Objective: To review the effectiveness of intravenous tranexamic acid in reduction of blood loss, surgical time and field visualization among patients who underwent endoscopic sinus surgery (ESS) for chronic rhinosinusitis (CRS).  Methods: Data Sources:  MEDLINE (PubMed), EMBASE, ScienceDirect, HERDIN, and the Cochrane Library. Eligibility Criteria: Randomized controlled trials (RCT) between 2005-2014 that evaluated the effects of tranexamic acid or placebo in patients undergoing ESS for CRS. Appraisal and Synthesis Methods: Articles were selected by 2 independent reviewers and methodological quality was blindly evaluated using a Jadad scale. Data were compiled in tables for analysis of outcome measures (estimated blood loss, length of surgery and intraoperative surgical field visualization). Results: Two trials were included in the study, enrolling 128 patients. One arm of the study had been given tranexamic acid while the other arm was given placebo (saline solution). Results varied for both studies. The summary of the observed difference for blood loss had a standardized mean difference of -51.20 (CI95 [-59.44, -42.95]) showing that the blood loss in milliliters was less in the tranexamic group compared to saline solution. The summary of the observed difference in surgical time had a standardized mean difference of -19.32 (CI95 [-24.21, -14.43]) showing that the surgical time in minutes was shorter in the tranexamic group compared to saline solution. The secondary outcome on surgical field visualization was not pooled together because the studies used different measurement scales. Limitations:  The most important weaknesses of the 2 included studies were the differences in dose of tranexamic acid, scales of measurement of field visibility and age groups of the patients.  Conclusion: Tranexamic acid reduced blood loss and shortened surgical time after ESS among patients with CRS. However, the additional benefit of tranexamic acid for better field visualization was not clear. Adverse effects were not considered in this study, however results support the use of intravenous tranexamic acid intraoperatively as an option for ESS with blood loss as a concern. Further randomized clinical trials and an update on the systematic review will strengthen the evidence on the effectivity of tranexamic acid for ESS.

Background: Functional endoscopic sinus surgery (FESS) requires effective control of bleeding for better visibility of the operating field and reduced risk of injury to the optic nerve or the internal carotid artery. Controlled hypotension is a technique used to limit intraoperative blood loss to provide the best possible field for surgery. Objectives: Our study is undertaken to evaluate the efficacy of dexmedetomidine as a hypotensive agent in comparison to esmolol in Functional Endoscopic Sinus Surgery (FESS). Methods: Sixty (60) patients 20 – 50 years of age, ASA I/II scheduled for FESS were randomly assigned to two equal groups of 30 patients each. Patients of group D received dexmedetomidine 1µg/kg over 10 min before induction of anesthesia followed by 0.4 – 0.8 µg/kg/hr infusion during maintenance and group E received esmolol loading dose 1mg/kg was infused over one min followed by 0.4 – 0.8 mg/kg/hr infusion during maintenance to maintain mean arterial blood pressure (MAP) between (55 – 65 mmHg). The surgical field was assessed using Average Category Scale and average blood loss was calculated. Hemodynamic variables (MAP, HR); intraoperative fentanyl consumption and total recovery from anesthesia (Aldrete’s score ≥9) were recorded. Sedation score was determined at 10, 20, 30, 40 & 60 min after tracheal extubation and time to first analgesic demand was also recorded. Results:In both group D and group E reached the desired MAP (55–65 mmHg) with no inter group difference in MAP or HR. Mean intraoperative fentanyl consumption was significantly lower in group D than group E. Recovery time to achieved Aldrete’s score ≥9 were significantly lower in group E compared with group D.The sedation score were significantly lower in group E compared with group D at 10 minutes, 20 minutes and 30 minutes postoperatively. Time to first analgesic demand was significantly longer in group D. Conclusion: The result of this study showed that both dexmedetomidine and esmolol can be used as agents for controlled hypotension and are effective in providing ideal surgical field during FESS. But dexmedetomidine offers the advantage of inherent analgesic, sedative and anesthetic sparing effect. Bangladesh J Otorhinolaryngol; April 2018; 24(1): 37-49

Background and Objectives: The success of functional endoscopic sinus surgery (FESS) depends on the visual clarity of the surgical field, which is understudied. Controlled hypotension has many advantages for FESS including reduction in blood loss and improved quality of the surgical field. This study determined whether the use of β-blockers as a premedication could improve the operative field in FESS. Methods: Sixty patients aged from 18 to 50 years, undergoing septoplasty and FESS were included in this prospective, randomized, double-blind, placebo-controlled study. Patients were randomly assigned to receive either metoprolol (100 mg, group 1) or a placebo (a vitamin tablet, group 2) 60 min before surgery. Results: The average blood loss and surgery duration were not significantly higher in the placebo group. The surgical field was graded using the Fromme-Boezaart scale, and it was significantly clearer (p < 0.001) in metoprolol group. The mean arterial blood pressure was significantly lower in the metoprolol group after 30 min of induction until the end of surgery (p < 0.001). The heart rate was also significantly lower (p < 0.001) in those who received metoprolol from before induction of anesthesia up to the end of surgery. Conclusion: Metoprolol significantly improves visual clarity and hemodynamics during FESS. We would recommend the use of metoprolol in FESS and septoplasty.

Objectives: Topical vasoconstrictors and intravenous tranexamic acid (IV TXA) are safe and efficacious to decrease bleeding and improve the surgical field during endoscopic sinus surgery (ESS). The purpose of this study was to investigate practice patterns, awareness of clinical evidence, and comfort levels among anesthesia providers regarding these hemostatic agents for ESS. Methods: A total of 767 attending anesthesiologists, residents, and certified registered nurse anesthetists (CRNAs) at 5 United States academic centers were invited to participate in a survey regarding their experience with IV TXA and 3 topical vasoconstrictor medications (oxymetazoline, epinephrine, and cocaine) during ESS. Results: 330 (47%) anesthesia providers responded to the electronic survey. 113 (97%) residents, 92 (83%) CRNAs, and 52 (68%) attendings managed 5 or fewer ESS cases per month. Two-thirds of providers had not reviewed efficacy or safety literature for these hemostatic agents. Oxymetazoline was perceived safest, followed by epinephrine, IV TXA, and cocaine. Respondents considered potential side effects over surgical field visibility when selecting agents. The majority of providers had no formal training on these agents for ESS, but indicated interest in educational opportunities. Conclusion: Many anesthesia providers are unfamiliar with safety and efficacy literature regarding agents used to improve hemostasis for ESS, highlighting a need for development of relevant educational resources. Rhinologic surgeons have an opportunity to communicate with anesthesia colleagues on the use of hemostatic agents to improve the surgical field during ESS.
