Abstract

AIM: To investigate whether the fluid volume administered during esophageal cancer surgery affects pulmonary gas exchange and tissue perfusion. ----- METHODS: An exploratory single-center randomized clinical trial was performed. Patients with esophageal cancer who underwent Lewis-Tanner procedure between June 2011 and August 2012 at the Department of Thoracic surgery "Jordanovac", Zagreb were analyzed. Patients were randomized (1:1) to receive a restrictive volume of intraoperative fluid (≤8 mL/kg/h) or a liberal volume (>8 mL/kg/h). Changes in oxygen partial pressure (Pao2), inspired oxygen fraction (FiO2), creatinine, and lactate were measured during and after surgery. ----- RESULTS: Overall 16 patients were randomized and they all were analyzed (restrictive group n=8, liberal group n=8). The baseline value Pao2/FiO2 ratio (restrictive) was 345.01±35.31 and the value six hours after extubation was 315.51±32.91; the baseline Pao2/FiO2 ratio (liberal) was 330.11±34.71 and the value six hours after extubation was 307.11±30.31. The baseline creatinine value (restrictive) was 91.91±12.67 and the value six hours after extubation was 100.88±18.33; the baseline creatinine value (liberal) was 90.88±14.99 and the value six hours after extubation was 93.51±16.37. The baseline lactate value (restrictive) was 3.93±1.33 and the value six hours after extubation was 2.69±0.91. The baseline lactate value (liberal) was 3.26±1.25 and the value six hours after extubation was 2.40±1.08. The two groups showed no significant differences in Pao2/FiO2 ratio (P=0.410), creatinine (P=0.410), or lactate (P=0.574). ----- CONCLUSIONS: Restriction of intraoperative applied volume does not significantly affect pulmonary exchange function or tissue perfusion in patients undergoing surgical treatment for esophageal cancer.

Abstract in Croatian

Intraoperacijska restrikcija volumena tekućine kod operacije karcinoma jednjaka: eksploratorno randomizirano kliničko istraživanje ----- Cilj: Istražiti utječe li volumen tekućine koji se daje za vrijeme operacije jednjaka na izmjenu plinova u plućima i perfuziju tkiva. ----- Postupci: Proveli smo unicentrično, randomizirano kliničko istraživanje. Istraživanje je uključilo pacijente s karcinomom jednjaka koji su podvrgnuti Lewis-Tannerovom postupku između lipnja 2011. i kolovoza 2012. na Klinici za torakalnu kirurgiju “Jordanovac,” u Zagrebu. Pacijenti su randomizirani (1:1) u skupinu koja je dobila restriktivni volumen intraoperativne tekućine (≤8 mL/kg/h) ili u skupinu koja je dobila slobodnu razinu volumena intraoperativne tekućine (>8 mL/kg/h). Mjerili smo promjene parcijalnog tlaka kisika (PaO2), udjela udahnutog kisika (FiO2), kreatinina i laktata za vrijeme i nakon operacije. ----- Rezultati: Uključeno je 16 pacijenata (restriktivna skupina, n = 8; skupina sa slobodnim volumenom, n = 8). Početna vrijednost omjera PaO2/FiO2 (restriktivna skupina) bila je 345,01 ± 35,31, dok je vrijednost 6 sati nakon ekstubacije bila 315,51 ± 32,91; početni PaO2/FiO2 omjer (skupina sa slobodnim volumenom) bio je 330,11 ± 34,71, dok je vrijednost 6 sati nakon ekstubacije bila 307,11 ± 30,31. Početna vrijednost kreatinina (restriktivna skupina) bila je 91,91 ± 12,67, dok je vrijednost 6 sati nakon ekstubacije bila 100,88 ± 18,33; početna vrijednost kreatinina (skupina sa slobodnim volumenom) bila je 90,88 ± 14,99, dok je vrijednost 6 sati nakon ekstubacije bila 93,51 ± 16,37. Početna vrijednost laktata (restriktivna skupina) bila je 3,93 ± 1,33, dok je vrijednost 6 sati nakon ekstubacije bila 2,69 ± 0,91. Početna vrijednost laktata (skupina sa slobodnim volumenom) bila je 3.26 ± 1.25, dok je vrijednost 6 sati nakon ekstubacije bila 2,40 ± 1,08. Nije bilo značajne razlike između skupina ni u PaO2/FiO2 omjeru (P = 0,410) ni u razinama kreatinina (P = 0,410) i laktata (P = 0,574). ----- Zaključak: Restrikcija intraoperativnog volumena tekućine ne utječe značajno ni na izmjenu plinova u plućima ni na perfuziju tkiva kod operacije karcinoma jednjaka.
