Background: Given the importance of implementing lung protective strategies to prevent lung injury caused by ventilators and death of patients, it is necessary to monitor the current condition of hospitals and examine the relationship between the parameters set on the ventilators and patient mortality. This study conducted to determine the current state of ventilator setting and their relationship with mortality rate in patients under mechanical ventilation: a cross-sectional study. Methods: This is a cross-sectional study that was conducted between June to December 2020 in one of the hospitals affiliated to Tehran University of Medical Sciences. The initial tidal volume set on the ventilator was recorded for 304 patients under mechanical ventilation and then, their heights were measured and their tidal volumes were determined based on the standard formula. Other parameters set on the ventilator as well as systolic and diastolic blood pressures of patients were also recorded and their survival rate was investigated. The data was analyzed by SPSS software, using descriptive statistics and logistic regression model. Results: Among patients, who were under mechanical ventilation, 77.6% were hospitalized in intensive care units and the rest were hospitalized in general wards. The mean adjusted tidal volume for patients was 472.91 ± 32.13 ml. The mean peak inspiratory pressure and plateau pressure were 28.00±6.98 and 13.88±4.93 CmH2O, respectively. Also, 37.2% of patients died during the hospitalization. The results of adjusted odds ratio based on multivariate logistic regression model for predictors of mortality rate showed that the variables of patients' age [OR=1.040 (1.019-1.062)], the hospital’s general ward in comparison with the ICU [OR=11.379 (5.130-25.240)] and the peak inspiratory pressure [OR=1.072 (1.007-1.141)] had a direct and significant relationship with mortality rate (in all cases P<0.05). Meanwhile, the plateau pressure [OR=0.886 (0.808 -0.972)] had an inverse and significant relationship with mortality rate (P<0.05). Conclusion: Despite the recommendations regarding lung protective strategies, in some cases, some parameters set in the ventilator are outside the recommended levels, which can effect on patients mortality. So monitoring and controlling the implementation of lung protective strategies and paying attention to controlling pressures set on the ventilator are among measures that should be taken in medical centers in order to prevent lung injuries and maintain patient safety.

Background: The recently developed blade design of the Sanyar® video laryngoscope yields an exceptionally precise visualization of the larynx, thereby easing the process of tracheal intubation. Objectives: A non-inferiority clinical investigation, to assess the efficacy of the Sanyar® as compared to the Macintosh® direct laryngoscope for nasotracheal intubation in the context of maxillofacial surgeries. Methods: 78 patients for maxillofacial surgery were divided randomly into two groups and intubated through the nose using either the Sanyar® or Macintosh® laryngoscope after anesthesia was induced. The study measured intubation time and secondary objectives included success rate, attempts, and hemodynamic changes in two groups. Results: 40 eligible patients in the Sanyar® and 38 in the Macintosh® group were involved. Of all, 42(53.8%) were men and 36(46.2%) were women. The average age of patients in the Sanyar® and Mackintosh groups was (31.62±13.41) and (30.81±10.89), respectively. 39(98%) of the Sanyar® group and 33(86%) of the Macintosh® group had successful laryngoscopy and intubation, with a P-value<0.034. Sanyar® group had a significantly shorter intubation time than Macintosh® (P-value<0.001). Hemodynamic changes before and after laryngoscopy and intubation had no significant differences between the two groups. Conclusion: The Sanyar® video laryngoscope reduced the time of nasal tracheal intubation in maxillofacial surgery compared to direct laryngoscopy and improved the success rate of the first intubation attempt.

Pulmonary bullae typically occur either idiopathically or in the context of chronic obstructive pulmonary disease and pulmonary infections. Clinical manifestations of pulmonary bullae include cough, shortness of breath, and chest pain. In some cases, they may be asymptomatic. Differentiating between pneumothorax and pulmonary bullae can be challenging when they coexist. Therefore, obtaining a detailed patient history, conducting a physical examination, performing laboratory tests, and utilizing radiology studies are essential diagnostic tools that should be employed simultaneously. In this case report, we present a patient who developed a wide pneumothorax due to a penetrating chest wound caused by a knife. Initially, the large lung cavity, which had already formed due to tuberculosis, was misdiagnosed as a loculated pneumothorax.

