Central venous cannulations are commonly performed in the intensive care unit. However, these may be associated with severe mechanical or bleeding complications. Here, we describe a patient who died following severe and rapid airway obstruction secondary to an arterial trauma during internal jugular vein cannulation. This case report highlights the importance of prompt recognition of arterial trauma so that it can be repaired surgically instead of sheath removal. The prompt diagnosis of an impending airway obstruction and obtaining early airway access cannot be overemphasized. Finally, we discuss the risk factors associated with this complication and what we could have possibly done to prevent this outcome.

A total of 39 non-duplicate isolates of carbapenem-resistant Pseudomonas aeruginosa and Acinetobacter species isolated from blood and endotracheal secretions were tested for metallo-β-lactamase (MBL) production by modified-EDTA disc synergy and double disc synergy tests. The prevalence of MBLs was 33.33% by both the above tests. All patients with MBL-positive isolates were multidrug resistant and had multiple risk factors like > 8 days hospital stay, catheterization, IV lines, previous antibiotic use, etc. These were risk factors for imipenem resistance also. The overall mortality in MBL-positive patients was 46.15%.

Purpose: To study the feasibility of using the pro-seal laryngeal mask airway (LMA) for airway maintenance during bronchoscopic-guided percutaneous tracheostomy. Materials and Methods: Observational study of 60 patients in a 16-bed intensive care unit. The patient's tracheal tube was exchanged for a pro-seal LMA before undertaking percutaneous tracheostomy. Results: Inspiratory pressure and tidal volumes achieved during the procedure were recorded. The median peak inspiratory pressure was 25 (standard deviation 4.4) cm H2O. There was no loss of tidal volume in 30 patients, a loss of less than 100 mL/breath in 27, and loss of more than 100 mL in 3 patients. A pro-seal LMA successfully maintained the airway and allowed adequate ventilation during per-cutaneous tracheostomy in all 60 patients. In all patients, fiber optic bronchoscopy through the pro-seal LMA provided a clear view of the cords and trachea and there was no laryngeal or tracheal soiling at any stage of the procedure. Conclusion: The pro-seal LMA provides a reliable airway and allows effective ventilation during percutaneous tracheostomy. The passage of a fiberscope through the pro-seal LMA and glottis is easy and provides a clear view of the upper trachea.

Thromboembolic disorders are one of the disorders for which we are still on the look out for a safe and efficient drug. Despite the widespread use of antithrombotic drugs for the prevention and treatment of arterial and venous thrombosis, thromboembolic diseases continue to be a major cause of death and disability worldwide. This shows our inefficiency in searching efficacious and safe antithrombotic drugs. We have reached the basic mechanism of thrombus formation and by interrupting various steps of this mechanism, we can prevent as well as treat thromboembolic disorders. In continuation of Aspirin, now, we are using Clopidogrel, Ticlopidine and GpIIb/IIIa inhibitors (Abciximab, Tirofiban and Eptifibatide). Warfarin is an old antithrombotic drug which is still being used; but due to various side effects and drug interactions, we are bound to use newer drugs. Newer antiplatelet drugs include Prasugrel, Ticagrelor and Cangrelor, whereas newer thrombin inhibitors are Ximelgatran and Dabigatran. Apixaban is also a newer entry in this category as factor Xa inhibitor. Idrabiotaparinux is an indirect inhibitor of Xa as it accelerates the activity of antithrombin. Moreover, researches and trials for better and safe drugs are ongoing.

Bronchiolitis obliterans (BO) is an infrequent chronic obstructive pulmonary disease that follows an insult to lower respiratory tract. BO following a severe lung infectious disease is the most common form reported in children. It implies a chronic necrotizing and ultimately fibrosing process affecting the small airways which results in progressive obliteration with resultant obstructive lung disease. The characteristic symptom-complex includes dyspnea, chronic cough, sputum production and wheezing. Although histopathology remains the gold standard for diagnosis, computed tomographic scan is of great help in diagnosis. Etiological role of mechanical ventilation has not yet been studied well. We report a case of BO in a three year old child occurring after an episode of lower respiratory tract infection requiring prolonged mechanical ventilation with subsequent development of ventilator-associated pneumonia. Our patient had a protracted clinical course with good response to corticosteroids.

