Effects of different types and frequencies of early rehabilitation on ventilator weaning among patients in intensive care units: A systematic review and meta-analysis

Abstract

Objective This study aimed to investigate the effects of different types and frequencies of physiotherapy on ventilator weaning among patients in the intensive care unit (ICU) and to identify the optimal type and frequency of intervention. Data sources PubMed, Cochrane Library, EMBASE, and Airiti Library. Study selection Randomized controlled trials that provided information on the dosage of ICU rehabilitation and the parameters related to ventilator weaning were included. Data extraction and management Treatment types were classified into conventional physical therapy, exercise-based physical therapy, neuromuscular electrical stimulation (NEMS), progressive mobility, and multi-component. The frequencies were divided into high (≥ 2 sessions/day or NEMS of > 60 minutes/day), moderate (one session/day, 3–7 days/week or NEMS of 30–60 minutes/day), and low (one session/day, < 3 days/week, or NEMS of < 30 minutes/day). Data synthesis Twenty-four articles were included for systematic review and 15 out of 24 articles were analyzed in the meta-analysis. Early rehabilitation, especially the progressive mobility treatment exerted an optimal effect in reducing the ventilator duration in patients in the ICU (standardized mean difference [SMD] = 0.91; 95% confidence interval [CI] = 0.23–1.58; P < 0.01). Regarding the treatment frequency, the high-frequency intervention did not result in a favorable effect on ventilator duration compared with the moderate frequency of treatment (SMD = 0.75; 95% CI = -1.13–2.64; P = 0.43). Conclusion Early rehabilitation with progressive mobility is highly recommended to decrease the ventilation duration received by patients in the ICU. Depending on clinical resources and the tolerance of patients, the frequency of interventions should reach moderate-to-high frequency, that is, at least one session per day and 3 days a week. Trial registration Registration number: PROSPERO (CRD42021243331).

Assessing the impact of early progressive mobilization on moderate-to-severe traumatic brain injury: a randomized controlled trial

“…Its primary objective is to gradually transition bedridden patients from a lying down position to a sitting upright position, aiming to enhance breathing and circulation and reduce the risk of complications related to prolonged bed rest. The emphasis of the EPUP protocol is on the process of transitioning from lying down to sitting up, whereas early mobilization encompasses a broader spectrum of physical activities focused on functional mobility [ 49 ]. Therefore, compared to the EPUP protocol, the EPM protocol used in our study may provide a wider range of motor experiences and potentially alter the sensory integration and motor modulation and execution following a TBI.…”

Outcomes of different pulmonary rehabilitation protocols in patients under mechanical ventilation with difficult weaning: a retrospective cohort study

“…Controversies in outcomes may depend on the subject eligibility criteria, content of the programs, and organization’s facilities [ 22 , 23 , 25 ]. Verceles’s study applied multimodal rehabilitation programs (MRP) for patients with PMV and ICU acquired weakness.…”
