Randomized Controlled Trial Clinical TrialPressure and volume changes of tracheal tube cuff following inflation with various inflating agents during nitrous oxide anesthesia.
The study was designed to investigate the changes in pressure and volume of a tracheal tube-cuff inflated with air, mixture of N2O + O2, saline and 4% lidocaine during nitrous oxide anesthesia. This study was conducted in 80 patients (33 male & 47 female). The pressure and volume of a tracheal tube cuff increased with air, decreased with mixture of N2O + O2 and almost remained the same with saline and 4% lidocaine. The complications were more in the air group.

Carotid endarterectomy: a study of cerebral oxygen saturation vs stump pressure.
Carotid endarterectomy (CEA) is an established surgical procedure for treatment of internal carotid artery (ICA) stenosis. To determine whether or not a carotid shunt is necessary to place, some surgeons measure the stump pressure. We conducted the current study in order to identify whether or not cerebral oxygen saturation (rS02%) can serve as another quantitative measurement to determine the need of carotid shunt during CEA. ⋯ rSO2% may serve as another quantitative measurement to determine the need for carotid shunt during CEA surgery. Due to the small number of cases in the current study, the critical rSO2% which warrants carotid shunt placement could not be identified. Therefore, large number of patients are required to define the critical rSO2% during CEA surgery.

Randomized Controlled Trial Comparative Study Clinical TrialThe effect of ketamine and fentanyl in reducing the pain of diazepam injection.
Diazepam is an effective drug that is used widely in modern anesthesia. Venous irritation is one of its major side effects attributed to its acqueous insolubility and requisite solvents. There is some evidence that ketamine may acts as a local anesthetic drug, because of its effect on N-methyl-D-aspartate receptors. ⋯ The pain of diazepam injection was then evaluated at 30 minutes intervals. Our results showed that ketamine and fentanyl reduce the pain of diazepam dramaticaly (p < 0.001) in comparison with placebo. Ketamine is more effective than fentanyl in reducing such pain (p < 0.001).

Randomized Controlled Trial Comparative Study Clinical TrialPain relief after arthroscopic knee surgery--intraarticular sufentanil vs morphine.
Prevention of postoperative pain by injecting opioid into the knee joint is believed to support the hypothesis of peripheral opioid receptor activation in inflammation. Main outcomes were reduction of pain intensity and need for supplementary analgesics. The aim of the present study was to evaluate the analgesic effects of intraarticular sufentanil in comparison with morphine, following arthroscopic procedures of knee joint. ⋯ The Intra-articular injection of morphine and sufentanil, reduce both the post arthroscopic knee procedures pain, and the need for supplementary analgesics. However, sufentanil, 5 microg is more effective than morphine.

Randomized Controlled Trial Comparative Study Clinical TrialRandomized prospective crossover study of biphasic intermittent positive airway pressure ventilation (BIPAP) versus pressure support ventilation (PSV) in surgical intensive care patients.
The aim of this prospective, randomized and crossover study was to assess the role of a relatively new mode of mechanical ventilation, biphasic intermittent positive airway pressure (BIPAP) in comparison to another well established one, pressure-support ventilation (PSV) in surgical intensive care patients. ⋯ PSV and BIPAP can be used for weaning patients comfortably in surgical intensive care after short-term postoperative ventilation. BIPAP may have the credit of being smoother than PSV where no patient effort is required.
