Parenteral khoom noj khoom haus-hais txog kev muab cov as-ham los ntawm sab nraud txoj hnyuv, xws li cov hlab ntsha, intramuscular, subcutaneous, intra-abdominal, thiab lwm yam. Txoj kev tseem ceeb yog intravenous, yog li cov khoom noj khoom haus parenteral tuaj yeem hu ua intravenous khoom noj hauv qhov nqaim.
Intravenous mov-hais txog ib txoj kev kho mob uas muab khoom noj khoom haus rau cov neeg mob los ntawm txoj hlab ntsha.
Cov muaj pes tsawg leeg ntawm parenteral as-ham - feem ntau yog qab zib, rog, amino acids, electrolytes, vitamins, thiab kab kawm.
Kev muab khoom noj khoom haus parenteral-nws txawv nrog cov neeg mob thiab cov kab mob. Cov neeg laus cov calorie ntau ntau yuav tsum yog 24-32 kcal / kg·d, thiab cov khoom noj khoom haus yuav tsum raug xam raws li tus neeg mob qhov hnyav.
Glucose, rog, amino acids thiab calories-1g qabzib muab 4kcal calories, 1g rog muab 9kcal calories, thiab 1g nitrogen muab 4kcal calories.
Qhov sib piv ntawm qab zib, rog thiab amino acid:
Lub zog zoo tshaj plaws hauv cov khoom noj khoom haus parenteral yuav tsum yog ob lub zog uas muaj suab thaj thiab rog, uas yog, tsis muaj protein ntau calories (NPC).
(1) Thaum tshav kub kub nitrogen ratio:
Feem ntau 150 kcal: 1 g N;
Thaum muaj kev ntxhov siab hnyav heev, cov khoom siv nitrogen yuav tsum tau nce ntxiv, thiab qhov sib piv ntawm cov cua sov-nitrogen tuaj yeem hloov mus rau 100kcal: 1g N kom tau raws li qhov xav tau ntawm kev txhawb nqa metabolic.
(2) Qab zib rau lipid ratio:
Feem ntau, 70% ntawm NPC yog muab los ntawm cov piam thaj thiab 30% yog muab los ntawm cov roj emulsion.
Thaum muaj kev ntxhov siab xws li kev raug mob, cov khoom siv roj emulsion tuaj yeem tsim nyog nce thiab kev noj cov piam thaj tuaj yeem txo qis. Ob leeg tuaj yeem muab 50% ntawm lub zog.
Piv txwv li: 70kg cov neeg mob, qhov feem pua ntawm cov tshuaj intravenous nutrient tov.
1. Tag nrho cov calories: 70kg × (24 — 32) kcal / kg·d = 2100 kcal
2. Raws li qhov piv ntawm qab zib rau lipid: qab zib rau lub zog-2100 × 70% = 1470 kcal
Rog rau lub zog - 2100 × 30% = 630 kcal
3. Raws li 1g qabzib muab 4kcal calories, 1g rog muab 9kcal calories, thiab 1g nitrogen muab 4kcal calories:
Qab Zib = 1470 ÷ 4 = 367.5g
Qhov hnyav = 630 ÷ 9 = 70g
4. Raws li qhov sib piv ntawm cua sov rau nitrogen: (2100 ÷ 150) × 1g N = 14g (N)
14 × 6.25 = 87.5g (cov protein)
