International journal of physiology, pathophysiology and pharmacology. 2022;14(4):233-239
Abstract
BACKGROUND Adenotonsillectomy is a safe and common operation to remove adenoids and tonsils. Here we decided to compare the two dosages of tranexamic acid and their effects on hemodynamic changes and anesthesia-related indexes during surgical interventions. METHODS This is a double-blinded clinical trial performed in 2019-2020 on 64 children who were candidates for adenotonsillectomy. The patients were randomly divided into two groups of 32 based on the table of random numbers. Group A received 5 mg/kg slowly tranexamic acid for 10 minutes and group B received 10 mg/kg tranexamic acid slowly for 10 minutes. The study protocol was approved by the Research committee of Isfahan University of Medical Sciences and the Ethics Committee has confirmed it (Ethics code: IR.MUI.MED.REC.1398.639) (Iranian Registry of Clinical Trials (IRCT) code: IRCT20171030037093N33, https://en.irct.ir/trial/46553). RESULTS The mean volume of intraoperative bleeding in children in group A is significantly higher than in children in group B (P < 0.05). However, no significant difference was observed between the length of stay in recovery and the duration of extubation and the mean dose of propofol in the two groups (P > 0.05). The mean arterial oxygen saturation of children in both groups increased significantly over time (P < 0.05). However, no significant difference was observed between the two groups (P > 0.05). According to the results, the mean HR in both groups decreased significantly over time (P < 0.05). In addition, the mean HR in children in the group B was significantly lower than children in the group A (P < 0.05). CONCLUSION Administration of 10 mg/kg of tranexamic acid during tonsillectomy is associated with lower amounts of bleeding and lower heart rate than 5 mg/kg dosage. These results were in line with most previous studies.

Abstract
PURPOSE To evaluate the efficacy of topical tranexamic acid (TXA) in reducing intraoperative and immediate postoperative bleeding during functional endoscopic sinus surgery (FESS) among patients with chronic rhinosinusitis with nasal polyposis (CRSwNP). METHODS This is a double-blind randomized clinical trial, involving 26 patients with CRSwNP, who underwent FESS for failed medical therapy. The intervention nostril was packed with ribbon gauze soaked in 500 mg/5 ml TXA. The control nostril was packed with ribbon gauze soaked in Moffett's solution, containing 2 ml 10% cocaine, 1 ml adrenaline 1:1000, and 4 ml 0.9% sodium bicarbonate. Both nostrils were packed for 15 min before FESS. Intraoperative bleeding was recorded in the initial 30 min after commencing the surgery. The recordings were reviewed by two surgeons using Boezaart's scoring system. The scores were taken at 15 and 30 min of surgery. The mean score was then calculated. At the end of the surgery, the intervention nostril was packed with Merocel(®) soaked in 500 mg/5 ml TXA and the control nostril was packed with Merocel(®) soaked in normal saline. The amount of bleeding within 24 h post-surgery was evaluated using a bolster gauze. RESULTS There was no significant difference in intraoperative bleeding between the intervention (1.54 ± 0.71) and control nostrils (1.69 ± 0.55) with p = 0.172. The amount of bleeding in the postoperative period was significantly reduced in the intervention nostril (1.33 ± 0.55) compared to the control nostril saline (1.81 ± 0.48) with p = 0.001. CONCLUSIONS We found that the nasal packing soaked in TXA reduced intraoperative and immediate postoperative bleeding. It is a safe, efficacious and cost-effective alternative to Moffett's solution during FESS and also an alternative to normal saline post-surgery among patients with CRSwNP.

The Annals of otology, rhinology, and laryngology. 2022;:34894221086086
Abstract
OBJECTIVE Our aim is to evaluate the effect of topical tranexamic acid (TA) on bleeding and surgical quality field in the functional endoscopic sinus surgery (FESS). METHODS A total of 74 patients who underwent FESS due to chronic rhinosinusitis were included. The patients were randomized into 2 groups. TA group (n = 37) received a topical cotton pledget soaked with TA and placebo (PL) group (n = 37) received a pledget soaked with saline solution. RESULTS A significant effect was noted for the TA group versus the PL group in the grade 1 of the Boezaart scale at 35 minutes (4 for TA group and no case for PL group). This effect was absent for higher grades. We did not notice a significant effect between the 2 groups at 5 minutes. Blood loss was 359 ml in the TA group versus 441 ml in the PL group. No significant change was observed between the 2 groups concerning the blood parameters. No side effects were reported. CONCLUSION Despite its safety when administrated locally and its low cost, TA provides limited effect on quality of surgical field after 35 minutes of the start of FESS in the patients with chronic rhinosinusitis. This effect was absent at the start of the intervention and when analyzing the blood loss and hematologic parameters.

