Magnesium Sulfate in Combination With Dexmedetomidine As Adjuvants to Levobupivacaine

March 19, 2022 updated by: Amr Samir Wahdan, Cairo University

Evaluation of Magnesium Sulfate in Combination With Dexmedetomidine As Adjuvants to Levobupivacaine for Augmenting Analgesia and Anesthesia in Ultrasound Guided Spermatic Cord Block For Testicular Sperm Extraction Surgery

Using the spermatic cord block has been of great advantage, as it has been cost saving, efficient technique whether used inon its own or combination with a sedative or . Furthermore, it provides minimal cardiac risks, early case ambulation, satisfactory postoperative pain control, as well as a reduced hospital stay and cost. one of the major drawbacks of spermatic cord block is being a single injection technique, leading to a short postoperative analgesia duration. So, to overcome this flaw some adjuvants were proven to prolong the analgesia duration as Dexmetedomidine (Dex), and magnesium.

Detailed Description

The technique of the spermatic cord block was first described in the 1960s by Earle AS.Using the spermatic cord block has been of great advantage, as it has been cost saving, efficient technique whether used inon its own or combination with a sedative or . Furthermore, it provides minimal cardiac risks, early case ambulation, satisfactory postoperative pain control, as well as a reduced hospital stay and cost. one of the major drawbacks of spermatic cord block is being a single injection technique, leading to a short postoperative analgesia duration.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.
