Background: Some studies have reported that mouthwashes can decrease the viral load in the mouth, but there is not much information about the effectiveness of mouthwashes on coronavirus disease 2019 (COVID-19). This study was conducted to compare the impact of using two types of mouthwash, chlorhexidine and sodium bicarbonate, on COVID-19 symptoms and infection. Materials and Methods: The present three-group, double-blind clinical trial examined 116 operating room nurses and anesthesia personnel of certain hospitals of Isfahan University of Medical Sciences, Isfahan, Iran. The participants were randomly assigned to three groups: intervention group 1 (chlorhexidine mouthwash), intervention group 2 (sodium bicarbonate mouthwash), and the control group (placebo). Mouthwash was used twice a day (morning and night) for 2 weeks. The participants were monitored in terms of COVID-19--related symptoms for 4 weeks, from the first day of mouthwash use. Results: Fisher's exact test indicated a significant difference between the chlorhexidine and control groups in terms of the onset of COVID-19--related symptoms (p = 0.02). There was no significant difference in the symptoms of COVID-19 between the groups, but the groups were significantly different in terms of all symptoms at a 4-week interval (p = 0.04). Furthermore, headache was less observed in the chlorhexidine (p = 0.007) and sodium bicarbonate (p = 0.03) groups compared to the control group. Conclusions: The use of 0.2% chlorhexidine mouthwash can decrease the onset of COVID-19--related symptoms in health-care workers. In addition, this mouthwash can partially reduce the symptoms of this disease in comparison to the control and sodium bicarbonate groups. [ABSTRACT FROM AUTHOR]

Introduction: According to studies, children are often kept fasting in intervals longer than the standard fasting time, which can lead to complications for them. So, there was little and contradictory evidence about fasting time and its complications, this study aimed to investigate the relationship between preoperative fasting time with vital signs and the type and dose of analgesic in pediatrics. Materials and Methods: In this cross-sectional research, 192 children aged between 6-36 months were surveyed in a specialized center for children. Children were examined through a researcher-made form in terms of preoperative fasting time, the type and dose of analgesic, as well as post-operative respiratory rate, pulse rate, and temperature through observation, pulse oximetry, and tympanic thermometer. Results: The mean fasting time was 8.09 hours. Fasting time was higher in children who took Apotel (P=0.03). The fasting time was significantly and directly related to the dose of Apotel and also to the total dose of the three drugs (P<0.001 and P<0.001, respectively). The mean body temperature of children who fasted for more than six hours was significantly lower than other children (P<0.001). Conclusion: The fasting time of children was more than standard times. Using a higher dose of Apotel and the total higher dose of three analgesic drugs suggests the existence of more pain in patients with longer fasting times. Moreover, increased fasting time led to a decrease in the temperature in pediatric patients. Therefore, it is necessary to reduce the fasting time of children to prevent the complications associated with it. [ABSTRACT FROM AUTHOR]

Background: Operating Rooms (ORs) are complicated environments that necessitate the improvement of OR staff's knowledge and skills to remain clinically competent and secure patient safety. The aim of this study was to assess clinical competence of OR staff in accordance with some related factors. Materials and Methods: This descriptive analytical cross-sectional study was conducted on 227 OR staff in nine academic hospitals. Sampling was performed from the beginning to the end of May 2019 and the samples were selected by quota sampling. Data were collected using a researcher-made questionnaire encompassing six dimensions of competency including general knowledge, specialized knowledge, general practical skills, specific practical skills, personality, and motivation. Data analysis was performed using descriptive and interpretive statistics. Results: The mean (SD) total score of competence was 80.99, which was optimal (11.28). The lowest score was related to the dimension of general practical skills with the mean (SD) score of 53.32 (10.26). The mean score of specialized practical skills was significantly higher in single-specialty ORs (F = 21.53, p < 0.001). Based on multiple linear regression test, it was possible to predict clinical competency through the age and work experience (R-squared = 0.96, beta = 0.31, p = 0.022). Conclusions: Specialized training has overshadowed the general practical skills that are related to the observation of basic principles of patient safety apart from surgical specialization. Strengthening of competence in general practical skills need to be prioritized in empowerment programs. We need a fixed and permanent space for the continuation of educational programs designed to promote perioperative general practical skills. [ABSTRACT FROM AUTHOR]

