Resume

Research purpose: Improvement of the methods of anesthetic management with the use of

sevoflurane in the surgical treatment of cataracts in children.

Materials and methods: 54 sick children were studied during ophthalmosurgical interventions

under combined anesthesia based on the use of sevoflurane.

Results and discussion: The data obtained from studies of central hemodynamic parameters

showed minimal changes in the response of systemic hemodynamics, which were associated with
the peculiarities of the pharmacological action of both fentanyl and sevoflurane. It should be noted
that this condition during anesthesia characterized the state of moderate circulatory hypodynamia.

Keywords: anesthesia in children, inhalation anesthetics, sevoflurane, fentanyl, central

hemodynamic parameters.

Relevance

Clouding of the lens - cataract in children is

one of the leading causes of primary blindness
[1]. One of the priority anesthesia drugs in the
surgical treatment of cataracts in children, the
most widely used in pediatric practice, is the
inhalation anesthetic sevoflurane [2,3,5]. The
drug,

characterized

by

dose-dependent

respiratory depression, with a minimal effect on
the cardiovascular system, allows for highly
controlled inhalation anesthesia with instant
induction and rapid awakening, contributing to
the rapid postoperative recovery of the patient's
consciousness [4,8]. Sevoflurane has no negative
hemodynamic effects, slightly affects intracranial
and intraocular pressure [6,9,13]. It is possible to
perform anesthesia using low- and minimal-flow
techniques, which provide more favorable
environmental conditions in the respiratory
circuit, which gives a positive economic effect.
The use of modern drugs for general anesthesia
and these schemes for conducting anesthesia,
both during induction and during intraoperative
and postoperative management of the patient,
made it possible to avoid many negative reactions
inherent in other anesthetics, such as ketamine,
halothane, sodium thiopental, which can cause
hypertensive syndrome , increase intraocular
pressure, motor reactions, increase the time of
recovery from anesthesia [9,10,11,12].

Thus, general anesthesia with sevoflurane in

the surgical treatment of cataracts in children is
decisive and optimal.

Purpose:

Improving

the

methods

of

anesthetic management using sevoflurane in the
surgical treatment of cataracts in children.

Material and methods

To provide anesthetic protection in 54 sick

children during ophthalmosurgical interventions,
the following combinations were used: fentanyl
with sevoflurane (Group 1 - 55.6%), fentanyl
with propofol (Group 2 - 44.4%).

Children aged 2

4 years accounted for 62.9%,

children aged 5

7 years accounted for 37.1% of

the total number of patients.

Anesthesia was performed during operations

of congenital and traumatic cataracts with the
imposition of an IOL (implantation of an
artificial lens). The duration of anesthesia in
59.4% of patients was up to 1 hour, in 40.6% - up
to 2 hours.

Patients of the 1st group after premedication

began inhalation of sevoflurane up to 3 vol%.
Fentanyl was administered intravenously at a

dose of 3 µg/kg. All patients underwent tracheal

intubation against the background of the
introduction of arduan at a dose of 0.06 mg/kg.
IVL was performed using the Drager Fabius plus
device (Germany) along a semi-closed circuit.
Myorelaxation

was

maintained

by

the

introduction of 1/3 of the main dose of arduan.
Anesthesia was maintained by inhalation of
sevoflurane at a dose of 1.0

2.0 vol%. Infusion

therapy was carried out at a rate of 5 - 7
ml/kg/hour. After the end of the operation with
the advent of adequate spontaneous breathing, the
trachea was extubated. After the operation, the

patients woke up quite quickly, within 13.8±0.8

minutes.

Patients of the 2nd group received bolus

propofol (3 mg/kg) and fentanyl 0.005% (0.03
mg/kg) during the induction period [7,14]. For
operations lasting more than one hour, the
maintenance of the surgical level of anesthesia
was carried out by repeated administration of
fentanyl at a dose of 1/2 or 1/3 of the initial dose.
The dose of propofol during the period of
maintenance

of

anesthesia,

which

was

administered through the lineomat, averaged

7.3±0.4 mg/kg/h. The duration of the awakening
stage was 15.5±5.6 min.

