“…A small number (15%) of respondents confirmed that they had used modified PPE due to either PPE shortages or in an attempt to reduce virus transmission during aerosol-generating orthopaedic procedures. The use of modified PPE for orthopaedic surgery and other surgical specialties has already been reported ( 31 , 32 , 33 , 34 , 35 ), and future research should be directed towards new developments and the study of their comparative efficacy.…”
Orthopaedic and trauma surgeons performing surgery in the COVID-19 pandemic environment faced problems with availability, use, rationing, modification, compliance and recycling of personal protection equipment (PPE).
Orthopaedic and trauma surgeons were not well informed concerning the use of PPE for aerosol-generating orthopaedic and trauma procedures.
Scientific bodies, health authorities and management have provided insufficient guidelines for the use of PPE in aerosol-generating orthopaedic and trauma procedures.
The availability of specific PPE for orthopaedic and trauma operating theatres is low.
Hospital management and surgeons failed to address the quality of operating theatre ventilation or to conform to recommendations and guidelines.
Operating theatre PPE negatively affected surgical performance by means of impaired vision, impaired communication, discomfort and fatigue.
Existing PPE is not adequately designed for orthopaedic and trauma surgery, and therefore, novel or modified and improved devices are needed.

“…During the pandemic, several modifications of surgical helmets have been suggested in the literature. [20][21][22][23] Nevertheless, many of these investigations utilize non-standardized testing procedures, making a direct comparison with the benchmark equipment difficult, if not impossible. Furthermore, most papers lack a complete characterization of the equipment considering the safety issues and the specific threats from bio-aerosols such as the SARS-CoV-19 virus.…”
Purpose
The rapid spread of coronavirus disease 2019 (COVID-19) has increased the use of personal protective equipment. The purpose of this study was to investigate whether a commercially available sterile surgical helmet system (SSHS) can be considered protective against COVID-19 and therefore safe for use.
Methods
A double-blinded randomized controlled study was performed to investigate the efficacy of the
ViVi®
SSHS with a high-efficiency particulate air filter called
HFD Hood
(
THI
, Total Healthcare Innovation GmbH, Feistritz im Rosental, Austria) to protect against respiratory droplets. Forty recruited participants were divided into two different groups. The SSHS was tested using a validated qualitative test for respirator masks through saccharin or placebo solutions based on random allocation into two cohorts. Saccharin droplets are a validated surrogated marker for any elements of viral size, such as coronaviruses. A positive report of sweet taste after saccharin exposure was suggestive of
ViVi®
SSHS inefficacy in protection against droplets.
Results
One participant out of 21 (4.8%) reported positive for taste within the placebo cohort, while five out of 19 (26.3%) reported positive for taste within the saccharin cohort upon testing. Two out of 21 (9.5%) participants reported positive for taste within the placebo cohort, and two out of 19 (10.5%) reported positive for taste within the saccharin cohort upon retesting. There were no statistically significant differences between the saccharin and placebo groups in either the test or retest measurements (
p
= 0.085 and
p
= 1.000, respectively).
Conclusions
This study demonstrates that the
ViVi®
SSHS equipped with
HFD Hood
protects against respiratory droplets, increasing protection against several microorganisms, including the virus that causes COVID-19, allowing surgeons to carry out procedures on COVID-positive patients in a more comfortable and safer way.
