Thermal imaging and planimetry evaluation of the results of chronic wounds treatment with hyperbaric oxygen therapy
Background. One of the methods to treat chronic wounds is the use of hyperbaric oxygen (HBO). Objective
measurement of the wound surface is an important element in the process of monitoring and predicting
the progress of treatment.
Objectives. The aim of the study was to evaluate the effect of hyperbaric oxygen therapy (HBOT) on ulcer
wound healing in patients with chronic venous insufficiency ulcers and diabetic foot syndrome using thermal
imaging and computerized planimetry.
Material and methods. During a 3-year period, 284 digital computer planimetry measurements were
gathered from 142 patients treated for leg ulcers caused by chronic venous insufficiency and ulcers from
diabetic foot syndrome at HBOT Unit of the Dr Stanis艂aw Sakiel Centre for Burns Treatment in Siemianowice
艢l膮skie (Poland). Each patient took 30 HBOT sessions using a Haux multiplace HBO chamber at a pressure of 2.5
atmospheres absolute (ATA). The results of the treatment were monitored using thermovision and computerassisted
planimetry measurements performed before and after HBOT.
Results. Both groups of patients exhibited a reduction in the surface and perimeter of the wound after
HBOT. The treatment effects were also confirmed with thermal imaging. The areas calculated from thermal
imaging and planimetry are different but correlated.
Conclusions. It seems that a combination of thermal imaging and planimetry may enhance the diagnosis
as well as provide the physician with more information about therapy effects
Thermal effects of topical hyperbaric oxygen therapy in hard-to-heal wounds - a pilot study
Clinical studies have been performed to evaluate the thermal response of topical hyperbaric
oxygen therapy (THBOT) in patients suffering from hard-to-heal wounds diagnosed as venous leg
ulcers located on their lower extremities. It was found that this therapy leads to a temperature
decrease in areas around the wound. Moreover, a minor temperature differentiation between all
areas was seen in the third period of topical hyperbaric oxygen therapy (THBOT) that may suggest
that microcirculation and thermoregulation improvement start the healing process. On the other
hand, the results of the conducted studies seem to prove that thermal imaging may provide a safe
and effective method of analyzing wound healing of hard-to-heal wounds being treated with THBOT.
This is the first study that tries to show the possibilities of a very new method by evaluating treatment
of hard-to-heal wounds using thermal imaging, similar to the hyperbaric oxygen therapy effects
evaluated by thermal imaging and described previously. However, the first clinical results showed a
decrease in temperature due to the THBOT session and some qualitative similarities in the decrease
in temperature differentiation between the studied areas and the temperature effects obtained due to
hyperbaric oxygen therapy
Thermal imaging in burns diagnostics
W ostatnich latach nast膮pi艂 ogromny rozw贸j w zastosowaniu
termowizji w medycynie. Wizualizacja rozk艂adu temperatury
ludzkiego cia艂a stanowi bardzo cenne informacje diagnostyczne,
odzwierciedlaj膮c istotne procesy metaboliczne zachodz膮ce
w organizmie. W zwi膮zku z powy偶szym, wszystkie odst臋pstwa od
typowej warto艣ci temperatury badanego fragmentu cia艂a mog膮
艣wiadczy膰 o nieprawid艂owo艣ci w fizjologii organizmu.
Niniejsza praca prezentuje pierwsze do艣wiadczenia naszej grupy
badawczej w pokazaniu znaczenia nieinwazyjnej techniki obrazowania
cia艂a cz艂owieka, kt贸ra mo偶e by膰 przydatna w diagnostyce
oparze艅.
Maj膮c na celu szybkie, bezbolesne oraz 艂atwo dost臋pne diagnozowanie
ran oparzeniowych, termowizja mo偶e stanowi膰 pomocnicze
urz膮dzenie do automatycznego wyznaczania obszar贸w
wymagaj膮cych leczenia chirurgicznego oraz wyodr臋bnienia obszar贸w
nadaj膮cych si臋 do leczenia zachowawczego.
Grup臋 badawcz膮 stanowi艂o 25 pacjent贸w zakwalifikowanych
w zakresie stopnia IIa, IIb oraz III. Badania zosta艂y przeprowadzone
we wsp贸艂pracy z Centrum Leczenia Oparze艅 im. dr. Stanis艂awa

Wst臋pna analiza termograficzna obszar贸w zainteresowania
wskazuje na r贸偶nice w warto艣ciach 艣rednich temperatur pomi臋dzy
obszarami obj臋tymi oparzeniem a obszarami s膮siaduj膮cymi.There was dynamic increase in use of thermal imaging in
medicine during last two decades. Visualization of body
surface thermal map brings some important diagnostic information
about metabolically activity of the inner tissue and the
differences in observed body temperature in comparison with
normal body temperature range may suggest disease process
occurring. Presented studies are the first step of our research
group in the thermal imaging of skin burns.
It seems that non-invasive, fast and simply in use thermovision
may bring some important and useful information in evaluation
of skin burns.
The study included 25 patients suffered from skin burns in IIa,
IIb and III stage. The study was carried out at Burn Treatment
Center memorial Dr Stanislaw Sakiel in Siemianowice 艢l膮skie.
Preliminary analysis showed some differences in mean temperature
characterized areas in II and III burn stage
