Background: Proper nutritional support is one of the important caring aspects in patients who were hospitalized in ICU. Objective: This study was done to investigate Oral Drop Gastrolit effect on the gastric residual volume (GRV) in mechanically ventilated patients hospitalized in ICU. Methods: In this clinical trial, 50 mechanically ventilated patients were recruited using convenience sampli...

Chest pain caused by myocardial ischemia is mediated by cardiac sympathetic afferents. Although silent nociceptors exist in somatic structures and some visceral organs, their presence in the heart remains uncertain. The present study examined the presence and the functional characteristics of mechanically insensitive cardiac sympathetic afferents using an electrical search technique. Single-uni...

background: the purpose of our study was to evaluate an inexpensive and available method to reduce mucous impactions in mechanically ventilated patients. methods: this randomized clinical trial was conducted on 40 mechanically ventilated patients aged 15-90 years. the patients were randomly allocated into two arms; 20 cases and 20 controls. the cases received n-acetylcysteine via their nebulize...

Inter- and extracellular-mediated changes in intracellular Ca2+ concentration ([Ca2+]i) can ensure coordinated tissue function in the lung. Cultured rat alveolar epithelial cells (AECs) have been shown to respond to secretagogues with increases in [Ca2+]i and have been shown to be gap junctionally coupled. However, communication of [Ca2+]i changes in AECs is not well defined. Monolayers of AECs...

Inhaled bronchodilators are routinely administered to mechanically ventilated patients to relieve dyspnea and reverse bronchoconstriction. A lower percentage of the nominal dose reaches the lower respiratory tract in a mechanically ventilated patient than in a nonintubated subject, but attention to device selection, administration technique, dosing, and patient-ventilator interface can increase...

The care of the mechanically ventilated patient is at the core of a nurse's clinical practice in the Intensive Care Unit (ICU). Published work relating to the numerous nursing issues of the care of the mechanically ventilated patient in the ICU is growing significantly. Literature focuses on patient assessment and management strategies for patient stressors, pain and sedation. Yet this literatu...

background: endotracheal or tracheostomy tube in mechanically ventilated patients disturb verbal communication with others. therefore, patients are frustrated of requesting for their needs or problems related to artificial breathing. therefore investigating self-experiences of these patients can be applied in providing them with a better care by clinical personnel. methods: this is a qualitativ...
