Njira yowerengera ya parenteral nutrition capacity ratio

Parenteral zakudya-amatanthauza kuperekedwa kwa zakudya kuchokera kunja kwa matumbo, monga mtsempha, intramuscular, subcutaneous, intra-mimba, etc. Njira yaikulu ndi mtsempha wa mtsempha, kotero kuti zakudya za parenteral zimatha kutchedwanso mtsempha wamagazi m'njira yopapatiza.
Kudya kwa mtsempha-kumatanthauza njira yochizira yomwe imapereka zakudya kwa odwala kudzera m'mitsempha.
Kapangidwe ka parenteral zakudya-makamaka shuga, mafuta, amino zidulo, electrolyte, mavitamini, ndi kufufuza zinthu.
Kupereka kwa parenteral zakudya - zimasiyanasiyana ndi odwala komanso matenda. Zopatsa mphamvu zama calorie za munthu wamkulu ndi 24-32 kcal/kg·d, ndipo zakudya zopatsa thanzi ziyenera kuwerengedwa potengera kulemera kwa wodwalayo.
Glucose, mafuta, amino acid ndi zopatsa mphamvu - 1g shuga amapereka 4 kcal zopatsa mphamvu, 1 g mafuta amapereka 9 kcal zopatsa mphamvu, ndi 1g nitrogen amapereka 4 kcal zopatsa mphamvu.
Chiyerekezo cha shuga, mafuta ndi amino acid:
Mphamvu yabwino kwambiri pazakudya zopatsa thanzi iyenera kukhala yapawiri mphamvu yamagetsi yopangidwa ndi shuga ndi mafuta, ndiko kuti, zopatsa mphamvu zopanda mapuloteni (NPC).

(1) Chiŵerengero cha nayitrogeni wa kutentha:
Kawirikawiri 150kcal: 1g N;
Pamene kupsinjika maganizo kwakukulu, nitrogen iyenera kuwonjezeredwa, ndipo chiŵerengero cha kutentha-nitrogen chikhoza kusinthidwa kukhala 100kcal:1g N kuti akwaniritse zosowa za kagayidwe kachakudya.

(2) Chiyerekezo cha shuga ndi lipid:
Nthawi zambiri, 70% ya NPC imaperekedwa ndi shuga ndipo 30% imaperekedwa ndi emulsion yamafuta.
Pamene kupsinjika monga kuvulala, kuperekedwa kwa emulsion yamafuta kumatha kukulitsidwa moyenera ndipo kumwa kwa glucose kumatha kuchepetsedwa. Onse angapereke 50% ya mphamvu.
Mwachitsanzo: 70kg odwala, chiwerengero cha mtsempha wa michere njira.

1. Zopatsa mphamvu zonse: 70kg×(24——32)kcal/kg·d=2100 kcal

2. Malinga ndi chiŵerengero cha shuga ndi lipids: shuga mphamvu-2100 × 70% = 1470 kcal.
Mafuta a mphamvu-2100 × 30% = 630 kcal

3. Malinga ndi 1g shuga amapereka 4kcal zopatsa mphamvu, 1g mafuta amapereka 9kcal zopatsa mphamvu, ndipo 1g nitrogen amapereka 4kcal zopatsa mphamvu:
Kuchuluka kwa shuga = 1470 ÷ 4 = 367.5g
Kulemera kwa mafuta = 630 ÷ 9 = 70g

4. Malingana ndi chiŵerengero cha kutentha kwa nayitrogeni: (2100 ÷ 150) × 1g N = 14g (N)
14 × 6.25 = 87.5g (mapuloteni)
