Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries
Abstract
Background
Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres.
Methods
This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries.
Results
In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia.
Conclusion
This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries
Coagulopathy during liver transplantation
In this review article, we aimed to mainly review the principles for the management of hemostasis, changes that occur in the hemostatic system, and the techniques to reduce hemorrhage during liver transplantation. Hemostasis is a defense mechanism that may ensue from vascular damage and hemorrhage and consists of multiple phases which involve cellular and humoral elements of coagulation. In the presence of a cause, such as trauma-induced liver injury or hepatic failure that may trigger coagulopathy, the process becomes more problematic, and moreover, severe coagulation disorders may arise in daily practice unless the situation is intervened correctly and on time. During liver transplantation, the implementation of transfusion and coagulation management algorithms based on the point of care tests may reduce blood loss and transfusion requirement. Moreover, antifibrinolytic therapy and a low central venous pressure with restrictive fluid administration reduce bleeding
VivaSight: a new era in the evolution of tracheal tubes
WOS: 000382421800085PubMed ID: 27555208Study objective: To evaluate the available data describing the use of single and double lumen VivaSight tubes. Design: Systematic review. Setting: The use of VivaSight tubes for elective surgeries including advantages, disadvantages, and possible complications. Patients: Systematic review of randomized controlled trials from databases including Medline, Web of Knowledge, Google Scholar, and Cochrane Central Register of Controlled Trials. Interventions: Comparison of VivaSight single and double-lumen tubes with conventional tubes during normal airway and expected difficult airway management. The effectiveness of the devices was also evaluated during 1-lung ventilation for patients undergoing thoracic surgery. Measurements: Intubation time, success rate, the requirement for fiberoptic bronchoscope, and the rate of complications. Main Results: Following a VivaSight double-lumen tube, a flexible bronchoscope is still needed. It is difficult to agree that VivaSight tube reduces the need or use of a bronchoscope. According to the current literature, it is unclear if there is any advantage of the VivaSight compared with using flexible bronchoscopy to direct a blocker into the correct lung. The cost may be another issue. Studies comparing VivaSight tubes with standard double lumen tubes reported faster tracheal intubation rate and higher success rate at first attempt for VivaSight. However, VivaSight tubes may cause soft tissue trauma such as bleeding, hematoma, edema, and erythema. Sore throat and dysphonia are other reported complications. Due to the outer thickness, smaller-sized double-lumen tube may be necessary. It has been reported to have the disadvantages, such as melting due to the heat of light source before insertion and sudden shutdown without warning. Conclusions: Problems such as overheating and melting on the distal end of the tube due to the light source and potential breakdowns of the cable should be solved by the manufacturer. This will probably require a redesign and necessitate further studies. (C) 2016 Elsevier Inc. All rights reserved

Airway management in penetrating thoracic trauma
Penetrating thoracic trauma accounts for 20–25% of all deaths due to trauma in the first four decades of life. About 33% of deaths from thoracic trauma occur due to penetrating trauma. In an autopsy study that enrolled 1178 trauma patients, 82% of the patients with tracheobronchial injuries died at the incidence site. In another study, 30% of those who could be transferred to the hospital died. This review aimed to revisit penetrating thoracic trauma with respect to complications and the strategies for airway management. While the risk of death in injuries with a sharp object is normally 1–8%, it reaches 25–28% when the cardiac box is included, and still, most of the patients are lost before they can come to the hospital. The consequences and management of penetrating thoracic trauma are mainly dependent on the extent of the injury to internal organs, as well as on the skill of the clinicians, airway obstruction, respiratory failure, and bleeding. Chest computed tomography (CT) is better than chest radiography in diagnosing the main bronchus or lobe/segment rupture. However, with the use of multi-channel multi-detector CT, the sensitivity of CT imaging has increased to 94% in the diagnosis of tracheobronchial injuries. While standard orotracheal intubation is sufficient in 75% of the patients, flexible bronchoscopy, intubation through the open wound or tracheostomy is required for airway provision in the rest. Clinical suspicion is the first diagnostic tool in a patient with penetrating airway trauma, and early treatment with multidisciplinary teamwork is life-saving
