Based on the theory of treating impotence alone with Yang Ming to explore the intervention of finger-pressing therapy on ICU-acquired weakness in critically ill children / 中国实用护理杂志

Objective:To explore the clinical feasibility of finger-pressing therapy based on the theory of treating impotence alone with Yang Ming to reduce incidence of ICU acquired weakness (ICU-AW) in critically ill children and provide a feasible nursing plan for ICU acquired asthenia in critically ill children.Methods:A quasi-experimental study was conducted. A total of 73 critically ill children were admitted to the PICU of Kunming Children′s Hospital from January 1 to April 30, 2021. According to the random number table, the subjects were divided into the observation group (37 cases) and the control group (36 cases). Children in the control group received routine PICU nursing. The children in the observation group were treated with PICU routine nursing and finger-pressing therapy based on the theory of treating impotence alone with Yang Ming. The two groups were compared in terms of limb muscle strength score (MRC-Score), incidence of ICU-AW, basic activities of life (Barthel Index, BI), limb muscle thickness.Results:After intervention, the MRC-Score of the observation group was 50 (46, 52) points, which was higher than 46 (40, 48) points of the control group, and the difference between the two groups was statistically significant ( Z=-3.70, P<0.05). The incidence of ICU-AW in the observation group was 32.43% (12/37), and the incidence of ICU-AW in the control group was 72.22% (26/36). The difference between the two groups was statistically significant ( χ2=11.58, P<0.05). The BI score of the observation group was 63 (50, 70), which was higher than 44 (40,60) of the control group, and the difference between the two groups was statistically significant ( Z=-3.94, P<0.05). The reduction degree of quadriceps femoris thickness in the observation group at D3-D1 was (-0.381 ± 0.131) cm, which was lower than (-0.762 ± 0.182) cm in the control group, and the difference between the two groups was statistically significant ( t=10.29, P<0.05). Conclusions:The application of finger-pressing therapy guided by theory of treating impotence alone with Yang Ming in the early rehabilitation of critically ill children can enhance muscle strength, prevent muscle atrophy and reduce the incidence of ICU-AW in critically ill children.

Diagnostic accuracy of muscle ultrasound and plasma monocyte chemoattractant protein-1 for ICU-acquired weakness in patients with sepsis / 中华危重病急救医学

Objective:To explore the diagnostic accuracy of muscle ultrasound and plasma monocyte chemoattractant protein-1 (MCP-1) for ICU-acquired weakness (ICU-AW) in patients with sepsis.Methods:A prospective observational study was conducted. Patients with sepsis admitted to the intensive care unit (ICU) of Henan Provincial People's Hospital from April 2021 to October 2021 were enrolled. The demographic data were collected. The enrolled patients were evaluated with Medical Research Council (MRC) score every day until discharged from ICU. During this period, patients with total MRC score < 48 (for two consecutive times and a time interval of 24 hours) were divided into ICU-AW group, those with total MRC score ≥ 48 were served as non-ICU-AW group. On the 1st, 4th and 7th day following admission into ICU, ultrasound was used to measure the muscle linear thickness of the rectus femoris (RF-MLT), the cross sectional area of the rectus femoris (RF-CSA) and the muscle linear thickness of the vastus intermedius muscle (VI-MLT). And meanwhile, the plasmas samples of patients were collected to measure MCP-1 concentration by enzyme-linked immunosorbent assay (ELISA). The difference of each index was compared between the ICU-AW group and the non-ICU-AW group. The risk factors of ICU-AW in patients with sepsis were analyzed by binary Logistic regression. Besides, receiver operator characteristic curve (ROC curve) was plotted, the diagnostic value of ultrasound parameters and plasma MCP-1 level for ICU-AW in patients with sepsis was analyzed.Results:A total of 99 septic patients were enrolled, with 68 patients in the ICU-AW group and 31 patients in the non-ICU-AW group. Compared with the patients in the ICU-AW group, the patients in the non-ICU-AW group tended to be older, and had higher sequential organ failure assessment (SOFA) score, higher acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score, higher rates of septic shock, higher blood lactic acid and lower Glasgow coma score (GCS). Binary Logistic regression analysis showed that APACHEⅡ score and septic shock were the risk factors of ICU-AW for septic patients [odds ratio ( OR) and 95% confidence interval (95% CI) were 1.310 (1.138-1.509) and 0.232 (0.072-0.746), respectively, both P < 0.05]. The RF-MLT, RF-CSA and VI-MLT on the 1st, 4th and 7th ICU day was falling over time. Compared with the patients in the ICU-AW group, the patients in the non-ICU-AW group had smaller RF-MLT on the 7th day [cm: 0.32 (0.22, 0.47) vs. 0.45 (0.34, 0.63), P < 0.05] and higher 7-day RF-CSA atrophy rate [25.85% (10.37%, 34.28%) vs. 11.65% (2.28%, 22.41%), P < 0.05]. According to ROC curve analysis, 7-day RF-MLT had diagnostic value for ICU-AW of septic patients. Area under ROC curve (AUC) was 0.688 (95% CI was 0.526-0.849); when the cut-off value was 0.41 cm, the sensitivity and the specificity were 66.7% and 68.4%. The levels of plasma MCP-1 in the ICU-AW group were significantly higher than those in the non-ICU-AW group on the 1st, 4th and 7th day. ROC curve analysis showed that the plasma MCP-1 levels on the 1st, 4th and 7th day played a significant role to diagnose ICU-AW for septic patients, the AUC and 95% CI were 0.732 (0.629-0.836), 0.865 (0.777-0.953), 0.891 (0.795-0.986), respectively. When the cut-off values were 206.3, 410.9, 239.5 ng/L, the sensitivity was 87.1%, 64.0%, 82.4%, and the specificity was 54.4%, 96.1%, 86.2%, respectively. Conclusion:The muscle mass parameters on the 7th day of bedside ultrasound and plasma MCP-1 levels had certain diagnostic values for ICU-AW in patients with sepsis.

