Effect of Intrathecal Dexamethasone on Intra-operative Hemodynamic in

Status Not yet recruiting

Clinical Trial Summary

Correction of Post-spinal anesthesia hypotension by fluids pose the risk of volume overload or compromising cardiac conditions. Intravenous Dexamethasone in some studies is used to treat conditions manifested by decrease of peripheral vascular resistance Many advantages were investigated for the addition of dexamethasone to bupivacaine in spinal anesthesia as prolongation of anesthesia time, postoperative analgesia and prophylaxis for shivering. In this study the investigators will investigate the ability of dexamethasone to blunt post-spinal anesthesia hypotension in elderly patients undergoing urological endoscopic surgery, and hence, if it decreases amount of fluids and dose of vasoactive drugs.

Clinical Trial Description

Spinal anesthesia is the most consistent block for lower abdomen and lower limb surgery. Spinal anesthesia avoids the risks of general anesthesia such as aspiration of gastric contents and difficulty with airway management. Post-spinal anesthesia hypotension in elderly patients is challenging. Correction of Post-spinal anesthesia hypotension by fluids either colloids or crystalloids or by vasoconstrictors pose the risk of volume overload or compromising cardiac conditions. Intravenous Dexamethasone in some studies is used to treat conditions manifested by decrease of peripheral vascular resistance. Many advantages were investigated for the addition of dexamethasone to bupivacaine in spinal anesthesia as prolongation of anesthesia time, postoperative analgesia and prophylaxis for shivering. Avoidance of complications of opioids is a great issue as, postoperative nausea, vomiting, respiratory depression, urinary retention, prolonged hospital stay and immunosuppression. In this study the investigators will investigate the ability of dexamethasone to blunt post-spinal anesthesia hypotension in elderly patients undergoing urological endoscopic surgery, and hence, if it decreases amount of fluids and dose of vasoactive drugs. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
