Perioperative Care for Children With Syndromic Craniofacial Synostosis Undergoing Le Fort III Surgery: A Retrospective Cohort Study.

OBJECTIVE: To present characteristics, surgical variables, complications, and postoperative care in pediatric patients with craniofacial synostosis undergoing Le Fort III osteotomy. BACKGROUND: Craniofacial synostoses are a group of genetic syndromes that result in premature fusion of cranial and facial sutures, leading to craniofacial deformities and associated complications. Midface advancement through Le Fort III osteotomy is the most frequent surgical option for these conditions. METHODS: Retrospective monocentric cohort study including patients with syndromic craniofacial synostosis who underwent Le Fort III osteotomy between 2009 and 2022 in a specialized referral center. Data collection encompassed surgical time, blood loss, intraoperative transfusions, fluid balance, and postoperative parameters such as duration of invasive mechanical ventilation and intensive care unit (ICU) length of stay. RESULTS: Twenty-six children were included in the analysis. The median surgical time was 345 minutes (300-360), with an estimated blood loss of 15 (9.9-24) mL/kg. Patients required a median transfusion of 12.63 (7.1-24.5) mL/kg of packed red blood cells and 19.82 (11.1-33) mL/kg of fresh frozen plasma. Intraoperative fluid balance was + 12.5 (0.8-22.8) mL/kg, with a median infusion of 30.4 (23.9-38.7) mL/kg of crystalloids. All patients were transferred to the ICU after surgery to ensure a safe environment for extubation. The median duration of mechanical ventilation in the ICU was 30 (20.25-45) hours, and postoperative ICU length of stay was 2 (2-4) days, and complications were infrequent, with only one extubation failure recorded. CONCLUSION: Le Fort III osteotomy in craniofacial synostosis patients may be characterized by a complex perioperative course. A multidisciplinary approach in the care of these patients allows for minimizing complications in the perioperative phase. Further research is needed to enhance perioperative management in this unique patient population.

Physiologic Effects of ECMO in Patients with Severe Acute Respiratory Distress Syndrome.

RATIONALE: Blood flow rate affects mixed venous oxygenation (SvO2) during venovenous extracorporeal membrane oxygenation (ECMO), with possible effects on the pulmonary circulation and the right heart function. OBJECTIVES: We aimed at describing the physiologic effects of different levels of SvO2 obtained by changing ECMO blood flow, in patients with severe ARDS receiving ECMO and controlled mechanical ventilation. METHODS: Low (SvO2 target 70-75%), intermediate (SvO2 target 75-80%) and high (SvO2 target > 80%) ECMO blood flows were applied for 30 minutes in random order in 20 patients. Mechanical ventilation settings were left unchanged. The hemodynamic and pulmonary effects were assessed with pulmonary artery catheter and electrical impedance tomography (EIT). MEASUREMENTS AND MAIN RESULTS: Cardiac output decreased from low to intermediate and to high blood flow/SvO2 (9.2 [6.2-10.9] vs 8.3 [5.9-9.8] vs 7.9 [6.5-9.1] L/min, p = 0.014), as well as mean pulmonary artery pressure (34 ± 6 vs 31 ± 6 vs 30 ± 5 mmHg, p < 0.001), and right ventricle stroke work index (14.2 ± 4.4 vs 12.2 ± 3.6 vs 11.4 ± 3.2 g*m/beat/m2, p = 0.002). Cardiac output was inversely correlated with mixed venous and arterial PO2 values (R2 = 0.257, p = 0.031 and R2 = 0.324, p = 0.05). Pulmonary artery pressure was correlated with decreasing mixed venous PO2 (R2 = 0.29, p <0.001) and with increasing cardiac output (R2 = 0.378 p < 0.007). Measures of ventilation/perfusion mismatch did not differ between the three steps. CONCLUSIONS: In severe ARDS patients, increased ECMO blood flow rate resulting in higher SvO2 decreases pulmonary artery pressure, cardiac output, and right heart workload.

Extracorporeal cardio-pulmonary resuscitation in a patient with missed diagnosis of sodium nitrite intoxication.

