All operations were performed successfully and the mean operating time was 2 hours and a half.
Mean operating time was 245.9 min (SD 88.1 min).
For repairable products, average life is the mean operating time between failures [15].
Mean time to install was 7.3 min, and mean operating time was 6.6 min.
Mean time needed to install equipment was 8.7 min, and mean operating time was 18.2 min.
Childers et al. found a mean operating time of 149 min in patients who did not undergo a hysterectomy during their laparoscopic staging, and a mean operating time of 196 min in patients who did undergo a hysterectomy [9].
The main intraoperative blood loss was 154 ml (range 85 310) and mean operating time was 145 min (100 245).
Mean operating time was not different between the two groups (group S, 92 ± 73 minutes; group C, 100 ± 74 minutes).
Data obtained from case notes indicated a mean operating time (surgery only) was 50 minutes (20 80), and mean radiation exposure was 18 seconds (5 42).
The trial reports a mean operating time of 71 min, a postoperative morbidity of 86%, and a mean hospital stay of 7 days for the open approach.
The mean operating time between failures, namely, the failure rate, increased in the following order: auxiliary systems, traction system, running gear, brake system, and control and diagnostic systems.
