Abstract
Introduction The present study was conducted to compare the effects of clonidine and tranexamic acid on the volume of bleeding and quality of the surgical field in terms of bleeding in candidates who underwent rhinoplasty. Methods In this two-sided clinical trial, candidates eligible for rhinoplasty were randomly assigned to two treatment groups: tranexamic acid and clonidine. The first group received tranexamic acid at a dose of 700 µg/kg of body weight 2 hours before the surgical procedure, whereas the second group received clonidine orally at a dose of 2 mg/kg of body weight, 90 minutes before surgery. Subsequently, the volume of bleeding was calculated based on the amount of blood collected via suction and in blood-soaked gauze, which was previously weighed. Results Among the 92 patients who underwent rhinoplasty, 82% were women. The mean age and standard deviation (SD) of individuals who underwent rhinoplasty were 29.22 ± 8.50 years. There were no significant differences between the two treatment groups in terms of age, gender, and body mass index. The volume of blood collected via suction during rhinoplasty, categorized into surgery duration <63 minutes and ≤63 minutes, showed a significant difference between the 2 treatment groups. Conclusion The use of tranexamic acid, compared with clonidine, resulted in lesser intraoperative bleeding and better surgical field quality. Considering the superior effectiveness of tranexamic acid in reducing intraoperative bleeding, it is recommended to use tranexamic acid instead of clonidine in rhinoplasty.

Abstract
INTRODUCTION Nasal and sinus surgery, especially using endoscopy, relies upon adequate haemostasis to be safe and effective. Often other haemostatic methods, such as cautery are not viable, and other methods must be employed. This study examines the effectiveness of dexmedetomidine in controlled hypotension and for surgical field visibility in endoscopic sinus surgery and other nasal surgeries. REVIEW METHODS A literature search was conducted in PubMed, Scopus, CINAHL and Central for randomised controlled trials using dexmedetomidine for controlled hypotension in adult patients undergoing endoscopic sinus surgery or other nasal surgery. Meta-analysis of mean differences and single means were performed. RESULTS Of 935 identified studies, 31 met the inclusion criteria. A statistically significant difference in Fromme-Boezaart surgical field visibility scores was found comparing dexmedetomidine to placebo (p < 0.00001) and propofol (p < 0.0001), but not other agents. A significant difference in intraoperative blood loss volume was found compared with placebo (51.5mL, p < 0.00001) and propofol (13.6mL, p < 0.0001), but not other agents. CONCLUSION Dexmedetomidine demonstrated significantly improved surgical field visibility and blood loss volume compared with placebo and propofol, but not other agents. Dexmedetomidine is viable and useful for controlled hypotension in nasal surgery. Choice of controlled hypotension agent should follow patient and procedure-specific considerations.

Abstract
BACKGROUND Tranexamic acid (TXA) is a versatile antifibrinolytic agent that is widely used in modern surgeries. This review assessed the safety and efficacy of intravenous (IV) TXA in plastic surgery versus controls. METHODS This review selected English-language Randomized controlled trials (RCTs) evaluating IV TXA effects in plastic surgery from four electronic databases, PubMed, Web of Science, Embase, and Cochrane Library up to April 9, 2023. Primary outcomes were blood loss volume (BLV) and transfusion occurrence, with operation time and surgical field assessment as secondary outcomes. IV TXA-related complications were also important indicators. Meta-analyses and qualitative analyses were conducted and the quality of the evidence was assessed. RESULTS Thirty RCTs with 2150 patients were included. The total standard mean difference (SMD) of BLV and pooled relative risk of transfusion occurrence between the IV TXA and the control groups were - 1.11 (95% CI, - 1.42 to - 0.80) and 0.36 (95% CI, 0.23 to 0.55) respectively, indicating a significant blood loss reduction with IV TXA treatment, while an ambiguous outcome of operation time was observed, with an SMD of - 0.22 (95% CI, - 0.42 to - 0.02). The quality of evidence for BLV and transfusion occurrence was low and medium, respectively. A quantitative analysis of surgical field assessment was not performed because of the substantial heterogeneity in scoring methods. No IV TXA-related complications were observed. CONCLUSIONS In plastic surgery, IV TXA administration results in less blood loss, reduced need for transfusion and better surgical fields but probably does not increase the risk of adverse events.

