ABSTRACT
Nurses in intensive care units are subjected to high levels of work-related stress and must cope with psychological distress. This preliminary study explored the effects of an online supportive music and imagery intervention on these nurses' perceived stress, psychological distress, and sleep quality. A prospective pre-post design was employed to investigate the effectiveness of online supportive music and imagery interventions. The intervention comprised five weekly sessions, each lasting 50-60 min, which included verbal interactions and listening to music, and were facilitated by trained music therapists. Perceived stress and psychological distress were measured before and after the five-week program to investigate its effectiveness, and the current stress level and emotional state were measured before and after each session to explore changes over the intervention period. Sleep quality was measured weekly. In total, 29 participants completed the program. The results showed a significant decrease in perceived stress (d = 0.45, p = .045) and psychological distress (d = 0.53, p = .045) after the intervention. Regarding changes over the intervention period, the findings demonstrated a significant main effect of the number of sessions on perceived stress (p = 0.001), energy (p = 0.001), and tension (p = 0.023), whereas the effects on perceived valence and scores on the Korean version of the Insomnia Severity Index were not significant. Moreover, a significant post-session main effect was observed for all perceived stress and emotion ratings (p < 0.001). Online supportive music and imagery interventions may help reduce stress levels and enhance positive emotional states among nurses in intensive care units. Integrating self-work into supportive music imagery interventions may increase adherence to the intervention and extend its effect.
ABSTRACT
Objective: This descriptive study surveyed family caregivers of patients in intensive care units (ICUs) during the COVID-19 pandemic to examine the impact of musical listening on their psychological well-being. Method: The data collected in this study compared with collected from similar research conducted before the COVID-19 pandemic in 2017. The previous study had 195 participants, and the current study had 92. To measure the participants' psychological well-being, the Korean version of the Center for Epidemiologic Studies Depression Scale and the World Health Organization Quality of Life Scale were administered. An investigator-constructed questionnaire was also used to collect information related to participants' engagement in music activities including music listening in their everyday lives and their perceptions of music's benefits. Results: A two-way ANOVA showed significant effects for time (e.g., before vs. during COVID-19) and involvement in personal music listening (yes vs. no) on current emotional state, with family caregivers reporting significantly greater negative emotions during COVID-19 than before and personal music listening having a positive effect on perceived emotions. For quality of life there was no significant time effect, while the listening effect was statistically significant, indicating a significantly higher quality of life in the group who engaged in music listening in their everyday lives compared to the group who did not. There were no significant time or listening effects for perceived level of depression. Conclusion: Given the COVID-19 situation and the need to transition to a post-pandemic era, this study suggests that music listening can be an effective option for family caregivers to implement as a resource for attenuating emotional distress and enhancing self-care.
ABSTRACT
BACKGROUND: Since the COVID-19 pandemic, restricting family visits in the ICU has increased concerns regarding negative psychosocial consequences to patients and families. OBJECTIVES: To compare the quality of life, depressive symptoms, and emotions in family caregivers of ICU patients before and during the COVID-19 pandemic, and to explore families' perceptions and suggestions for the visitation. METHODS: A cross-sectional descriptive survey was conducted in 99 family caregivers of adult surgical ICU patients from an urban academic medical center in South Korea (February to July 2021). The WHO's Quality of Life-BREF, Center for Epidemiologic Studies Depression, and Visual Analogue Scale were used to assess quality of life, depressive symptoms, and emotions, respectively. The Family Perception Checklist was used to assess families' perceptions and suggestions about the visitation restriction. Results were compared with the data from our previous survey (n = 187) in 2017. RESULTS: Family caregivers were mostly women (n = 59), adult children (n = 43) or spouse (n = 38) of patients with mean age of 47.34 years. Family caregivers surveyed during the pandemic reported worsening sadness (54.66 ± 28.93, 45.58 ± 29.44, P = 0.005) and anxiety (53.86 ± 30.07, 43.22 ± 29.02, P = 0.001) than those who were surveyed in. While majority of families were satisfied with the visitation restrictions (86.9%), only 50.5% were satisfied with the amount of information provided on the patient's condition. CONCLUSIONS: Visitation restriction is necessary during the COVID-19 pandemic despite sadness and anxiety reported in caregivers. Hence, alternative visitation strategies are needed to mitigate psychological distress and provide sufficient information to ICU family caregivers.