INTRODUCTION: Critical poisoning with sodium nitrite (NaNO2) can present challenges in promptly identifying and managing acute methemoglobinemia. CASE REPORT: We report the case of an overt self-intoxication by an initially unknown agent, leading to cardiac arrest. Despite prodromal signs of cyanosis, coma, desaturation, and hypotension, methemoglobinemia went unrecognized during extracorporeal cardiopulmonary resuscitation (ECPR) as the point-of-care test failed to provide methemoglobin levels, leading to untreated methemoglobinemia. The blood flowing through the oxygenator notably maintained the same brown colour. Return of spontaneous circulation was never achieved, and the patient was declared dead after 60 min of unsuccessful resuscitation. Cause of death by means of NaNO2 voluntary ingestion was later clarified and confirmed by postmortem finding of elevated nitrite and nitrate concentration. CONCLUSIONS: This case highlights the risk of failure of ECPR in the context of cardiac arrest due to methemoglobinemia, emphasizing the critical need for prompt recognition of the causative agent and early administration of antidotes.

Pulmonary shunt in critical care: a practical approach with clinical scenarios.

BACKGROUND: Pulmonary shunt refers to the passage of venous blood into the arterial blood system bypassing the alveoli-blood gas exchange. Pulmonary shunt is defined by a drop in the physiologic coupling of lung ventilation and lung perfusion. This may consequently lead to respiratory failure. MAIN BODY: The pulmonary shunt assessment is often neglected. From a mathematical point of view, pulmonary shunt can be assessed by estimating the degree of mixing between oxygenated and deoxygenated blood. To compute the shunt, three key components are analyzed: the oxygen (O2) content in the central venous blood before gas exchange, the calculated O2 content in the pulmonary capillaries after gas exchange, and the O2 content in the arterial system, after the mixing of shunted and non-shunted blood. Computing the pulmonary shunt becomes of further importance in patients on extracorporeal membrane oxygenation (ECMO), as arterial oxygen levels may not directly reflect the gas exchange of the native lung. CONCLUSION: In this review, the shunt analysis and its practical clinical applications in different scenarios are discussed by using an online shunt simulator.

The "ZEEP-PEEP test" to evaluate the response to positive end-expiratory pressure delivered by helmet: A prospective physiologic study.

Introduction: The improvement in oxygenation after helmet application in hypoxemic patients may be explained by the alveolar recruitment obtained with positive end expiratory pressure (PEEP) or by the administration of a more accurate inspiratory fraction of oxygen (FiO2). We have designed the "ZEEP-PEEP test", capable to distinguish between the FiO2-related or PEEP-related oxygenation improvement. Our primary aim was to describe the use of this test during helmet CPAP to assess the oxygenation improvement attributable to PEEP application. Material and methods: We performed a prospective physiological study including adult critically ill patients. Respiratory and hemodynamic parameters were recorded before helmet application (PRE step), after helmet application without PEEP (ZEEP step) and after the application of the PEEP valve (PEEP step), while maintaining a constant FiO2. We defined as "PEEP responders" patients showing a PaO2/FiO2 ratio improvement ≥10% after PEEP application. Results: 93 patients were enrolled. Compared to the PRE step, PaO2/FiO2 ratio was significantly improved during helmet CPAP both at ZEEP and PEEP step (189 ± 55, 219 ± 74 and 241 ± 82 mmHg, respectively, p < 0.01). Both PEEP responders (41%) and non-responders showed a significant improvement of PaO2/FiO2 ratio after the application of helmet at ZEEP, PEEP responders also showed a significant improvement of oxygenation after PEEP application (208 ± 70 vs 267 ± 85, p < 0.01). Conclusions: Helmet CPAP improved oxygenation. This improvement was not only due to the PEEP effect, but also to the increase of the effective inspired FiO2. Performing the ZEEP-PEEP test may help to identify patients who benefit from PEEP.

The occurrence of pressure injuries and related risk factors in patients undergoing extracorporeal membrane oxygenation for respiratory failure: A retrospective single centre study.

