To compare two different supraglottic airway devices, the laryngeal mask airway (LMA) and the I-gel, regarding easiness of insertion of the device, leak pressure, gastric insufflation, end tidal CO(2), oxygen saturation, hemodynamic and postoperative complications in anesthetized, spontaneously ventilated adult patients performing different non-emergency surgical procedures. ⋯ Both LMA and I-gel do not cause any significant alteration in the hemodynamic status of the patients, end tidal CO(2), and SPO(2). The postoperative complications were not significantly different except nusea and vomiting was statistically significant higher in LMA group (P=0.032). among both LMA and I-gel patients. Insertion of I-gel was significantly easier and more rapid than insertion of LMA. Leak pressure was significantly higher with I-gel than LMA and thus incidence of gastric insufflation was significantly lower with I-gel.

One of the drawbacks of performing ophthalmic surgery under local anesthesia is patient movement, which might affect optimal surgical outcome. ⋯ The combined use of propofol and remifentanil as a continuous infusion before performance of the block and during lengthy vitreo-retinal surgery was associated with a lower incidence of patient discomfort, breakthrough pain, and patient movement along with high degree of surgeons' satisfaction and hemodynamic stability.

The present study compared the efficacy of esmolol and labetalol, in low doses, for attenuation of sympathomimetic response to laryngoscopy and intubation. ⋯ In lower doses, labetalol (0.25 mg/kg) is a better agent than esmolol (0.5 mg/kg) in attenuating the sympathomimetic response to laryngoscopy and intubation.

A study to compare the efficacy between fentanyl and sufentanil combined with low concentration (0.0625%) of bupivacaine for epidural labor analgesia in laboring women ⋯ We conclude that both 0.0625% bupivacaine-fentanyl (2.5 μg/ml) and 0.0625% bupivacaine-sufentanil (0.25 μg/ml) were equally effective by continuous epidural infusion in providing labor analgesia with hemodynamic stability achieving equivalent maternal satisfaction without serious maternal or fetal side effects. We found that sufentanil was 10 times more potent than fentanyl as an analgesic for continuous epidural labor analgesia.

Little is known about the relationship between sedative drugs used preoperatively and postoperative delirium. Melatonin is a drug used to sedate patients preoperatively and is hypothesized by recent works to have a curative effect on postoperative delirium. ⋯ Postoperative delirium is affected with the drug used for preoperative sedation. Melatonin was successful in decreasing postoperative delirium when used preoperatively and in treating more than half of patients developed postoperative delirium when used for three postoperative nights.
