ENGLISH SUMMARY
Introduction: Fasting is an important safety precaution for patients
before surgery but studies indicate that excessive fasting is common.
Explanations for this, including patient education related factors, are not
well known. The aim of this study was to explore how long patients fast
before surgery and what instructions they received, one year after the
introduction of new guidelines for patients and professionals.
Material and methods: This descriptive study was undertaken in a
national, 660-bed university hospital in 2011. Data was collected from
patient records and with questionnaires. Included were adult surgical
patients having anaesthesia during a 5day period.
Results: The sample consisted of 193 patients: 83% were scheduled
for elective surgery and 86% returned questionnaires. Average fasting
time was 13,6 (±3.0) hours for solid food and 8,8 (±4.5) hours for clear
fluids. A quarter (27%) had received instructions according to guidelines
and 45% were instructed to fast from midnight. Information was either
written (18%), verbal (37%) or both (45%) and 46% of patients received
information on the importance of fasting. Patients scheduled for morn-
ing surgery fasted for a shorter time than afternoon patients (p<0.05).
Patients who received both verbal and written information fasted shorter
on clear fluids (p<0.001) than others.
Conclusions: The fasting of surgical patients before their operation
is unnecessarily long and they do not get uniform instructions. This
warrants further exploration. There is a need for staff to coordinate
instructional practices, to involve patients more in their own care with
consistent information and comprehensive education and assist them in
reducing fasting on clear fluids after hospital admission.

gefa þeim kolvetnaríka drykki þar til tveir tímar eru til aðgerðar.
Áhugavert væri að fylgja þessari rannsókn eftir með því að kanna
hvaða leiðbeiningar sjúklingar fá í dag, hversu mikið seinkun á
aðgerðaráætlun skýrir langa föstu og hvaða skýringar sjúklingar
gefa varðandi lengd föstunnar.
Þakkir
Sjúklingum sem tóku þátt í þessari rannsókn eru færðar bestu
þakkir svo og starfsfólki skurðlækningasviðs Landspítala sem
aðstoðaði við gagnasöfnun, og Jeannette T. Crenshaw sem veitti
ráðgjöf við gerð spurningalistans.