INTRODUCTION: Limited data is available regarding the incidence of pressure injuries in patients who have undergone Extracorporeal Membrane Oxygenation (ECMO), a life-saving technique that provides respiratory support for hypoxemia that does not respond to conventional treatment. AIM: To assess the incidence of pressure injuries and identify the risk factors in Acute Respiratory Distress Syndrome patients receiving ECMO. METHODS: A retrospective observational study utilizing prospectively collected data was performed in an Italian intensive care unit, between 1 January 2012 and 30 April 2022 enrolling all consecutive patients with Acute Respiratory Distress Syndrome who underwent ECMO. RESULTS: One hundred patients were included in this study. 67 patients (67%) developed pressure injuries during their intensive care unit stay, with a median of 2 (1-3) sites affected. The subgroup of patients with pressure injuries was more hypoxic before ECMO implementation, received more frequent continuous renal replacement therapy and prone positioning, and showed prolonged ECMO duration, intensive care unit and hospital length of stay compared to patients without pressure injuries. The logistic model demonstrated an independent association between the pO2/FiO2 ratio prior to ECMO initiation, the utilization of the prone positioning during ECMO, and the occurrence of pressure injuries. CONCLUSIONS: The incidence of pressure injuries was elevated in patients with Adult Respiratory Distress Syndrome who received ECMO. The development of pressure injuries was found to be independently associated with hypoxemia before ECMO initiation and the utilization of prone positioning during ECMO. IMPLICATIONS FOR CLINICAL PRACTICE: Patients who require ECMO for respiratory failure are at a high risk of developing pressure injuries. To ensure optimal outcomes during ECMO implementation and treatment, it is vital to implement preventive measures and to closely monitor skin health in at-risk areas.

Long term outcome in patients treated with veno-venous extracorporeal membrane oxygenation: A prospective observational study.

INTRODUCTION: Over the last few decades, the use of veno-venous extracorporeal membrane oxygenation (VV-ECMO) support for severe respiratory failure has increased. AIM: This study aimed to assess the long-term outcomes of patients treated with VV-ECMO for respiratory failure. METHODS: We performed a single-centre prospective evaluation of patients on VV-ECMO who were successfully discharged from the intensive care unit of an Italian University Hospital between January 2018 and May 2021. The enrolled patients underwent follow-up evaluations at 6 and 12 months after ICU discharge. The follow-up team performed psychological and functional assessments using the following instruments: Hospital Anxiety and Depression Scale (HADS), Post-traumatic Stress Disorder Symptom Severity Scale (PTSS-10), Euro Quality Five Domains Five Levels (EQ-5L-5D), and 6-minute walk test. RESULTS: We enrolled 33 patients who were evaluated at a follow-up clinic. The median patient age was 51 years (range: 45-58 years). The median duration of VV-ECMO support was 12 (9-19) days and the length of ICU stay was 23 (18-42) days. A HADS score higher than 14 was reported in 8 (24 %) and 7 (21 %) patients at the six- and twelve-month visit, respectively. PTSS-10 total score ≥ 35 points was present in three (9 %) and two (6 %) patients at the six- and twelve-month examination. The median EQ-5L-5D-VAS was respectively 80 (80-90) and 87.5 (70-95). The PTSS-10 score significantly decreased from six to 12 months in COVID-19 survivors (p = 0.024). CONCLUSIONS: In this cohort of patients treated with VV-ECMO, cognitive and psychological outcomes were good and comparable to those of patients with Adult Respiratory Distress Syndrome (ARDS) managed without ECMO. IMPLICATIONS FOR CLINICAL PRACTICE: The findings of this study confirm the need for long-term follow-up and rehabilitation programs for every ICU survivor after discharge. COVID-19 survivors treated with VV-ECMO had outcomes comparable to those reported in non-COVID patients.

High-sensitivity analysis of clonal hematopoiesis reveals increased clonal complexity of potential-driver mutations in severe COVID-19 patients.

Whether Clonal Hematopoiesis (CH) represents a risk factor for severity of the COVID-19 disease remains a controversial issue. We report the first high- sensitivity analysis of CH in COVID-19 patients (threshold of detection at 0.5% vs 1 or 2% in previous studies). We analyzed 24 patients admitted to ICU for COVID-19 (COV-ICU) and 19 controls, including healthy subjects and asymptomatic SARS-CoV2-positive individuals. Despite the significantly higher numbers of CH mutations identified (80% mutations with <2% variant allele frequency, VAF), we did not find significant differences between COV-ICU patients and controls in the prevalence of CH or in the numbers, VAF or functional categories of the mutated genes, suggesting that CH is not overrepresented in patients with COVID-19. However, when considering potential drivers CH mutations (CH-PD), COV-ICU patients showed higher clonal complexity, in terms of both mutation numbers and VAF, and enrichment of variants reported in myeloid neoplasms. However, we did not score an impact of increased CH-PD on patient survival or clinical parameters associated with inflammation. These data suggest that COVID-19 influence the clonal composition of the peripheral blood and call for further investigations addressing the potential long-term clinical impact of CH on people experiencing severe COVID-19. We acknowledge that it will indispensable to perform further studies on larger patient cohorts in order to validate and generalize our conclusions. Moreover, we performed CH analysis at a single time point. It will be necessary to consider longitudinal approaches with long periods of follow-up in order to assess if the COVID-19 disease could have an impact on the evolution of CH and long-term consequences in patients that experienced severe COVID-19.