Although inadequate research support for intensivists can be one major reason of the poor research productivity, no study has investigated the current research environment in critical care medicine in Asia. The objective of this study was to describe Asian academia in critical care from the research environment perspective. We conducted a cross-sectional questionnaire survey targeting all physician members of the Societies of Intensive/Critical Care Medicine in Japan, South Korea, and Singapore. We collected the characteristics of the participants and their affiliated institutions and the research environment. The outcome was the number of peer-reviewed publications. Multivariable logistic regression analyses examined the association between the outcome and the following five research environmental factors (i.e., country of the respondents, availability of secured time for research activities or research supporting staff for the hospital, practice at a university-affiliated hospital, and years of clinical practice of 10 years or longer). Four hundred ninety responded (overall response rate: 5.6%) to the survey between June 2019 and January 2020. Fifty-five percent worked for a university-affiliated hospital, while 35% worked for a community hospital. Twenty-four percent had secured time for research within their full-time work hours. The multivariable logistic model found that a secured time for the research activities [odds ratio (OR): 2.77; 95% confidence interval (CI), 1.46-5.24], practicing at a university-affiliated hospital (OR: 2.61; 95% CI, 1.19-5.74), having clinical experience of 10 years or longer (OR:11.2; 95%CI, 1.41-88.5), and working in South Korea (OR: 2.18; 95% CI, 1.09-4.34, Reference: Japan) were significantly associated with higher research productivity. Intensivists in the three countries had limited support for their research work. Dedicated time for research was positively associated with the number of research publications.
ABSTRACT
Dysfunction of mitochondrial metabolism is implicated in cellular injury and cell death. While mitochondrial dysfunction is associated with lung injury by lung inflammation, the mechanism by which the impairment of mitochondrial ATP synthesis regulates necroptosis during acute lung injury (ALI) by lung inflammation is unclear. Here, we showed that the impairment of mitochondrial ATP synthesis induces receptor interacting serine/threonine kinase 3 (RIPK3)-dependent necroptosis during lung injury by lung inflammation. We found that the impairment of mitochondrial ATP synthesis by oligomycin, an inhibitor of ATP synthase, resulted in increased lung injury and RIPK3 levels in lung tissues during lung inflammation by LPS in mice. The elevated RIPK3 and RIPK3 phosphorylation levels by oligomycin resulted in high mixed lineage kinase domain-like (MLKL) phosphorylation, the terminal molecule in necroptotic cell death pathway, in lung epithelial cells during lung inflammation. Moreover, the levels of protein in bronchoalveolar lavage fluid (BALF) were increased by the activation of necroptosis via oligomycin during lung inflammation. Furthermore, the levels of ATP5A, a catalytic subunit of the mitochondrial ATP synthase complex for ATP synthesis, were reduced in lung epithelial cells of lung tissues from patients with acute respiratory distress syndrome (ARDS), the most severe form of ALI. The levels of RIPK3, RIPK3 phosphorylation and MLKL phosphorylation were elevated in lung epithelial cells in patients with ARDS. Our results suggest that the impairment of mitochondrial ATP synthesis induces RIPK3-dependent necroptosis in lung epithelial cells during lung injury by lung inflammation.
ABSTRACT
Predicting fluid responsiveness in patients under mechanical ventilation with low tidal volume (VT) is challenging. This study evaluated the ability of carotid corrected flow time (FTc) assessed by ultrasound for predicting the fluid responsiveness during low VT ventilation. Patients under postoperative mechanical ventilation and clinically diagnosed with hypovolemia were enrolled. Carotid FTc and pulse pressure variation (PPV) were measured at VT of 6 and 10 mL/kg predicted body weight (PBW). FTc was calculated using both Bazett's (FTcB) and Wodey's (FTcW) formulas. Fluid responsiveness was defined as a ≥15% increase in the stroke volume index assessed by FloTrac/Vigileo monitor after administration of 8 mL/kg of balanced crystalloid. Among 36 patients, 16 (44.4%) were fluid responders. The areas under the receiver operating characteristic curves (AUROCs) for the FTcB at VT of 6 and 10 mL/kg PBW were 0.897 (95% confidence interval [95% CI]: 0.750-0.973) and 0.895 (95% CI: 0.748-0.972), respectively. The AUROCs for the FTcW at VT of 6 and 10 mL/kg PBW were 0.875 (95% CI: 0.722-0.961) and 0.891 (95% CI: 0.744-0.970), respectively. However, PPV at VT of 6 mL/kg PBW (AUROC: 0.714, 95% CI: 0.539-0.852) showed significantly lower accuracy than that of PPV at VT of 10 mL/kg PBW (AUROC: 0.867, 95% CI: 0.712-0.957; p = 0.034). Carotid FTc can predict fluid responsiveness better than PPV during low VT ventilation. However, further studies using automated continuous monitoring system are needed before its clinical use.
