Drug Delivery: Parenteral Route

Drug 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...

Local Anesthetics: Clinical Application as Epidural Anesthesia

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...

Local Anesthetics: Clinical Application as Spinal Anesthesia

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...

Additional Routes of Drug Administration

Additional Routes of Drug Administration

Choosing the appropriate route of drug administration is significantly influenced by two key factors: the therapeutic objectives and the inherent properties of the drug being used.
Administering drugs via inhalation allows for the direct delivery of gaseous, volatile substances or droplets to different parts of the respiratory tract. One of the advantages of the inhalation route is the rapid absorption of drugs into the circulatory system, which is possible because of the large surface area of...

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia

Local 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.
One of the advantages of...

Prescription, Nonprescription and Orphan Drugs

Prescription, Nonprescription and Orphan Drugs

Prescription drugs require a prescription from a medical practitioner and can only be obtained from a pharmacy. They have many applications, including treating pain, anxiety, and hypertension.
The misuse and addiction to prescription drugs is a growing problem that can affect people of all age groups, specifically teenagers. This can happen when prescription medications are used in ways not intended by the prescriber, such as taking someone else's prescription or using medication for...

Summary

One year after a law change, only 30% of Certified Registered Nurse Anesthetists (CRNAs) in Washington had prescribing authority. Many CRNAs practiced without it, highlighting challenges in adopting new scopes of practice.

Area of Science:

Nursing Practice
Pharmacology
Healthcare Policy

Background:

Washington State enacted a law in 2005 granting Certified Registered Nurse Anesthetists (CRNAs) authority to prescribe controlled substances.
One year post-implementation, a significant gap existed between the law's intent and CRNA adoption of prescriptive authority.

Purpose of the Study:

To describe the prescribing practices of Washington State CRNAs.
To characterize the workforce and practice attributes of CRNAs in Washington State.

Main Methods:

A questionnaire survey was distributed in 2006 to CRNAs licensed in Washington.
The survey targeted CRNAs residing in Washington, Oregon, and Idaho.

Main Results:

Only 41% of surveyed CRNAs possessed prescriptive authority, with 11% lacking necessary Drug Enforcement Administration (DEA) registration.
CRNAs without prescriptive authority relied on the Nurse Practice Act's "select, order and administer" provision.
Among those with prescribing authority, anesthetics were most commonly prescribed (94.7%), followed by NSAIDs (60%) and narcotic analgesics (53.3%).

Conclusions:

The study identified a low rate of CRNA prescriptive authority adoption and practice one year after legislative changes.
Barriers to CRNA prescribing and the transition to expanded scopes of practice require further investigation.
Professional and policy debates surrounding autonomous CRNA prescribing persist.