Background: Idiopathic clubfoot deformity is a relatively common congenital pediatric foot deformity. A percutaneous Achilles tenotomy (PAT) is required to correct the equinus deformity as it is the most resistant component of clubfoot deformity. Although this procedure is mainly performed with local anesthesia, performing this procedure with general anesthesia has significant advantages. Aims: The purpose of this study was to compare the safety and efficacy of post-procedural pain management of PAT in the treatment of clubfoot with the Ponseti method when performed in a clinic setting with local anesthetic or under general anesthesia Methods: This is a multicentric prospective observational evaluation on children less than one year of age with idiopathic clubfoot whom referred for Ponseti casting and PAT. This procedure was done in the control group with local anesthesia and in the intervention group with Sevoflurane mask 8% (MAC 2) and maintenance of anesthesia with Sevoflurane mask 4% (N2O/O2, 50%). The neonatal infant pain scale (NIPS), the amount of milk, and mood changes were evaluated as a criterion to measure the pain level. Results: NIPS score in the intervention group was significantly lower than the control group. Children in the intervention group consume significantly more milk than the control group. Furthermore, 76% of children in the intervention group were classified as "calm," 24% as "relatively restless," and no child was classified as "severely restless." While in the control group, 54% of children were classified as "severely restless," and the remaining 46% as "relatively restless." Conclusion: Our result showed that using general anesthesia to perform achillotomy in the treatment of clubfoot in children could be associated with less pain in these patients and without significant complications.
背景：特发性马蹄内翻足畸形是一种较为常见的先天性小儿足部畸形。由于马蹄内翻足畸形是足部畸形中最难矫正的部分，因此需要进行经皮跟腱切开术（PAT）来矫正马蹄内翻足畸形。虽然该手术主要是在局部麻醉下进行，但在全身麻醉下进行该手术具有显著优势。目的：本研究旨在比较 PAT 术治疗马蹄内翻足与 Ponseti 法治疗马蹄内翻足的术后疼痛管理的安全性和有效性，前者是在诊所环境下使用局部麻醉，后者是在全身麻醉下进行的 方法：本研究是一项多中心前瞻性研究，旨在比较 PAT 术治疗马蹄内翻足与 Ponseti 法治疗马蹄内翻足的术后疼痛管理的安全性和有效性：这是一项多中心前瞻性观察评估，评估对象为一岁以内的特发性马蹄内翻足患儿，这些患儿被转诊接受 Ponseti 脚型固定和 PAT 治疗。对照组采用局部麻醉，干预组采用 8%（MAC 2）七氟烷面罩，并用 4%（N2O/O2，50%）七氟烷面罩维持麻醉。新生儿疼痛量表（NIPS）、奶量和情绪变化作为衡量疼痛程度的标准。结果干预组的 NIPS 评分明显低于对照组。干预组儿童的牛奶摄入量明显高于对照组。此外，干预组中 76% 的儿童被归类为 "平静"，24% 的儿童被归类为 "相对烦躁不安"，没有儿童被归类为 "严重烦躁不安"。而在对照组中，54% 的儿童被归类为 "严重躁动不安"，其余 46%的儿童被归类为 "相对躁动不安"。结论我们的研究结果表明，在治疗儿童马蹄内翻足的过程中，使用全身麻醉进行腱鞘切开术可以减轻患者的痛苦，而且不会出现明显的并发症。

Background: Today, the COVID19 pandemic is one of the most important health system challenges in the world, which doesn’t have specific treatment yet. It includes a wide range of respiratory and non-respiratory signs and symptoms, that lead to hospitalization and intensive care units. Methods: In this study, 78 patients in two groups of 39 patients were included. The case group included 39 COVID19 patients who had specified sign in CT scans and factors of viral infection, high serum ferritin, increased inflammatory factor in the blood. There were two intervention groups (receiving deferoxamine and vitamin C) and the control group (receiving only official protocol drugs of the country). All patients were admitted to the ICU of Shohada-e-Tajrish Hospital and underwent complete cardiorespiratory monitoring. All changes in Spo2, hemodynamics, serum ferritin and CRP were recorded before the study. Results: This study presented that improved patient had lower ferritin levels than those who were still ill. In addition, prescribing deferoxamine as an adjunct to vitamin C can prevent cytokine storms that was effective for improving the patients with COVID19. Conclusion: In conclusion. According to the role of deferoxamine and vitamin C in significantly reducing inflammatory factors of ferritin and CRP, they can be used as an adjunctive therapy in patients with COVID19.

