BACKGROUND This study was designed to compare differences in intraoperative blood loss, mean arterial blood pressure (MABP), and duration of surgery when 0.25% bupivacaine with 1:200000 epinephrine is injected, preoperatively, versus normal saline (NS), during functional endoscopic sinus surgery (FESS). METHODS A prospective, double-blind randomized placebo-controlled study was performed. Par...

Objective. We aimed to investigate the effect of peritubal local anesthetic and opioid infiltration on pain scores and analgesic consumption in patients who underwent percutaneous nephrolithotomy. Material and Methods. Patients aged between 18 and 65 years and ASA I-III were included in this double-blind, randomized study. The patients were divided into two groups. All patients underwent spinoe...

Background: Postoperative pain is an important surgical problem. Recent studies in pain pathophysiology have led to the hypothesis that with perioperative administration of analgesics (pre-emptive analgesia) it may be possible to prevent or reduce postoperative pain. This study was planned to investigate the efficacy of pre-emptive analgesia on postoperative pain after major gynecologic abdomin...

OBJECTIVE Perioperative analgesia effects the postoperative course of pain. The purpose of this study was to evaluate its possible relation with the consumption of dolantine and analgesics and the facet-induced pain and postoperative pain score in degenerative disc surgery. METHODS We employed perioperative intra- and perifacet bupivacaine infiltration technique to reduce the postoperative pa...

Background: There are different anesthetic techniques for AVF (Arterio-venous fistula) creation as general anesthesia, regional anesthesia and local anesthetic infiltration. Sympathetic nerve block is produced by regional anesthesia which increases intraoperative venous diameter and vessel flow, both intra-operatively and for several hours post-operatively. Regional anesthesia can maintain adeq...
