Summary
For cancer pain unresponsive to standard treatment, intraspinal drug delivery offers an alternative. Trials ensure safety and efficacy before permanent systems are considered for improved pain management.
Area of Science:
- Pain Medicine
- Oncology
- Neurosurgery
Background:
- World Health Organization (WHO) pharmacologic guidelines are standard for cancer pain but effective in only 70-90% of patients.
- A significant number of patients experience intractable cancer-related pain, with poor outcomes in terminal care.
Purpose of the Study:
- To explore intraspinal drug delivery as an alternative for cancer pain management in patients refractory to WHO guidelines.
- To outline the necessary steps for implementing intraspinal therapy, including trials for efficacy and toxicity.
Main Methods:
- Discusses interventional pain management, specifically intraspinal analgesic delivery.
- Highlights the importance of trial periods with external systems to assess efficacy, toxicity, and placebo effects.
- Differentiates between external (short-term prognosis) and totally implanted (long-term prognosis) systems.
Main Results:
- Intraspinal therapy offers an alternative for intractable cancer pain.
- Trial periods are crucial to confirm positive response and rule out adverse effects.
- Morphine is the gold standard, but other opioids and non-opioid agents (e.g., bupivacaine, clonidine) can be used.
Conclusions:
- Intraspinal drug delivery is a viable option for patients with refractory cancer pain.
- Careful patient selection and trial periods are essential for successful intraspinal therapy.
- Appropriate system selection (external vs. implanted) depends on patient prognosis and cost-effectiveness.

01:30Local Anesthetics: Clinical Application as Surface, Infiltration, and Conduction Block Anesthesia
Depending on the target organ, local anesthetics (LAs) can be administered via various routes. In surface anesthesia, LAs are applied directly to the surface of the skin or mucous membranes. It is widely used for topical skin numbing before venipuncture or minor surgical procedures. Commonly used surface local anesthetics are lidocaine or benzocaine sprays or creams. Surface anesthesia occurs within 5 minutes and lasts for about 60 minutes. One of the main disadvantages of topical anesthesia is...
01:11Local 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...
01:29Local 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...

01:16Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
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.

01:24Parenteral 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.
01:29Drug Delivery: Parenteral Route
The parenteral route is a critical method of drug administration. It delivers compounds directly into the systemic circulation and bypasses the gastrointestinal tract. This approach is particularly advantageous for drugs that exhibit poor absorption or instability when administered orally.
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...
