RESUMO

RESUMO Objetivo: Examinar as características clínicas, o padrão de desmame e o desfecho de pacientes que necessitaram de ventilação mecânica por tempo prolongado em uma unidade de terapia intensiva em um país com recursos financeiros limitados. Métodos: Estudo prospectivo observacional em centro único, realizado na Índia, no qual todos os pacientes adultos que necessitaram de ventilação mecânica prolongada foram acompanhados quanto a duração e padrão do desmame, e à sobrevivência, tanto por ocasião da alta da unidade de terapia intensiva quanto após 12 meses. A definição de ventilação mecânica prolongada adotada foi a do consenso da National Association for Medical Direction of Respiratory Care. Resultados: Durante o período de 1 ano, 49 pacientes com média de idade de 49,7 anos receberam ventilação mecânica prolongada; 63% deles eram do sexo masculino e 84% tinham uma enfermidade de natureza clínica. As medianas dos escores APACHE II e SOFA quando da admissão foram, respectivamente, 17 e 9. O tempo mediano de ventilação foi 37 dias. A razão mais comum para início da ventilação foi insuficiência respiratória secundária à sepse (67%). O desmame foi iniciado em 39 (79,5%) pacientes, com sucesso em 34 deles (87%). A duração mediana do desmame foi de 14 (9,5 - 19) dias, e o tempo mediano de permanência na unidade de terapia intensiva foi 39 (32 - 58,5) dias. A duração do suporte com vasopressores e a necessidade de hemodiálise foram preditores independentes significantes de insucesso no desmame. No acompanhamento após 12 meses, 65% dos pacientes sobreviveram. Conclusão: Mais de um quarto dos pacientes com ventilação invasiva na unidade de terapia intensiva necessitaram de ventilação mecânica prolongada. Os desmames foram bem-sucedido em dois terços dos pacientes, e a maioria deles sobreviveu até o acompanhamento após 12 meses.


ABSTRACT Objective: This study aimed to examine the clinical characteristics, weaning pattern, and outcome of patients requiring prolonged mechanical ventilation in acute intensive care unit settings in a resource-limited country. Methods: This was a prospective single-center observational study in India, where all adult patients requiring prolonged ventilation were followed for weaning duration and pattern and for survival at both intensive care unit discharge and at 12 months. The definition of prolonged mechanical ventilation used was that of the National Association for Medical Direction of Respiratory Care. Results: During the one-year period, 49 patients with a mean age of 49.7 years had prolonged ventilation; 63% were male, and 84% had a medical illness. The median APACHE II and SOFA scores on admission were 17 and 9, respectively. The median number of ventilation days was 37. The most common reason for starting ventilation was respiratory failure secondary to sepsis (67%). Weaning was initiated in 39 (79.5%) patients, with success in 34 (87%). The median weaning duration was 14 (9.5 - 19) days, and the median length of intensive care unit stay was 39 (32 - 58.5) days. Duration of vasopressor support and need for hemodialysis were significant independent predictors of unsuccessful ventilator liberation. At the 12-month follow-up, 65% had survived. Conclusion: In acute intensive care units, more than one-fourth of patients with invasive ventilation required prolonged ventilation. Successful weaning was achieved in two-thirds of patients, and most survived at the 12-month follow-up.

RESUMO

Introduction: Introducer needle tip is not clearly visible during the real‑time ultrasound (US)‑guided central vein cannulation (CVC). Blind tip leads to mechanical complications. This study was designed to evaluate whether real‑time US‑guided CVC with a marked introducer needle is superior to the existing unmarked needle. Methodology: Sixty‑two critically ill patients aged 18–60 years of either sex were included in the study. The patients were randomized into two groups based on whether a marked or unmarked introducer needle was used. Both groups underwent real‑time US‑guided CVC by a single experienced operator. Aseptically, introducer needle was indented with markings spaced 0.5 cm (single marking) and every 1 cm (double marking). This needle was used in the marked group. Approximate depths (centimeter) of the anterior and posterior wall of the internal jugular vein, anterior wall of the internal carotid artery, and lung pleura were appreciated from the midpoint of the probe in short‑axis view at the level of the cricoid cartilage. Access time (seconds) was recorded using a stopwatch. A number of attempts and complications such as arterial puncture, hematoma, and pneumothorax of either procedure were compared. Results: Both marked needle and unmarked needle groups were comparable with regard to age, gender, severity scores, platelet counts, prothrombin time, and distance from the midpoint of the probe to the vein, artery, and pleura and skin‑to‑guide wire insertion access time. However, an average number of attempts (P = 0.03) and complications such as hematoma were significantly lower (P = 0.02) with the marked introducer needle group. Pneumothorax was not reported in any of the groups. Conclusion: Our study supports the idea that marked introducer needle can further reduce the iatrogenic complications of US‑guided CVC.

RESUMO

Internal jugular vein (IJV) catheterization is a routine technique in the intensive care unit. Ultrasound (US) guided central venous catheter (CVC) insertion is now the recommended standard. However, mechanical complications still occur due to non‑visualization of the introducer needle tip during US guidance. This may result in arterial or posterior venous wall puncture or pneumothorax. We describe a new technique of (IJV) catheterization using US, initially the depth of the IJV from the skin is measured in short‑axis and then using real time US long‑axis view guidance a marked introducer needle is advanced towards the IJV to the defined depth measured earlier in the short axis and the IJV is identified, assessed and cannulated for the CVC insertion. Our technique is simple and may reduce mechanical complications of US guided CVC insertion.

Staphylococcal sepsis following furunculosis and complicated by deep vein thrombosis and septic pulmonary emboli in a fourteen-yr-old boy is presented. He was managed successfully with antibiotics and anticoagulation.

RESUMO

To find out the incidence of self-extubation in intensive care, to evaluate the factors responsible for it and to identify the predictors of need for re-intubation, a retrospective analysis was conducted among 350 patients who were admitted to the intensive care unit over a two-year period and required ventilatory therapy for more than 48 hours. In all patients who self-extubated, the demographic data, ventilatory parameters before self-extubation (mode of ventilation, inspired oxygen concentration, positive end-expiratory pressure), partial pressure of oxygen in arterial blood and inspired oxygen fraction ration (PaO2/FiO2), and the event of re-intubation were noted. These values were compared among patients who were re-intubated and those who were not. Twelve patients out of 350 self-extubated. Of these 12 patients, 7 required re-intubation while 5 did not. Of these 7 patients, 3 died within 48 hours of the episode of self-extubation and one patient's death was directly attributable to self-extubation. Of the remaining 4 patients, 3 died within a span of 7 days. Re-intubation after self-extubation should not be considered mandatory. Patients who required re-intubation had lower PaO2/FiO2 than patients who did not.
