Abstract:
Objective To investigate the effect of early adequate enteral nutrition (EN) on diaphragmatic thickness and prognosis of mechanical ventilation (MV) patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) by ultrasound. Methods Sixty-two MV patients with AECOPD and feasible to receive early EN were admitted to the Department of Intensive Care Unit (ICU) of Wenling Hospital of Traditional Chinese Medicine Affiliated to Zhejiang Chinese Medical University from April 2017 to March 2018, and they were divided into an observation group and a control group according to random number table, 31 cases in each group. Besides conventional treatment, both groups started EN (EN) within 2 days, in the observation group, the EN was adequately treated, and the target calories were gradually reached within 3 days; in the control group, nourishing feeding was given, and the target calories were gradually reached after 7 days. Ultrasound was used to measure the diaphragmatic end-expiratory muscle thickness (DTee) and end-inspiratory muscle thickness (DTei) before and after treatment for 3 days, 7 days, and the diaphragmatic thickening fraction (DTF) were calculated; in addition, the MV time, ICU time of stay, 14-day success rate of off-line and incidence of ventilator associated pneumonia (VAP) were compared between the two groups. Results There were no statistical significant differences in the comparisons of age, arterial blood gas analysis and acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score etc general status, and the parameters of DTee, DTei and DTF between the two groups before treatment (all P > 0.05). No statistical significant differences in DTee were found after treatment for 3 days, 7 days and after off-line in the comparisons between the two groups (mm: 3 days was 2.69±0.12 vs. 2.68±0.15, 7 days was 2.70±0.14 vs. 2.70±0.13, off-line was 2.71±0.15 vs. 2.70±0.10, all P > 0.05); while the DTei of the two groups were decreased after treatment for 3 days of treatment, the difference between the two groups being not statistically significant (mm: 3.27±0.13 vs. 3.26±0.12, P > 0.05), but the levels of DTei in the two groups were significantly increased after treatment for 7 days and after off-line, the differences between the two groups being statistically significant (7 days: 27.26±5.25 vs. 28.74±6.39, off-line: 34.19±4.78 vs. 30.10±2.90, both P < 0.01). There was no significant difference in MV time and ICU time of stay between the two groups [MV time (days): 7.8±1.0 vs. 8.5±1.2, ICU time of stay (days): 11.4±2.6 vs. 12.1±2.8, both P > 0.05], the 14-day success rate of off-line and incidence of VAP were similar in the two groups, and the difference were not statistically significant [14-day success rate off-line: 77.42% (24/31) vs. 70.98% (22/31), incidence of VAP: 6.45% (2/31) vs. 9.68% (3/31), both P > 0.05]. Conclusion The early adequate EN therapy can improve diaphragmatic function and prognosis in MV patients with AECOPD.