Noninvasive Ventilation Before Intubation and Mortality in Patients Receiving Extracorporeal Membrane Oxygenation for COVID-19: An Analysis of the Extracorporeal Life Support Organization Registry.

Bilevel-positive airway pressure (BiPAP) is a noninvasive respiratory support modality which reduces effort in patients with respiratory failure. However, it may increase tidal ventilation and transpulmonary pressure, potentially aggravating lung injury. We aimed to assess if the use of BiPAP before intubation was associated with increased mortality in adult patients with coronavirus disease 2019 (COVID-19) who received venovenous extracorporeal membrane oxygenation (ECMO). We used the Extracorporeal Life Support Organization Registry to analyze adult patients with COVID-19 supported with venovenous ECMO from January 1, 2020, to December 31, 2021. Patients treated with BiPAP were compared with patients who received other modalities of respiratory support or no respiratory support. A total of 9,819 patients from 421 centers were included. A total of 3,882 of them (39.5%) were treated with BiPAP before endotracheal intubation. Patients supported with BiPAP were intubated later (4.3 vs . 3.3 days, p < 0.001) and showed higher unadjusted hospital mortality (51.7% vs. 44.9%, p < 0.001). The use of BiPAP before intubation and time from hospital admission to intubation resulted as independently associated with increased hospital mortality (odds ratio [OR], 1.32 [95% confidence interval {CI}, 1.08-1.61] and 1.03 [1-1.06] per day increase). In ECMO patients with severe acute respiratory failure due to COVID-19, the extended use of BiPAP before intubation should be regarded as a risk factor for mortality.

Determinants of increased nursing workload in the COVID-era: A retrospective analysis of prospectively collected data.

BACKGROUND: COVID-19 is associated with increased nursing workload, therefore a high nurse-to-patient ratio would be required. AIM: To analyse difference in nursing workload, as expressed with the Nursing Activities Score (NAS), between COVID-19 patients versus control patients without COVID-19 disease (NCOVID-19 group) in an Italian Extracorporeal Membrane Oxygenation (ECMO) centre. STUDY DESIGN: Retrospective analysis of prospectively collected data, enrolling consecutive patients admitted to a general Intensive Care Unit, between 1st May 2019 and 28th February 2021. A multivariate analysis was then performed to assess if COVID-19 disease was an independent predictor of higher NAS and to assess which other factors and procedures are independently associated with increased workload. RESULTS: We enrolled 574 patients, of which 135 (24%) were in the COVID-19 group and 439 (76%) in the NCOVID-19 group. The average NAS was higher in the COVID-19 group (79 ± 11 vs. 65 ± 15, T = -10.026; p < 0.001). Prone positioning, continuous renal replacement therapy (CRRT) and ECMO were used more frequently in the COVID-19 group. A higher fraction of patients in the COVID group showed colonization from multidrug resistant bacteria. COVID-19 group had a higher duration of mechanical ventilation and longer ICU stay. The COVID-19 diagnosis was independently associated with a higher NAS. Other independent predictors of higher NAS were the use of prone positioning and continuous renal replacement therapy (CRRT). Colonization from multidrug resistant bacteria and ECMO support were not independently associated with higher NAS. CONCLUSIONS: The higher nursing workload in COVID-19 patients is mainly due to specific procedures required to treat the most hypoxemic patients, such as prone positioning. Colonization with multidrug resistant bacteria and ECMO support were not independently associated with a higher NAS. RELEVANCE TO CLINICAL PRACTICE: Higher workload in COVID-19 patients was due to specific interventions, such as prone positioning and CRRT, with the related nursing activities, as continuous presence at patient's bed, mobilization, positioning and complex hygienic procedures.

Patients' recollections of helmet-CPAP treatment during COVID-19 pandemic: A qualitative study.

