Midwakh-Associated Acute Lung Injury (MALI) in a 14-Year-Old Male: A Case Report.

Midwakh is one of the most used alternative tobacco products (ATPs) in the UAE, particularly among adolescents. We report a 14-year-old adolescent male, who presented with acute lung injury within 24 hours following the first attempt at Midwakh smoking. A high-resolution computerized tomogram of the chest (HRCT) showed bilateral interstitial pneumonia and patchy consolidation. Flexible bronchoscopy revealed bilateral petechial haemorrhages with oedematous bronchial walls. Mechanical ventilation was required for two weeks. The criteria for moderate acute respiratory distress syndrome (ARDS) were met, and a good response was achieved to a high dose of steroids, and ultra-protective mechanical ventilation with the prone position. Significant clinical and radiological recovery was achieved at three months. As per the literature reviewed, this is the first case of Midwakh-associated acute lung injury reported to date. We emphasize that physicians should be well informed about the use of ATPs and their potential severe complications.

Neonatal extra corporeal membrane oxygenation.

Extracorporeal life support (ECLS) has been proven to be very useful in the neonatal period. For reversible respiratory and cardiac disorders, when maximal conventional measures have failed to provide life support, extracorporeal membrane oxygenation (ECMO) becomes the treatment of choice. The indications, contra-indications for ECMO, optimization of the care prior to embracing ECMO, cannulation techniques, daily management of ECMO from the practical standpoint, weaning and decannulation, complications, and special circumstances in neonatal period have been described. The follow-up of neonatal ECMO and various system manifestations necessitating careful review will be highlighted.

Extracorporeal Cardiopulmonary Resuscitation in Indian Scenario: A Web-based Survey.

BACKGROUND: Practice and knowledge of extracorporeal cardiopulmonary resuscitation (ECPR) in an Indian setting is not known. The etiology could be multifactorial, such as lack of awareness, lack of facilities, and lack of finances. Unless we identify and rectify the underlying problems, utilization of this aspect of extracorporeal membrane oxygenation (ECMO) support would be difficult. MATERIALS AND METHODS: This cross-sectional observational study was done over 6 months in three phases: (A) Formation of questionnaire/tool kit by Delphi method for 1 month (July 2019), (B) circulation of questionnaire to participants in the form of Google Forms and data collection for 2 months (August and October 2019), and (C) analysis, compilation of data, and writing the final report over 1 month (November 2019). RESULTS: Sixty-four participants responded. The majority of the respondents were intensivists (50%). Only six respondents (9.5%) had done ECPR at their center with median ECPRs per year of 2 (1-10). All ECPRs were being done in private sector hospitals. The most common indication for initiation was conventional cardiopulmonary resuscitation (CPR) for more than 10 minutes without return of spontaneous circulation (ROSC)(n = 4, 66%). In all cases, the intensivists took decision for the initiation of ECPR. The rest 57 did not have the experience of ECPR at their center due to lack of equipment and experience (50%) and financial issues (50%). CONCLUSION AND CLINICAL SIGNIFICANCE: There is a huge need to increase the awareness of the ECPR program and teams to be trained in India. We also suggest that the tertiary care medical institutions in public sector as well as the private sector that is offering critical care courses should train fellows on ECPR to employ it at times when needed to improve the outcomes of critically ill patients.

Implementation of new ECMO centers during the COVID-19 pandemic: experience and results from the Middle East and India.

PURPOSE: Extracorporeal membrane oxygenation (ECMO) use for severe coronavirus disease 2019 (COVID-19) patients has increased during the course of the pandemic. As uncertainty existed regarding patient's outcomes, early guidelines recommended against establishing new ECMO centers. We aimed to explore the epidemiology and outcomes of ECMO for COVID-19 related cardiopulmonary failure in five countries in the Middle East and India and to evaluate the results of ECMO in 5 new centers. METHODS: This is a retrospective, multicenter international, observational study conducted in 19 ECMO centers in five countries in the Middle East and India from March 1, 2020, to September 30, 2020. We included patients with COVID-19 who received ECMO for refractory hypoxemia and severe respiratory acidosis with or without circulatory failure. Data collection included demographic data, ECMO-related specific data, pre-ECMO patient condition, 24 h post-ECMO initiation data, and outcome. The primary outcome was survival to home discharge. Secondary outcomes included mortality during ECMO, survival to decannulation, and outcomes stratified by center type. RESULTS: Three hundred and seven COVID-19 patients received ECMO support during the study period, of whom 78 (25%) were treated in the new ECMO centers. The median age was 45 years (interquartile range IQR 37-52), and 81% were men. New center patients were younger, were less frequently male, had received higher PEEP, more frequently inotropes and prone positioning before ECMO and were less frequently retrieved from a peripheral center on ECMO. Survival to home discharge was 45%. In patients treated in new and established centers, survival was 55 and 41% (p = 0.03), respectively. Multivariable analysis retained only a SOFA score < 12 at ECMO initiation as associated with survival (odds ratio, OR 1.93 (95% CI 1.05-3.58), p = 0.034), but not treatment in a new center (OR 1.65 (95% CI 0.75-3.67)). CONCLUSIONS: During pandemics, ECMO may provide favorable outcomes in highly selected patients as resources allow. Newly formed ECMO centers with appropriate supervision of regional experts may have satisfactory results.

