comparison of surgical conditions during propofol or isoflurane anesthesia for endoscopic sinus surgery

چکیده
background the anesthesia planning is an important and determining factor in the amount of intraoperative hemorrhage, which can affect the rate of intraoperative and postoperative complications. objectives in this study we used two different anesthesia techniques in functional endoscopic sinus surgery (fess) and compared the amount of hemorrhage in the two groups. patients and methods in a single–blind clinical trial, 44 patients with asa class i and ii candidate for fess in amir-al-momenin hospital in rasht were entered the study and divided into two equal groups randomly. in both groups anesthesia was induced with propofol, remifentanil and cis. atracurium and then, infusion of propofol – remifentanil in the first group and isoflurane plus remifentanil infusion in the second group was used for maintenance of anesthesia. systolic blood pressure was maintained about 90 mmhg. then on the basis of maximum allowable blood loss (mabl) formula, we calculated the percentage of hemorrhage. finally the patients' hemorrhage was categorized into three groups (< 10%, 10-20%, > 20%). the surgeon's satisfaction from surgical field was calculated according to the visual analogue scale. then the data was statistically analyzed with t- test. results there were meaningful differences between average of hemorrhage (propofol group = 155cc, and isoflurane group = 291.3cc; p = 0.003), and surgeon’s satisfaction (propofol group = 1.9 and isoflurane group = 2.95; p = 0.007). conclusions the amount of hemorrhage in propofol group was less than isoflurane group and the field condition was better in propofol group than the isoflurane group.

BACKGROUND Reduction of intraoperative bleeding is necessary to achieve the ideal surgical field for the endoscopic sinus surgery (ESS). Intraoperative intra nasal bleeding is influenced by various anesthetics. This study compared surgical field condition between propofol/remifentanil (PR) based anesthesia and desflurane/remifentanil (DR) based anesthesia. METHODS American Society of Anesthes...

BACKGROUND Endoscopic sinus surgery (ESS) is often affected by intra-nasal bleeding, which can be influenced by various anaesthetics and preoperative conditions. This study compared the surgical condition and the amount of intra-nasal bleeding between patients given sevoflurane/remifentanil (SR) and propofol/remifentanil (PR) anaesthesia. METHODS ASA I or II patients undergoing ESS were rando...

Comparison of surgical condition in endoscopic sinus surgery using remifentanil combined with propofol, sevoflurane, or desflurane
BACKGROUND Various maneuvers are commonly used to achieve the ideal operative field necessary for successful endoscopic sinus surgery (ESS). There are a few contradictory reports on this subject and the consensus is that propofol anesthesia results in a better or similar surgical field and less or similar amount of bleeding than volatile anesthesia. The aim of this study was to compare the surg...

BACKGROUND In sheep, isoflurane causes extravascular accumulation of infused crystalloid fluid. The current study evaluates whether isoflurane has a greater tendency than propofol to cause extravascular retention in surgical patients. METHODS Thirty patients undergoing thyroid surgery lasting for 143 +/- 32 min (mean +/- SD) received an intravenous infusion of 25 ml/kg acetated Ringer's solut...