The study of hemodynamics was carried out

on the echocardiograph "SonoScape" (China)
with a sensor of 3.5 MHz. Echocardiography

(EchoCG)

parameters

were

calculated

automatically. The following values were
determined: stroke index (SI) = SVR/S ml/m2,
cardiac index (CI) = MOS/S l (min*m2), specific
peripheral resistance (SIR) = SBP/SI in conv.
units Computer analysis of echocardiography
made it possible to calculate indicators of
myocardial contractility and diastolic function of
the left ventricle.

Measurement of intraocular pressure was

made according to A.N. Maklakov. Normal IOP
is 16 - 23 mm. rt. Art. Patients had IOP measured
before and after surgery.

The results of clinical and functional studies

were processed by the method of variation
statistics Student's T-test....

Result and discussion

The results of the study of hemodynamic

parameters during combined anesthesia with the
use of fentanyl and sevoflurane are presented in
Table 1.

Compared with the initial data on the

premedication background, there was an increase
in heart rate by 17.52% and a decrease in specific
peripheral resistance (RPS) by 20.74%. It should
be noted that patients of the first group reacted

more significantly to induction anesthesia and
anesthesia. Even before the start of anesthesia,
they had tachycardia on the operating table. This
was due to the psycho-emotional stress of
patients.

Other indicators changed slightly. After the

administration

of

fentanyl,

hemodynamic

parameters such as stroke index (SI), mean
dynamic pressure (DDP), cardiac index (CI),
ejection fraction (FI) and heart rate decreased
compared with those of the premedication period,
respectively, by 14.21% ( P<0.05), 3.98%,
8.57%, 4.19% and 2.79%, excluding HIPS. These
significant differences in the response of
systemic hemodynamics are associated with the
peculiarities of the pharmacological action of
both fentanyl and sevoflurane.

It should be noted that this condition

characterized the state of moderate circulatory
hypodynamia. Sevoflurane mainly affects the
tone of the peripheral vascular bed, causing
vasoplegia, fentanyl reduces cardiac output,
increasing vascular vasoplegia. 10 minutes after
intubation, there was a significant increase in SI
by 20.44%, SI by 21.65%, and DDS by 8.53%,
while at the same time, there was a decrease in
UPS by 13.76% (P<0.05).

There was a trend towards a decrease in the

index of the fraction of exile (FI). In the period of
maintenance of anesthesia, certain changes in the
indicators of central hemodynamics were also
observed. Thus, at the stage of skin incision,

compared with the previous period, there was a
decrease in DDS by 6.52%, heart rate - by 8.49%,
CI - by 12.84%. At the same time, there was an
increase in the SPS by 13.44%.

were

the

limited

Under

Against the background of induction into

anesthesia, a slight decrease in indicators was
observed: CI, HR, SI and SBP by 1.44%, 2.42%,
1.48% and 6.37%, respectively. At the same
time, the SSA and FI increased slightly - by 0.1%
and 0.13%, respectively, which turned out to be
statistically unreliable (P>0.05). Compared with
the stage of premedication, there was a decrease
in heart rate by 12.01%, SBP by 7.17% (P<0.05).
Given the hypotensive effect of fentanyl and
propofol, the infusion was started without waiting
for the fall in blood pressure. This approach made
it possible to prevent, and in some cases

completely eliminate the critical drop in blood
pressure at all stages of anesthesia.

At the end of the operation, hemodynamic

parameters remained stable. The changes we
found in the studied parameters at the stages of
the operation were unreliable, except for the SI
and SBP indicators. In relation to their initial
value, there was some change, which was
expressed by an increase in CI by 26.22%, a
decrease in SBP by 9.23% (P<0.05).

During anesthesia in the 1st group of patients

in the postoperative period, there was an
unreliable decrease in IOP by 13.43%, in the 2nd
group - 7.44% (Table 3).

system to combined anesthesia and surgery in
children

with

pathology

is

accompanied by a slight and compensated change
in the main hemodynamic parameters.
2. Anesthesia using fentanyl with sevoflurane and
fentanyl with propofol is accompanied by a
decrease in IOP, which creates optimal
conditions for the surgical treatment of cataracts
in children.
