The impact of removing restraint on ICU acquired weakness,limb muscle strength and unplanned extubation in pancreatitis patients with normal cognitive function

Objective To investigate the impact of removing restraint on intensive care unit acquired weakness(ICU-AW), muscle strength and the incidence of extubation in patients with pancreatitis but normal cognitive function. Methods Eighty patients with pancreatitis but normal cognitive function hospitalized from February 2017 to November 2018 were divided into experimental group (40 cases) and control group (40 cases) by random digits table method. The control group received routine care and restraint, while the experimental group was removed from restraint compared with the control group. The Medical Research Council (MRC) score, incidence rate of ICU-AW, and extubation rate were compared between the two groups. Results The MRC scores of the experimental group before intervention, on 3rd, 7th and 10th day were (55.1±4.2), (54.2±4.6), (53.4±4.3), and (52.3±4.8) respectively. The MRC scores before the intervention, on the 3rd, 7th, and 10th day in the control group were (53.8±5.6), (52.0±6.2), (49.7±6.2), and (48.7±5.7) respectively. The MRC scores of the experimental group were significantly higher than those of the control group. The difference of MRC scores between the two groups was statistically significant on the 7th and 10th day(t=3.012, 3.060, P 0.05). There was no unplanned extubation in both groups. Conclusions The removal of restraint in patients with pancreatitis but normal cognitive function can slow down the decline in muscle strength but has no positive impact on the incidence rate of ICU-AW.
