What's the benefit of Cold laser for Vaginitis

Laser Technology and Applications in Gynaecology :

The term ‘ laser ’ is an acronym for Light Amplifi cation by
Stimulated Emission of Radiation. Lasers are commonly
described by the emitted wavelength, which determines
the color of the light, as well as the active lasing medium.
Currently, over 40 types of lasers have been developed with
a wide range of both industrial and medical uses.


Clinical effect of low intensity laser physiotherapy on vaginitis

Objective To explore the clinical effects of low intensity laser in treating

Vaginitis thods 60 patients from January to July 2018 of gynecological clinic in our

hospital were selected as study object and divided into observation group and

control group according to random numbers principle,each group was 30

cases.Patients in control group were given metronidazole suppositories,while

patients in observation group were given low intensity laser on the basis of control

group.After continue treatment for 10 days,the improvement situation of clinical

symptoms,clinical effects and recurrence rate after treatment for 6 months in two

groups were compared.Results In observation group,3 cases with leukorrhagia,4

cases with colpalgia,2 cases felt vagina burning sensation and 2 cases with vaginal

wall red congestion after treatment,which was respectively 10,12,11 and 8 cases in

control group All clinical symptoms or positive rate of sign in observation group were

obvious lower than those in control group,and the difference was statistical

significance PO.05.The treatment effective rate in observation group was

96.7%,which was higher than 76.7% in control group,the difference was statistical

significance P0.05.After treatment for 6 months,the recurrence rate in observation

group was 6.7%,which was lower than 43.3% in control group,the difference was

statistical significance PO.05.Conclusion Using low intensity laser in treating vaginitis

can obviously improve clinical symptoms,enhance clinical effects,decrease

recurrence rate and with any obvious adverse effects.It is worthy to popularize in


With the development of science and technology, more and more high-tech

means have been incorporated into clinical treatment. The laser has good

unidirectionality and good directionality.Good coherence and energy concentration.

The thermal effect of a strong laser can cause a sharp rise in the temperature of the

tissue at the irradiation site and gasification [1]. Low intensity laser photo

The local temperature rise caused by the shot does not exceed 0.75 °C, which will

not directly cause irreversible damage to the tissue. It is characterized by low output

energy and no light heat.The effect, also known as weak laser or low power laser, low

energy laser, has a wide range of applications in medicine and is often used for

non-surgical treatment. Vaginitis is a common vaginal infection in women of

childbearing age. In severe cases, it can damage the body's immune system, causing

infertility, premature birth,Fetal malformations, etc. Although there are many types

of drugs currently being treated, many of them have poor efficacy and long course of

treatment, which is difficult to cure. This study uses low intensity

Laser combined with drug treatment of some vaginitis, the effect is reported below.


  1. General Information

Sixty patients with vaginitis admitted to the gynaecological clinic of our hospital

from January to July 2018 were selected as subjects. Hospital Medical Ethics

Committee The committee approved and all participants gave informed consent.

Vaginitis diagnostic criteria 1.vaginal secretions are grayish white, sticky and uniform

2.ammonia test yang Sexual 3.vaginal pH value of 4.5, 4.was found to be positive for

secretion clue cells. Among the above four criteria, more than three can be

diagnosed, but the fourth is mandatory.Diagnostic criteria are required. The patient's

age ranged from 23 to 67 years, with an average of 35.34.8 years of disease ranging

from 1 to 14 months, with an average of 4.51.3 months. Trichomonas vaginitis 28

For example, 19 cases of senile vaginitis, 13 cases of non-specific vaginitis clinical

symptoms mainly increased vaginal discharge, vaginal burning, itching vaginal wall

redness and swelling Blood and so on. According to the principle of random number,

60 patients were divided into observation group and control group, 30 cases each.

Age distribution, etiology, course of disease, clinical symptoms

In comparison, the difference was not statistically significant (P0.05), which was

week, for a total of two courses of treatment for 10 days.

