Assessment of effects of intra-abdominal pressure monitoring on evaluating early enteral nutrition in patients with acute pancreatitis / 中华危重病急救医学

ABSTRACT

Objective:To explore the role of intra-abdominal pressure (IAP) monitoring in evaluating the efficacy of early enteral nutrition (EN) in patients with acute pancreatitis (AP).Methods:The clinical data were collected from the AP patients in department of criticle care medicine of Baoshan Branch of Huashan Hospital Affiliated to Fudan University from July 2020 to June 2021. The patients were divided into three groups according to their treatments no gastrointestinal decompression with fasting group, gastrointestinal decompression with fasting group, gastrointestinal decompression with indwelling jejunal tube within 24 hours group. The data of white blood cell (WBC), procalcitonin (PCT), serum amylase (AMY) and IAP were analyzed before and after treatment, the initiation time oral feeding were also analyzed.Results:The decrease of WBC, PCT, AMY, and IAP in gastrointestinal decompression with indwelling jejunal tube within 24 hours group were significantly greater than those in the other groups [WBC (×10 9/L) -1.72±0.74 vs. -0.68±0.36, -1.23±86.97; PCT (μg/L) -3.14±5.19 vs. 0.06±0.48, -1.57±0.78; AMY (U) -148.43±75.89 vs. -74.85±78.84, -93.78±1.17; IAP (cmH 2O, 1 cmH 2O≈0.098 kPa) -4.82±1.66 vs. 0.36±1.32, -3.22±4.36, all P < 0.05]. There were no correlation between the changes of IAP and the changes of WBC, PCT or AMY in the non-gastrointestinal decompression with fasting group and the gastrointestinal decompression with indwelling jejunal tube within 24 hours group (all P > 0.05). The decreasing trend of IAP in patients with gastrointestinal decompression with fasting group was positively correlated with the change of AMY ( r = 0.65, P < 0.001). The initiation time of oral feeding in gastrointestinal decompression with indwelling jejunal tube within 24 hours group was significantly shorter than that in the other groups (hours 89.538 vs. 111.273, 109.714), the difference was statistically significant ( P < 0.05). Conclusions:IAP monitoring, as an emergency means of monitoring the efficacy of early EN in AP patients, has the advantages of simplicity, efficiency and rationality, which has a more objective basis than the previous empirical treatment and open oral feeding.