Cardiac involvement is one of the main complications substantially contributing to the morbidity and mortality of patients suffering from systemic lupus erythematous (SLE). However, clinically important myocarditis is an unusual feature in SLE. We describe the clinical characteristics, management, and outcome of a 15-year young girl with SLE who developed severe left ventricular dysfunction.

Bradycardia in neurosurgery is almost always assumed to be secondary to intracranial conditions, specifically raised intracranial pressure causing Cushing's reflex, the trigemino-cardiac reflex or brainstem lesions. We present a case of posterior fossa surgery in which persistent bradycardia developed in the postoperative period. A cardiac cause was initially overlooked since hydrocephalus was present preoperatively, which was initially assumed to be the cause of the bradycardia. The baseline pulse rate prior to surgery was 66 beats/minute. Only when repeated imaging revealed complete resolution of the hydrocephalus was a cardiology work up done and diagnosis of sick sinus syndrome established. The authors present an interesting case which demonstrates the need for a high degree of suspicion for such rare co-existing conditions. The diagnostic and management dilemmas are further discussed.

Background: The optimal hemoglobin level and transfusion threshold in patients with septic shock treated with an early, goal oriented approach to resuscitation remains unknown. Aims: To assess the impact of packed red blood cell (PRBC) transfusion on clinically relevant outcomes in patients with septic shock treated with early goal directed therapy (EGDT). Settings and Design: Retrospective cohort study of 93 patients who presented with septic shock, to a single center academic intensive care unit and received EGDT. Materials and Methods: Data were collected on patients identified via the Surviving Sepsis Campaign Chart Review database and linked to Project IMPACT database. The PRBC group and no PRBC group were compared by the Pearson chi-square and Fisher's exact test to analyze statistical significance. Results: The PRBC group had a mortality of 41.2% vs. 33.9% in the no PRBC transfusion group (P = NS). The PRBC group also had more mechanical ventilation days (11.2 days vs. 5.0 days, P ≤ 0.05), longer hospital length of stay (25.9 days vs. 12.5 days, P ≤ 0.05), and longer intensive care unit length of stay (11.4 days vs. 3.8 days, P ≤ 0.05). Conclusions: In this retrospective cohort study, transfusion of PRBCs was associated with worsened clinical outcomes in patients with septic shock treated with EGDT. Further studies are needed to determine the impact of transfusion of PRBC within the context of early resuscitation of patients with septic shock, as the beneficial effects gained by an early and goal oriented approach to resuscitation may be lost by the negative effects associated with PRBC transfusion.

Context: Acute symptomatic hyponatremia is a frequent yet poorly studied clinical problem. Aims: To develop a non-weight based protocol for the treatment of acute symptomatic hyponatremia. Settings and Design: Observational study in a Multi-disciplinary Intensive Care Unit of an urban tertiary care hospital. Materials and Methods: Patients aged >18 years, admitted with euvolemic acute symptomatic severe hyponatremia (defined as serum sodium <120 meq/l with symptoms <24 hours), formed the study population. On confirmation of euvolemic status clinically and by laboratory investigations, patients were administered 100 ml of 3% NaCl over a period of 4 hours irrespective of the weight of the patient, followed by reassessment of serum Na at the end of 4 hours. The volume of hypertonic saline (in ml) required to increase serum Na by 8 meq/l was calculated using the formula: 100 × 8/increment in serum Na observed with 100 ml hypertonic saline. This volume was infused over the next 20 hours. To monitor renal water diuresis which may contribute to overcorrection, the urine specific gravity was monitored every 4 hours for sudden decrease of ≥ 0.010 from the baseline value. Measurement of serum Na was repeated if a fall in the urine specific gravity was observed and subsequently repeated every 4 hours. If no fall occurs in urine specific gravity, serum Na measurement was repeated at 12, 20 and at 24 hours (0 hour being the initiation of 100 ml hypertonic saline). The volume of infusate was adjusted if an excessive increment of serum Na (greater than 3 meq at 8 hours, 4 meq at 12 hours, 5 meq at 16 hours and 6 meq at 20 hours) was observed. Baseline characteristics were compared using chi-square test and Mann-Whitney U test. Results: 58 patients formed the study cohort. The mean age was 58 years. The mean serum Na on admission was 114 meq/l. Administration of 100 ml hypertonic saline resulted in a mean increase in serum Na of 2 meq/l. The mean increase in serum Na over 24 hours was 9 meq/l and mean volume of hypertonic saline required for a serum Na increment of 8 meq/l was 600 ml. Conclusions: The non-weight based protocol with monitoring for water diuresis is reasonably an effective strategy in the treatment of acute euvolemic symptomatic hyponatremia.

