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.

Comparative StudyReducing cardiovascular responses to laryngoscopy and tracheal intubation: a comparison of equipotent doses of tramadol, nalbuphine and pethidine, with placebo.
The stress response to tracheal intubation may be obtunded by opioids given with induction of anesthesia. Tramadol is an opioid acting on mu-receptors and the monoaminergic pain modulating systems. This study examined vasomotor responses to tracheal intubation after equipotent doses of tramadol, nalbuphine and pethidine (3.0, 0.3 mg/kg(-1), and 1.5 mg/kg(-1), respectively), and placebo, given prior to induction of anesthesia in 118 healthy patients. ⋯ Maximum SAP with tramadol (151 SD 26 mmHg) was similar to that with placebo (157 SD 20 mmHg), but was greater than after pethidine (136 SD 27 mmHg; p < 0.05) and nalbuphine (135 SD 19 mmHg; p < 0.02). With each test drug SAP returned to baseline by the third minute. It is concluded that, in these doses, 1) tramadol does not attenuate the chronotropic nor the inotropic response to tracheal intubation, and 2) pethidine and nalbuphine reduce only the inotropic response to airway instrumentation.