The Chinese version of the Chelsea Critical Care Physical Assessment Tool applied in critically ill patients / 中国实用护理杂志

Objective:To explore the threshold and diagnostic value of Chinese version of the Chelsea Physical Function Assessment Tool (CPAx-Chi) for ICU acquired weakness(ICU-AW).Methods:To learn the details and precautions of the CPAx-Chi scale, and then two researchers used the CPAx-Chi scale and MRC-Score scale to independently evaluate 200 patients who come from a comprehensive ICU in a top first-class hospital in Gansu Province simultaneously. The best cut-off point and value of the CPAx-Chi scale in the diagnosis of ICU-AW were determined by calculating the Receiver Operating Characteristic (ROC) curve, the Youden index(YI) and the consistency test that are all based on the MRC-Score≤48.Results:The ROC Area Under Curve(AUC) of the CPAx-Chi scale diagnosis ICU-AW which based on the MRC-Score≤48 were as follows: ROC AUC of group A was 0.899 (95% CI 0.862-1.025); ROC AUC of group B was 0.874 (95% CI 0.824-0.925). When the best cut-off point of CPAx-Chi scale for diagnosis ICU-AW was 31.5, the maximum YI=0.643, the sensitivity was 87%, and the specificity was 77% in group A; and the maximum YI= 0.62, the sensitivity was 75%, and the specificity was 87% in group B. Meanwhile, when the best cut-off point of CPAx-Chi scale for diagnosis ICU-AW was 30.5, the maximum YI=0.62, the sensitivity was 79%, and the specificity was 83% in group B. Taking the CPAx -Chi≤31 as the best cut-off point, the score differences in ICU-AW group and the non-ICU-AW group were not detected, A group ( F value was 4.53, P=0.035) or B group ( F value was 6.51, P=0.011). The consistency of CPAx -Chi≤31 and MRC-Score≤48 in the diagnosis of ICU-AW was high, and the Kappa=0.845 ( P=0.02) in the group A; the Kappa=0.839( P=0.04) in the group B, and the group differences were detected. Conclusions:CPAx-Chi≤31 is the best cut-off point for diagnosing ICU-AW, and has good sensitivity and specificity. CPAx-Chi scale can be popularized and applied in the critical care medicine in China.