Vascular access in ECMO.

In critically ill patients, deserving extracorporeal membrane oxygenation (ECMO), choosing the right pattern of cannulation such as veno-venous (VV), veno-arterial (VA), veno-veno-arterial (VVA), and central; selecting the appropriate size cannulae; and good cannulation techniques are all pre-requisites for the successful outcome of ECMO. We are describing the selection criteria for choosing appropriate size cannulae, cannulation configurations, available cannulae, and possible complications. A brief note on anticoagulation was added.

ECMO in India, SWAAC ELSO: challenges and solutions.

The innovations leading to the development of a new technology such as extracorporeal membrane oxygenation (ECMO) and its progress over the years have been inspiring. Many great personalities were associated with the genesis and re-designing the multiple essential components of ECMO to make it more biocompatible. We discussed the brief history of cardiopulmonary bypass and ECMO. We elucidated the establishment of a commanding center, Extracorporeal Life Support Organization (ELSO) in the USA, ECMO society of India in the sub-continent and the birth of South and West Asia Chapter (SWAC) of ELSO initially, which became South and West Asia, Africa chapter (SWAAC) ELSO later after amalgamation of Africa to this sub-chapter of ELSO.

Blunt laryngeal trauma presenting as bilateral massive pneumothoraces and subcutaneous emphysema: a multidisciplinary approach to management.

A 3-year-old boy had an unwitnessed fall from a highchair. The child had no loss of consciousness, vomiting, stridor or respiratory distress but within a few minutes had significant swelling in the neck, scalp and around the eyes. He was brought immediately to the emergency room where he deteriorated rapidly and was intubated with a cuffed oral endotracheal tube. A clinical diagnosis of blunt laryngeal trauma was made. Imaging showed no laryngeal disruption, but did reveal massive bilateral pneumothoraces, that were managed with chest tube. A multidisciplinary meeting with family led to a watchful waiting approach. The patient was successfully extubated at 1 week and healed with a clear voice.

Spontaneous Splenic Hemorrhage in the Newborn.

Spontaneous splenic hemorrhage in the newborn is a rare entity. The presentation is usually with a triad of bleeding, abdominal distension, and hemoperitoneum. Rapid diagnosis is essential as left untreated, death is inevitable. We present a case with an unusual initial presentation of a scrotal hematocele and ultrasonography suggesting an adrenal hemorrhage. At laparotomy, splenic preservation was unsuccessful, and therefore, splenectomy was performed. The child recovered well from the procedure.

Population pharmacokinetics of vancomycin in patients receiving extracorporeal membrane oxygenation.

AIMS: Extracorporeal membrane oxygenation (ECMO) is a life support system used during severe respiratory or cardiorespiratory failure. The objective of this study was to characterize the population pharmacokinetics of vancomycin during ECMO. METHODS: A population model was developed using WinNonMix (Version 2.0.1) from a total of 366 plasma observations in 45 patients, including term neonates, older children and adults. The study utilized both rich prospective and sparse retrospective data. Prospective samples were drawn at baseline and then 30, 60,90, 120, 180, 240, 300, 360 and 420 min postinfusion. Steady state concentrations were obtained retrospectively from an assay database, cross-referencing with the patients' medical records. RESULTS: Data were examined using a two-compartment model with an additive and proportional residual error. Model fit improved substantially when clearance, CL (l kg(-1) h(-1)) was modelled as a nonlinear function of serum creatinine (Cr) micromol l(-1). There was a linear relationship between CL and age up to 1000 days: CL (Age < 1000 days) = [2.4 + 0.0018 x Age (days)]/Cr; CL (Age > 1000 days) = 4.3/Cr. Age also influenced central volume (V1) when included in the model as a dichotomous variable: V1 (Age < 4000 days) = 0.45 l kg(-1); V1 (Age > 4000 days) = 0.36 l kg(-1). Intercompartmental clearance and tissue volume were estimated to be 0.09 l kg(-1) h(-1) and 0.25 l kg(-1), respectively. Model validation in a separate group of 20 patients revealed a bias of -7.7% and a precision of 26.7%. CONCLUSIONS: The clearance of vancomycin was decreased and its volume of distribution increased in patients receiving ECMO, suggesting altered drug disposition during this treatment.

Performance of polymethyl pentene oxygenators for neonatal extracorporeal membrane oxygenation: a comparison with silicone membrane oxygenators.

