Opioid-inducerad obstipation i samband med postoperativ smärtbehandling : Förekomst och förebyggande åtgärder
Objective: The objective was to examine the incidence of constipation, and the preventive measures taken in relation with postoperative pain treatment with opioids at two orthopaedic surgery wards.
Methods: The participants were patients that had undergone surgery in the back, hip or thigh. They were selected through systematic selection and a total of 46 electronic health records were examined. The factors investigated and tested for correlation with constipation were the usage of laxatives, daily fluid-intake and early mobilisation.
Results: Totally, 26.1 % of the patients became constipated, and laxatives were prescribed to 65.2 % of the patients. Doctors prescribed 53.3 % of the laxatives, nurses 33.3 % and for the remaining 13.3 % it was uncertain who had written the prescription. Usage of laxatives seemed to cause constipation (p=0,025), whereas there was no correlation between constipation and early mobilization. The documentation regarding daily fluid-intake was insufficient and no correlation test could be performed.
Conclusions: This study failed to demonstrate that usage of laxatives and early mobilization prevents constipation in patients postoperatively treated with opioids. There was a need for increased education about constipation and its preventing measures for health care workers.