Obstructive sleep apnea(OSA) is a syndrome characterized by obstruction in the upper airway during sleep. OSA patients undergoing procedures under GA are at increased risk for hypoxemia, pneumonia, difficult intubation, atelactasis, myocardial infarction making it a challenge for anesthesiologist. Retrograde intrarenal surgery(RIRS) is normally performed under GA to prevent respiratory embaracement. There are very few studies focusing on Regional anesthesia in RIRS procedure. A Sixty-three-year-old male known case of morbid obesity (BMI- 35 kg/meter square), OSA (on CPAP support at night) presented with left renal pelvis calculus, STOP BANG score (=5) therefore making it a case of difficult airway. Respiratory discomfort improved at 30-35-degree head up due to existing OSA considering the severe OSA and anticipated difficult airway, the surgery was planned under Lumbar subarachnoid block with preparation for management of difficult airway if conversion to GA required. 3 ml of 0.5 percent Bupivacaine heavy and 25 mcg fentanyl injected into subarachnoid space. T6 level block acheived after 3 minutes. The patient was put on his home CPAP machine with 5cm H2O PEEP. The patient was maintained on sponatneous ventilation and monitored using Etco2 at aliquot of 1mg midazolam given to mimic natural sleep pattern. The surgery was uneventful and the risk of induction of GA and difficult intubation was succesfully avoided. Patient with regional anaesthesia who are prone to converted to GA due to multiple risk factors, i.e., OSA with anticipated difficult airway can create a chaotic situation. So as a preliminary step NIV can be used, and along with it, mild sedation can be supplemented to improve acceptance and to avoid asynchrony. In this case NIV was used as a preemptive ventilation strategy even before actual requirement of BiPAP by mimicing the natural sleep pattern and make patient comfortable while a smooth conductance of the procedure.
阻塞性睡眠呼吸暂停（OSA）是一种以睡眠时上气道阻塞为特征的综合征。在全麻下接受手术的 OSA 患者发生低氧血症、肺炎、插管困难、乳汁淤积、心肌梗死的风险增加，这对麻醉师来说是一个挑战。逆行肾内手术（RIRS）通常在全身麻醉下进行，以防止呼吸道栓塞。很少有研究关注逆行肾内手术中的区域麻醉。一名 63 岁的男性病例已知患有病态肥胖（体重指数- 35 kg/meter square）和 OSA（夜间使用 CPAP 支持），并伴有左肾盂结石，STOP BANG 评分（=5），因此属于困难气道病例。考虑到严重的 OSA 和预期的困难气道，手术计划在腰椎蛛网膜下腔阻滞下进行，并准备在需要转为 GA 时处理困难气道。在蛛网膜下腔注射了 3 毫升 0.5% 的布比卡因和 25 微克芬太尼。3 分钟后达到 T6 级阻滞。患者被安置在家用 CPAP 机上，PEEP 为 5 厘米 H2O。患者保持海绵状通气，并使用等量 1 毫克咪达唑仑进行 Etco2 监测，以模拟自然睡眠模式。手术很顺利，成功避免了诱导 GA 和困难插管的风险。由于多种风险因素（如 OSA 和预期的困难气道），使用区域麻醉的患者很容易转为 GA，这可能会造成混乱局面。因此，作为第一步，可以使用 NIV，同时辅以轻度镇静剂，以提高接受度，避免不同步。在本病例中，即使在实际需要使用 BiPAP 之前，也将 NIV 作为一种先发制人的通气策略，通过模拟自然睡眠模式，使患者在顺利进行手术的同时感到舒适。

Background: Management of patients with high risk of bleeding during oral and dental procedures faces many challenges. The aim of this study was review strategies for facing high risk of bleeding patients taking dabigatran under dental procedure. Methods: Articles and scientific texts will be searched in the six main databases, such as PubMed, Scopus, Web of Science, Science Direct, Google Scholar and Cochrane Library from 2007 to 2022, with keywords “dabigatran” AND “bleeding” AND “dental procedures” OR “dental care”. The inclusion criteria for articles included in the study were papers published about treatment patients with dabigatran and undergoing a dental procedure, English language and design of case reports, case series, quasi-experimental studies and clinical trials. This study was performed using PRISMA. Results: At first, 43 references included and finally 8 articles that met the inclusion criteria were select. CASP and STORBE checklists used for quality evaluation. Two reviewers checked eligibility of the selected articles, separately. Challenging Controversial results were found in selected studies. 4 studies demonstrated that Dabigatran should be interrupted at least 12 hours before invasive dental procedures. Some studies highlight that discontinuing Dabigatran depends on the patient's renal function. Also, it showed that deciding whether to stop Dabigatran or not by cardiologists determine based on elective or emergency high-risk patients. Conclusions: Based on the results of the included studies, it is better to decide to stop or continue dabigatran before any dental treatment based on the type of intervention, the risk of bleeding and the patient's clinical situation. However, is preferred to discontinue taking this drug in high risk of bleeding dental procedures.