ABSTRACT
BACKGROUND: Lung transplantation (LT) is an accepted therapeutic modality for end-stage lung disease patients. Intensive care unit (ICU) readmission is a risk factor for mortality after LT, for which consistent risk factors have not been elucidated. Thus, we investigated the risk factors for ICU readmission during index hospitalization after LT, particularly regarding the posttransplant condition of LT patients. METHODS: In this retrospective study, we investigated all adult patients undergoing LT between October 2012 and August 2017 at our institution. We collected perioperative data from electronic medical records such as demographics, comorbidities, laboratory findings, ICU readmission, and in-hospital mortality. RESULTS: We analyzed data for 130 patients. Thirty-two patients (24.6%) were readmitted to the ICU 47 times during index hospitalization. At the initial ICU discharge, the Sequential Organ Failure Assessment (SOFA) score (odds ratio [OR], 1.464; 95% confidence interval [CI], 1.083-1.978; P=0.013) and pH (OR, 0.884; 95% CI, 0.813-0.962; P=0.004; when the pH value increases by 0.01) were related to ICU readmission using multivariable regression analysis and were still significant after adjusting for confounding factors. Thirteen patients (10%) died during the hospitalization period, and the number of ICU readmissions was a significant risk factor for in-hospital mortality. The most common causes of ICU readmission and in-hospital mortality were infection-related. CONCLUSIONS: The SOFA score and pH were associated with increased risk of ICU readmission. Early postoperative management of these factors and thorough posttransplantation infection control can reduce ICU readmission and improve the prognosis of LT patients.
ABSTRACT
PURPOSE: This study aimed to investigate the effects of patient-directed interactive music on saliva melatonin levels and sleep quality among postoperative elderly patients in the intensive care unit (ICU). PATIENTS AND METHODS: A total of 133 elderly patients were randomized into three groups: interactive music therapy (IMT), passive listening (PL), and the control group. The control group (n = 45) received routine medical care, while IMT and PL groups received music therapy on ICU day 1. The IMT group received up to 20 mins of interactive music sessions, including relaxation techniques. The PL group received only pre-selected relaxing music-listening for 30 mins. Saliva melatonin and cortisol levels were measured three times at 11 p.m. (preoperative, operation day, and postoperative day [POD] 1). The Richards-Campbell Sleep Questionnaire (RCSQ) and Quality of Recovery-40 questionnaire (QoR40) were administered on the preoperative day, as well as PODs 1 and 2. RESULTS: The RCSQ showed a significant improvement in the IMT group compared to the control group on POD2 (71.50 vs 56.89, p=0.012), but the QoR40 did not show any difference between groups. The quality control of the saliva sample was not available due to the immediate postoperative patient's condition, resulting in a higher dropout rate. Saliva melatonin levels on POD 1 were elevated in the IMT group compared to the control group (1.45 vs 0.04, p=0.0068). The cortisol level did not show a significant difference between groups. CONCLUSION: Single IMT intervention improved subjectively assessed short-term sleep quality in postoperative elderly patients. It is difficult to conclude whether music therapy intervention affects the level of melatonin and cortisol. TRIAL REGISTRATION: The study was registered at ClinicalTrials.Gov (number NCT03156205).
ABSTRACT
BACKGROUND: Although the use of volatile sedatives in the intensive care unit (ICU) is increasing in Europe, it remains infrequent in Asia. Therefore, there are no clinical guidelines available. This study investigates the proper initial concentration of sevoflurane, a volatile sedative that induces a Richmond agitation-sedation scale (RASS) score of -2 to -3, in patients who underwent head and neck surgery with tracheostomy. We also compared the amount of postoperative opioid consumption between volatile and intravenous (IV) sedation. METHODS: We planned a prospective study to determine the proper initial sevoflurane concentration and a retrospective analysis to compare postoperative opioid consumption between volatile sedation and propofol sedation. Patients scheduled for head and neck surgery with tracheostomy and subsequent postoperative sedation in the ICU were enrolled. RESULTS: In this prospective study, the effective dose 50 (ED50) of initial end-tidal sevoflurane concentration was 0.36% (95% confidence interval [CI], 0.20 to 0.60%), while the ED 95 was 0.69% (95% CI, 0.60 to 0.75%) based on isotonic regression methods. In this retrospective study, remifentanil consumption during postoperative sedation was significantly lower in the sevoflurane group (2.52±1.00 µg/kg/hr, P=0.001) than it was in the IV propofol group (3.66±1.30 µg/kg/hr). CONCLUSIONS: We determined the proper initial end-tidal concentration setting of sevoflurane for patients with tracheostomy who underwent head and neck surgery. Postoperative sedation with sevoflurane appears to be a valid and safe alternative to IV sedation with propofol.
