Background: Mechanical ventilation (MV) is one of the most commonly performed procedures in PICU. The indications of MV are multiple. The management strategies also vary depending upon the diseased state, infrastructure and hospital protocols. Although benefits of MV are unquestionable, its use can also cause harm. This study was done to assess the frequency, indications, complications and immediate outcome of mechanically ventilated children, with an aim to improve management protocols and outcome.Methods: A prospective observational study of children (1 month to 13 years), needing invasive MV in PICU of a medical college. MV was initiated after assessment of indication/s. All patients were ventilated with pressure support modes. Complications and outcome were assessed. Results: Of 452 patients admitted to PICU, 72 (15.93%) needed MV. Most common indication was respiratory failure (20.83%). Mean duration of MV was 4.2±4.32 days. Mean hospital stay was 11.89±12.8 days. Of 72, 24 (33.33%) developed complication/s, commonest being laryngeal edema (11.11%). Mean duration of ventilation and hospital stay were significantly higher (p <0.01) in those who developed complication/s. The mortality rate of mechanically ventilated children was 38.89%. Initial mode of MV used was significantly associated (p <0.05) with mortality. Conclusion: Complications prolong the duration of mechanical ventilation and hospital stay. They increase mortality and health care cost in a developing country. Alternatives should be tried before starting invasive MV in children.

Abstract Background: Dexmedetomidine is an alpha 2-adrenergic receptor agonist. Apart from its sedative effects, dexmedetomidine has the potential to reduce mortality through its anti-inflammatory effect. However, the impact of dexmedetomidine on in-hospital outcomes of patients with severe burns remains unclear. Therefore, we aimed to elucidate the association between dexmedetomidine and mortality in mechanically-ventilated patients with severe burns, using a Japanese nationwide database of in-hospital patients.Methods: We included adults with severe burns (burn index ≥ 10) who were registered in the Japanese Diagnosis Procedure Combination national inpatient database from 2010 to 2018, started mechanical ventilation within 3 days of admission, and received any sedative drug (dexmedetomidine, midazolam, or propofol). One-to-one propensity score matching was performed between patients who received dexmedetomidine on the day of mechanical ventilation initiation (dexmedetomidine group) and those who did not receive dexmedetomidine (control group). The primary outcome was all-cause 30-day in-hospital mortality. Secondary outcomes were length of hospital stay and duration of mechanical ventilation in all patients and survivors.Results: Eligible patients (n = 1,888) were classified into the dexmedetomidine group (n = 371) or the control group (n = 1,517). After one-to-one propensity score matching, we compared 329 patients from each of the two groups. No significant difference was observed in 30-day mortality between patients in the dexmedetomidine and control groups (22.8% vs. 22.5%, respectively; odds ratio, 1.02; 95% confidence interval, 0.71-1.46). Moreover, there were no significant differences between patients in the dexmedetomidine and control groups in terms of the length of hospital stay or the duration of mechanical ventilation.Conclusions: We found no significant association between dexmedetomidine use and in-hospital outcomes (mortality, length of hospital stay, and length of mechanical ventilation) in mechanically-ventilated patients with severe burns. Dexmedetomidine use may not improve the above-mentioned outcomes; therefore, its selection should be based on the patient’s general condition and the target level of sedation.

Mechanical ventilation practice has changed over the past few decades, with tidal volumes (VT) decreasing significantly, especially in patients with acute lung injury (ALI). Patients without acute lung injury are still ventilated with large--and perhaps too large--VT. Studies of ventilator-associated lung injury in subjects without ALI demonstrate inconsistent results. Retrospective clinical studies, however, suggest that the use of large VT favors the development of lung injury in these patients. Side effects associated with the use of lower VT in patients with ALI seem to be minimal. Assuming that this will be the case in patients without ALI/acute respiratory distress syndrome too, the authors suggest that the use of lower VT should be considered in all mechanically ventilated patients whether they have ALI or not. Prospective studies should be performed to evaluate optimal ventilator management strategies for patients without ALI.

Mechanical ventilation is a key therapeutic modality in treatment of sick neonates. Our hospital based retro­spective study conducted at Chitwan Medical College (CMC), Nepal over the duration of 2 years, from February 2015 to January 2017, with aims to study the clinical profile, indications, complications and outcome in terms of survival in mechanically ventilated neonates. Total of 119 mechanically ventilated neonates were included in the study. Along with admission and discharge register record, all the patient’s record files were retrieved from the medical record section, necessary details were entered in a predesigned proforma and statistical analysis was done using IBM SPSS 20 software. Out of 1306 total NICU admission, total 130 were mechanically ventilat­ed, among them only 119 (9.1%) were included in the study. Majority (71.4%) were male. More than half were Preterm (51.3%) and outborn (58%). Most common indication of mechanical ventilation was sepsis followed by Birth asphyxia (BA), respiratory distress syndrome/hyaline membrane disease (RDS/HMD) and Meconium Aspiration Syndrome (MAS). Overall survival was 45(37.8%). Among the indications during the study period, the best survival observed was in birth asphyxia. Shock and Disseminated intravascular coagulation (DIC) were the two most common complications encountered during the course of ventilation. Increasing birth weight, higher gestational age and Downes Score at intubation of 6 or < 6 was associated with a better outcome. Shock, multi organ dysfunctions (MODS), and ventilator associated pneumonia (VAP) were the statistically proven individual predictors of outcome.

