The committee was advised that the possible advantages of using the Mega Soft Patient Return Electrode would be significantly influenced by whether it was used for inpatient or for day-case surgery. It heard that at least half of operations performed in the NHS are carried out as day cases and for these a fixed operating table is not generally used. For inpatient operations, the Mega Soft Patient Return Electrode can be placed on the operating table at the start of a day and left in place throughout any operating list. Patients can then be placed on the Mega Soft Patient Return Electrode when they are moved from the trolley on which they are anaesthetised to the operating table. The Mega Soft Patient Return Electrode is left on the operating table and cleaned between patients. By contrast, most day-case surgery is performed with the patient on a trolley. Patients are anaesthetised while on the trolley, which is then moved into the operating theatre and then to the recovery area: the patient remains on the same trolley throughout. This means that at least 2 Mega Soft Patient Return Electrodes would be needed for each day-case operating suite. Otherwise, placing each patient on the Mega Soft Patient Return Electrode would involve more time and inconvenience than applying and removing a standard disposable single-use patient return electrode. The committee concluded that the patient, health system and any cost advantages of the Mega Soft Patient Return Electrode were likely to be realised only when it was used for inpatient surgery and not for day-case surgery.