International journal of physiology, pathophysiology and pharmacology. 2022;14(3):177-186
Abstract
BACKGROUND Bleeding in Dacryocystorhinostomy (DRC) limits the surgeon's sight and access. Tranexamic acid, Remifentanil, and Hydralazine reduce intraoperative blood loss. However, no study has been carried out to compare the efficacy of the latter drugs during DCR surgery. METHODS Ninety healthy candidates for DCR surgery with chronic Dacryocystitis (aging 20-80) were randomly assigned in groups of 30 to receive low doses of Tranexamic acid (TXA) (10 mg/kg with a maximum dose of 1000 mg), Remifentanil (0.1 µ/kg), or Hydralazine (0.1 mg/kg). All drugs were infused over 15 minutes before the initiation of surgery. The primary outcome was the bleeding volume during the surgery and until 2 hours in recovery. This study was approved by the Iranian Registry of Clinical Trials with the code of IRCT20210614051574N10 (https://en.irct.ir/trial/62759). RESULTS Thirty patients (mean age ± SD: 50.48±13.4) were investigated. Mean blood loss volume was lower in Remifentanil and Hydralazine groups compared with the TXA group (P<0.05); there was no significant difference (P>0.05) in bleeding volume between Remifentanil and Hydralazine groups (Tranexamic acid group: 146.83±91 ml, Remifentanil group: 77.6±52.1 ml, Hydralazine group: 80.0±48.7 ml, 95% confidence interval, P<0.05). CONCLUSION Our results show that Remifentanil and Hydralazine are more effective than Tranexamic acid in bleeding control.

Abstract
OBJECTIVES Hemorrhagic events related to surgical field is a common disturbing complication which could worsen the outcomes of operation. This study aimed to evaluate how applying of topical tranexamic acid (TXA) could affect bleeding related to septorhinoplasty operation. MATERIAL AND METHODS This double-blind controlled trial study finally evaluated 198 candidates for septorhinoplasty repair who were randomly allocated to two groups: TXA receivers (5 mg/kg) and control group (received 5 mg/kg of saline 0.9 %). Then cumulative volume of hemorrhage was calculated by adding total volume of suctioned blood and numbers of fully blood-filled surgical gauzes (15 mL in each). Additionally postoperative 24 h volume of hemorrhage was measured by counting number of bloody surgical gauzes. RESULTS Of all participants, 90 % were female. The mean age was 26 ± 7 years. Total cumulative volume of hemorrhage during surgery was significantly diminished when topical TXA was applied (p < 0.0001). Additionally drier field of operation was illustrated postoperatively in patients received topical TXA (2 % & 28 % in TXA and saline 0.9 % receivers, respectively) (p < 0.001). CONCLUSION Using topical TXA could decrease bleeding volume and make surgical field of septorhinoplasty drier either during surgery or postoperatively.

Tzu chi medical journal. 2021;33(2):181-187
Abstract
OBJECTIVE The aim of the present study was to evaluate and select the optimal dosage of tranexamic acid (TXA) to reduce blood loss during cleft palate surgery in children. MATERIALS AND METHODS This randomized double-blind clinical trial was performed on 80 children under 3 years of age that were candidates for cleft palate surgery. These children were divided into four groups as follows: the first, second, and third groups received 5, 7.5, and 10 mg/kg of TXA, respectively. Moreover, the fourth group was considered as the control group. Before induction of anesthesia and then every 15 min during the surgery, some parameters such as mean arterial pressure, heart rate, SpO(2), and ETCO(2) were recorded. Moreover, the amount of blood loss during the surgery, the level of surgeon's satisfaction, and incidence rate of complications were assessed and recorded. RESULTS The amount of blood loss during the surgery in TXA groups receiving dosages of 5, 7.5, and 10 mg/kg with the means of 63.75 ± 10.62, 61.25 ± 15.03, and 61.00 ± 14.29, respectively, was significantly lower than that of the control group with the mean of 92.25 ± 19.83 (P < 0.001). Moreover, no significant difference was found between the three groups receiving TXA dosages in terms of the amount of blood loss, the level of surgeon's satisfaction (P > 0.05). CONCLUSION According to the results of the present study, all three dosages of TXA had a significant role in reducing blood loss in cleft palate surgery. Given the potential for increased risk of side effects from the drug, it seems safe to use the minimal dosage of this drug to control and reduce blood loss during cleft palate surgery in children <3 years of age.

Abstract
BACKGROUND Intraoperative bleeding during functional endoscopic sinus surgery (FESS) poses a challenge to both surgeon and anesthetist. The primary aim of this study was to evaluate the effectiveness of local, intravenous and combined use of tranexamic acid (TA) in improving the surgical field quality during FESS. METHODS We conducted a randomized controlled double-blinded prospective trial on 120 patients scheduled for elective FESS. After induction of general anesthesia, patients were randomly and evenly assigned to one of four groups; IV TA, local TA, both IV and local TA, and placebo. Surgical field was assessed using five-point Boezaart scale. Total fentanyl and esmolol consumption, operative time, recovery time, and postoperative complications were recorded. RESULTS Surgical field quality score was the best in IV and local TA group compared to others (p < 0.001). Mean operative time was found significantly shorter in IV and local TA group than placebo one. Total fentanyl consumption was significantly lower in IV and local TA group comparing to others (p = 0.025). Mean recovery time was significantly shorter for IV and local TA group compared to others. Total fentanyl consumption was significantly lower in IV and local TA group comparing to others. No significant differences were found of mean arterial pressure and heart rate decline in four groups. None of the patients in four groups required esmolol administration. No statistically significant differences were found in change of hemoglobin, hematocrit, prothrombin time, and partial thromboplastin time over time in all groups. CONCLUSION The combined use of topical and intravenous TA provided the best surgical field in FESS, less fentanyl consumption, and less recovery time without causing significant side effects.

