There are many occupational risk factors in operating room work. Polymethyl methacrylate (PMMA) , as a kind of common bone filling and repairing material, is widely used in the fixation of artificial joints, oral braces and orthopedic prosthesis. However, PMMA will release methyl methacrylate (MMA) monomer when it is implanted into human tissues and polymerized to harden, which is toxic to the body. This paper analyzes harmful factors in using PMMA bone cement, and then explores corresponding occupational protection knowledge, in order to reduce the occurrence of occupational hazards related to PMMA bone cement and enhance the self-protection ability of the operation room medical staff.

OBJECTIVE: To compare the completion time of endotracheal intubation and laryngeal mask implantation in operating room and on slope of ski resort, and to discuss the optimal method of estab-lishing artificial airway on slope of ski resort. METHODS: The simulator was placed with the head under the feet on slope of ski resort. The artificial airway was established by tracheal intubation assisted by video laryngoscope (endotracheal intubation group) and laryngeal mask placement (laryngeal mask group) respectively by an anesthesiologist who wore full set of ski suits, helmets, goggles, gloves and ski boots. Each method was repeated 5 times, and the operation time of artificial airway establishment was recorded. While the simulated human was placed flat on the operating table in an operating room of a hospital, and the artificial airway was established by the same anesthesiologist using the same methods. Time was recorded and repeated for 5 times. The completion time of endotracheal intubation and laryngeal mask placement in the operating room and on the ski slope were compared. RESULTS: The operating time of tracheal intubation in the operating room was longer than that of laryngeal mask placement [(79.8±10.4) s vs. (53.4±2.7) s, P=0.005], and the operating time of endotracheal intubation on the ski slope was longer than that of laryngeal mask placement [(209.2±32.7) s vs. (72.2±3.1) s, P=0.001]. The time of endotracheal intubation group on the slope of the ski resort was longer than that in the opera-ting room(t=-7.851, P=0.001). The time of laryngeal mask group on the slope was longer than that in the operating room (t=-19.391, P < 0.001). CONCLUSION On ski slope, both of tracheal intubation assisted by video laryngoscope and laryngeal mask placement can quickly complete the establishment of artificial airway, but the time required is longer than that in the operating room. The time of laryngeal mask placement to establish artificial airway is shorter than that of tracheal intubation assisted video laryngoscope, which may have a certain advantage in ski rescue.

OBJECTIVE: To investigate the baseline levels of microorganisms' growth on the hands of anesthesiologists and in the anesthesia environment at a cancer hospital. METHODS: This study performed in nine operating rooms and among 25 anesthesiologists at a cancer hospital. Sampling of the hands of anesthesiologists and the anesthesia environment was performed at a ready-to-use operating room before patient contact began and after decontamination. RESULTS: Microorganisms' growth results showed that 20% (5/25) of anesthesiologists' hands carried microorganisms (> 10 CFU/cm ²) before patient contact began. Female anesthesiologists performed hand hygiene better than did their male counterparts, with fewer CFUs ( P = 0.0069) and fewer species ( P = 0.0202). Our study also found that 55.6% (5/9) of ready-to-use operating rooms carried microorganisms (> 5 CFU/cm ²). Microorganisms regrowth began quickly (1 hour) after disinfection, and increased gradually over time, reaching the threshold at 4 hours after disinfection. Staphylococcus aureus was isolated from the hands of 20% (5/25) of anesthesiologists and 33.3% (3/9) of operating rooms. CONCLUSION Our study indicates that male anesthesiologists need to pay more attention to the standard operating procedures and effect evaluation of hand hygiene, daily cleaning rate of the operating room may be insufficient, and we would suggest that there should be a repeat cleaning every four hours.

Objective To construct a nursing quality index system for the assisted reproduction hospitals integrating outpatient department,wards,and operating rooms and provide a reference for the application of the system in the quality control of clinical reproductive care. Method On the basis of Donabedian's health care quality model of structure-process-outcome,we established a nursing quality index system for assisted reproduction hospitals via literature retrieval,semi-structured interviews,Delphi method,and analytic hierarchy process. Results The two rounds of expert's questionnaire survey demonstrated the response rates of 100% and 92%,the expert authority coefficients of 0.911 and 0.919,and the Kendall coefficients of concordance of 0.228 and 0.253,respectively (all P<0.001).The nursing quality index system for assisted reproduction hospitals was established,which consisted of 3 first-level indicators,13 second-level indicators,and 39 third-level indicators. Conclusion The nursing quality index system of assisted reproduction hospitals is comprehensive,systematic and reasonable,which can be used as quality management standard and provide a reference for clinical application.

In view of the high recognition error rate and long scanning time in the existing hospital scanning technology, a new hospital operating room scanning system is designed based on personal digital assistant (PDA). The PDA scanning device adopts PIC16F877A microcontroller of 8 bit for wireless transmission through RFID and bluetooth technology, the code scanning efficiency is greatly improved. In addition, in order to improve the accuracy of image analysis, this study also adopts the energy driven sampling classification algorithm (EDS-CA) to properly preprocess the medical data information received through PDA scanning, then constructs a function classifier, and improves the image processing efficiency according to the EDS-CA reduction process. The experimental results show that the average accuracy of the code scanning system designed in this study is 95%, which proves that PDA code scanning has good performance.

COVID-19 has spread globally, infecting and killing millions of people worldwide. The use of operating rooms (ORs) and the post-anaesthesia care unit (PACU) for intensive care is part of surge response planning. We aim to describe and discuss some of the practical considerations involved in a large tertiary hospital in Singapore. Firstly, considerations for setting up a level III intensive care unit (ICU) include that of space, staff, supplies and standards. Secondly, oxygen supply of the entire hospital is a major determinant of the number of ventilators it can support, including those on non-invasive forms of oxygen therapy. Thirdly, air flows due to positive pressure systems within the OR complex need to be addressed. In addition, due to the worldwide shortage of ICU ventilators, the US Food and Drug Administration has granted temporary approval for the use of anaesthesia gas machines for patients requiring mechanical ventilation. Lastly, planning of logistics and staff deployment needs to be carefully considered during a crisis. Although OR and PACU are not designed for long-term care of critically ill patients, they may be adapted for ICU use with careful planning in the current pandemic.
