Recognition of positive and negative effects of machines through the investigation of perceptions of nurses is the first step before looking for ways of maximizing advantages and facing disadvantages of equipment use.

Inadvertent hypothermia is one of the most common complications experienced by surgical patients who are transferred to the postanesthesia care unit (PACU). Appropriate pacu length of stay (LOS) is defined as the time required for a patient to achieve a physiologically stable condition after anesthesia administration. In studies measuring appropriate LOS, patients who arrived hypothermic in the PACU had longer stays than those who arrived normothermic. The aims of this study were to determine whether the actual and appropriate LOS in the PACU differs between hypothermic and normothermic patients and to identify differences between subgroups of patients according to age, gender, and type of anesthesia administered.

The admission of intensive care unit (ICU) overflow patients in the post anaesthesia care unit (PACU) has come about as a result of an increasing demand for ICU services, which is not followed by a respective increase in the number of available beds. This has raised many concerns from nurses, with extensive workload and lack of personnel being the most important. This study was conducted in the General University Hospital of Patras, Greece, from 1 January 2003 to 30 June 2004. Admissions of ICU patients in the PACU were recorded and Project Research in Nursing (PRN), a Canadian workload measurement system, was used to estimate nursing workload. One hundred and three ICU patients were admitted and they stayed for a total time of 2812 hours. PRN scores of these ICU patients were much higher than for post anaesthesia patients. Clinically important increases of total PRN score, total care time and nursing personnel needs were evident in the presence of an ICU overflow patient during all shifts. Unless there is the appropriate number of personnel, increases in total care time are likely to lead to the neglect of post anaesthesia patients' needs.