ABSTRACT
Noise generated in the intensive care unit (ICU) adversely affects both critically ill patients and medical staff. Recently, several attempts have been made to reduce ICU noise levels, but reliable and effective solutions remain elusive. This study aimed to provide evidence on noise distributions in the ICU to protect patient health. For one week, we measured noise levels in isolated rooms, open units, and nursing stations in medical, surgical, and pediatric ICUs, respectively. We additionally analyzed the noise generated by medical equipment that is frequently used in ICUs. The median (interquartile range) noise exposure level (dBA) of all ICU units was 54.4 dB (51.1-57.5) over 24 h. The highest noise exposure was noted in the surgical ICU's daytime open unit at 57.6 dB (55.0-61.1). Various ICU medical devices continuously generated low-frequency noise. Mechanical noise levels ranged from a minimum of 41 dB to a maximum of 91 dB. It was also confirmed that patient-monitoring devices generated loud, high-frequency noise at 85 dB. ICU noise levels were much higher than expected. Noise reduction that focuses on behavior modification of medical staff has limited potential; instead, structural improvements should be considered to reduce the transmission of noise.

BACKGROUND: The 2016 Society of Critical Care Medicine (SCCM)/European Society of Intensive Care Medicine (ESICM) task force for Sepsis-3 devised new definitions for sepsis, sepsis with organ dysfunction and septic shock. Although Sepsis-3 was data-driven, evidence-based approach, East Asian descents comprised minor portions of the project population. METHODS: We selected Korean participants from the fever and antipyretics in critically ill patients evaluation (FACE) study, a joint study between Korea and Japan. We calculated the concordance rates for sepsis diagnosis between Sepsis-2 and Sepsis-3 criteria and evaluated mortality rates of sepsis, sepsis with organ dysfunction, and septic shock by Sepsis-3 criteria using the selected data. RESULTS: Korean participants of the FACE study were 913 (383 with sepsis and 530 without sepsis by Sepsis-2 criteria). The concordance rate for sepsis diagnosis between Sepsis-2 and Sepsis-3 criteria was 55.4%. The intensive care unit (ICU) and 28-day mortality rates of sepsis, sepsis with organ dysfunction, and septic shock patients according to Sepsis-3 criteria were 26.2% and 31.0%, 27.5% and 32.5%, and 40.8% and 43.4%, respectively. The quick Sequential Organ Failure Assessment (qSOFA) was inferior not only to SOFA but also to systemic inflammatory response syndrome (SIRS) for predicting ICU and 28-day mortality. CONCLUSIONS: The concordance rates for sepsis diagnosis between Sepsis-2 and Sepsis-3 criteria were low. Mortality rate for septic shock in Koreans was consistent with estimates made by the 2016 SCCM/ESICM task force. SOFA and SIRS were better than qSOFA for predicting ICU and 28-day mortality in Korean ICU patients.

ABSTRACT
Postoperative management after major lung surgery is critical. This study evaluates risk factors for predicting mandatory intensive care unit (ICU) admission immediately after major lung resection. We retrospectively reviewed patients for whom the surgeon requested an ICU bed before major lung resection surgery. Patients were classified into three groups. Univariable and multivariable logistic regression analyses were performed, and a clinical nomogram was constructed. Among 340 patients, 269, 50, and 21 were classified into the no need for ICU, mandatory ICU admission, and late-onset complication groups, respectively. Predictive postoperative diffusion capacity of the lung for carbon monoxide (47.2 (interquartile range (IQR) 43.3-65.7)% versus vs. 67.8 (57.1-79.7)%; p = 0.003, odds ratio (OR) 0.969, 95% confidence interval (CI) 0.95-0.99), intraoperative blood loss (400.00 (250.00-775.00) mL vs. 100.00 (50.00-250.00) mL; p = 0.040, OR 1.001, 95% CI 1.000-1.002), and open thoracotomy (p = 0.030, OR 2.794, 95% CI 1.11-7.07) were significant predictors for mandatory ICU admission. The risk estimation nomogram demonstrated good accuracy in estimating the risk of mandatory ICU admission (concordance index 83.53%). In order to predict the need for intensive care after major lung resection, preoperative and intraoperative factors need to be considered.
