Abstract [sv]

Gällande riktlinjer för preoperativ fasta beskriver att patienter med liten risk för aspiration kan inta fast föda fram till sex timmar och klara drycker fram till två timmar före start av anestesi. Studier har visat att många patienter fastar längre, vilket kan ha negativ inverkan både fysiologiskt och på välbefinnandet som till exempel dehydrering, törst, illamående, huvudvärk och nedsatt insulinkänslighet. Syftet med studien var att kartlägga och beskriva preoperativa fastetider, dryckintag samt förekomst av törst hos patienter planerade för elektiv kirurgi. Strukturerade intervjuer genomfördes under fem dagar med 50 patienter som rekryterades konsekutivt på två preoperativa avdelningar. Resultaten visade att majoriteten av patienterna instruerats att inta klara drycker fram till två timmar före start av anestesi. Fastetider hos patienter med strikt fasta varierade mellan 7,75 till 13,25 timmar (median 10 och dryckintag mellan 0,5 till 7,5 glas (medelvärde 3,14; standardavvikelse 1,98). Fastetider hos patienter med flytande fasta varierade mellan 0,75 till 11,25 timmar (median 3,5 och dryckintag mellan 1 till 9 glas (medelvärde 4,31; standardavvikelse 1,91). Av de 50 intervjuade patienterna uppgav 44 % att de upplevde törst. Studiens resultat visade på en stor variation i fastetider och dryckintag där de äldsta patienterna tenderade att fasta länge och inta små mängder dryck preoperativt.

Abstract [en]

Existing guidelines for preoperative fasting means that patients with a minimal risk of aspiration can take solid food until six hours, and clear drinks until two hours before start of anesthesia. Studies have shown that many patients are fasting longer, which may be detrimental both physiologically and on wellbeing, for example, dehydration, thirst, nausea, headache and reduced insulin sensitivity. The purpose of this study was to map and describe fasting times, beverage intake and the incidence of thirst preoperatively in patients who were undergoing elective surgery. Structured interviews were conducted over five days with 50 patients who were enrolled consecutively in two preoperative departments. The results showed that fasting times in patients with strict fasting ranged from 7.75 to 13.25 hours (MD 10) and beverage intake between 0.5 to 7.5 glasses (3.14 SD 1,98). Fasting times in patients with float fasting ranged from 0.75 to 11.25 hours (MD 3,5) and beverage intake between 1 to 9 glasses (4,31 SD 1,91). Of the 50 interviewed patients, 44 % said they experienced thirst. The results indicated a wide variation in preoperative fasting times and beverage intake, where the oldest patients tended to have long duration of fasting and intake of small amounts of beverage preoperatively.
