Operating theatres study

One of the most potent routes for transmission of bacterial disease is via the air. Cross-infeetion in hospital wards, infeetion in operating theatres, the transmission of disease in elosed spaces such as cinemas and other places of assembly, in the ward rooms and erew s quarters of ships and in submarines are all well known. Of equal importance is the provision of a bacteria-fiee environment for aseptic manipulations generally. Clearly, the disinfeetion of atmospheres is a worthwhile field of study and to this end much research has been done. It is equally clearly important to be able to evaluate preparations claimed to be air disinfeetants. 

Teams, like individuals, may erode or create safety. For instance, in their study of communication in the operating theatre, Lorelei Lingard and colleagues (2004) classified about a quarter of operation relevant communications they observed as communication failures. Events were classified as failures because they were made too late or too early, because essential content was missing.

Launched as a rratiortal safety improvemerrt irritiative by the National Patient Safety Agency in 2009, the wide variation in approaches to its implementation provide a good case study about how safety crrltures vary across different hospitals. Implementation approaches for the WHO Srrrgical Safety Checklist have ranged from the please use this checklist in yorrr operating theatre from next Monday to, at the other end of the spectrurrr, well designed implemerrtation plans (Box 7.3).

The work presented in Section 12.7.1 was limited to one type of suture, size and power, and the suture used was uncoated braided polyester that tended to develop a secure knot in the 1=1 configuration. Tlie previously unknown effects of a change in power, and suture material and size on knot tensile properties were determined in this study. The laser used was one that was conunerdaUy available and generally found in operating theatres.