Aim: As an alternative method for acute blood purification therapy, continuous venovenous hemodiafiltration (CVVHDF) has been reported as an effective clinical treatment for critically ill patients, but the optimal column for performing CVVHDF remains controversial. Patients and Methods: We used direct hemoperfusion using a polymyxin B-immobilized fiber column (DHP-PMX) to treat 88 patients with septic shock. To determine the optimal acute blood purification therapy, we subsequently divided the patients into three groups: the first group underwent CVVHDF using a polymethylmethacrylate membrane hemofilter (PMMA) after undergoing DHP-PMX (28 cases), the second group underwent CVVHDF using a polyacrylonitrile membrane hemofilter (PAN) after undergoing DHP-PMX (26 cases), and the third group did not undergo CVVHDF after undergoing DHP-PMX (34 cases). Results: The overall survival rate was 54.5%, and patient outcome was significantly related to the Acute Physiology and Chronic Health Evaluation (APACHE) II score, the sepsis-related organ failure assessment (SOFA) score, and the blood lactic acid value before treatment (all P<0.0001). Only the PMMA-CVVHDF group showed a better outcome (survival rate of 78.6%) compared with the other groups (P = 0.0190). In addition, only the PMMA-CVVHDF group showed a significant improvement in the blood lactic acid level on day 3 (P = 0.0011). Conclusion: Our study suggests that the PMX column might be effective during the early phase of septic shock, before a high level of lactic acid is present. Furthermore, a PMMA column might be the most useful column for performing CVVHDF after DHP-PMX treatment, as suggested by the blood lactic acid value.

Aim: Peripherally inserted central venous catheters (PICCs) are popular due to the ease of insertion, low cost and low risk of complications. Anteroposterior (AP) chest radiograph (CXR) is then obtained to assess the location of the catheter tip. But poor-quality X-rays remain a significant problem. We planned a study using radiopaque marker at sternal angle, as a radiological landmark, to relate height of the patient and optimal length of PICC fixation, at the antecubital fossa, and to know the incidence of malpositioning. Materials and Methods: A total of 200 patients aged above 20 years, scheduled for elective major cancer surgeries were studied. Vygoflex PUR, 16-G catheter, length 70 cm was used. The right or the left arm was chosen depending on the availability of veins. Catheter tip was observed in the post procedure CXR. Results: 200 patients [100 patients in group 1 (length of catheter fixation at antecubital fossa 45 cm) and 100 patients in group 2 (length of catheter fixation 50 cm)] were enrolled. The groups were further subdivided into 1a, 1b, 2a, 2b and results tabulated. Conclusions : Appropriate length of catheter fixation for group 1a was <45 cm, group 1b = 45 cm, group 2a = 50 cm, and for group 2b it was ≥50 cm. Gender and arm (right or left) did not have any bearing on the length of fixation. Incidence of malpositioning (15.5%) was more in right-sided catheters, more so, in short heighted people. PICC insertion via cubital route stands better compared with other routes, viz., Internal jugular vein IJV, subclavian and femoral.
