Randomized Controlled Trial Comparative StudyBlood loss during endoscopic sinus surgery with propofol or sevoflurane: a randomized clinical trial.
Total intravenous anesthesia (TIVA) with propofol has been associated with reduced operative time, decreased perioperative risks, and decreased intraoperative blood loss compared with inhalational anesthesia (IA). During endoscopic sinus surgery (ESS), reduced bleeding from the mucosal surfaces could improve visualization of the anatomy and decrease the risk of serious complications. ⋯ In this comparative study, our results did not show any difference in blood loss and surgical conditions between the TIVA and IA groups. Even further study is not likely to show a difference in blood loss between TIVA and IA during ESS.

Review Meta AnalysisSystematic review and meta-analysis of total intravenous anesthesia and endoscopic sinus surgery.
Total intravenous anesthesia (TIVA) has been shown in some studies to impact visual field, blood loss, and cardiovascular parameters during endoscopic sinus surgery when compared to inhalational anesthesia (IA). These variables are critical in endoscopic sinus surgery. A systematic review and meta-analysis was undertaken to discern the impact of TIVA vs IA in endoscopic sinus surgery. ⋯ Current evidence supporting TIVA is limited to a handful of inconsistently controlled and reported studies. Standardized grading of visibility scores and preoperative characteristics would better establish the role of TIVA in endoscopic sinus surgery.

Randomized Controlled Trial Comparative StudyEffects of three different types of anaesthesia on perioperative bleeding control in functional endoscopic sinus surgery.
The aim of the study was to assess the effect of three different types of anaesthesia on perioperative bleeding control and to analyse the mean arterial blood pressure and heart rate in patients undergoing endoscopic paranasal sinus surgery. Ninety patients (30 women and 60 men, aged 18-85 years) scheduled to undergo functional endoscopic sinus surgery in the years 2008-2010 were identified as candidates for inclusion in the study. Patients were randomly assigned to one of three groups (30 patients each) according to the type of general anaesthesia to be administered. ⋯ Mean anaesthesia duration in groups I, II and III was 108.7 ± 20.8, 112.6 ± 22.2 and 103.7 ± 17.5 min and the surgery duration was 71.3 ± 16.7, 78.8 ± 24.2 and 66.5 ± 15.5 min, respectively. Mean blood loss during surgery was 365.0 ± 176.2, 340.0 ± 150.5 and 225.0 ± 91.7 ml, with a mean blood loss rate of 5.1 ± 2.4, 4.5 ± 2.2 and 3.4 ± 1.1 ml/min in groups I, II and III, respectively. Technologically advanced control of the drug dose with the TIVA technique allows for better control of perioperative bleeding.

Induced controlled hypotension is a standard method aimed at decreasing intraoperative bleeding and achieving good operative field conditions. Low hemodynamic parameters during the operation are related to increased risk of brain hypoperfusion and injury to hypoxia-sensitive nerve cells. The purpose of this study was to find the mean arterial pressure (MAP) that preserves good operative conditions at low heart rate (HR) during endoscopic sinus surgery. ⋯ With the stable low heart rate at the minimal physiological values the bleeding in the operative field depends on MAP. Keeping HR around 60 b/min there is no need to decrease the MAP to dangerously low levels to achieve good operative field conditions in great proportion of patients.

Randomized Controlled Trial Comparative StudySurgical conditions during FESS; comparison of dexmedetomidine and remifentanil.
To compare dexmedetomidine with remifentanil in functional endoscopic sinus surgery (FESS) in regards to intra-operative bleeding, anesthetic consumption and post-operative recovery. Randomized, double blind study. Tertiary care medical center. ⋯ There was no significant difference between groups according to the amount of bleeding during surgery, assessment of surgical field condition, consumption of sevoflurane, scores of postoperative VAS, rates of nausea and vomiting, shivering, demands of additional analgesic medication (P > 0.05). The time to reach Aldrete recovery score 9-10, sedation scores at the postoperative first hour were significantly higher in group D (P = 0.001). We concluded that in comparison to remifentanil, dexmedetomidine during FESS for controlled hypotension is of limited value as it has no additional benefits in terms of control of hypotension and amount of bleeding in the surgical field and it is associated with higher recovery time and first-hour postoperative sedation scores.

Comparison of surgical conditions following premedication with oral clonidine versus oral diazepam for endoscopic sinus surgery: A randomized, double-blinded study.
Endoscopic sinus surgery (ESS) provides a challenge and an opportunity to the anesthesiologists to prove their mettle and give the surgeons a surgical field which can make their delicate surgery safer,more precise and faster. The aim of the study was to evaluate the surgical field and the rate of blood loss in patients premedicated with oral clonidine versus oral diazepam for endoscopic sinus surgery. ⋯ Premedication with clonidine as compared to diazepam, provides a better surgical field with less blood loss in patients undergoing ESS.

ReviewQuality of surgical field during endoscopic sinus surgery: a systematic literature review of the effect of total intravenous compared to inhalational anesthesia.
Adequate surgical field visualization is imperative for successful outcomes in endoscopic sinus surgery (ESS). The type of anesthetic administered can alter a patient's hemodynamics and impact endoscopic visualization during surgery. We review the current evidence regarding the effect of total intravenous anesthesia (TIVA) compared to inhalational anesthesia (INA) on visualization of the surgical field during ESS. ⋯ Although several studies reported that TIVA improves surgical conditions in ESS, there are significant limitations. These findings prevent any definite recommendation at this point, emphasizing the need for further high-quality studies.

Review Meta AnalysisMeta-analysis and literature review of techniques to achieve hemostasis in endoscopic sinus surgery.
Functional endoscopic sinus surgery (FESS) has been used as the standard of treatment for sinonasal disease in which medical therapy fails to ameliorate the disease. Intraoperative hemostasis is a crucial factor in FESS. Currently, ideal techniques for creating intraoperative hemostasis have yet to be clarified and standardized. We sought to better understand what variables can affect intraoperative blood loss and therefore improve surgical field outcomes. ⋯ Meta-analysis of 1148 patients concludes that hemostasis during FESS is best conducted using TIVA, preoperative steroids, and topical local anesthetic at a 1:200,000 concentration.

Endoscopic sinus surgery is commonly performed and has a low risk of major complications. Intraoperative bleeding impairs surgical conditions and increases the risk of complications. Remifentanil appears to produce better surgical conditions than other opioid analgesics, and total intravenous anaesthesia with propofol may provide superior conditions to a volatile-based technique. ⋯ The use of a laryngeal mask may be associated with improved surgical conditions and a smoother emergence. It provides airway protection equivalent to that provided by an endotracheal tube in well-selected patients, but offers less protection from gastric regurgitation. Post-operatively, multimodal oral analgesia provides good pain relief, while long-acting local anaesthetics have been shown not to improve analgesia.
