Local Anesthetics: Clinical Application as Spinal Anesthesia01:11

Local Anesthetics: Clinical Application as Spinal Anesthesia

585
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 Epidural Anesthesia01:29

Local Anesthetics: Clinical Application as Epidural Anesthesia

414
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...

Pre-Procedural Guidelines for Assessing Blood Pressure01:10

Pre-Procedural Guidelines for Assessing Blood Pressure

522
Accurate blood pressure assessment is crucial for diagnosing and managing various health conditions. To ensure the reliability of these measurements, healthcare professionals must adhere to standardized pre-procedural guidelines. These guidelines enhance patient safety and improve the overall quality of healthcare. The following steps are essential for obtaining accurate and consistent blood pressure readings, from using the appropriate tools to ensuring effective communication with the...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

53
Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

General Anesthesia: Overview01:24

General Anesthesia: Overview

196
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 Anesthesia01:16

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia

367
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...

Summary

Implementing an evidence-based protocol for cesarean sections did not significantly reduce overall spinal-induced hypotension. However, the protocol eliminated hypotension when utilized, reducing vasopressor use.

Area of Science:

  • Anesthesiology
  • Obstetrics
  • Quality Improvement

Background:

  • Spinal anesthesia commonly causes hypotension during cesarean sections.
  • Existing protocols aim to mitigate this risk.
  • Effective implementation is key to patient outcomes.

Purpose of the Study:

  • To implement and evaluate an evidence-based intraoperative protocol.
  • To reduce the incidence of spinal-induced hypotension.
  • To assess protocol impact during elective cesarean sections.

Main Methods:

  • A quality improvement project was conducted.
  • Anesthesia providers received education on the protocol.
  • Intraoperative anesthesia records were reviewed pre- and post-implementation.

Main Results:

  • Overall hypotension incidence did not significantly decrease (P=.554).
  • Hypotension was eliminated in patients treated per protocol (0% vs. 22%).
  • Rescue phenylephrine use decreased by 39.4% (P<.001) and ephedrine by 27.8% (P=.001).

Conclusions:

  • The protocol effectively eliminated hypotension when used.
  • Low provider utilization (18%) limited overall impact.
  • Further interventions are needed to increase protocol adoption and staff training.