Abstract
BACKGROUND Even a small amount of bleeding during nose surgery can impair the surgeon's vision, prolong the duration of operation, and affect surgery quality; therefore, various techniques have been proposed to control the bleeding. The aim of this study was to compare the efficacy of the local use of tranexamic acid (TXA) in the dry field of surgery. METHOD This randomized, double-blinded, controlled trial was conducted in the operation room of Imam Reza Hospital, Tehran, Iran, from January 10, 2016 to February 8, 2017. Sixty patients with age range from 20 to 60 years and the American Society of Anesthesiologists physical status classes I candidates who require septoplasty enrolled. Patients were randomized through white and black cards to receive either syringes. Thirty patients in the intervention group received lidocaine + adrenaline + TXA and 30 patients in the control group received lidocaine + adrenaline. Bleeding volume accumulated in the suction chamber, the nasopharyngeal pack, and hemodynamic variations were measured. Surgeon's satisfaction scores and suitability of operation field were obtained from the surgeon by using the Likert scale and Boezaart grading scale, respectively. RESULTS The intervention group had a higher score of surgeon satisfaction [4.1 vs 3.16 in the control group (P = 0.001)] and fewer hemodynamic variations. The mean bleeding volume in the intervention was 187.23 ± 54.61 mL and in the control group was 341.22 ± 49.17 mL (P = 0.001). The mean Boezaart score (suitability of operation field) in the intervention group was 1.8 (score range: 1-3) and in the control group was 2.53 (score range: 2-4) and it was statistically significant (P = 0.001). CONCLUSION The local use of TXA + lidocaine + adrenaline is associated with reduced bleeding, greater surgeon satisfaction, reduced need for Karpol injection, and better hemodynamic stability.

Abstract
In this blinded clinical trial, we attempted to compare the efficacy and safety of administering tranexamic acid, dexmedetomidine and nitroglycerin in preventing intraoperative bleeding and improving the quality of the surgical field during septorhinoplasty under general anesthesia. A total of 105 patients scheduled for septorhinoplasty were enrolled and randomly assigned into three groups based on the balanced-block randomization method. First group received 1 μg/kg intravenous injection dexmedetomidine, second group received 10 mg/kg intravenous injection tranexamic acid and third group received 0.5 μg/kg nitroglycerin, intravenously. The study sample was composed of 105 participants with the total mean age of 25.85 ± 6.52 years, and 59.05% of participants were female and the mean of body mass index was 24.34 ± 2.57 kg/m(2). The results showed that there was no statistically significant difference in terms of arterial oxygen saturation, mean arterial pressure, heart rate, bleeding rate, duration of surgery, and surgeon satisfaction among the three groups; however, there was a significant difference in the extubation time, recovery time and the dose of administered propofol among the three groups. Dexmedetomidine reduced the dose of administered propofol while increasing the extubation time and recovery time. In the tranexamic acid group compared with the other two groups, the recovery time was shorter. However, all the three drugs could reduce intraoperative bleeding and lead to surgeon satisfaction. It can be concluded that all these three drugs can be utilized to control bleeding and improve the quality of the surgical field but the ultimate decision lies with the anesthesiologist's judgment and the conditions of the patient. The study protocol was registered in the Iranian Registry of Clinical Trials (registration No. IRCT20141209020258N121) on September 24, 2019 and it was ethically approved by the Ethical Committee of Arak University of Medical Sciences (approval No. IR.ARAKMU.REC.1397.355) on February 24, 2019.

Kuo CC, DeGiovanni JC, Carr MM
The Annals of otology, rhinology, and laryngology. 2021;:34894211045264
Abstract
OBJECTIVE There is controversy regarding the efficacy and safety of tranexamic acid (TXA) in reducing tonsillectomy-related hemorrhage. We conducted a systematic review and meta-analysis to evaluate the prophylactic role of TXA in tonsillectomy. METHODS We searched 6 databases to identify studies that directly compare the effect of TXA versus controls in tonsillectomy patients. Standardized mean difference was applied to summate the findings across the studies. Dichotomous data were expressed as relative risk. RESULTS Ten studies representing a total of 111 898 patients were included. The pooled results showed a significant reduction of intraoperative blood loss by 39.02 ml (SMD = -1.05, 95% CI: -1.91 to -0.20, P = .016) and the rate of post-tonsillectomy hemorrhage (RR = 0.42, 95% CI: 0.28 to 0.65, P < .0001), with no significant difference in reduction of further intervention risk (RR = 0.78, 95% CI: 0.45 to 1.35, P = .373). CONCLUSIONS Overall, this study indicates that TXA may reduce blood loss and frequency of post-operative hemorrhage associated with tonsillectomy. Further large, high-quality clinical trials are still needed to explore TXA's effect on post-tonsillectomy hemorrhage and the safety of its use.