ABSTRACT
BACKGROUND: The objective of this study was to establish the efficacy and safety of procalcitonin (PCT)-guided antibiotic discontinuation in critically ill patients with sepsis in a country with a high prevalence of antimicrobial resistance and a national health insurance system. METHODS: In a multi-center randomized controlled trial, patients were randomly assigned to a PCT group (stopping antibiotics based on a predefined cut-off range of PCT) or a control group. The primary end-point was antibiotic duration. We also performed a cost-minimization analysis of PCT-guided antibiotic discontinuation. RESULTS: The two groups (23 in the PCT group and 29 in the control group) had similar demographic and clinical characteristics except for need for renal replacement therapy on ICU admission (46% vs. 14%; P = 0.010). In the per-protocol analysis, the median duration of antibiotic treatment for sepsis was 4 days shorter in the PCT group than the control group (8 days; interquartile range [IQR], 6-10 days vs. 14 days; IQR, 12-21 days; P = 0.001). However, main secondary outcomes, such as clinical cure, 28-day mortality, hospital mortality, and ICU and hospital stays were not different between the two groups. In cost evaluation, PCT-guided therapy decreased antibiotic costs by USD 30 (USD 241 in the PCT group vs. USD 270 in the control group). The results of the intention-to-treat analysis were similar to those obtained for the per-protocol analysis. CONCLUSION: PCT-guided antibiotic discontinuation in critically ill patients with sepsis could reduce the duration of antibiotic use and its costs with no apparent adverse outcomes.

PURPOSE: Severe sepsis is associated with functional disability among patients surviving an acute phase of infection. Efforts to improve functional impairment are important. We assessed the effects of early exercise rehabilitation on functional outcomes in patients with severe sepsis. MATERIALS AND METHODS: A prospective, single-center, case-control study was conducted between January 2013 and May 2014 at a tertiary care center in Korea. Patients with severe sepsis and septic shock were enrolled and randomized to receive standard sepsis treatment or intervention. Intervention involved early targeted physical rehabilitation with sepsis treatment during hospitalization. Participants were assessed at enrollment, hospital discharge, and 6 months after enrollment. Functional recovery was measured using the Modified Barthel Index (MBI), Functional Independence Measure (FIM), and Instrumental Activities of Daily Living (IADL). RESULTS: Forty participants (21 intervention patients) were included in an intention-to-treat analysis. There were no significant differences in baseline MBI, FIM, and IADL between groups. Intervention yielded greater improvement of MBI, FIM, and IADL in the intervention group at hospital discharge, but not significantly. Subgroup analysis of patients with APACHE II scores ≥10 showed significantly greater improvement of physical function at hospital discharge (MBI and FIM) in the intervention group, compared to the control group (55.13 vs. 31.75, p=0.048; 52.40 vs. 31.25, p=0.045). Intervention was significantly associated with improvement of MBI in multiple linear regression analysis (standardized coefficient 0.358, p=0.048). CONCLUSION: Early physical rehabilitation may improve functional recovery at hospital discharge, especially in patients with high initial severity scores.

BACKGROUND: The benefits of lung-protective ventilation (LPV) with a low tidal volume (6 mL/kg of ideal body weight [IBW]), limited plateau pressure (< 28-30 cm H2O), and appropriate positive end-expiratory pressure (PEEP) in patients with acute respiratory distress syndrome have become apparent and it is now widely adopted in intensive care units. Recently evidence for LPV in general anaesthesia has been accumulated, but it is not yet generally applied by anaesthesiologists in the operating room. METHODS: This study investigated the perception about intraoperative LPV among 82 anaesthesiologists through a questionnaire survey and identified the differences in ventilator settings according to recognition of lung-protective ventilation. Furthermore, we investigated the changes in the trend for using this form of ventilation during general anaesthesia in the past 10 years. RESULTS: Anaesthesiologists who had received training in LPV were more knowledgeable about this approach. Anaesthesiologists with knowledge of the concept behind LPV strategies applied a lower tidal volume (median (IQR [range]), 8.2 (8.0-9.2 [7.1-10.3]) vs. 9.2 (9.1-10.1 [7.6-10.1]) mL/kg; p = 0.033) and used PEEP more frequently (69/72 [95.8%] vs. 5/8 [62.5%]; p = 0.012; odds ratio, 13.8 [2.19-86.9]) for laparoscopic surgery than did those without such knowledge. Anaesthesiologists who were able to answer a question related to LPV correctly (respondents who chose 'height' to a multiple choice question asking what variables should be considered most important in the initial setting of tidal volume) applied a lower tidal volume in cases of laparoscopic surgery and obese patients. There was an increase in the number of patients receiving LPV (VT < 10 mL/kgIBW and PEEP ≥5 cm H2O) between 2004 and 2014 (0/818 [0.0%] vs. 280/818 [34.2%]; p < 0.001). CONCLUSIONS: Our study suggests that the knowledge of LPV is directly related to its implementation, and can explain the increase in LPV use in general anaesthesia. Further studies should assess the impact of using intraoperative LPV on clinical outcomes and should determine the efficacy of education on intraoperative LPV implementation.

