Electrolytes imbalance is one of the most prevalent complications among the patients hospitalized in intensive care unit (ICU) and for early detection of it, concentrations of blood gases are measured. But, phlebotomy is related to secondary complications such as infection in these patients. This study aimed to determine the relationship between the concentrations of blood gases and saliva gases in patients hospitalized in internal care units.
This was a cross-sectional study in internal care units of Alzahra hospital, Isfahan, Iran during 2015-2016. 120 patients admitted in internal care unit were selected and amounts of blood gases including pH, partial pressure of carbon dioxide (PCO2), bicarbonate (HCO3), and partial pressure of oxygen (PO2) were measured in blood and saliva and compared between the two samples.
Findings: There were statistically significant direct correlation between the amounts of pH, PCO2, HCO3, and PO2 in blood and saliva (Pearson correlation coefficient of 0.25, 0.74, 0.72, and 0.58, respectively) (P The direct correlation between the concentration of blood and saliva gases suggests that water-electrolyte imbalance probably can be predicted via measuring gases concentration in saliva. This can decrease interventional procedures and finally decrease secondary complications due to repeated phlebotomy in patients hospitalized in intensive care units. More studies are recommended.

Eٍndotracheal suctioning is a method to remove secretions from the airway in patients who can not perform this voluntarily and have an artificial airway. Suctioning is frequently used in the ICUs and can result in many complications if not performed properly. The aim of this study was to compare the effects of hyperoxygenation on arterial blood gases before and after endotracheal suctioning. In this study, 36 patients admitted to the intensive care ward of Bahonar and Afzalipour hospitals that have inclusion criteria were chosen. The subjects were studied in acrossover design. The data collection form was used to record. This form has 2 parts: 1) demographic characteristics and 2) table to record the results of arterial blood sampling and continuous monitoring parameters in patients. Patients were randomly assigned to suctioning with lung hyperoxygenation and combination of hyperoxygenation and hyperinflation before and after suctioning. Arterial blood gases and physiological parameters were recorded pre-intervention and immediately and 30 minutes after intervention. Data were analyzed with SPSS software. Suctioning with both methods can increase PaO2 and O2 saturation immediately and 30 minutes after the suction. However, an increase with combined method is more sensitive. Hyperoxygenation can increase mean of paCO2 immediately and 30 minutes after thesuction but combination of hyper oxygenation and hyperinflation can decrease it. Hyperoxygenation can decrease pH immediately and 30 minutes after the suction but combination of hyper oxygenation and hyperinflation can increase it. Suctioning with both methods can decrease HCO3 however decreasing with hyperoxygenation is moresensitive. Physiological parameters determined immediately and 30 minutes after using a combination of suction with hyperoxygenation and hyperinflation were significantly higher than those with the hyperoxygenation suction method. This study showed that the effect of lung hyper oxygenation and combination of hyper oxygenation and hyperinflation on some of the arterial blood gas and physiological parameters beforeand after endo tracheal suctioning is variable. Among the most important is the influence an oxygen and blood pH. So suctioning can be done suctioned out with either of these two methods, depending on the specific clinical situation of the patients.
