Patient-ventilator asynchrony refers to the uncoupling between the mechanically delivered breath and the patient's respiratory effort. It is common during assisted mechanical ventilation and may affect the morbidity of critically ill patients. Close inspection of pressure, volume and flow waveforms - displayed by modern ventilators - may help the physician to recognize and act appropriately to minimize patient-ventilator asynchrony. During the last two decades new modes of assisted mechanical ventilation have been introduced, aiming to improve patient ventilator synchrony by modulating the triggering function and the variables that control the flow delivery and the cycling off.

Fluid Management in Critical Care: New Insights Into Optimal Fluid Therapy.

Critical Care Medicine, Star Care Multispeciality Hospital, Kozhikode, IND.
Background: Fluid management is a crucial critical care component, influencing outcomes such as organ function, renal integrity, and survival in critically ill patients. Recent evidence suggests that balanced crystalloids may offer advantages over isotonic saline, particularly in reducing the risk of acute kidney injury (AKI) and other complications. This study aimed to evaluate the impact of balanced crystalloids versus isotonic saline on clinical outcomes in the intensive care unit (ICU), focusing on AKI, renal replacement therapy (RRT), and mortality.

The incidence of acute organophosphate (OP) poisoning has steadily increased in developing countries. Many studies showed that oxidative stress could have a significant role in its mechanism. The current study aimed to evaluate the role of N acetylcysteine (NAC) as an antioxidant in acute OP poisoned.

Objectives: This study investigated the implementation of the ABCDEF bundle and the factors associated with its implementation according to national income levels.
Methods: This study is cross-sectional research. We conducted a secondary analysis of an international 1-day point-prevalence study that investigated the implementation of the ABCDEF bundle in critically ill patients.
Extracorporeal Membrane Oxygenation Without Mechanical Ventilation for Recovery From Tracheal Repair.

Postoperative positive pressure ventilation (PPV) can contribute to failure of large intrathoracic airway repairs. We report a case of a 67-year-old woman with severe emphysema who presented with an unstable airway and mediastinitis after full-length transmural intrathoracic tracheal intubation injury. After repair, neither extubation nor PPV distal to the repair was feasible.
