Abstract
Ensuring adequate fluid therapy
in the perioperative period have a significant role on meeting the increased
metabolic requirements and the prevention of postoperative complications. In
general fluid treatment methods called as restrictive or liberal have been implemented
for maintaining fluid balance in the perioperative period. These methods are
based on calculation of the known or estimated fluid loss. In recent researches
have shown that implemented fluid
therapy according to these methods may be excessive or insufficient and may cause problems like fluid loading and
hypovolemia. Today to avoid all these
problems, individual goal directed fluid therapy is recommended in
perioperative period. In individual goal directed fluid therapy amount and type
of fluid to be applied have been selected cosidering
individual characteristics of patients and treatment have been implemented
under the guidance of determined hemodynamic criteria. In this article,
information concerning the implemented fluid treatment methods for surgical
patients in the perioperative period is presented.

Abstract
Ameliyat sürecini kapsayan dönemde uygun sıvı
tedavisinin sağlanması, artan metabolik gereksinimlerin karşılanması ve
ameliyat sonrası dönemde komplikasyonların önlenmesinde önemli role sahiptir.
Genel olarak ameliyat sürecinde sıvı dengesinin sürdürülebilmesi için serbest
ya da kısıtlayıcı olarak adlandırılan sıvı tedavisi yöntemleri uygulanmaktadır.
Bu yöntemler, bilinen ya da tahmin edilen sıvı kayıplarının hesaplanması ve
karşılanması esasına dayanmaktadır. Son yıllarda yapılan çalışmalar, bu
yöntemlere göre uygulanan sıvı tedavilerinin aşırı ya da yetersiz olabildiğini
ve sıvı yüklemesi ya da hipovolemi gibi sorunlara neden olabildiğini göstermektedir.
Günümüzde tüm bu sorunların önlenebilmesi için ameliyat sürecini kapsayan
dönemde bireye özgü hedefe yönelik sıvı tedavisi önerilmektedir. Bireye özgü
hedefe yönelik sıvı tedavisinde uygulanacak sıvının miktarı ve cinsi hastaların
bireysel özellikleri dikkate alınarak seçilmekte ve tedavi belirlenen hemodinamik
ölçütlerin rehberliğinde uygulanmaktadır. Bu makalede, ameliyat sürecini
kapsayan dönemde uygulanan sıvı tedavisi yöntemlerine ilişkin bilgi
sunulmaktadır
