Clinical Trial Summary
During Laparoscopic cholecystectomy, carbon dioxide (CO2) pneumoperitoneal laparoscopic
surgery, CO2-pneumoperitoneum activates the sympathoadrenomedullary system to increase the
release of catecholamines such as epinephrine (E) norepinephrine (NE) and dopamine (DA).
During stress, E and NE are secreted by the adrenal medulla into blood circulation to promote
glycogenolysis to increase blood glucose, speed up lipolysis and accelerate heartbeats.
Stellate g anglion block (SGB) reters to the blockade of sympathetic nerves including the
large area covered by middle cervical, vertebral arterial. stellate ganglions and ther pre-
and post- ganglions. SGB affects both peripheral and central nervous systems. In the
peripheral system. the sympathetic pre- and post-ganglionic fibers in the innervated areas of
stellate ganglion are affected. Therefore, the control of vascular dilatation and
constriction, muscular movement, bronchial smooth muscle relaxation and contraction, and pain
conduction, by sympathetic nerves is inhibited. In the central nervous system, the
hypothalamus is mainly involved in the regulation of systemic autonomic nervous, immune and
endocrine systems, and to maintain homeostasis.
CO2-pneumoperitoneum causes severe stress-related homeostatic disorders including arrhythmia
and blood pressure changes. This study will examine the effects of stellate ganglion block
(SGB) on hemodynamics and stress response in patients undergoing CO-pneumoperitoneal surgery.
Description:
Laparoscopic surgery is being increasingly recognized for its advantages of minimal
invasiveness. mild postoperative pain, short length of hospitalization and rapid recovery and
is widely used in general surgery, obstetrics. gynecology and urology. Laparoscopic
cholecystectomy (LC) has become the gold standard for surgically treating benign diseases of
the gallbladder.
During carbon dioxide (CO2) pneumoperitoneal laparoscopic surgery, CO2-pneumoperitoneum
activates the sympathoadrenomedullary system to increase the release of catecholamines such
as epinephrine (E) norepinephrine (NE) and dopamine (DA). During stress, E and NE are
secreted by the adrenal medulla into blood circulation to promote glycogenolysis to increase
blood glucose, speed up lipolysis and accelerate heartbeats. Stellate g anglion block (SGB)
reters to the blockade of sympathetic nerves including the large area covered by middle
cervical, vertebral arterial. stellate ganglions and ther pre- and post- ganglions. SGB
affects both peripheral and central nervous systems. In the peripheral system. the
sympathetic pre- and post-ganglionic fibers in the innervated areas of stellate ganglion are
affected. Therefore, the control of vascular dilatation and constriction, muscular movement,
