Patient ventilator asynchrony is a common challenge during noninvasive ventilation, especially when used in acutely unwell patients. Patient ventilator asynchrony often leads to noninvasive ventilation intolerance. If left untreated, this can result in failure of noninvasive ventilation, and hence to intubation and invasive mechanical ventilation,...

Context Pain management intraoperatively and postoperatively in the pediatric age group is a matter of concern. On the one hand, children are poorer at precisely conveying the extent of pain all the while being more susceptible to pain-related complications such as laryngospasm. On the other hand, children are less suited to use of potent opioids d...

Background and Aims In India, the awareness about the psycho-social dimension of chronic pain is minimal among physicians and patients.
