“…The size of the particles created varies between devices [3,4]. A number of reports have described the contents of surgical smoke as airway irritants, mutagens, and a potential vehicle for the spread of malignancies or infection [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. While OR air filtering and exchange systems do exist, many feel these are inadequate and additional smoke evacuation devices have been introduced.…”

Objectives: To measure changes in air quality during surgery.Methods: Operating room (OR) and hallway air quality was continuously monitored over a 3-month period. Rooftop monitoring was used to control for environmental changes and to account for the infiltration of outdoor air pollutants. Air quality measurements were correlated with operative times and electro-dissection equipment used.Results: OR air is cooler and drier compared to the adjacent hallway. Volatile organic compounds and other gases are below indoor air exposure limit guidelines. Lasers create greater 2.5 μm particulate matter (PM 2.5 ) mass concentration, and greater fine and coarse particle number than cautery or cold tissue dissection. Cautery produces more ultrafine particles (UFP) than other dissection techniques. OR air has lower particle counts than outdoor environmental air by virtue of air conditioning HEPA filtration. Conclusion:Compared to the outside air, operating room air has lower particle counts. Lasers produce higher concentrations of PM 2.5 mass and, fine and coarse particle number counts. Cautery produces higher concentrations of UFP number counts than other modalities and warrants consideration of the use of masks with ultrafine particle filtration capacity. Operating room air is consistently cooler with decreased humidity, which may cause airway irritation.

“…Increased concern has been raised regarding the health effects of surgical smoke on OR personnel [2,[5][6][7][8][9][10][11][12][13][14][15][16]. Small particles carry chemical risks and larger particles have infectivity potential [3,4,10].…”

The combined modality treatment of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) has gained worldwide acceptance for management of selected patients with peritoneal metastases from various cancers. Cytoreductive surgery is performed with the goal of removing all macroscopic disease and is coupled with perioperative chemotherapy (POC) in the form of HIPEC with or without EPIC (early postoperative intraperitoneal chemotherapy) to deal with the microscopic residual disease. These treatments entail the use of cytotoxic drugs in the operation theatre or in the intensive care unit where they are not commonly used and put the healthcare workers participating in the treatment at risk of exposure. CRS is performed with high voltage electrocautery generating a large amount of surgical smoke which is inhaled by the involved personnel and has potential health hazards. This article outlines the safety measures to be taken while performing CRS and POC.

Abstract.In minimally invasive surgery, deployment of motion compensation, dynamic active constraints and adaptive intra-operative guidance require accurate estimation of deforming tissue in 3D. To this end, the use of vision-based techniques is advantageous in that it does not require the integration of additional hardware to the existing surgical settings.Deformation can be recovered by tracking features on the surface of the tissue. Existing methods are mostly based on ad hoc machine vision techniques that have generally been developed for rigid scenes or use pre-determined models with parameters fine tuned to specific surgical settings. In this work, we propose a novel tracking technique based on a context specific feature descriptor. The descriptor can adapt to its surroundings and identify the most discriminate information for tracking. The feature descriptor is represented as a decision tree and the tracking process is formulated as a classification problem for which log likelihood ratios are used to improve classifier training. A recursive tracking algorithm is used to obtain examples of tissue deformation used to train the classifier. Additional training data is generated by geometric and appearance modeling. Experimental results have shown that the proposed context specific descriptor is robust to drift, occlusion, and changes in orientation and scale. The performance of the algorithm is compared with existing tracking algorithms and validated with both simulated and in vivo datasets.
