However, it may well be related to the smaller magnitude of the operation and the corresponding decreased operation time and blood loss.
Actually, due to no generic product of alfentanil available at present time, alfentanil 0.5 mg is about 11 times expensive than fentanyl 0.05 mg, which is not offset by other costs such as decreased operation time, shorter recovery time or hospital stay, and earlier resumption of normal activities.
First, cycle time continuously decreases because of the decrease of operation time of the bottleneck station as a consequence of learning.
When the 10-years aged refuse was disinfected by 20% NaClO (wt%), COD, biochemical oxygen demand (BOD5), total nitrogen (TN), and ammonium N removal showed a dramatic decrease throughout operation time from 84.4 86.2% to 15.2 34.5%, 94.4 99.8% to 26.2 54.4%, 31.2 33.9% to 2.1 10.1%, and 88.5 90.1% to 1.5 14.5%, respectively, suggesting biodegradation is the dominant contaminant removal.
We demonstrated that the combination of laparoscopic nephrectomy and open thrombectomy could decrease the operation time and blood loss.
It is clear from Fig. 12 that CE of BPMED stack decreased with operation time for both types of IEM systems.
the implementation of the RRS did not reduce the CPA incidence during non-operation time (0.80 vs. 0.73, p = 0.573), but decreased during operation time (0.86 vs. 0.52, p = 0.001).
The electrochemical performance of the electrodes, anodes and cathodes, decreases during the operation time in both operation modes, operated with pure gases as well as with CO2 containing gases.
It can be estimated that video-endoscopic procedures should take more time due to the setup of the video-screen during surgery, but the operation time should decrease with growing surgeon's skills.
