Background: Acetabular fracture surgeries are frequently accompanied by protracted and severe perioperative pain, and there is no consensus on optimal pain relief management. Aim: This study aimed at comparing the analgesic efficacy of fascia iliaca compartment block (FICB) and quadratus lumborum block (QLB) in patients with acetabular fractures undergoing surgery using the Stoppa method. Methods: In this double-blind, randomized, noninferiority clinical trial, adult patients undergoing spinal anesthesia for acetabular fracture surgery, in Imam Hossein Hospital, Tehran, Iran (IRCT20191114045435N1), were randomly divided into two groups: FICB (n = 22) and QLB (n = 24). The visual analog scale (VAS) was used to assess the pain intensity at different times for all participants. In addition, the dose of fentanyl required to induce the patient to sit for spinal anesthesia and the pain intensity were evaluated. Moreover, the duration of analgesia and the total amount of morphine consumed in the first 24 h following surgery were evaluated, analyzed, and compared between the two study groups. Results: FICB and QLB demonstrated effective comparative postoperative analgesic profiles following acetabular fracture surgery; however, no significant differences in VAS values were observed between the two groups during the study. FICB experienced reduced cumulative fentanyl consumption during spinal anesthetic placement, whereas QLB had a significantly lower total morphine demand in the initial postoperative 24 h period. Conclusion: The lateral QLB and FICB can be introduced as effective routes for analgesia in acetabular fracture surgery using the Stoppa method. Clinical Trial Registration.

Background: To prove the position of aripiprazole as a preventive and safe agent in delirium in patients admitted to the intensive care unit (ICU), it is necessary to conduct randomized controlled clinical trials with appropriate design. Materials and Methods: In this study, 80 patients were randomly divided into two groups of 40. Group A received placebo mart for one week, and group B received 15 mg aripiprazole daily (dissolved in 10 cc) daily. As a criterion for assessing delirium, the Confusion Assessment methods for the ICU (CAM-ICUs) were evaluated daily for patients. At the end of the study, the trends of CAM-ICU and CAM-ICU changes on day 7 were compared between the two groups. All statistical tests were performed in two domains with a significance level of 5% using the t-test. Statistical Package for the Social Sciences (SPSS) 21 software was used to analyze the data. Results: The use of aripiprazole in the studied indices was not statistically significant (P > 0.05). The results related to the length of stay in the ICU, showed that although the use of aripiprazole has reduced the length of hospitalization of patients in the ICU, this rate of reduction, was not significant (P > 0.05). Conclusion: The use of aripiprazole with the approach of reducing the risk or controlling the occurrence of delirium on patients admitted to the intensive care unit, despite creating some beneficial effects such as reducing the length of hospital stay in the ICU, cannot be clearly and significantly effective.
Background: Controversy remains about the positive role of music during general anesthesia and postoperative recovery. We, therefore, tested the hypothesis that intraoperative exposure to classical music reduces the propofol necessary to maintain the bispectral index (BIS) close to 50 during vitrectomy surgery. Materials and Methods: This double-blind clinical study is evaluating 50 patients undergoing vitrectomy surgery under general anesthesia. Patients were randomly assigned to music and white noise groups, and relevant sounds were played to patients after induction of anesthesia. The two groups were compared for the use of propofol as an anesthetic to maintain a BIS near 50 and for postoperative pain, anxiety, nausea, and vomiting. Results: Propofol consumption to maintain the set BIS score was much lower in the music group than in the white noise group (78.72 ± 25.76 microgram/kg/min and 117.91 ± 36.78 microgram/kg/min, respectively, P-value = 0.000). Postoperative pain scores were also much lower in the music group than in the white noise group (P-value = 0.000) and anxiety levels between these two groups did not differ (P-value = 0.870). No patient in the music group had complaints of postoperative nausea and vomiting (PONV) compared to six patients in the white noise group (P-value = 0.011). Conclusions: Listening to music during general anesthesia for vitrectomy surgery can reduce the use of anesthetics, postoperative pain, and PONV. Further, controlled studies are necessary to confirm our results.
