Local Anesthetics: Clinical Application as Epidural Anesthesia01:29

Local Anesthetics: Clinical Application as Epidural Anesthesia

865
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

1.6K
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...

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia

1.6K
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.

General Anesthesia: Overview

868
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...

Area of Science:

  • Anesthesiology
  • Surgical Procedures

Background:

  • Combined spinal-epidural anesthesia (CSE) is an advanced technique for surgical pain management.
  • Optimizing CSE for abdominal surgeries requires careful dose and technique selection.

Purpose of the Study:

  • To evaluate the efficacy and safety of a specific CSE technique in patients undergoing abdominal surgery.
  • To assess the onset, duration, and quality of the anesthetic block.
  • To identify any complications associated with the CSE procedure.

Main Methods:

  • Fifty patients undergoing abdominal surgery received CSE using a "needle-through-needle" technique.
  • Intrathecal injection: 1.0 mL of 5% lignocaine.
  • Epidural injection: 10 mL of 0.5% bupivacaine.
  • Epidural catheter placement for supplemental analgesia.

Main Results:

  • Immediate onset of intense and prolonged anesthetic block achieved.
  • Controllable duration of anesthesia and effective postoperative analgesia.
  • No instances of post-spinal headache were reported.
  • Five patients experienced transient intraoperative hypotension requiring correction.
  • No other spinal or epidural anesthesia complications occurred.

Conclusions:

  • The evaluated CSE technique is effective for abdominal surgery, offering rapid onset and controllable, long-lasting anesthesia.
  • This CSE approach provides significant advantages, including the absence of post-spinal headaches.
  • Careful monitoring for and management of potential hypotension are necessary.
