Local Anesthetics: Clinical Application as Spinal Anesthesia01:11

Local Anesthetics: Clinical Application as Spinal Anesthesia

1.9K
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 Anesthesia

946
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 Intravenous Regional Anesthesia

1.9K
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...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

1.0K
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...

Parenteral Anesthetics: Overview01:24

Parenteral Anesthetics: Overview

908
Intravenous anesthetics are drugs administered parenterally to induce anesthesia or sedation. Propofol is a widely used agent formulated as a 1% emulsion in soybean oil, glycerol, and egg phosphatide. It induces rapid anesthesia primarily due to its rapid distribution from the bloodstream to target tissues and is metabolized in the liver. However, it can cause significant pain on injection and hypertriglyceridemia. Fospropofol, a water-based prodrug of propofol, lacks these adverse effects.

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...

Summary

Preoperative administration of 6% hetastarch significantly reduces hypotension during cesarean sections compared to Ringer's lactate. This fluid management strategy improves outcomes for mothers undergoing spinal anesthesia.

Area of Science:

  • Anesthesiology
  • Obstetrics
  • Critical Care Medicine

Background:

  • Regional anesthesia is preferred for elective cesarean sections.
  • Hypotension is a common complication following spinal anesthesia.
  • Preoperative fluid administration aims to prevent hypotension.

Purpose of the Study:

  • To evaluate the efficacy of 6% hetastarch in preventing hypotension during elective cesarean sections.
  • To compare hetastarch with Ringer's lactate for preoperative fluid loading.

Main Methods:

  • 50 American Society of Anesthesiologists class I/II women undergoing elective cesarean section were studied.
  • Patients received either 1000 ml Ringer's lactate or 500 ml 6% hetastarch preoperatively.
  • Spinal anesthesia was administered, and hemodynamic variables were monitored.

Main Results:

  • Hypotension incidence was 28% in the hetastarch group versus 80% in the Ringer's lactate group.
  • Fewer ephedrine rescue treatments were needed in the hetastarch group.
  • Neonatal Apgar scores were similar and good in both groups.

Conclusions:

  • 6% hetastarch is more effective than Ringer's lactate in preventing hypotension during cesarean sections.
  • Routine use of hetastarch for preloading prior to spinal anesthesia should be considered.
  • This approach may improve maternal safety during cesarean delivery.
