Anesthesia and Analgesia
|October 29, 2009
Summary
Hemisync sounds significantly reduced intraoperative analgesic needs and postoperative pain scores in surgical patients. This innovative auditory stimulation also led to earlier patient discharge, offering a novel approach to perioperative care.
Area of Science:
- Anesthesiology
- Neuroscience
- Auditory Stimulation
Background:
- Limited data exists on Hemisync sound effects on perioperative analgesic needs.
- Investigating non-pharmacological interventions for pain management is crucial.
Purpose of the Study:
- To evaluate the impact of Hemisync sounds on analgesic requirements during and after general anesthesia.
- To assess the effect of Hemisync sounds on postoperative pain and patient discharge times.
Main Methods:
- A randomized controlled trial involving 60 surgical outpatients.
- Three groups: Hemisync sounds, music, and a control (blank tape).
- Standardized propofol-nitrous-vecuronium and fentanyl general anesthesia was administered.
Main Results:
- The Hemisync group showed significantly lower intraoperative fentanyl consumption (P < 0.05).
- Postoperative pain scores (Visual Analog Scale) were significantly reduced at 1 and 24 hours in the Hemisync group (P = 0.02, P = 0.005).
- Patients in the Hemisync group experienced earlier discharge (P = 0.048).
Conclusions:
- Hemisync sound application before and during general anesthesia decreases intraoperative analgesic demands.
- Hemisync sounds effectively lower postoperative pain perception and shorten patient recovery time.
- Auditory stimulation with Hemisync presents a promising adjunct for optimizing surgical patient outcomes.

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 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...

Parenteral Anesthetics: Overview
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.
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...
Analgesia and Pain Management
Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...
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...