OBJECTIVE: To review the performance of polymethyl pentene versus silicone oxygenators in terms of efficiency in priming and oxygenation, oxygenator resistance, requirements for coagulation proteins and consumption of blood products, for neonatal extracorporeal membrane oxygenation (ECMO) patients. STUDY DESIGN: Forty consecutive neonates were selected retrospectively pre- and post-introduction of the new polymethyl pentene (PMP) oxygenators. They formed two equal groups. After calculation of the sample size, data were collected from ELSO registry forms and patient records. Results were analysed using parametric and non-parametric tests. RESULTS: Neonatal PMP (N-PMP) oxygenators were smaller, faster and easier to prime. They were less efficient than silicone oxygenators, especially in carbon dioxide elimination, and, therefore, required higher sweeps. The preservation of coagulation proteins was significantly better, but there was no reduction in the consumption of blood products, despite having less than half the surface area and significantly lower blood path resistance. CONCLUSION: Small PMP oxygenators (Medos Hilite 800 LT) provide adequate gas exchange and offer technical advantages in terms of more efficient priming, reduced haemodynamic resistance and better control and preservation of coagulation proteins than silicone oxygenators.

Pneumocephalus in neonatal meningitis: diffuse, necrotizing meningo-encephalitis in Citrobacter meningitis presenting with pneumatosis oculi and pneumocephalus.

UNLABELLED: OBJECTIVE/PATIENT: Gas-containing encephalitis is rarely associated with neonatal meningitis. We report a case of a 19-day-old baby who presented with a rapid onset of septic shock complicated by progressively increasing gas accumulation within the brain and anterior chamber of the eye. We describe the evolution of the clinical picture and the management. INTERVENTIONS: Ventilatory support, fluid resuscitation, and continuous venovenous hemofiltration were provided in view of multiple system failure. Despite effective antibiotic therapy and supportive management, the patient died with worsening accumulation of gas within the brain, resulting in brainstem death. RESULTS: Computed tomographic images were characteristic of diffuse necrotizing meningo-encephalitis. Postmortem examination showed friable brain tissue with venous infarction and extensive gas accumulation. Citrobacter koseri was identified from the blood and cerebrospinal fluid cultures. CONCLUSION: This case re-emphasises the importance of C. koseri as both a community-acquired and nosocomial neonatal pathogen. Radiologic evidence suggestive of diffuse necrotizing meningo-encephalitis in combination with pneumocephalus and pneumatosis oculi in Citrobacter infections has never been described before. Diagnostic imaging with computed tomographic scanning of the brain and initiation of broad-spectrum antibiotics with good penetration into cerebrospinal fluid are indicated as soon as infection with Citrobacter species is suspected clinically, with appearance of pneumatosis oculi as a rare, late finding.

Venovenous extracorporeal membrane oxygenation for respiratory failure in inotrope dependent neonates.

It is often stated that venovenous extracorporeal membrane oxygenation (VV ECMO) should not be used in inotrope dependent patients. It is our practice to use VV ECMO in most patients with respiratory failure even though many of these patients are receiving significant doses of inotropes. Our objective was to review the mode of ECMO in relation to precannulation doses of inotropes administered to neonates treated with ECMO for respiratory failure. Forty-three consecutive case notes were reviewed. Data were collected for basic demographic and ECMO parameters. Inotropic doses were converted to a single score for ease of comparison, with one point equivalent to 1 microg/kg/min dopamine. Forty-three neonates were studied; 37(86%) were treated with VV ECMO and 6 (14%) were treated with VA ECMO. Significant pre-ECMO inotropic support (score > 10) was present in 30 (70%) of the 43 cases. Of these patients, 26 were treated via VV ECMO with a survival rate of 84%, while 4 were treated with VA ECMO with a survival of 75%. Inotrope scores fell to nonsignificant levels (< 10) within 24 hours, regardless of ECMO mode. Mean arterial blood pressure remained above precannulation levels in both groups. VV ECMO allows safe treatment of neonatal respiratory failure in the presence of significant inotropic support. We recommend VV ECMO for neonatal respiratory failure in all cases except where double lumen cannulation is impossible or when septic shock is refractory to inotropic support (i.e., mean blood pressure < 35 mm Hg despite inotrope score of > 100).

Extracorporeal life support in pertussis.

Severe B. pertussis infection in infants is characterized by severe respiratory failure, pulmonary hypertension, leukocytosis, and death. This retrospective case analysis highlights the course and outcome of severe B. pertussis infection treated with extracorporeal membrane oxygenation (ECMO) at a single center. Over the last decade, out of a total caseload of nearly 800 infants and children, 12 infants with severe B. pertussis have been referred for ECMO therapy to our center. All infants with pertussis infection who received ECMO therapy were less than 3 months of age at presentation and unvaccinated. There was a high mortality rate (7 of 12 infants died), which was associated with an elevated neutrophil count at presentation and multiorgan dysfunction characterized by intractable pulmonary hypertension, persistent systemic hypotension, renal insufficiency, and fits. ECMO should be offered to children with pertussis infection and respiratory failure refractory to mechanical ventilation. However, further research is required to determine the optimal management for infants receiving ECMO therapy with this disease.