Meta-analysis of effects of neuromuscular electrical stimulation of lower limbs on patients with mechanical ventilation in intensive care unit / 中华危重病急救医学

Objective:To evaluate the effect of lower limb neuromuscular electrical stimulation (NMES) on mechanical ventilation patients in intensive care unit (ICU).Methods:Databases including the Cochrane Library, PubMed, Web of Science, Embase, SinoMed, CNKI, VIP and Wanfang database were searched from inception to May 2021. Randomized controlled trails (RCT) about the influence of NMES of lower limbs in patients with mechanical ventilation in ICU were collected. Routine rehabilitation measures were implemented in the control group, while the combination of routine rehabilitation and NMES on the lower limbs was implemented in the observation group. The literature screening, data extracting, and bias risk assessment of included studies were conducted independently by two reviewers. RevMan 5.3 software was used to perform Meta-analysis. Funnel plot was used to test publication bias.Results:A total of 8 RCT were eventually enrolled. The literature quality evaluation results showed that 1 study was grade A and 7 studies were grade B, suggesting that the quality of the included literature was relatively high. The Meta-analysis results showed that NMES in the lower extremities could effectively shorten the duration of mechanical ventilation in ICU patients [standardized mean difference ( SMD) = -0.51, 95% confidence interval (95% CI) was -0.72 to -0.31, P < 0.000 01], increase the maximum inspiratory pressure [MIP; mean difference ( MD) = 14.19, 95% CI was 9.30 to 19.09, P < 0.000 01], and improve the functional status of critically ill patients [functional status score for ICU (FSS-ICU); MD = 10.44, 95% CI was 3.12 to 17.77, P = 0.005] with statistically significances. However, there were no significant advantages in increasing the Medical Research Council (MRC) score ( MD = 2.13, 95% CI was -1.38 to 5.63, P = 0.23), reducing ICU mortality [relative risk ( RR) = 0.80, 95% CI was 0.51 to 1.24, P = 0.31], shortening length of ICU stay ( MD = -0.54, 95% CI was -3.67 to 2.59, P = 0.74), and the combined effect was not statistically significant. Funnel plot based on the duration of mechanical ventilation showed that the distribution of included articles was basically symmetrical, and no publication bias was detected. Conclusions:NMES of the lower limbs can not only shorten the ventilation duration effectively, but also improve the MIP and functional status of mechanically ventilated patients in ICU. However, it has no significant effect on the MRC score, ICU mortality and length of ICU stay of patients with mechanical ventilation. In the future, high-quality, large sample size and multi-center RCT are needed to verify the effects of NMES.

Study on pathological mechanism and establishment of animal model of ICU acquired weakness / 医学研究生学报

ObjectiveThere are few animal experiments on ICU acquired weakness (ICU AW), and suitable animal models are the main constraints. The study was to explore the method of ICU AW animal model which satisfies the clinical requirements of ICU and suitable for large-scale animal trials.MethodsThirty six SD rats were randomly divided into Control group(0.9%NS at 2.5 ml/kg intraperitoneal injection once a day for consecutive 3 days), immobilization group(the left hindlimb was immobilizated for 7d, then the immobilization was removed to 14 d), sepsis group(lipopolysaccharide at 2.5 mg/kg intraperitoneal injection once a day for consecutive 3 days) and sepsis-immobilization group(the left hindlimb was immobilizated for 7d, then the immobilization was removed to 14 d and lipopolysaccharide at 2.5 mg/kg intraperitoneal injection once a day for consecutive 3 days).To determine whether the model was successful, the muscle strength of left hindlimb, gastrocnemius/body weight ratio and pathological changes of gastrocnemius were measured at 0 d( immediately after intervention), 3d, 7 d, 10 d, 14 d. To explore the possible pathological mechanism, creatinine/body weight ratio, albumin, lymphocyte, and gastrocnemius pathological scores were measured.Results7 days later, the scores of left hindlimb muscle strength and pathology in sepsis immobilization group were significantly higher than those in the sepsis group and the control group(P<0.05), contary body weight and gastrocnemius weight were lower than those in control group, immobilization group and sepsis group(P<0.05), and gastrocnmiu/body weight ratio(0.528±0.018) was significantly lower than those in control group(0.756±0.315) and sepsis group(0.813±0.040)(P<0.05). Creatinine / body weight in sepsis immobilization group(0.283±0.0268) was significantly higher than those of blank group (0.185±0.022), immobilization group (0.207±0.027) and sepsis group (0.246±0.043)(P<0.05). The lymphocyte count [(5.193±1.493) ×109/L] was significantly lower than that in the blank group[(7.005±0.702) ×109/L] and the immobilization group[(7.208±0.832) ×109/L)](P< 0.05). 14 days later, the scores of left hindlimb muscle strength, body and gastrocnemius weight in sepsis immobilization group were significantly lower than those in control group, immobilization group and sepsis group(P<0.05). Gastrocnmiu/body weight ratio in sepsis immobilization group(0.519± 1.493) was significantly lower than those in control group(0.798±0.015), immobilization group (0.570±0.022)and sepsis group(0.693±0.022)(P<0.05).ConclusionThe qualified animal model of ICU AW can be established by repeated intraperitoneal injection in low dose of lipopolysaccharide combined with limb immobilization. Immunosuppression and Hypercatabolism in ICU AW rats is an important reason that ICU AW can not to be mitigated. Thus, we supposed that it may be the mechanisms for the development of ICU AW,which needs further experimental verification.

