Respiratory and cardiovascular effects of fentanyl during propofol-induced sedation under spinal anesthesia.
To determine whether fentanyl augments respiratory and cardiovascular problems during propofol-induced sedation, we investigated the effects of propofol and fentanyl on respiratory and hemodynamic profiles in 30 female patients under spinal anesthesia, administering oxygen via face mask. ⋯ The combination of fentanyl and propofol augmented the risks of respiratory depression and apnea compared with the use of fentanyl or propofol alone.

Nitric oxide inhalation increases oxygen delivery after cardiovascular surgery in adult patients whether or not they have pulmonary hypertension.
The purpose of this study was to quantify the increase in oxygen delivery (DO2) produced by nitric oxide (NO) inhalation, and to clarify whether NO inhalation might be effective in adult patients after cardiovascular surgery whether or not they have pulmonary hypertension (PH). ⋯ NO inhalation increases DO2 by approximately 20% in adult patients after cardiovascular surgery, irrespective of whether or not they have pulmonary hypertension.