Introduction: Some countries have implemented reuse of laparoscopic instruments for cost‐effective purposes. An accurate cleaning as the first step of reprocessing would lead to the effective sterilization. The purpose was to evaluate the effect of cleaning guidelines implementation on microbial load of laparoscopic instruments which were used in laparoscopic cholecystectomy surgery. Methods: This experimental study was done in an educational hospital, in 2017 and included a total of 128 laparoscopic instruments randomly selected from cholecystectomy surgeries and divided into two cleaning groups. The instruments were checked out in terms of number (colony‐forming units [CFU]/mL) and type of microorganisms in two groups of routine cleaning and according to guideline cleaning. This guideline was indigenous and taken from successful instruction in this context that was presented by the Association for the Advancement of Medical Instrumentation (AAMI). The appropriate statistical analysis was conducted by SPSS version 19. Results: The average microbial load was 2.4 × 106 CFU/100 mL after clinical use. It was reduced to 7.2 × 105 CFU/100 mL in the control group and 3.4 × 104 CFU/100 mL in the intervention group, after the cleaning process. The most common microorganisms that were isolated immediately after clinical use were Escherichia coli 81.2%, Pseudomonas 68.8%, Klebsiella 57.8%, and spp., and so on. Conclusion: The AAMI cleaning method is recommended to be utilized by operating room nurses for laparoscopic instruments. [ABSTRACT FROM AUTHOR]

Background: The aim of this study was to compare the PID with bare skin (without PID) regarding bacterial recolonization and bacterial regrowth of the adjacent skin of surgical incision in lumbar spine surgery patients. Methods: This quasi-experimental study was conducted from February to May 2018 on 88 patients who were candidate for lumbar spine surgery. Patients were assigned to one of two groups, treatment (with PID) and control (without PID). Skin sampling (adjacent of surgical incision) for bacterial culture was done in two steps, immediately after surgical skin prep (IASSP) and immediately after surgical wound closure (IASWC) by researcher. Finally, samples were sent to the laboratory. Results: The mean total bacterial count of patient's skin in stage IASSP was not significantly different between treatment and control groups (0.34 vs 0.27, P = 0.68). However, mean total bacterial count in stage IASWC in treatment group was significantly higher than control group (2.2 vs 0.93, P = 0.03). The frequency distribution of S. aureus (P = 0.04) and S. epidermidis (P = 0.02) was significantly higher in treatment group compared with control group in stage IASWC. Conclusions: The results showed that using PID is unable to reduce recolonization and regrowth of bacteria on patients' skin adjacent to surgical wound in clean lumbar spine surgeries. However, making a definite decision about using or not using of PID requires further studies. [ABSTRACT FROM AUTHOR]

Background: One of the factors affecting the behavior and performance of nurses is mental workload. Training programs can improve the attitude, knowledge, and performance of nurses. However, the impact of these programs on mental workload is not clear. Therefore, the study aimed to evaluate and compare the effect of two conventional and self-designed education classes on the mental workload of neonatal intensive care unit (NICU) nurses. Materials and Methods: This study was conducted on 68 nurses, divided into two intervention and control groups. Subjects of the intervention group attended a social awareness reinforcement class, in which one of the dimensions of emotional intelligence was introduced and covered. Research tool was the mental workload questionnaire of National Aeronautics and Space Administration Task Load Index (NASA-TLX). Results: In this research, results of the paired t-test were indicative of a significant decrease in the mean score of mental workload immediately after the intervention (t = 1.48, p < 0.001) and one month later (t = 1.11, p = 0.007). Moreover, a significant difference was observed in the mean score of mental workload of the intervention group between before and after the conventional education class, and before and 1 month after the self-designed class using repeated-measures analysis of variance (F = 21.31, p < 0.001). Conclusions: According to the results of the study, the conventional education class had no impact on the mental workload, whereas the self-designed class significantly decreased mental workload. Therefore, it is suggested that education programs be conducted for NICU nurses to improve their emotional intelligence, which leads to decreased level of mental workload. [ABSTRACT FROM AUTHOR]

OBJECTIVES: High-frequency jet ventilation (HFJV) is a convenient method for providing ventilation during fiberoptic bronchoscopy. We describe an incipient approach of high-frequency jet ventilation via the working channel of a flexible bronchoscope for nonintubated patients who suffer from hypoxemia during bronchoscopy. The aim of this study was to test the efficacy of this incipient approach and determine the possible complications related to it. MATERIALS AND METHODS: Sixteen patients who had oxygen saturation below 70% that did not resolve with nasal oxygen for 20 s during interventional bronchoscopy were included in the study. High-frequency jet ventilation was administrated via the working channel of a bronchoscope for 3 min. Arterial blood gas circumscriptions were compared before and after jet ventilation. RESULTS: Oxygen saturation increased to >90% in all patients 30 s after jet ventilation. Mean arterial oxygen saturation pressure increased from 54.84 to 111.98 mmHg with jet ventilation (p=0.0001). Arterial carbon dioxide tension decreased after jet ventilation. The body mass index had no consequential effect on arterial carbon dioxide pressure after jet ventilation in our patients (p=0.1). Complications such as pneumothorax and working channel damage were not observed. CONCLUSION: High-frequency jet ventilation via the working channel of the bronchoscope is a novel method that can provide optimal ventilation with minimal complications to nonintubated patients suffering from hypoxemia during bronchoscopy. This method also reduces the duration of bronchoscopy procedures. [ABSTRACT FROM AUTHOR]

