General Anesthesia: Overview01:24

General Anesthesia: Overview

533
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

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...

Local Anesthetics: Clinical Application as Epidural Anesthesia

658
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

1.2K
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: Adverse Effects01:12

Local Anesthetics: Adverse Effects

729
While local anesthetics are generally safe and well-tolerated, they can occasionally cause adverse effects that vary in severity. Local anesthetics can induce toxicity at two distinct levels. They can either produce local effects through direct contact with the neural elements or be absorbed into the bloodstream from the injection site, leading to systemic effects.
Once absorbed into the systemic circulation, local anesthetics can affect the organs that depend on the functioning of sodium...

Local Anesthetics: Pharmacokinetics01:13

Local Anesthetics: Pharmacokinetics

1.1K
The potency and duration of action of local anesthetics (LAs) are determined by their pharmacokinetics. Pharmacokinetics describes how LAs are absorbed, distributed, metabolized, and eliminated from the body. When administered to the vascular tissues, LAs are quickly absorbed and enter the systemic circulation, reducing their localized effects. Adding vasoconstrictors such as epinephrine to LAs reduces their absorption into the systemic circulation, making them clinically effective. The...

Summary

Local anesthesia (LA) for stapes surgery offers shorter operating room and surgical times compared to general anesthesia (GA). Audiometric and safety outcomes are comparable, suggesting LA is a safe and efficient alternative for stapesplasty.

Area of Science:

  • Otolaryngology
  • Anesthesiology
  • Surgical Outcomes

Background:

  • Otosclerosis surgery, specifically stapesplasty, aims to restore hearing by addressing stapes bone fixation.
  • The choice of anesthesia, local anesthesia (LA) versus general anesthesia (GA), can influence surgical efficiency and patient experience.

Purpose of the Study:

  • To compare the impact of LA versus GA on audiometric results, surgery duration, quality of life, and complications in stapes surgery for otosclerosis patients.

Main Methods:

  • A comprehensive literature search was performed across five major databases (PubMed, Embase, SCOPUS, WoS, Google Scholar).
  • Studies comparing LA and GA for stapes surgery published up to May 2025 were included.
  • Meta-analyses were conducted using Comprehensive Meta-Analysis software and Review Manager.

Main Results:

  • Surgery under LA demonstrated significantly shorter operating room occupancy (MD = -17.27 min) and surgical duration (MD = -8.79 min) compared to GA.
  • No significant differences were observed in audiometric outcomes (air-conduction, bone-conduction, speech reception thresholds) or air-bone gap closure between LA and GA.
  • Complication rates were similar, with a marginally significant increase in nausea and vomiting under LA (OR = 2.578).

Conclusions:

  • Local anesthesia (LA) is associated with reduced surgical and operating room times in stapes surgery.
  • LA offers non-inferior audiometric and safety outcomes compared to general anesthesia (GA).
  • LA presents a safe and efficient alternative to GA for stapesplasty procedures.
