Summary
Combining EMLA and glyceryl trinitrate ointments significantly reduced venepuncture pain and improved ease of access in day surgery patients. This combination offers a promising approach for enhancing patient comfort during needle insertion.
Area of Science:
- Anesthesiology
- Pharmacology
Background:
- Venepuncture is a common procedure causing patient discomfort and anxiety.
- Effective pain management strategies are crucial for improving patient experience in day surgery settings.
Purpose of the Study:
- To evaluate the efficacy of topical anesthetics and vasodilators in reducing venepuncture pain.
- To compare the effectiveness of EMLA, glyceryl trinitrate, their combination, and placebo for pain and ease of venepuncture.
Main Methods:
- A randomized controlled trial involving 100 fit day surgery patients.
- Application of EMLA, glyceryl trinitrate, combination, or placebo ointment to the dorsum of the hand.
- Assessment of pain scores and ease of venepuncture at induction and post-operation.
Main Results:
- The combination of EMLA and glyceryl trinitrate resulted in significantly lower pain scores.
- Easier venepuncture was reported when both EMLA and glyceryl trinitrate ointments were used.
- Pain scores were reassessed 1-2 hours post-operation.
Conclusions:
- Topical EMLA and glyceryl trinitrate combination is effective in reducing venepuncture pain.
- This combination improves the ease of venepuncture, enhancing patient comfort.
- The findings support the use of this combined topical agent for routine procedures.

01:23Local Anesthetics: Common Agents and Their Applications
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...

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...
01:29Local 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.

Nursing responsibilities before cardiac catheterization include:Assess for allergies and establish baseline health status.Before cardiac catheterization, assess the patient for allergies to contrast dye. Perform a comprehensive baseline assessment, including vital signs, heart and breath sounds, and a neurovascular assessment of the extremities, noting distal pulses, skin color, and temperature. Instruct the patient to fast for 8-12 hours before the procedure. Evaluate baseline laboratory...
