A small tuft often overturns a big load : Bacterial contamination over time on surgical instruments used in open neurosurgery (English)
Abstract [sv]

Bakgrund: Postoperativa sårinfektioner orsakar lidande för den drabbade patienten och kostnader för patienten, vården och samhället. Intraoperativ kontamination av operationsinstrumenten är en av källorna till dessa infektioner. Operationssjuksköterskan är ansvarig för aseptiken och operationsinstrumenten.  

Syfte: Syftet med denna pilotstudie var att mäta graden av bakteriell kontamination över tid på operationsinstrument som används vid öppen neurokirurgi samt observera utvalda källor till kontamination under samma tid.

Metod: Denna studie designades som en kvantitativ icke-experimentell observationsstudie. Datainsamlingen skedde under hösten 2015 och bestod av omhändertagandet av specifika instrument som använts av operatören under operationen efter förutbestämd åtgången knivtid. Bakterieodlingar på dessa instrument skedde sedan på laboratorium enligt en förutbestämd metod och graden av kontamination mättes genom observation av mängden colony forming units (CFU). Resultaten presenteras i form av förändringar av mängden CFU.

Resultat: Fem operationer observerades och tio odlingar utfördes på tio instrument. Totalt tio CFU registrerades under samtliga observationer. Ingen signifikant ökning av antal CFU kunde observeras från en till två timmars knivtid (P=0,156). Antal dörröppningar ökade från 3,4 till 9,0 och antal personer på operationssalen ökade från 5,4 till 5,8.

Slutsats: Trots det ringa antal observationer som ingick i denna studie tyder resultaten på god aseptik och minimal bakteriell kontamination på operationsinstrumenten under operationens två första timmar. Ytterligare forskning med längre observationer, fler observationer och observationer kring annan typ av kirurgi behövs.

Abstract [en]

Background: Post-operative surgical site infections (SSI) cause suffering for the afflicted patient and is a great cost for the patient, the health care system and society. Intra-operative contamination of surgical instruments is one of the sources of these infections. The operating room nurse is responsible for preventing infections.

Purpose: The purpose of this pilot-study was to measure the degree of bacterial contamination over time on surgical instruments used in open neurosurgery as well as to observe specific sources of contamination during this time.

Method: The design was a quantitative nonexperimental observational study. The data collection took place during autumn 2015 and consisted of the sampling of specific instruments used by the surgeon during surgery after preset elapsed operating times. Bacterial culturing on these instruments was then carried out at a laboratory according to a preset routine and the degree of contamination was measured by observing the amount of colony forming units (CFU). The results are presented as changes in CFU.

Results: Five operations were observed and ten bacterial culturings were conducted on ten instruments. A total of ten CFU was registered during all observations. No significant increase in the number of CFU could be observed from one to two hours of elapsed surgery (P=0,156). The amount of door openings increased from 3,4 to 9,0 and the number of personnel in the operating room increased from 5,4 to 5,8.

Conclusion: Despite the small number of observations included in this study the results indicate good aseptics and minimal bacterial contamination on the surgical instruments during the first two hours of surgery. Further research with longer observations, more observations and observations on other forms of surgery is needed.
