TURP was done in an old pt. of BHP, after which he developed altered sensorium cause is –
**Core Concept**
The question is testing the understanding of a potential complication of Transurethral Resection of the Prostate (TURP), a surgical procedure commonly performed to treat Benign Prostatic Hyperplasia (BPH). The underlying principle involves the risk of fluid overload and electrolyte imbalance.
**Why the Correct Answer is Right**
During TURP, a significant amount of irrigation fluid is used to visualize the surgical site. In elderly patients, the ability to manage fluid shifts and regulate electrolytes may be impaired, leading to fluid overload and subsequent cerebral edema. This can cause altered sensorium, manifesting as confusion, disorientation, or even coma. The pathophysiology involves the disruption of the blood-brain barrier, allowing fluid and electrolytes to accumulate in the brain, leading to increased intracranial pressure and potentially life-threatening complications.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is not directly related to the complication of TURP and altered sensorium. While it's true that infection can occur after any surgical procedure, it's not the primary cause of altered sensorium in this scenario.
* **Option B:** This option is incorrect because myocardial infarction is not a direct consequence of fluid overload or electrolyte imbalance following TURP.
* **Option C:** This option is incorrect because pulmonary edema can occur due to fluid overload, but it's not the most direct cause of altered sensorium in this scenario.
**Clinical Pearl / High-Yield Fact**
Remember the "3Fs" of TURP syndrome: Fluid overload, Electrolyte imbalance, and Cerebral edema. This mnemonic can help you recall the key components of this potentially life-threatening complication.
**Correct Answer: B. Myocardial infarction is not a direct consequence of fluid overload or electrolyte imbalance following TURP.
