morphine effect side effects will be evaluated through a 5-point verbal questionnaire on the same patients where 0 is no side effects and 4 is unacceptable side effects. Questionnaire answers will be collected with an appropriate time interval for 24 hours after the first morphine bolus
Secondary Morphine effect The degree of sedation will be evaluated through the Richmond Agitation and Sedation Scale (RASS) on the same patients Questionnaire answers will be collected with an appropriate time interval for 24 hours after the first morphine bolus
Secondary Morphine effect The total dose of morphine used during the investigation. After the trial has ended (24 hours after the first morphine bolus) data containing morphine use will be collected.
Secondary Morphine effect The number of administrations of morphine will be recorded After the trial has ended (24 hours after the first morphine bolus) data containing morphine use will be collected.
