Stellate Ganglion Block in Control of Arrhythmia in Laparoscopic Cholecystectomy
A study testing right stellate ganglion block in people with Arrythmia and Pain, Acute, run by Assiut University at 1 site in Egypt.
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). Read more about this study

About this study
Official title: Stellate Ganglion Block Efficacy in Control of Arrhythmia and Cardiovascular Changes in Addition to, Postoperative Analgesia in Laparoscopic Cholecystectomy
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.
Read the detailed 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
right stellate ganglion blockProcedure or surgery
The skin should be anaesthetised with lidocaine 2%. Using a lateral approach and in-plane imaging, a blunt regional anaesthesia needle should be advanced deep to the carotid sheath towards the longus colli muscle. Following careful aspiration, inject 10 ml lidocaine 2% that will result in expansion of the fascia of the longus colli. Confirmation of the SGB success can be detected by warming of left upper limb and left Horner's syndrome.
| Study group | Role | What they receive |
|---|---|---|
| Stellate Ganglion block group | Active comparator | will include 20 patients: each one will receive 10 ml lidocaine 2% right stellate ganglion block (RSGB) under sonar guidance Receives: Procedure: right stellate ganglion block |
| Control group | No intervention | will include 20 patients: a control group |

The primary outcome is the main question the study is designed to answer.

What does the primary outcome measure?
Arrhythmia (time frame: introperative period). It is what the study was designed to measure, not a finding.

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Dec 2023.