BACKGROUND: During the pandemic outbreak, helmet continuous positive airway pressure (CPAP) was widely used as respiratory support for COVID-19 patients, inside and outside of intensive care units. The available literature suggests specific interventions to improve the comfort of patients treated with helmet-CPAP. Few reports are available on the experiences of patients undergoing this treatment. AIM: This qualitative study aimed to explore the views and recollections of COVID-19 patients undergoing helmet-CPAP. STUDY DESIGN: We conducted semi-structured interviews with thematic analysis. Participants were recruited from the follow-up programme for COVID-19 patients discharged from an Italian general intensive care unit. Participants were interviewed by telephone. Data analysis followed the principles of thematic synthesis approach. FINDINGS: We conducted 29 phone calls in patients eligible for the study. Five participants declared that they did not remember the time spent in hospital on helmet-CPAP. Twenty-four patients were then included. Two themes and six subthemes were generated from their interview data: (1) The helmet-CPAP as a life-saving treatment (subthemes: recognition of the usefulness of treatment and resilience); (2) the negative feelings related to helmet-CPAP application (subthemes: communication problems, entrapment, mental confusion, fear of dying). Each patient's experience was unique, but some discomfort elements such as noise, gas flow turbulence, choking sensation and thirst were found to be very common. CONCLUSIONS: The application of helmet-CPAP treatment generated positive and negative memories and feelings in COVID-19 patients during the pandemic. The patients' experience has provided an overview of the main factors of discomfort. This can be a starting point for taking corrective measures to promote greater helmet tolerance and subsequent treatment success. RELEVANCE TO CLINICAL PRACTICE: This study has provided an insight into the patient's recollections about helmet-CPAP treatment during a worldwide pandemic. The findings suggested strict applications of interventions aimed to reduce some issues that participants reported, to improve their compliance to treatment. Results from this study could help nurses in understanding the needs of patients treated with helmet-CPAP and may foster a care focused on patient-centred outcomes.

Anticoagulation and Bleeding during Veno-Venous Extracorporeal Membrane Oxygenation: Insights from the PROTECMO Study.

Rationale: Definitive guidelines for anticoagulation management during veno-venous extracorporeal membrane oxygenation (VV ECMO) are lacking, whereas bleeding complications continue to pose major challenges. Objectives: To describe anticoagulation modalities and bleeding events in adults receiving VV ECMO. Methods: This was an international prospective observational study in 41 centers, from December 2018 to February 2021. Anticoagulation was recorded daily in terms of type, dosage, and monitoring strategy. Bleeding events were reported according to site, severity, and impact on mortality. Measurements and Main Results: The study cohort included 652 patients, and 8,471 days on ECMO were analyzed. Unfractionated heparin was the initial anticoagulant in 77% of patients, and the most frequently used anticoagulant during the ECMO course (6,221 d; 73%). Activated partial thromboplastin time (aPTT) was the most common test for monitoring coagulation (86% of days): the median value was 52 seconds (interquartile range, 39 to 61 s) but dropped by 5.3 seconds after the first bleeding event (95% confidence interval, -7.4 to -3.2; P < 0.01). Bleeding occurred on 1,202 days (16.5%). Overall, 342 patients (52.5%) experienced at least one bleeding event (one episode every 215 h on ECMO), of which 10 (1.6%) were fatal. In a multiple penalized Cox proportional hazard model, higher aPTT was a potentially modifiable risk factor for the first episode of bleeding (for 20-s increase; hazard ratio, 1.07). Conclusions: Anticoagulation during VV ECMO was a dynamic process, with frequent stopping in cases of bleeding and restart according to the clinical picture. Future studies might explore lower aPTT targets to reduce the risk of bleeding.

A Mortality Prediction Score for Patients With Veno-Venous Extracorporeal Membrane Oxygenation (VV-ECMO): The PREDICT VV-ECMO Score.

Mortality prediction for patients with the severe acute respiratory distress syndrome (ARDS) supported with veno-venous extracorporeal membrane oxygenation (VV-ECMO) is challenging. Clinical variables at baseline and on day 3 after initiation of ECMO support of all patients treated from October 2010 through April 2020 were analyzed. Multivariate logistic regression analysis was used to identify score variables. Internal and external (Monza, Italy) validation was used to evaluate the predictive value of the model. Overall, 272 patients could be included for data analysis and creation of the PREDICT VV-ECMO score. The score comprises five parameters (age, lung fibrosis, immunosuppression, cumulative fluid balance, and ECMO sweep gas flow on day 3). Higher score values are associated with a higher probability of hospital death. The score showed favorable results in derivation and external validation cohorts (area under the receiver operating curve, AUC derivation cohort 0.76 [95% confidence interval, CI, 0.71-0.82] and AUC validation cohort 0.74 [95% CI, 0.67-0.82]). Four risk classes were defined: I ≤ 30, II 31-60, III 61-90, and IV ≥ 91 with a predicted mortality of 28.2%, 56.2%, 84.8%, and 96.1%, respectively. The PREDICT VV-ECMO score suggests favorable performance in predicting hospital mortality under ongoing ECMO support providing a sound basis for further evaluation in larger cohorts.

