background: to determine whether using mechanical ventilation in neonatal intensive care unit (nicu) influences motor development of low birth weight (lbw) infants and to compare their motor development with normal birth weight (nbw) infants at the age of 8 to 12 months using peabody developmental motor scale 2 (pdms-2). methods: this cross sectional study was conducted on 70 lbw infants in two...

the main objective of a research program, whose output is presented here, has been to estimate “ventilation coefficients”, a critical parameter in determining air pollution concentration near the surface ground which signifies the ability for natural ventilation of an air shed in an urban or rural area. relevant measured data from the city of tehran has been used to calibrate and further de...

despite the similar performance of bazaar1 in different cities of iran, there are some the skeletal differences between markets in different climates. the bazaar roof protects customers against natural events in any climate. the ceiling height and the sitting down of the bazaar`s floor are determined based on the need for air circulation and movement in various climates. hence, combination of a...

conclusions we found that 0.3 mcg/kg of sufentanil attenuates cardiovascular responses to double-lumen endobronchial intubation without adverse effects. background sufentanil is a potent opioid analgesic frequently used in clinical anesthesia. double-lumen endobronchial intubation induces profound cardiovascular responses in comparison with ordinary endotracheal intubation because of the larger...

background endotracheal suctioning is a necessary procedure practiced by nurses in intensive care units to remove lung secretions. this procedure leads to higher oxygenation levels and reduced breathing difficulties. it also prevents atelectasis, pulmonary infections, and the accumulation of secretions. objectives the present study aims to compare the effectiveness of open and closed endotrache...

conclusions this report presents a new method for lung isolation in specific cases and in the absence of certain equipment. case presentation a 41-year-old woman with a history of pharyngo-laryngo-oesophagectomy (plo) and tracheostomy was a candidate for thoracic duct ligation because of chylothorax. since the patient had tracheostmy stomal stenosis, two cuffed tracheal tubes (internal diameter...

Background: Respiratory distress syndrome (RDS) is a medical emergency in infants resulting from a lack of or deficiency in surfactant, and leads to pulmonary failure. Surfactant and mechanical ventilation are among the primary treatments for helping infants with respiration. Some sedative drugs, such as benzodiazepines and opioids, are used to reduce stress and restlessness in...