BACKGROUND: Postoperative pressure ulcers are important indicators of perioperative care quality, and are serious and expensive complications during critical care. This study aimed to identify perioperative risk factors for postoperative pressure ulcers. METHODS: This retrospective case-control study evaluated 2,498 patients who underwent major surgery. Forty-three patients developed postoperative pressure ulcers and were matched to 86 control patients based on age, sex, surgery, and comorbidities. RESULTS: The pressure ulcer group had lower baseline hemoglobin and albumin levels, compared to the control group. The pressure ulcer group also had higher values for lactate levels, blood loss, and number of packed red blood cell (pRBC) units. Univariate analysis revealed that pressure ulcer development was associated with preoperative hemoglobin levels, albumin levels, lactate levels, intraoperative blood loss, number of pRBC units, Acute Physiologic and Chronic Health Evaluation II score, Braden scale score, postoperative ventilator care, and patient restraint. In the multiple logistic regression analysis, only preoperative low albumin levels (odds ratio [OR]: 0.21, 95% CI: 0.05-0.82; P < 0.05) and high lactate levels (OR: 1.70, 95% CI: 1.07-2.71; P < 0.05) were independently associated with pressure ulcer development. A receiver operating characteristic curve was used to assess the predictive power of the logistic regression model, and the area under the curve was 0.88 (95% CI: 0.79-0.97; P < 0.001). CONCLUSIONS: The present study revealed that preoperative low albumin levels and high lactate levels were significantly associated with pressure ulcer development after surgery.
ABSTRACT
BACKGROUND: Critically ill patients experience muscle weakness, which leads to functional disability. Both functional electrical stimulation (FES) and in-bed cycling can be an alternative measure for intensive care unit (ICU) patients who are not feasible for active exercise. The aim of this study was to examine whether FES and in-bed cycling have a positive effect on muscle mass in ICU patients. METHODS: Critically ill patients who received mechanical ventilation for at least 24 hours were included. After passive range of motion exercise, in-bed cycling was applied for 20 minutes, and FES was applied for 20 minutes on the left leg. The right leg received in-bed cycling and the left leg received both FES and in-bed cycling. Thigh circumferences and rectus femoris cross-sectional area (CSA) were assessed with ultrasonography before and after the intervention. Muscle strength was assessed by Medical Research Council scale. RESULTS: A total of 10 patients were enrolled in this study as a pilot study. Before and after the intervention, the CSA of right rectus femoris increased from 5.08 ± 1.51 cm2 to 6.01 ± 2.21 cm2 , which was statistically significant (P = 0.003). The thigh circumference was also increased and statistically significant (P = 0.006). There was no difference between left and right in regard to FES application. There is no significant change in muscle strength before and after the intervention (right and left, P = 0.317 and P = 0.368, respectively). CONCLUSIONS: In-bed cycling increased thigh circumferences rectus femoris CSA. Adding FES did not show differences.
ABSTRACT
Lung transplantation is widely accepted as the only viable treatment option for patients with end-stage lung disease. However, the imbalance between the number of suitable donor lungs available and the number of possible candidates often results in intensive care unit (ICU) admission for the latter. In the ICU setting, critical care is essential to keep these patients alive and to successfully bridge to lung transplantation. Proper management in the ICU is also one of the key factors supporting long-term success following transplantation. Critical care includes the provision of respiratory support such as mechanical ventilation (MV) and extracorporeal life support (ECLS). Accordingly, a working knowledge of the common critical care issues related to these unique patients and the early recognition and management of problems that arise before and after transplantation in the ICU setting are crucial for long-term success. In this review, we discuss the management and selection of candidates for lung transplantation as well as existing respiratory support strategies that involve MV and ECLS in the ICU setting.
