摘要

The authors report a well-tolerated procedure in all patients. One may be skeptical about this for many reasons. First, the objective criteria for failure or inadequacy of LA and aborting the procedure (if required) were not defined. These could have been either level or duration of intra-operative pain or frequency oT top-up instillations of LA and sedation.. Intraoperative tolerance was judged subjectively. Patients were prepared for intraoperative potential pain by preoperative explanation. Apart from the increasing pain threshold, this may also increase chances of a biased subjective reporting of pain scores (reporting them lower) and tolerability (reporting it good). Second, the study reports a definite intraoperative pain with a mean score of 3.62.
