Troponin, BNP, Anzim Fwa ak Laktat

🧠 Poukisa sa enpòtan

TROPONIN se makè ki pi espesifik pou domaj myokad la: li kòmanse monte nan kèk èdtan apre domaj la, li rive nan pik li apeprè 12 a 24 èdtan epi li rete wo pandan apeprè yon semenn oswa plis, kidonk yo pran nivo an seri; CK-MB monte epi desann pi vit epi li ede detekte reyenfaktis. BNP (B-type natriuretic peptide) monte lè vantrikil yo etire; depase apeprè 100 pg/mL sipòte yon dyagnostik ensifizans kadyak, epi nivo ki pi wo swiv gravite a. Anzim FWA AST ak ALT monte ak domaj epatoselilè (epatit, alkòl, toksisite acetaminophen, statins); ALKALINE PHOSPHATASE ak GGT monte ak obstriksyon bilyè; BILIRUBIN total nòmal rive apeprè 1.2 mg/dL, epi lajònis vizib konn parèt depase apeprè 2 a 3 mg/dL; AMMONIA monte nan ensifizans fwa epi li lakòz ansefalopati epatik, yo trete l ak lactulose pou pwodwi 2 a 3 poupou mou pa jou; yon ALBUMIN ki ba ak yon PT ki pwolonje reflete fonksyon sentetik ki pèdi. AMYLASE ak LIPASE monte nan pankreatit, epi lipase se sa ki pi espesifik la. LACTATE depase 2 mmol/L endike ipoperfizyon tisi; 4 oswa plis nan sepsis yo sispèk deklanche bolus likid la. LIPID: kolestewòl total anba 200, LDL anba 100, HDL depase 40 pou gason ak 50 pou fanm, trigliserid anba 150. TSH apeprè 0.4 a 4.0 mU/L: TSH ki wo vle di hypothyroidism (pitwitè a ap rele), TSH ki ba vle di hyperthyroidism.

TROPONIN is the most specific marker of myocardial injury: it begins rising within a few hours of injury, peaks around 12 to 24 hours and stays elevated for about a week or more, so serial levels are drawn; CK-MB rises and falls faster and helps detect reinfarction. BNP (B-type natriuretic peptide) rises when the ventricles stretch; above about 100 pg/mL supports a diagnosis of heart failure, and higher levels track severity. LIVER enzymes AST and ALT rise with hepatocellular injury (hepatitis, alcohol, acetaminophen toxicity, statins); ALKALINE PHOSPHATASE and GGT rise with biliary obstruction; normal total BILIRUBIN is up to about 1.2 mg/dL, and visible jaundice usually appears above about 2 to 3 mg/dL; AMMONIA rises in liver failure and causes hepatic encephalopathy, treated with lactulose to produce 2 to 3 soft stools a day; a low ALBUMIN and a prolonged PT reflect lost synthetic function. AMYLASE and LIPASE rise in pancreatitis, and lipase is the more specific. LACTATE above 2 mmol/L indicates tissue hypoperfusion; 4 or more in suspected sepsis triggers the fluid bolus. LIPIDS: total cholesterol under 200, LDL under 100, HDL above 40 for men and 50 for women, triglycerides under 150. TSH about 0.4 to 4.0 mU/L: high TSH means hypothyroidism (the pituitary is shouting), low TSH means hyperthyroidism.

🏥 Nan lavi reyèl

🧠 Yon pasyan ki gen siwòz vin konfi epi li bat men l yo lè li kenbe yo pwolonje (asterixis). Ammonia a se 142 mcg/dL (nòmal apeprè 15 a 45 mcg/dL). Enfimyè a bay lactulose yo te òdone a epi li titre l rive de oswa twa poupou mou pa jou, pandan l ap veye dezidratasyon ak hypokalemia tretman anplis lakòz. Konfizyon lakay yon pasyan siwotik se ammonia jiskaske yo pwouve kontrè a.

🧠 A client with cirrhosis becomes confused and flaps his hands when he holds them out (asterixis). The ammonia is 142 mcg/dL (normal about 15 to 45 mcg/dL). The nurse gives the ordered lactulose and titrates it to two or three soft stools a day, watching for the dehydration and hypokalemia that overtreatment causes. Confusion in a cirrhotic client is ammonia until proven otherwise.

📌 Sa pou retni

• Troponin monte nan èdtan epi li rete wo pandan jou: repete lTroponin rises in hours and stays up for days: repeat it
• Lipase bat amylase pou pankreatit; ammonia esplike konfizyon nan ensifizans fwaLipase beats amylase for pancreatitis; ammonia explains confusion in liver failure
• TSH ak òmòn tiwoyid deplase nan direksyon opozeTSH and thyroid hormone move in opposite directions
