Summary
Transrectal periprostatic nerve blocks did not significantly reduce pain during rigid cystoscopy. This study found no statistically significant difference in discomfort between patients who received the nerve block and those who did not.
Area of Science:
- Urology
- Anesthesiology
- Surgical Procedures
Background:
- Periprostatic nerve blocks are used for anesthesia in prostatic surgery.
- Transrectal approaches for periprostatic nerve blocks are noted for simplicity and efficacy.
Purpose of the Study:
- To evaluate the effectiveness of a transrectal periprostatic nerve block in reducing discomfort during rigid cystoscopy.
- To compare pain levels in patients undergoing cystoscopy with and without a nerve block.
Main Methods:
- A prospective study involving 73 patients undergoing rigid cystoscopy.
- Group 1 (n=39) received transrectal periprostatic lidocaine infiltration; Group 2 (n=34) underwent cystoscopy alone.
- Pain was assessed using a visual analog scale; patient demographics and prostate size were similar between groups.
Main Results:
- The mean pain score was 3.4 for the nerve block group and 3.9 for the control group.
- The difference in pain scores between the two groups was not statistically significant.
- Patient age and prostate size were comparable, indicating similar baseline characteristics.
Conclusions:
- Transrectal periprostatic nerve block does not appear to significantly reduce pain associated with rigid cystoscopy.
- Further research may be needed to explore alternative or adjunct pain management strategies for transurethral procedures.

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...
01:30Local 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...
01:24Local Anesthetics: Differential Sensitivity of Nerve Fibers
Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...
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...