Background: Although pulmonary and/or critical care (P/CC) physicians perform percutaneous tracheostomy in mechanically ventilated patients, the trends, timing, and outcomes of this procedure have not been well described. This study aims to describe the trends, timing, and outcomes of this procedure. Methods: Using 5% medicare data, we retrospectively examined a cohort who had tracheostomy performed after initiation of mechanical ventilation during acute hospitalization to describe the timing of tracheostomy placement by pulmonary and/or critical care (P/CC) physicians and associated outcomes. Results: There were 4864 participants in the study cohort from 2007 to 2014. We examined the timing of tracheostomy (in days from initiation of mechanical ventilation), length of hospital stay, in-hospital death, and death within 30 days after hospital discharge. The percentage of tracheostomies performed by P/CC physicians increased significantly, from 7.2% in 2007 to 14.1% in 2014 (Cochran-Armitage test for trend, P = .001). Tracheostomies performed by P/CC physicians were more common in larger hospitals and major academic medical centers. After adjustment for baseline characteristics, the following parameters did not differ by provider: time to tracheostomy, length of hospital stay (days), in-hospital death, and death within 30 days after discharge. A tracheostomy was more likely to be performed by a P/CC physician at a larger (≥500 beds) hospital (adjusted odds ratio: 1.85, 95% confidence interval: 1.47-2.34). Conclusions: Tracheostomies are increasingly performed by P/CC physicians with similar outcomes, likely related to patient selection.

Objectives: This study aims to analyze the nosocomial infection factors in post–cardiac surgery extracorporeal membrane oxygenation (ECMO) supportive treatment (pCS-ECMO). Methods: The clinical data of the pCS-ECMO patients who obtained nosocomial infections (NI) were collected and analyzed retrospectively. Among the 74 pCS-ECMO patients, 30 occurred with NI, accounting for 40.5%; a total of 38 pathogens were isolated, including 22 strains of Gram-negative bacteria (57.9%), 15 strains of Gram-positive bacteria (39.5%), and 1 fungus (2.6%). Results: Multidrug-resistant strains were highly concentrated, among which Acinetobacter baumannii and various coagulase-negative staphylococci were the main types; NI was related to mechanical ventilation time, intensive care unit (ICU) residence, ECMO duration, and total hospital stay, and the differences were statistically significant (P < .05). The binary logistic regression analysis indicated that ECMO duration was a potential independent risk factor (OR = 0.992, P = .045, 95.0% CI = 0.984-1.000). Conclusions: There existed significant correlations between the secondary infections of pCS-ECMO and mechanical ventilation time, ICU residence, ECMO duration, and total hospital stay; therefore, hospitals should prepare appropriate preventive measures to reduce the incidence of ECMO secondary infections.

Abstract Background The effect of cytomegalovirus (CMV) reactivation on the length of mechanical ventilation and mortality in immunocompetent ICU patients requiring invasive mechanical ventilation remains controversial. The main objective of this study was to determine whether preemptive intravenous ganciclovir increases the number of ventilator-free days in patients with CMV blood reactivation. Methods This double-blind, placebo-controlled, randomized clinical trial involved 19 ICUs in France. Seventy-six adults ≥ 18 years old who had been mechanically ventilated for at least 96 h, expected to remain on mechanical ventilation for ≥ 48 h, and exhibited reactivation of CMV in blood were enrolled between February 5th, 2014, and January 23rd, 2019. Participants were randomized to receive ganciclovir 5 mg/kg bid for 14 days (n = 39) or a matching placebo (n = 37). Results The primary endpoint was ventilator-free days from randomization to day 60. Prespecified secondary outcomes included day 60 mortality. The trial was stopped for futility based on the results of an interim analysis by the DSMB. The subdistribution hazard ratio for being alive and weaned from mechanical ventilation at day 60 for patients receiving ganciclovir (N = 39) compared with control patients (N = 37) was 1.14 (95% CI from 0.63 to 2.06; P = 0.66). The median [IQR] numbers of ventilator-free days for ganciclovir-treated patients and controls were 10 [0–51] and 0 [0–43] days, respectively (P = 0.46). Mortality at day 60 was 41% in patients in the ganciclovir group and 43% in the placebo group (P = .845). Creatinine levels and blood cells counts did not differ significantly between the two groups. Conclusions In patients mechanically ventilated for ≥ 96 h with CMV reactivation in blood, preemptive ganciclovir did not improve the outcome.

