Operating room black box:Scrutinizer of theatre practices

Objective:Adverse surgical events are a major cause of morbidity,mortality,and disability worldw ide.The cause of many such events can be attributed to interruptions in the operating room(OR),muli-tasking by surgeons,etc.The objective of this study was to observe the types and frequency of intra-operative wor kflow interruptions in our ORs.Method:This ccoss-sectional study was conducted from March Do April of 2023.An observational approach using an audio-video recording device was employed to record OR flow disr uptions.One elective OR and one emergency OR under the Department of General Surgery were selected for the study.All open and laparoscopic surger ies conducted in the selected ORs were included.An Internet Protocol camera'was installed in the selec ted ORS with a view of the entire room,including the anesthesia station.Audio-video recording was started after the first indsion and stopped after closure of the surgical site.Result:Of the 51 cases that were studied,45(88.2%)were elective,and 18(35.3%)were laparoscopic cases.They could be classified into 8 types of open procedures and 4 types of lapar oscopic procedures.The mean maximum headcount inside the OR was 15.5土3.6 and doors opened on average of 15.8土6.0 times during a procedure.Other interruptions were surgeons attending phone calls(24,47.1%),leaving the sterile area(21,41.2%),technical disturbances(32,62.7%),anesthetic interruptions(18,35.3%),and faulty instruments(29,56.9%)Elective procedures had a signifcandy higher average number of in-terruptions per operating hour than emergency procedures(175±8.6vs.7.1±2.9,p<0.01).Condusion:Preventable factors such as faulty instruments,anesthetic interruption,and attending phone calls by the surgeon are commonly observed in ORs.They need to be addressed by timely surgical audits or the adoption of continued sureillance methods that can help take measures to minimize their occurrence.

Large carotid body tumor successfully resected in hybrid operating theatre: A case report

BACKGROUND Surgical treatment for large carotid body tumor (CBT),particularly the Shamblin III type,is challenging and rarely reported.CASE SUMMARY In July 2014,a 63-year-old woman presented to our hospital with a large CBT (130 mm × 60 mm × 70 mm).The lesion was hypervascular,spanned from the first to the seventh cervical vertebra,and adhered to the right common carotid artery (CCA),internal carotid artery (ICA) and external carotid artery (ECA).The resection was carried out in a hybrid operating theatre.First,we used Onyx gel to embolize the feeding artery.An ICA balloon was used to prevent gel entry into the ICA.After shrinkage and hardening of the CBT,we quickly resected the CBT as well as a part of the ECA that adhered to the CBT.A vascular shunt was inserted between CCA and ICA,and the part where the ICA was cut off from the CCA was directly sutured.A follow-up at four years later showed no neurological damage.CONCLUSION For large hypervascular CBT,embolization of the feeding artery prior to resection is helpful.The hybrid operating theatre is the ideal platform to carry out such operations.

Indoor Air Quality in a Real Operating Theatre under Effective Use Conditions

The aim of this study is to investigate the impact of surgical staff on the indoor air quality in a uni-directional ventilation Operating Theatre (OT). Experimental measurements of particles and microclimate were acquired at rest and in operational conditions. The real OT (operational) use was simulated by a sham hip arthroplasty. CFD simulations were carried out outlining the studied environment used for experimental measurement campaign. A standard k-ε closure scheme based on RANS equations was implemented to solve the velocity and pressure field using an eddy viscosity approach. Temperature and relative humidity distributions were also computed keeping into account sensible and latent heat sources inside the OT. An Euler-based approach was applied to solve the concentration fields of gaseous contaminant and small particles (up to 5 μm in diameter) in the indoor air. An innovative strategy is proposed to estimate, by an iterative comparison between experimental data and numerical results, the emission rate of particles (differentiated by diameters) released by the occupants to be considered as source terms in the numerical model. Compliance with literature evidence concerning thermal and velocity fields and CO2 concentration was confirmed. From our analyses, some IAQ indexes were deduced, allowing monitoring of the local and overall OT air quality level supplied by the ventilating system during real operational conditions. The highest values of microbial air contamination were recorded during surgical activity;nevertheless, results showed the suitability of the ventilation system in providing the expected air quality.

