#UPTODATE2026
#Clinical_Notes

✅Antibiotics are not routinely indicated for most patients with fever in the early postoperative periods( within the first three days after surgery)
✅ but hemodynamically unstable patients should be treated empirically with broad-spectrum antibiotics, which should be discontinued after 48 hours if no source of infection has been identified.

🛑Hypocalcemia and nephrotic syndrome
✅Hypocalcemia is common, however, due to hypoalbuminemia; this does not affect the physiologically important free (or ionized) calcium concentration.
✅Measurement of the ionized calcium concentration is generally required to confirm hypocalcemia in nephrotic patients with a low total serum calcium.

🛑 beta blockers and esophageal varices. 

🅰We do not initiate beta blockers to prevent recurrent bleeding in patients with any of the following conditions because of the risk of adverse events (eg, decreased cardiac output, increased mortality):

✅Hyponatremia (serum sodium concentration <130 mEq/L)

✅Acute kidney injury

✅Spontaneous bacterial peritonitis: Beta blocker therapy in patients with spontaneous bacterial peritonitis is associated with higher mortality risk

✅Diuretic-resistant ascites: Beta blocker therapy in patients with diuretic-resistant ascites is associated with higher mortality risk

●History of adverse effects with beta blockers: Patients with a prior history of adverse effects related to beta blockers are not candidates for therapy (eg, bronchoconstriction, heart failure, acute kidney injury)

✅Systolic blood pressure <90 mmHg

🛑Isoniazid (INH) toxicity

✅Seizure treatment with pyridoxine and benzodiazepine

✅The dose of pyridoxine is 1 g IV for every gram of INH ingested.
✅ When the quantity of INH ingested is unknown, 5 g IV may be administered to an adult and 70 mg/kg (maximum 5 g) to a child.

🛑MAP target gole in shock patients

✅During initial resuscitation, a MAP ≥65 mm Hg is a reasonable target. However, the goal should be guided by organ perfusion—if urine output improves, mental status normalizes, and lactate decreases, further MAP elevation isn’t necessary, even if it’s below 65 mm Hg.
✅Patients with chronic hypertension may benefit from a higher MAP (e.g., 80–85 mm Hg) to optimize organ perfusion
