Local Anesthetics: Clinical Application as Spinal Anesthesia

Local Anesthetics: Clinical Application as Spinal Anesthesia

Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...

General Anesthesia: Overview

General Anesthesia: Overview

Anesthesia is a medical procedure that uses drugs for CNS suppression to enable painless surgeries and procedures. The selection of anesthetics is influenced by their pharmacokinetic properties, side effects, and patient characteristics. Various types of anesthesia include general, local, regional, spinal, and inhalational.
General anesthesia induces unconsciousness in the whole body, while the others target specific areas or sensations. It is administered to minimize adverse effects, maintain...

Stages of General Anesthesia

Stages of General Anesthesia

Various sedation levels offer significant advantages in facilitating procedural interventions for patients undergoing medical or invasive surgical procedures. These levels span from anxiolysis to general anesthesia, providing a spectrum of sedative effects to cater to specific patient needs. Anxiolysis reduces anxiety and is achieved through minimal sedation, enabling patients to remain awake and responsive while feeling more at ease during the procedure. This level can benefit minor...

Aneurysm IV: Nursing Management

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...

Anaesthesia for carotid artery surgery

|March 1, 1980

Summary

This study explored a new anesthesia technique for carotid endarterectomy using droperidol, fentanyl, and a cervical plexus block. This method safely allowed motor function testing during carotid clamping, often avoiding the need for a shunt.

Area of Science:

Neurosurgery
Anesthesiology

Background:

Carotid endarterectomy is a surgical procedure to remove plaque from carotid arteries.
Maintaining cerebral perfusion during carotid clamping is crucial.

Purpose of the Study:

To evaluate the safety and efficacy of a combined anesthetic technique for carotid endarterectomy.
To assess the feasibility of intraoperative neurological monitoring without a shunt.

Main Methods:

Twenty-one carotid endarterectomies were performed on 18 patients.
Anesthesia was induced using droperidol, fentanyl, and a cervical plexus block.
Motor function was tested during carotid clamping.

Main Results:

The anesthetic technique facilitated safe testing of motor function during carotid clamping.

A shunt was not required in the majority of the cases.

The procedure was performed safely in all patients.

Conclusions:

Combined droperidol, fentanyl, and cervical plexus block anesthesia is a viable technique for carotid endarterectomy.
This approach allows for safe intraoperative neurological assessment and often obviates the need for shunting.
