In their study, the EMG was performed after the manual examination, the needle was 'redirected twice if the first insertion failed to find the spontaneous electrical activity' and the needle electrode length varied with different muscles.
There were three failed NGT placements on the first attempt in Group S. One insertion failed because the highwayman's hitch unexpectedly untied during the procedure.
However, orbital insertion failed, so the probe orbited the Sun until it made another, successful attempt at circling Venus in December 2015.
If the occluded main portal vein or superior mesenteric vein cannot be recanalised or the TIPS insertion fails, the patients will be treated with conventional therapy.
DEB insertion failed in 19 % of the cases and angioplasty was finally performed using a conventional PTCA balloon.
Gastric tube insertion failed in three participants in the Blind group, and reinsertion was attempted using the King Vision video laryngoscope.
When initial insertion failed, catheterisation was again attempted at the same vein.
A single RCT reporting a follow-up of 12 months following implant insertion failed to show a significant impact of the PS technique on peri-implant MBL changes (Enkling et al. 2011).
If LMA-S insertion failed, patients had to be ventilated by BVM.
The insertion was scored as (1, insertion of device at first attempt without resistance; 2, insertion of device at first attempt with resistance; 3, insertion of device successful at second attempt; 4, insertion failed at second attempt) [ 7].
When the risk for mechanical complications is unacceptable or when subclavian catheter insertion fails, insertion should be attempted through the internal jugular vein or femoral vein, and the catheter should be tunnelled to reduce the risk for infection.
