TURP from monopolar to bipolar..TURP syndrome vanish

Monopolar TURP

The conventional gold standard for TURP was the monopolar electrode resectoscope. With the monopolar electrode, layers of prostatic tissue are resected with a cutting current transmitted through a single-limb electrode which exits the patient by way of a grounding pad.
A non-electrolyte bladder-irrigating solution is required to avoid dispersion of the electrical current as well as tissue damage at the site of prostatic resection. TURP syndrome is a potentially serious complication which can occur when a nonelectrolyte, hypoosmolar bladder-irrigating solution is used.

Bipolar TURP

Bipolar TURP electrode technology incorporates a continuous loop electrode to resect prostatic tissue of BPH. This surgical tool is designed to contain the inflow and outflow of current via the resectoscope for prostatic tissue resection. By being completely self-contained within the bipolar unit, the current is prevented from passing through the patient.

The advantage of this system is that for the bladder-irrigating solution, an electrolyte-containing solution such as normal saline can be used.

Although intravascular absorption of normal saline can occur via resected prostatic veins opened during prostatic resection, hypoosmolality and hyponatremia associated with TURP syndrome are prevented. Nevertheless, the risk of volume overload as a consequence of the bladder-irrigating solution can still occur with the bipolar TURP technique.

In a review of 16 studies conducted over a 10-year period, Issa compared the safety properties of monopolar and bipolar TURP . He found a statistically significant decrease in overall complication rate,
transfusion rate, and TURP syndrome with bipolar TURP.(1)

Anaphylaxis updates part 2- Empty Ventricle Syndrome

Patients with anaphylaxis should not suddenly sit, stand, or be placed in the upright position. Instead, they should be placed on the back with their lower extremities elevated or, if they are experiencing respiratory distress or vomiting, they should be placed in a position of comfort with their lower extremities elevated. This accomplishes 2 therapeutic goals: 1) preservation of fluid in the circulation (the central vascular compartment), an important step in managing distributive shock; and 2) prevention of the empty vena cava/empty ventricle syndrome, which can occur within seconds when patients with anaphylaxis suddenly assume or are placed in an upright position. Patients with this syndrome are at high risk for sudden death. They are unlikely to respond to epinephrine regardless of route of administration, because it does not reach the heart and therefore cannot be circulated throughout the body

Steroids In Perioperative period...The Multi-purpose Drugs

1-Steroids are not Bronchodilator ,but have well established usefulness in hyper-reactive airway. They are also said to have a permissive role for bronchodilator medication. They can be administered orally, parenterally or in aerosol form 2- Steroids have been commonly used in chemotherapy for prevention of nausea along with other anti-emetic agents . Dexamethasone was found to be highly effective when given immediately before induction rather than at the end of anesthesia . 3- Steroids do exert analgesic effects. Various routes of administration of steroids include parentral, local infiltration at operated site , as an adjuvant in nerve blocks and central-neuraxial blockade. 4 - Steroids cannot be the mainstay of therapy in anaphylaxis because of the delayed onset of action, so they are used as adjunct after initial treatment with epinephrine. 5- Steroids (Dexamethsone) are of value in reduction or prevention of cerebral edema associated with parasitic infections and neopla...
