Bibliometrics evaluates the scientific publications in different fields from different aspects. However, the bibliometric state of global research publications on Laryngeal Mask Airway (LMA), as a main progressive medical field, is unknown.

This study aimed to conduct a bibliometric analysis and scientific visualization for inspecting some main bibliometric indicators of the research publications in the field.

This study is a descriptive cross-sectional applied study that used bibliometric techniques. MeSH-retrieved synonyms for LMA were searched in Scopus and the bibliometric indicators of retrieved papers in the field were measured and visualized in Excel and VOSviewer.

In total, 9,783 papers were published on LMA during 1952-2021, starting from one paper in1952 and amounted to 255 in 2021. With ups and downs in the annual publication growth, steady trend was seen in the growth coefficient of publications (R²=.1652). The first to third ranks in publishing countries belonged to the United States with 1,783 papers (18.22%), the United Kingdom with 1,632 papers (16.68%) and Japan with 729 papers (7.45%), respectively. Among active research institutes, Cairns Hospital from Australia ranked first with publishing 284 papers, followed by the University of Queenslandagain from Australia with publishing 141 papers and Royal United Hospital from England with 117 published papers, respectively. Anaesthesia ranked first highly-publishing journal with 1,049 published papers, followed by Anesthesia and Analgesia with 487 published papers and Pediatric Anaesthesia with 448 published documents. Anaesthesia was the main cited source, too. The top three highly-frequent keywords were laryngeal mask airway (N=223), equipment (N=132) and airway management (N=116), respectively. Co-occurred keywords were in four subject clusters.

This study is the first to give a relatively comprehensive bibliometric analysis and visualization of the global research publication and a guide for researchers and research policy-makers in LMA, as a progressive medical discipline.

The professional ethics is the integral part of all dimensions of providing health care services. In recent years, promotion of the professional ethics among medical sciences students becomes very important particularly the ones which are directly in contact with patients. This study aimed to define the relationship between clinical experiences of the operating theater students and the level of adherence to professional ethics.

The descriptive-analytical study was carried out among 87 undergraduate students of operating theater. The sampling was done by census and included all of the 4th, 6th and 8th semester undergraduate students of operating theater which met the criteria to involve in the study. The data were collected by the standard questionnaire of professional ethics and the demographic information questionnaire. Then, they were analyzed by SPSS software version 21.

87 students were participated in this descriptive-analytical study. 35 of them were men (40.2%) and 51 of them were women (58.6%). In this research, the average age was estimated as 22.51 years. The results indicated that there was a significant relationship between the semester, and as its consequence, the clinical experience of the students and professional ethics (p = 0.011). The results also showed the significant relationship between age and professional ethics (p = 0.020).There was no relationship between ethnicity, average mark, sex and professional ethics.

The results of this study showed that increasing students clinical experience and their involvement with issues and problems in OR along with theoretical and practical training in the clinical environment enhance the level of professional ethics among students and later as staff in the clinical environment.

Hospital personnel are exposed to anesthetic gases in various parts of health centers such as operating rooms and recovery rooms. Exposure to anesthetic gases can have serious effects on a personchr('39')s physical and mental health. The purpose of this study was to investigate the effect of demographic variables on the prevalence of neurotoxic symptoms in operating room personnel.

This was a cross-sectional study. Participants included 404 operating room personnel in western Iran. Euroquest questionnaire and demographic checklist were used for data collection. Data were analyzed by t-test, ANOVA and Pearson correlation at the significant level of 0.05.

The results of this study showed that the rate of neurotoxic symptoms in men was more than women and this difference was statistically significant but there was no significant difference between single and married employees and morning work and turnover in neurotoxic symptoms. Also, there was no significant correlation between age and experience of the subjects with neurotoxic symptoms.

Symptoms were higher in some demographic groups, so it is recommended to use appropriate training programs or management techniques such as job rotation in operating room personnel.

With respect to this fact that trust in supervisor could result in positive organizational consequences, the goal of this research was to investigate the relationship between psychological capital, perceived interactional justice and supervisor support with trust in supervisor.

The study design was descriptive and correlational. The statistical sample (250) was all nurses that work in Hamadan hospitals and selected by simple random sampling. The research tools included psychological capital questionnaire, interactional justice questionnaire, supervisor support and trust in supervisor questionnaire. Data were analyzed using Pearson correlation coefficient in SPSS v.19 with significance set at p ≤0.05.

The results showed that there is significant positive relationship between psychological capital and perceived interactional justice with trust to supervisor (p=0.01), but there is not significant relationship between supervisor support and trust to supervisor (p>0.05).

The results indicate that the dimensions of psychological capital, perception of justice, and supervisor support can build trust in the supervisor. Therefore, it is recommended to pay attention to the variables mentioned in order to build trust in the supervisor.