1.3 Observation indicators and criteria [9]

The improvement of clinical symptoms, clinical efficacy and recurrence rate within 6

months after treatment were compared between the two groups. The clinical

efficacy criteria were cured as follows, symptoms and signs disappeared, there was

no inflammation in the vulva and vagina, the secretion traits improved normally,

symptoms and signs were significantly relieved, vulva and vaginal inflammation

Significantly reduce the ineffectiveness, no change in symptoms and signs after

treatment, vulvar, vaginal inflammation and secretion traits have not been alleviated

or even aggravated. Effectiveness = recovery + number of cases improved by 100%.

1.4 statistical analysis

The data were analyzed by SPSS20.0 statistical software. The count data was


expressed as %. The comparison between groups was performed by 2 test. The

difference was statistically significant at P0.05.

The recurrence rate of the observation group was lower than that of the control

group at 6 months after treatment, and the difference was statistically significant


3 Discussion

Vaginitis is a common infectious disease in women of childbearing age. Under normal

circumstances, the female vagina is weakly acidic and has a natural defense function.

When this disease prevention system is destroyed, it is easy to cause vaginitis, and it

is difficult to cure and easy to relapse [10]. There are many causes of vaginitis, so the

vagina The classification of inflammation is also more complicated, the most

common are bacterial vaginitis, trichomonas vaginitis, fungal vaginitis, senile vaginitis

and aerobic bacteria Vaginitis, etc. At present, there is no conventional method for

completely effective treatment, so it is advocated to adopt comprehensive treatment

during treatment.


The current treatment methods mainly use topical medication, such as washing the

vagina with an acidic solution, using metronidazole suppository, Fuyanling capsule,

diethylstilbestrol tablet

Fill the vagina, etc. but long-term use of antibiotics can lead to dysbacteriosis, and

there are side effects. Laser thermal effect has certain electromagnetic effect

The heat and energy should be supplied to the body through heat supply, and the

rate of energy supply is lower than the heat dissipation capacity of the tissue [15].

After the heat is absorbed through the skin,It can promote and improve the blood

circulation of deep tissues and the nutrient metabolism of tissue cells, improve the

activity of tissues and cells, and improve the immune function of the body.Can in

order to play a role in promoting blood circulation, analgesia, anti-inflammatory,

swelling. In addition, the laser also has the characteristics of high energy density, and

is activated after being irradiated.The molecules of the molecule store the laser


energy for sustained slow photobiological effects.

The most popular argument for the biological effects of low-intensity lasers is the

free radical mechanism. A large number of experiments have confirmed that

low-intensity lasers can induce production.

Free radicals. Low-intensity lasers do not destroy lesions with high energy, activate

human blood proteins through specific wavelengths, and generate antiviral

substances.Promotes energy metabolism and microcirculation, reduces inflammatory

exudate, and promotes tissue repair. Simultaneously by activating the activity of

superoxide dismutase in red blood cells and It promotes the secretion of

glucocorticoids such as cyclic adenosine monophosphate and has antibacterial and

anti-inflammatory effects and regulates cellular immunity.

The results of this study showed that the improvement of clinical symptoms and

clinical treatment efficiency of the observation group were significantly higher than

that of the control group, and the recurrence rate was lower than that of the control


According to the group, the laser has great advantages in the treatment of vaginitis.

The reason may be that laser irradiation increases cytochrome oxidase and

The activity of intracellular cyclic tricarboxylase enhances the activity of the DNA

RNA protein system and promotes the proliferation and proliferation of vaginal

epithelial cells.The injection changes the internal and external environment of the

cells, and the vaginal epithelial cells increase the rate of synthesis of glycogen, and

the phagocytic ability of the white blood cells is enhanced.The pH is lowered, which

increases the resistance of the vagina.

In summary, the use of low-intensity laser therapy for vaginitis can significantly

improve clinical symptoms, improve clinical efficacy, reduce recurrence rate, and no

obvious side effects, which is worthy of clinical application.