Abstract Objectives This study was aimed to assess the benefits of early tracheostomy (ET) compared with late tracheostomy (LT) on postoperative outcomes in pediatric cardiac surgical patients. Design Present one is a prospective, observational study. Setting The study was conducted at a cardiac surgical intensive care unit (ICU) of a tertiary care hospital. Participants All pediatric patients below 10 years of age, who underwent tracheostomy after cardiac surgery from January2019 to december2019, were subdivided into two groups according to the timing of tracheostomy: “early” if done before 7 days or “late” if done after 7 days postcardiac surgery. Interventions ET versus LT was measured in the study. Results Out of all 1,084 pediatric patients who underwent cardiac surgery over the study period, 41 (3.7%) received tracheostomy. Sixteen (39%) patients underwent ET and 25 (61%) underwent LT. ET had advantages by having reduced risk associations with the following variables: preoperative hospital stay (p = 0.0016), sepsis (p = 0.03), high risk surgery (p = 0.04), postoperative sepsis (p = 0.001), C-reactive protein (p = 0.04), ventilator-associated pneumonia (VAP; p = 0.006), antibiotic escalation (p = 0.006), and antifungal therapy (p = 0.01) requirement. Furthermore, ET was associated with lesser duration of mechanical ventilation (p = 0.0027), length of ICU stay (LOICUS; p = 0.01), length of hospital stay (LOHS; p = 0.001), lesser days of feed interruption (p = 0.0017), and tracheostomy tube change (p = 0.02). ET group of children, who had higher total ventilation-free days (p = 0.02), were decannulated earlier (p = 0.03) and discharged earlier (p = 0.0089). Conclusion ET had significant benefits in reduction of postoperative morbidities with overall shorter mechanical ventilation, LOICUS, and LOHS, better nutrition supplementation, lesser infection, etc. These benefits may promote faster patient convalescence and rehabilitation with reduced hospital costs.

AbstractPatient–ventilator asynchrony (PVA) is commonly encountered during mechanical ventilation of critically ill patients. Estimates of PVA incidence vary widely. Type, risk factors, and consequences of PVA remain unclear. We aimed to measure the incidence and identify types of PVA, characterize risk factors for development, and explore the relationship between PVA and outcome among critically ill, mechanically ventilated adult patients admitted to medical, surgical, and medical-surgical intensive care units in a large academic institution staffed with varying provider training background. A single center, retrospective cohort study of all adult critically ill patients undergoing invasive mechanical ventilation for ≥ 12 h. A total of 676 patients who underwent 696 episodes of mechanical ventilation were included. Overall PVA occurred in 170 (24%) episodes. Double triggering 92(13%) was most common, followed by flow starvation 73(10%). A history of smoking, and pneumonia, sepsis, or ARDS were risk factors for overall PVA and double triggering (all P < 0.05). Compared with volume targeted ventilation, pressure targeted ventilation decreased the occurrence of events (all P < 0.01). During volume controlled synchronized intermittent mandatory ventilation and pressure targeted ventilation, ventilator settings were associated with the incidence of overall PVA. The number of overall PVA, as well as double triggering and flow starvation specifically, were associated with worse outcomes and fewer hospital-free days (all P < 0.01). Double triggering and flow starvation are the most common PVA among critically ill, mechanically ventilated patients. Overall incidence as well as double triggering and flow starvation PVA specifically, portend worse outcome.

Abstract Background Analgesia and sedation therapy are commonly used for critically ill patients, especially mechanically ventilated patients. From the initial nonsedation programs to deep sedation and then to on-demand sedation, the understanding of sedation therapy continues to deepen. However, according to different patient’s condition, understanding the individual patient’s depth of sedation needs remains unclear. Methods The public open source critical illness database Medical Information Mart for Intensive Care III was used in this study. Latent profile analysis was used as a clustering method to classify mechanically ventilated patients based on 36 variables. Principal component analysis dimensionality reduction was used to select the most influential variables. The ROC curve was used to evaluate the classification accuracy of the model. Results Based on 36 characteristic variables, we divided patients undergoing mechanical ventilation and sedation and analgesia into two categories with different mortality rates, then further reduced the dimensionality of the data and obtained the 9 variables that had the greatest impact on classification, most of which were ventilator parameters. According to the Richmond-ASS scores, the two phenotypes of patients had different degrees of sedation and analgesia, and the corresponding ventilator parameters were also significantly different. We divided the validation cohort into three different levels of sedation, revealing that patients with high ventilator conditions needed a deeper level of sedation, while patients with low ventilator conditions required reduction in the depth of sedation as soon as possible to promote recovery and avoid reinjury. Conclusion Through latent profile analysis and dimensionality reduction, we divided patients treated with mechanical ventilation and sedation and analgesia into two categories with different mortalities and obtained 9 variables that had the greatest impact on classification, which revealed that the depth of sedation was limited by the condition of the respiratory system.
