    Abstract:

Abstract [EN]   - INTRODUCTION: : This is a study evaluating the effect of Indirect calorimetry on the length of stay. The study comprises of the comparison between the use of indirect calorimetry versus usual care in critically ill mechanically ventilated patients with respect to the length of stay in the intensive care unit, and duration of time on ventilator. Patients were divided on basis of their nutrition risk to study the effect of Indirect calorimetry on the length of stay. MATERIAL AND METHODS: This was a retrospective cohort study of 166 mechanical ventilated patients in S .L Raheja Hospital. Data was collected from 83 patients who were mechanically ventilated between January 2019 and November 2019 on whom indirect calorimetry was used to measure energy requirements. This cohort was compared to 83 patients between January 2018 and November 2918 where the energy requirements were calculated with the use of predictive equations. Both groups were matched for age, sex, comorbidities, APACHE score and use of vasopressors. RESULTS: Significant difference in the sicker group of patients was seen in the Length of stay in the intensive care unit. (9.23 ± 8.14 vs. 11.52 ± 5.65, p = 0.0034) Patients at risk for malnutrition demonstrated reduced length of time on ventilation as compared to those not at risk. (10.2 ± 11.01 vs. 13 ± 5.87; p = 0.0042). CONCLUSIONS: The use of indirect calorimetry may be associated with a lower length of ICU stay among ventilated patients in a reasonably sick group of mixed surgical patients.

Streszczenie [PL]   - WSTĘP: Badanie ocenia wpływ kalorymetrii pośredniej na długość hospitalizacji. Badanie polega na porównaniu zastosowania kalorymetrii pośredniej i zwykłej opieki u krytycznie chorych wentylowanych mechanicznie pacjentów pod względem długości pobytu na oddziale intensywnej terapii i czasu pod respiratorem. Pacjentów podzielono na podstawie ryzyka żywieniowego, aby zbadać wpływ kalorymetrii pośredniej na długość pobytu. MATERIAŁ I METODY: Było to retrospektywne badanie kohortowe 166 pacjentów wentylowanych mechanicznie w szpitalu S.L Raheja. Dane zebrano od 83 pacjentów wentylowanych mechanicznie między styczniem 2019 a listopadem 2019, u których zastosowano kalorymetrię pośrednią do pomiaru zapotrzebowania na energię. Kohortę tę porównano z 83 pacjentami w okresie od stycznia 2018 do listopada 2918 roku, u których zapotrzebowanie na energię obliczono za pomocą równań predykcyjnych. Obie grupy dobrano pod względem wieku, płci, chorób współistniejących, wyniku w skali APACHE i stosowania leków wazopresyjnych. WYNIKI: Istotną różnicę w grupie chorych z cięższą chorobą zaobserwowano w długości pobytu na oddziale intensywnej terapii (9,23 ± 8,14 vs. 11,52 ± 5,65, p = 0,0034). Pacjenci zagrożeni niedożywieniem wykazywali krótszy czas wentylacji w porównaniu z osobami bez ryzyka (10,2 ± 11,01 vs. 13 ± 5,87; p = 0,0042). WNIOSKI: Zastosowanie kalorymetrii pośredniej może wiązać się z krótszym czasem pobytu na OIT wśród pacjentów wentylowanych w grupie o umiarkowanym przebiegu chirurgii mieszanej.
