Local Anesthetics: Clinical Application as Epidural Anesthesia

Local Anesthetics: Clinical Application as Epidural Anesthesia

Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

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...

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia

Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.
One of the advantages of...

Aneurysm IV: Nursing Management

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...

Area of Science:

Anesthesiology
Regional Anesthesia
Surgical Anesthesia

Background:

Cervical epidural anesthesia is a regional technique used for various surgeries.
Thyroid surgery anesthesia can be challenging due to patient-specific factors.

Purpose of the Study:

To evaluate the effectiveness and safety of cervical epidural anesthesia for thyroid surgery.

Main Methods:

A prospective study compared cervical epidural anesthesia (n=9) with general anesthesia (n=44) for thyroid surgery.
Epidural catheters were placed at C(7)-T(1) with Lignocaine and adrenaline.

Main Results:

Successful cervical epidural anesthesia in 8 of 9 patients, providing conscious sedation and effective analgesia.
No significant complications, particularly regarding diaphragmatic function and cardiovascular stability.
General anesthesia patients experienced complications like intubation issues, arrhythmias, and hypotension.

Conclusions:

Cervical epidural anesthesia is a viable option for thyroid surgery.
Consider this technique for patients with anticipated difficult intubation or cardiovascular vulnerabilities.
It offers a safer alternative to general anesthesia in specific high-risk thyroid surgery cases.
