[Controlled myorelaxation in patients with aldosteroma]
Anesteziologiia I Reanimatologiia
|December 18, 2013
Summary
Controlled myorelaxation during aldosteroma surgery is achievable with neuromuscular monitoring. Continuous infusion of rocuronium bromide (esmeron) reduces consumption and ensures high-quality relaxation, while sugammadex offers rapid reversal.
Area of Science:
- Anesthesiology
- Surgical Oncology
Background:
- Aldosteroma surgery requires precise muscle relaxation.
- Monitoring neuromuscular conduction (NMC) is crucial for patient safety.
Purpose of the Study:
- To develop controlled myorelaxation techniques for aldosteroma patients undergoing surgery.
- To evaluate different neuromuscular blocking agents and reversal strategies.
Main Methods:
- Video-assisted retroperitoneal adrenalectomy under general anesthesia with sevoflurane.
- Four groups of patients received varying rocuronium bromide (esmeron) administration (continuous infusion vs. bolus).
- Neuromuscular blockade reversal was assessed using proserin or sugammadex.
Main Results:
- Continuous esmeron infusion (Group 1) resulted in minimal consumption and prolonged neuromuscular blockade recovery (>19 min).
- Bolus esmeron without reversal (Group 2) showed the slowest recovery.
- Proserin (Group 3) reduced recovery time 2.5-3 times compared to Groups 1 & 2.
- Sugammadex (Group 4) achieved a 4.7-fold faster recovery than proserin, with no risk of re-blockade.
Conclusions:
- Controlled myorelaxation is feasible in aldosteroma surgery with NMC monitoring.
- Continuous esmeron infusion optimizes drug use and relaxation quality.
- Sugammadex provides superior and safer neuromuscular blockade reversal compared to proserin.

01:26Heart Failure Drugs: Inhibitors of Renin-Angiotensin System
1.9K
The activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS) contributes to cardiac remodeling, and inhibiting the RAAS is a pharmacological target in heart failure management. As a result, neurohumoral modulation is a crucial treatment principle for managing heart failure. This approach involves using medications like ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), β-blockers, mineralocorticoid receptor antagonists (MRAs), and neutral...

00:59Direct-Acting Cholinergic Agonists: Pharmacological Actions
2.3K
Direct-acting cholinergic agonists exert their pharmacological actions by mimicking the effects of acetylcholine on postsynaptic muscarinic receptors to generate parasympathetic responses. These agents elicit a range of physiological responses, including cardiovascular effects. For example, activation of muscarinic receptors induces bradycardia, decreased cardiac output, reduced peripheral resistance, and consequent hypotension. In the eye, stimulation of M3 receptors leads to smooth muscle...

01:31Skeletal Muscle Relaxants: Therapeutic Uses
1.2K
Skeletal muscle relaxants are used to relax muscle tone and alleviate painful muscle contractions. However, the choice of skeletal muscle relaxants depends on the duration of the surgical procedure in order to minimize potential side effects. Skeletal muscle relaxants like neuromuscular blocking agents [NMBAs] are commonly employed as adjuvants alongside general anesthetics in clinical settings. NMBAs are also used to maintain controlled ventilation during surgery of the larynx or pharynx...

2.0K
Adrenergic agonists have diverse therapeutic uses across various medical conditions and emergencies.
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.

1.2K
Skeletal muscle relaxants are widely used for muscle paralysis and relieving pain following any muscle injury or stiffness. However, depending on the drug type, they can have adverse effects that range from mild to severe. Usually, nondepolarizing neuromuscular blockers have minimal side effects. For example, drugs like d-tubocurarine, cisatracurium, and rocuronium cause hypotension, whereas drugs like baclofen, when stopped abruptly, can lead to the recurrence of spastic conditions.