Gas Humidification During Helmet Continuous Positive Airway Pressure: A Crossover Randomized Physiologic Study in Healthy Subjects.

BACKGROUND: In the last decades, the use of the helmet interface to deliver noninvasive respiratory support has steadily increased. When delivering oxygen therapy, conditioning of inspired gas is mandatory, as the water content of medical gas is neglectable. To minimize the risk of airway damage, it is recommended to achieve an absolute humidity greater than 10 mg H2O/L. The primary aim of the study was to assess the performance of 3 different heated humidifiers to condition gas during helmet continuous positive airway pressure and to compare them with a setting without active humidification. METHODS: We performed a crossover randomized physiological study in healthy volunteers. Absolute humidity, relative humidity, and temperature were measured during 4 steps (no humidification and the 3 heated humidifiers, performed in a randomized order) and at 3 time points (after 1, 5, and 10 minutes). RESULTS: Eight subjects participated to the study. Without active humidification, absolute humidity was constantly below the recommended level. All humidifiers conditioned the inspired gases to an average absolute humidity greater than 10 mg H2O/L. Overall, the best performance, in terms of absolute humidity, was obtained with H900 (19.74 ± 0.50 mg H2O/L), followed by TurbH2O (-6.82 mg H2O/L vs H900; 95% confidence interval, -8.49 to -5.14; P < .05) and F&P 810 (-9.03 mg H2O/L vs H900; 95% confidence interval, -10.70 to -7.35; P < .05). CONCLUSIONS: Active humidification is required to achieve adequate conditioning of inspired gas during helmet continuous positive airway pressure. The choice between different humidifiers available on the market should be made according to the local needs and expertise.

Airway Closure in Patients With Cardiogenic Pulmonary Edema as a Cause of Driving Pressure Overestimation: The "Uncorking Effect".

Airway closure is an underestimated phenomenon reported in hypoxemic respiratory failure under mechanical ventilation, during cardiac arrest, and in patients who are obese. Because airway and alveolar pressure are not communicating, it leads to an overestimation of driving pressure and an underestimation of respiratory system compliance. Airway closure also favors denitrogenation atelectasis. To date, it has been described mainly in patients with ARDS and those with obesity. We describe three cases of airway closure in patients with hydrostatic pulmonary edema caused by cardiogenic shock, highlighting its resolution in a limited period of time (24 h) as pulmonary edema resolved. The waveforms show a biphasic reopening that we refer to as the "uncorking effect". The detection of airway closure may require setting positive end-expiratory pressure at or above the airway opening pressure to avoid the overestimation of driving pressure.

The role of intensive care unit diaries in the grieving process: A monocentric qualitative study.

BACKGROUND: The growing importance of psychological recovery for patients and their families following intensive care unit (ICU) experiences in recent years cannot be overemphasized. The ICU diary is used to aid patients in reducing the prevalence of post-traumatic stress disorder, anxiety, and depression. The usefulness of maintaining a diary during the grieving process has not yet been thoroughly investigated. AIM: To investigate the role of ICU diaries in the grief process experienced by family members of a person who died in the intensive care unit. STUDY DESIGN: Nine family members of seven deceased ICU patients with an ICU diary were contacted and interviewed by phone using a semi-structured interview. A qualitative data analysis was performed using thematic synthesis. SETTING: Italian general intensive care unit. FINDINGS: Interviewed family members felt that the diary helped them during the grieving process. The return of diaries was desired by family members for support and to remember one's loved one. The diary helped them process their losses in various ways, including signs of evidence of care, emotional involvement, consideration, and coping with grief. Four main themes emerged from the analysis: writing the diary, reading the diary, talking about the diary, and the diary during the grieving process. CONCLUSIONS: The overall perception of the ICU diary was positive. The diary mostly helped relatives to "give back something of what we lost". This study also affirms the positive link between ICU diaries and bereavement in Italian ICU. Further studies are required to confirm the usefulness of this tool in the grieving process. RELEVANCE TO CLINICAL PRACTICE: The ICU diary can help patients' family members understand what happened to their loved one and play an important role in the grieving process. The diary served as a valuable source of information that aided in providing bereavement support to the family by helping them to gain a rational and emotional understanding of the patient's death.