Background: The Covid-19 disease was the most significant pandemic of the century. Health care providers showed great sacrifices in managing this disease and saving humanity, and they suffered many injuries. So, this study aimed to investigate the effect of Covid-19 on the resident’s quality of life and comparison with medical students. Methods: This cross-sectional study was performed on 223 Residents and 225 medical students. Using a random sampling method, WHOQOL-BREF 26 questionnaire was distributed among the participants. The collected data were analyzed with SPSS 21 software using T-test and ANCOVA. Results: The results showed that covid-19 had caused a decrease in the quality of life of residents compared to medical students (P value<0.001). In addition, more advanced statistical analyzes showed that high work and study hours, irregular sleep, work history in COVID-19 wards, and the experience of CPR and intubation conditions of covid-19 patients have independent effects on the quality of life. Conclusion: Covid-19 hurt all aspects of the quality of life of residents. Considering the essential role of residents in educational and treatment hospitals, it is necessary to make plans to improve the quality of life and psychological support of these people to prevent the decline in the quality of healthcare services.

Background: Anaesthesiologists face difficult intubation (DI) more frequently in obese patients. Thus, we aimed to test if central obesity indices including hip circumference (HC), neck circumference (NC) or waist circumference (WC) can effectively predict DI and difficult mask ventilation (DMV) in them. Methods: HC, NC, WC, mask ventilation grade, intubation difficulty scale (IDS), history of snoring and obstructive sleep apnoea (OSA) were measured in 300 patients with BMI ≥ 30 kg/m2. Receiver operating characteristic curve (ROC) and multivariate, logistic regression were employed to identify predictors of DI (IDS ≥5) and DMV define as mask ventilation grade of 3 or 4. Results: DI and DMV were, respectively, detected in 14.7% and 12.7% of subjects. According to Multiple logistic regression analysis BMI (Odds ratio (OR):1.17, 95% confidence interval (CI): 1.08-1.28, p<0.001), NC (OR: 1.26, 95% CI: 1.04-1.52, p=0.01), HC (OR:1.06, 95% CI: 1.03-1.10) and HC/NC ratio (OR: 4.9, 95% CI: 1.64-14.92, p= 0.004) considered as independent predictors of DI. The same analysis recognized BMI (OR:1.13, 95% CI: 1.03-1.24, p=0.006), WC (OR: 1.06, 95% CI:1.01-1.11, p=0.01), and HC/BMI ratio (OR=0.18, 95% CI:0.06-0.53, p=0.002) as DMV predictors. Sensitivity of BMI >35.8 kg/m2, NC >39.9 centimetres (cm), HC>118cm and HC/NC ratio >2.9 were determined as 70.5%, 68.2%, and 69.3% respectively for prediction of DI. Sensitivity of BMI >36.6 kg/m2 and WC >118 cm for predicting DMV were identified as 71.0% and 73.6%. Conclusion: This study proposes to simultaneously consider the HC/NC ratio and WC as a predictor of difficult airway in the obese.

Background: Endotracheal intubation is a potentially high-risk aerosol-generating procedure. So, an intubation box (I-Box) is designed for personal protection during intubation. This study aimed to compare the outcomes of endotracheal intubation with and without an I-box in COVID-19 patients. Methods: In this study, 60 COVID-19 patients (30 patients in each group) with and without I-box groups were included. outcomes of intubation including duration of intubation, first-pass success intubation, suitable visibility of airways, restriction of movement in the neck, the need to surface maneuvering of the airway, and the number of attempts for successful intubation were compared between the two groups. Results: The time of intubation was significantly longer in the I-box group (15.27±2.6 seconds) than without the I-box group (8.37±1.3 seconds) (p<0.001). All patients (100%) were intubated in the first attempt in the without I-box group while the rate of first-pass success intubation was 50% in the I-box group (p <0.001). The visibility of the airway was significantly better in the without I-box group than the I-box group (without I-box: 23 patients (76.7%), I-box: 15 patients (50%), p= 0.032). The frequency of need to optimizing maneuver of the airway was in without and with I-box was 23.3% and 50% respectively (p=0.032). Conclusion: However, the I-box as a physical barrier can protect healthcare workers but its use increased the time to intubation and the number of attempts for successful intubation and reduced the rate of first-pass success intubation and visibility.