Aesthetic Processing for Theatre Translation

Theatre translation is one of the most neglected areas in the field of translation.Theatre is a special member of the literature family in that it doubles as a branch of the performing art.It follows that the aesthetic constitutions of a dramatic creation is a complex problem. It is the translator's duty to grasp the artistic features of the literary creation and reproduce them in the version since the most important thing in a piece of literature is its artistic features.

Patients' preferred mode of travel to the orthopaedic theatre

AIM: To determine the preferred mode of travel to the operating theatre for elective orthopaedic patients. METHODS: Data was collected prospectively over a 2-wk period at an elective Orthopaedic Treatment Centre. Patients were asked to complete a patient satisfaction questionnaire following their surgery on their experience and subsequent preferred mode of transport to theatre. The data was then recorded in a tabulated format and analysed with percentages. Fisher's exact test was used to determine if there was any statistical association between patients' preference to walk and various groups; in-patient or day case procedures, and whether patients were < 60 years or > 60 years of age.RESULTS: Seventy patients(40 females and 30 males) fully completed the questionnaire. In total there were 33 d-cases and 37 in-patients. The spectrum of orthopaedic sub-specialties included was knee(41%), hip(17%), foot and ankle(24%), spine(13%) and upper limb(4%). Patient satisfaction for overall experience of travelling to theatre was either excellent(77%) or good(23%). Following their experience of travelling to theatre, 87%(95%CI: 79%-95%) of the total cohort would have preferred to walk to the operating theatre. There was a statistically significant association(P = 0.003) between patients' preference to walk and whether they were daycase or in-patients. Similarly, there was a statistically significance association(P = 0.028) between patients' preference to walk and whether they were < 60 years or > 60 years of age.CONCLUSION: This study confirms the majority of Orthopaedic elective patients would prefer to walk to theatre, when given the choice and if practically possible.

New Perspective of Architectural Design Based on Immersive Theatre Thinking: A Case Study of Rural Living Room Design in Majia Marsh

The new urbanization provides opportunities for the ecological protection of traditional regional culture. In the context of the integrated development of agriculture, tourism, and cultural industries, this paper integrates the thinking of "immersive theatre" and adopts the design method of multithread dramatic narrative mode to create a number of interactive flow lines in the architecture and focus on the sensory experiences of environment, enabling the traditional regional culture to really touch the audience.

Numerical Investigation of Different Airflow Schemes in a Real Operating Theatre

A study on performances of different ventilation schemes provided by vertical and horizontal uni-directional air flow was carried out in a standard orthopaedic operating theatre (OT). Starting from our previous studies of a real OT under operating use conditions, in this research different air flow configurations, considering some air curtain solutions on the ceiling and at the sliding door always assumed to be open as a basic boundary condition, were investigated by numerical simulations. Indoor air quality (IAQ) indexes and thermal comfort parameters, deduced from simulation results were calculated and discussed referring to the best performance and efficacy between the air flow schemes to contrast the incorrect use conditions of the OT. Referring to the studied schemes, the reciprocal comparison emphasizes that a successful outcome in preventing surgical site infection can depend as much on resolving human factors (i.e. operational use conditions, door opening/closing), as on overcoming physical and technical obstacles.

Analysis of the Concept and the Drama Psychology of Immersive Theatre

Immersive theatre means put audience into the space where the story take place.Actors and actresses perform in the authentic environment and audience also in this environment,watching the peoceeding of the story closely.With the success of Sleep No More,more and more people pay attention to immersive theatre.Some Chinese theatre directors also launch out into doing similar things.It is no doubt that immersive theatre is popular now at home and abroad.However,as a new form of theatre,immersive theatre theoretical study is really inadequate.This text aims explain the connotation and concepts of immersive theatre or what is immersive theatre,the feature of immersive theatre in addition to its present situation in China,though Sleep No More,one of the most famous immersive theatres.I hope to offer reference for Chinese theatre people,make contributions for their study and creations,then again filling in gaps in immersive theatre theory.Only in this way,can immersive theatre develop healthily and can its ecology be constructed well.