Objective To observe the early morbidity of ICU-acquired weakness (ICU-AW) in mechanical ventilation patients, and to analyze the risk factors and prognosis of ICU-AW. Methods A prospective cohort study was conducted. The patients undergoing mechanical ventilation admitted to intensive care unit (ICU) of Fu Xing Hospital of Capital Medical University from April 2016 to February 2017 were enrolled. The peroneal nerve test was performed on (3±1) days of mechanical ventilation, and complete neuro-electrophysiological examination was performed next on the patients with positive result of peroneal nerve test. The abnormal cases were enrolled in the observation group, others were enrolled in the control group, then the early incidence of ICU-AW was obtained. The control group reviewed the peroneal nerve test after 10 days, and the late ICU-AW incidence was obtained. Death, ICU discharge, or over 60 days of ICU stay were set to the endpoints of observation. Demographic data, basic indicators, drug usage, comorbidities and metabolic markers during the study period, outcome data were collected and analyzed, and risk factors and of early ICU-AW in mechanical ventilation patients were identified by multivariate Logistic regression analysis. Results A total of 60 patients were enrolled in the study, with 19 patients in the observation group, and 41 in the control group, with the early ICU-AW incidence of 31.7%. In the control group, 8 patients reviewed the peroneal nerve test after 10 days, of

Effects of Sufentanil Combined with Dexmedetomidine on ICU Acquired Weakness of AECOPD Patients Receiving Mechanical Ventilation / 中国药房

OBJECTIVE:To investigate the effects of sufentanil combined with dexmedetomidine on ICU acquired weakness(ICU-AW)of AECOPD patients receiving mechanical ventilation. METHODS:A total of 120 AECOPD patients in ICU of our hospital during Oct. 2015-Oct. 2016 were divided into group A and B according to random number tablet,with 60 cases in each group. Group A was given analgesia and sedation of sufentanil combined with propofol;group B was given analgesia and sedation of sufentanil combined with dexmedetomidine. RAAS sedation score and British Medical Research Committee(MRC)score were compared between 2 groups before treatment and 7 d after treatment. The incidence of ICU-AW,delirium and tracheal extubation were observed. The staying time in ICU,total hospitalization time and the occurrence of ADR were compared between 2 groups after diagnosed as ICU-AW. RESULTS:After treatment,the scores of RASS sedation degree scale in 2 groups were decreased significantly compared to before treatment,with statistical significance (P<0.05);there was no statistical significance between 2 groups(P>0.05). MRC score of group A was decreased significantly compared to before treatment,and significantly lower than group B,with statistical significance(P<0.05). There was no statistical significance in MRC score of group B before and after treatment(P>0.05). After 7 d of treatment,the incidence of ICU-AW in group B was significantly lower than group A(40.00% vs. 56.67%);the incidence of tracheal extubation in group B was significantly higher than group A(70.00% vs. 53.33%),the incidence of delirium was significantly lower than group A(13.33% vs. 20.00%);the staying time in ICU and total hospitalization time in group B after diagnosed as ICU-AW were significantly shorter than group A,with statistical significance(P<0.05). There was no statistical significance in the total incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Compared with sufentanil combined with propofol, sufentanil combined with dexmedetomide shows similar analgesia and sedation effect,but has better influence on the muscle strength of the patient,reducing the incidence of ICU-AW and delirium,shortening the duration of mechanical ventilation,staying time in ICU and total hospitalization time in AECOPD patients receiving mechanical ventilation,with similar safety.
