ABSTRACT
Background: Hysterectomy is one of the most common gynecology surgeries. This study aimed to compare perioperative bleeding in transabdominal and transvaginal hysterectomy. Materials and Methods: This prospective, double-blind, randomized, controlled clinical trial was performed on 80 patients undergoing hysterectomy referred to Shahid Beheshti Hospital, Isfahan, Iran. Patients were divided into two groups of 40; the first group (T) received 1 g intravenous tranexamic acid (TXA) for 20 min preoperatively. The second group (S) received 10 cc normal saline as placebo. Blood samples were taken before and 12 h after surgery for assessment of hemoglobin, hematocrit, and platelet count, the prothrombin time, activated partial thromboplastin time, and serum creatinine as well as volume of blood transfusion. Results: There were no significant differences between the two groups in heart rate, diastolic blood pressure (BP), systolic BP, and mean arterial pressure before, during, and after surgery (P > 0.05). There was no significant difference in blood variables before and after surgery (P > 0.05) except the platelet count that was in the normal range in both groups after surgery (P = 0.022). The mean volume of blood transfused in the case group was significantly lower than the control group during surgery (P = 0.008) and 12 h after surgery (P = 0.01). Conclusion: The prophylactic administration of TXA results in a significant reduction in need for blood transfusion and the duration of surgery. Given the lower risks of using TXA compared to the other drugs, it is recommended in hysterectomy to control bleeding.
ABSTRACT
OBJECTIVE: In this study, we aimed to compare the effects of intravenous dexamethasone and methylprednisolone on the treatment of inpatients with COVID-19. METHODS: In this randomized clinical trial, 143 patients under 80 years of age with moderate to severe COVID-19 were enrolled and randomly assigned to two groups: dexamethasone (8 mg/day) and methylprednisolone (60 mg/day in two divided doses). The primary outcome was the length of hospital stay. The secondary outcomes included: duration of oxygen therapy, absolute leukocyte and lymphocyte count, hypokalemia, hyperglycemia, intensive care unit admission, and mortality in the two groups for 28 days. Data were analyzed by SPSS version 26 using t-test, chi-square, and analysis of variance. RESULTS: The duration of hospitalization was significantly (P <0.001) shorter in the dexamethasone group than in the methylprednisolone group (8 [95% confidence interval [CI]:6-10] and 11 [95% CI: 7-14], respectively). In addition, the duration of oxygen therapy in the dexamethasone group (7 [95% CI: 5-9]) was significantly (P <0.001) shorter than in the methylprednisolone group (10 [95% CI: 5.5-14]). The mortality rate was 17.1% (95% CI: 8.1-26.1) in the dexamethasone group and 12.3% (95% CI: 4.6-20.0) in the methylprednisolone group, which was not statistically significant (P = 0.46). CONCLUSION: Results showed better effectiveness of 8 mg/day dexamethasone compared with 60 mg/day methylprednisolone based on the shorter hospital stay, which can be considered in the therapeutic protocol of COVID-19. TRIAL REGISTRATION: IRCT20210223050466N1.

BACKGROUND: The present study was designed to evaluate the effectiveness of magnesium sulfate (MgSO4) in procedural sedation and analgesia (PSA) when combined with ketamine in patients with fractures in emergency departments and required short and painful emergency procedures. MATERIALS AND METHODS: In this study, 100 patients with fractures and dislocations who were presented to the emergency departments and required PSA for short and painful emergency procedures were randomly allocated to groups of ketamine plus MgSO4 or ketamine alone. Train of four (TOF) stimulation pattern was assessed using nerve stimulator machine and compared between groups. RESULTS: The mean age of studied patients was 46.9 ± 9.3 years old. 48% were male and 52% were female. No significant differences were noted between groups in demographic variables. The status of TOF, 2 min after the injection of ketamine (1.5 mg/kg), in both groups was similar. After the injection of the second dose of ketamine (1 mg/kg) the status of TOF in four patients in ketamine plus MgSO4 (0.45 mg/kg) group changed, it was three quarters but in ketamine group, the status of TOF in all patients was four quarters. The difference between groups was not statistically significant (P = 0.12). CONCLUSION: The findings revealed that for muscle relaxation during medical procedures in the emergency department, ketamine in combination with MgSO4 with this dose was not effective for muscle relaxation during procedures.
