Effect of Positive End-Expiratory Pressure on Central Venous Pressure in Patients under Mechanical Ventilation.
Finding the probable governing pattern of PEEP and CVP changes is an area of interest for in-charge physicians and researchers. Therefore, the present study was designed with the aim of evaluating the relationship between the mentioned pressures. ⋯ The findings of this study revealed the direct relationship between PEEP and CVP. Approximately, a 5 cmH2O increase in PEEP will be associated with about 2.5 cmH2O raise in CVP. When applying a 5 cmH2O PEEP increase, if the baseline PEEP is 0, it leads to a significantly higher raise in CVP compared to when it is 5 cmH2O (2.5 vs. 1.6). It seems that sex, history of cardiac failure, baseline CVP level, and hypertension do not have a significant effect in this regard.

Screening Characteristics of Bedside Ultrasonography in Confirming Endotracheal Tube Placement; a Diagnostic Accuracy Study.
Confirmation of proper endotracheal tube placement is one of the most important and lifesaving issues of tracheal intubation. The present study was aimed to evaluate the accuracy of tracheal ultrasonography by emergency residents in this regard. ⋯ The present study showed that tracheal ultrasonography by trained emergency medicine residents had excellent sensitivity (>90%) and good specificity (80-90) for confirming endotracheal tube placement. Therefore, it seems that ultrasonography is a proper screening tool in determining endotracheal tube placement.

Intravenous Lidocaine versus Morphine Sulfate in Pain Management for Extremity Fractures; a Clinical Trial.
Considering the existing contradictions regarding effectiveness of intravenous (IV) lidocaine, especially in emergency department (ED), the present study was designed to compare the analgesic effect of IV lidocaine and morphine sulfate in pain management for extremity bone fractures. ⋯ Based on the results of the present study, IV lidocaine could be considered as a reasonable alternative choice for pain management in ED.

Intravenous Lidocaine Compared to Fentanyl in Renal Colic Pain Management; a Randomized Clinical Trial.
Using alpha blockers such as intravenous (IV) lidocaine has been deemed effective in controlling acute pain. Therefore, the current study was designed with the aim of evaluating the efficiency of IV lidocaine in comparison to IV fentanyl in pain management of patients with renal colic in emergency department (ED). ⋯ Although mean pain severity was not significantly different between IV fentanyl and lidocaine at various times after injection, treatment failure rate was significantly higher in the IV lidocaine group 15 minutes after injection.

Intranasal Lidocaine for Primary Headache Management in Emergency Department; a Clinical Trial.
Most of the headache cases only require pain management in emergency department (ED). The present study aimed to evaluate the efficacy of intranasal lidocaine in this regard. ⋯ It seems that, intranasal lidocaine along with IV chlorpromazine could result in more successful and faster management of primary headaches in ED.
