A prospective controlled randomized multicenter study to evaluate the severity of compensatory sweating after one-stage bilateral thoracic sympathectomy versus unilateral thoracic sympathectomy in the dominant side.

Objective: To evaluate the contribution that unilateral thoracic sympathectomy in dominant side or two-stage bilateral thoracic sympathectomy can have as strategies to reduce the incidence of compensatory sweating after sympathectomy for palmar hyperhidrosis.

Methods: This is a prospective, controlled, randomized multicenter trial of 200 participants with palmar hyperhidrosis, which will be randomized into two arms: (a) one-stage bilateral thoracic sympathectomy (control arm); or (b) unilateral thoracic sympathectomy in dominant side (intervention arm). At six months the participants submitted to unilateral procedure can make the contralateral surgery if they wanted it, creating a third group called two-stage bilateral sympathectomy.

Over one million cases of the SARS-CoV-2 virus have been confirmed worldwide, with the death toll exceeding 50,000 people. An important issue to be addressed concerns the exposure of health professionals to this new virus. The first reports from Wuhan province, China, described infection rates of up to 29% among healthcare professionals before the use of personal protective equipment (PPE) was fully regulated.