Headaches Associated with N95 Mask Usage amongst Healthcare Workers in Operating Theatres during COVID-19 Pandemic: A Cross-Sectional Study

Introduction: N95 respirator masks are a cornerstone in the fight against the ongoing COVID-19 pandemic. However, its use has side effects such as headaches. The primary aim of this study is to identify factors that may contribute to higher occurrences of headaches with wearing N95 masks. Methods: A cross-sectional study was conducted across healthcare providers in operating theatres of a tertiary hospital based in Singapore involved in the care of COVID-19 patients. The study involved a self-administered online questionnaire completed by all participants. Results: 176 participants were included into the study, of which 65 (36.9%) reported headaches associated with wearing N95 masks. Out of the 65 participants who experienced headaches, 28 (43.1%) reported experiencing “mild” headache, 30 (46.2%) reported experiencing “moderate” headache, and 7 (10.7%) reported experiencing “severe” headache. 44 participants (67.7%) reported that the headache has affected their work, and 20 participants (30.8%) required analgesia to relieve the headaches. Other symptoms associated with N95 mask usage include skin damage (12.3%), breathlessness (15.4%), giddiness (6.2%), nausea (6.2%) and ear pain (3.1%). Multivariate logistic regression analysis showed that participants younger than 32 years old (p = 0.001) and history of pre-existing headache disorders (p = 0.001) were associated with higher occurrences of headaches with wearing N95 masks. Conclusion: Our study showed that younger age and history of pre-existing headache disorders contribute to higher occurrences of headaches with N95 mask usage. These associations could be useful in identifying at-risk individuals so that precautions may be taken to reduce the occurrence of headaches when wearing N95 masks.

The Redemptive Power of Theatre and the Pursuit of Justice in Our Country’s Good

This paper aims to understand Timberlake Wertenbaker’s Our Country’s Good in the context of theatre in crisis in the 1980s Britain and attempts to find the contemporary resonance of this history play. Through exploring the adaptation and workshop of the play, discussing the transformative influence of rehearsals on the convicts in the Australian penal colony, and expounding on theatre as an important venue for rehabilitation and justice in contemporary society, the paper intends to disclose the playwright’s commitment to theatre, her reassertion of the social role of theatre in contemporary Britain and her critique of Mrs. Thatcher’s philistinism which impaired art, particularly theatre, to a great degree.

Humour in Surrealist Theatre

Surrealist playwrights of the twentieth century use black humour in order to express their discontent towards the society in which they live.Parody of everyday life is a way of reaction against the extensive lifestyle.The actions,the choices and the situations,in which the characters of the surrealist dramas are involved,are comic and grotesque.Surrealist dramas reject the rules of the Western theatre;the lack of plot,the absurd,the misunderstanding,the use of poetic symbols,the parody of bourgeois life,the unexpected reactions and the unreasonable behaviour of the characters are some of the factors that cause laughter and surprise the audience.In this paper we will try to reveal the humour that emerges through the surrealist plays of AndréBreton,Philippe Soupault,Louis Aragon and Roger Vitrac.We will also attempt to highlight the key points through which surrealism in theatre uses black humour in an effort to cover the deep melancholy and pessimistic mood of surrealist dramatists.The questions arising are;in which ways is humour a way of revolution?How can humour include dreams,ingenuity and fantasy?