Objectives: Excessive blood loss is a critical complication of total hip arthroplasty. We intended to determine whether preoperative fibrinogen administration reduces perioperative bleeding and the need for blood transfusion in total hip arthroplasty surgery. Methods: In 4 months, 178 patients who underwent total hip arthroplasty were randomly assigned equally to intervention and placebo-control groups in a double-blinded, parallel two-arm randomized controlled trial. Both intravenously, 30 min before the start of the surgery, the intervention group received two grams of fibrinogen concentrate dissolved in 100 ml of distilled water. In contrast, the control group received 100 ml of normal saline solution. The amount of postoperative blood loss served as the main result, and the requirement for blood transfusions served as the secondary outcome. Results: In comparison to the placebo, administering fibrinogen concentrate considerably reduced the amount of blood loss (P=0.001) and the requirement for blood transfusions (P=0.004). Patients who got fibrinogen concentrate experienced no side effects. In addition, patients in the fibrinogen group had significantly lower hemoglobin and higher fibrinogen levels in the recovery room and received lesser blood transfusions (P<0.005) than the placebo group. Conclusion: In total hip arthroplasty, fibrinogen concentrate lessens postoperative bleeding and the requirement for blood transfusions.
BACKGROUND: The coronavirus, which is caused by acute respiratory syndrome, appeared in Wuhan, China, in December 2019 and gradually spread around the world until almost all countries became infected with the coronavirus. In Iran, the outbreak of coronavirus began on February 21, 2020, with the report of infection of two people in the city of Qom. The aim of this study is to evaluate the clinical findings of neonates born to pregnant women with corona disease. MATERIALS AND METHODS: During this case study (February 21 to November 30, 2020), out of 88 pregnant mothers who referred to the hospitals of Shahid Beheshti University of Medical Sciences, 44 live neonates were born from 42 pregnant women with COVID-19, who were evaluated for clinical signs by studying their files and reported as a case series, due to limited samples, No statistical analysis of the study was performed. RESULTS: In studies of clinical records of hospitalized mothers and infants, among the polymerase chain reactions (PCRs) provided for all infants, one PCR was reported positive 2 days after birth, whereas this infant 10 min after birth, immediately after routine procedures, due to positive mother's PCR was isolated from the operating room. However, all of the infant's clinical symptoms were normal during the 3-day hospital stay for routine postpartum care. Twenty-eight days after birth, the baby was reevaluated for clinical, laboratory, and chest X-ray symptoms, all of which were normal. The PCR of other neonates was negative, and five intubated neonates, two twin, and two single died, and the other neonates were discharged. In evaluating the clinical records of mothers of these infants, the mean age is 30 years, and the average gestational age is 35 weeks, 32 cases of caesarean section, and 10 cases of normal delivery. CONCLUSION: We describe epidemiological data, demographics, signs and symptoms on admission, laboratory results, comorbidities, infection COVID-19 in the mothers and neonates, chest radiography and computed tomography findings, treatment received for COVID-19, and clinical maternal, fetal, and neonatal outcomes. Due to the fact that the study population is small consist of 42 mothers with COVID-19 infection, among all PCR samples from infants born to COVID-19 positive mothers, the PCR result of one case was positive, and the rest of was negative. Therefore, vertical transmission of COVID-19 through the placenta to the fetus cannot be confirmed or denied, nor can the COVID-19 confirmed or denied the baby's postnatal complication during pregnancy.
BACKGROUND: "Simulated-patient scenarios and role-playing" and OSCE are among the many non-traditional education methods with variable results in different clinical settings. OBJECTIVES: This cross-sectional study was performed to assess the correlation between the results of these two methods in senior anesthesiology residents, with a special focus on four of the six ACGME core competencies. METHODS: During two years, senior anesthesiology residents were subject to "simulated patient scenario and role-playing" sessions. Two faculty members took the role of the patient and one of the relatives. An objective checklist with 15 items was prepared to be rated by other department faculty members. Meanwhile, an ordered pattern of OSCE was prepared to cover four core competencies that were more related to this academic process (from a total of six core competencies). The mean and standard deviation of the score of each of the 15 items in the checklist were calculated. The correlation between cumulative checklist scoring results and OSCE exam results was assessed. A P value of less than 0.05 was considered significant. RESULTS: A total of 40 senior anesthesiology residents, with 344 assessments by faculty members in 40 sessions, were enrolled in the study. The questionnaire's Cronbach's alpha reliability was 0.74. No statistically significant disparity was detected between the results of the two assessment methods, while the results of the two assessments had a significant correlation (two-tailed correlation coefficient = 0.886; P value < 0.001). CONCLUSIONS: There was an objective relationship between the results of "simulated patient scenario and role-playing" strategies and the results of OSCE exams using an observer-based rating method. Thus, they could be used as surrogates in the assessment of core clinical competencies of senior anesthesiology residents.
