Efficacy of noninvasive nasal mechanical ventilation in acute respiratory failure: monitored by breathing patterns.
Till a decade back, the mainstay delivery of mechanical ventilation to patients with acute respiratory failure was through the endotracheal tube. To obviate the various complications of endotracheal intubation, noninvasive mechanical ventilation (NIMV) techniques were devised which could be used outside the confines of an ICU setting, and have been employed by several workers to achieve a high success rate. ⋯ It was concluded that NIMV resulted in marked improvement in both the breathing pattern and blood gas parameters in patients of ARF; and PaCO2, pH, RR, %RC served as the best indicators of improvement. NIMV was observed to be most useful in those patients who had CO2 retention.

25-30% fatality due to acute pulmonary oedema in victims of Indian red scorpion (Mesobuthus tamulus) sting have been reported from Western Maharashtra, India. The advent of prazosin in recent years has revolutionized the management of severe scorpion sting cases. Majority of cases developed acute pulmonary oedema in 4-8 hours in a hospital setting irrespective of control of their arterial blood pressure with six hourly oral prazosin regimen, these cases recovered with extra dose of prazosin. We developed a standardised protocol for acute phase of treatment of these cases with the aim of preventing the development of pulmonary oedema. ⋯ Compared with NPC management; development of acute pulmonary oedema prevented by standardised protocol regimen at rural setting.