Introduction: By adhering to care standards, many adverse outcomes for patients, such as pressure injuries, tissue necrosis and patient falls, can be prevented. The aim of this study was to investigate the level of compliance with care standards before, during and after various types of bariatric surgeries., Materials and Methods: This study was a cross-sectional descriptive study conducted in the operating theatres of selected teaching hospitals in Isfahan (Iran). The study sample consisted of all operating theatre personnel in the selected teaching hospitals who met the inclusion criteria. Compliance with care standards was measured using a researcher-developed checklist. A researcher-developed questionnaire with 43 true/false questions was used to evaluate the operating theatre personnel's professional knowledge. The data were analysed using SPSS version 20 and descriptive and inferential statistics., Results: The mean score of adherence to care standards and the mean score of professional knowledge of operating theatre personnel regarding care of laparoscopic bariatric surgery were 78.35 ± 9.49 and 29.45 ± 6.17, respectively. There is no significant relationship between these two variables, with a two-tailed significance (Sig.) of 0.056 and a correlation coefficient (r) of 0.199., Discussion and Conclusion: In general, it can be concluded that the specific knowledge of the local operating theatre personnel regarding minimally invasive laparoscopic surgery care is at an intermediate level. Requirements for training in this area were therefore successfully identified. In addition, not all operating theatre personnel adhere to the standards of care for patients undergoing laparoscopic bariatric surgery. This non-adherence could be due to insufficient training or the absence of established standards in hospitals., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship and/or publication of this article.

Background: The aim of this study was to investigate the effect of the incise drape (ID) on surgical wound bacterial contamination during lumbar spine surgical procedures in treatment group (with ID) and control group (without ID)., Materials and Methods: The present study was conducted on 88 patients who were a candidate for lumbar spine surgery. The patients were randomly assigned to one of the two groups, treatment and control. The ID was only used in the treatment group. The surgical wound sampling for bacterial culture was done in two steps, immediately after surgical incision (IASI) and immediately prior to the surgical wound closure (IPSWC). The samples were then sent to the laboratory., Results: The mean total bacterial count of the surgical wound in the stage IASI was not significantly different between treatment and control groups (0.09 vs. 0.02, P = 0.31). However, this means in the stage IPSWC in treatment group was significantly more than the control group (18.6 vs. 0.41, P = 0.04). The frequency distribution of Staphylococcus aureus (25% vs. 3%, P = 0.02) and Staphylococcus epidermidis (36.4% vs. 9.1%, P = 0.002) was significantly higher in the treatment group compared with control group in the stage IPSWC., Conclusion: The results suggest that the use of ID is unable to reduce surgical wound bacterial contamination in clean lumbar spine surgery. Therefore, based on the results obtained in our study, the application of ID is not recommended as an essential action for the prevention of surgical wound contamination., Competing Interests: There are no conflicts of interest.

Background: Education is based upon the knowledge, skills, and attitudes that are required for an occupation, and the changes occurring in the occupations and duties as well as in the ideals and values necessitate constant needs analysis. Furthermore, owing to the transformations in sciences, especially medical sciences, the current syllabus for the operation room courses at associate level will not meet the requirements for operation room personnel in future. Therefore, the syllabus for operation room B.S. was developed and proposed in a research project entitled "Study of the international syllabus for the operation room courses and proposing an appropriate syllabus for the courses in Iran." Since the operation room courses at B.S. level are supposed to be introduced in Iranian universities, we intended to learn about the opinions of other people related to this subject in Iran., Methods: In this research, a questionnaire was used that contained the syllabus proposed for the operation room B.S. courses, which was the result of a research project entitled "Study of the international syllabus for the operation room courses and proposing an appropriate syllabus for the courses in Iran." To develop this syllabus, 12 heads of the operation room departments in universities across Iran in which the subject matter was being taught at associate level were consulted., Results: The study showed that 14 out of the 53 courses proposed in the syllabus had a desirability level of 100%, 22 courses were desirable at levels of 91-100%, 19 were 75-90% desirable, and no courses had a desirability level less than 75%. After carrying out some modifications to the syllabus, the problems were resolved and the opinions were again asked. When a consensus of greater than 70% was reached, the syllabus for the operation room courses at B.S. level was finalized and proposed. The regulations from the Development, Planning, and Evaluation Office of the Ministry of Health were also followed., Conclusions: Although all the courses showed a desirability level of greater than 70%, receiving appropriate suggestions about some courses led the research team to carry out major or minor modifications to some of the courses.
