Critical care medicine is a multidisciplinary and interprofessional specialty committed to the comprehensive management of patients with or at risk of developing acute,life-threatening organ dysfunction.Over the years,the field has faced the significant challenge of the heterogeneity of various critical syndromes,which has led to repeated setbacks in randomized controlled trials in the study of related diseases,making it difficult to identify effective treatments through population-based efficacy exploration.This review explores how the deep integration of multi-omics data and phenotypes has brought new opportunities for developing critical care medicine.This integration can reveal the molecular mechanisms and clinical characteristics of essential syndromes in an all-round and multi-dimensional manner,accurately identify the pathophysiological differences among different patient subgroups,and thus provide a solid and reliable basis for formulating individualized treatment plans.This not only effectively solves the problem of heterogeneity,but also significantly improves the therapeutic effects and prognosis,promoting the development model of the critical care medicine discipline to shift from the traditional population-based therapeutic effect exploration model to the individualized precision medical model.Looking to the future,critical care medicine will rely more on multi-omics technologies and big data analysis and is expected to achieve precise diagnosis and treatment management for critically ill patients,further improving the diagnostic and therapeutic level of critical care medicine and bringing more hope and blessings to critically ill patients.

The paradigm shift opens a new era of neuroendocrine modulation in critical medicine
Qinghong Zhang, Min Zhou
中华重症医学电子杂志. 2025, (02):  174-178.  DOI: 10.3877/cma.j.issn.2096-1537.2025.02.014

The neuroendocrine regulatory paradigm of critical medicine has undergone revolutionary changes,from the “stress-related one-phase activation” model to the “ disease course related biphase response”model,from the “central one-way linear regulation” model to the “peripheral adaptive response” model,and from the “two- axes parallel activation” of the hypothalamic-pituitary-adrenal axis and sympathetic-adrenal medullary system to the “interactive feedback effect of the two axes” model,from the “neuroendocrine regulation” model to the “neuroimmune endocrine regulation” model.Correspondingly,the neuroendocrine regulation strategy is more inclined towards central intervention.On the one hand,it combines the replacement therapy of hypothalamic and pituitary hormones to avoid the negative feedback effect of peripheral hormones on the central nervous system and the inhibitory effects on the immune system in critical illness.On the other hand,through central or peripheral neural stimulation,not only the neuroendocrine function is improved,but also the immune function of patients can be enhanced.At present,with the assistance of new technologies (such as artificial intelligence),personalized and precise neuroendocrine regulation strategies need to be provided for clinical practice.

Objective

To develop a nomogram prediction model for weaning failure in mechanically ventilated critical ill patients in plateau areas.

Methods

A total of 255 patients requiring invasive mechanical ventilation admitted to the ICU of the People's Hospital of Xizang Autonomous Region between January 1 and December 31,2023,were enrolled.Based on weaning outcomes,patients were divided into a successful weaning group (184 cases) and a failed weaning group (71 cases).Demographic characteristics,comorbidities,vital signs,and organ function parameters were collected and compared between the two groups.Statistically significant variables in univariate analysis were incorporated into multivariate logistic regression to identify independent risk factors for weaning failure.And a nomogram prediction model for weaning failure was established.

Results

Compared with the successful weaning group,the failed weaning group had significantly longer ICU stays,higher hospitalization costs,and increased 28-day mortality (all P<0.001).The multivariate regression analysis identified three independent risk factors for weaning failure:tidal volume (Vt) before weaning (P<0.001,95%CI:0.979-0.992),respiratory rate (RR) before weaning(P=0.006,95%CI:1.034-1.218),and fluid balance in 24 hours before weaning (P=0.033,95%CI:1.000-1.001).The area under the ROC curve of the prediction model was 0.883 (95%CI:0.841-0.925).

Conclusions

Vt,RR,and 24-hour fluid balance levels before weaning significantly influence the incidence of weaning failure in mechanically ventilated critically ill patients in plateau areas.The nomogram prediction model developed for weaning failure in this study based on these three parameters,demonstrates a good predictive value.

Jin Lin, Chenlong Zhao, Zhilin Yue, Meili Duan
中华重症医学电子杂志. 2025, (02):  186-192.  DOI: 10.3877/cma.j.issn.2096-1537.2025.02.016
Abstract ( )   HTML ( )   PDF (1145KB) ( )   Save

Objective

To identify risk factors associated with 48-hour mortality following continuous renal replacement therapy (CRRT) initiation in patients with septic associated acute kidney injury(SAKI),and evaluate their predictive value for early mortality.

Methods

A retrospective cohort study of 258 SAKI patients who received CRRT in the Intensive Care Medicine Department of Beijing Friendship Hospital,Capital Medical University,between January 2016 and December 2021 was conducted.Patients were divided into survival group (203 cases) and non-survival group (55 cases) based on 48-hour mortality after CRRT initiation.Logistic regression was used to assess the risk factors for early mortality,and develop a composite predictor.Receiver operating characteristic (ROC) curve analysis was employed to assess the predictive performance of the combined prediction factor for early mortality.

Results

The 48-hour mortality rate was 21.3%.Multivariate logistic regression analysis revealed three independent risk factors for early death:lower creatinine levels [OR=1.50 (per 100 μmol/L decrease),95% CI:1.15-1.95],decreased oxygenation index[OR=1.05 (per 10 mmHg decrease),95% CI:1.02-1.09],and elevated lactate levels [OR=1.20 (per 1 mmol/L increase),95% CI:1.10-1.30].The composite predictor showed an AUC of 0.804.

Conclusions

The low levels of creatinine and oxygenation index,as well as high lactate levels in critically ill SAKI patients receiving CRRT,significantly influence the early mortality.The derived composite predictor demonstrates clinically meaningful performance for early mortality risk stratification.