Abstract
OBJECTIVES This study was conducted to determine the knowledge, practice, and barriers regarding the use of tranexamic acid (TXA) for the prevention and treatment of postpartum hemorrhage (PPH) among health care providers in Enugu, Nigeria. METHODS A cross-sectional study was conducted among health professionals (doctors, pharmacists, and nurses) in two Nigerian tertiary teaching hospitals (one federal and one state). A total of 220 questionnaires were distributed and 207 were returned (response rate: 94%) and analyzed using SPSS for inferential statistics with a level of significance of P < 0.05. RESULTS Only 23.7% of the respondents had good knowledge of TXA use in PPH (P < 0.001), and awareness of the recent World Health Organization (WHO) recommendation on the use of TXA for PPH was low (19.8%, P < 0.001). The majority of the respondents had neither prescribed nor dispensed TXA (30%, P < 0.001). Very few respondents used TXA for all cases of PPH (16.4%, P < 0.001). Barriers against its use include nonawareness of the latest WHO recommendation, preference for other uterotonics, and cost of the drug. CONCLUSIONS There was poor knowledge of TXA, poor awareness of its recommendation, and low use for PPH among different cadres of health care providers.

Abstract
BACKGROUND Septorhinoplasty (SRP) is one of the most commonly performed procedures in the world for functional and aesthetic purposes. The present study was aimed to compare the effects of hypocapnia and hypercapnia regarding the total amount of intraoperative bleeding, surgical field quality, and surgeon satisfaction level. METHODS In this randomized prospective clinical study, eighty patients with American Society of Anesthesiologists I-II and were 18-45 years old scheduled for septorhinoplasty were randomly allocated to group hypocapnia [end-tidal carbon dioxide (EtCO2) 30 ± 2 mmHg] and group hypercapnia (EtCO2 40 ± 2 mmHg). We evaluated the total amount of intraoperative bleeding, the surgical field quality, surgeon satisfaction level, hemodynamics and peri- and postoperative adverse events. RESULTS Group hypocapnia significantly reduced the total amount of intraoperative bleeding (p < 0.001). The surgical field quality and surgeon satisfaction level in group hypocapnia were significantly better than group hypercapnia (p < 0.001). EtCO2 levels of group hypocapnia were significantly lower than group hypercapnia at all time points (p < 0.001 for all time points). There were no significant differences between the groups in terms of heart rate and mean arterial pressure at all time points. There were no significant differences between the groups in terms of adverse events CONCLUSIONS: The results of this double-blind randomized clinical trial showed that reducing the amount of intraoperative bleeding for patients with hypocapnia undergoing SRP through known methods (e.g., reverse Trendelenburg head-up position, positive end-expiratory pressure limiting, controlled hypotension, and use of topical vasoconstrictors, corticosteroids, and tranexamic acid) would improve the quality of the surgical field and raise the surgeon satisfaction level.

Abstract
Introduction The quality of the surgical field during the surgery is impaired when bleeding occurs. This study compared the effect of tranexamic acid and dexmedetomidine on the rate of bleeding during endoscopic sinus surgery (ESS). Materials and Methods In this one-blind clinical trial, 72 patients with chronic rhinosinusitis who were candidates for ESS at Be'sat Hospital in Hamedan were randomly assigned to two groups. Group A received dexmedetomidine at a dose of 1μg/kg, and group B received tranexamic acid at a dose of 10mg/kg immediately after induction of anesthesia intravenously within 15 minutes. The two groups were evaluated and compared regarding the quality of the surgery field with the Boezaart scale, volume of intraoperative bleeding, hemodynamic changes, and complications up to 90 minutes after the beginning of surgery. Results The mean volume of intraoperative bleeding in group A (181.67±86.66) was significantly higher than in group B (110.28±61.23) (P =0.000). At 15, 30, and 60 minutes, the quality of the surgical field in group B was better than group A (P =0.038), while at 90 minutes, there was no statistically significant difference (P =0.450). The mean arterial pressure in group A at 15 minutes was higher than in group B (P=0.003); at 60 and 90 minutes, it was lower, and the difference was statistically significant (P =0.01). On the other hand, in 30 minutes, the mean arterial pressure in group A was higher than in group B, without a significant difference (P =0.07). Moreover, there was no statistically significant difference between the average surgery time (P = 0.25) and the frequency of complications (P =0.405). Conclusions Based on the results, tranexamic acid is preferable to injectable dexmedetomidine to control and reduce bleeding during ESS.