BACKGROUND: Spinal anesthesia is an important and commonly used method for surgical anesthetic in operating rooms. However, even with identical drug dosage and administration mode, the extent of drug distribution in vivo is highly variable and difficult to control. Preanesthetic administration of fluids immediately before spinal anesthesia (preload) is normal practice. The choice of fluid type may affect drug distribution as well as the duration and level of the block. OBJECTIVES: We examined whether preloads of normal saline, Ringer, or hydroxyethyl starch has different effects on the time it takes to reach maximum block, and the distribution and duration of spinal block level. PATIENTS AND METHODS: This was a randomized trial and the 150 patients selected were evenly divided into three groups and given; normal saline, Ringer, or hydroxyethyl starch 130/0.4f luids. Preload was given at 10 mL/kg for the normal saline and Ringer groups, and 5 mL/kg for the hydroxyethyl starch group, 10 min before the spinal anesthesia. Sensory block levels were recorded every 5 min until 30 min after spinal anesthesia and then at 60 and 90 min. Time taken to reach maximum and median sensory block, maximum and median level of block, duration of block, and hemodynamic status were recorded. RESULTS: There were no statistically significant differences in the demographic characteristics between the three groups. Maximum block was higher in normal saline compared to Ringer (P = 0.029). Time taken to reach maximum block was greater in Ringer compared to both normal saline (P = 0.001) and hydroxyethyl starch (P = 0.003). Normal saline had a longer duration of sensory block T10 compared to Ringer and hydroxyethyl starch (P = 0.03). CONCLUSIONS: Preload fluids have an impact on the level, distribution and duration of sensory block in spinal block. Of the three fluids, normal saline produced the greatest maximum and longest duration of block, whereas time taken to reach maximum block was longer in the Ringer group.
INTRODUCTION: Airway management, especially outside the operating room, needs meticulous observation in order to avoid certain risks, such as; endotracheal tube (ETT) disloca-tion, esophageal intubation, and unwanted extubation. ETT or tracheostomy dislocation is responsible for one-half of death or brain damage cases in the ICU. Despite appropri-ate fixation of an ETT, the previously mentioned compli-cations can still occur . A broken ETT and consequent airway obstruction may lead to lethal complications. CASE PRESENTATION: We report a case of death caused by tracheal tube aspiration, where it was located distal to the vocal cords, with a part of it entering the right bronchus and the mediastinum, after tearing the right bronchus. DISCUSSION: The vigilance and experience of medical personnel in the ICU, appropriate IV sedation, and using a bite block are the best ways to prevent mortality caused by aspiration of an ETT in all intubated patients.
BACKGROUND: The ability to identify critically ill patients who will not survive until hospital discharge may yield substantial cost savings. The aim of this study was to validate the mortality prediction model II (MPM II) in in-hospital mortality of critically ill patients for quality management and risk-adjusted monitoring. METHODS: The data were collected prospectively from consecutive admissions to the Intensive Care Unit of Imam Hossein Medical Center in Tehran. A total of 274 admissions were analyzed using tests of discrimination and calibration of the logistic regression equation for mortality prediction model II at admission (MPM0 II) and at 24th hour (MPM24 II). RESULTS: The mortality prediction model II exhibited excellent discrimination (receiver operating characteristic curve area). Calibration curves and Hosmer-Lemeshow statistics demonstrated good calibration of both models on outcome. CONCLUSION: We recommend using mortality prediction model II in Iranian ICUs for routine audit requirements. Mortality prediction model II is not affected by the standards of treatment after admission to ICU. The information needed to calculate mortality prediction model II is easy to collect, and the model is applicable to all ICU admitted patients.
