Summary
Inhaled lavender aromatherapy effectively reduced postoperative pain in adults. However, its impact on decreasing analgesic consumption requires further investigation through high-quality trials.
Area of Science:
- Pain Management
- Complementary and Alternative Medicine
- Anesthesiology
Background:
- Lavender essential oil is commonly used for pain relief.
- The efficacy of inhaled lavender aromatherapy for postoperative pain is not well-established.
Purpose of the Study:
- To systematically review the effects of inhaled lavender aromatherapy on postoperative pain relief.
- To assess the impact of lavender aromatherapy on analgesic consumption in adult surgical patients.
Main Methods:
- A systematic review of randomized controlled trials was conducted.
- Searches were performed across major databases up to October 2023.
- Pain scores and analgesic consumption were primary and secondary outcomes, respectively.
Main Results:
- Fifteen studies, mostly published after 2015, met the inclusion criteria.
- Lavender aromatherapy significantly reduced postoperative pain scores.
- Results on reduced analgesic consumption were mixed, with three studies showing a benefit and three showing no effect.
Conclusions:
- Inhaled lavender aromatherapy demonstrates a significant benefit in reducing adult postoperative pain.
- Current evidence is insufficient to confirm a reduction in analgesic consumption.
- Further high-quality randomized clinical trials are necessary to solidify these findings.

01:20Inhalational Anesthetics: Overview
148
Inhalation anesthetics are drugs that induce general anesthesia upon inhalation. They work by increasing the sensitivity of GABAA receptors or inhibiting NMDA receptors, leading to a decrease in central nervous system activity. The depth of anesthesia can be rapidly adjusted by changing the concentration of the inhaled gas. Some common examples of inhalational anesthetics include volatile liquids like isoflurane, desflurane, sevoflurane and gases like xenon and nitrous oxide. Isoflurane, a...

01:25Analgesia and Pain Management
403
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...

01:24General Anesthesia: Overview
170
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...

01:29Local Anesthetics: Clinical Application as Epidural Anesthesia
400
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...

01:11Local Anesthetics: Clinical Application as Spinal Anesthesia
561
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...

01:23Local Anesthetics: Common Agents and Their Applications
383
Local anesthetics (LAs) are commonly used for various applications in medical and dental procedures. Some of the common agents used are cocaine, lidocaine, and bupivacaine.
Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...