When Pupils Go to Theatre:The Activation of Memory and the Mnemonic Depiction

Going to theatre,may be a unique experience for schoolchildren,which is indelibly etched in their memory.The Primary School pupil-spectator comes in touch with the theatre principles and is initiated in its world.S/he experiences its ritual and cohesively structured character within the frame of the collectivity that is required and with the particularity of the formation of the psychic mechanism and social conscience in this specific phase of the development of his/her personality,as well as the influence of a number of some other differentiating factors,thus leading to the establishment of a very special relation and interaction between the stage and the audience.S/he also focuses on the elements of the performance that attract his/her interest,are closer to his/her mentality,and challenge his/her attention and emotional stimulation.In this way,the mnemonic recording is activated.The theatre performance consists of a very rich environment for mnemonic traces because of its wealth of codes,their multiple combinations,and variety of functions.The actors’speech,the intense content of ideas and principles in combination with the challenging audio-visual stimuli of the secondary codes of the performance,the plot dynamics,and the director’s techniques and practices,are elements that may initiate mnemonic recording.It is important on the other hand that the school invests in cultural activities such as the attendance of a theatre performance and includes them in the school curriculum.The teacher,as the best advocate of cultural education,the active mediator and coordinator of this visit,undertakes a large part of the responsibility for its successful and indelible mnemonic recording—from the difficult part of the selection of a performance to the care of the suitable conditions for the reception of the spectacle—thus creating the appropriate frame for the pupils to experience the acting event as a means of interaction,play,learning,communication and above all of the activation of the old and the creation of new memories.Therefore,the research interest of the present study focuses on the analysis of all the elements mentioned above,with the aim to examine and analyze the specific factors that influence the mnemonic recordings of the school audience.

Internationalisation and the Development of Vietnamese Theatre

Dinh Thi Nguyen,Director of the Hanoi Academy of Theatre and Cinema,introduces his theory of Internationalisation in Vietnamese theatre.He suggests that traditional performance forms are always being intermingled with foreign performance forms,with intercultural mixing of forms creating“internationalisation”.In this paper the development of Vietnamese theatre forms are examined through the lens of internationalisation.Starting with Cheo and Tuong,this paper follows the ways in which adaptations and absorption of introduced forms of theatre have shaped traditional forms developing into the contemporary theatre practices seen today in modern Vietnam.

Video,Internet and Metaverse:The Media Transitions of Interaction in Theatre

The integration of theatre art with media such as video,the Internet and metaverse embodies intermediality and shows interactivity characteristics.Video is the first to open the possibility of interaction between performers and stage space in the theatre,thus greatly expanding the relationship between people and video in the links of environment,atmosphere,narrative,action and conflict,making stage performance more flexible and changeable.The rapid rise of computer technology represented by the Internet provides two interactive modes of node structure and natural language for digital theatre performance,opening the path for the audience to participate in theatre interaction.The metaverse media environment represented by video games and virtual reality has dramatically changed the freedom of audience participation in theatre.“Digital embodiment”enables the audience to immerse themselves in virtual theatre performance and become a part of theatre composition,thus bringing unprecedented performance experience.

Zhengy Temple Theatre:Beijing's Oldest Peking Opera Theatre

In a small, deep alley right outside Hepingmen (the Peace Gate), no more than one mile south of the Tian’anmen Square, there stands a Peking opera theatre of great antiquity named Zhengyi Temple Theatre. Built over 300 years ago, it is the sole ancient wooden theatre architecture in the world. There are also six other extant theatres with a similar scale, but Zhenyi Temple Theatre is the oldest. It is generally recognized as a living fossil and milestone in the history of Chinese theatres and often cited as an important

谈cinema和theatre

人所共知,电影院(cinema)和戏院(theatre)在英语上是有严格区分的。电影院只能放映电影(film),而戏院(也称剧院)则用来演戏(play)。就词源而言,theatre是一个历史悠久的词,cinema则是近数年才出现的新词。在西方国家中,特别是英国,对theatre的座位的阶层和等第是非常讲究的。戏院通常分成八个部分,名称如下:

Filtered-beam-search-based approach for operating theatre scheduling

To improve the efficiency of operating rooms,reduce the hospital's costs and improve the level of service qualities,a scheduling method is presented based on a filtered-beam-search-based algorithm.Firstly,a scheduling problem domain is described.Mathematical programming models are also set up with an objective function of minimizing related costs of the system.On the basis of the descriptions mentioned above,a solving policy of generating feasible scheduling solutions is established.Combining with the specific constraints of operation theatres,a filtered-beam-search-based algorithm is put forward to solve scheduling problems.Finally,simulation experiments are designed.The performance of the proposed algorithm is evaluated and compared with that of other approaches through simulations.Results indicate that the proposed algorithm can reduce costs,and are of practicality and effectiveness.
